Problems solved by technology

In order to ensure the safety of hot ammonia during defrosting, it is necessary to control the pressure and flow of hot ammonia at the beginning of defrosting. The defrosting is done manually by workers. Before the hot ammonia defrosts, it is necessary to remove the ammonia liquid in the evaporator and related pipelines. Sometimes a large amount of ammonia liquid exists due to negligence. If a large amount of hot ammonia enters at this time, it will vaporize rapidly and cause an accident occur

Abstract

The invention provides a flow limiting device for a frost flushing pipeline of a refrigerator, which belongs to the technical field of safety equipment. The invention solves the problems that the existing refrigerating machine frosting pipeline is not easy to be frosted and has poor safety. The flow limiting device of the frosting pipeline of this freezer, the frosting pipeline includes the frosting pipe, the flow limiting device includes flange 1, flange 2, barrel section 1, barrel section 2 and spring, flange 1 is connected to the frosting The end of the pipe, the bottom end of the barrel section 2 is fixedly connected to the inner wall of the flange hole of the flange 2, and the lower wall of the barrel section 2 has several through holes distributed along the circumferential direction of the barrel section 2, and the barrel section 2 One is built into the frosting pipe, and the lower part of cylinder section 1 slides and sleeves on cylinder section 2. When cylinder section 1 moves down, cylinder section 1 can cover the through hole 1, and the top of cylinder section 1 is fixedly connected with The top cover has a through hole 2 on the top cover, the top of the spring is against the bottom surface of the top cover, and the bottom of the spring is against the top of the cylinder section 2. It can self-adaptively adjust the flow of hot ammonia used for frosting, and has good safety.

Description

technical field [0001] The invention belongs to the technical field of safety equipment, and relates to a flow limiting device, in particular to a flow limiting device for a frost flushing pipeline of a refrigerator. Background technique [0002] Refrigerators are the infrastructure for the development of the refrigeration industry. During the operation of the refrigerators, they all face the problem of frosting on the evaporator without exception. Frosting is one of the most common phenomena in the field of refrigeration engineering. It is both a refrigeration evaporator A phenomenon of effective work, but also has an adverse effect on the heat transfer of the refrigeration evaporator. The frost layer on the refrigeration evaporator coil will increase the heat conduction resistance and reduce the heat transfer effect. For the refrigeration device using the air cooler, the existence of the frost layer will also increase the flow resistance of the air, which will directly aff...
