Include a stage portion radially-inwardly protruded into, the spring base is fixedly connected with one end of the valve body, after connection, the spring base and
The stage portion forms an accommodating space, and the spring and ball sealer are placed in the accommodating space, and the ball sealer is by the bullet
The tension force effect of spring is resisted against the stage portion, the stage portion towards the side of the ball sealer be a circular conical surface；It is described to lead
Set is a hollow cylinder, and the guide sleeve riveting connects the other end of the valve body.
According to embedded one-way valve described in the utility model embodiment, the outer surface of the valve body includes several barbs
Structure.
The utility model improves existing check valve, designs a inheriting tradition check valve from structure and principle
Function, structure is simpler, is designed to built-in, is placed in inside host, and occupied space is saved, and assembly is simply easily assembled unidirectional
Valve；The reaction of the check valve to be looked for novelty simultaneously is rapider, and failure rate is low, and properties of product are more reliable, longer life expectancy.
Due to the technical characteristic more than using so that the utility model have the following advantages compared with the prior art and
Good effect:
The first, the application one-way valve structures are simple, compact, are designed to built-in, are placed in inside host；
The second, the mounting means of the application check valve abandons the threaded connection of conventional through type and right-angle type, first will be single
It is packed into inside host to valve, by external force riveting, deforms the specific dimensions of valve, be interference fitted after deformation with host；
Third, the application improve the assembling speed of host, and size can improve product with arbitrary size, entire air-channel system
Reliability and service life.
Certainly, any one specific embodiment for implementing the content of the present invention, might not have all of the above simultaneously
Technical effect.
Detailed description of the invention
Fig. 1 is the cut-away diagram that the application check valve connects host；
Fig. 2 is the cut-away diagram of the application check valve；
Fig. 3 is the cut-away diagram before the application check valve riveting host.
Specific embodiment
Below in conjunction with attached drawing, the utility model is illustrated.
Referring to FIG. 1, a kind of embedded one-way valve assembly connection host 7, as shown, main through-hole is opened up on host 7,
For controlling the circulation of gas or liquid, check valve is connected by the way of riveting with main through-hole；It please also refer to Fig. 2, this Shen
Embedded one-way valve please includes a spring base 1, a spring 2, a ball sealer 3, a valve body 4 and a guide sleeve 5, wherein the bullet
Spring abutment 1 is a cup body shape, and the opening of the spring base 1 is flared out, and the bottom of a cup face of the spring base 1 opens up through-hole, through-hole
Size be unlikely to influence spring 2 work；The valve body 4 is a hollow cylindrical body, the inner wall of the valve body 4 include one it is radial to
The stage portion inside protruded into；The opening of the spring base 1 is fixedly connected with one end of the valve body 4, and the mode of connection can be with riveting
Or riveting process, after connection, the spring base 1 and the stage portion form an accommodating space, the spring 2 and ball sealer 3
It is placed in the accommodating space, the ball sealer 3 is resisted against the stage portion, the stage portion by the tension force effect of the spring 2
It is a circular conical surface towards the side of the ball sealer 3, circular conical surface has been the critical size that check valve plays good sealing function, and angle must
It must control at 120 ± 5 degree, effect is best under this angle；The guide sleeve 5 is a hollow cylinder, 5 riveting of the guide sleeve connection
The other end of the valve body 4.
The application is suitble in the pipeline of microminiature, it is desirable that check valve reaction is rapider, therefore the requirement of spring force is smaller
It is better, it is therefore an objective to ball sealer 3 to be fixed.As long as being greater than 3 gravity of ball sealer in principle.In the condition for meeting basis
Under, spring force is smaller, and unidirectional valve opening pressure is just smaller, and check valve is sensitiveer.
The application embedded one-way valve and 7 catenation principle of host: the check valve of the application has a guide sleeve 5, this part
Producing is the assembly connected with pre- riveting, as long as shown in figure 3, guaranteeing that the part is not fallen off.Equal check valves are packed into host 7
In, riveting is carried out to guide sleeve 5, guide sleeve 5 is squeezed into inside valve body 4, keeps the support of 4 diameter of valve body big, the external diameter of original valve and host master
The gap of through-hole is with regard to smaller, and valve body 4 is just closely connect with the main through-hole of host completely after supportting greatly, as shown in Figure 1.In addition,
It include several overhead structures 6 in the outer surface of the valve body 4, to prevent check valve from falling off, as shown in Fig. 2, there is 4 barb knots
Structure 6, but cannot be used to limit the application, it is mostly several or few several, it all should be this as long as can achieve the purpose that prevent from falling off
The protection scope of application.
Then illustrate the working principle of the application check valve: as shown in Fig. 2, when fluid media (medium) enters from the end A, Fluid pressure
Overcome spring force, push ball sealer 3 open, fluid is flowed out from the end B, and the place being arbitrarily designated is flowed to by pipeline；As long as Fluid pressure
Greater than spring force, fluid is just unblocked.When the end A stops providing fluid, the end B ball sealer 3 is multiple at once under spring force
Position prevents fluid reflux.
The mentality of designing of the application is that the size of valve body outer diameter and the main through-hole of host must be by certain fit dimension.It leads
Before covering 5 rivetings, influence after riveting on the size of valve body outer diameter must be by accurate calculating, i.e. riveting front valve shell outer diameter must be small
In the main through-hole of host, riveting rear valve body outer diameter has to be larger than the main through-hole of host.Moreover, guide sleeve 5 and the hardness of valve body 4 have been had to
Difference of hardness, is unable to that hardness is identical, and otherwise part deforms mutually will lead to failure.The application is the study found that 5 hardness of guide sleeve must be big
In 4 certain degree of hardness of valve body, in order to can smoothly strut valve body 4 to specified size.Valve body 4 requires enough strong on material
Degree and certain toughness, in order to the main through-hole of host can be permanently affixed to, there is direct relation in the service life with main body.
Due to the technical characteristic more than using so that the utility model have the following advantages compared with the prior art and
Good effect:
The first, the application one-way valve structures are simple, compact, are designed to built-in, are placed in inside host；
The second, the mounting means of the application check valve abandons the threaded connection of conventional through type and right-angle type, first will be single
It is packed into inside host to valve, by external force riveting, deforms the specific dimensions of valve, be interference fitted after deformation with host；
Third, the application improve the assembling speed of host, and size can improve product with arbitrary size, entire air-channel system
Reliability and service life.
Disclosed above is only several specific embodiments of the utility model, but the utility model is not limited to this, is appointed
What what those skilled in the art can think variation, should all fall within the protection scope of the present utility model.
