a pneumatic valve

Abstract

The invention discloses a novel high-efficiency air pressure valve. The hovel high-efficiency air pressure valve comprises a jacking block, a pressure release block and a mounting block which are mounted and connected from the top down, a plurality of counterweights are mounted at the top of the jacking block, an exhaust jacking block is arranged at the bottom of the jacking block, the bottom of the exhaust jacking block is of a planar structure, the side of the exhaust jacking block is of a downwardly projected cambered surface structure, the pressure release block comprises a jacking section, a first connecting section and a second connecting section sequentially from the top down, the jacking section, the first connecting section and the second connecting section are of an integrally formed structure, the interior of the jacking section is provided with a jacking block-mounting socket, the sidewall of the jacking block-mounting socket is provided with a pressure relief vent, the mounting block is fitted on a second external thread structure of the second connecting section, the interior of the mounting block is provided with an air hole, and the air hole communicates with the air inlet. The upper pressure limit of the novel high-efficiency air pressure valve can be regulated by changing the number of the counterweights on the jacking block, so the novel high-efficiency air pressure valve has a good pressure release control function.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of pneumatic valves, in particular to the technical field of pneumatic valves. [0003] 【Background technique】 [0004] The pneumatic valve uses gas pressure to control the movement of the main valve core to change the flow direction of the gas. The control methods are divided into three types: pressurization control, pressure relief control and differential pressure control. Pressurization control means that the pressure of the added control signal is gradually increased. When the air pressure is controlled to the operating pressure of the valve core, the main valve will change direction; pressure relief control means that the pressure of the added air control signal is reduced. When the pressure is reduced to a certain value, the main valve will change direction; the differential pressure control is to make the main valve core change direction under the action of the pressure difference at both end...

AI Technical Summary

Problems solved by technology

The existing air pressure cannot adjust the pressure upper limit according to the specific use conditions, the sensitivity of the air pressure valve is low, and the existing air pressure valve has poor sealing effect and lacks a corresponding filtering structure, not only it is easy for impurities in the air to block the airflow channel, but also the air The impurities in it are easy to invade the interior of the equipment, causing damage to the internal parts of the equipment
