Rubber wedge gate valve For sale tells: the relevant knowledge of wedge gate valve
The wedge gate valve achieves the sealing effect by forming a sealing pair between the two sealing surfaces on the wedge gate and the sealing surfaces of the two navigation grooves on the valve body. Its structure is simple, and the fluid is small, and it is often used for long-distance transportation, pipelines and devices for water, oil, gas and other media. Let's follow the editor of rubber wedge gate valve For sale for a simple understanding!
The purpose of using the wedge gate is to increase the auxiliary sealing load, so that the metal-sealed wedge gate valve can seal both high medium pressure and low medium pressure. When closing, rotate the valve stem clockwise to make the sealing surface of the gate valve and the sealing surface of the valve body close to achieve a seal. However, the metal-sealed wedge-type gate valve produced by the wedging action is often not enough to achieve the inlet-side seal due to the specific pressure of the inlet end of the wedge.
Wedge gate valves are generally used in occasions where there is no strict requirement on the external dimensions of the valve, and the use conditions are more demanding. Such as the working medium of high temperature and high pressure, it is required that the closing parts must be sealed for a long time. Generally, the use conditions or require reliable sealing performance, high pressure, high pressure cut-off (large pressure difference), low pressure cut-off (small pressure difference), low noise, cavitation and vaporization, high temperature medium, low temperature (cryogenic), it is recommended to use Wedge gate valve. Such as the electric power industry, petroleum refining, petrochemical industry, offshore oil, water supply engineering and sewage treatment engineering in urban construction, chemical industry and other fields.
The above is the editor of rubber wedge gate valve For sale: a brief introduction to the relevant knowledge of wedge gate valve.
