Principle Analysis of Marine Pneumatic Quick Closing Valve
Marine pneumatic quick closing valve is a Marine valve controlled by air pressure, which is used to quickly close or open the flow of gas or liquid on the pipeline. Pneumatic quick closing valve is widely used in the field of ships because of its compact structure, simple operation, high reliability, and high pressure and temperature. Pneumatic quick closing valves are often used in boilers, steam powered machinery, oil pumps and pipeline devices.
Overview
Function and Application Scenarios
Marine pneumatic quick closing valve is a Marine valve controlled by air pressure, which is used to quickly close or open the flow of gas or liquid on the pipeline. Pneumatic quick closing valve is widely used in the field of ships because of its compact structure, simple operation, high reliability, and high pressure and temperature. Pneumatic quick closing valves are often used in boilers, steam powered machinery, oil pumps and pipeline devices.
Principle
Pneumatic quick closing valve is usually composed of three parts: control mechanism, actuator and interface. The control mechanism controls the operation of pneumatic quick closing valve through control components such as solenoid valve, and the actuator receives signals from the control mechanism to quickly open or close the pipeline flow through pneumatic components such as cylinders. The interface part of the pneumatic quick closing valve can be connected to the electronic control instrument, joint and pipeline system.
Process of Work
When the control mechanism receives the command, it will send the air pressure signal to the cylinder through the solenoid valve and other components, and directly change the air pressure state inside the cylinder, so as to change the switching state of the pneumatic quick closing valve and realize the control of the effective flow of the pipeline. Through the combination and adjustment of different air pressure signals, pneumatic quick closing valve can realize a variety of accurate operation modes, including fixed value control, remote control and other ways.
Advantages
Pneumatic quick closing valve has many advantages such as simple structure, small volume, light weight, quick response, high control precision, strong reliability and wide adaptability. It does not require continuous power input, so it can work well in harsh working environments. At the same time, the pneumatic quick closing valve has high reliability, stable operation, not easy to malfunction and failure, and has a long service life.
