Abstract
The utility model relates to a hand-operated valve of three-way, which is improved on the basis of the existing valve and the faucet; the lower end of a valve body is provided with a water inlet, and the right and left ends are respectively provided with a water outlet; the plug cock adopts the cone structure; a port is respectively arranged at the lower part and the side wall of the plug cock; the top is sealed, and the middle part is a cavity. The open and close of the three-way valve are controlled by the rotation of the plug cock during use; in order to keep the good contact of the plug cock and the sealing ring and ensure the sealing performance of the three-way valve, a spring is installed between the plug cock and a valve spindle, and is used for regulating the contact force between the plug cock and the sealing ring.
Description
Manual three-way valve described in the utility model is suitable for using as three-way valve or water tap in various pipelines.
Existing stop valve or water tap be to solve seepy question, all are to adopt upper opening, filledly at the valve rod place compress switch direction employing spiral lift with lid.The shortcoming of this structure is that the working life of valve or water tap is short, usually the pressure of excessive or water makes seal ring damage greatly because the operator exerts oneself, cause leakage phenomenon, change very inconvenient, though ball valve, gate valve and stopcock have alleviated the degree that leak at the valve rod place, but use once leaking to be difficult to repair, and can not be developed to three-way valve.In addition, various valves that use at present and water tap adopt the water outlet type of intake on one side, if when needing two to use water spot, just must two valves of installation or water tap, and must increase and material such as connect in the threeway, use is inconvenience also.
The purpose of this utility model is a kind of good seal performance of design, and is simple in structure, the convenient and manual three-way valve that can be simultaneously uses as two valves or water tap of working service.
Manual three-way valve described in the utility model is to improve to form on the basis of former valve and water tap, and it is by valve body (01), seal ring (02), packing ring (03), handle (04), nut (05), valve rod (06), valve gap (07), spring (08), cock (09) is formed.Cock is positioned at the valve body lumen, and the upper end links to each other with handle by valve rod, and handle is fixed with nut, and the lower end contacts with seal ring, and valve body lower end is a water intake, about the end all as water outlet, between cock and valve gap, spring is housed.
In order to improve the sealability of three-way valve, cock is designed to cone, top seal, and the middle part is a cavity, and bottom opening is as water intake, and sidewall opening is as water outlet, and water outlet preferably is rectangle, and opens and closes angle and guarantees to open the unimpeded of runner so that regulate.
Opening on the sidewall can be one, also can symmetry open two, when opening a mouth, three-way valve can be used as the valve of single current passage or water tap uses, promptly advance flatly, about mouthful go out respectively; When opening two mouths, valve or the water tap that can make the threeway double flow channel use, and promptly advance flatly, and two mouthfuls go out simultaneously.During use, change the cooperation position of cock orifice and valve body, thereby reach the purpose of open and close three-way valve by the rotation of handle.
Cock is made with metallic material, preferably adopts copper spare.
Seal ring is made with nonmetallic material, can be working of plastics or rubber parts, and it is shaped as: in be the garden taper, be the garden column outward.This structure can make the inner ring of seal ring cooperate well with cock, and the outer ring cooperates well with valve body.
Between cock and valve gap, adorn a spring, its objective is the interface pressure between automatic regulating cock and the seal ring, thereby guarantee the sealability of three-way valve.When seal ring in use weares and teares, the cock displacement amount is excessive, when causing spring pressure to reduce, can spring be compressed cock downwards by being rotated down valve gap, thereby make cock and seal ring be in the excellent contact state, reaches the effect of sealing.Still can not make the three-way valve sealing if be screwed into limit position under the valve gap, then explanation seal ring this moment may wear to ineffective degree, valve gap can be opened the seal ring that more renews.
In force, according to the difference of using needs, the water outlet of manual threeway can be designed to an end bending of water outlet, Type B structure as a water tap use, it is all crooked also can be designed to two water outlets, C type structure as two water taps use can design 20 kinds by three kinds of structures.
Because manual three-way valve described in the utility model is being done improvement aspect the structure of cock and the entery and delivery port form, thereby reached simple in structure, working service is convenient, and the effect of good seal performance can reach the purpose of a three-way valve as two valves or water tap use simultaneously.
Accompanying drawing 1 is the structural representation of manual three-way valve;
Accompanying drawing 2 is Type B manual three-way valve schematic representation;
Accompanying drawing 3 is C type manual three-way valve schematic representation.
Claims (5)
1, a kind of manual three-way valve that improvement forms on existing valve and water tap basis, by valve body (01), seal ring (02), packing ring (03), handle (04), nut (05), valve rod (06), valve gap (07), spring (08), cock (09) is formed, and cock is a cone, the upper end links to each other with handle by valve rod, handle is fixed with nut, it is characterized in that: cock is positioned at valve body lumen, top seal, the middle part is a cavity, bottom and sidewall opening, the sidewall of cock contacts with seal ring, and valve body lower end is a water intake, a left side, right-hand member is a water outlet, between cock and valve gap spring is housed.
2, manual three-way valve according to claim 1, it is characterized in that: cock is made by metallic material.
3, manual three-way valve according to claim 2 is characterized in that: the opening of cock sidewall is one.
4, manual three-way valve according to claim 2 is characterized in that: the opening of cock sidewall is two of symmetry.
