Three-way air pressure adjusting valve

Abstract

The invention discloses a three-way air pressure adjusting valve. The three-way air pressure adjusting valve comprises an air pressure bottle, a pressure conveying pipe, a protective cover, a first pipe orifice, a pressure control device, a fixed base and a second pipe orifice; the air pressure bottle communicates with the pressure conveying pipe; the end, far from the air pressure bottle, of thepressure conveying pipe is connected with the pressure control device; and the two ends of the pressure control device communicate with the first pipe orifice and the second pipe orifice. The three-way air pressure adjusting valve has the following beneficial effects: an air pressure source in a fixed pipe is used for generating impact force on a pressurization ball, so that the pressurization ball is stressed and operated in a pressurization cavity to enter a pressure source in an extrusion cavity; due to sudden reduction of the inner diameter, the pressure source is extruded and acceleratedto output through another outlet to achieve the pressurization purpose; and when the pressurization ball is stressed and operated in the pressurization cavity, the connected place of a connecting headand the pressurization cavity can be blocked to realize the air pressure accumulation and sudden increment, so that the liquid flow output change is guaranteed, meanwhile, a high pressure source canbe stably provided to liquid, and invariable impact force during liquid outputting is guaranteed.

Description

technical field [0001] The invention relates to the field of air pressure equipment, in particular to a three-way air pressure regulating valve. Background technique [0002] With the improvement of living standards, the three-way air pressure regulating valve gradually replaces the traditional one-pipe-one-control phenomenon, which makes the flow control of multiple pipes easier. The current three-way air pressure regulating valve has the following defects: [0003] The existing three-way air pressure regulating valve achieves the purpose of adjusting the liquid flow and flow speed by changing the rotation direction of the sphere, but the air pressure will change due to the change of the flow while controlling the flow. When the output liquid is used for spraying, It is impossible to maintain a stable strong pressure source all the time to ensure the impact force of the liquid output, and it is necessary to pressurize the liquid in addition to make the spraying distance mee...
