Problems solved by technology

However, there is a problem in the above-mentioned compressor air valve: the first protective layer and the second protective layer are respectively coated on the valve seat and the lift limiter, due to the impact of the valve plate on the first protective layer and the second protective layer The force is relatively large, and it is easy to cause the protective layer to fall off under the condition of high-pressure impact

Embodiment 1

[0043] Such as figure 1 with figure 2 As shown, the compressor air valve is an open air valve, which is composed of a valve seat 1, a valve plate 2, a guide sleeve 3, a lift limiter 4, a spring 5, a bolt 6 and the like.

[0044] Among them, the valve seat 1, the guide sleeve 3, and the lift limiter 4 are sequentially sleeved on the bolt 6, the valve plate 2 is sleeved on the guide sleeve 3 and is located between the valve seat 1 and the lift limiter 4, and the guide sleeve 3 plays a guiding role on the valve plate 2. The lift limiter 4 and the bolt 6 are fixedly connected. One end of the spring 5 is fixed on the lift limiter 4, and the other end is on the back of the valve plate 2. A lock nut 7 and a lock nut 7 are arranged above the valve seat 1. It is screwed on the bolt 6 and abuts against the outer end of the valve seat 1. An anti-loosening pin 8 is provided between the bolt 6 and the lift limiter 4 for positioning, the lift limiter 4 and the valve seat 1 are positioned by ...

Embodiment 2

[0056] The structure and principle of the second embodiment are basically the same as those of the first embodiment, and the difference lies in: Image 6 with Figure 7 As shown, the compressor air valve is a closed air valve, in which the edge of the first plastic gasket 10 and the edge of the second plastic gasket 11 abut together, and the inner end surface of the lift limiter 4 has an arc Shaped limiting groove 4d, the limiting groove 4d and the bolt 6 are arranged coaxially, the limiting slot 4d includes a larger slot width limiting section 4d1 and a smaller slot width connecting section 4d2, the connecting section 4d2 is located in the limiting section 4d1 Between the second plastic gasket 11 and the second plastic gasket 11, a limiting head 11d matching the limiting groove 4d is correspondingly provided on the second plastic gasket 11, and the limiting head 11d is embedded in the limiting groove 4d. By setting the limit head 11d to be embedded in the limit slot 4d, the as...

Embodiment 3

[0058] The structure and principle of the third embodiment are basically the same as those of the first embodiment. The difference is that the connecting structure includes a connecting hole on the inner end surface of the valve seat 1 and a connecting column on the first plastic gasket 10 that matches the connecting hole. There are at least two connecting holes and they are evenly distributed along the circumferential direction. The connecting holes are tapered and the diameter of the connecting holes gradually decreases toward the first plastic gasket 10. The number of connecting posts is the same as the connecting holes and their positions correspond to each other. Embedded in the connecting hole, the tapered connecting column is embedded in the tapered connecting hole, which can also limit the downward movement of the first plastic gasket 10, so that the first plastic gasket 10 and the valve seat 1 Securely and stably fix them together, which improves the service life of the...

Abstract

The invention provides an air valve for a compressor, and belongs to the technical field of machinery. The problem of short service life caused by high separation possibility of a protective layer in a conventional air valve for the compressor is solved. The air valve for the compressor comprises a valve seat, a valve plate and a lift limiter, which are sequentially arranged from top to bottom and are connected through a bolt, wherein a plurality of air inlets are formed in the valve seat; air vents staggered with the air inlets are formed in the valve plate; a first plastic gasket is arranged on the inner end face of the valve seat; springs for tightly pressing the valve plate on the first plastic gasket are arranged at the inner end of the lift limiter; a concavo-convex connecting structure for fixedly connecting the first plastic gasket with the valve seat is arranged between one side of the first plastic gasket and the valve seat; a plurality of through holes I communicated with the air inlets are correspondingly formed in the first plastic gasket, and are staggered with the air vents; a plurality of grooves are formed in the contact surface, in contact with the valve plate, of the other side of the first plastic gasket. The air valve for the compressor has the advantage of long service life.

Description

Technical field [0001] The invention belongs to the technical field of machinery and relates to a compressor gas valve. Background technique [0002] The gas valve is a component installed on the compressor cylinder to control the gas inflow and out. Its performance directly affects the economy and reliability of the compressor. There are many types of compressor valve structures. Among the domestic large and medium-sized compressors, the most widely used ring valve is composed of valve seats, ring valve plates, springs, and lift limiters. The valve plate of the ring valve is arranged between the valve seat and the lift limiter. The valve seat and the lift limiter are connected together by a bolt passing through the center of the valve seat and the lift limiter. There are two annular air flow channels, and each air flow channel on the valve seat is provided with a matching annular valve plate corresponding to it, so that the annular valve plate can be attached to the opening of ...
