parker接头、派克接头简介
parker 接头简介Parker 接头，是美国ParkerHannifin 公司德国工厂的德国工程师Ermto（埃米托）发明于上世纪30 年代，为了纪念其用其名字命名为parker接头，parker接头又名parker卡套式管接头。
Parker接头在中国------parker 接头特性：派克卡套式管接头因其特有的装配方便（仅需两把扳手）而广受欢迎。
经过近80多年的发展，EO工厂始派克接头图册(7张)终保持着卡套式管接头技术的领先地位。
今天，parker管接头是世界上使用最为广泛的一种管接头。
EO管接头是为公制管子设计的，历史上曾经依照德国标准DIN3861、DIN3859和DIN2353，现在这些标准已被国际标准ISO8434取代。
Parker管接头以体积小，压力等级高而著称。
分为低压、中压和高压三个系列（LL、L、S系列）这样使得各种不同的应用场合可以实现最经济化和空间最小化的方案。
parker 接头材质及规格Parker 管接头的材料除了最常见的碳钢镀锌以外，还提供铜和不锈钢两种材料，以适应不同的流体或环境条件。
Parker不锈钢接头的螺母螺纹采用镀银并预先润滑（规格15L-42L，12S-38S），较小规格的螺母螺纹采用蜡封，这样不仅有效的消除了不锈钢螺纹的咬合现象，同时减少40%装配拧紧力矩。
Parker管接头具有50多种不同的形式，可供各种不同应用场合的灵活选择，加上许多parker功能管接头，如旋转接头、球阀、单向阀、截止阀、测压接头等与parker 管接头配合使用，可大大方便系统的配套，提高系统密封的可靠性。
PARKER 液压软管具有防腐、耐高温、抗拉强度高，柔韧性好等诸多性能，而被广泛采用在各行业的液压工程中，派克软管有一层至多层钢丝编织增强层（6层以上），有低、中、高、超高三种压力等级，有轻、重两系列，公称通径在3 — 32mm。
有普通型和特殊型两种软管以满足在普通环境及特殊环境下使用，先进的不剥胶软管极大减轻装配劳动强度，广泛应用在各行业液压系统管路中。
派克软管接头密封形式讲解
软管接头的型式确定其实可以从外观、密封表面形式及螺纹形式来确定。
通过外观可以判断是直接头，还是弯接头等等，而各种接头的螺纹形式从外表看起来都比较类似，为正确分辨就需要用到螺距规或者卡尺等专业的测量工具。
今天，我们就针对密封形式来进行讲解，看如何先通过密封来确定接头的大概型式。
软管接头的密封形式：
螺纹
O型圈
配合角度或金属—金属连接
带O型圈及相关配合的角度
螺纹：外螺纹和内螺纹连接后其牙型之间的挤压可形成密封，典型的螺纹密封连接形式为锥螺纹密封。
O形圈：外螺纹接头上的O形圈挤压在相应的内螺纹配合面上形成了密封，在高压系统里通常采用这种密封型式。
配合角度或金属与金属硬密封：螺纹锁紧后，一定角度的金属斜面相互契合并紧密的挤压在一起产生形变后形成密封。
带O型圈的斜面：这种接头将金属斜面密封和O形圈密封两种方式结合在一起，当锁紧螺母时，密封面相互契合，并使O形圈在两者之间变形。

It is rounded to correspond to internationally standardised ratings. Logical series of fittings are grouped together, with the nominal pressure of the group being that of the “lowest common denomi-nator” within the group.Internationally, these nominal pressures are recognised and serve to match common sizes of components together. Parker tube fittings meet or exceed common standardised pressure rat-ings.T o prove the long term dynamic load resistance, components are tested under pressure impulse conditions of PN × 1.33, at 1Hz for 1 million cycles. Static test burst pressures are at least 4 times the PN value.Exception: for ball valves the static test burst pressures are at least 1.5 times the PN value according to DIN 3230 T5 and ISO5108.Permissible operating temperatureAmbient temperature of hydraulic and pneumatic applications Temperature not permissibleSealings NBR e.g. N552-90, Perbunan (registered trademark of Bayer) FKM e.g. V894-90EPDM e.g. E540-80PTFE e.g. T eflon® (registered trademark of DuPont)POM e.g. Delrin (registered trademark of DuPont)MaterialsFittings Raw materialMaterialFitting typeEO O-Lok®Triple-Lok®Designation2)MaterialNo.Standard USDesignation2)Bodies Nuts Ferrules WeldfittingsBodies Nuts Sleeves Bodies Nuts SleevesSteel Barstock 11SMnPb30 1.0718 DINEN10277-3SAE 12L14X X X X X Free cuttingsteel11SMn30 1.0715 DINEN10277-3SAE 1213X46S20 1.0727DINEN10277-3SAE 1146XForgings15S10 1.0710DIN 1651XFree cuttingsteel11SMn30modified1.0715 DINEN10087SAE 1213modified X X 36SMn14 1.0764 DINEN10087XC45 modified 1.0503 DIN EN10083SAE 1045modified X X X ExtrusionsteelC10C 1.0214 DIN EN SAE C1010X X X X X WeldablesteelC15 1.0401DIN10277-3XOther Steel at the manufacturers discretion special heat treated X XStainless steel Barstock X6CrNiMoTi17-12-21.4571 DINEN10088ANSI 316TIX X XX2CrNiMo17-13-21.4404 DINEN10088ANSI 316LX X X X X X Forgings X6CrNiMoTi17-12-21.4571 DINEN10088ANSI 316TIX X XX5CrNiMo17-12-21.4401 DINEN10088ANSI 316X X X X X X Other Stainless steel at the manufacturers discretion special heat treated XBrass Barstock CuZn35Ni2 2.0540 DIN17660X X XASTMB16/B453CA360/345X X X X X X Forgings CuZn35Ni2 2.0540 DIN17660XASTMB124CA377X X1) Non standard fitting types like e.g. banjo fittings, rotary fittings, adjustable fittings with locknut and flanges might be made from different materials.2) Equivalent materials may be usedForging: 11 SMn 30+Bi (similar to 1.0715/DIN EN 10087)Straight: 11 SMn Pb30 (1.0718/DIN EN 102773)Surface treatmentParker tube fittings from steel are delivered worldwide with a high quality surface protection:Galvanic zinc plated and bright passivated with special sealer (suffix CF).Why zinc plated?The requirements for corrosion resistance of tube fittings have been increasing in the past few years. Increasingly tube systems are not painted. Higher demands are re-quested also for an aesthetic point of view.The traditional black-grey surface “phosphated and oiled” (Znphr5f – DIN 50942) used for tube connections in the past does not longer meet these demands. An galvanized deposit zinc layer offers the following advantages: The cor-rosion resistance increases significantly due to a plating of min. 8 R and additional sealing by chromating process. In case of scratches or nicks – which are unavoidable d uring assembly – zinc develops a cathodical protection of the steel fitting body against localised corrosion and abrasion.The corrosion resistance of the CF surface is 400% above zinc plated surfaces to meet highest requirements. The CF surface is also Cr(VI)-free to avoid any contamination in the manufacturing process and meets current regulations e.g. European “End of Life Vehicles“ directive.The silver bright colour due to the chromating or passiva-tion process offers an attractive appearance.All major TFDE manufacturing locations are equipped with their own modern galvanic plants. The process control is specially orientated to the tube fitting product.The users of Parker fittings benefit from:– homogeneous thickness of plating (average 13 μm), measured on outside contour for good screwable threads– high quality above-average concerning avoidance of nicks– very good corrosion resistanceContinuous corrosion tests like salt spray tests according to ISO 9227/5% NaCI show an average resistance of 500 hr in contrast to white rust and 700 hr in contrast to red rust for CF surfaces.Particular fitting series or fitting components and valves are delivered with other or modified surfaces for functional reasons or for better differentiation.Surface protection/SurfaceMaterial Fittingsystem Fitting type CF/Cr3*Zinc platedbrightpassivatedCF+ GlidecoatingA3KZinc platedbrightpassivatedZnphr5fblackphosphatedPlainno coatingPlain+ GlidecoatingPlain+ InsidesilverSteel EO-2Fitting bodies XFunctional nuts XEO Fitting bodies XNuts XProgressive stop rings XWeld fittings X EO2-FORM Bodies and nuts from EO are usedO-Lok®Fitting bodies XNuts XParflange® sleeves XBrazing sleeves X Triple-Lok®Fitting bodies XNuts XSleeves XStainless steel EO-2Fitting bodies XFunctional nutsup to 12-L/10-SXFunctional nutsfrom 15-L/12-S XA3K according to DIN EN ISO 4042 / Znphr5f according to DIN EN ISO 3892 and DIN 50942O-Lok and Triple-Lok parts are plated Cr3 and conform to FC-F01 specification, 120 hours to white rust, 240 hours to red rust.Fluid compatibilityBoth metal fitting material and elastomeric seal compound have to be selected according to the fluid used.Standard recommendations for static seals based on experience and sealing compound manufacturers specification.

This might cause the defect of the connection.This fluid compatibility chart is only applicable on so called “static seals”, such as O-rings and profile sealing rings (e.g. ED-seal, DOZ-seal) in tube fitting and flange systems.For fluid compatibility data of valves, rotary fittings or other multi-function components please review the relevant product pages.Fitting material Sealing materialFluidSteel Stainless steelBrass NBR FKM EPDM Sea Water323111SHELL, Naturelle HF-E-4611X 113SHELL, Tellus Oil DO 3211X 113Silicone oil 11X 111Skydrol 500113331Skydrol 7000113321Soap solutions 313111Steam212331Stoddard solvent 112113Sulphur dioxide 313331Sulphuric acid 323313T oluol111323T ransmission fluid 111113T richlorethane 21X 313Turpentine 213113Water 2112)121Xylol 111313Biodegradable oilsDue to environmental concerns and new legislation bio-degradable oils are rapidly gaining importance for both mobile and stationary applications. The usage of non-in-flammable fluids will remain limited to special applications like mining, steel mills and heavy machines.MediaBiodegradable oils can be classified into 3 categories: HEPG (Glycol based fluids)+ Wide temperature range (–45°C … 100°C)+ Very stable against ageing+ NBR and FKM seals are compatible+ Moderate viscosity change with temperature+ Water soluble– Not mixable with mineral oils or HEES, HETG types– Careful flushing recommended when changing from mineral oil– Paints can be dissolved– Care required with material compatibility(e.g. do not use any zinc containing materials)– Density > 1,100 kg/m3 possible design changes– Price?HETG (Vegetable-based fluids)+ Mixable with mineral oils+ Normal sealing material are compatible(e.g. NBR or FKM)+ Good lubricating properties+ Paint resistant to fluid+ Viscosity changes with temperature are moderate– Limited temperature range (–25°C to +70°C)– Max. temperature not to be exceeded– Limited lifetime– UV and ozone sensitive– Beware of water take-up (cracking?)– Price?HEES (Synthetic ester based fluids)+ Wide temperature range(–30°C … +90°C or over 100°C with some variants)+ Good lifetime+ Mixable with mineral oils+ Normal sealing materials compatible(FKM and NBR recommended)+ Machine paints resistant to fluid+ Viscosity changes with temperature are moderate+ Good lubricating properties– Danger of hydrolysis with water take-up(filters, dryer, occlusion)– Price?CompatibilityGenerally, TFDE steel fittings with standard NBR seals aresuitable for most applications.Suitable sealing compoundsExperience shows that media compatibility is not a critical issue for static seals used on tube fittings. In doubt p lease contact TFDE application engineering.Pragmatic approachIf there is doubt about switching over to softseal fitting s ystems (ISO6149/Eolastic/O-Lok®/EO-2), it might be a good idea to have a close look on the existing hydraulic system. If NBR seals perform well on hoses, cylinders, valves or filters there is nothing to worry about standard TFDE fittings. Usually the design engineers know when special seal compounds like FKM have to be used.。
