Abstract
The invention discloses a double lining ball valve which is composed of an outer body, a ceramic lining, a valve rod, a filler, a pressing ring and a sealing ring, wherein the outer body is formed by a flange made of metal and a valve body, and the ceramic lining is formed by a flange lining and a valve body lining. The double lining ball valve is characterized in that a polytetrafluoroethylene (PTFE) lining is arranged between the outer body and the ceramic lining. The double lining ball valve disclosed by the invention has the characteristics that double linings are used, the PTFE lining and the ceramic lining are lined in the outer body, two independent sealing cavities are formed, a split medium in the ceramic lining is not in contact with the metal; outleakage does not occur through the valve, fast maintenance and recovering can be realized, and the service life is long.
Description
Technical field
The invention belongs to universal machine valve technology field, particularly relate to a kind of ball valve with two lining structure.
Background technique
Along with making rapid progress of science and technology, the high speed development of Chemical Engineering Technology, at present, some flowing medium has high corrosivity or has abrasion simultaneously, the erosive velocity of this kind of medium to metal is exceedingly fast, and common metal ball valve gives up soon, only has ceramic ball valve to be competent at.But pottery belongs to brittle material, may cause ceramic-lined bursting apart because of the factor such as fluid impurity, abnormal operation in actual use, cause medium contact metal and corrode very soon totally, causing and leak outside, impact is produced and even can be caused the accident.
Summary of the invention
The object of the invention is to improve the deficiency of prior art and provide a kind of and adopt two liner, ectosome inner liner polytetrafluoroethylene liner and ceramic-lined, to form twice autonomous closure Seal cage, the ceramic-lined medium that bursts apart can not touch metal, valve can not leak outside, can realize that rapid-maintenance recovers, two lining ball valves of long service life.
The object of the present invention is achieved like this, a kind of two lining ball valve, ceramic-lined, valve rod, filler, pressure ring and the seal ring composition that ectosome, flange liner and valve body liner that the flange that is made of metal and valve body are formed are formed, be characterized in ectosome and ceramic-lined between be provided with PTFE liner.
In order to realize object of the present invention further, can be described PTFE liner be integral type.
In order to realize object of the present invention further, can be described PTFE liner be between flange liner and flange, be provided with flange two lining, be provided with valve body two lining between valve body liner and valve body, distance ring elastic conjunction serve as a contrast at flange two, flange liner, valve seat, valve body liner, valve body two lining between.
In order to realize object of the present invention further, can be that the outer side elevation of described distance ring contacts with the facade that flange liner, flange two serve as a contrast, the inside, inner side serves as a contrast with valve body liner, valve body two, the facade of valve seat contacts, and upper surface, lower surface serve as a contrast with flange two respectively, valve seat contacts.
In order to realize object of the present invention further, can be that the facade of described distance ring and the facade contacting point of valve seat are provided with leaf spring.
Compared with the prior art the present invention has following distinguishing feature and good effect: the present invention is directed to extremely strong or that abrasion is the very strong simultaneously occasion of corrosive medium, fundamentally improve existing ball-valve structure, thus to create with metal be ectosome, inner liner polytetrafluoroethylene (being called for short PTFE), again at PTFE lined ceramics, PTFE liner forms the Seal cage of one autonomous closure; The Seal cage of another road autonomous closure of ceramic-lined formation, form the ball valve with two lining structure, even if this structure can ensure to run into special circumstances, cause ceramic-lined bursting apart, medium also can not touch metal, guarantee valve can not leak outside by PTFE liner, have crackle although now ceramic-lined, but still the strong abrasion of flowing medium can be born, and the severe corrosive of medium there is PTFE to bear, valve still can ensure not affect use, than conventional ceramic valve indirectly improve life-span manyfold; The facade of distance ring and the facade contacting point of valve seat are provided with leaf spring, distance ring and PTFE liner is made to compress to be formed and seal, because decrement reserved by the distance ring of PTFE material, therefore press seal is effective, and valve can be reduced when being squeezed in pipeline, ceramic flange liner is delivered to leaf spring, then passes to the thrust on the valve seat of ceramic material, reduces the generation of valve torque rising problem.
