Abstract

The utility model discloses a compressor air valve structure, which comprises a valve plate, wherein an air outlet is arranged on the valve plate, and an exhaust valve is arranged on the air outlet, and the compressor air valve structure is characterized in that the exhaust valve comprises an exhaust valve block and an elastic limiter, one end of the exhaust valve block is fixed on the valve plate, the other end of the exhaust valve block can be blocked on the air outlet, one end of the elastic limiter is fixed on the valve plate, and the other end of the elastic limiter is propped against the exhaust valve block at the air outlet; the utility model discloses can subdue the mechanical noise between discharge valve piece and the elasticity stopper to reduce air compressor's whole noise, improve operational environment.

Description

A kind of compressor valve structure

Technical field

The utility model relates to a kind of valve, particularly a kind of intake and exhaust valve that is used on the air compressor.

Background technique

The piston type air inlet and exhaust valve of conventional air compressor comprises valve plate, and valve plate is provided with suction port and relief opening, and suction valve and outlet valve are installed on suction port and the relief opening, and wherein outlet valve is made up of the position-limit mechanism of exhaust valve plate and rigidity.Because the exhaust valve plate of this outlet valve is that rigidity contacts with the rigidity position-limit mechanism, air compressor can contact with rigidity between the rigidity position-limit mechanism because of exhaust valve plate in the course of the work and produce bigger mechanical noise, thereby the noise of air compressor is increased, influence environment.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of compressor valve structure that can reduce the air compressor mechanical noise.

The technological scheme that its technical problem that solves the utility model adopts is:

A kind of compressor valve structure, comprise valve plate, described valve plate is provided with relief opening, on the described relief opening outlet valve is installed, it is characterized in that described outlet valve comprises exhaust valve plate and elasticity snubber, an end of described exhaust valve plate is fixed on the valve plate, but the other end shutoff is on relief opening, one end of described elasticity snubber is fixed on the valve plate, and the other end roof pressure is on the exhaust valve plate of exhaust ports.

As the utility model preferred embodiment, described elasticity snubber and exhaust valve plate are crisscross arranged on valve plate.

As the preferred mode of execution of the utility model, be 90 degree between described elasticity snubber and the exhaust valve plate and be crisscross arranged on valve plate.

As the improvement of the above-mentioned mode of execution of the utility model, suction valve also comprises a reinforced sheet, and an end of described reinforced sheet is fixed on the valve plate, and its other end roof pressure is on the elasticity snubber on the relief opening.

The beneficial effects of the utility model are: the structure that the utility model adopts exhaust valve plate to match with the elasticity snubber, air compressor is Elastic Contact between exhaust valve plate and the elasticity snubber in the course of the work, thereby can subdue mechanical noise between exhaust valve plate and the elasticity snubber by the elasticity snubber, reduce the overall noise of air compressor, improve operating environment.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a schematic perspective view of the present utility model;

Fig. 2 is a plan view of the present utility model;

Fig. 3 be among Fig. 2 A-A to sectional view.

Embodiment

Fig. 1 is the structural representation of a kind of mode of execution of the utility model, and compressor valve structure as shown in the figure comprises valve plate 1, and valve plate 1 is provided with relief opening 2, wherein on the relief opening 2 outlet valve is installed.

With reference to Fig. 1, Fig. 2, Fig. 3, outlet valve comprises exhaust valve plate 3, reinforced sheet 4 and elasticity snubber 5, being 90 degree between elasticity snubber 5 and the exhaust valve plate 3 is crisscross arranged on valve plate 1, wherein an end of exhaust valve plate 3 is fixed on the valve plate 1 by fastening piece such as screw 6 and pad 7, but the other end shutoff is on relief opening 2, one end of elasticity snubber 5 is fixed on the valve plate 1 by fastening piece such as screw 6 and pad 7, the other end roof pressure is on the exhaust valve plate 3 at relief opening 2 places, adopt air compressor of the present utility model Elastic Contact between exhaust valve plate and the elasticity snubber in the course of the work like this, thereby can subdue mechanical noise between exhaust valve plate and the elasticity snubber by the elasticity snubber, reduce the overall noise of air compressor, improve operating environment.

As shown in the figure, reinforced sheet 4 is fixed on the valve plate 1 by fastening screw trip bolt on the exhaust valve plate 36 and pad 7, and the other end roof pressure of reinforced sheet 4 is being positioned on the elasticity snubber 5 of relief opening 3.

The above only is preferred embodiment of the present utility model, can not limit protection domain of the present utility model with it.The utility model also can have other structural change, so long as the equalization of doing according to protection domain of the present utility model changes and modify, all should still belong in the scope that the utility model contains.
