Abstract
The invention discloses a compressor valve block, which is characterized by the following: fixing a bigger diameter circle rubber pad than outlet opening diameter on the head of outlet opening, which is made of high-temperature rubber; the rubber is soft material to further soften in high temperature compressor, which products less noise than the noise impacted by metal; the rubber pad can seal the gap between valve block and outlet opening to prevent leaking when the valve block deforms a little.
Description
Technical field
The present invention relates to a kind of improvement of compressor valve chip architecture.
Background technique
As shown in Figure 1, 2, valve block 2 one ends are fixed on the upper bearing (metal) 3 with screw, the other end touch upper bearing (metal) relief opening 1, and when pressurized gas reached certain pressure in the cylinder, valve block was close to relief opening 1 one ends and will be flicked, cylinder is discharged in exhaust, after discharging certain gas, gas pressure reduces in the cylinder, and valve block is because tough elastic recoil itself, be adjacent to relief opening once more, form one step completed exhaust process.Because in the working procedure of compressor, the resilience number of times of per minute valve block can reach 3000 times, so the valve block of general compressor plant produced all adopts the alloy manufacturing.Though valve block is very thin very little, it is one of essential elements in the compressor reliability, and it directly influences gas delivery efficiency, delivery pressure, energy consumption and the maintenance period of compressor, is the key that compressor runs well.
At present, the valve block of existing compressor remains in some defectives, mainly contains following 2 points:
First, because valve block is that metal is made, last axle relief opening also is that metal is made, when compressor operating, valve block acts frequently, and constantly clashes into relief opening with high frequency, forms the strike note between the metal, can clearly hear " clatter clatter " that a kind of frequency is very high when compressor operating, this is one of main noise source of compressor.
Second, the general light weight of valve block, softer, though it is through strict processing, but in transportation process and using process, still cause bending deflection easily, form the gap between valve block and the relief opening, a part of gas is just let out when not reaching compression ratio, cause cold power deficiency.
Summary of the invention
The present invention provides a kind of compressor valve plate that prevents to be out of shape, to reduce the compressor valve plate of noise for solving the problem that exists in the above-mentioned technology, its objective is.
For achieving the above object, the technical solution used in the present invention provides a kind of compressor valve plate, and wherein: the head exhaust ports at valve block fixedly installs a round rubber pad that is slightly larger than diameter of outlet.
Described rubber pad is made of high-temperature resistant rubber.
Effect of the present invention: the first, rubber is soft material, and particularly when compressor operating, the compressor inside temperature is higher, and rubber can further soften, and the noise of rubber bump relief opening generation will be much smaller than the noise of bump generation between the metal like this.The second, fixedly behind the rubber, under the situation of valve block micro-strain, rubber pad can seal the space between valve block and the relief opening to the valve block head, reaches to prevent the effect revealed.

Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated compressor valve plate of the present invention.
Shown in Fig. 2,3, compressor valve chip architecture of the present invention is to fixedly install a round rubber pad 4 that is slightly larger than diameter of outlet at head relief opening 1 place of valve block 2, and rubber pad is made of high-temperature resistant rubber.
Compressor valve plate of the present invention is achieved in that based on above structure at the head of valve block 2, improve at the main position of bump relief opening 1 during valve block 2 motions just.At exhaust valve plate head exhaust ports 1 a bonding round rubber pad 4 that is slightly larger than diameter of outlet, the rubber pad center of circle overlaps with the exhaust valve plate head rounded portions center of circle, also overlaps with relief opening 1 center of circle simultaneously.The rubber pad bottom surface is circular, and top is circular arc, can make the better tightness between valve block 2 and the relief opening 1 like this.Thickness does not melt when being controlled at 165 ℃ two millimeter.Because valve block 2 acts frequently, and the compressor inside temperature is higher during work, so general tackiness agent can't reach good effect, rubber pad 4 has the danger that comes off, so rubber pad 4 can adopt rubber bonding automatically with the combination of valve metal film, promptly rubber is heated to fusing point, be bonded on the valve block 2 after cooling immediately reach bonding effect, and need carry out reliability test in advance.
