Problems solved by technology
Multiple capillary tubes are used in parallel to reduce the flow rate to solve the problem of the frequency conversion refrigerator, but it is impossible to control the frequency conversion refrigerator compressor to increase or decrease with the heat load of the refrigerator, that is, it is impossible to selectively use the number of capillary tubes according to the refrigerant flow rate, which is mainly It is the inventor who has not found a valve matching the capillary on the market, and the present invention is born from this

The invention discloses an overpressure connecting valve of a household refrigerator. The overpressure connecting valve comprises a valve body and a sealing cap installed on the valve body. A spring seat is arranged between the sealing cap and the valve body. A spring is arranged on the spring seat and connected with a valve element. A liquid inlet channel and a liquid outlet channel are formed in the valve body. The valve element is arranged at a liquid outlet of the liquid inlet channel, and the liquid outlet of the liquid inlet channel can be opened or closed by the valve element so as to make the liquid inlet channel and the liquid outlet channel be connected or disconnected. Under the condition that multiple capillary tubes are connected in parallel for throttling, the overpressure connecting valve is matched with the capillary tubes for use, and the number of the adopted capillary tubes can be selected according to the magnitude of flow of a refrigerating agent, so that the flow of the liquid refrigerating agent is adjusted and controlled more effectively, and the proper functional characteristics of the variable frequency refrigerator are improved.
Description
technical field [0001] The invention discloses an overpressure conduction valve for household refrigerators. Background technique [0002] The refrigeration system in the refrigerator is mainly composed of a compressor, a condenser, a capillary tube and an evaporator. In the refrigeration system, the refrigerant is compressed from a low-temperature and low-pressure gaseous refrigerant to a high-temperature and high-pressure gaseous refrigerant, and then enters condensation. Then it enters the throttling device (capillary tube) for throttling and pressure reduction, and finally enters the evaporator to change the refrigerant from liquid to gas, thus forming a refrigeration cycle. The current frequency conversion refrigerator compressor mainly uses frequency conversion technology to change the fixed power grid frequency of 50HZ to a variable frequency of 30 to 130HZ. Reduce the flow rate of liquid refrigerant. However, the current frequency conversion household refrigerators ...
