1.Gate valve refers to a valve that moves the closing element (gate) vertically along the axis of the channel. It is mainly used to cut off the medium in the pipeline, that is, fully open or fully closed. Generally, gate valves cannot be used to regulate flow. It can be suitable for low temperature and high pressure as well as high temperature and high pressure, and can be made of different materi...
Explosion proof solenoid valve is a device that encloses all components that may ignite explosive gas mixtures in a single enclosure. The enclosure can withstand the internal explosion of combustible mixtures that penetrate through any joint surface or structural gap of the enclosure without damage, and will not cause the ignition of an explosive environment formed by one or more gases or vapors o...
Selection and setting location of valves 1. Valves used on water supply pipelines are generally selected according to the following principles （1）When the pipe diameter is not greater than 50mm, globe valves should be used, and gate valves and butterfly valves should be used when the pipe diameter is greater than 50mm. （2）When adjusting flow and water pressure, it is advisable to use regulating va...
The regulating valve locator is the main accessory of pneumatic actuators, which is used in conjunction with pneumatic actuators to improve the position accuracy of the valve, overcome the influence of stem friction and medium imbalance force, and ensure that the valve is correctly positioned according to the signal from the regulator. In the following situations, a locator is required: 1. When th...
1、 Working principle of check valve Check valve refers to a valve that automatically opens and closes the valve disc by relying on the flow of the medium itself to prevent medium backflow. It is also known as a check valve, one-way valve, backflow valve, and backpressure valve. Check valve is an automatic valve that mainly functions to prevent medium backflow, prevent pump and drive motor reversal...
Pneumatic ball valve is composed of two parts: a cylinder and a ball valve. The cylinder serves as the driving element, and the output shaft provides power to drive the ball core of the ball valve to rotate, achieving functions such as pipeline switching, adjustment, and flow direction switching. For example, pneumatic O-shaped cut-off ball valve, pneumatic V-shaped regulating ball valve, pneumati...
Pneumatic valves mainly refer to valves that are activated by cylinders to form a power source through compressed air, thereby achieving the purpose of regulating switches. When the regulating pipeline receives control signals generated from the automation control system, it will adjust relevant parameters (such as temperature, flow rate, pressure, etc.). Pneumatic valves are mainly composed of th...
1、 What is a steam trap valve? A steam trap is a device designed on devices that require steam, which can automatically discharge condensate, air, and non condensable gases from the steam system and prevent steam from being discharged. 2、 The important functions of steam traps: (1) Able to quickly eliminate the generated condensate water; (2) Prevent steam leakage; (3) Remo...
The important component for adjusting pressure in a piston type pressure reducing valve is the piston plug. The pressure inside the pipeline is balanced by the size of the opening and closing ports of the piston plug. If the pressure in front of the valve is unstable, there may be fluctuations in the pressure behind the valve. Therefore, the pressure adjustment should be combined with the fluctuat...
