Structural characteristics and uses of pneumatic gate valve_Characteristics Answers

Author:


There are many gate valves in our lives. The pneumatic gate valve is a door with a right-angle swing structure design. This kind of valve is generally installed and used with a positioner, mainly to achieve a certain proportion of adjustment and has a good adjustment effect. Pneumatic gate valves can be installed in various situations that require adjustment. They are better adjusted and sealed than super large valves. What are the uses of pneumatic gate valves? What are the characteristics of pneumatic gate valves? Now let's take a look at the usage characteristics of pneumatic gate valves.

Pneumatic gate valves can be installed in various situations that require adjustment. They are better adjusted and sealed than super large valves. What are the uses of pneumatic gate valves? What are the characteristics of pneumatic gate valves? Now let's take a look at the usage characteristics of pneumatic gate valves.

  The purpose of pneumatic gate valve

  It is a right-angle rotating structure. It is used in conjunction with the valve positioner to achieve proportional adjustment. The V-shaped valve core is most suitable for various adjustment occasions. It has a large rated flow coefficient, a large adjustable ratio, a good sealing effect, and zero sensitivity in adjustable performance. , small size, can be installed up and down. Suitable for the control of gas, steam, liquid and other media.

  Characteristics of pneumatic gate valve

  It is a right-angle rotating structure, consisting of a V-shaped valve body, a pneumatic actuator, a positioner and other accessories. The ratio of natural flow characteristics is roughly equal; double bearing structure, small starting torque, high sensitivity, fast sensing speed; super shear resistance.

 

  The pneumatic piston actuator uses compressed air as the power source and drives the arm to rotate 90 degrees through the moving piston to automatically open and close the valve. Its components include: adjusting bolt, actuator box, crank arm, cylinder block, cylinder shaft, piston, connecting rod, and universal shaft.

  Working principle of pneumatic gate valve: Pneumatic control valve is composed of actuator and regulator. The driving mechanism is the thrust element of the regulating valve. It generates corresponding thrust according to the pressure of the control signal to promote the action of the regulating mechanism. The valve body is the regulating part of the pneumatic regulating valve, which is in direct contact with the regulating medium and regulates the flow of fluid.

  Principle of pneumatic gate valve

  Pneumatic gate valve is a valve driven by compressed air. When the gate valve is closed, the sealing surface can only rely on the medium pressure for sealing, that is, the sealing surface relies on the medium-pressure pressure of the seat on the other side of the door to ensure the sealing surface, which is automatically sealed. . Most gate valves are forced-sealed, that is, when the valve is closed, external force is required to force the gate valve into the valve seat to ensure that the sealing surface is sealed.

  Do you know the uses and characteristics of pneumatic gate valves? Pneumatic gate valves are mainly used to control the transmission media of gas and liquid, and can be used to control the flow of liquid gas. Pneumatic gate valve adopts piston control, which mainly uses gas as the driving force. It can open and close the valve by compressing the gas. Pneumatic gate valves need to rely on external force, because air pressure is an external force and cannot work without external force. In addition, when installing pneumatic gate valves, attention should be paid to the stability of air pressure.
