During the development process, the R&D team performed a three-dimensional steady-state steady-state numerical simulation of the internal flow state of the slide-type regulator valve at different opening degrees, analyzed the internal pressure, velocity, and flow line distribution of the valve, and obtained the flow characteristics of the valve. The flow resistance characteristics and the influence of different structural parameters of the throttle slot of the sliding plate type control valve on the flow characteristics of the valve realize the optimal design of the valve structure.

The “X7020 4” Class 300”, a sliding-type control valve developed by the company, has the advantages of compact structure, short stroke, fast operation speed, and avoidance of particulate medium erosion, etc. It can be used in combination with solenoid valves and other pneumatic components to achieve the cut-off function. Can also be widely used in petroleum, chemical and other industries of the automatic control system, suitable for high precision gas, liquid and steam process media.

According to the relevant person in charge of Chongqing University of Technology, the product R&D was completed under the funding of the “Chongqing City Application Development Plan” project. Currently, the product has been promoted in China and has been exported to Iran’s national oil company, achieving a good economy. Benefits and social benefits.
