Abstract
The utility model relates to a valve plate for a rubber gate valve with a wear-resistance guide rail. The valve plate comprises a full rubber covering rubber valve plate, wherein a rubber layer is covered on a valve plate framework, and the two sides of the valve plate are respectively provided with U-shaped cross section guide rails capable of vertically sliding along chutes arranged at two sides inside a valve body of the rubber gate valve. The valve plate is characterized in that U-shaped cross section guide rail wear-resistance elements which are matched with the guide rails and are vulcanized into a whole as the guide rails are respectively buried and arranged into the guide rails arranged at two sides of the valve plate, the sliding surfaces of the guide rail wear-resistance elements are exposed out of the surfaces of the U-shaped cross section guide rails, rubber covering convex edges are arranged at the bottom of the outer side of the U-shaped cross section guide rail wear-resistance elements, rubber covering grooves are correspondingly arranged on the valve plate framework, and the U-shaped cross section guide rail wear-resistance elements are made of wear-resistance plastics. The valve plate has the beneficial effects that the mechanical intensity of the guide rails is improved, so the guide rails cannot be easily abraded, the integral service lives of the valve plate and the guide rails are prolonged, and the sealing performance of the gate valve is improved.
Description
Technical field
The utility model relates to a kind of rubber valve parts, relates in particular to a kind of rubber valve valve plate with wear-resisting guide rail.
Background technique
Gate valve is indispensable control apparatus in water system, is mainly used in pipe network, pump house and filter tank etc. and locates.Gate valve is a kind of of block valve class, is used for connecting or block the medium in pipeline, usually is applicable to not need often to open and close and keep the operating mode of valve plate standard-sized sheet or full cut-off.Gate valve mainly comprises valve body, valve gap, valve rod, the valve plate that is connected with valve rod, valve seat and filler assembly.Valve body is the main body of gate valve, is the strength member that connects valve gap, installation valve plate slideway, lays valve seat, connecting tube.The open-shut device of gate valve is valve plate, moving direction and the flow direction of valve plate are perpendicular, valve rod is connected with Stem Mut or transmission device, play a part carry-over moment and open and close valve plate, valve plate is done elevating movement by the slide rail of its dual-side setting along the valve body slideway and is reached the keying purpose under the drive of valve rod.At present, the soft sealing gate valve that employing coated glue-line on the valve plate skeleton forms full rubber-covered valve plate becomes the industry development main flow, rubber valve adopts the full encapsulate of valve plate directly contact the form of sealing with valve body, and the rubber channel section guide rail of rubber-covered valve plate by its dual-side setting moves up and down along the slideway of body cavity both sides correspondence setting and realize valve opening or close.But the shortcoming that this structure exists is: the rubber valve valve plate moves back and forth along slideway, produces friction with valve body, and because intensity, the wear resistance of rubber are relatively poor, therefore very easily wearing and tearing make the valve plate life-span reduce.
The model utility content
Main purpose of the present utility model is for the problems referred to above, and a kind of rubber valve valve plate with wear-resisting guide rail is provided, and strengthens the mechanical strength of valve plate guide rail, extends the working life of valve plate.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of rubber valve valve plate with wear-resisting guide rail, be included in the full rubber-covered valve plate of coated glue-line on the valve plate skeleton, described valve plate both sides are respectively equipped with the channel section guide rail that slides up and down along two side slideways in the rubber valve valve body, it is characterized in that burying underground respectively in valve plate two side rails and described guide rail and the channel section guide rail wearing piece that is integrated with its sulfuration, the planing surface of described guide rail wearing piece is exposed to the channel section guide rail surface.
The bottom in the described channel section guide rail wearing piece outside arranges the encapsulate fin, and correspondence arranges the encapsulate groove on described valve plate skeleton.
The material of described channel section guide rail wearing piece is wear-resistant plastic.
The beneficial effects of the utility model are: form wear-resisting guide rail owing to having set up the guide rail wearing piece on valve plate two side rails; when valve plate slides up and down along the valve body slideway; slideway contacts with guide rail wearing piece direct friction; in addition; the wear-resistant plastic that the guide rail wearing piece has adopted polyoxymethylene, teflon etc. to have strong wear resistance; thereby improved the mechanical strength of guide rail; make it not easy to wear; also protected valve plate; extend valve plate and guide rail whole service life, adopted this structure also to improve the sealability of gate valve.
