On-off valve device for gas-liquid mixing

Abstract

A switch valve device that can be used for gas-liquid mixing belongs to the field of medical device accessories. It includes a valve body (1) and a gas-liquid mixing device. The valve body (1) is connected with a liquid inlet pipe (7) and an air inlet pipe (8). The valve body (1) is respectively provided with a liquid inlet (15) and an air inlet. (16), wherein the liquid inlet (15) is connected to the liquid inlet pipe (7), and the valve body (1) is provided with an air inlet control mechanism for controlling the connection and disconnection of the air inlet (16) and the air inlet pipe (8), The valve body (1) drives the end of the liquid inlet pipe (7) and the air inlet pipe (8) to be sealed and inserted into the gas-liquid mixing device, and an exhaust device is connected to the upper part of the inner chamber of the gas-liquid mixing device. The valve body (1) automatically controls the on-off of the intake pipe (8), the gas-liquid is mixed in the gas-liquid mixing device, and the excess gas and the waste gas generated by the mixture are discharged through the exhaust device. The present invention is small in size, simple in structure, and The operation is convenient, and the disadvantages of complex structure, high cost and cumbersome operation of the current gas-liquid mixing device are overcome.

Description

technical field [0001] A switch valve device that can be used for gas-liquid mixing belongs to the field of medical device accessories, and in particular relates to a switch valve device that can be used for automatic control of gas-liquid mixing. Background technique [0002] Gas and liquid mixtures are widely used in various fields. In the original gas-liquid mixing device, gas and liquid have to be mixed after being controlled by various control pumps and valves, which has disadvantages such as large volume, high cost, and complicated control circuits. . Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a gas-liquid mixing switch valve device with small volume, light weight, simple structure and convenient operation. [0004] The technical solution adopted by the present invention to solve the technical problem is: the on-off valve device for gas-liquid mixing incl...

AI Technical Summary

Problems solved by technology

The valve body drives the movement of the liquid inlet pipe and the inlet pipe, and automatically controls the on-off of the inlet pipe. The inlet pipe and the liquid inlet pipe respectively inject gas and liquid into the gas-liquid mixing device, and the gas-liquid is mixed in the gas-liquid mixing device. The excess gas and the waste gas produced by mixing are discharged through the exhaust device. The invention has small volume, simple structure and convenient operation, and overcomes the shortcomings of the current gas-liquid mixing device with complex structure, high cost and cumbersome operation.
