Abstract

The invention relates to a pilot-operated type automatic fluid infusion respiration valve which comprises a valve body, a pilot device and a fluid infusion device, wherein the pilot device is connected with the inner chamber of the valve body, an expiration cavity and an aspiration cavity through a pilot pipe; the fluid infusion device comprises a balance bar, a balance block and a control valve; the pilot device is arranged at one end of the balance bar; the balance block is arranged at the other end of the balance bar; a control handle of the control valve is fixedly connected with one end of the balance bar; a liquid inlet of the control valve is connected with an external fluid infusion source; a liquid outlet of the control valve is connected with the pilot device. The pilot-operated type automatic fluid infusion respiration valve has the benefits that as the lever principle is utilized, the fluid infusion amount is controlled precisely, the expiration pressure and the aspiration pressure are always guaranteed in conformity with requirement for setting pressure; as the pilot pipe technology is adopted, the liquid volatilization is effectively reduced, the feasibility and reliability of liquid pressure control valve body in expiration and aspiration are guaranteed; the technology solves the problem that the traditional physical counter weight respiration valves are easy to leak.

Description

technical field [0001] The invention relates to a breathing valve, in particular to a pilot-operated automatic fluid replenishing breathing valve. Background technique [0002] Most of the existing breathing valves use metal physical counterweight to control the set pressure of the breathing valve. When the pressure of the physical counterweight breathing valve has not reached the pressure required for exhalation, the counterweight is already in a semi-suspension state, so the sealing surface It will not be too tightly sealed, and it is very easy to cause air leakage, which will seriously pollute the surrounding environment of the equipment and waste a lot of materials. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pilot-operated automatic rehydration breathing valve, which solves the technical problems that the existing breathing valve is extremely prone to air leakage, seriously pollutes the surrounding env...
