Valves are control components in fluid conveying systems that have functions such as cutoff, regulation, diversion, prevention of reverse flow, pressure stabilization, diversion, or overflow pressure relief. According to different classification standards, there are various types of valves, and each valve has its own unique features. 1. By valve type Block valve: Block valve, also known as closed ...

(1) Wedge type single gate valve ① The structure is simpler than that of an elastic gate valve; ② At higher temperatures, the sealing performance is not as good as elastic gate valves or double gate valves; ③ Suitable for high-temperature media prone to coking. (2) Elastic gate valve It is a special form of wedge type single gate. Compared with wedge gate valves, they have good sealing performance...

The purpose of using a check valve is to prevent reverse flow of the medium, and a check valve is generally installed at the outlet of the pump. In addition, a check valve should also be installed at the outlet of the compressor. In short, in order to prevent reverse flow of the medium, check valves should be installed on equipment, devices, or pipelines. Generally, vertical lift check valves are ...

Steam trap is an automatic valve used in steam heating equipment, steam transmission pipelines, and steam usage devices. Quickly discharge the condensed water generated by steam work from the device, prevent fresh steam leakage, and maintain the efficiency of the device at its optimal state. No form or type of steam trap is omnipotent. In order to select and install the ideal steam trap, considera...

Ball valve structure There are many types of structures for ball valves, but they are basically the same. They are all round ball cores with opening and closing parts, mainly composed of valve seats, balls, sealing rings, valve stems, and other driving devices. The valve can be opened and closed by rotating the valve stem 90 degrees. They are used in pipelines to shut off, distribute, regulate flo...

1. Structural differences When selecting models with limited installation space, attention should be paid to: The gate valve can rely on the medium pressure to tightly close the sealing surface, thus achieving the effect of no leakage. When opening and closing, the sealing surface of the valve core and valve seat always contacts and rubs against each other, making the sealing surface easy to wear....

Adjustment of safety valve opening pressure (set pressure): Within the specified working pressure range, the opening pressure can be adjusted by rotating the adjusting screw and changing the pre compression amount of the spring. After removing the valve cover and loosening the locking nut, the adjustment screw can be adjusted. Firstly, increase the inlet pressure to make the valve jump once. If th...
