The correct selection of valve accessories is of great significance for the reliable and stable operation of pneumatic valves. The control loop of the valve is composed of each accessory. Improper selection or failure of valve accessories can lead to abnormal or refusal of valve operation, posing a huge safety hazard to the process. The compressed air output from the air compressor contains a larg...
(1) The installation position of the regulating valve should meet the requirements of the process flow design, and should be close to the primary indicating instrument related to it, so that the primary instrument can be observed when manually operating the bypass valve; (2) The regulating valve should be arranged on the ground or platform and easy to operate and maintain; (3) The regulating valve...
Metal materials require not only sufficient strength and plasticity, but also sufficient toughness during use. Toughness is the ability of a metal to absorb deformation energy before fracture. The toughness of metals usually decreases with increasing loading speed, decreasing temperature, and increasing stress concentration. Toughness is a mechanical performance indicator that measures the sensiti...
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...
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...
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...
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...
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...
