Abstract
The utility model relates to a valve plate for compressors. A wedged projection is arranged on the front side of the head of the valve plate, and a wedged groove is arranged on the back side, opposite to the wedged projection, of the head of the valve plate. Compared with the prior art, the valve plate for the compressors has the advantages of capabilities of improving volume efficiency, avoiding extra noise, reducing exhaust pulsation, improving efficiency and the like.
Description
Technical field
The utility model relates to compressor, especially relates to a kind of compressor and uses valve block.
Background technique
Compressor is folded between compression cover and the compressor main body with valve block usually, produces a clamping force through the compression cover with being connected of compressor main body, utilizes this clamping force to compress valve block.
Existing valve block head is smooth, and the one, volumetric efficiency is lower, and the 2nd, valve block is beaten and is caused that on baffle plate the exhaust pulsation can lower efficiency.
Summary of the invention
The purpose of the utility model is exactly to provide a kind of compressor of raising the efficiency to use valve block for the defective that overcomes above-mentioned existing technology existence.
The purpose of the utility model can realize through following technological scheme: a kind of compressor is used valve block, it is characterized in that, the head front of this valve block is provided with the wedge shape convexity, is provided with wedge-shaped impression with the protruding opposing backside surface of this wedge shape.
Described wedge shape is protruding corresponding with the exhaust port of compressor.
The used material of described valve block comprises 7C27Mo2 material or GIN6 material.
Compared with prior art; The utility model extrudes a wedge surface (it is not parallel that wedge surface is meant that other parts of this face and valve block belong to planes) at the valve block head; Being superior to exhaust port is occupied a part by wedge surface on the one hand; This has just directly improved volumetric efficiency, and easy incision does not produce extra noise when valve block is closed; The groove at the valve block back side has played the effect of air cushion on the other hand, lifts when soon contacting with baffle plate at valve block, and this starting point pressure raises, and stops that valve block directly contacts with baffle plate, thereby has reduced the exhaust pulsation, has improved efficient.
If be that non-wedge surface can cause that exhaust is smooth inadequately, wedge surface is quite different.By the velocity field at exhaust screen place, can know that the part that occupies in wedge surface is a low velocity zone, can not influence compressor air-discharging.
Description of drawings
Fig. 1 is the positive structural representation of the utility model valve block;
Fig. 2 is the structural representation at the utility model valve block back side.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment 1
Shown in Fig. 1-2, a kind of compressor is used valve block, and the head front of this valve block is provided with wedge shape convexity 1, is provided with wedge-shaped impression 2 with the protruding opposing backside surface of this wedge shape.Described wedge shape protruding 1 is corresponding with the exhaust port of compressor, and the wedge type convexity is arranged in the middle of the valve block head, and the convex plane of wedge shape convexity 1 and non-convex plane portion are not parallel, and the groove plane of wedge hollow and non-groove planar surface portion are not parallel.The protruding crowning of wedge type gets into exhaust port, occupies the part of exhaust port, and this has just directly improved volumetric efficiency, and easy incision does not produce extra noise when valve block is closed; The wedge hollow at the valve block back side has played the effect of air cushion on the other hand, lifts when soon contacting with baffle plate at valve block, and this starting point pressure raises, and stops that valve block directly contacts with baffle plate, thereby has reduced the exhaust pulsation, has improved efficient.
The used material of described valve block comprises 7C27Mo2 material or GIN6 material.
Claims (3)
1. a compressor is used valve block, it is characterized in that, the head front of this valve block is provided with the wedge shape convexity, is provided with wedge-shaped impression with the protruding opposing backside surface of this wedge shape.
2. a kind of compressor according to claim 1 is used valve block, it is characterized in that, described wedge shape is protruding corresponding with the exhaust port of compressor.
