Abstract
The utility model discloses a ceramic hard seal double-eccentric flexible dome valve. A ceramic hard sealing ring (3) for a valve body (1) is arranged on the valve body (1), a ceramic hard sealing ring (4) for a valve plate (2) is arranged on the valve plate (2), the ceramic hard sealing ring (3) for the valve body (1) is inlayed on a valve seat (5), the valve seat (5) is fixed on the valve body (1) by a bolt, the ceramic hard sealing ring (4) for the valve plate (2) is fixed on the valve plate (2) by a pressure plate, a rubber sealing ring (7) for a telescopic pipe (6) is arranged on the telescopic pipe (6), and the rubber sealing ring (7) for the telescopic pipe (6) is fixed on the telescopic pipe (6) by a pressure plate.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of ceramic hard sealing double eccentric dome valve that stretches.
Background technique
The present two eccentric circle overhead-valve doors that use, the sealing pair that adopts stainless steel or alloy to make, in use, owing to the burn into of medium such as washes away at reason, damage easily at short notice and cause leakage, conventional valve causes valve can't install or the method hurdle is broken in use because piping erection error and variation of temperature can cause the pipeline axial displacement, brings certain influence for the normal operation of production.
Summary of the invention
The purpose of this utility model be to overcome above-mentioned deficiency of the prior art exactly and a kind of corrosion resistance be provided, prevent to reveal, the flexible dome valve of non-damageable ceramic hard sealing double eccentric.
For achieving the above object, the utility model is to adopt following scheme to be achieved in that a kind of ceramic hard sealing double eccentric extension valve, it is made up of valve body (1), valve plate (2), telescopic pipe (6), it is characterized in that: valve body (1) is provided with the hard seal ring (3) of valve body pottery, valve plate (2) is provided with the hard seal ring (4) of valve plate pottery, the hard seal ring (3) of valve body pottery is embedded on the valve seat (5), valve seat (5) is by being bolted on the valve body (1), and the hard seal ring (4) of valve plate pottery is fixed on the valve plate by platen; Telescopic pipe (6) is provided with telescopic rubber seal ring (7), and telescopic rubber seal ring (7) is fixed on the telescopic pipe (6) by platen.
The utility model advantage:
1, be that occurring in nature hardness is only second to adamantine characteristics according to pottery, with valve contact medium position and front cover adopting process ceramic treatment, make the hard sealed valve of pottery, can guarantee long-time stable work under harsh industrial and mineral condition, solve in the past the short not anti abrasive drawback of life of valve, thereby reached wear-resisting, corrosion protection, good antiscale property, high temperature resistant, effect that the life-span is long.
2, valve plate, the hard seal ring of valve body pottery, telescopic rubber seal ring are fixed by platen, can change at any time under damage situations.
3, this valve can compensate automatically because the piping displacement that temperature variation causes can be adjusted structure length according to the mounting point in installation process.
4, adjustable platen structure is adopted in flexible sealing, in use can obtain rational seal pressure by adjusting the platen bolt, guarantees to work long hours not have and reveals.
5, this valve adopts two eccentric structures, and valve plate is the semi major axis dome structure, can effectively reduce the wearing and tearing of the hard seal ring of pottery in opening-closing process, and after the unlatching, the dome valve plate enters valve pocket, avoids medium because of washing away valve plate, causes the wearing and tearing of ceramic seal circle.
