Abstract
The invention discloses an air pressure valve with a pressure relief clearance, which comprises a tubular body and an elastic plug body made of elastic material. The edge of the elastic plug body completely props against the wall of the tubular body, the elastic plug body further comprises a thin clearance, and the thin clearance is arranged on the elastic plug body in a penetrating way. When air flows towards the elastic plug body through the tubular body and the impact pressure is higher than the pressure which the thin clearance of the elastic plug body can bear, the intersection part along the thin clearance can be deformed to form holes, so that fluid can flow through the elastic plug body and the purpose of pressure relief can be achieved.
Description
Technical field
The present invention relates to a kind of control valve unit, relate in particular to a kind of air pressure valve, belong to engineering component technology field with pressure release slot.
Background technique
Fig. 1 is the air pressure valve structural representation of existing technology.Its working principle is following: when getting into via suction port as if pressurized gas, its impact force of bringing will push ball 3.If this impact force is during greater than the resist force of spring 41, the ball 3 of originally blocking air input part 200 will no longer continue to block, and this pressurized gas flowed to lose heart portion 22, and pressurized gas are discharged from.
Yet because spring 41 belongs to metal material, the long-term use is easy to generate corrosion, makes spring 41 lose the effect that originally props up ball 3, and then makes whole Decompression valves ineffective.
For avoiding above-mentioned technical problem, necessary a kind of more advanced air pressure valve is provided, to overcome said defective of the prior art.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of air pressure valve with pressure release slot.
Technical solution of the present invention is achieved in that a kind of air pressure valve with pressure release slot, and it comprises: a tubular body; One constitutes the elasticity cock body by elastic material, and said elasticity cock body edge is resisted against the tube wall of tubular body fully, and said elasticity cock body further comprises a finedraw, and said finedraw is arranged on this elasticity cock body.
Air pressure valve of the present invention also can be set to: said finedraw be shaped as three fork-shapeds, cross, rice word or other kenel finedraw.
Compared with prior art, the present invention has following beneficial effect: be equipped with finedraw in the elasticity cock body.When gas flows to the elasticity cock body by tubular body, and the percussive pressure that air-flow brought be can resist greater than the finedraw of elasticity cock body the time, may be deformed to hole along the confluce of finedraw, and makes fluid pass through the elasticity cock body, and then reach the purpose of pressure release.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Fig. 1 is the schematic representation of the air pressure valve structure of existing technology.
Fig. 2 is the not schematic representation of pressure release of the air pressure valve with pressure release slot of the present invention.
Fig. 3 is the not schematic representation of pressure release of elasticity cock body of the present invention.
Fig. 4 is the schematic representation of elasticity cock body of the present invention pressure release.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
See also Fig. 2 to shown in Figure 3; The present invention is a kind of air pressure valve 25 with pressure release slit; Mainly forms said three fork-shapeds, cross, meter word or other kenel finedraw of being shaped as by tubular body 30, elasticity cock body 32 and the pressure release finedraw 34 that is arranged in elasticity cock body 32.Said elasticity cock body 32 edges are resisted against on the tube wall of tubular body fully; Its material of selecting for use can be silica gel or latex material; Therefore, though elasticity cock body 32 penetrated because itself elasticity; Do not receiving external force effect or active force when big inadequately, still can not flow to the portion 22 (shown in accompanying drawing 3) of losing heart via the pressure release finedraw of elasticity cock body 32 at the gas in the tubular body 30.
When gas flows to elasticity cock body 32 via tubular body 30; When the percussive pressure that gas brought can be resisted greater than 34 of the finedraws of elasticity cock body 32; Confluce along finedraw 34 may be deformed to hole 36 (shown in accompanying drawing 4), and makes fluid pass through elasticity cock body 32 and flow to the portion 22 of losing heart along the direction of arrow 38.
Compared with prior art, the present invention has following beneficial effect: be equipped with finedraw in the elasticity cock body.When gas flows to the elasticity cock body by tubular body, and the percussive pressure that air-flow brought be can resist greater than the finedraw of elasticity cock body the time, may be deformed to hole along the confluce of finedraw, and makes fluid pass through the elasticity cock body, and then reach the purpose of pressure release.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
