Abstract
The utility model discloses a high-pressure relief valve. The high-pressure relief valve comprises a valve body, a flange surface, a seal plug, a spring, a spring seat, an inlet and an outlet, wherein the inlet is formed on one side of the valve body; the seal plug, the spring, the spring seat and the outlet which are arranged in the relief valve are sequentially connected; and the flange surface is arranged on one side of the seal plug. The opening and closing of the high-pressure relief valve are controlled through the seal plug under the action of spring force, so that entry and release of a refrigerant are achieved, and the normal operation of a refrigeration system is ensured; and external air can not enter an air-conditioning system, so that environmental pollution caused by the use of a fusible plug is avoided.
Description
Technical field
The utility model 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.
The model utility content
The model utility purpose: the purpose of the utility model 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 to be provided.
Technological scheme: in order to realize above purpose, the described a kind of high pressure relief valve of the utility model, 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 that the utility model provides; 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 the working principle schematic representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model.
Be illustrated in figure 1 as the described a kind of high pressure relief valve of the utility model, 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 the technical conceive and the characteristics of explanation the utility model, its objective is to let to be familiar with the also enforcement according to this of content that these those skilled in the art can understand the utility model, can not limit the protection domain of the utility model with this.Allly do equivalents or the modification of making, all should be encompassed within the protection domain of the utility model according to the utility model spirit.
