Abstract

The utility model discloses a kind of core of ball valve, including body, passage or cavity are communicated with the body, body is located to be offered for interface channel or cavity and the opening of extraneous conducting respectively at the axial both ends of communicating passage or cavity, one of opening of the body is circular port, the adjustment hole of " V " type is connected with rounded opening edge, adjustment hole is connected one end with circular port as big end, and the other end is small end；" V " type direction of adjustment hole overlaps with the middle stringcourse of body.The beneficial effects of the utility model are：One side opening of core body is the adjustment hole that V-type is opened up on circular port, and one side circular port contributes to medium full by V-type adjustment hole then can more be accurately controlled flow and calculate flow；Other another side opening is that hemispherical opening or section are inclined to set with the end section of circular port one, helps to reduce regulation moment of torsion, is easy to use actuator to carry out quick regulation, contributes to the use of smart machine.

Description

A kind of core of ball valve

Technical field

It the utility model is related to a kind of ball valve of accurate flow control, more particularly to a kind of core of ball valve.

Background technology

Ball valve is a kind of very extensive valve of purposes, is mainly used in, to carrying out on/off control by the medium of valve, opening The stroke of valve is mostly to be rotated by 90 °, and its aperture-flow curve is fast open form curve, is difficult to the medium flow field to flowing through valve body Amount carries out accurate adjustment, but the maximum feature of ball valve is that cost is low, is easily worked and the moment of torsion of controlled valve is small and balanced, Digitlization close/open valve gate control is easily achieved, therefore, the scope of application of ball valve is very wide at present.The main body of ball valve is a flow Passage, the size of flow and keying are mainly controlled by core rotation in it, therefore the structure of core directly affects flow control The precise degrees of system, it is to control flow with V-type core mostly at present, current V-type core structure is one of core body Export and be correspondingly arranged a V-type outlet for arc opening, the arc string of arc opening, the V-type core of this structure first can not Full by having an impact to flow, secondly because V-type adjustment hole aperture is too big corresponding to arc string, regulation is not accurate enough.

Utility model content

For the problems of the prior art, the purpose of this utility model is to provide for a kind of core of ball valve.

In order to achieve the above object, the technical solution of the utility model is：A kind of core of ball valve, including body, it is described Passage or cavity are communicated with body, body is located at the axial both ends of communicating passage or cavity to offer respectively and led to for connection Road or cavity and the opening of extraneous conducting, one of opening of the body is circular port, is connected with " V " on rounded opening edge The adjustment hole of type, adjustment hole are connected one end with circular port as big end, and the other end is small end；" V " type direction and body of adjustment hole Middle stringcourse overlap.

Preferably, the improvement as above-mentioned technical proposal, opposite side opening section and the circular port opening of the body are cut Face is angle of inclination.

Preferably, the improvement as above-mentioned technical proposal, another side opening of the body is hemispherical opening.

The beneficial effects of the utility model are：One side opening of core body is that the adjustment hole of V-type is opened up on circular port, one Aspect circular port contributes to medium full by V-type adjustment hole then can more be accurately controlled flow and calculate flow；It is another in addition One side opening is that hemispherical opening or section are inclined to set with the end section of circular port one, helps to reduce regulation moment of torsion, is easy to Quick regulation is carried out using actuator, contributes to the use of smart machine.

Fig. 4 is the structural representation of another side opening of the present utility model.

Embodiment

The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing, it is clear that described Embodiment is the utility model part of the embodiment, rather than whole embodiments.Based on the embodiment in the utility model, sheet The every other embodiment that field those of ordinary skill is obtained under the premise of creative work is not made, belongs to this practicality Novel protected scope.

, it is necessary to explanation in description of the present utility model, term " " center ", " on ", " under ", it is "left", "right", " perpendicular Directly ", the orientation of the instruction such as " level ", " interior ", " outer " or position relationship are based on orientation shown in the drawings or position relationship, are only Described for the ease of description the utility model and simplifying, rather than instruction or imply signified device or element must have it is specific Orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.In addition, term " the One ", " second ", " the 3rd " are only used for describing purpose, and it is not intended that instruction or hint relative importance.

, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in description of the present utility model Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly Connection；Can be mechanical connection or electrical connection；Can be joined directly together, can also be indirectly connected by intermediary, It can be the connection of two element internals.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition Concrete meaning of the language in the utility model.

As shown in Fig. 1 Fig. 2 Fig. 3 Fig. 4, a kind of core of ball valve, including body 1, passage is communicated with the body 1 Or cavity 2, body 1 is located at the axial both ends of communicating passage or cavity 2 to be offered for interface channel or cavity and the external world respectively The opening of conducting, one of opening of the body is circular port 3, and the adjustment hole 4 of " V " type is connected with the edge of circular port 3, Adjustment hole 4 is connected one end with circular port 3 as big end, and the other end is small end；" V " type direction and the middle stringcourse of body 1 of adjustment hole 4 Overlap.Another side opening 5 of the body 1 is hemispherical opening, and opposite side opening section and the opening of circular port 3 of body 1 are cut Face is angle of inclination.

When actual use, a side opening of core body 1 is opens up the adjustment hole 4 of V-type, a side on circular port 3 Face circular port 3 contributes to medium full by V-type adjustment hole 4 then can more be accurately controlled flow and calculate flow；It is another in addition One side opening 5 is that hemispherical opening or section are inclined to set with the end section of circular port 3 one, helps to reduce regulation moment of torsion, just In carrying out quick regulation using actuator, contribute to the use of smart machine.

It is new that all simple deformations made in the case where not departing from the utility model core or modification each fall within this practicality The protection domain of type.
