Description
Technical field
The utility model relates to a kind of three-way valve, especially relates to a kind of three-way switch valve.
Background technique
Common three-way valve valve body has three mouths, and one enters scene 2.Three-way valve is divided into converging valve and diverter valve by the fluid mode of action, and converging valve has two entrances, behind interflow, from an outlet, flows out.Diverter valve has a fluid input, after shunting, by two fluid outputs, is flowed out.But under many circumstances,, three pipelines need the flow direction (particularly gas circuit) of frequent switch fluids, and are one-in-and-one-outs at every turn, under this specific environment, common three-way valve has obviously been difficult to, and also has some three-way switch valves in prior art, as a kind of, be called as L643X Pneumatic three-way switching valve, mainly by upper valve body, middle valve body, lower valve body, upper sealing, lower seal, flap, cylinder, the compositions such as connecting rod.But it is being manufactured and is using all cumbersome.
Summary of the invention
The utility model is mainly to solve making trouble of the existing three-way switch valve of prior art, and complex structure is used simple not technical problem, provide a kind of simple in structure, manufacture and use all three-way switch valve very easily.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of Novel three-way switch valve, comprise housing, valve seat, spool, in described housing, be provided with three longitudinal stepped valve pockets and be respectively the first valve pocket, the second valve pocket and the 3rd valve pocket, in three valve pockets, correspondence is provided with the first spool respectively, the second spool, the 3rd spool and with its first valve seat one to one, the second valve seat, the 3rd valve seat, described each spool is equipped with seal, described valve seat is provided with the seal ring corresponding with seal, seal is divided into upper cavity and lower chamber by each valve pocket, valve seat and housing are respectively equipped with manhole appendix one and manhole appendix two at the corresponding position of cavity up and down of the first valve pocket, described housing is provided with manhole appendix three at the lower chamber corresponding position of the second valve pocket, the upper cavity of described the first valve pocket and the 3rd valve pocket is connected, the lower chamber of described the second valve pocket and the 3rd valve pocket is connected, the upper cavity of the lower chamber of described the first valve pocket and the second valve pocket is connected, each described spool is provided with lifting control mechanism.Although three-way switch valve described in the utility model is a kind of three mouths that have, only have two mouths of one-in-and-one-out to use, its import and export can be switched at any time, and any two mouthful of combination can one-in-and-one-out.This structure can complete complicated gas circuit and change, and can simplify complicated gas circuit under many circumstances, is conducive to cost-savingly, optimizes gas circuit structure, reduces maintenance cost.It in use mainly comprises following process: move down the first spool, the sealing surface of valve core case and spool is thrown off, manhole appendix one and manhole appendix two are communicated with; Move down the second spool, manhole appendix three and manhole appendix two are communicated with; Move down the 3rd spool, make manhole appendix one and manhole appendix tee joint.
As preferably, described lifting control mechanism comprises:
Be located at the bottom of each valve pocket and the pressure spring between each spool;
Be located at the cam turntable on housing top, cam turntable is provided with the curved surface that can control respectively spool lifting;
Be located at described cam turntable and the steel ball between spool;
Described cam turntable top is connected with a hand knob.
The lifting of ports valve core completes by this lifting control mechanism, and cam turntable is when rotating, and the curved surface on cam turntable can drive one of them steel ball to move down, and drives corresponding spool to move, and pressure spring can automatically reply spool.
The beneficial effect bringing of the present utility model is, solved making trouble of the existing three-way switch valve of prior art, and complex structure is used simple not technical problem, realized a kind of simple in structure, manufacture and use all three-way switch valve very easily.
