Quarter-turn angle valve

Abstract

The invention discloses an angular travel angle valve and relates to the technical field of a pipeline valve. A cylindrical valve element of the angular travel angle valve is directly inserted in an open cavity; an inlet is formed on the side wall of the cylindrical valve element; an outlet is formed in the bottom of the cylindrical valve element; the inlet is communicated with the outlet; when the valve is opened, the inlet is communicated with a left flange and the outlet is communicated with a lower flange; a sealing seat is arranged between the outer side wall of the cylindrical valve element and the left flange; a spring seat and a spring are arranged between the sealing seat and the left flange; the spring seat is pressed against the sealing seat by the spring; the spring seat seals the sealing seat. Not only does the angular travel angle valve disclosed by the invention have high sealing performance, high safety and a long service life, but also the valve element is stable and reliable and has low noise in the operating process.

Description

technical field [0001] The invention relates to the technical field of pipeline valves, in particular to a quarter-stroke angle valve. Background technique [0002] With the rapid development of information technology and the continuous improvement of industrial intelligence, valves, as the terminal actuators that control fluid movement in pipelines, are gradually changing the limitations of their own functions and are full of new ideas. , environmental protection, intelligence, small size, light weight, long life and other new requirements and new directions. [0003] In the gas, liquid and other fluid delivery and control systems in the industrial application field, it is often necessary to use angle valves to realize the control of various fluids according to the requirements of working conditions. Traditional angle valves mostly use straight-stroke plunger valves. This type of plunger valve realizes the fluid control of the valve through the up and down movement of the ...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the valve adopts a straight-stroke structure, the up and down movement of the valve core is likely to cause scratches and jams between the valve core and the sealing seat, which affects the service life of the valve

[0005] 2. Due to the high-speed flow of the fluid medium mixed with hard particles, not only the valve core is eroded, but also the high-speed fluid is prone to flash evaporation or cavitation. In addition, the bubble bursting process of the medium in the valve cavity will release a lot of energy, forming Cavitation not only causes strong damage to the sealing seat located at the water outlet, makes the valve tightness poor, but also easily causes safety hazards

[0006] 3. Due to the large pressure difference between the front and rear of the high-inlet and low-outlet angle valve and the fast flow rate, the stability of the general plunger valve core is poor during the adjustment process, which will generate large high-frequency vibration noise and affect product quality.
