Abstract
The utility model discloses a one-way valve core of an air compressor, which is provided with a cup-shaped main body. Compared with the prior art, the one-way valve core is characterized in that the front end of the cup-shaped main body is provided with a soft working surface, and the soft working surface is embedded in the front end of the cup-shaped main body. The one-way valve core has the advantages of improving sealing property, reducing working noise, being more durable, being long in service life and reducing possibility that a motor is burnt.
Description
Technical field
The utility model relates to the air compressor component in the mechanical device, is a kind of spool that matching used one-way valve or unloading one-way valve etc. use on the air compressor that supplies.
Background technique
Air compressor is an a kind of purposes standard equipment very widely, can both see its trace in all trades and professions, in national economy, is bringing into play important effect.Existing air compressor is structurally similar, and is especially also basic identical on accessory, like the one-way valve of general urgent employing at present or have the discharging type one-way valve of off-load effect, uses the cup-shaped spool in these one-way valves or the unloading valve mostly.These cup-shaped spools are processed by a kind of material basically, like nonferrous materialss such as nylon or PTFE.Because what use is harder material, certain noise is arranged during work, and sealing is poor, cost is also higher relatively, and working life is also not ideal enough.
Summary of the invention
The purpose of the utility model provides a kind of good airproof performance, non-return valve for air compressor spool that operating noise is low, more durable.
The technical solution of the utility model is: a kind of non-return valve for air compressor spool, a cup shaped body is arranged, and its difference with the prior art part is: the front end in cup shaped body has a soft working surface, and soft working surface is flush-mounted in the front end of cup shaped body.
The front side end in cup shaped body described in the utility model has annular groove, and soft ring bodies is flush-mounted in the annular groove.Soft working surface described in the utility model is an oil resistant, wear-resisting, high temperature resistant ring-type body.
The utility model has the advantages that: improve the sealing of spool, reduced operating noise, more high temperature resistant, durable, long service life, service behaviour is better, reduces the situation that motor burns out.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of a kind of non-return valve for air compressor spool of the utility model.
Embodiment
Accompanying drawing has been described an embodiment of the utility model.A cup shaped body 1 is wherein arranged, at the front end of cup shaped body 1 a rubber ring bodies 2 as soft working surface is arranged, rubber ring bodies 2 is flush-mounted in the front end of cup shaped body 1.Front side end in cup shaped body 1 has annular groove, and rubber ring bodies 2 is flush-mounted in the annular groove.
The utility model can also adopt other suitable structural type, only is positioned at the front end of main body 1 like rubber ring bodies 2; Or adopt acyclic rubber body; Perhaps adopt other suitable material etc.
The above is merely the embodiment of the utility model, but the protection domain of the utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
Claims (2)
1. a non-return valve for air compressor spool has a cup shaped body, and its difference with the prior art part is: the front end in cup shaped body has a soft working surface, and soft working surface is flush-mounted in the front end of cup shaped body.
2. non-return valve for air compressor spool according to claim 1 is characterized in that: the front side end in cup shaped body has annular groove, and soft ring bodies is flush-mounted in the annular groove.
