Be arranged in joint body 1 and close to the arrival end, the elastic component 4 be located at the piston component and the connection component it
Between.
When the outlet end of the joint body 1, connection is stored with the equipment of medium, medium in equipment via it is described go out
Mouth end enters in joint body 1, pushes the piston component mobile to arrival end and the elastic component 4 is driven to be compressed to the work
Plug assembly and the connection component, which are formed, to be sealed.
Specifically, the joint body 1 is in bending, including an arrival end and one outlet end, outlet end connection is set
Standby, arrival end can connect external hose 10.
With reference to Fig. 2, the connection component includes double outer tooth connectors 6 of inner hollow and both ends open, and double outer teeth connect
First 6 one end is placed in the arrival end of the joint body 1, and it is matched to be socketed one outside the other end of double outer tooth connectors 6
Nut 7, external hose 10 is socketed between double outer tooth connector 6 and nut 7.
In order to guarantee to seal, in the present embodiment, connect on the periphery wall of double outer tooth connectors 6 along perpendicular to double outer teeth
First 6 length direction has been provided projectingly annular convex platform, and the left part that double outer tooth connectors 6 are located at the annular convex platform is socketed on
It is connect in the joint body 1, positioned at the right part of the annular convex platform with the nut 7, and annular convex platform connects with described
Gasket 8 is respectively arranged between head ontology 1 and the nut 7.
Specifically, the piston component includes the piston rod 2 and the first O-shaped sealing ring 3 of T-type, first sealing
Circle 3 is socketed on the piston rod 2 close to one end of the arrival end, and the described one end of piston rod 2 far from the arrival end is along vertical
Directly extend limiting section in 2 length direction of piston rod, the elastic component 4 is located at the limiting section towards the arrival end
Side.
In the present embodiment, the elastic component 4 is spring, and the spring is socketed on outside the piston rod 2.It is understood that
It is that spring can also both be fixed the limiting section of its left end and piston rod 2, right end freedom with the free on-fixed in both ends
On-fixed can also fix the end face of its right end and double outer tooth connectors 6, the free on-fixed in left end, it might even be possible to by left and right end

It must be to bottom be screwed in the prior art, so as to arbitrarily adjust the rotational angle for connecting outer tooth 11, so check valve really
Adjustable angle.
The principle of the present invention is as follows: as shown in A1 arrow in Fig. 2, when the air pressure of the inverse direction in equipment, steam,
When the media such as oil flow into 1 inside of joint body, piston rod 2 is pushed to the right, push the spring is compressed in the movement of piston rod 2, most
Make a sealing ring 3 and double outer tooth connectors 6 form sealing eventually, achievees the effect that reversely to seal；As shown in A2 arrow in Fig. 2, when
When the media such as positive air pressure, steam, oil flow to joint body 1, due to there is the reset response of compressed spring, so positive medium
Conducting only needs minimum power that can be connected, and general forward direction cracking pressure only needs 3~5KPa normally-open.
In conclusion implementing minute-pressure open check valve connector of the invention, have the advantages that the present invention in connector
Intrinsic close incoming-side location piston component and elastic component, elastic component work as institute between piston component and connection component
The outlet end connection of joint body is stated when being stored with the equipment of medium, the medium in equipment enters connector sheet via the outlet end
In vivo, it pushes piston component mobile to arrival end and elastic component is driven to be compressed to piston component and connection component formation sealing, from
And achieve the effect that reversely to seal；When arrival end has medium to flow to joint body, since the reset force of flexible part exists, institute
The medium conducting flowed into forward direction only needs minimum power that can be connected.
The embodiment of the present invention is described with above attached drawing, but the invention is not limited to above-mentioned specific
Embodiment, the above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art
Under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, it can also make very much
Form, all of these belong to the protection of the present invention.
