Abstract

The utility model discloses a valve core of a hemispherical valve. The valve core comprises a hemispherical shell, wherein an upper half shaft mounting base is arranged at the upper end of the shell; a lower half shaft mounting base is arranged at the lower end of the shell; reinforcing ribs are connected between the upper half shaft mounting base and the inner wall of the shell, and between the lower half shaft mounting base and the inner wall of the shell; and a hemi-circular groove is formed in the outer side wall of the shell. The valve core is simple in structure, convenient to mount and use, and high in working efficiency, meanwhile the service life is prolonged, and the economic benefit is improved. Therefore, the valve with the valve core is wider in application range.

Description

A kind of spool of semispherical valve
Technical field
The utility model relates generally to pipe control valve field, relates in particular to a kind of spool of semispherical valve.
Background technique
It is a lot of to work the ball valve kind of blocking medium in pipeline, the spool that hard sealed eccentric ball valve and soft seal semispherical valve are arranged, the sealing of the spool of hard seal semi ball valve is metal to metal, phase-contact surface meeting phase mutual friction after long-time the use, make and be sealed with certain leakage, the sealing of the spool of soft seal semispherical valve is metal pair rubber, phase-contact surface can the phase mutual friction after long-time the use, sealing can reach zero leakage, although existing soft sealing structure reaches the effect of zero sealing in use in the market, but its complex structure, installation and maintenance are inconvenient, particularly slightly use in the environment in the evil that fouling occurs easily, because the generation of scale formation has influence on the freely unlatching of valve, reduced working efficiency, affected working life and economic benefit.
The model utility content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of spool of semispherical valve to be provided, and has solved the problem of complex structure, installation and maintenance inconvenience, and convenient and fast connection with the pipeline of various diameters, the opening and closing of spool are accurately convenient.
The utility model is achieved through the following technical solutions:
A kind of spool of semispherical valve, include hemispheric housing, the housing upper end is for being provided with upper semiaxis fitting seat, the lower end of housing is provided with lower semiaxis fitting seat, be connected with stiffening rib between the inwall of described upper semiaxis fitting seat, lower semiaxis fitting seat and housing, described hull outside wall is provided with semicircular groove.
The quantity of described stiffening rib has five, and annular is evenly arranged.
Working principle of the present utility model is to make valve unimpeded or inaccessible by rotary spool, simultaneously between upper and lower semiaxis and the bearing support and adopt respectively soft sealing structure between hemisphere spool and valve flowing channel one side, so that ball valve switch is light, sealing is reliable, sealing surface and the sphere closed state of being everlasting is difficult for by the medium erosion; And the connection between its each parts is simple, sealing, firm, can be because not using for a long time the freely unlatching of breaking down or having influence on valve because of the generation of scale formation.
Advantage of the present utility model is as follows:
The utility model is simple in structure, easy to install, high working efficiency, has improved simultaneously working life and economic benefit, so that the more extensive spool of the application area of this type of valve, opening and closing are accurately convenient.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
3, referring to accompanying drawing, a kind of spool of semispherical valve, include hemispheric housing 1, housing 1 upper end is for being provided with upper semiaxis fitting seat 2, the lower end of housing is provided with lower semiaxis fitting seat 3, is connected with stiffening rib 4 between the inwall of upper semiaxis fitting seat, lower semiaxis fitting seat and housing 1, and the quantity of stiffening rib 4 has five, and annular is evenly arranged, and housing 1 outer side wall is provided with semicircular groove 5.
