It is equipped with opening on the end face of head ii；Described nonreturn valve core is in the linear runner of described t type runner, and described plug i
Coordinate with 2 described through hole sealings on described valve body respectively with described plug ii；Under the elastic force of described spring acts on, described
Rubber end and described plug ii are sealing cooperation.
In described unidirectional three-way valve, matched with annular protrusion by annular groove between described valve element and described valve body
Close.
In described unidirectional three-way valve, described annular groove is on described valve element；
Described annular protrusion, on described valve body, makes both more convenient when being coordinated.
In described unidirectional three-way valve, described plug i and described plug ii are through hole screw.
In described unidirectional three-way valve, it is screw thread cooperation between described plug i and described plug ii and described through hole, joins
Composition and division in a proportion is more convenient.
In described unidirectional three-way valve, on described plug i and described plug ii, the opening of setting is polygon, such as six sides
Shape, so can be assembled using spanner.
In unidirectional three-way valve of the present invention, described spring may be selected the resistant materials such as rustless steel, by selecting different elastic force
Specification is realized different unidirectional Opening pressures and is controlled.
The unidirectional three-way valve that the present invention provides, can be used for liquid and gas piping；By rotation and the nonreturn valve core of valve element
Assembly direction coordinating change to swap out multiple stream control modes, that is, valve element can 360 degree of rotations, Rubber end can located at plug i or
One end of plug ii, that is, closure plug i or plug ii is it is achieved that the control in different fluid direction.

Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings, but the invention is not limited in following examples.
As Figure 1-Figure 5, it is unidirectional three-way valve of the present invention, including valve body 1 and valve element 2, valve element 2 is sheathed on valve body 1
In cavity, and it is sealing cooperation and valve body 1 between, in the present embodiment, between the two particular by following manner cooperation:
On valve element 2 arrange annular groove 5, as shown in figure 3, on valve body 1 arrange annular protrusion, as shown in Fig. 2 by annular groove with
The sealing cooperation of valve body 1 and valve element 2 is realized in the cooperation of annular protrusion.
In unidirectional three-way valve of the present invention, valve element 2 includes a housing (in figure is not marked) and the check valve in this housing
Core 3, as shown in Figure 3.It is provided with a t type runner 4 in housing, valve body 1 is provided with and is connected with 3 outlets of t type runner 4
Through hole (in figure is not marked).As shown in figure 5, nonreturn valve core 3 includes plug i31, spring 32, Rubber end 33 and the plug coordinating successively
Ii34, plug i31 and plug ii34 are through hole screw.As shown in figure 4, this nonreturn valve core 3 is located at the linear of t type runner 4
In runner, and plug i31 and plug ii34 passes through threaded sealing fit with 2 through holes on valve body 1 respectively.Bullet in spring 32
Under power effect, Rubber end 33 and plug ii34 are sealing cooperation, then achieve the closure to this runner.
Easy to assembly for unidirectional three-way valve, on plug i31 and plug ii34, hexagonal opening will be set, to use
Spanner is assembled.
In unidirectional three-way valve of the present invention, spring 32 may be selected the resistant materials such as rustless steel, by selecting different elastic force rule
Lattice are realized different unidirectional Opening pressures and are controlled.
In unidirectional three-way valve of the present invention, check valve direction can be adjusted according to actual needs, will Rubber end 33 located at
Plug i31 or one end of plug ii34.
During using unidirectional three-way valve of the present invention, first plug i31 is contained in the linear runner one of valve element 2t type runner 4
End, needs to put into spring 32, Rubber end 33 further according to direction, afterwards plug ii34 is arranged in the linear runner other end；
Then valve element 2 is pressed in the cavity of valve body 1.Now it is connected with syringe or pipeline, valve element be can achieve by rotary spool 2 again
T type runner is corresponding with what valve body 1 exported.The different installation of nonreturn valve core therefore of the present invention (is realized by Rubber end installation direction
Unidirectionally controlled, that is, can only be open-minded to spring direction from Rubber end, on the contrary closing；I.e. in the present invention valve element 2 can 360 degree rotation) side
Control to the path direction in achievable connection runner.
