Abstract
The utility model discloses a one way valve which has the technical scheme that the one way valve comprises a valve body, wherein, a valve cavity is arranged in the valve body; an elastic valve plate capable of sealing the end of the valve cavity in one way is fixedly connected with the outside of one end of the valve cavity; the valve body is made of soft elastic materials; and the elastic valve plate and the valve body are integrally formed. The utility model aims to overcome the defects of the prior art and provide a one way valve which is made of soft elastic materials and has the advantages of simple structure, convenient installation and low manufacture cost. The one way valve is made of soft elastic materials and has the advantages of simple structure, convenient installation and low manufacture cost. The valve body, the valve plate and a sealing ring are in integral injection molding and without assembly; when the one way valve is used, the installation is convenient.
Description
[technical field]
The utility model relates to a kind of one-way valve.
[background technique]
One-way valve is used very extensive in sealed product, one-way valve makes sealing become very convenient, yet existing one-way valve all is that a step hole is set in valve pocket, in the step sky ball is set, utilize ball and cooperating of step hole to realize the unidirectional conducting of convection cell, the complicated fabricating cost height of this type of one-way valve structures needs configuration seal ring in addition, installs inconvenient, be difficult to seal, need a kind of simple in structurely, easy for installation, the one-way valve that fabricating cost is low is used for vast sealed product.
[model utility content]
The utility model purpose is to have overcome the deficiencies in the prior art, provide a kind of by soft elastic material make simple in structure, easy for installation, the one-way valve that fabricating cost is low.
The utility model is achieved through the following technical solutions:
A kind of one-way valve, it is characterized in that including valve body, be provided with valve pocket in the described valve body, the end outside of described valve pocket is fixedly connected with can be with the feather valve door-plate of this end unidirectional blocking of valve pocket, described valve body is made by soft elastic material, and described feather valve door-plate and valve body are formed in one.
Aforesaid one-way valve is characterized in that a direction between described valve body and the feather valve door-plate is provided with one section ventilation slit of opening the back conducting in feather valve door-plate elasticity.
Aforesaid one-way valve is characterized in that the outside of described valve body is provided with seal ring.
Aforesaid one-way valve is characterized in that described valve body made by rubber.
Aforesaid one-way valve is characterized in that described valve body is cylindrical.
Compared with prior art, the utility model has following advantage:
1, the utility model by soft elastic material make simple in structure, easy for installation, fabricating cost is low;
2, the utility model valve body, valve plates, seal ring can be integrated injection molding and need not assembling, and be easy for installation during use.

[embodiment]
A kind of one-way valve, comprise the valve body of making by soft elastic material 1, being provided with in the described valve body 1 can be for the valve pocket 101 of fluid flow, and an end of described valve pocket 101 is an opening end, and the other end outside is fixedly connected with can be with the feather valve door-plate 102 of valve pocket 101 these end unidirectional blockings.Described feather valve door-plate 102 is formed in one with valve body 1, and according to the described one-way valve of claim 1, a direction between described valve body 1 and the feather valve door-plate 102 is provided with one section ventilation slit 105 of opening the back conducting in feather valve door-plate 102 elasticity.The outside of described valve body 1 is provided with and valve body 1 integrated seal ring 103.Described valve body 1 is cylindrical for what made by rubber.
In the using process, after one-way valve being installed to the relevant position of sealed product, the seal ring 103 of one-way valve forms sealing with the one-way valve mounting hole hole wall of sealed product, when the pressure of opening end one side is higher than the pressure of sealed end one side, high-pressure liquid flows into from the one-way valve opening end, the sealing elastic force that utilizes pressure reduction to overcome valve plates 102 opens valve plates 102 and forms ventilation slit 105, and fluid flows out from ventilation slit 105.When the pressure of opening end one side was lower than the pressure of sealed end one side, valve plates 102 was closed under sealing elastic force and differential pressure action.
