Abstract
A ceramic hard seal stop valve is used in fields such as petroleum industry, chemical engineering industry, chemical fiber industry, petroleum refining industry, metallurgy industry, thermal power plants, nuclear power stations, and the like, and used in a system of high-temperature high-pressure pipelines. In a valve body, a ceramic valve seat and a metal valve body are matched in a hot charging manner; a ceramic sealing piece and a metal valve clack are matched in a hot-embedded impaction manner; and a hand wheel or other electric and pneumatic actuating manners can be adopted outside the metal valve body. An actuator drives the metal valve clack and the ceramic sealing piece to do work through a metal valve rod; the ceramic sealing piece is matched with the ceramic valve seat in a hard seal manner, so as to guarantee the favorable sealing effect; and as the ceramic sealing piece and the ceramic valve seat adopt superhard wear-resistant industrial ceramics, the erosion and abrasion loss caused by the material are greatly lessened, and the service life of the ceramic stop valve is prolonged.
Description
Affiliated technical field:
The utility model relates to a kind of hard sealed valve device of pottery of transporting system, on industries such as oil, chemical industry, chemical fibre, oil refining, metallurgy, thermal power plant, nuclear power station, system uses on high temperature, the pressure duct, in the fed sheet of a media process, reduce abrasion, ensured its sealing effect, be a kind ofly wear-resistingly, corrosion-resistant, anti-wash away, the hard sealed stop valve of pottery that sealing is strong.
Background technique:
At present, the structure of known stop valve is by final controlling element, metal valve stem, the metal flap, valve body or the like assemblies, the stop valve medium is an one-way flow, directivity is arranged, and medium has transporting velocity faster, to the metal flap, the erosion abrasion of metal valve body are serious, cause sealing poor, working life is shorter, needs frequent the parking to change the metal flap and repair metal seat valve, and stop valve belongs to forced seal formula valve, so when valve closing, must exert pressure, not leak with forced seal face to flap, valve operation inconvenience, the cost height causes manufacturing efficiency low, the situation that cost of production has high input.
Summary of the invention:
In order to overcome existing stop valve abrasion; wash away fast; life-span is short and operate the deficiency that constitutes a threat to such as dumb; this use is novel to provide a kind of pottery hard sealed stop valve; select different valve body materials for use; can be applicable to water respectively; steam; oil product; nitric acid; acetic acid; Oxidant; multiple medium such as urea; when medium is gas (small-bore stop valve); fluid resistance is used to contain solid particle or the big fluid of viscosity hour more during liquid; fluid resistance is difficult for being used in when big and contains solid particle or the big fluid of viscosity; it is a kind of valve of good airproof performance; the hard sealed stop valve of this pottery not only wears away little; wear-resistant; anti-washing away; corrosion-resistant; and sealing is strong; long service life; this valve mechanism is simple, flexible operation.
The technological scheme that its technical problem that solves the utility model adopts is: in valve body, the outer final controlling element of establishing of metal flap and ceramic seal spare connects the work done of spiral valve rod driving valve, be a kind of wear-resisting, anti-washing away, high temperature resistant, corrosion resistant valve, drive the unlatching that the metal flap is realized valve by final controlling element, close, valve body, valve rod, flap is a metal material, ceramic valve seat, ceramic seal spare adopts the industrial ceramics material, sealing means adopts and is sealed and matched firmly, ceramic valve seat adopts hot charging to cooperate with metal valve body in valve body, ceramic valve seat closes with ceramic seal spare on being embedded in the metal flap and cooperates, metal valve body is connected by valve rod with the metal flap, valve body arranged outside one final controlling element, metal valve body is outside, and (the final controlling element executive mode can be: pneumatic by the fixedly connected final controlling element of valve rod, electronic, manually etc.), final controlling element drives the metal flap by metal valve stem and ceramic seal spare moves up and down work done, realize opening of ceramic stop valve, close, the pottery stop valve has prolonged the working life of valve greatly, ceramic valve seat is that industrial ceramics cooperates with metal valve body heat insert and forms, ceramic seal spare and metal flap drive fit, because being hard sealing, the sealing means of the ceramic seal spare on ceramic valve seat and the metal flap closes drive fit, can obtain desirable sealing effect, because valve contacts the industrial ceramics that local material is the superhard wear consumption with medium, can alleviate slurries greatly, particle, liquid and other medium is to the erosion wear intensity of valve, and it is little to reach abrasion, the purpose of long service life.
The beneficial effects of the utility model are: the fit system that adopts the hard sealing of pottery, sealing is tight, reduce abrasion, handwheel, executive mode such as pneumatic, electronic operation can be set outward, move up and down work done by related valve rod drive metal flap of final controlling element and ceramic seal spare, realize valve unlatching, close, it is simple in structure, flexible operation.
