Description

Technical Field

[0001] This utility model relates to the field of compressor exhaust technology, specifically to a compressor exhaust valve seat. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas; it is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by a motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle. This achieves the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption). A discharge valve seat is used when the compressor discharges gas.

[0003] The existing compressor exhaust valve seat generates significant noise during exhaust due to air pressure issues, making noise reduction difficult. Summary of the Invention

[0004] The purpose of this invention is to provide a compressor exhaust valve seat to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compressor exhaust valve seat, comprising a valve seat and a threaded sleeve, wherein the valve seat has an annular positioning hole inside, and a spring is installed inside the positioning hole; a valve plate is provided at the upper end of the spring; a valve cover is provided on the upper side of the valve plate; the threaded sleeve is installed inside the valve cover; and a noise reduction connecting component is annularly provided on the outer surface of the threaded sleeve; the connecting component includes a connecting post and a damping sleeve; and a damping sleeve is provided on the outer surface of the connecting post; and an auxiliary component for noise reduction is installed outside the damping sleeve; the auxiliary component includes a connecting sleeve and blades; and blades are annularly distributed on the outer surface of the connecting sleeve.

[0006] Furthermore, the blade has a rectangular structure and is fixedly mounted on the outer surface of the connecting sleeve.

[0007] Furthermore, the auxiliary component also includes a cover plate, and the end of the connecting column is threaded with a cover plate.

[0008] Furthermore, the connecting posts and the cover plates are distributed in a one-to-one correspondence, and the ends of the connecting posts are welded with the outer surface of the threaded sleeves.

[0009] Furthermore, there are four groups of connecting components and auxiliary components, and the connecting components and auxiliary components are distributed in a one-to-one correspondence.

[0010] Furthermore, a stud is installed in the middle of the threaded sleeve, and a vent hole is provided in the annular shape inside the valve cover.

[0011] Furthermore, the diameter of the valve cover is larger than the diameter of the valve seat, and the positioning holes and springs are distributed in a one-to-one correspondence.

[0012] This utility model provides a compressor exhaust valve seat, which has the following beneficial effects:

[0013] 1. The valve seat of this utility model has a gas passage that can be covered by the valve plate, which together with the valve plate locks the intake (or exhaust) passage and withstands the pressure difference inside and outside the cylinder. When closed, the spring pushes the valve plate to fall onto the valve seat, and when opened, it suppresses the valve plate from hitting the valve cover lift limiter. The springs are distributed one-to-one with the positioning holes, which is conducive to the elastic deformation of the springs inside the positioning holes, and avoids the spring elastic deformation force from shifting, thus having the function of limiting and stabilizing.

[0014] This invention, through the design of connecting components and auxiliary components, utilizes the air pressure generated during exhaust to drive the blades and connecting sleeve to rotate about the connecting post. Combined with the design of the damping sleeve, it can increase resistance when the blades and connecting sleeve rotate about the connecting post, thereby reducing the significant noise caused by air pressure issues during exhaust.

The valve seat 1 has a positioning hole 2 annularly formed inside, and a spring 3 is installed inside the positioning hole 2. A valve plate 4 is positioned at the upper end of the spring 3, and a valve cover 5 is positioned on the upper side of the valve plate 4. The diameter of the valve cover 5 is larger than the diameter of the valve seat 1. The positioning hole 2 and the spring 3 are in a one-to-one correspondence. The sleeve 6 is installed inside the valve cover 5, and the outer surface of the sleeve 6 is provided with a connecting component 9 for noise reduction. The valve seat 1 has a gas passage that can be covered by the valve plate 4, which together with the valve plate 4 locks the intake or exhaust passage and bears the pressure difference inside and outside the cylinder. The spring 3 pushes the valve plate 4 to fall towards the valve seat 1 when closed, and suppresses the valve plate 4 from hitting the lift limiter of the valve cover 5 when open. The springs 3 are distributed one-to-one with the positioning holes 2, which is conducive to the elastic deformation of the springs 3 inside the positioning holes 2, and avoids the spring 3 elastic deformation force from shifting, thus having the function of limiting and stabilizing.

[0021] like Figure 1 and Figure 3 As shown, a stud 7 is installed in the middle of the threaded sleeve 6, and a vent hole 8 is annularly opened inside the valve cover 5. Four sets of connecting components 9 and auxiliary components 10 are provided, and the connecting components 9 and auxiliary components 10 are distributed in a one-to-one correspondence. The connecting component 9 includes a connecting post 901 and a damping sleeve 902, and the damping sleeve 902 is provided on the outer surface of the connecting post 901. The connecting post 901 and the cover plate 1003 are distributed in a one-to-one correspondence, and the outer surface of the threaded sleeve 6 is welded to the end of the connecting post 901. An auxiliary component 10 for noise reduction is installed on the outside of the damping sleeve 902, and the auxiliary component 10 includes a connecting sleeve 1001 and a blade 1002. The auxiliary component 10 also includes a cover plate 1003, and the connecting post 901... The end thread is provided with a cover plate 1003, and the outer surface of the connecting sleeve 1001 is circumferentially distributed with blades 1002.

The connecting post 901 can be welded to the outer surface of the threaded sleeve 6 according to the exhaust situation. The damping sleeve 902 is made of high temperature resistant rubber. The air pressure generated during exhaust will push the blades 1002 and the connecting sleeve 1001 to rotate about the connecting post 901. With the design of the damping sleeve 902, the resistance can be increased when the blades 1002 and the connecting sleeve 1001 rotate about the connecting post 901, thereby reducing the large noise caused by air pressure problems during exhaust.

[0022] In summary, the compressor discharge valve seat is first based on Figures 1-3The structure shown in the diagram has a gas passage that can be covered by the valve plate 4 during use. Together with the valve plate 4, it locks the intake or exhaust passage and withstands the pressure difference between the inside and outside of the cylinder. The spring 3 pushes the valve plate 4 to fall onto the valve seat 1 when closed and inhibits the valve plate 4 from hitting the valve cover 5 lift limiter when open. The springs 3 are distributed one-to-one with the positioning holes 2, which is conducive to the elastic deformation of the springs 3 inside the positioning holes 2. Then, exhaust is carried out through the vent hole 8. According to the exhaust situation, the connecting post 901 can be welded to the outer surface of the threaded sleeve 6 by welding. The damping sleeve 902 is made of high temperature resistant rubber. The air pressure generated during exhaust will push the blade 1002 and the connecting sleeve 1001 to rotate about the connecting post 901. With the design of the damping sleeve 902, the resistance can be increased when the blade 1002 and the connecting sleeve 1001 rotate about the connecting post 901.
