Wilden Air Valve is a special valve used to prevent negative pressure in the pipe caused by the decompression wave in the transient process. It is usually installed at a high point where the dynamic water pressure is low when the pipeline is in normal operation, and the liquid column separation may occur during the transient flow process. Wilden Air Valve is a respirator for pipelines and a safeguard for pipeline

The low-pressure stage suction valve and exhaust valve of the air valve assembly are mounted on the cylinder head and have a lift of 3mm. The high-pressure stage suction valve and exhaust valve are installed in the valve chamber in the middle of the cylinder. The cylinder and the piston are divided into two sections with a large diameter and a small diameter. Above the top of the piston is the low-pressure stage work

From the working principle of the air valve assembly, the working performance of the air valve assembly will directly affect the work of the compressor cylinder. Therefore, the air valve assembly has the following requirements: (1) Small resistance loss The size of the valve resistance loss is related to the valve gap speed of the airflow and the size of the spring force. The higher the gas velocity, the greater

The air valve assembly is an important part in the reciprocating piston compressor, and it is also one of the easily damaged parts. Its quality directly affects the displacement, power consumption and reliability of the compressor. When the compressor is developing towards a high speed, one of the key issues limiting the speed increase is the valve assembly. The air valve assembly is the component in the compresso

(1) The energy used is different Pneumatic components and devices can adopt the method of centralized air supply in the air compressor station, and adjust the working pressure of their respective pressure reducing valves according to different use requirements and control points. Hydraulic valves are equipped with oil return lines to facilitate the collection of used hydraulic oil in the oil tank. The pneumatic

Pneumatic control valve refers to various pneumatic components that control the pressure, flow and flow direction of air flow in the pneumatic system and ensure the normal operation of pneumatic actuators or mechanisms. The element that controls and regulates the pressure of compressed air is called a pressure control valve. The element that controls and regulates the flow of compressed air is called a flow contr

Pneumatic valves are valves driven by compressed air. When purchasing pneumatic valves, it is only necessary to specify the specifications, types, and working pressures to meet the purchasing requirements. flow. It is not perfect in the current market economy environment. Because the pneumatic valve manufacturers have carried out different innovations under the concept of unified design of pneumatic valves for prod
