The invention discloses a non-return three-way valve. The non-return three-way valve comprises a valve body and a valve core; the valve core is nested in the cavity of the valve body and in seal fit with the valve body; the valve core comprises a shell and a non-return valve core arranged in the shell; a T-shaped flow channel is arranged in the shell; through holes communicated with the three outlets of the T-shaped flow channel are formed in the valve body; the non-return valve core comprises a plug I, a spring, a rubber head and a plug II, all of which are orderly matched with each other; openings are formed in the end faces of the plug I and the plug II; the non-return valve core is arranged in the straight flow channel of the T-shaped flow channel, and the plug I and the plug II are respectively in seal fit with two through holes in the valve body; under the action of the elastic force of the spring, the rubber head is in seal fit with the plug II. The non-return three-way valve is applicable to liquid and gas pipelines; a plurality of flow path control patterns can be formed due to the cooperation of the rotation of the valve core and the assembly direction of the non-return valve core, in other words, the rubber head can be arranged on one end of the plug I or the plug II to seal the plug I or the plug II, and therefore, the control on different flow directions is realized.
Description
Technical field
The present invention relates to a kind of unidirectional three-way valve, be mainly used in the environmental areas such as flow direction control of gas, liquid.
Background technique
Existing three-way valve, the valve body being communicated with by T shape and shell form, and spool has that three openings are corresponding with shell aperture, and lateral openings is joined a nut, by rotary valve, reaches different connected states.The deficiency of existing three-way valve is: be not with path direction to control function, if will realize this function, need external one-way valve.
Summary of the invention
The object of this invention is to provide a kind of unidirectional three-way valve, described unidirectional three-way valve possesses path direction and controls function, so fast changeable path direction.
Unidirectional three-way valve provided by the present invention, comprises valve body and spool;
Described valve core housing is located in the cavity of described valve body, and and described valve body between for being sealed and matched;
Described spool comprises a housing and is located at the nonreturn valve core in described housing;
In described housing, be provided with a T-shaped runner, described valve body is provided with 3 through holes that outlet is connected with described T-shaped runner;
Described nonreturn valve core comprises plug I, spring, Rubber end and the plug II coordinating successively; On the end face of described plug I and described plug II, be equipped with opening; Described nonreturn valve core is located in the lineal shape runner of described T-shaped runner, and described plug I and described plug II respectively with described valve body on 2 described through holes be sealed and matched; Under the elastic force effect of described spring, described Rubber end and described plug II are for being sealed and matched.
In described unidirectional three-way valve, between described spool and described valve body, by annular groove, match with annular protrusion.
In described unidirectional three-way valve, described annular groove is located on described spool;
Described annular protrusion is located on described valve body, more convenient when both are coordinated.
In described unidirectional three-way valve, described plug I and described plug II are through hole screw.
In described unidirectional three-way valve, between described plug I and described plug II and described through hole, be screw-thread fit, mixing ratio is more convenient.
In described unidirectional three-way valve, the upper opening arranging of described plug I and described plug II is polygonal, as Hexagon, can use like this spanner to assemble.
In unidirectional three-way valve of the present invention, described spring can be selected the resistant materials such as stainless steel, by selecting different elastic force specifications to realize different unidirectional cracking pressures, controls.
Unidirectional three-way valve provided by the invention, can be used for liquid and gas piping; By the rotation of spool and the assembly direction of nonreturn valve core, coordinated and converted out multiple stream control mode, spool can rotate by 360 degree, and Rubber end can be located at one end of plug I or plug II, and shutoff plug I or plug II, realized the control of different fluid direction.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, but the present invention is not limited to following examples.
As Figure 1-Figure 5, for unidirectional three-way valve of the present invention, comprise valve body 1 and spool 2, spool 2 is sheathed in the cavity of valve body 1, and and valve body 1 between for being sealed and matched, in the present embodiment, specifically coordinate in the following way between the two: annular groove 5 is set on spool 2, as shown in Figure 3, on valve body 1, annular protrusion is set, as shown in Figure 2, by realizing annular groove and coordinating of annular protrusion being sealed and matched of valve body 1 and spool 2.
In unidirectional three-way valve of the present invention, spool 2 comprises a housing (in figure mark) and is located at the nonreturn valve core 3 in this housing, as shown in Figure 3.In housing, be provided with a T-shaped runner 4, valve body 1 is provided with the through hole (not marking in figure) being connected with 3 outlets of T-shaped runner 4.As shown in Figure 5, nonreturn valve core 3 comprises plug I31, spring 32, Rubber end 33 and the plug II34 coordinating successively, and plug I31 and plug II34 are through hole screw.As shown in Figure 4, this nonreturn valve core 3 is located in the lineal shape runner of T-shaped runner 4, and plug I31 and plug II34 coordinate by thread seal with 2 through holes on valve body 1 respectively.Under the elastic force effect of spring 32, Rubber end 33 for being sealed and matched, has been realized the shutoff to this runner with plug II34.
Easy to assembly for unidirectional three-way valve, by plug I31 and plug II34, hexagonal opening being set, to assemble with spanner.
In unidirectional three-way valve of the present invention, spring 32 can be selected the resistant materials such as stainless steel, by selecting different elastic force specifications to realize different unidirectional cracking pressures, controls.
In unidirectional three-way valve of the present invention, one-way valve direction can be adjusted according to actual needs, is about to one end that Rubber end 33 is located at plug I31 or plug II34.
While using unidirectional three-way valve of the present invention, first plug I31 is contained in to lineal shape runner one end of spool 2T type runner 4, then need to puts into spring 32, Rubber end 33 according to direction, plug II34 is arranged at the lineal shape runner the other end afterwards; Then spool 2 is pressed in the cavity of valve body 1.Now be connected with injector or pipeline again, by rotary spool 2, can realize corresponding that the T-shaped runner of spool exports with valve body 1.Nonreturn valve core therefore of the present invention is different to be installed (by Rubber end installation direction, realize unidirectional control, can only be open-minded to spring direction from Rubber end, on the contrary sealing; Be in the present invention spool 2 can 360 degree rotation) direction can realize the path direction being communicated with in runner and control.
