Abstract
The utility model discloses a valve core for an eccentric half ball valve. The valve core comprises a hemispherical body, wherein a cavity is formed in the hemispherical body; a vertical mounting hole is formed in the end surface of the hemispherical body; internal screw threads are respectively formed at the two ends of the mounting hole; a connecting plate is arranged in the cavity; and the two ends of the connecting plates are respectively connected with the hemispherical body and the mounting hole. 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
Technical field
The utility model relates generally to pipe control valve field, relates in particular to a kind of eccentric half-ball valve spool.
Background technique
In pipeline, work the ball valve kind of blocking medium a lot, hard sealed eccentric ball valve and soft seal eccentric half-ball valve are arranged, the sealing of hard seal eccentric 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 soft seal eccentric half-ball 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 easily occurs, have influence on the freely unlatching of valve because of the generation of scale formation, 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 spool to be provided, and solved the problem of complex structure, installation and maintenance inconvenience, and the current water outlet is stablized smooth and easy more, guaranteed that long-term use needn't change.
The utility model is achieved through the following technical solutions:
A kind of eccentric half-ball valve spool, include hemisphere, has cavity in the described hemisphere, be provided with vertical installation duct in the described hemispheroidal end face, the two ends that the duct is installed are respectively equipped with internal thread, be provided with connecting plate in the described cavity, the connecting plate two ends are connecting respectively hemisphere, the duct are being installed.
Have the mistake water flow passage of rectangle on the described spool outer side wall.
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, the current water outlet is stablized smooth and easy more, has guaranteed that long-term use needn't change.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of eccentric half-ball valve spool, include hemisphere 1, has cavity 2 in the hemisphere 1, be provided with vertical installation duct 3 in the end face of hemisphere 1, the two ends that duct 3 is installed are respectively equipped with internal thread 4, are provided with connecting plate 5 in the cavity, connecting plate 5 two ends are connecting respectively hemisphere, the duct are being installed, and have the mistake water flow passage 6 of rectangle on the spool outer side wall.
Claims (2)
1. eccentric half-ball valve spool, include hemisphere, it is characterized in that: have cavity in the described hemisphere, be provided with vertical installation duct in the described hemispheroidal end face, the two ends that the duct is installed are respectively equipped with internal thread, be provided with connecting plate in the described cavity, the connecting plate two ends are connecting respectively hemisphere, the duct are being installed.
2. eccentric half-ball valve spool according to claim 1 is characterized in that: the mistake water flow passage that has rectangle on the described spool outer side wall.
