Abstract

The invention discloses a gas discharge valve. The gas discharge valve comprises a valve seat, a valve body and a valve deck. A containing cavity is formed in the valve deck. A gas channel communicating with the containing cavity is formed in the circumferential wall of the containing cavity. A gas outlet hole communicating with the containing cavity is formed in the top wall of the containing cavity. A blind hole is formed in the valve body. The valve body is contained in the containing cavity of the valve deck. When compressed gas having a preset pressure is discharged out from a gas discharging hole, the valve body contained in the containing cavity of the valve deck is ejected by the discharged gas and is sucked to the inner side of the top wall of the containing cavity, and the compressed gas discharged from the gas discharging hole flows out from the gas channel of the valve deck. According to the gas discharge valve, when the gas is discharged, the valve body can be reliably sucked to the inner side of the top wall of the containing cavity of the valve deck; and in this way, the gas discharge valve can be reliably kept at the opened state when the gas is discharged, gas discharging is guaranteed to be smooth, and the situation that the gas discharge valve is frequently switched and fatigued and is ineffective because of gas pressure fluctuation can be avoided.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a gas discharge valve and a compressor with the gas discharge valve. Background technique [0002] In the field of valve technology, gas discharge valves can be used to control the discharge of gases. In the existing gas discharge valve, when the device equipped with the valve does not need to be exhausted, the gas discharge valve has the problem that it cannot be closed in time, resulting in the reverse flow of the discharged gas and causing damage to the device; or, when the device equipped with the valve When the device needs to be exhausted, the opening state of the valve is unstable, and it is easy to open and close frequently due to the fluctuation of the exhaust gas pressure, so that the exhaust effect is not good. Contents of the invention [0003] The purpose of the present invention is to solve at least one aspect of the above-mentioned problems and deficiencies in th...
