Problems solved by technology

[0002] High-pressure valves are widely used in pipelines that transmit high-pressure media. High-pressure valves are simple in structure, convenient to manufacture and maintain, small in working stroke, short in opening and closing time, good in sealing performance, small in friction between sealing surfaces, and long in service life. The disadvantage is that the fluid resistance is large, and the force required for opening and closing is relatively large. It is not suitable for media with particles, high viscosity, and easy to coke, and the adjustment performance is poor. The action time is too long and the response is slow, resulting in a decrease in accuracy

Abstract

The invention provides a high-pressure valve capable of being quickly regulated, and belongs to the field of valves. The high-pressure valve comprises a valve body, a valve element, a valve rod and avalve seat, wherein the upper end of the valve body is fixedly locked with a valve cover; the upper end of the valve cover is equipped with a locking-in flange; a speed reducer is fixedly arranged onthe locking-in flange; a sealing filler is arranged between the upper end of the valve rod and the valve seat; a pressure cover is fixedly arranged in the locking-in flange; and the lower end surfaceof the pressure cover is in contact with the upper end surface of the sealing filler. The high-pressure valve can realize quick regulation on the high-pressure valve, and is safe and convenient.

Description

technical field [0001] The invention belongs to the field of valves and relates to a rapidly adjustable high-pressure valve. Background technique [0002] High-pressure valves are widely used in pipelines that transmit high-pressure media. High-pressure valves have a simple structure, are more convenient to manufacture and maintain, have small working strokes, short opening and closing times, good sealing performance, small friction between sealing surfaces, and long service life. High-pressure valves The disadvantage is that the fluid resistance is large, and the force required for opening and closing is relatively large. It is not suitable for media with particles, high viscosity, and easy to coke, and the adjustment performance is poor. The action time is too long and the response is slow, resulting in a decrease in accuracy. Contents of the invention [0003] The problem to be solved by the present invention is to provide a high-pressure valve with simple structure, c...
