Description
Technical field
This utility model belongs to universal machine valve technology field, more particularly to a kind of Ceramic Balls of two-piece type structure
Valve.
Background technology
Make rapid progress with scientific and technological, the high speed development of Chemical Engineering Technology, at present, some fluid media (medium)s have high corrosion
Property or there is abrasion simultaneously, this kind of medium is exceedingly fast to the erosive velocity of metal, and conventional metal ball-valve is scrapped soon, only
There is ceramic ball valve just can be competent at.But ceramic ball valve ceramic trim quantity in the market is many, causes the point easily leaking
Also many, the wall thickness of ceramic member is thin, and ceramic material belongs to fragile material simultaneously, actually used in may be because of fluid impurity, improper
The factors such as operation cause ceramic trim to burst apart, and cause medium contacting metal and corrode quickly totally, cause to leak outside, impact produces very
To causing the accident.The reason additionally, due to structure design, the ceramic ball valve on market mostly is undergauge design, and discharge coefficient is little,
Have impact on promoting the use of of ceramic ball valve.
Utility model content
The purpose of this utility model is to improve the deficiency of prior art, provides one kind just to form only with two ceramic members
The independent sealed cavity of ball valve, increases the wall thickness of ceramic member, makes the sealing of ceramic ball valve more reliable, using safer, really
Protect medium and will not touch metal shell, it is possible to achieve rapid-maintenance recovers, the two-piece type ceramic ball valve of long service life.
For realizing this utility model purpose, there is provided technical scheme below: a kind of two-piece type ceramic ball valve, including valve body,
It is characterized in that being arranged with ceramic valve seat in valve body, ceramic valve seat is formed by left valve seat and the docking of right valve seat, and left valve seat includes little
Footpath Duan He great footpath section, big footpath section constitutes ball valve cavity with right valve seat connection end, is provided with ceramic core, Ceramic Balls in ball valve chamber body
Core top is connected with valve rod, and valve rod upper end passes the valve rod hole of left valve seat and valve body, is provided with stuffing-box between valve rod hole and valve rod
With filler pad, on valve rod, set is provided with gland, and valve body right-hand member is provided with right flange, right flange and valve body mode connects for screw,
Right valve seat is crimped with left valve seat.
Preferably, valve body is provided with teflon gasket with the joint face of left valve seat.
Preferably, right flange is provided with teflon gasket with the joint face of left valve seat.
Preferably, the inner surface of left and right valve seat is the curved surface with the cooperation of Ceramic Balls wicking surface, the sealing pair of composition ball valve.
Preferably, being provided with o type ring recess on left valve seat and the vertical connecting end surface of right valve seat, in o type ring recess, it is provided with o
Type circle or teflon gasket.
Preferably, right valve seat right-hand member is plugged in the section of left valve seat big footpath, right-hand member close end is provided with protrusion rim, rim
Surface is connected with left valve seat big footpath section end face.
Preferably, the external connection end of left and right valve seat is all the flange sealing surface of conformance with standard design, there is sealing waterline, directly
Install with field pipes.
Preferably, the wall thickness of left and right valve seat is 22 ~ 30mm.
This utility model beneficial effect: general structure design is short and sweet, it is ceramic left valve seat and ceramic right valve first
Seat defines the ceramic inner chamber of ball valve, and outer leak source is few；The wall thickness of ceramic member has significant increase, and the intensity of pottery has significantly
Raising；The runner of left valve seat, right valve seat and ceramic core is full-bore design, meets using scene to discharge coefficient
Require；The sealing of ceramic inner chamber to be realized by compression, and sealing is safe and reliable；Ceramic left valve seat and ceramic right valve seat outer
Portion is to be all the flange sealing surface that conformance with standard designs, and has sealing waterline, can directly install with field pipes.On valve body and a left side
Between valve seat, between right valve seat and right flange, it is designed with teflon gasket, adjustment when assembling for valve.This reality
With the new technical requirements that disclosure satisfy that using scene, realize Fast Installation and Fast-Maintenance, the service life of valve is able to greatly
Width improves, and can greatly improve the economical production scale of enterprise, obtains economic benefit.
