Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of three-way valve, particularly a kind of electric T-shaped valve.
Background technique
Three-way valve is widely used in pipe-line system, for example in water heating system.For convenience three-way valve is switched, adopt electric T-shaped valve usually.
Existing electric T-shaped valve generally includes a valve body and is positioned at the spool of valve body, has an import and two outlets on the valve body, can make fluid discharge through the another one outlet one of them port closing after the spool action.
For example its publication number of Chinese patent CN2512962Y provides a kind of " telescopic electric T-shaped valve ", this three-way valve comprises that an inside is the housing of cavity, have a material feeding mouth and two discharge ports on the housing, also be provided with a reversing sleeve in housing, reversing sleeve links to each other with an Electric actuator.Drive the reversing sleeve swing by Electric actuator in the using process, just can be after the reversing sleeve swing with one of them port closing.Thereby realize the switching of two outlets.
Though above-mentioned electric T-shaped valve can commutate, reversing sleeve is tubular, and size is bigger, and Electric actuator needs bigger power could drive the swing of commutation tube.Simultaneously, because reversing sleeve is tubular, it can not be fully with port closing, that is to say that it does not reach effect with exit seal.Therefore, above-mentioned electric T-shaped valve using effect is not satisfactory.
Existing other electric T-shaped valve also all exists similar problem.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist at prior art, provides a kind of using effect good, constitutionally stable electric T-shaped valve.
The purpose of this utility model can realize by following technical proposal: a kind of electric T-shaped valve, comprise that an inside is the valve body of cavity, have the outlet one, outlet two and the import that communicate with its inner chamber on the valve body, outlet one and outlet two are symmetricly set in the valve body both sides, import is positioned at the valve body middle part, it is characterized in that, axial restraint has a connecting rod on the described valve body, the inner of connecting rod is fixed with when connecting rod rotation energy shutoff outlet one or exports two Sealing, and the outer end of connecting rod is stretched out valve body and is connected with the electric actuator that can drive its rotation.
After the electric actuator drive link was rotated, the Sealing that is positioned at connecting rod the inner was along with together swing.Because Sealing in outlet one and export between two, therefore, when Sealing swing back just can export a shutoff, make that flowing medium can only be by exporting two discharges.In like manner, when the Sealing backswing will export two shutoff, flowing medium can only discharged by outlet one.
Certainly, in the above-mentioned electric actuator drive link rotation process, when Sealing is resisted against outlet one or export on two, electric actuator stops drive link and connecting rod is positioned this position all the time.
In above-mentioned electric T-shaped valve, be provided with seal ring between described connecting rod and the valve body.To sealing between connecting rod and the valve body, avoid flowing medium to leak by seal ring by both joints.
In above-mentioned electric T-shaped valve, described electric actuator is connected on the valve body.
In above-mentioned electric T-shaped valve, described electric actuator comprises a housing, has motor in the housing, and the outer end of above-mentioned connecting rod links to each other with the rotating shaft of motor.
Together rotate by the rotating shaft drivening rod in the motor operation.
In above-mentioned electric T-shaped valve, also have in a tubular form conduit one and conduit two in the described valve body, one end of conduit one is connected with valve seal and communicates with outlet one, one end of conduit two is connected with valve seal and communicates with outlet two, the other end of conduit one and conduit two is provided with in opposite directions, and above-mentioned Sealing is in the gap that has between conduit one and the conduit two and between conduit one and conduit two for the Sealing swing.
Because outlet one distance outlet two is distant, conduit is set contacts with one of them conduit sealing, but also it is relatively good to make that conduit contacts the back sealing with Sealing once not only making Sealing swing smaller angle with conduit two.
In above-mentioned electric T-shaped valve, described conduit one is connected by interference fit with valve body with conduit two.
Adopt this cooperation to make conduit one and conduit two be fixed in the valve body firmly.
In above-mentioned electric T-shaped valve, described valve body inboard is close to outlet one place and has the sealed step of protruding ringwise, and an end of above-mentioned conduit one is connected in sealed step one place.
As can be seen, hole dimension is less than outlet one aperture in the conduit one, and it is more intense that such structure makes that Sealing contacts its sealing of back with conduit one.
In above-mentioned electric T-shaped valve, described valve body inboard is close to outlet two places and has the sealed step of protruding ringwise two, and an end of above-mentioned conduit two is connected in sealed step two places.
Same, hole dimension is less than outlet two apertures in the conduit two, and it is more intense that such structure makes that Sealing contacts its sealing of back with conduit two.
In above-mentioned electric T-shaped valve, described Sealing is in the form of annular discs and made by rubber material.The Sealing that adopts rubber material to make has certain flexibility, can form good sealing when it contacts with conduit one or conduit two.
Compared with prior art, this electric T-shaped valve since in valve body, be provided with export a conduit that communicates one and with the outlet two conduits that communicate two, the smaller angle of Sealing swing just can make flowing medium to be discharged by the another one outlet conduit one or conduit two sealings.As can be seen, the electric actuator drive link is rotated the switching that small angle just can be realized this three-way valve, and practical effect is good, and connecting rod can be because of not rotating premature damage significantly.Simultaneously, because conduit one and conduit two diameters are less than the Sealing size, Sealing can form good sealing after being resisted against on conduit one or the conduit two, has the higher utility of ratio.
