Description

Technical Field

[0001] The utility model relates to the technical field of refrigerant safety, in particular to a refrigerant refrigeration safety device. Background Art

[0002] The refrigerant is an intermediate cooling medium that transfers the heat from the cooled system (object or space) to the refrigerant in an indirect cooling refrigeration device. This intermediate cooling medium is also called the second refrigerant. In air conditioning engineering, industrial production and scientific experiments, refrigeration devices are often used to indirectly cool the objects to be cooled, or the cold generated by the refrigeration device is transported over long distances. At this time, an intermediate substance is required to be cooled in the evaporator and then used to cool the objects to be cooled. This intermediate substance is called a refrigerant. Freon in household air conditioners is a type of refrigerant.

[0003] When the refrigerant is transported in the delivery pipeline, the delivery pipeline is often blocked, causing the pressure in the delivery pipeline to increase, affecting the normal operation of the refrigeration equipment, and even causing the delivery pipeline to burst, requiring shutdown for repairs. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] The technical problem to be solved by the utility model is that the refrigerant blocks the delivery pipeline and even ruptures the delivery pipeline, thus affecting the operation of the refrigeration equipment.

[0006] (II) Technical solution

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a refrigerant refrigeration safety device, including a refrigerant delivery pipeline, the refrigerant delivery pipeline is provided with a through hole, the outside of the refrigerant delivery pipeline is provided with a buckle that wraps the refrigerant delivery pipeline, the top of the buckle is provided with a mounting tube that cooperates with the through hole, and the mounting tube is provided with a pressure sensor that extends into the refrigerant delivery pipeline.

[0008] As an improvement, the outer side of the refrigerant delivery pipeline is sleeved with an insulation pipe.

[0009] As an improvement, a sealing ring cooperating with the coolant delivery pipeline is provided on the inner side of the buckle.

[0010] As an improvement, the sealing ring is provided with an opening, and the pressure sensor is arranged in the opening.

[0011] As an improvement, a symmetrically arranged fixing plate is provided at the opening of the buckle, a plurality of fixing holes that cooperate with each other are evenly arranged on the fixing plate, and fastening bolts are arranged in the fixing holes.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the advantages of the utility model are: 1. The buckle can fix the pressure sensor on the refrigerant delivery pipeline. The pressure sensor can monitor the pressure in the refrigerant delivery pipeline in real time and feed back the data to the control device. The control device controls the refrigeration device to stop working and sound an alarm to remind people to carry out maintenance; 2. The sealing ring can make the buckle fit on the refrigerant delivery pipeline. BRIEF DESCRIPTION OF THE DRAWINGS
