Abstract

The low-pressure circulating barrel comprises a barrel body, an air inlet and an air outlet are formed in the top of the barrel body, a backflushing opening is formed between the air inlet and the air outlet, an injection pipe is arranged in the barrel body, the bottom of the injection pipe is connected with a conveying pipe, one end of the conveying pipe is connected with an external pipe, and the other end of the conveying pipe is connected with an internal pipe. And an external box is fixedly arranged on the outer side of the barrel body. By arranging the external box, the external pipe and the conveying pipe, ammonia liquid entering the injection pipe from the air inlet is circularly conveyed in the barrel body through the conveying pipe and then enters the barrel body, the vortex phenomenon generated when the liquid enters the pump is greatly reduced, meanwhile, the resistance loss is reduced, and the liquid can adapt to the temperature in the barrel body in the conveying pipe when entering the barrel body, so that the stability of the liquid is improved. And when the liquid level reaches the warning height, the electromagnetic valve and the check valve are opened, the liquid can be conveyed into the external connection box from the external connection pipe, and accidents caused by too high liquid level are avoided.

Description

technical field [0001] The invention relates to the technical field of cold storage equipment, and more specifically, the invention relates to a low-pressure circulation barrel. Background technique [0002] In the field of refrigeration, liquid ammonia is a commonly used refrigerant. The low-pressure circulation barrel is a kind of circulation barrel, which is installed in the ammonia pump liquid supply refrigeration system. Its function is to ensure sufficient supply of low-pressure ammonia liquid to the ammonia pump. In the process of use, the low-pressure circulation barrel storing liquid ammonia and the ammonia pump are usually assembled together to form a barrel-pump integrated cooling device, which has functions such as liquid level display and super high alarm. The liquid level display device is based on the principle of a connector, and a transparent liquid level tube connected to the inside of the low-pressure circulation tank is set outside the low-pressure circul...
