Problems solved by technology

[0002] As known, in actual production and life, integrated valves for gas delivery are widely used in civil fields such as welding, cutting, chemical industry, medicine, sanitation, electronics industry, etc., especially in the gas cylinder inflation and exhaust. Therefore, there are more and more functional requirements for integrated valves in the industry, such as the need to install pressure sensors on integrated valves, and the need to miniaturize the volume of integrated valves. Traditional integrated valves are difficult to achieve these functions due to structural reasons. They are commonly used at home and abroad. The pressure sensors are relatively large in size, and it is difficult to install them directly on the valve body of the integrated valve;
[0003] Chinese patent (CN104214366B) discloses an integrated valve. The integrated valve described in this patent includes a valve body. The valve body is provided with an air outlet channel. It is connected with the spool to drive the spool to move forward so that the spool blocks the air outlet channel, and a drive mechanism for driving the spool to move backward to make the air outlet channel conduct. The drive mechanism includes a manual drive part and The push rod is pushed forward and backward by the driving part, and the push rod cooperates with the drive valve core for pressure transmission. There is also a valve core reset structure in the valve body. The spool has no effect, the spool reset mechanism drives the spool to block the gas outlet channel, and the gas outlet channel is in a cut-off state. When it is necessary to deflate the gas cylinder, the driving mechanism drives the spool to move backward to make the gas outlet channel conduct, and the gas can pass through the gas outlet channel. The exhaust is cut off by the active movement of the valve core. Although the integrated valve can realize the deflation of the gas cylinder, the driving mode of the integrated valve is operated by manual driving structure, which makes the operation time-consuming and laborious for the user, and the integrated valve cannot Inflate the gas cylinder without pressure detection, overpressure deflation and other functions

Abstract

An integrated valve for inflating and deflating gas cylinders relates to the field of integrated valves, comprising a valve body and an initiating device. The valve body is provided with a vertical passage, and a valve core is correspondingly arranged in the passage. The outer wall of one end of the valve core is provided with a sealing ring, a cavity A is formed between the end head and the passage, the other end of the valve core is provided with a boss inserted into a spring correspondingly, and the valve core can move up and down in the passage through a piston structure. The inside of thevalve core is provided with a cavity B, and one end of the cavity B close to a plugging cap is provided with an opening. A cavity C is arranged between the sealing ring of the valve core and the piston structure, wherein the cavity C communicates with the cavity B, the cavity C communicates with an air inlet port correspondingly, and the external wall of the valve is provided with a pressure sensor and an inflation valve. Between the surface of the boss of the valve core and the plugging cap, a cavity D is arranged, the cavity B communicates with the cavity D, and the cavity D is connected with the initiating device through an air passage. The problem of large volume of the integrated valve is effectively solved, and the functions of pressure detection, inflation and deflation, overpressure deflation, remote electric control bottle opening function are realized.
