Including valve body, valve gap, valve rod and flashboard, the valve body runner has in the valve body, the valve plate downside is provided with and cleans the subassembly, clean the subassembly including fixing the fixed axle of valve plate downside and consolidate the fixed plate that fixed axis rotation is connected with this, the fixed plate side evenly is provided with a plurality of arc pieces, the fixed plate downside is seted up flutedly, sliding connection has the connecting plate in the recess, on the connecting plate side with be provided with the spring between the recessed wall, the connecting plate downside is provided with the brush hair, the coating of valve body flow surface has the polyurethane layer, just is in be provided with wear -resisting retaining ring in the valve body runner. The utility model discloses can be when the gate valve be closed, along with the subassembly is cleaned in the operation of fluidic impulsive force, automatic impurity to below the flashboard cleans, and the assurance flashboard can cut out and target in place, guarantees the leakproofness of gate valve.
Description
Technical field
The utility model relates to a kind of wear-resisting double-flashboard gate valve.
Background technique
Gate valve is widely used in the fields such as chemical industry, metallurgy, hydraulic engineering, and existing gate valve, when gate valve is opened, flashboard rises, flowing medium flows out, but when containing more impurity in flowing medium, impurity easily recess accumulation below flashboard, when gate valve is closed, impurity alluvial cannot be discharged in time, is easily attached on sealing surface, blocking flashboard passage, flashboard can not cut out put in place, reduce the sealing of gate valve.
Summary of the invention
The utility model, for deficiency of the prior art, provides a kind of wear-resisting double-flashboard gate valve, and it can when gate valve be closed, impulse force along with fluid runs cleaning assembly, automatically the impurity below flashboard is cleaned, ensure that flashboard can cut out and put in place, ensure the sealing of gate valve.
For solving the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of wear-resisting double-flashboard gate valve, comprise valve body, valve gap, valve rod and flashboard, in described valve body, there is valve flowing channel, described valve plate downside is provided with cleaning assembly, described cleaning assembly comprises the stationary axle being fixed on described valve plate downside and the fixed plate be rotationally connected with this stationary axle, described fixed plate side is evenly provided with some arc-like sheets, described fixed plate downside offers groove, connecting plate is slidably connected in described groove, spring is provided with between described connecting plate upper side and described groove inner wall, described connecting plate downside is provided with bristle, described valve flowing channel surface is coated with polyurethane layer, and wear-resisting retaining ring is provided with in described valve flowing channel.
When valve plate rises, when gate valve is opened, because fixed plate is rotatably connected on stationary axle, and be flushed on arc-like sheet and fixed plate side along with fluid, fixed plate is rotated, during rotation, can form whirlpool below valve plate, the impurity that a part is rested on below valve plate rises, and is flushed away; When valve plate declines, due to the rotation that fixed plate continues, when bristle contact is to impurity, the bristle be under rotation status cleans the impurity stopped, remaining impurity is cleaned out, thus flashboard can cut out put in place, and due to the effect of spring, make bristle along with connecting plate upper and lower displacement while rotation, can clean impurity faster.
In technique scheme, preferably, described fixed plate side is circular arc.The effect of circular arc side is when fluid rushes at fixed plate, facilitates fixed plate to rotate.
In technique scheme, preferably, the concave surface of all described arc-like sheets is all towards described fixed plate.Make the action direction of arc-like sheet consistent, be convenient to fixed plate and rotate.
In technique scheme, preferably, described wear ring material is cemented carbide
The beneficial effects of the utility model are: the utility model can when gate valve be closed, and the impulse force along with fluid runs cleaning assembly, automatically cleans the impurity below flashboard, ensure that flashboard can cut out and put in place, ensure the sealing of gate valve.
Accompanying drawing explanation
Fig. 1 is the utility model schematic cross-section.
Fig. 2 is D place enlarged diagram in Fig. 1.
Fig. 3 is the schematic cross-section after the utility model fixed plate is separated with connecting plate.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: see Fig. 1-Fig. 3, a kind of wear-resisting double-flashboard gate valve, comprise valve body 1, valve gap 2, valve rod 3 and flashboard 4, in described valve body 1, there is valve flowing channel 11, described valve plate 4 downside is provided with cleaning assembly, described cleaning assembly comprises the stationary axle 41 being fixed on described valve plate 4 downside and the fixed plate 42 be rotationally connected with this stationary axle 41, described fixed plate 42 side is evenly provided with some arc-like sheets 43, described fixed plate 42 downside offers groove 44, connecting plate 45 is slidably connected in described groove 44, spring 46 is provided with between described connecting plate 45 upper side and described groove 44 inwall, described connecting plate 45 downside is provided with bristle 47, described valve flowing channel 11 surface is coated with polyurethane layer, and wear-resisting retaining ring is provided with in described valve flowing channel 11, described wear ring material is cemented carbide, also can be polytetrafluoroethylmaterial material, or zirconium oxide matrix wear-resistant ceramic, alumina base wear-resistant ceramic, silicon carbide-based wear-resistant ceramic, mullite wear-resistant ceramic, be oxidized any one making in silica-based wear-resistant ceramic.
Described fixed plate 42 side is circular arc.The effect of circular arc side is when fluid rushes at fixed plate, facilitates fixed plate to rotate.
The concave surface of all described arc-like sheets 43 is all towards described fixed plate 42.Make the action direction of arc-like sheet consistent, be convenient to fixed plate and rotate.
When valve plate rises, when gate valve is opened, because fixed plate is rotatably connected on stationary axle, and be flushed on arc-like sheet and fixed plate side along with fluid, fixed plate is rotated, during rotation, can form whirlpool below valve plate, the impurity that a part is rested on below valve plate rises, and is flushed away; When valve plate declines, due to the rotation that fixed plate continues, when bristle contact is to impurity, the bristle be under rotation status cleans the impurity stopped, remaining impurity is cleaned out, thus flashboard can cut out put in place, and due to the effect of spring, make bristle along with connecting plate upper and lower displacement while rotation, can clean impurity faster.
