Abstract
The utility model relates to a ceramic hard sealing dome valve in an ash transportation system of a power plant. In a valve body in the utility model, a ceramic sealing ring is in interference hot charging at the top of the valve body, a ceramic ball dome and a tumbler shaft are fixedly assembled, an electric actuator is arranged and is connected with a tumbler, and the switching position limit of the dome valve is controlled by operation. The ceramic ball dome and the ceramic sealing ring are in spherical hard sealing fit, which ensures good sealing effect. Because the ceramic ball dome and the ceramic sealing ring adopt ultra-hard wear-proof industrial ceramics, the eroding and wearing degree of materials to the ceramic ball dome and the ceramic sealing ring can be greatly relieved, and the service life of the dome valve is prolonged.
Description
Affiliated technical field:
The pottery that the utility model relates to a kind of transporting system reduces the hard O-ring overhead-valve of pottery that abrasion ensure sealing effect and release Pneumatic actuator in sealed valve device, especially the fly ash in electric power plant course of conveying firmly.
Background technique:
At present, the structure of known pneumatic transport dome valve is to be assemblied by inflation cylinder, transmission cylinder, tumbler shaft, Metal Ball top, valve body, metallic gasket, rubber seal, support ring, top board, opening the inflation cylinder is rubber seal inflation and the sealing of Metal Ball top, and inner gas pressure is greater than the pressure that material produces, after material is full of, close the inflation cylinder, start the transmission cylinder, the operation tumbler shaft rotates the Metal Ball top, switch to the opening state of dome valve, material is carried from dome valve passed through, this process circulates successively.Owing to transporting velocity is faster arranged by material, erosion abrasion to Metal Ball top and rubber seal are serious, working life is shorter, needing frequent parking more to change the shuttle pushes up and seal ring, and the Pneumatic actuator volume is big, complex structure, operation inconvenience, cost height, causes the situation that manufacturing efficiency is low, cost of production has high input.
Summary of the invention:
Existing dome valve abrasion are fast, the life-span is short and operate inflexible deficiency in order to overcome, this use is novel to provide a kind of pottery hard O-ring overhead-valve, the hard O-ring overhead-valve of this pottery not only wears away little, long service life, and parts such as complicated Pneumatic actuator and support ring, top board, metallic gasket have been reduced, structure is simple, flexible operation.
The technological scheme that its technical problem that solves the utility model adopts is: ceramic seal circle and valve body top interference hot charging are joined in valve body, the ceramic ball top, tumbler shaft is linked and packed, one electric actuator is set, tumbler shaft one end and electric actuator are linked and packed, when electric actuator operation tumbler shaft makes the ceramic ball top turn to the contract fully sealing, can be to the feed bin charging until being full of, again rotation an angle of 90 degrees in ceramic ball top is full-gear, material is carried from dome valve to be passed through, the rotation process of final controlling element operation pivoted arm can the spacing switching of complete realization ceramic ball top from the standard-sized sheet to the full cut-off, because the ceramic ball top is spherical airtight drive fit with the sealing means of ceramic seal circle, can obtain desirable sealing effect, adopting material is the industrial ceramics of superhard wear consumption, ceramic ball top is inlayed for metal frame and ceramic sphere and is formed, can alleviate the pulverized fuel ash material greatly pushes up ceramic ball, the erosion wear intensity of ceramic seal circle, it is little to reach abrasion, the purpose of long service life.
The beneficial effects of the utility model are: adopt the mode of the hard sealing of pottery, sealing is tight, reduces abrasion, the switching of final controlling element operation dome valve is set, cancelled parts such as original Pneumatic actuator and metallic gasket, top board, support ring, simple in structure, flexible operation.
