Mechanical pressure adjustable automatic switch valve

Abstract

The invention discloses a purely mechanical pressure adjustable automatic switch valve and relates to a valve. The valve is provided with a valve shell body, a sealing film I and a spherical valve core, wherein the spherical valve core is installed inside the valve shell body through the sealing film I, and a channel is arranged inside the spherical valve core. A triangular gap is formed in one side of the spherical valve core, and the bottom end of the gap ends with a sphere center position. The sphere center position is provided with a hinge. The bottom of a cavity body and the valve shell body are respectively provided with a support frame. The valve shell body is provided with a pressure transmitting device. The pressure transmitting device comprises the cavity body which is connected with the upper end of the valve shell body. A pressure transmitting spearhead is installed inside the cavity body and connected with a pressure transmitting rod. The pressure transmitting rod penetrates through the bottom of the cavity body and is connected with a pressure adjusting device used for adjusting the valve switch pressure. A sealing film II is installed between the pressure transmitting spearhead and the valve shell body, and the pressure adjusting device is installed on the support frame. One end of a control rod is connected with the hinge, and the other end of the control rod is movably installed on the pressure transmitting rod. The mechanical pressure adjustable automatic switch valve has the advantages of being of a purely mechanical structure and being capable of achieving automatic control.

Description

technical field [0001] The invention relates to a valve, in particular to a mechanical adjustable pressure automatic switch valve. Background technique [0002] Valve is an important part in pipeline connection. It directly controls the opening and closing of liquid or gas in the pipeline. It is widely used in industry, agriculture and people's daily life, and plays an important role in various equipment and pipeline transportation. . For example, in recent years, solar water heaters have become popular all over the country and have entered many households, enterprises and institutions. However, there have always been certain problems in fetching water from solar energy. For example, manually controlling the valve is not only cumbersome and inefficient, but also unable to know exactly when to turn it off and when to turn it on. Overflow will lead to waste of water; while intelligent control water fetching devices are mostly electronic, and there are shortcomings such as el...

However, there have always been certain problems in fetching water from solar energy. For example, manually controlling the valve is not only cumbersome and inefficient, but also unable to know exactly when to turn it off and when to turn it on. Overflow, resulting in waste of water; and intelligent control water fetching devices are mostly electronic, with the disadvantages of easy damage and failure of electronic components
