The processing method of regulating valve

    Processing method

    Cleaning method

     Pipe welding slag, rust, sediment and so on in the throttle,steering parts, lower balance valve cover holes caused by blocked or stuck to the spool surface, surface oriented productionstrain and scratches, sealing surface indentation. This often happens in the new operation system and put into operation after the initial repair. This is the most common faults. In such cases,must be opened for unloading clean, except dregs, such as a sealing surface damage should be grinding; at the same time,open the bottom plug, to flush from the balance under the valve cover hole fall into the slag material, and pipe for flushing. Before operation, to adjust valve fully open, then the media flow into the normal operation after a period of time.

    External flushing method

    For some easy to precipitate, solid particles of the medium containing the common valve adjustment, often plugged in the throttle, the guide, the erosion of gas the end of the next valve cover plug and vapor. Generated when the valve is blocked or stuck, open the external gas or steam valve, control valve can be fixed in the case of washing work done, so that normal operation of the valve.

    Installation of pipe filter method

    Control valve on the small caliber, especially in ultra small flow control valve, the throttle gap especially small, medium can not have a little bit of residue. In this case the plug, best to install thepipe in the valve before a filter, to ensure smooth through the medium. Regulating valve used with locator, locator is not working properly, the gas orifice plug is the most common faults.Therefore, when working with a locator, you must handle the gas source, usually by the way is to install the air filter relief pressure valve locator before the gas supply pipeline.

     Increase the throttle gap method

    Such as the medium of solid particles were washed out or pipewelding slag and rust caused by jam, jam fault for not throttle, can use larger throttle throttle clearance - saving an area of open window, open class spool, sleeve, because of its cutting areaconcentrated instead of circular distribution, the fault can easily be excluded. If you are single, two seat shaped piston spool valve can be changed to "core V" shaped mouth, or into the sleeve valve. For example, a chemical plant often have a stuck valve seat, recommended to use the sleeve valve, the problem is resolved immediately.

Basic Rubber Tensioner

     Medium scouring method

     Media's own energy use scouring, erosion and sedimentation away easily, easy to plug things, to improve the attempts to prevent the valve function.

     A common method of:

    The closed type flow using;

    The streamlined body;

    The orifice in the most severe erosion, using this method should pay attention to improving throttling material erosion resistance.

      Through to angular method.
