Abstract
The utility model discloses a connecting and buckling device for an eccentric semispherical valve. A flow inlet and a flow outlet are respectively formed in the two sides of a spherical valve body; an upper half shaft is arranged on the top of the valve body in a rotatable manner; a lower half shaft is arranged at the bottom of the valve body in a rotatable manner; and semicircular buckles are respectively hinged at the two ends of the valve body and are provided with grooves matched with a pipeline flange plate. The connecting and buckling device is simple in structure and high in working efficiency and convenient to mount and use; moreover, the service life is prolonged, and the economical benefit is improved; and the valve of the type can be widely applied.
Description
Technical field
The utility model relates generally to pipe control valve field, relates in particular to a kind of eccentric half-ball valve Connection Card fastener device.
Background technique
It is a lot of to work the ball valve kind of blocking medium in pipeline, hard sealed eccentric ball valve and soft seal eccentric half-ball valve Connection Card fastener device are arranged, hard seal eccentric semi ball valve is metal to metal with the sealing of Connection Card fastener device, phase-contact surface meeting phase mutual friction after long-time the use, make and be sealed with certain leakage, the soft seal eccentric half-ball valve is metal pair rubber with the sealing of Connection Card fastener device, 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 eccentric half-ball valve Connection Card fastener device to be provided, and has solved complex structure, installation and maintenance are inconvenient, and convenient and fast connection with the pipeline of various diameters, join strength is good.
The utility model is achieved through the following technical solutions:
A kind of eccentric half-ball valve Connection Card fastener device, both sides at the valve body of sphere are respectively equipped with the influent stream mouth, go out head piece, described valve body top is rotatablely equipped with semiaxis, described valve body is rotatablely equipped with lower semiaxis in the bottom, the two ends of described valve body are hinged with respectively semicircular buckle, and described buckle has the groove that matches with pipeline flanges.
Described semicircular buckle material is aluminum alloy.
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 application area of this type of valve is more extensive.
Description of drawings
Fig. 1 is the utility model structural representation.
