Abstract
The utility model discloses an eccentric linear type wear-resistant dust-laden gas butterfly valve, which comprises a valve body. A valve shaft is arranged in the valve body, a disc arranged on the valve shaft inside the valve body consists of a small circle side and a large circle side, a semicircular arc-shaped wear-resistant liner engaged with the inner wall of the valve body is fixedly arranged in the valve body, a first valve seat and a second valve seat are respectively fixedly arranged on the inner wall of the semicircular arc-shaped wear-resistant liner and the inner wall on one side of the valve body, the small circle side and the large circle side of the disc are respectively engaged with the first valve seat and the second valve seat, a first clearance is formed between the end of the small circle side of the disc and the inner wall of the semicircular arc-shaped wear-resistant linear, and a second clearance is formed between the end of the large circle side of the disc and the inner wall of the valve body. The eccentric liner type wear-resistant dust-laden gas butterfly valve has the advantages that the butterfly valve utilizes an asymmetrical disc structure and an asymmetrical valve body structure to replace the conventional symmetrical structure, is simple in structure, reasonable in material arrangement and simple and practicable in processes, saves cost, prolongs service life of the valve body and keeps original sealing property.
Description
Technical field
The utility model relates to a kind of dust and gas butterfly valve, relates in particular to a kind of bias lining type wear resistant dust and gas butterfly valve.
Background technique
Dust and gas butterfly valve usually is used to recovery, exchange, dedusting and waste heat recycling of blast furnace gas in the iron and steel metallurgical industry.In order to regulate air quantity, butterfly plate often is in various opening angles position, when the opening angle of butterfly plate was spent less than 20, high speed dirt entraining air stream was stopped by butterfly plate, the offset straight line direction, directly rush at valve body, cause the body cavity part seriously to wash away, even ultrashort time wearing and tearing penetrate, to valve is scrapped in advance, the pipe network blowing-out stops production, in advance maintenance.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of simple in structure, working life long bias lining type wear resistant dust and gas butterfly valve.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: bias lining type wear resistant dust and gas butterfly valve, comprise: valve body, in valve body, be provided with valve shaft, valve body is provided with some mounting holes, the valve shaft of valve inner is provided with butterfly plate, butterfly plate is made up of butterfly plate roundlet side and butterfly plate great circle side, be provided with the semicircular arc abrasion-proof backing block that cooperatively interacts with valve interior wall at described valve body internal fixation, on the inwall of the inwall of semicircular arc abrasion-proof backing block and valve body one side, be set with first valve seat and second valve seat respectively, the butterfly plate roundlet side of butterfly plate and butterfly plate great circle side cooperatively interact with first valve seat and second valve seat respectively, between the end of the butterfly plate roundlet side of butterfly plate and semicircular arc abrasion-proof backing block inwall, leave first gap, between the end of butterfly plate great circle side and valve interior wall, leave second gap.
The utility model has the advantages that: the bias lining type wear resistant dust and gas butterfly valve of said structure, simple in structure, adopt asymmetric butterfly plate and asymmetric valve body structure, the symplex structure that replaces traditional common, the material rational deployment is saved cost, has prolonged the working life of valve body, original sealability is constant, and is simple for process.
Description of drawings
Fig. 1 is the structural representation of the utility model bias lining type wear resistant dust and gas butterfly valve.
Fig. 2 is the A-A direction sectional structure schematic representation of Fig. 1.
Among the figure: 1, valve body, 2, valve shaft, 3, mounting hole, 4, butterfly plate, 41, butterfly plate roundlet side, 42, butterfly plate great circle side, 5, the semicircular arc abrasion-proof backing block, 6, first valve seat, 7, second valve seat, 8, first gap, 9, second gap.
Embodiment
Describe particular content of the present utility model in detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, shown in Figure 2, bias lining type wear resistant dust and gas butterfly valve, comprise: valve body 1, in valve body 1, be provided with valve shaft 2, valve body 1 is provided with some mounting holes 3, the valve shaft 2 of valve body 1 inside is provided with butterfly plate 4, butterfly plate 4 is made up of butterfly plate roundlet side 41 and butterfly plate great circle side 42, be provided with the semicircular arc abrasion-proof backing block 5 that cooperatively interacts with valve body 1 inwall at described valve body 1 internal fixation, on the inwall of the inwall of semicircular arc abrasion-proof backing block 5 and valve body 1 one sides, be set with first valve seat 6 and second valve seat 7 respectively, the butterfly plate roundlet side 41 of butterfly plate 4 and butterfly plate great circle side 42 cooperatively interact with first valve seat 6 and second valve seat 7 respectively, between the end of the butterfly plate roundlet side 41 of butterfly plate 4 and semicircular arc abrasion-proof backing block 5 inwalls, leave first gap 8, between the end of butterfly plate great circle side 42 and valve body 1 inwall, leave second gap 9.
When the bias lining type wear resistant dust and gas butterfly valve of said structure is worked, when rising to block to the dirt gas medium, bias lining type wear resistant dust and gas butterfly valve does the time spent, butterfly plate 4 is located the complete shut-down position in valve body 1 inner chamber, first gap, 8 appropriateness between the end of butterfly plate roundlet side 41 and semicircular arc abrasion-proof backing block 5 inwalls, and it is identical mutually with first valve seat 6, second gap, 9 appropriateness between butterfly plate great circle side 42 and valve body 1 inwall, and identical mutually with first valve seat 7, guarantee the reliable seal action of butterfly valve; When bias lining type wear resistant dust and gas butterfly valve plays regulating action to dirt gas medium air-flow; rotary valve shaft 2; make butterfly plate 4 open arbitrary minute angle; the dirt air-flow acutely is flushed on semicircular arc abrasion-proof backing block 5 inwalls fast; protected valve body 1 inwall; make valve body 1 inwall avoid acutely washing away, prolonged the working life of valve body 1.
