Description
Technical field
The utility model belongs to valve technology field, is related to a kind of three-way valve core.
Background technology
Triple valve is one of conventional valve, and it has three mouths, may be configured as Two In and One Out or One In and Two Out, with full
The demand of the different use environments of foot.When carrying out water route selection often through rotational handle with the valve core rotation in moving valve, from
And control the break-make in water route flow.
For example, people devise a kind of solar water heater threeway controlling valve and have applied for Chinese patent (its Application No.：
200720038821.X；Its notification number is：CN201045421Y), the threeway controlling valve includes bonnet, valve body, valve element and knob,
It is provided with valve body and goes out with the cold water water inlet interface of the T-shaped arrangement of hollow intracavity inter-connection, cold water water outlet mouthpiece and hot water
Water interface, valve element is installed in the inner chamber of valve body, open up that connection communicates on valve element into the cold water inlet hole road of Y shape arrangement, cold water
Water outlet duct and hot water effluent duct, the bypass communicated therewith is offered on the left of the entrance in the cold water inlet hole road of valve element and is slitted
Groove.In use, by operation knob with the valve core rotation in moving valve so that the duct on valve element is connected with the interface on valve body
It is logical that water outlet can be achieved.
But in the threeway controlling valve, three T-shaped distributions of interface on valve body, and three Y-shaped point of ducts in valve element
Cloth so that both can not correspond to completely, although so that the valve element can easily realize the control of one-in-and-one-out when in use,
It is, in order to realize the One In and Two Out of valve body, it is necessary to open up a bypass slot in addition on valve element, manufacturing procedure increase, and bypass
Slot sets up the ring packing for being unfavorable for the port perimeter.
The content of the invention
The purpose of this utility model is in view of the above-mentioned problems existing in the prior art, it is proposed that a kind of three-way valve core,
The technical problem of solution is how to make the processing of three-way valve core more easily while improve sealing effectiveness.
The purpose of this utility model can be realized by following technical proposal：
A kind of three-way valve core, including main body, the top of the main body have the connection for being used for being connected with valve rod or handle
Portion, the sidepiece of the main body offer the flowing hole passed through for medium, it is characterised in that the flowing hole, which includes running through, to be opened up
In the through hole one and through hole two of body side, the through hole one is opened up with the intersection of through hole two and both are connected, the main body side
Sealing gasket is connected with wall at the port of above-mentioned one end of through hole one, the sealing gasket covers the port of above-mentioned through hole one and will
The port blocks.
During this three-way valve core is in use, be equally fitted into the valve body with three interfaces, opened up in the main body of three-way valve core logical
Hole one and through hole two, altogether with four ports, after a port that through hole one is blocked using sealing gasket, remaining three ports.It is logical
Cross operation handle and drive body rotation, when three ports of main body are connected with three interfaces on valve body respectively, can be achieved
One In and Two Out or Two In and One Out, after body rotation, when only two of which port is connected with two interfaces on valve body, i.e.,
One-in-and-one-out can be achieved, another interface blocks.In this control process, when needing to realize one-in-and-one-out, the position of sealing gasket
Put and faced with the inner end positions of one of interface on valve body, any one in other three ports of valve element main body and valve
When the inlet of body is connected, liquid medium enters in the main body of valve element, can be from inside to outside to being connected at through hole Single port
Sealing gasket applies outside active force so that the outside tight abutment of sealing gasket further enhances sealing in the inner of valve body interface
The sealing effectiveness to valve body interface is padded, i.e., improves sealing effectiveness using hydraulic pressure.Meanwhile this three-way valve core directly passes through in sidepiece
Wear and open up through hole one and through hole two, the problem of machining accuracy during without considering to open up blind hole, difficulty of processing is low, facilitate plus
Work.
In above-mentioned three-way valve core, there is recessed groove positioned at the above-mentioned end of through hole one in the main body wall,
Above-mentioned sealing gasket part is caught in the groove and the lateral wall of sealing gasket protrudes from the lateral wall of aforementioned body, above-mentioned through hole one
One end is opened in the bottom of groove.Sealing gasket is caught in groove, is attached without other other connected modes, processing and
Install more convenient, the lateral surface of main body is protruded from the outside of sealing gasket so that the lateral wall of sealing gasket can be preferably on valve body
The inner port of interface is sealed, lift-off seal effect.Because sealing gasket seals, rubber, silica gel, TPV can be typically used
Be made etc. material, and main body is often made of engineering plastics or metal material, then the material of sealing gasket relative to main body material
Matter is softer, so relatively low for the requirement on machining accuracy of the size of groove.
In above-mentioned three-way valve core, the lateral surface of the sealing gasket is arc surface.Because week can occur in valve body for main body
To rotation, sealing gasket lateral wall is that arc surface may be such that sealing gasket is more smooth with body rotation, can also enable sealing gasket and valve
Sealing is better achieved in internal wall.
In above-mentioned three-way valve core, the bottom of the groove is further opened with recessed neck, has on the sealing gasket
The Access Division of protrusion, the Access Division are correspondingly caught in above-mentioned neck.Open up neck again in groove, sealing gasket can be facilitated
Install and fixed, meanwhile, sealing gasket part is snapped onto to the bottom of groove, also can make the sealing effectiveness of sealing gasket more preferably.
In above-mentioned three-way valve core, the bottom surface of the groove is arc surface, above-mentioned sealing gasket towards groove floor one
Side has the abutment face of circular arc, and the abutment face and the bottom surface of above-mentioned groove mutually recline.Because body cavity side wall is generally justified
Cambered surface, then groove floor is also configured as arc surface, sealing gasket stress between groove and valve interior wall can be made evenly, to ensure
Sealing effectiveness.
In above-mentioned three-way valve core, the through hole one and through hole two are arranged in a mutually vertical manner.Three on general valve body connect
Mouth can be arranged to T-shaped distribution, and through hole one and through hole two are vertical setting during can making the use of this three-way valve core, often rotate 90
A kind of switching for passing in and out water state can be achieved in degree, and using more convenient, operation is more directly perceived.
In above-mentioned three-way valve core, the main body is cylindrical or spherical, and above-mentioned through hole one and through hole two are along main body
Radial direction open up.The through hole one and through hole two radially opened up can make the structure of whole valve element more stable.
Compared with prior art, for this three-way valve core directly in sidepiece through through hole one and through hole two is opened up, processing is more square
Just, and in the port of the one end of through hole one sealing gasket of closure port is set, make use of the effect of valve core inside hydraulic pressure close to be lifted
The packing sealing effectiveness inner to valve body interface, and the fit system of groove and sealing gasket causes opening up and sealing gasket for groove
Assembling is more convenient.
