Problems solved by technology

During the replenishment process, as the liquid nitrogen in the storage tank gradually decreases, there is not enough pressure in the storage tank, so that the replenishment of liquid nitrogen is interrupted, so it cannot continuously, effectively and fully supply the required liquid nitrogen to the refrigeration equipment nitrogen
In addition, when the replenishment is interrupted, it is very likely that there is only insufficient pressure in the storage tank and there is residual liquid nitrogen, so that the liquid nitrogen in the storage tank cannot be fully utilized and causes waste
In addition, when the replenishment is interrupted, the operator cannot know the condition of the liquid nitrogen in the storage tank, which is prone to safety problems during the replacement of the storage tank

Abstract

The invention provides a liquid refrigerant supplementing device. The liquid refrigerant supplementing device is used for supplementing liquid refrigerant in a storage tank to a refrigerating device and comprises a pressurizing device, a sealing assembly, a gas inlet pipe and a liquid conveying pipe, wherein the pressurizing device is used for conveying gas into the storage tank so that the refrigerant in the storage tank can be discharged out of the storage tank, the sealing assembly is connected with an opening of the storage tank in a sealed manner, the gas inlet pipe enables the pressurizing device to communicate with the storage tank through the sealing assembly so that gas in the pressurizing device can be conveyed to the storage tank, and the liquid conveying pipe enables the storage tank to communicate with the refrigerating device through the sealing assembly so that the refrigerant in the storage tank can be conveyed to the refrigerating device. According to the liquid refrigerant supplementing device, continuous and accurate supplementation of the liquid refrigerant can be achieved, the safety is improved, and operation is convenient and rapid.

Description

technical field [0001] The invention relates to a liquid refrigerant replenishment device, in particular to a liquid nitrogen replenishment device. Background technique [0002] In the prior art, a storage tank storing a liquid refrigerant such as liquid nitrogen is usually used to replenish the refrigerant to the refrigeration equipment. During the replenishment process, as the liquid nitrogen in the storage tank gradually decreases, there is not enough pressure in the storage tank, so that the replenishment of liquid nitrogen is interrupted, so it cannot continuously, effectively and fully supply the required liquid nitrogen to the refrigeration equipment nitrogen. In addition, when the replenishment is interrupted, it is likely that there is residual liquid nitrogen in the storage tank due to insufficient pressure, so that the liquid nitrogen in the storage tank cannot be fully utilized and causes waste. In addition, when the replenishment is interrupted, the operator c...
