Abstract
The utility model relates to a pressure-resistant corrosion-resistant composite butterfly valve which comprises a valve body 1, a valve board 2, a valve shaft 3 and a handle 4, wherein the valve body 1 is in an integral mould pressing structure, the valve board 2 and the valve shaft 3 are integrally formed by mould pressing, and the inner surface and the outer surface are both coated with fiber protective layers 12 of glass fiber reinforced plastics. The utility model is not provided with fastening components, has no gaps, and can not be eroded by corrosive substances. Meanwhile, the intensity of the valve shaft 3 is increased and the flowing area in a pipeline is increased. Thus, the utility model has the advantages of large flow, firmness, high durability and good corrosion resistance.
Description
The utility model relates to that fixed buildings is given, the draining class, particularly the withstand voltage corrosion-resistant compound butterfly valve that uses in the corrosion thing conveyance conduit.
Anticorrosion valve of the prior art, valve plate is fixed on the valve shaft by fastening piece, and the aisle spare in the pipeline is reduced, and influences flow.Valve body is formed by several component-assembled, although scribble anticorrosive coat with corrosion thing contact surface, corrodes thing and still can corrode fastening piece the slit between parts, influences the working life of anticorrosion valve.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art, and the withstand voltage corrosion-resistant compound butterfly valve of big, the sturdy and durable and favorable anti-corrosion effect of a kind of flow is provided for people.
The utility model is realized by implementing following technological scheme, and a kind of withstand voltage corrosion-resistant compound butterfly valve comprises valve body, is installed in wherein valve plate, passes valve shaft that valve body is connected with valve plate and the handle that is contained in its outer end.Valve body is the integral die structure, and at inner liner metal skeleton inner and outer surface cover glass Steel Fibre protective layer, valve plate and valve shaft are the one die formings, and its surface is coated with the reinforced plastic glass fibre protective layer equally.The part of valve shaft in valve body is the bent axle shape that crank throw is arranged; valve plate is connected a side of valve shaft; its surface is for flowing to type, and the surface coverage of handle has the reinforced plastic glass fibre protective layer, and to be embedded with the surface that a circle tetrafluoroethylene makes be the recessed seal ring of sphere to a side in the valve body.Because valve body, valve shaft and valve plate are that integral die moulding and surface coverage have the reinforced plastic glass fibre protective layer, do not have fastening piece and slit, so the corrosion thing can not corrode.Valve plate and valve shaft are one, and the valve plate surface flows to type, can increase its intensity, can add the circulation area in the large pipeline simultaneously.Valve shaft is the bent axle shape, is embedded with the surface in the valve body and is the recessed seal ring of sphere.When throttle down, because the effect of crank throw, valve shaft is pressed to valve plate seal ring and is made both driving fits, and has avoided the wear and leakage that the interference crush seal is caused in the conventional valves.Even seal ring produces compressive strain, the valve shaft that has crank throw can make valve plate and seal ring driving fit equally.The surface coverage of handle has the reinforced plastic glass fibre protective layer, makes can not be corroded thing corrosion of handle.
Further describe the most preferred embodiment of the utility model below in conjunction with accompanying drawing.
Fig. 1 is that the master of the withstand voltage corrosion-resistant compound butterfly valve of the utility model looks cross-sectional schematic (valve plate opening state).
Fig. 2 is that withstand voltage corrosion-resistant compound butterfly valve master looks cross-sectional schematic (valve plate closed condition).
Fig. 3 is that withstand voltage corrosion-resistant compound butterfly valve is overlooked cross-sectional schematic.
Can find out that from Fig. 1, Fig. 2 a kind of withstand voltage corrosion-resistant compound butterfly valve comprises valve body 1, is installed in wherein valve plate 2, passes valve shaft 3 that valve body 1 is connected with valve plate 2 and the handle 4 that is contained in its outer end.Described valve body 1 is the integral die structure, and at inner liner metal skeleton 11 inner and outer surface cover glass Steel Fibre protective layers 12, described valve plate 2 is one die formings with valve shaft 3, and its surface is coated with reinforced plastic glass fibre protective layer 22 and 32 equally.Because valve body 1, valve shaft 3 and valve plate 2 are that integral die moulding and surface coverage have reinforced plastic glass fibre protective layer 12,22 and 32, do not have fastening piece and slit, can not corrode so corrode thing, and increase the intensity of valve shaft 3.
Can find out that from Fig. 2, Fig. 3 the part of described valve shaft 3 in valve body 1 is the bent axle shape that crank throw is arranged, described valve plate 2 is connected a side of valve shaft 3, and its surface is for flowing to type, and the mobile while that helps medium can add the circulation area in the large pipeline.To be embedded with the surface that a circle tetrafluoroethylene makes be the recessed seal ring 13 of sphere to a side in the described valve body 1.Valve shaft 3 is bent axle shapes, when throttle down, because the effect of crank throw, valve shaft 3 is pressed to valve plate 2 seal ring 13 and is made both driving fits, avoided the wear and leakage that the interference crush seal is caused in the conventional valves, even seal ring 13 produces compressive strain, the valve shaft 3 that has crank throw can make valve plate 2 and seal ring 13 driving fits equally.
As can be seen from Figure 1, the surface coverage of described handle 4 has reinforced plastic glass fibre protective layer 42, makes can not be corroded thing corrosion of handle.
By implementing technique scheme, make to the utlity model has the characteristics of big, the sturdy and durable and favorable anti-corrosion effect of flow.
