Abstract
The utility model discloses a pipeline joint having a non-return function, which comprises a joint body. The two ends of the joint body are respectively provided with a liquid inlet interface and a liquid outlet interface. A non-return valve unit is arranged in the core space of the joint body. According to the utility model, due to the adoption of the non-return valve unit arranged in the core space of the pipeline joint, the liquid backflow phenomenon inside the pipeline of a liquid processing system is effectively prevented. The pipeline joint having a non-return function has the advantages of simple structure, low cost and convenient installation. Through arranging elastic sealing gaskets on the outer walls of the liquid inlet interface and the liquid outlet interface of the pipeline joint, the sealing performance between the pipeline joint and a conveying pipeline is improved and the liquid leakage is effectively prevented.
Description
Technical field
The utility model relates to a kind of adapter piece, especially a kind of adapter piece that is used for two conveyance conduits of connection of liquid processing system.
Background technique
In existing liquid processing system, pipe connector is the middle transition part that is used to connect two conveyance conduits, and existing pipe connector comprises body, and the interface that is used to connect two conveyance conduits that is separately positioned on the body two ends.
Because the particularity of liquid processing system, the inner liquid of conveyance conduit need keep the flow direction of fixing, and promptly can only be to flow to another conveyance conduit from a conveyance conduit.And when conveyance conduit takes place to stop up be, be easy to produce liquid refluence phenomenon, in order to address this problem, just need on liquid processing system, install multiple baroque control system additional.Like this, not only influence the installation efficiency of liquid processing system, and improved the cost of production of liquid processing system greatly.
Summary of the invention
Goal of the invention: the purpose of the utility model provides a kind of pipe connector with check function, can effectively prevent the liquid refluence phenomenon of pipe interior in the liquid processing system.
In order to solve the problems of the technologies described above, the utility model has adopted following technological scheme:
A kind of pipe connector with check function comprises body, and the two ends of said body are respectively equipped with the feed liquor interface and go out liquid interface, are provided with check valve apparatus in chamber body.
Further, said check valve apparatus comprises valve rod, and an end of said valve rod is connected with the plug that is arranged on the feed liquor jointing, and the external diameter of said plug is greater than the internal diameter of feed liquor interface, and the other end of valve rod passes the guide sleeve that is arranged on the fluid jointing.
Further; The external diameter of said feed liquor interface and the external diameter that goes out liquid interface are slightly less than the internal diameter of conveyance conduit; Be respectively equipped with first annular groove and second annular groove at feed liquor interface and the outer wall that goes out liquid interface; In first annular groove He in second annular groove, be respectively equipped with first elastic sealing gasket and second elastic sealing gasket, the external diameter of said first elastic sealing gasket and second elastic sealing gasket is slightly larger than the internal diameter of conveyance conduit.
Further, be provided with the 3rd elastic sealing gasket between said feed liquor interface and the plug.
Beneficial effect: the utility model can effectively prevent the liquid refluence phenomenon of pipe interior in the liquid processing system through adding check valve apparatus at the pipe connector inner chamber, and simple in structure, old cheap, easy for installation; Feed liquor interface through at pipe connector is provided with elastic sealing gasket with the outer wall that goes out liquid interface, has improved the sealability of pipe connector and conveyance conduit, effectively prevents liquid leakage.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the on state schematic representation of the utility model.
Fig. 3 is the cut-off state schematic representation of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done explanation further.
Like Fig. 1,2 and 3 said, the pipe connector with check function of the utility model comprises body 1, is respectively equipped with feed liquor interface 2 at the two ends of body 1 and goes out liquid interface 3, is provided with flange 12 at the middle part of body 1, is provided with check valve apparatus at the inner chamber of body 1.The utility model respectively through feed liquor interface 2 with go out liquid interface 3 and be connected and connect first conveyance conduit 13 and second conveyance conduit 14 respectively; Flange 12 separates first conveyance conduit 13 and second conveyance conduit 14, and check valve apparatus prevents liquid return to the first conveyance conduit 13 of second conveyance conduit, 14 inside.
The external diameter of feed liquor interface 2 is slightly less than the internal diameter of first conveyance conduit 13 and the internal diameter of first conveyance conduit 13 respectively with the external diameter that goes out liquid interface 3; Be respectively equipped with first annular groove 7 and second annular groove 8 at feed liquor interface 2 and the outer wall that goes out liquid interface 3; In first annular groove 7 He in second annular groove 8, be respectively equipped with first elastic sealing gasket 9 and second elastic sealing gasket 10; The external diameter of said first elastic sealing gasket 9 is slightly larger than the internal diameter of first conveyance conduit 13, and the external diameter of said second elastic sealing gasket 10 is slightly larger than the internal diameter of second conveyance conduit 14.When feed liquor interface 2 when going out liquid interface 3 and be connected first conveyance conduit 13 and second conveyance conduit 14 respectively, first elastic sealing gasket 9 and second elastic sealing gasket 10 receive the inwall extruding of first conveyance conduit 13 and second conveyance conduit 14 respectively, prevent liquid leakage.
Check valve apparatus comprises valve rod 6, and an end of said valve rod 6 is connected with the plug 4 that is arranged on feed liquor interface 2 places, and the external diameter of said plug 4 is greater than the internal diameter of feed liquor interface 2, and the other end of valve rod 6 passes the guide sleeve 5 that is arranged on out liquid interface 3 places.In order to improve the sealability between feed liquor interface 2 and the plug 4, between the outer wall of the inboard of feed liquor interface 2 and plug 4, be provided with the 3rd elastic sealing gasket 11.
When liquid flowed to second conveyance conduit 14 through first conveyance conduit 13, plug 4 was moved to the left under the hydraulic shock effect, and plug 4 separates with the 3rd elastic sealing gasket 13, and check valve apparatus is on state.
When liquid flowed to first conveyance conduit 13 through second conveyance conduit 14, plug 4 moved right under the hydraulic shock effect, and plug 4 and the 3rd elastic sealing gasket 13 are fitted, and check valve apparatus is cut-off state.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
