Abstract
The invention discloses a two-piece type ceramic ball valve which comprises a valve body, wherein a ceramic valve seat is arranged in the valve body in a sleeving manner and is formed by butting a left valve seat and a right valve seat; the left valve seat comprises a small-diameter section and a large-diameter section; the large-diameter section and the connection end of the right valve seat form a ball valve cavity; a ceramic ball core is arranged in the ball valve cavity; the top end of the ceramic ball core is connected with a valve rod; the upper end of the valve rod penetrates through a valve rod hole in the left valve seat and the valve body; a stuffing box and a stuffing gasket are arranged between the valve rod hole and the valve rod; a stuffing gland is arranged on the valve rod is a sleeving manner; a right flange is arranged at the right end of the valve rod and is connected with the valve body through a bolt, to connect the right valve seat to the left valve seat in a pressing manner. The two-piece type ceramic ball valve is reliably sealed, can resist high temperature and has higher wear and corrosion resistance performance.
Description
Technical field
The invention belongs to universal machine valve technology field, particularly relate to the ceramic ball valve of a kind of two-piece type structure.
Background technology
Along with scientific and technological is maked rapid progress, the high speed development of Chemical Engineering Technology, at present, some fluid media (medium) has high corrosivity or has abrasion simultaneously, the erosive velocity of metal is exceedingly fast by this kind of medium, and conventional metal ball-valve is scrapped soon, and only ceramic ball valve just can be competent at.But ceramic ball valve ceramic trim quantity in the market is many, the point causing easily leakage is the most, the wall thickness of ceramic member is thin, ceramic material belongs to fragile material simultaneously, ceramic trim may be caused to burst apart because of the factor such as fluid impurity, abnormal operation in actually used, causing medium contacting metal and quickly corrode totally, causing and leak outside, impact produces and even causes the accident.Additionally, due to the reason of structure design, the ceramic ball valve on market mostly is undergauge design, and discharge coefficient is little, also have impact on promoting the use of of ceramic ball valve.
Summary of the invention
It is an object of the invention to improve the deficiency of prior art, a kind of independent sealed cavity just constituting ball valve only with two ceramic members is provided, increase the wall thickness of ceramic member, the sealing making ceramic ball valve is more reliable, use safer, guarantee that medium will not touch metal shell, it is possible to achieve rapid-maintenance recover, service life length two-piece type ceramic ball valve.
For realizing the object of the invention, provide techniques below scheme: a kind of two-piece type ceramic ball valve, including valve body, it is arranged with ceramic valve seat in it is characterized in that valve body, ceramic valve seat is docked by left valve seat and right valve seat and forms, left valve seat includes path section and big footpath section, big footpath section is connected end and constitutes ball valve cavity with right valve seat, pottery core it is provided with in ball valve chamber body, pottery core top connects valve rod, valve rod upper end passes the valve rod hole of left valve seat and valve body, stuffing-box and filler pad it is provided with between valve rod hole and valve rod, on valve rod, set is provided with gland, valve body right-hand member is provided with right flange, right flange is connected with valve body screw, right valve seat is crimped with left valve seat.
As preferably, valve body is provided with teflon gasket with the joint face of left valve seat.
As preferably, right flange is provided with teflon gasket with the joint face of left valve seat.
As preferably, the inner surface of left and right valve seat is the curved surface coordinated with Ceramic Balls wicking surface, the sealing pair of composition ball valve.
As preferably, left valve seat is provided with O groove on the vertical connecting end surface of right valve seat, is provided with O or teflon gasket in O groove.
As preferably, right valve seat right-hand member is plugged in the section of left valve seat big footpath, and right-hand member close end is provided with protrusion rim, and rim surface footpath big with left valve seat section end face connects.
As preferably, the external connection end of left and right valve seat is all the flange sealing surface of conformance with standard design, has sealing waterline, directly installs with field pipes.
As preferably, the wall thickness of left and right valve seat is 22 ~ 30mm.
The method have the benefit that general structure design is short and sweet, first it is the ceramic inner chamber that ceramic left valve seat and the right valve seat of pottery define ball valve, and outer leak source is few；The wall thickness of ceramic member has had a significant increase, and the intensity of pottery has had and is greatly improved；The runner of left valve seat, right valve seat and pottery core is full-bore design, meets and uses the on-the-spot requirement to discharge coefficient；The sealing of pottery inner chamber is realized by compression, and sealingly secure is reliable；The left valve seat of pottery and the outside of the right valve seat of pottery are to be all the flange sealing surface of conformance with standard design, have sealing waterline, can directly with field pipes installation.Between valve body and left valve seat, between right valve seat and right flange, it is designed with teflon gasket, the adjustment for valve assembles time.The present invention disclosure satisfy that and uses on-the-spot technology requirement, it is achieved Fast Installation and Fast-Maintenance, is greatly improved the service life of valve, it is possible to be greatly improved the economical production scale of enterprise, it is thus achieved that economic benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
