泄压阀作业指导书

泄压阀作业指导书
1、泄压阀结构：
首站使用的泄压阀是先导式泄压阀，它主要分为阀体部分、阀前和阀后部分。

阀前部分又包括球阀、压力表、平衡管和导阀。

2、泄压阀各部分功能：
压力表：显示阀前管线压力。

平衡管：将阀前压力引至阀腔内，用于阀芯平衡。

导阀：导阀上有调整螺丝，通过调整螺丝可以设置泄放压力。

3、泄压阀工作原理：
首站泄压阀的设计压力是10.6MP a，当阀前压力低于设计压力时，导阀关闭，泄压阀前后压力平衡；阀前压力高于设计压力时，导阀开启，通过平衡管先将一小部分油品泄放至阀后管道，所以阀腔压力降低，前端压力推动阀芯后移，使油品大量泄放。

图一结构示意图1、闸阀2、过滤器3、先导阀4、压力表五、工作原理安全泄压阀是通过进口压力的变化，反馈到导阀上，再由导阀来控制主阀板的启闭，使管路中的压力能保持安全稳定的状态，一旦超压，能及时泄压。

当管路中的压力超过先导阀的设定值时，进口压力水从控制管进入先导阀膜片下腔内，使其压力增高，推动先导阀阀杆上移，先导阀阀板打开，主阀控制室上腔的水从先导阀和控制管排泄，在进口压力水的作用下，主阀板打开。

当管路中的压力下降至低于设定值时，先导阀膜片下腔的压力降低，先导阀阀杆下移，使其阀板关闭。

从而导致从控制管进入先导阀再到主阀控制室上腔的压力水的压力增高，在上腔水压作用下主阀板关闭。

六、安装注意事项1、安装前，先检查阀各部件是否完好，紧固件、附管件联接是否牢固、可靠。

这确保了在吸入行程时不会有流体由于惯性或虹吸作用流入排出管路。

这些阀在泵运行时还可作为防虹吸阀。

二、特点1、高可靠性/低成本2、PTFE/EPDM复合膜片3、泄压阀0～1.0Mpa可调背压阀0～0.3Mpa可调4、可安全释放排泄至吸入管路或溶液箱中5、背压阀具有防虹吸功能6、防松调节螺钉7、机加工结构，坚固三、工作原理VS系列隔膜式泄压阀在正常情况下，泄压阀不泄放，内部弹簧压紧支承块，使隔膜顶住阀座将排放口密封，当系统压力高于阀门设定压力时，化学品流出并回流至化学容器或计量泵吸入管路（在现场可通过调节螺钉在0～1.0Mpa范围内设置压力，泄放压力应设置高于系统压力约0.1Mpa。

建议在管线上安装压力表以便现场调整泄放压力）。

膜片保持顶启，直到系统压力再次下降到阀门设定压力以下，弹簧将隔膜压下封住排放口，继续正常的运行。

VB系列隔膜式背压阀通过抵消吸入惯性和防止工艺压力低于吸入压力时的系统虹吸，消除由投加点压力波动引起的投加量变化，在计量泵排出端保持一定的压力以确保精确计量。

（在现场可通过调节螺钉在0～0.3Mpa范围内设置背压）。

在计量泵的排出行程压力作用于隔膜，将其顶启，而使计量泵的液体通过。

当计量泵的排出流量减少至0时（吸入行程），弹簧使隔膜复位，将计量泵出口和阀门之间的低压液体分开，这样就保证了泵出口止回阀恒定的正压。

外接能源式（氮气式）泄压阀安装和维护手册External Energy (Nitrogen-Controlled) Relief ValveInstallation and Maintenance Manual重庆科特工业阀门有限公司Chongqing Kete Industrial Valve Co., Ltd.一、产品结构及工作原理I. Structure and Working Principles1、产品结构：如图11. Structure, as shown in Fig. 1阀座valve seat滑塞腔 Plug chamber滑塞 PlugFig. 12、工作原理：2. Working Principles:外接能源式（氮气式）泄压阀的工作主要依赖于对泄压阀滑塞内腔的压力控制，其滑塞内腔控制动力由外供氮气瓶通过氮气控制柜减压系统对其控制压力进行调控。

The External Energy (Nitrogen-Controlled) Relief Valve works mainly depending on the pressure control to its inner plug chamber. The control force to the inner plug chamber is supplied from external nitrogen bottle, with its pressure regulated by a reducing system in the nitrogen distribution cabinet.当输送管线正常工作时，滑塞在内腔设定压力作用下将滑塞紧紧的与主阀座贴合，使泄压阀处于正常关闭状态；当管线发生水击，异常升压，超过其滑塞内腔所设定的安全控制压力时，在压差的作用下滑塞打开，通过滑塞外腔开始泄压并报警，管线压力下降，当管线压力恢复正常工作压力时，滑塞与阀座紧紧贴合，恢复关闭状态，停止泄放。

Forge Motorsport 2.0T FSI Replacement Bypass Valve KitPlease thoroughly read through and familiarize yourself with these instructions prior to beginning the installation process of any component. Please also ensure that the vehicle and engine have cooled down sufficiently to avoid risking skin burns or other injury.Tools Required:- Vehicle jack and jack stands or access to a vehicle lift- 5mm Allen wrench or Allen socket with extension- 3mm Allen wrench- 1/8 Inch Allen Wrench- Razor blade or Xacto knife to cut vacuum line- Blue colored medium strength semi-permanent Loc-Tite thread lockerBegin by safely lifting the vehicle and then locating the turbo and the OEM electronically controlled bypass valve/solenoid, which will be bolted to the compressor cover of the turbo.- On the MK5 VW GTI and Jetta GLI, the B6 Passat, and the 8P Audi A3, the OEM valve will be bolted to the turbo located on the lower passenger side of the rear of the motor.- On the Golf ED30 and R, Leon Cupra, Scirocco R and Audi S3 the valve is located at the top of the engine bay at the front directly behind the radiator- On the B7 Audi A4, the OEM valve will be bolted to the turbo located on the passenger side of the motor towards the front underside of the carOnce located, disconnect the electrical connector/plug for the valve and you can now use your5mm Allen wrench or socket to remove the three 5mm Allen bolts which secure the valve to the turbo. You must be sure to save the OEM valve bolts as they will be reused later.With the OEM valve removed from the turbo, you can now temporarily install the Forge replacement valve reusing the OEM bolts with them only hand-tightened. This initial installation is only temporary so as to find an appropriate mounting location for the solenoid and to find the appropriate lengths for the vacuum lines you will use on your car.First, attach the solenoid to your choice of the supplied brackets using the two supplied 5mm Allen bolts. The solenoid can be mounted anywhere in the engine bay within reach of the solenoid wiring.For the purpose of generating these instructions, we will mount the solenoid bracket using one of the bolt holes for the new Forge valve as shown below. You do not have to install the solenoid bracket in this manner on your application if you would prefer a different location.With the new Forge valve loosely mounted to the turbo, and a location selected for the solenoid and it loosely mounted as well, measure to find appropriate lengths for the vacuum hose connections between the valve and the solenoid.Please use the plumbing diagram below for the appropriate locations to connect the vacuum lines. As stipulated in the plumbing diagram, the plumbing MUST be as shown or the valve may fail to operate properly or possibly at all.Once you have determined the length of vacuum line you will need between each connection of the valve and the res pective connection on the solenoid, you can cut the appropriate lengths of line from the included s pool. The lengths you cut and use will be based on where in the engine bay you have chosen to mount the solenoid.You can now remove everything from the car to secure the lines between the valve and solenoid as shown above.With the valve and solenoid plumbed together and the lines secured with the included zip ties, you can now permanently mount the valve and solenoid bracket.Use your 5mm Allen wrench to bolt the new Forge valve to the turbo from where the OEM valve was removed, again, reusing the OEM valve bolts.Securely clip the supplied wiring harness to the solenoid (it is a tight fit) before you mount the solenoid in the engine bayWith the valve securely mounted to the turbo and the solenoid bracket also secured at your desired location within the engine bay, you can reconnect the OEM wiring harness plug to the connection on the end of the Forge wiring harness.We will now move on to the vacuum tap piece which will need to be connected to the intake manifold. The vacuum tap has 3 tap provisions and is supplied with multiple vacuum nipples and blanking plugs for you to select the number of provisions you will need on your application.- One nipple must be used at a minimum for valve operation. (largest port nipple only)- A second nipple can be used for a boost gauge tap. (s mallest port nipple only)- A third provision is available and can be used for whatever it may be needed for on your application.- All unused port provisions must be plugged with the supplied port plugs. (3mm Allen)It is highly recommended that all vacuum nipples and port plugs are secured with blue colored, medium strength, semi-permanent Loc-Tite thread locker. If not used, the vacuum nipples and port plugs may back out, becoming lost and/or causing a vacuum/boost leak.To install the vacuum tap, you will need to unclip the PCV hose connection on the intake manifold. This can be found up and to the right of the throttle body while looking at the manifold. Pinch down on the two ribbed sections releasing the clips and pull the hose out of the manifold barb.Next, you will slide the manifold tap over the barb until the edge of the lip can no longer be seen through the grooves in the tap. Once the lip is no longer visible, insert the black plastic C-clip to secure the tap in place. The o-ring seals are very tight and secure, so this may take a small bit of effort.Once the manifold tap is held securely in place with the plastic C-clip, reattach the PCV hose to the barb at the end of the tap.If you are using some sort of PCV “fix” or “bypass”, h owever, you will need to reconnect whatever components are supplied with that product. The barb on the end of our manifold tap is the same size and shape as the OEM manifold barb, so any hoses or caps that connect to the manifold barb will connect to the barb on our tap as well.From the appropriate nipple on the manifold tap (largest port), run a length of vacuum tubing along the top of the motor, around the passenger side, following the fuel rail and fuel lines, down to the remaining linear port on the solenoid you mounted previously. (See plumbing diagram) Secure both ends of this line using two of the included zip ties. If any s pare zip ties are available, use them to secure this vacuum line to the fuel rail and/or fuel lines.Your valve installation is now complete, and you can now enjoy all of the benefits that a more reliable and performance orientated bypass valve has to offer. You should notice slightly quicker spool, less tapering, more responsive mid-range, and overall better valve and boost response.打造赛车 2.0T FSI 置换旁路阀工具包请彻底阅读并熟悉这些指令之前，在开始任何组件的安装过程。

2.2 持压泄压阀的工作原理持压泄压阀是一种用来保护管道系统和设备免受过压危害的关键装置。

其工作原理主要基于压力传感器和控制阀的协同作用。

当管道系统内部的压力超过设定值时，压力传感器会检测到这种异常情况，并传递给控制阀。

控制阀会根据传感器的信号，打开或关闭阀门，调节介质流动的速度和压力，以确保管道系统的压力处于安全范围内。

持压泄压阀的工作原理可以简单理解为一个动态平衡的过程。

当管道系统的压力超过设定值时，控制阀会打开，释放部分介质，降低管道系统的压力；相反，当压力低于设定值时，控制阀会关闭，保持介质的流动速度，维持管道系统的压力稳定。
