Description

Technical Field

[0001] This utility model relates to a compressor valve sealing element, and more particularly to a compressor valve sealing element with a flexible synchronizing plate, belonging to the technical field of sealing elements. Background Technology

[0002] The sealing element of a compressor valve mainly consists of a valve ring assembly, a synchronizing plate, and a spring. The valve ring assembly reciprocates between the valve seat and the valve cover, controlling the inflow and outflow of gas. The synchronizing plate ensures the synchronicity of the movement of each valve plate in the valve ring assembly. While the valve ring assembly reciprocates, the synchronizing plate also reciprocates. During the reciprocating motion of the synchronizing plate, its side edge rubs against the inner surface of the valve body. Over time, this friction can cause wear on the side edge of the synchronizing plate, reducing the airtightness between the synchronizing plate and the valve body, leading to air leakage or even failure of the compressor valve.

[0003] Therefore, it is urgent to improve the sealing element of the compressor valve with flexible synchronizing plate to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a compressor valve sealing element with a flexible synchronizing plate. The valve ring assembly moves synchronously through an elastic plate, a first hard pad, and a second hard pad. The arc-shaped buffer plate is made of soft rubber. When the first and second valve rings move, the arc-shaped buffer plate deforms, preventing the side of the synchronizing plate from rubbing against the inner side of the valve body. At the same time, a sealing ring is provided on the outer side of the arc-shaped buffer plate, which is embedded in the sealing groove, further increasing the sealing performance between the synchronizing plate and the side of the valve body.

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figures 1-6 As shown, the compressor valve sealing element with flexible synchronizing plate provided in this embodiment includes a valve seat 1, a valve cover 2, and a valve ring assembly 3. The valve ring assembly 3 includes a first valve ring 301 and a second valve ring 302. The valve ring assembly 3 is located between the valve cover 2 and the valve seat 1. A synchronizing plate assembly 4 is provided between the valve cover 2 and the valve seat 1. The synchronizing plate assembly 4 includes a first rigid pad 401, a second rigid pad 402, an elastic plate 403, and an arc-shaped buffer plate 404. Among them, the second rigid pad 401... The rigid pad 402, the elastic sheet 403, and the arc-shaped buffer sheet 404 form a ring structure. The first rigid pad 401 is fixedly connected to the bottom surface of the first valve ring 301, the second rigid pad 402 is fixedly connected to the bottom surface of the second valve ring 302, the inner side of the elastic sheet 403 is fixedly connected to the first rigid pad 401, the outer side of the elastic sheet 403 is fixedly connected to the second rigid pad 402, and the inner side of the arc-shaped buffer sheet 404 is fixedly connected to the outer side of the second rigid pad 402. Next, a sealing ring 5 is provided on the outer side of the arc-shaped buffer plate 404, and a sealing groove 6 is provided on the inner side wall of the valve cover 2. The sealing ring 5 is embedded in the sealing groove 6. The first valve ring 301 and the second valve ring 302 reciprocate between the valve cover 2 and the valve seat 1. The first hard pad 401 and the second hard pad 402 protect the bottom of the first valve ring 301 and the second valve ring 302. The elastic plate 403 connects the first hard pad 401 and the second hard pad 402. When valve ring 301 or valve ring 302 moves, it drives another valve ring to move through elastic plate 403. The arc-shaped buffer plate 404 is made of soft rubber. When valve ring 301 and valve ring 302 move, the arc-shaped buffer plate 404 deforms, so that the side of the synchronization plate does not rub against the inner side of the valve body. At the same time, a sealing ring 5 is provided on the outer side of the arc-shaped buffer plate 404. The sealing ring 5 is embedded in the sealing groove 6, which further increases the sealing between the synchronization plate and the side of the valve body.

[0024] Furthermore, such as Figure 1 as well as Figure 2 As shown, the inner bottom surface of the valve seat 1 has multiple spring grooves 7, and a guide rod 8 is provided in the spring groove 7. The surfaces of the first valve ring 301 and the second valve ring 302 have guide grooves 9. The guide groove 9 is an elongated hole along the radial direction of the valve ring. The guide rod 8 passes through the guide groove 9. The guide rod 8 and the guide groove 9 guide the first valve ring 301 and the second valve ring 302 to prevent the first valve ring 301 and the second valve ring 302 from deflecting along the center. At the same time, the guide groove 9 is an elongated hole along the radial direction of the valve ring to prevent the valve ring from jamming when it moves up and down.

[0025] Among them, such as Figure 1 as well as Figure 2 As shown, a sealing spring 10 is provided in the spring groove 7. The top of the sealing spring 10 abuts against the first hard pad 401 and the second hard pad 402. The sealing spring 10 is in close contact with the first valve ring 301 and the second valve ring 302 on the surface of the valve cover 2.

[0026] Among them, such as Figure 1 as well as Figure 6 As shown, the upper surfaces of valve ring 301 and valve ring 302 are provided with rubber pads 11. The rubber pads 11 are the same shape and size as the valve rings. Valve ring 301 and valve ring 302 reciprocate between valve cover 2 and valve seat 1. The rubber pads 11 reduce the impact of valve ring 301 and valve ring 302 on valve cover 2.

[0027] Among them, such as Figure 1 As shown, the upper surface of the valve cover 2 is provided with multiple air inlets 12, and the inner bottom surface of the valve seat 1 is provided with multiple air outlets 13. The air inlets 12 and air outlets 13 are multiple arc-shaped grooves. Gas enters from the valve cover 2 and flows out from the bottom of the valve seat 1. The arc-shaped grooves make the air inlet of the valve cover 2 uniform, so that the first valve ring 301 and the second valve ring 302 are subjected to equal forces at all points.

[0028] Among them, such as Figure 1 As shown, multiple air passage holes 14 are provided on the surfaces of valve ring 301 and valve ring 302. The air passage holes 14 do not overlap with the air inlet hole 12. The air passage holes 14 are used for gas to pass through valve ring 301 and valve ring 302. At the same time, the air passage holes 14 do not overlap with the air inlet hole 12. When valve ring 301 and valve ring 302 are in close contact with the surface of valve cover 2, valve cover 2 is sealed.

[0029] Among them, such as Figure 1 as well as Figure 2 As shown, a sealing gasket 15 is provided on the contact surface between the valve seat 1 and the valve cover 2. The sealing gasket 15 is used to increase the airtightness between the valve seat 1 and the valve cover 2.

[0030] like Figures 1-6As shown, the principle of the compressor valve sealing element with flexible synchronizing plate provided in this embodiment is as follows: Valve ring 301 and valve ring 302 reciprocate between valve cover 2 and valve seat 1. Guide rod 8 and guide groove 9 guide valve ring 301 and valve ring 302 to prevent them from deflecting around the center. At the same time, guide groove 9 is an elongated hole along the radial direction of the valve ring to prevent the valve ring from jamming during reciprocating motion. The sealing spring keeps valve ring 301 and valve ring 302 tightly against the surface of valve cover 2. The rubber pad 11 on the upper surface of valve ring 301 and valve ring 302 reduces the pressure on valve ring 301 when they reciprocate between valve cover 2 and valve seat 1. The impact of valve ring 301 and valve ring 302 on valve cover 2 is mitigated by the protection of the bottom of valve ring 301 and valve ring 302 by hard pads 401 and 402. An elastic sheet 403 connects the hard pads 401 and 402. When valve ring 301 or valve ring 302 moves, the elastic sheet 403 drives the other valve ring to move. The arc-shaped buffer sheet 404 is made of soft rubber. When valve ring 301 and valve ring 302 move, the arc-shaped buffer sheet 404 deforms, preventing the side of the synchronizing plate from rubbing against the inner side of the valve body. Simultaneously, a sealing ring 5 is provided on the outer side of the arc-shaped buffer sheet 404, embedded in the sealing groove 6, further increasing the sealing between the synchronizing plate and the side of the valve body.
