Description

Technical Field

[0002] A regulating valve, also known as a control valve, generally consists of an actuator and a valve. In the field of industrial automation process control, it is the final control element that receives control signals from the regulating control unit and uses power to change process parameters such as medium flow rate, pressure, temperature, and liquid level.

[0003] However, there are inconveniences when the valve core is opened. When the valve core is opened, the medium will impact the valve core instantly.

After long-term use, the accuracy of the valve stem will deviate, affecting the normal use of the valve. Therefore, it is necessary to provide a new angle control valve to solve the above technical problems. Utility Model Content

[0033] The working principle of the angle regulating valve provided by this utility model is as follows:

[0034] First step: When the medium flows in from the inlet 7 at the bottom of the valve seat 2, it first passes through the filter plate 9 of the throttling mechanism. The filter plate 9 can intercept larger particulate impurities in the medium to avoid clogging the subsequent throttling channel. The filter plate 9 is fixedly connected to the upper throttling plate 10 and throttling plate 2 11 through the connecting ring 12 to form a three-stage filtration and throttling structure. After passing through the filter plate 9, the medium passes through the throttling plate 2 11 and the throttling plate 10 in sequence. The throttling holes 2 14 on the throttling plate 2 11 and the throttling holes 13 on the throttling plate 10 are staggered to form a tortuous flow channel, which can reduce the impact force of the medium, thereby effectively reducing fluid noise and improving throttling efficiency.

[0035] The second step: The sealing ring 24 between valve body 1 and valve stem 5, the sealing ring 25 between sleeve 4 and valve stem 5, and each sealing ring (sealing ring 26 to sealing ring 29) form a multiple sealing structure, which effectively prevents media leakage and ensures the valve's sealing performance under high pressure.
