What is the structural difference between electric gate valve and globe valve? Which one is better?

The sealing surface of the electric gate valve has a certain self-sealing ability. The valve core is in close contact with the valve seat sealing surface through the medium pressure to prevent leakage. The inclination angle of the wedge-shaped valve core is generally 3-6 degrees. When forced to close, the temperature of the valve core changes too much or is too large, and it is easy to get clogged. Therefore, some measures must be taken in the structure of high-temperature and high-pressure wedge valves to prevent the valve core from getting stuck. When opening and closing the electric gate valve , the valve core and valve seat sealing surfaces are always in contact and friction with each other, so the sealing surface is easy to wear, especially when the valve is closed, the pressure difference between the front and rear valve cores, and the sealing surface wear is more serious.

Valve pressure bearing direction instructions and installation direction requirements

As the name suggests, the pressure bearing of a valve refers to the pressure that the valve can withstand, that is, the pressure level of the valve is not lower than the design pressure level of the pipeline. The pressure-bearing direction refers to the closed state of the valve after it is used in pipeline conditions. The arrow direction of the valve body is the direction recommended to withstand pressure. If installed incorrectly, leakage failure may occur due to lax closing of the valve. Generally, it is determined based on the process flow or usage conditions. The same direction refers to the pressure-bearing direction (the side with high medium pressure on both sides of the valve gate) and the flow direction. The opposite direction refers to the pressure-bearing direction (both sides of the valve gate). The side with high medium pressure) is opposite to the flow direction of the medium.

There are "cool tips" to deal with several leakage problems of stainless steel gate valves

Although the selection of stainless steel gate valves depends on the quality of the ground, what is invariable is that the first is the working nature, the second is the setting position, then the span of the operating stainless steel gate valve hole, and the opening and closing force, and then the project cost. , these reference factors should also be combined with the characteristics of stainless steel gate valves and existing operational experience, and determined through technical and economic comparison.

The working principle of pneumatic gate valve: How is it different from the principle of pneumatic actuator - Answered

The working principle of the pneumatic gate valve . The two-position five-way solenoid valve of the pneumatic gate valve is equipped with a double-acting pneumatic actuator. It uses compressed air to drive the actuator and combines the movement of multiple groups of pneumatic pistons to drive the main shaft to rotate. Each cylinder plate compresses the air gas and changes the The position changes the main shaft's gas, the rotation direction force beam and the curve tracking characteristics, the rotation torque is required according to the requirements of the load (valve), the number of adjustable cylinder combinations, and the driving workload (valve).

What are the different functions of electric gate valves according to their structural forms? Answered

The switch action position of the electric gate valve may be intermediate disassembly, the movement of the teeth is easy, and easy to protect, because the early body process is buffered with silver, and it is not easy to get stuck and damaged, but there must be a source of fire, and it is also more complicated than the control of the electric valve. . This type of valve should be installed in the water pipe as usual.

What is an electric valve? How much does it cost? Answered

Electric valves are usually connected to the valve by an electric actuator and become an electric valve after installation and commissioning. The electric valve is powered by electric energy and is connected to an electric actuator to drive the valve to realize valve switching and adjustment actions. In order to achieve the purpose of switching or adjusting the pipeline medium.
