Background
At present, kinetic energy of a pipeline liquid column in a refrigeration system of a refrigeration house is continuously increased in accelerated flow, when the kinetic energy flows to an end, the direction of the pipeline is suddenly changed, the kinetic energy is suddenly changed into pressure energy by the liquid column, great impact and sound can be generated, if serious defects such as cracks, incomplete fusion, incomplete penetration and the like exist in a circumferential weld at an impact position, further expansion of the defects can be caused, and finally, the pipeline is broken to generate a liquid hammer accident. Particularly, when hot fluorine defrosting is carried out, because liquid exists in the air return pipeline, the hot fluorine inlet valve is opened too fast at the beginning of defrosting, high-pressure gas pushes the liquid in the air return pipeline to flow in an accelerating way to generate high-speed liquid flow in the air return pipeline, and a liquid hammer is generated when the liquid flow is blocked. Currently, a method for installing a liquid discharge barrel in a refrigeration system is used for relieving the liquid hammer of the system, and the method is increased in cost. And does not alleviate the liquid hammer problem of the pipeline.
SUMMERY OF THE UTILITY MODEL
Problem to above-mentioned prior art exists, the utility model provides a freezer refrigerating system hydraulic hammer buffer plays the effect that shows the buffering to the liquid hammer phenomenon in the pipeline to better protection pipe-line system prevents because of the pipeline crack that the liquid hammer caused, phenomenons such as fracture.
In order to achieve the purpose, the utility model provides a freezer refrigerating system hydraulic hammer buffer, including the condenser, respectively with the refrigerating unit and the reservoir of condenser intercommunication, respectively with the air-cooler of refrigerating unit and reservoir intercommunication to and set up in the hydraulic hammer buffer of every vertical pipeline bottom turn.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the hydraulic hammer buffering device for the refrigeration system of the refrigeration house comprises a condenser 5, a refrigeration unit 6 and a liquid storage device 7 which are respectively communicated with the condenser 5, an air cooler 8 which is respectively communicated with the refrigeration unit 6 and the liquid storage device 7, and a hydraulic hammer buffering device 9 which is arranged at the bottom end turning of each vertical pipeline 1.
In the first embodiment, as shown in fig. 2, the hydraulic hammer cushioning device 9 is composed of a baffle 2 and a support spring 3 which are arranged at the bottom end of a vertical pipeline 1;
one end of the baffle 2 is arranged on the inner wall of the corner transition position at the bottom end of the vertical pipeline 1 in a movable connection mode, and the other end of the baffle 2 is a movable end.
Furthermore, one end of a supporting spring 3 is fixed at the lower part of the baffle 2 close to the middle position, and the other end of the supporting spring 3 is fixed below the joint of the baffle 2 and the pipeline 1.
Furthermore, the size of the baffle 2 is smaller than the inner diameter of the pipeline 1, and one end of the baffle 2 is movably connected to the inner wall of the corner transition position at the bottom end of the vertical pipeline 1 through a rotating shaft.
As shown in fig. 4, the connection end of the flapper 2 is connected to the inner wall of the pipe 1 by a hinge or a bending spring.
When adopting above-mentioned spring baffle structural style, when the perpendicular downward flow of liquid column in the system, strike baffle 2 earlier, baffle 2 compression supporting spring 3 plays the effect of liquid column impact force in buffer pipeline 1, the effectual harm that prevents the liquid hammer and lead to the fact the refrigeration pipeline. The rigidity and the deformation of the spring can be determined according to the pressure of the system pipeline, and the buffering effect is more accurately achieved, so that the system pipeline is better protected, and pipeline cracks, breakage and the like caused by a liquid hammer are prevented.
