If the pipe inside the foreign body, impurities, it may lead to self-reliance type pressure regulating pneumatic valve is blocked.
In the face of such problems, what should we do?
To introduce the below six can be a solution to this situation.
1, the cleaning method: pipes welding slag, rust, slag, etc. May be blocked or clogged pneumatic valve cover, under the guide part and balance hole orifice, thus producing strain on the surface, and scrape the pneumatic valve core and guide surface. In this case, it must be cleared for clean, slag, if the sealing surface is damaged, should be grinding; At the same time, open the bottom plug, washed away from balance hole into the pneumatic valve cover slag and flushing of the pipe. Please fully open before debugging self-reliance type pressure pneumatic valve adjustment. After a period of time, the media will enter a state of normal operation.
2, medium irrigation: the use of the medium itself flushing, energy, and wash away easy precipitation, easy blocking, so as to improve the resistance of the pneumatic valve block function. Common methods include:
a. To flow closed type;
b. With streamlined pneumatic valve;
c. Place the throttle scrubbing in bad place. When using this method, attention should be paid to improve the corrosion resistance of throttle.
3, straight Angle method: direct S flow, the flow is complex, the inferior vena room more dead zone, provides the secondary precipitation. Medium such as the elbow Angle connection to run through 90 ° C, washing performance is good, dead zone is small, easy to design into a streamline.
4, increase the throttle clearance methods: as a result of the action of pneumatic valve throttle, medium solid particles or slag, rust, etc will not be throttling congestion or blockage, you can use the throttle gap big part. Flow components - Throttle area is a window, open a pneumatic valve core and a bushing. Together with throttling area rather than in weeks up distribution, so easy to eliminate the fault. For single or two-seat pneumatic valve, plunger can be slippery pneumatic valve changed to 'V' slippery pneumatic valve, pneumatic valve can change it to the sleeve.
5, external cleaning method: when some easy precipitation and medium containing solid particles through self-reliance type pressure regulating pneumatic valve, usually at the throttle and the guide was blocked, and can wash in the bottom of the lower gas and steam hood. When adjusting the pneumatic valve is blocked or blocked, can open the external gas or steam pneumatic valve to complete the washing operation, without the need for mobile pneumatic valve in order to make the normal work of the pneumatic valve adjustment.
6, pipeline filter installation method: for small diameter self-reliance type pressure regulating pneumatic valve, especially super small flow control, pneumatic valve, pneumatic valve throttle clearance is small, less slag, even medium will also be blocked, the filter is installed in the pneumatic valve before the piping. Ensure the smooth through the medium. When using the locator using regulator, locators cannot work normally, the pneumatic throttle is usually considered a fault.
