The sluice valve is formed by the two valve bodies in the fixing mode through the bolts, diameters on the two sides of a shell through hole are made to be the same, and therefore flowing directions of fluid do not need to be considered when pipelines are installed; the two sides walls of the valve plate are respectively provided with an elastic rubber layer, a second ceramic plate is arranged on each elastic rubber layer, the inner walls on the two sides of the valve spool are provided with first ceramic plates communicated with the valve through holes, therefore, sealing effect is better, and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of complete ceramic-lined knife gate valve that has.
Background technique
Traditional flat knife gate valve has such two characteristics at present: 1, the housing latus rectum is that a side is large, and a side is little, and flow direction is to flow from heavy caliber to small-bore direction during installation, considers like this flow direction problem of fluid when pipeline is installed with regard to needs; 2, one-sided forced seal is adopted in the sealing of valve plate and housing, and opposite side then adopts welding block technology to be used for forcing the extruding valve plate; Itself and opposite side are sealed.Just because of this, plate valve in the past can only be inlayed mosaic when latus rectum place edge pottery, it is the block that welding is arranged in the heavy caliber, poor sealing performance, perishable, working life is low, if fluid is fine-powdered, and flow velocity is fast, when abrasive forces is strong again, knife gate valve in the past can very easily wear and tear, and then causes and can not use.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of complete ceramic-lined knife gate valve that has simple in structure, easy to use.
Of the present utility model have a complete ceramic-lined knife gate valve, comprise cylinder, support and housing, described housing is bolted by two valve bodies and forms, the contacting point of two valve bodies is by the high density rubber seal, have the valve through hole of mutual perforation on the sidewall of two valve bodies, be provided with the valve pool that mutually connects with the valve through hole between two valve bodies, the inside of valve pool is provided with valve plate, valve plate is provided with the valve plate through hole that matches with the valve through hole, the top of housing is bolted valve gap, and the top of valve plate connects valve rod, and the top of valve rod connects cylinder column by connecting head, the top of cylinder column connects cylinder, and cylinder is fixed on the housing by support.
Of the present utility model have a complete ceramic-lined knife gate valve, and the inwall of described valve through hole is provided with two symmetrical stoneware pipes.
Of the present utility model have a complete ceramic-lined knife gate valve, is equipped with the first ceramic plate that connects with the valve through hole on the both sides inwall of described valve pool.
Of the present utility model have a complete ceramic-lined knife gate valve, is respectively equipped with elastic rubber layer on the two side of described valve plate, and the outside of elastic rubber layer is equipped with one deck the second ceramic plate.
Compared with prior art the beneficial effects of the utility model are: of the present utility model to have a complete ceramic-lined knife gate valve simple in structure, housing is bolted by two valve bodies and forms, housing through-hole is made both sides with the footpath, when pipeline is installed, just not be used in the flow direction problem of considering fluid like this; Be respectively equipped with elastic rubber layer on the two side of valve plate, and at elastic rubber layer the second ceramic plate be set, be equipped with the first ceramic plate that connects with the valve through hole on the both sides inwall of valve pool, sealing effect is better; When inlaying stoneware pipe in the valve through hole, can not use again mosaic, owing to do not had the block of welding on the latus rectum, so we have adopted the edge whole ceramic tube at both sides latus rectum place; Because pottery is wear-resisting than stainless steel, thus it can use in the medium of fine-powdered, and be fit to use at flow velocity very fast also very easily in the operating mode of wearing and tearing, thereby make valve prolong working life.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As Figure 1-3, a kind of have a complete ceramic-lined knife gate valve, comprise cylinder 1, support 2 and housing 3, described housing 3 is bolted by two valve bodies and forms, the contacting point of two valve bodies is by the high density rubber seal, have the valve through hole 4 of mutual perforation on the sidewall of two valve bodies, be provided with the valve pool 5 that mutually connects with valve through hole 4 between two valve bodies, the inside of valve pool 5 is provided with valve plate 6, valve plate 6 is provided with the valve plate through hole 7 that matches with valve through hole 4, the top of housing 3 is bolted valve gap 8, valve gap 8 underlay rubber pads, the top of valve plate 6 connects valve rod 9, and the top of valve rod 9 connects cylinder column by connecting head 10, the top of cylinder column connects cylinder 1, and cylinder 1 is fixed on the housing 3 by support 2.
Of the present utility model have a complete ceramic-lined knife gate valve, and the inwall of described valve through hole 4 is provided with two symmetrical stoneware pipes 11.
