Description

Technical Field

[0001] The utility model relates to the technical field of fixing devices, in particular to a fixing device used for pressurized liquefaction of Freon. Background Art

[0002] A fixed device used for pressurized liquefaction of Freon usually refers to a Freon compressor. The interface of the Freon compressor needs to be connected to the air inlet pipe, and the gas is transported by pressurizing the inside of the compressor through the air inlet pipe. Usually, the staff adopts a direct connection method to directly fix the outlet of the air inlet pipe with the inlet end of the equipment.

[0003] However, the common direct connection method causes the connection between the two to be affected by pressure during the process of pressurizing the gas to the equipment, which makes it easy to loosen, thereby reducing the sealing effect and affecting the subsequent pressurized gas delivery. In view of this, we propose a fixing device for pressurized liquefaction of Freon. Utility Model Content

[0006] Preferably, a threaded hole is provided at the other end of the connecting pipe, and a plurality of the threaded holes are distributed in a ring shape.

[0009] Preferably, pressure-resistant dispersion fins are welded on the outer ring surface of the first movable sleeve, and a plurality of the pressure-resistant dispersion fins are distributed in a ring shape.

[0010] Preferably, the auxiliary component comprises a central guide shaft, and two ends of the central guide shaft are respectively connected to a first bracket and a second bracket, and ends of the first bracket and the second bracket are both connected to the inner surface wall of the connecting pipe.

[0011] Preferably, springs are connected to the opposite wall bodies of the first bracket and the second bracket, and the opposite ends of the two springs are respectively connected to the other end of the first movable sleeve and one end of the second movable sleeve.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] The utility model seals and fixes the interface between the intake pipe and the connecting pipe by the cooperation of the first sealing flange, the second sealing flange, the threaded rod and the nut. At the same time, under the setting of the second movable sleeve, the gas pressure generated in the connecting pipe can be initially dispersed, and under the setting of multiple pressure-resistant dispersion fins, the dispersed gas pressure can be secondarily dispersed, thereby reducing the impact on the connection between the connecting pipe and the intake pipe. Furthermore, with the assistance of two springs, the dispersion component as a whole can be movable during the process of pressurized gas transportation in the connecting pipe, thereby further reducing the buffer pressure and reducing the risk of loosening of the connection between the connecting pipe and the intake pipe.
