Therefore, flange and pipe installation should be vertical and accurate position to avoid pipe deformation. (3) Control valves are precision components that, if they are stressed by pipe deformation, will disrupt normal operation. Change the flow direction to improve life Open flow toward the open direction, cavitation, erosion mainly on the sealing surface, so that the valve core and valve seat sealing surface quickly suffered damage; flow closed toward the closure of the direction of flow , Cavitation erosion role in the throttle after the valve seat sealing surface to protect the sealing surface and the valve root, extending the life. Increase the throttling channel to increase life-span method to increase the throttle channel The simplest is to thicken the valve seat, the valve seat hole growth, the formation of a longer throttling channel. 7. In this way, cavitation, erosion and other damage occurred in the spool head. As an overhaul of a chemical plant will be djl parts dgl0 replacement, life expectancy increased by 1 times. As our new product,PIPE Bracket is popular in the market, especially makes an important role in city construction. 4. S to increase the work to increase the opening to increase the life of the valve orifice plate throttling consumption pressure drop; close the pipe on the manual valve in series to the control valve to obtain a more satisfactory opening so far. (4) The control valve must be especially careful when welding with the pipe. Transfer damage position to improve life expectancy to the place of serious damage to the secondary location to protect the valve seat sealing surface and throttle face., LTD is a professional manufacturer and exporter that is concerned with the design, development and production of power equipment . If the control valve and pipe welding attention is not enough, failed
drive pulley manufacturers to eliminate the stress, it will have deformation. 3. Our well-equipped facilities and excellent quality control throughout all stages of production enables us to guarantee total customer satisfaction. All of our products comply with international quality standards and are greatly appreciated in a variety of different markets throughout the world.5. With the destruction of the valve, the flow increases, the corresponding valve and then off, so constantly damaged, and gradually closed, so that the entire valve fully take full advantage of the same time, a large opening of the work flow gap, erosion erosion weaker than the beginning Let the valve in the middle of the opening and a small opening on the work to improve life expectancy of 1 to 5 times. (5) When the pipe is under pressure test and blow-off, the control valve should be removed and connected with the corresponding straight pipe section to prevent the debris such as welding slag and iron cutting from getting stuck between the valve core and the valve seat....
