Abstract
The utility model discloses a kind of metal valve plug, comprise metal valve plug body, described metal valve plug body is provided with adjustable lever, metal valve plug body comprises valve plug upper end, valve plug middle-end and valve plug lower end, the surface of described valve plug upper end adopts the first cone structure, the surface of valve plug lower end adopts the second cone structure, and valve plug upper end adopts valve plug middle-end to be connected with valve plug lower end formation integrative-structure.The utility model realizes hard sealing by adopting metal valve plug body, the surface of valve plug upper end adopts the first cone structure simultaneously, valve plug lower end adopts the second cone structure, not only have higher sealability, can reduce fluid by being the resistance produced, circular groove structure reduces the fabricating cost of metal valve plug body simultaneously, symplex structure centered by metal valve plug body, make it have higher concentricity, prevent from rocking generation gap, improve sealability.
Description
[technical field]
The utility model relates to the technical field of valve plug, particularly the technical field of the metal valve plug of central air-conditioner modulating valve.
[background technique]
Along with the raising that people require comfort of air conditioner, and the problem such as air conditioner energy saving becomes the focus of concern day by day, and auto-adjustment control obtains within air-conditioning systems and applies more and more widely.Electric control valve for air-conditioner water system automatically regulates one of basic final controlling element.Electric control valve is located on air-conditioning box return pipe usually, is changed the output load of air-conditioning box by regulating water flow, to adapt to the change of room actual load, keeps indoor air temperature in air conditioned building constant.Characteristic at present about modulating valve has more research, but the inner plastic valve that mostly adopts of traditional modulating valve fills in row soft seal, sealability is general, modulating valve cannot be made to regulate the actual load of air-conditioning box accurately, be difficult to keep indoor air temperature in air conditioned building constant, and traditional valve plug concentricity is lower, easily rocks and produce gap, cause sealability to reduce.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of metal valve plug, has higher concentricity, prevents from rocking producing gap, adopts metal valve to fill in the hard sealing of row simultaneously, improves overall sealability.
For achieving the above object, the utility model proposes a kind of metal valve plug, comprise metal valve plug body, described metal valve plug body is provided with adjustable lever, metal valve plug body comprises valve plug upper end, valve plug middle-end and valve plug lower end, the surface of described valve plug upper end adopts the first cone structure, and the surface of valve plug lower end adopts the second cone structure, and valve plug upper end adopts valve plug middle-end to be connected with valve plug lower end formation integrative-structure.
As preferably, described adjustable lever is connected with valve plug upper end.
As preferably, formed by described first cone structure and vertical plane, acute angle is 20 ~ 50 °, and formed by the second cone structure and vertical plane, acute angle is 20 ~ 50 °.
As preferably, described valve plug middle-end adopts column construction, is provided with circular groove structure between valve plug upper end and valve plug lower end.
As preferably, symplex structure centered by described metal valve plug body.
The beneficial effects of the utility model: the utility model realizes hard sealing by adopting metal valve plug body, the surface of valve plug upper end adopts the first cone structure simultaneously, valve plug lower end adopts the second cone structure, not only there is higher sealability, fluid can be reduced by being the resistance produced simultaneously, circular groove structure reduces the fabricating cost of metal valve plug body, symplex structure centered by metal valve plug body, make it have higher concentricity, prevent from rocking and produce gap, improve sealability.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the plan view of a kind of metal valve plug of the utility model.
In figure: 1-metal valve plug body, 2-adjustable lever, 3-valve plug upper end, 4-valve plug middle-end, 5-valve plug lower end, 31-first cone structure, 41-circular groove structure, 51-second cone structure.
[embodiment]
Consult Fig. 1, a kind of metal valve plug of the utility model, comprise metal valve plug body 1, described metal valve plug body is provided with adjustable lever 2, metal valve plug body comprises valve plug upper end 3, valve plug middle-end 4 and valve plug lower end 5, the surface of described valve plug upper end 3 adopts the first cone structure 31, the surface of valve plug lower end 5 adopts the second cone structure 51, valve plug upper end 3 adopts valve plug middle-end 4 to be connected with valve plug lower end 5 formation integrative-structure, described adjustable lever 2 is connected with valve plug upper end 3, described first cone structure 31 is 20 ~ 50 ° with acute angle formed by vertical plane, second cone structure 51 is 20 ~ 50 ° with acute angle formed by vertical plane, described valve plug middle-end 4 adopts column construction, circular groove structure 41 is provided with between valve plug upper end 3 and valve plug lower end 5, symplex structure centered by described metal valve plug body 1.
Utility model works process:
A kind of metal valve plug of the utility model in the course of the work, hard sealing is realized by adopting metal valve plug body 1, the surface of valve plug upper end 3 adopts the first cone structure 31 simultaneously, valve plug lower end 5 adopts the second cone structure 51, not only there is higher sealability, fluid can be reduced by being the resistance produced simultaneously, circular groove structure 41 reduces the fabricating cost of metal valve plug body 1, symplex structure centered by metal valve plug body 1, make it have higher concentricity, prevent from rocking and produce gap, improve sealability.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
