Abstract
The invention discloses a large-aperture fully-covered eccentric butterfly valve. The large-aperture fully-covered eccentric butterfly valve mainly comprises a valve body, a valve plate, an upper valve rod, a lower valve rod, covering layers and a ceramic layer; the valve plate is arranged in the valve body; the upper part of the valve plate is connected with the upper valve rod and while the lower part of the valve plate is connected with the lower valve rod; the upper valve rod and the lower valve rod are in rotating connection with the valve body; the covering layers cover an inner chamber of the valve body and the valve plate; and the ceramic layer is arranged in the middle part of the valve plate. The large-aperture fully-covered eccentric butterfly valve has a good sealing effect; in addition, the whole valve is uneasy to be corroded; therefore, the applicable scope of the valve is expanded, and the service life of the valve is prolonged, the problem of general excessive torque caused by frequent opening and closing of the valve under a bearing state can be effectively solved, and the sealing effect of the valve is ensured; and the large-aperture fully-covered eccentric butterfly valve has the advantages that the structure is simple, the sealing performance is reliable, the service life is long, the applicable scope is expanded, etc.
Description
Technical field
The present invention relates to valve technology field, more particularly, relate to the complete coated eccentric-butterfly-valve of a kind of heavy caliber.
Background technique
Existing valve is all that metal makes, and after a protracted use, due to souring and corrosive action, causes occurring corrosion or broken hole in valve body, affects the sealability of valve, be difficult to the effect playing opening and closing throttling, affect working life.
Therefore, owing to there is above-mentioned technological deficiency in prior art, be those skilled in that art's technical problems urgently to be resolved hurrily.
Summary of the invention
Object of the present invention, for providing a kind of heavy caliber complete coated eccentric-butterfly-valve, is intended to solve the long-time use existed in prior art and causes corrosion, affect the problem of sealability.
For achieving the above object, the invention provides following technological scheme:
The complete coated eccentric-butterfly-valve of a kind of heavy caliber, mainly comprise valve body, valve plate, upper valve rod, lower valve rod, clad and ceramic layer, valve plate is provided with in described valve body, described valve plate top connects described upper valve rod, described valve plate bottom connects described lower valve rod, described upper valve rod and lower valve rod are rotatably connected with described valve body, are evenly equipped with clad outside described body cavity and valve plate, are provided with ceramic layer in the middle part of described valve plate.
Preferably, described clad is vulcanised rubber layer.
Beneficial effect of the present invention is: sealing effect of the present invention is better, and valve entirety is not easily corroded, and improves the Applicable scope of valve, extends the working life of valve.The sealing effect of the problem that the moment of torsion that the present invention often occurs when frequently opening and closing under effectively solving valve artesian condition is excessive and valve, and in the middle part of valve plate, set up ceramic layer, enhance the shock proof ability of valve plate, therefore the present invention have that structure is simple, sealability is reliable, long service life, the advantage such as applied widely.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
