手动阀门使用说明

手动阀门使用说明
手动阀门是常用的阀门之一，包括有手动蝶阀、手动闸阀、手动球阀、手动截止阀等等，本文为您介绍一下手动阀门使用说明。

1、手动阀门的操作需要操纵阀门的人员握住手柄或手轮进行操作，不能够借助杠杆和长扳手来开关阀门，避免用力过猛对手柄或手轮造成损坏，更不能暴力操作，避免事故发生。

通常情况下，手柄的长度或手轮的直径小于320mm，只允许单人进行操作；手轮的直径等于或大于320mm时，允许两个人共同操作完成，也可以单人适当借助工具，杠杆或扳手进行操作，但要注意杠杆长度不可超过0.5m。

2、手动闸阀和手动截止阀都是借助手轮进行操作，在阀门完全开启或关闭之后，要回转1/4~1/2圈，让螺纹之间更好的密合，同时也能避免阀门拧得过紧出现损坏。

3、操作手动蒸汽阀门，在开启前要先对管道进行预热，排出管道中的凝聚水；开启阀门的速度要慢，以防水锤现象的发生，对阀门和管道设备造成损坏。

4、常开的手动阀门密封面上，很容易粘上杂质和脏物，在关闭闭合之前，微微开启一条缝，可以让高速流动的介质冲走这些异物，然后再轻轻关闭，提高密封效果。

5、在一些过高温介质的管道中，当手动阀门关闭之后，阀体内温度下降，因为热胀冷缩导致阀件收缩，密封面会出现一些细小的缝隙，阀门会出现泄漏。

在这种情况下，要在关闭手动阀门之后，过一会儿再关闭一次。

Ruelco MP-4 手动启动的三位一体式手动阀门操作指南说明书

“MP-4”MANUAL RELAYMODEL 1901OPERATION MANUAL OMP # 1901 08/02 Revision 0I. PRINCIPLE OF OPERATIONThe Ruelco “MP-4” relay is a pilot operated manual relay. It is a three (3) way, normally closed valve with a palm knob for relay position indication and manual operation. In the closed position, pneumatic or hydraulic pressure coming into the “Inlet” port is locked from the “Outlet” port by the upper shaft o-ring. The spring keeps the spool in the down or closed position. The valve is opened by manually pulling the palm knob outward, thus moving the shaft assembly upward. The detent pin is then pushed “In” to lock the relay open until a pneumatic signal is applied to the pilot cap of the relay. This pneumatic pressure acting on the piston causes the detent pin to drop “Out” of the locked position. When the relay is in the open position, it causes the middle o-ring to engage the body seal bore and the upper o-ring to disengage from the body seal bore respectively. Supply pressure at the “Inlet” port may then flow through the body to the “Outlet” port.When the pneumatic signal is removed from the pilot supply “PS”, the spring moves the shaft assembly downward. This causes the upper O-ring to disengage the body seal bore. This also allows the middle O-ring to engage the body seal bore and prevent flow into the “IN” port. With the supply pressure blocked, pressure will flow from the “OUT” port and exit through the “VENT” port. The relay may also be closed manually by pushing the palm knob inward.II. INSTALLATIONThe “MP-4” can be mounted either vertically, horizontally, panel mounted (with optional panel mount nut), or supported by piping from any of its ports. If it is supported by piping, care should be taken that the strength of the pipe fittings used is adequate to prevent the fitting from breaking off in the relay body should the relay be inadvertently struck.Proper pipe thread sealant should be used on any pipe fittings threaded into the relay ports. If stainless steel fittings are used, a sealant that will prevent galling is required. Supply gas or hydraulic fluid flowing through the relay should be free of large dirt particles. If compressed air is used, it does not have to be lubricated. If natural gas is used, it should contain as little condensate as possible. This will extend the life of the seals.If the relay is going to be installed in a location where the stem will be exposed to excessive paint, sand, drilling fluids, etc., the use of the optional stem protector is recommended. The stem protector does not affect the operation of the relay and will prevent the relay from jamming should the exposed portion of the shaft accumulate excessive trash or debris.III. DISASSEMBLY (REFER TO SPEC.SHEET 1901)Tools required are as follows:• 7/16” open end wrench or suitable adjustable wrench•1” open end wrench or suitable adjustable wrench•7/8” open end wrench or suitableadjustable wrench and flat bladescrew driver (for removal ofoptional stem protector)A.

阀门执行器手动使用说明

阀门执行器手动使用说明手轮机构与气动执行器配套使用，当气源信号出现故障，阀门无法开启、关闭，或固定在某一位置时，就必须通过手轮来完成。

1.阀门的开启方向，通常是逆时针表示打开，顺时针表示阀门关闭。

因此，开关阀门时要注意方向。

2.阀门上的手轮、手柄是按正常人力设计的，因此，在阀门使用上规定，不允许操作者借助杠杆和长扳手开启或关闭阀门。

3.当手轮全开后，应倒转少许，使螺纹之间严紧，以免松动损伤。

4.若手轮是做限位用的，应在预定位置，检修时可借助标尺和记号记住它们全开和全关位置，这样可以避免全开时顶撞死点。

5.阀门出厂时，不论气动执行器是正作用还是反作用，手轮都在开启状态，并都用锁母锁死，以免操作人员误操作把手轮关下去，阀门无法打开或达不到所需流量，造成不必要的事故和损失。

6.操作人员在用手轮操作前，先将手轮锁母松掉，再进行操作，操作完成后，如无特殊说明，一定要把手轮打开，并用锁母锁死。

MANUAL VALVES VS. AUTOMATIC FLOW LIMITING VALVESydronic system balancing is an important part of the HVAC industry. Without hydronic balancing, some coils in a system have too much flow and other coils don’t have enough flow; the building isn’t “balanced.” An unbalanced system can lead to excessive occupancy complaints as people are either too cold or too hot in the building.Many engineers focus on carefully selecting energy efficient boilers, chillers, and terminal units. However, without proper flow through these units, their efficiencies and heat transfer capabilities are altered. The problem is exacerbated as the pressures change in the building’s hydronic system, as changing pressures have a direct impact on flowrate. Q=Cv√∆P) While the industry accepts that pressure changes cause flow changes which then causes heat transfer changes, many engineers still accept manual balance valves because the INITIAL unit cost is less than automatic or pressure independent valves. But is initial cost all there is to consider? Automatic & Pressure Independent Valves -the cost effective option over Manual Balance ValvesThe procedure to manually balance a system is very labor intensive. The pressure drop across each valve is measured and a ball or plug is adjusted to bring the pressure drop to design pressure. Each time a valve in the system is adjusted, the flow through the other valves will change including those previously set because of the pressure change. Hence, the previously set valves must be reset, which in turn affects the flow through the other valves...and so on. In a large system, a minimum of three balances per valve is generally recommended by ASHRAE and NEBB.Contractor price for ¾” manual balance valve with memory stop: $35.Cost to balance three times total: 20-30 minutes @$125./hr: $42.00 to $62.50 On the other hand, each automatic flow limiting or pressure independent (PI) valve is self balancing as soon as the pump is turned on. The only labor required is for flow verification. The pressure drop across each valve is measured by using the ports provided on the valve body. As long as the PSID is within the control range listed on the valve tag, the flow, which is also listed on the tag, will be within plus/minus 5%.HContractor price for 3/4” automatic valve with isolation valve: $60.Cost to verify ﬂow: <5 min @ $125./hr: <$10.Manual = $77 to $97.5Automatic = <$70It is true the initial cost of a manual valve is less expensive than an automatic valve, but once labor to balance the valve is taken into consideration the total cost can be considerably more. More importantly, once the system is live and pressures start changing an automatic or PI valve will maintain the design flow in spite of system pressure changes. A manual valve will have an increase or decrease in flow as the pressure increases or decreases.Buy Fewer ValvesSystems utilizing automatic flow limiting or PI valves require far fewer balancing valves than systems that are manually balanced. Figure 1 shows a schematic of a system serving 18 heat transfer (heating or cooling) coils.Figure 1.The manual system, shown above, requires a total of 27 valves whereas the automatic system, on the right, requires only 18 because it does not require the “partner balancing valves” (shown in red) on the risers and the branches.As each terminal unit automatic flow limiting and pressure independent control valve isself-balancing over a wide differential pressure control range, the flow through the risers and the branches is also automatically controlled (balanced) without the use of additional valves.Using 18 valves instead of 27 manual valves is approximately 1/3 savings in initial product purchases. In our previous example that is 27*$77 to $97.5 or $2,079 to $2,632.50 in manual valve costs. In comparison the automatic system costs 18*$70 or $1,260 in valve costs which is a substantial savings.The elimination of the manual partner balancing valves on the mains, risers and branches in turn eliminates the head loss through them. Hence, the system head loss is reduced which lowers the pump head requirements.System Stays Balanced Even During Reduced Load ConditionsNo coil will starve when saving money by variable speed pumping. However, reducing the total water flow does not mean that all the coils in the building individually need the same reduction in flow. For example, on a typical spring day at 1:00 p.m., the total chilled water requirements of an8-story office building will generally be much less than on a hot summer (design) day. However, the air-handler serving the filled-to-capacity cafeteria, on the first floor, will require almost 100% (of design) chilled water. A building with automatic flow limiting or pressure independent valves will give you this diversity whereas one with manual balancing valves cannot.Figure 2.The schematic at the top shows the design load condition. The system operation point, at design load, is at (say) 125 feet of pump head. The head loss across the various elements (which adds up to 125 feet) for the cafeteria circuit, is as shown. Since the cafeteria is on the first floor, the head loss through the risers is negligible and is ignored.Please note, for design flow at design head, the head loss through the manual balancing valve is the same as that through an automatic flow control valve (86 feet).If this is a manually balanced building, as shown in Figure 3 on the left side, valve MBV #5 would have to be added and manually set. Howev-er, doing this would change the flows through existing valves MBV #1 through MBV #4 and they would also have to be reset. Similarly, upstream branch/riser balancing valves (not shown) may also have to be reset. The resulting labor cost can be significant.If this is a building with automatic flow control valves, as shown in Figure 3 on the right side, you would only have to add valve AFLV #4. Because these valves have wide control ranges, they would all automatically self balance to provide the required flows. No labor would be required to set the new valve or to reset any of the existing valves.Figure 3.The schematic in the middle shows what happens when system flow is reduced (by lowering the pump speed to 52%), if the system is manually balanced. At the lower speed, the pump head will be smaller as will all the pressure losses. Since nothing else has changed in the cafeteria coil circuit, the head loss through the various elements will decrease proportionately and now add up to 65 feet instead of 125. Since the head loss through the manual flow control valve is reduced to 44.7 feet and since flow is proportional to the square root of the head loss, the flow through the manual balancing valve (and the coil) is reduced to 72% (square root of 44.7/86). There is NOW a flow deficit of 28%.The schematic at the bottom shows what happens when system flow is reduced by the same amount if the system has automatic flow limiting valves. Again, the pump head decreases to 65 feet. However, the head loss distribution is not proportional. Instead, the cartridge inside the automatic flow control valve moves by a precise amount, to absorb only 26 feet of head and keeps the flow at the required 100%.With the automatic flow limiting or pressure independent valve, there is no flow deficit at reduced system flow and reduced pump head.(Note: In all three schematics of Figure 2, all losses in the pump room are ignored for clarity of discussion.)Building Renovation Does Not Require Hydronic System Rebalance Very often, space renovation in an existing building also changes the heating/cooling requirements of that space. For example, an open office area that is converted into a large conference room will require more cooling due to the additional sensible and latent heat from the people. This may result in an additional fan-coil unit for the conference room. Figure 3 illustrates this scenario for a Manual vs. Automatic system.Griswold Controls designed the first balance valve in the market in 1960, years before the first manual balance valve was designed and manufactured. The all stainless steel flow limiting cartridge is a standard in the industry because of its simply elegant design. Above its control range (blue colored area in Figure 4), the cup will move all the way in, exposing the minimum orifice area. In both cases, the cartridge will now act as a fixed orifice device, varying flow based on the out-of-range differential pressure.You do not have to worry about the cartridge ever shutting off the flow completely because a minimum orifice area is always open.C U P P A R T I A L L Y O U TCU P F UL L Y I N C U P F U L L Y O U T Below the control range, the cartridge acts as a variable flow device, allowing flow to vary below the rated amount.Above the control range, the cartridge acts as a variable control device, allowing flow to vary above the rated amount.Within the wide control range, the cartridge modulates in response to pressure differential changes to maintain a fixed flow rate within ±5% accuracy.

手压阀的说明书

手压阀的说明书
手压阀主要包括调节螺母、胶垫、阀体、弹簧、阀杆、锁紧螺母、销钉、手柄、球头和填料。

其中阀杆的锥面制造和阀体的锥面配合起密封作用，故这两个零件的最为重要。

手压阀工作原理是：电磁脉冲阀由电磁先导头、膜片和阀上海华宇物流体组成，膜片后腔的面积大于前腔的面积，气压作用力大，使膜片处在关闭位置，电控仪输入电信号，使电磁先导头吸合动柱，打开卸荷孔，膜片后腔的压力气体迅速排出，膜片前腔的压力气体将膜片抬起，打开脉冲阀通道进行喷吹，电信号消失，电磁先导头的弹簧使动柱签证立即复位封闭卸荷孔，膜片后腔气体压力和弹簧作用力使膜片关闭通道，阀停止喷吹，膜片上的阻尼孔，当先导头动柱抬起，气体压力卸荷时，起到阻加拿大投资移民尼气流的作用，当卸荷封闭时，使压力气体迅速充满到后腔，使膜片关闭通道，停止喷吹。
