Abstract
The invention discloses a high-pressure decompression valve. The high-pressure decompression valve comprises a valve body, a flange surface, a sealing plug, a spring, a spring seat, an inlet and an outlet, wherein the inlet is formed on one side of the valve body; the sealing plug, the spring, the spring seat and the outlet in the decompression valve are connected with one another in turn; and the flange surface is formed on one side of the sealing plug. The high-pressure decompression valve is controlled to be opened and closed through the sealing plug under the action of spring force, so that a refrigerant can be filled and discharged, and the normal operation of a refrigerating system is ensured; and outside air cannot enter an air-conditioning system, so that the pollution to the environment due to the usage of an easily-fused plug is prevented.
Description
Technical field
The present invention relates to a kind of high pressure relief valve.
Background technique
The fusible plug that is provided with on the top of liquid storage exsiccator is used for preventing that high side pressure from raising unusually, avoids damaging compressor and condenser, when high side temperature and pressure anomaly rising; Fusible plug melts discharges into the atmosphere refrigeration agent, avoids compressor damage with this, but after the fusible plug fusing; Air can get into air-conditioning system; And fusible plug is article of consumption, is a kind of waste to resource, and also can pollute environment.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of existing technology, a kind of high pressure relief valve of a kind of compact structure, high working efficiency, reliable performance and environmental protection is provided.
Technological scheme: in order to realize above purpose, a kind of high pressure relief valve of the present invention, it comprises valve body; Flange surface, sealing plug, spring; Spring seat, entrance and exit, a side of described valve body is provided with inlet; The sealing plug that is provided with in this Decompression valves, spring, spring seat and outlet link to each other successively, and a side of described sealing plug is provided with flange surface.
Described sealing plug, spring, spring seat, entrance and exit are on same axis, and described flange surface is a non-planar surface.
Beneficial effect: a kind of high pressure relief valve provided by the invention; Kai Heguan through sealing plug control valve under the effect of spring force; The entering and the release of refrigeration agent have been realized; Guaranteed the refrigeration system proper functioning, and extraneous air can't get in the air-conditioning system, avoid using behind the fusible plug pollution environment.
Description of drawings
Fig. 1 is a working principle schematic representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
Be illustrated in figure 1 as a kind of high pressure relief valve of the present invention, it comprises valve body 1, flange surface 2, sealing plug 3, spring 4, spring seat 5, inlet 6 and outlet 7.
One side of described valve body 1 is provided with inlet 6, the sealing plug 3 that is provided with in the valve body 1, spring 4, spring seat 5 and export 7 and link to each other successively, and a side of described sealing plug 3 is provided with flange surface 2.
Described sealing plug 3, spring 4, spring seat 5, inlet 6 and outlet 7 are on same axis, and described flange surface 2 is a non-planar surface.
This Decompression valves can be contained in liquid storage exsiccator or compressor high pressure side, and when system's proper functioning, sealing plug 3 is pushed to valve body 1 under the effect of spring 4; And be close on the flange surface 2, at this moment, this Decompression valves is closed, and refrigeration agent can't be emitted; When system's internal pressure raise unusually, the spring 4 on the spring seat 5 was compressed, and valve is opened, and refrigeration agent is released out; System's internal pressure descends rapidly, and when pressure was reduced to limit value, under the effect of spring force, this valve cut out rapidly; To guarantee the proper functioning of refrigeration system, extraneous air then can't get in the air-conditioning system, has avoided using behind the fusible plug to the pollution of environment with to the consumption of resource.
Above-mentioned embodiment only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All according to the present invention spirit do equivalents or the modification of making, all should be encompassed within protection scope of the present invention.
