Abstract
The utility model relates to a pneumatic valve with a pressure release seam. The pneumatic valve comprises a pipe body and an elastic plug body, wherein the elastic plug body is made of an elastic material; the edge of the elastic plug is fully propped against the pipe wall of the pipe body; and the elastic plug body further comprises a seam, which is formed on the elastic plug body in a penetrating manner. When gas flows to the elastic plug body from the pipe body, and a hole is formed along the junction part of the seam when the impact pressure of the gas is out of resistance of the seam of the elastic plug body, so as to enable the fluid to pass through the elastic plug body, thereby further achieving the purpose of pressure release to the pneumatic valve.
Description
Technical field
The utility model relates to a kind of control valve unit, relates in particular to a kind of air pressure valve with pressure release slot, belongs to engineering component technology field.
Background technique
Fig. 1 is the air pressure valve structural representation of prior art.Its working principle is as follows: when entering 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 be 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, necessaryly provide a kind of more advanced air pressure valve, to overcome described defective of the prior art.
The model utility content
The utility model purpose provides a kind of air pressure valve with pressure release slot with regard to being at the deficiencies in the prior art part.
For achieving the above object, this novel technical solution is finished like this: a kind of air pressure valve with pressure release slot, and it comprises: a tubular body; One is constituted the elasticity cock body by elastic material, and described elasticity cock body edge is resisted against the tube wall of tubular body fully, and described elasticity cock body further comprises a finedraw, and described finedraw is arranged on this elasticity cock body.
Air pressure valve of the present utility model also can be set to: described finedraw be shaped as three fork-shapeds, cross, rice word or other kenel finedraw.
Compared with prior art, the utlity model 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 technical solutions of the utility model are described further:
Fig. 1 is the schematic representation of the air pressure valve structure of prior art.
Fig. 2 is the not schematic representation of pressure release of the air pressure valve with pressure release slot of the present utility model.
Fig. 3 is the not schematic representation of pressure release of elasticity cock body of the present utility model.
Fig. 4 is the schematic representation of elasticity cock body of the present utility model pressure release.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, to the technical solution of the utility model specific description.
See also Fig. 2 to shown in Figure 3, the utility model is a kind of air pressure valve 25 with pressure release slit, mainly forms described 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.Described elasticity cock body 32 edges are resisted against on the tube wall of tubular body fully, its selected material can be silica gel or latex material, therefore, though elasticity cock body 32 is penetrated, but because the elasticity of itself, be not subjected to external force effect or active force when big inadequately, the gas in tubular body 30 still can not flow to the portion 22 (as shown in Figure 3) of losing heart via the pressure release finedraw of elasticity cock body 32.
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 (as shown in Figure 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 utlity model 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.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
