Embodiment Construction
[0026] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0027] The specific embodiment of integrated valve of the present invention, as Figure 1 to Figure 4 As shown, the integrated valve is used in the process of opening and deflation of high-pressure containers. It includes a valve body 5. The front end of the valve body 5 is provided with an air outlet channel. The air outlet channel includes a valve body inlet section 7 and a valve Body outlet section 8, valve body inlet section 7 is provided with a valve body inlet 501 (i.e. gas cylinder outlet), valve body outlet section 8 is provided with a valve body outlet 504, the size of the valve body inlet section 7 It is larger than the size of the air outlet section 8 of the valve body, and a four-way structure is arranged on the air outlet channel of the valve body, and the four ports of the four-way structure are respectively provided with a valve core 506, ...

The invention discloses an integrated valve and a gas cylinder using the integrated valve. The integrated valve comprises a valve body, and a valve core which is arranged in the valve body, wherein the valve body is provided with an exhaust channel, and is characterized in that the valve body is also provided with a compression chamber communicating with the exhaust channel; the valve core comprises a piston part positioned in the compression chamber and an end sealing part which can extends into the exhaust channel to control the connection and disconnection of the exhaust channel; a bearing surface for bearing the pressure of an inlet of the exhaust channel to drive the valve core to move toward the compression chamber is arranged on one side, close to the exhaust channel, of the piston part; the compression chamber is connected with a manual switch and an electric switch communicating with the outside; the compression chamber communicates with the outside by the manual switch, and the valve core is pushed by high-pressure gas to move toward the compression chamber, so that the exhaust channel communicates, and exhaustion is realized; under a condition of having an error of the manual switch, the compression chamber communicates with the outside by the electric switch, so that the variety of driving forms is ensured, and the structure is comparatively simple.
Description
technical field [0001] The invention relates to an integrated valve and a gas bottle using the integrated valve. Background technique [0002] In actual production and life, integrated valves for gas delivery are widely used in civil fields such as welding, cutting, chemical industry, medicine, hygiene, and electronics industry, especially in the inflation and exhaust of gas cylinders. [0003] In the prior art, such as the integrated valve disclosed in the Chinese patent document with the authorized announcement number CN104214366B, it includes a valve body, the valve body is provided with an air outlet channel, and the valve body is equipped with a valve core that guides and moves in the front and rear directions. The body is provided with a driving mechanism connected with the valve core for driving the valve core to move forward so that the valve core blocks the air outlet channel and for driving the valve core to move backward to make the air outlet channel conduct.
