Abstract
The utility model discloses a kind of two lining ball valve, ceramic-lined, valve rod, filler, pressure ring and the seal ring composition that the ectosome of flange and the valve body formation be made of metal, flange liner and valve body liner are formed, be characterized in ectosome and ceramic-lined between be provided with PTFE liner, the utility model have 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, the feature of long service life.
Description
Technical field
The utility model belongs to universal machine valve technology field, particularly relates 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 purpose of this utility model be 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 purpose of this utility model realizes 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 the purpose of this utility model further, can be described PTFE liner be integral type.
In order to realize the purpose of this utility model 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 the purpose of this utility model 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 the purpose of this utility model 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 utility model has following distinguishing feature and good effect: the utility model is extremely strong or that abrasion is very strong simultaneously occasion for 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.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is another kind of structural representation of the present utility model.
Embodiment
Embodiment 1, a kind of two lining ball valve, with reference to Fig. 1, that ball core 1 is installed in valve body, the lower end of valve rod 13 connects ball core 1, metal flange 12 is fixed with respectively by bolt at the two ends, left and right of valve body 6, valve body 6 and metal flange 12 form metal shell, ceramic flange liner 11 is provided with in metal flange 12, valve seat 4 is arranged on valve body 6, inside metal flange 12 and ceramic flange liner 11, valve body liner 2 is installed between valve seat 4 and valve body 6, it is ceramic-lined that flange liner 11 and valve body liner 2 are formed, filler 14 is provided with between valve body 6 and valve rod 13, packing press ring 10 to be installed above filler 14 and is compressed filler 14, metal shell and ceramic-lined between be provided with PTFE liner 5, described PTFE liner 5 is integral types, this forms a kind of structure of the present utility model.
Embodiment 2, a kind of two lining ball valve, with reference to Fig. 2, on the basis of embodiment 1, described PTFE liner between flange liner 11 and flange 12, is provided with flange two serve as a contrast 8, be provided with valve body two between valve body liner 2 and valve body 6 and serve as a contrast 3, distance ring 9 elastic conjunction serves as a contrast 8 at flange two, flange liner 11, valve seat 4, valve body liner 2, valve body two serves as a contrast between 3, the outer side elevation of distance ring 9 and flange liner 2, flange two serves as a contrast the facade contact of 3, the inside, inner side and valve body liner 2, valve body two serves as a contrast 3, the facade contact of valve seat 4, upper surface, lower surface serves as a contrast 8 with flange two respectively, valve seat 4 contacts, the facade of distance ring 9 and the facade contacting point of valve seat 4 are provided with leaf spring 7, other are identical with embodiment 1.
O type circle can be used between parts of the present utility model as required to seal the Seal cage being formed and close.
