Embodiment Construction

[0028] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] The invention provides a protection valve, referring to Figure 1 to Figure 7 , In one embodiment, the protection valve includes a valve body 1 , a sealing plug 2 and an elastic member 3 .

[0030] The valve body 1 includes a side wall 11, a bottom wall 12, and a valve cavity 13 formed by the bottom wall 12 and the side wall 11. The bottom wall 12 is provided with a return hole 143, and the side wall 11 is provided with a first channel 141 and a second channel. Second channel 142.

[0031] The sealing plug 2 is arranged in the valve cavity 13 and is slidably and sealedly connected with the side wall 11. A return air chamber 15 is formed between the sealing plug 2 and the bottom wall 12. A bypass groove 23 is opened on the side wall surface 22 of the sealing plug 2. The sealing plug 2 has an initial position, ...

Abstract

The invention discloses a protective valve, a compressor and an air conditioner. The compressor comprises a compression cylinder, a liquid storage tank and a pressure valve. An air cylinder and an exhaust cavity communicating with an air outlet of the air cylinder are arranged in the compression cylinder. The liquid storage tank communicates with an air inlet of the air cylinder. One end of the pressure valve communicates with the exhaust cavity, and the other end of the pressure valve communicates with the liquid storage tank. The pressure valve is in an open state when the pressure of the exhaust cavity is lower than a preset threshold value and is in a closed state when the pressure of the exhaust cavity is higher than the preset threshold value. According to the compressor, the pressure valve is arranged in a refrigerant circuit, when refrigerants are injected into the compressor, the pressure valve is in the open state since the pressure of the exhaust cavity is lower than the preset threshold value, part of the refrigerants can enter the liquid storage tank through the pressure valve, the front-back pressure difference of the air cylinder before the compressor is started is small, and the compressor protection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a protection valve, a compressor and an air conditioner. Background technique [0002] The split type air conditioner is divided into an indoor unit and an outdoor unit, and the compressor of the air conditioner is generally installed in the outdoor unit. During the production process of the air conditioner, after the air conditioner tooling is completed, the refrigerant needs to be charged into the compressor. Before the air conditioner compressor is charged with refrigerant, the air and moisture in the compressor need to be pumped out first, and then the refrigerant is charged from the condenser. In the refrigerant circulation circuit, the condenser communicates with the exhaust port of the compressor, and after the refrigerant flows through the condenser, it enters the compressor from the exhaust port of the compressor. Because the cylinder in the compressor ...
