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...

In addition to sufficient strength and plasticity, metal materials also require sufficient toughness during use. Toughness is the ability of a metal to absorb deformation energy before fracture. The toughness of a metal usually decreases with increasing loading speed, decreasing temperature, and increasing stress concentration. Toughness is a mechanical performance indicator that measures the sens...

Drain, block steam, and exhaust air, therefore, in steam systems, drain valves are very important as they can maximize the utilization of heat energy and are the most important link between steam and condensate systems. 1. The essence of steam is water, which is a gaseous water containing a lot of heat. In the production process of using steam, when steam passes through heat exchange equipment, th...

1. Megapascals (MPa) is a unit of pressure, also known as megapascals. 1Pa refers to the pressure generated by a force of 1N uniformly pressing on an area of 1 square meter. 1 megapascal=1000000 Pa, which can also be written as 1MPa=1000000 Pa. 2. One kilogram of pressure (usually referring to force) refers to the situation where one kilogram of force is applied on an area of one square meter. The...
