分别介绍美国ASCO电磁阀的结构特点与工作原理以及安装
分别介绍美国ASCO电磁阀的结构特点与工作原理以及安装一、简介美国ASCO电磁阀是一种用于掌控液体和气体流动的电掌控元件。
作为一种广泛应用的自动化设备，电磁阀广泛应用于各种工业领域，如石油、化工、航空、军事、水处理、制药、食品等领域。
在现代工业自动化系统中，ASCO电磁阀通常是起掌控作用的中央元件之一、二、结构特点美国ASCO电磁阀的结构包括导管、活塞、阀门和线圈。
其结构特点如下：1.导管——由高质量的铜或不锈钢制成，具有优越的耐用性和防腐性能；2.活塞——是电磁阀的核心部件，其功能在于隔断或通导流体管道；其通常由高强度的不锈钢材料制成，具有良好的抗腐蚀性和耐久性；3.阀门——也称作永磁核，由铜制成，并通过电磁力与活塞密封，防止流体漏出；4.线圈——紧要由高质量的铜线和里芯构成，其作用在于产生磁场，以掌控活塞的移动；三、工作原理美国ASCO电磁阀的工作原理是依靠电信号驱动，通过电磁铁产生的磁场来掌控阀门的状态，从而达到管道中的流体掌控。
实在来说，当电磁铁通电时，纵向线圈内电流产生磁力，使得阀门铁芯处于吸合状态，此时活塞和阀门吻合，流体被阀门和活塞隔开，阀门关闭状态被保持。
相反，当电磁铁断电时，吸合力减弱，阀门闭合弹簧将其关闭，此时，活塞会脱离阀门，流体开始流动。
美国ASCO电磁阀可以依据需要单独安装，也可以与其他设备一起搭配使用。
在不同的工业场合，需要设计不同的电磁阀掌控方案，以实现掌控和调整流量等功能。
四、安装美国ASCO电磁阀的安装应当遵守以下基本要求：1.电磁阀应当安装在水平或者垂直管道上；2.安装时应当确保流体的进出方向与电磁阀的正负极相匹配；3.安装前应当清洗管道，并确保管道内部没有异物或者污垢；4.安装时应当使用密封垫等密封材料，以防止漏水；5.安装后应当进行试运行和调试操作，确保电磁阀的工作正常。
除此之外，当需要进行维护时，需要通过拆除连接螺栓和管道来拆卸电磁阀。
在拆卸时，应当遵奉并服从相应的拆卸步骤和要求，以保证拆卸的正常进行，并防止损坏电磁阀。

This manual provides necessary requirements for meeting the IEC 61508 or IEC 61511 functional safety standards.1.1 Terms and Abbreviations• Process Valve Any valve that is used to control the flow of media being used in a process.For the purpose of this document, this is usually a 2-way valve whosemovement is being controlled by an actuator and pilot valve.• Pilot Valve A 3-way or 4-way valve that is used to send or remove pressurized mediato and from an actuator for the opening and closing of a process valve.• Direct Acting Refers to a solenoid valves main orifice that is opened and closed as adirect result of the solenoid valves electromagnetic movement when thecoil is energized and de-energized.• Indirect Acting Refers to a solenoid valve’s main orifice that is opened and closed as aresult of fluid flow being directed from the electromagnetic 3-way solenoidpilot.• Safety Freedom from unacceptable risk of harm• Functional Safety The ability of a system to carry out the actions necessary to achieve or tomaintain a defined safe state for the equipment / machinery / plant /apparatus under control of the system• Basic Safety The equipment must be designed and manufactured such that it protectsagainst risk of damage to persons by electrical shock and other hazardsand against resulting fire and explosion. The protection must be effectiveunder all conditions of the nominal operation and under single faultcondition• Safety Assessment The investigation to arrive at a judgment - based on evidence - of thesafety achieved by safety-related systems• Fail-Safe State The state where the solenoid is de-energized and its return spring holdsthe pilot in the closed position.• Fail Safe Failure that causes the valve to go to the defined fail-safe state without ademand from the process.• Fail Dangerous Failure that does not respond to a demand from the process (i.e. beingunable to go to the defined fail-safe state).• Fail Dangerous Undetected (DU) Failure that is dangerous and that is not being diagnosed byautomatic stroke testing.• Fail Dangerous Detected (DD) Failure that is dangerous but is detected by automatic stroke testing.• Fail No Effect Failure of a component that is part of the safety function but that has noeffect on the safety function.• Low Demand Mode Mode, where the frequency of demands for operation made on a safety-related system is no greater than twice the proof test frequency.1.2 Acronyms• FMEDA Failure Modes, Effects and Diagnostic Analysis• HFT Hardware Fault Tolerance• MOC Management of Change: These are specific procedures often done whenperforming any work activities in compliance with government regulatoryauthorities.• PFD AVG Average Probability of Failure on Demand• SFF Safe Failure Fraction, the fraction of the overall failure rate of a device thatresults in either a safe fault or a diagnosed unsafe fault.• SIF Safety Instrumented Function, a set of equipment intended to reduce therisk due to a specific hazard (a safety loop).• SIL Safety Integrity Level, discrete level (one out of a possible four) forspecifying the safety integrity requirements of the safety functions to beallocated to the E/E/PE safety-related systems where Safety Integrity Level4 has the highest level of safety integrity and Safety Integrity Level 1 hasthe lowest.• SIS Safety Instrumented System – Implementation of one or more SafetyInstrumented Functions. A SIS is composed of any combination ofsensor(s), logic solver(s), and final element(s).2 D esigning a Safety Instrumented Function (SIF) using an ASCOSolenoid Valve2.1 Safety FunctionWhen de-energized, the ASCO Solenoid Pilot Valve moves to its fail-safe position. Depending on the solenoid specified Normally Closed (NC) or Normally Open (NO), the valve will supply the fluid media or vent the fluid media depending on the piping of the installation. Please note that the solenoid pilot valve must be piped to the actuator in accordance with the manufacturer’s recommendations and allowable desired function.The valve is intended to be part of final element subsystem as defined per IEC 61508 and the achieved SIL level of the designed function must be verified by the designer.2.2 Environmental limitsThe environmental limits of each solenoid are specified in the products respective catalog and Installation & Maintenance Instructions. The designer of a SIF must check that the product is rated for use within the expected environmental limits.2.3 Application limitsThe application limits of an ASCO Solenoid are specified in the products respective catalog and Installation & Maintenance Instructions. It is especially important that the designer check for material compatibility considering on-site chemical contaminants and air supply conditions. If the solenoid valve is used outside of the application limits or with incompatible materials, the reliability data provided becomes invalid.2.4 Design Verification• A detailed Failure Mode, Effects, and Diagnostics Analysis (FMEDA) report is available from ASCO.This report details all failure rates and failure modes as well as the expected lifetime.•The achieved Safety Integrity Level (SIL) of an entire Safety Instrumented Function (SIF) design must be verified by the designer via a calculation of PFD avg considering redundant architectures, proof test interval, proof test effectiveness, any automatic diagnostics, average repair time and the specific failure rates of all products included in the SIF. Each subsystem must be checked to assure compliance with minimum hardware fault tolerance (HFT) requirements. The Exida exSILentia tool is recommended for this work.•When using an ASCO Solenoid in a redundant configuration, a common cause factor of 5% should be included in safety integrity calculations.•The failure rate data listed the FMEDA report is only valid for the useful life time of an ASCO Solenoid.The failure rates will increase sometime after this time period. Reliability calculations based on the data listed in the FMEDA report for mission times beyond the lifetime may yield results that are too optimistic, i.e. the calculated Safety Integrity Level will not be achieved.2.5 SIL Capability2.5.1 Systematic IntegrityThe product has met manufacturer design process requirements of Safety Integrity Level (SIL) 3. These are intended to achieve sufficient integrity against systematic errors of design by the manufacturer. A Safety Instrumented Function (SIF) designed with this product must not be used at a SIL level higher than the statement without “prior use” justification by end user or diverse technology redundancy in the design.2.5.2 Random IntegrityThe solenoid valve is a Type A Device. Therefore when used the only component in a final element subassembly, a design can meet SIL 3 @ HFT=1 and SIL 2 @ HFT=0.When the final element assembly consists of many components (solenoid valve, quick exhaust valve, actuator, isolation valve, etc.) the SIL must be verified for the entire assembly using failure rates from all components. This analysis must account for any hardware fault tolerance and architecture constraints.3 Installation and Commissioning3.1 Installation•The ASCO Solenoid valve must be installed per standard installation practices outlined in the Installation Manual.•The environment must be checked to verify that environmental conditions do not exceed the ratings.•The ASCO Solenoid must be accessible for physical inspection.•Instrument Air Filtration: These solenoids are intended for use on clean, dry air or inert gas filtered to50 microns or better. To prevent freezing, the dew point of the media should be at least 18°F(10°C)below the minimum temperature to which any portion of the clean air or gas system could be exposed.Instrument air in compliance with ANSI/ISA Standard S7.3-1975 (R1981) exceeds the above requirements and is, therefore, an acceptable medium for these valves.• It is the operator’s responsibility to only use design options such as latches, when it is safe to do so.• Typical 3-way pilot valve piping configurations:a. 1 out-of 1 – This is the most common pilot valve configuration used.b. 2 out-of 2 – This is commonly used for high availability applications. In the case that onesolenoid valve was to spuriously trip, the second solenoid still maintains the position of theactuator/process valve at its operating state. Both solenoids must close in order to shift theactuator/process valve to its non-operating state.3.2 Response TimeThe response time of a solenoid pilot valve will vary by design. The factors that affect response time are pilot valve orifice size, operating pressure, size of actuator, torque required to open and close process valve, and distance between pilot valve and actuator. It is the responsibility of the end user to use a pilot valve that delivers the correct opening and closing time of the process valve required for the application.4 Operation and Maintenance4.1 Proof test without automatic testingThe objective of proof testing is to detect failures within an ASCO Solenoid that are not detected by any automatic diagnostics of the system. Of main concern are undetected failures that prevent the safety instrumented function from performing its intended function.The frequency of proof testing, or the proof test interval, is to be determined in reliability calculations for the safety instrumented functions for which an ASCO Solenoid is applied. The proof tests must be performed more frequently than or as frequently as specified in the calculation in order to maintain the required safety integrity of the safety instrumented function.The following proof test is recommended. Any failures that are detected and that compromise functional safety should be reported to ASCO.Table 11Bypass the safety PLC or take other appropriate action to avoid a false trip, following company Management of Change (MOC) procedures2Inspect the external parts of the solenoid valve for dirty or clogged ports and other physical damage. Do not attempt disassembly of the valve.the 3De-energize the solenoid coil and observe that the actuator and valve move. Energize solenoid after a small movement of the valve.4Inspect the solenoid for dirt, corrosion or excessive moisture. Clean if necessary and take corrective action to properly clean the air supply. This is done to avoid incipient failures due todirty air.5Record a n y failures i n your c o m p a n y’s S I F i n s p e c t i o n d a t a b a s e. Restore the loop t o full operation.6Remove the bypass from the safety PLC or otherwise restore normal operationThis test will detect approximately 99% of possible DU failures in the solenoid (Proof Test Coverage).The person(s) performing the proof test of an ASCO Solenoid should be trained in SIS operations, including bypass procedures, solenoid maintenance and company Management of Change procedures. No special tools are required.4.2 Proof test with automatic partial valve stroke testingAn automatic partial valve stroke testing scheme that performs a full stroke of the solenoid valve and measures valve movement timing will detect most potentially dangerous failure modes. It is recommended that a physical inspection (Step 2 from Table 1) be performed on a periodic basis with the time interval determined by plant conditions. Maximum inspection interval is five years but an annual inspection is recommended.4.3 Repair and replacementAccording to section 7.4.7.4 of IEC 61508-2 a useful lifetime based on experience, should be assumed. General field knowledge suggests that most solenoid valves have a useful life of 3 to 10 years, but may be longer depending on the valve series and other factors.It is the responsibility of the end user to establish a preventative maintenance process to replace all solenoids before the end of the useful life.4.4 ASCO NotificationAny failures that are detected and that compromise functional safety should be reported to ASCO Valve.

15/R 03USOLENOID VALVESno voltage release (tamperproof)manual reset construction1/4213FEATURES• The valves are certified according to IEC 61508 Functional Safety data and have SIL-3 capability (Exida approval)• Compact Tamperproof/Manual Reset function which means that the valve has to be energized as well as manually operated before it stays in the "latched" position. Because of the tamperproof feature there will be no flow from port 3 to port 2 if only the push button is pressed. The No Voltage Release (NVR) function will make sure that the valve trips when de-energized• The solenoid valves are recommended for pilot applications with basic flow, wide pressure ranges and no minimum operating pressure• PTFE rider rings and graphite-filled PTFE seals reduce friction and eliminate sticking• Coils used in metal enclosures have class H insulation materials• Peak voltage suppression diodes are standard in DC solenoids with metal enclosures• The solenoid valves satisfy all relevant EC DirectivesGENERALDifferential pressure 0 - 10 bar [1 bar = 100kPa]Maximum viscosity 65 cSt (mm 2/s)Response times75 - 100 msfluids (✶)temperature range (TS)(1)seal materials (✶)air, inert gas, water, oil-20 to +120°C -50 to + 60°CFPM (fluoroelastomer)(F)VMQ ((sillicone)(1)Can be limited by the operator ambient temperature range for explosion proof solenoidsMATERIALS IN CONTACT WITH FLUID(✶) Ensure that the compatibility of the fluids in contact with the materials is verifiedBrass bodyStainless steel body Body Brass AISI 316Stem Stainless steel Stainless steel Core tube Stainless steel Stainless steel Core and plugnut Stainless steel Stainless steel Springs Stainless steel Stainless steel Sealings and poppets FPM or (F)VMQFPM or (F)VMQ Rider Ring PTFE PTFEBPMPRPLP1,8W 3,6W - 3,7W 5,7W - 5,8W Not Available Low powerReduced powerMedium powerBasic powerPOWER LEVELS - cold electrical holding values (watt)SPECIFICATIONSpipe size orificesizeflowcoefficientKv operating pressuredifferential (bar)powerlevel prefix optional solenoidsbasic catalogue number min.max.

通过对电磁线圈通电或断电，可以控制阀门的开启和关闭，从而实现对流体的控制。
ASCO 电磁阀531 的工作原理如下：当电磁线圈通电时，会产生磁场吸引铁芯，从而使阀门打开；当电磁线圈断电时，磁场消失，阀门在弹簧的作用下关闭。
通过控制电磁线圈的通断电，可以实现对阀门的精确控制。
ASCO 电磁阀531 广泛应用于工业自动化、水处理、暖通空调等领域。
例如，在水处理系统中，可以用于控制水的流量和方向；在暖通空调系统中，可以用于控制空调设备的启停和风量调节。
ASCO 电磁阀531 具有以下优点：1.操作简便，安装维护方便；2.性能稳定，使用寿命长；3.适应性强，能应对各种工况。
然而，它也存在一定的缺点，如在高温、高压等特殊工况下，需要选择更为专业的电磁阀。
总之，ASCO 电磁阀531 是一款性价比较高的电磁阀产品，适用于大多数工业自动化领域。
电磁阀(ASCO-JOUCOMATIC)使用说明
2011-9-817:30:29ASCO-JOUCOMATIC电磁阀使用说明ASCO-JOUCOMA TIC电磁阀它是一种直动和先导式相结合的原理，当入口与出口没有压差时，通电后，电磁力直接把先导小阀和主阀关闭件依次向上提起，阀门打开。
当入口与出口达到启动压差时，通电后，电磁力先导小阀，主阀下腔压力上升，上腔压力下降，从而利用压差把主阀向上推开；断电时，先导阀利用弹簧力或介质压力推动关闭件，向下移动，使关闭。
ASCO-JOUCOMA TIC电磁阀特点：在零压差或真空、高压时亦能可动作，但功率较大，要求必须水平安装。
先导式：原理：通电时，电磁力把先导孔打开，上腔室压力迅速下降，在关闭件周围形成上低下高的压差，流体压力推动关闭件向上移动，打开；断电时，弹簧力把先导孔关闭，入口压力通过旁通孔迅速腔室在关阀件周围形成下低上高的压差，流体压力推动关闭件向下移动，关闭。
ASCO-JOUCOMA TIC电磁阀特点：流体压力范围上限较高，可任意安装(需定制)但必须满足流体压差条件ASCO-JOUCOMATIC在电磁阀和机械阀方面，提代了一个广泛的选择，其中流体可以是易燃、易爆介质或腐蚀性介质。
压力可达到150巴，温度可以从-50到300。
口径主要有从1/8英寸到6英寸，操作形式有常闭型，常开型和通用型的2，3，4，5通电磁阀。
