Abstract
The utility model discloses an abrasive and corrosive resistant gate valve with ceramic lining. The valve body adopts metal element. The entire inner wall of the valve body adds to provide alumina, zircite and zirconia toughened alumina ceramic element. The draw rod adds to provide protection outer coat, while throttling point is equipped with a seal ring and a damper. The draw rod outer coat, the seal ring and the damper all adopt alumina, zircite and zirconia toughened alumina ceramic element. The structure can ensure that what the valve and the mediums like the liquid, the powder, the gas and so on contact are all special ceramics when the valve throttles and closes, making the metal surface and the conveyance medium separate perfectly; as a consequence it prolongs the service life of the valve; it applies in the industries like petroleum, metallurgy, chemical engineering, mine, etc.
Description
One, technical field
The utility model relates to a kind of valve type mechanical device of control media transportation in the industries such as oil, rock gas, chemical industry, thermal power plant, metallurgy, mine, particularly relates to a kind of wear resistant corrosion resistant and serves as a contrast pottery wear resistant corrosion resistant gate valve entirely.
Two, background technique
Gate valve is a kind of means of transportation of a large amount of control powders that use, liquid, gas flow in the industries such as oil, chemical industry, metallurgy, mine, thermoelectricity plant, easily worn parts such as the valve seat of valve, flap, valve rod adopt the method for stainless steel, cast iron, chromium plating, carburizing or carbonitriding, nitriding treatment more both at home and abroad, are difficult to normal the use under the industrial and mineral mal-condition; Domestic in addition have employing at present at vice division chief's edge corrosion-resistant, wear-resistant stone casting of one deck or the ceramic fitting of rubbing, but all only only limit to the friction pair place, rather than full lining pottery, and other position still can not guarantee the long lifetime use.
Three, summary of the invention
The purpose of this utility model is to provide a kind of full lining pottery wear resistant corrosion resistant gate valve of being made by big, wear-resistant, corrosion-resistant, the anti-special ceramic material that washes away of hardness, and, gate valve structure has been made the existing deficiency that corresponding change has overcome prior art according to the performance that stupalith itself has.
The purpose of this utility model is achieved in that a kind of full lining pottery wear resistant corrosion resistant gate valve, it is characterized in that: valve body (15) adopts metalwork, the whole valve body inwall is set up protective layer (4), (7), (9), (13), and pull bar (6) is set up protection overcoat (5), the throttling place is provided with seal ring (1) and flashboard (12); Joint, two ends between wear resistant corrosion resistant pottery (1) and the valve body (15) is provided with corrosion-resistant seal ring (2); Go up the processing guiding groove at wear resistant corrosion resistant pottery (4), guiding groove is cooperated suitably with ceramic SDeflector (8); Edge one deck polyurethane (11) between wear resistant corrosion resistant pottery (12) and the pull bar (6), pull bar (6) two ends are respectively equipped with block (10) and wear resistant corrosion resistant Bond (3); Valve body (15) side is provided with slag guiding trough (14), adopts bolt to be connected between valve body (15) and the base (16); Valve body (15) is provided with positioning device (17) with the joint of wear resistant corrosion resistant pottery (1); Valve body (15) takes symmetry to cut structure open at the runner place, is threaded then; Protective layer (4), (7), (9), (13), the protection overcoat (5) of pull bar (6), the material of seal ring (1) and flashboard (12) all adopts aluminium oxide, zirconium oxide and Zirconia reinforced alumina ceramic spare.
Full lining pottery wear resistant corrosion resistant gate valve of the present utility model; its valve body adopts metalwork; the whole valve body inwall is set up aluminium oxide, zirconium oxide and Zirconia reinforced alumina ceramic spare; pull bar is set up the protection overcoat, the throttling place is provided with seal ring and flashboard, and rod outer sleeve, seal ring and flashboard all adopt aluminium oxide, zirconium oxide and Zirconia reinforced alumina ceramic spare.What this structure can guarantee that valve contacts with media such as liquid, powder, gases when closing in throttling all is special cermacis, metal covering and fed sheet of a media are separated fully, thereby prolong the working life of valve greatly, be applied in widely in the industries such as oil, metallurgy, chemical industry, mine, significantly reduce enterprise's cost of production.
