Abstract
The utility model relates to a wear resistant sluice valve which comprises a valve body, a valve base, a flashboard, a valve rod, a transmission mechanism, a sealing piece and a mounting piece, wherein the flashboard adopts a double-flashboard structure through a left flashboard and a right flashboard, and principally, the flashboard is lined with a ceramic sealing surface; and the inner wall of a channel of the valve body is lined with a ceramic layer. The wear resistant sluice valve improves corrosion resistance and wear resistance, and has the advantages of good sealing performance, long service life and the like. And the valve is suitable for the working condition of abrasive medium.
Description
Technical field
The utility model relates to valve field, and particularly about a kind of double-flashboard gate valve, the utility model is applicable to abrasiveness medium operating mode.
Background technique
Double-flashboard gate valve generally is comprised of valve body, valve seat, flashboard, valve rod, driving mechanism, flashboard adopts the symmetrical double-flashboard structure that is connected to the valve rod both sides, its major defect is that flashboard and valve base sealing surface wear are more serious, affect sealability and working life when abrasiveness medium operating mode is used.
Summary of the invention
The purpose of this utility model is the shortcoming that exists for prior art, and the wear-resistant sluice valve of a kind of wear-resistant, good seal performance, long service life is provided.
The technical solution of the utility model comprises valve body, valve seat, flashboard, valve rod, driving mechanism, Sealing and assembling set, and flashboard forms the double-flashboard structure by left flashboard and right flashboard, mainly is flashboard lining ceramic seal face, wall liner ceramic layer in the valve channel.
In above technological scheme, valve body adopts three stage structure, is connected by bolt respectively between left valve barrel and right valve barrel and the middle valve body, and the sealing surface of both sides valve seat and left valve barrel and right valve barrel inboard are on the plane.
In above technological scheme, left flashboard and right flashboard are installed on the contiguous block, be fixedly connected with the valve rod lower end in the middle of the contiguous block, the contiguous block both sides are shaped with cylindrical body, left flashboard and right flashboard movable set are on the cylindrical body of contiguous block both sides, the cylindrical body center is shaped with through hole, mounting spring in this through hole, and the two ends of spring are fitted in the center, the back side of left flashboard and right flashboard.
The utility model has the advantages that flow passage components lining stupalith, improved corrosion resistant, wear-resisting property, good seal performance, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Wear-resistant sluice valve as shown in Figure 1, comprise valve body, valve seat, flashboard, valve rod 4, driving mechanism, Sealing and assembling set, flashboard forms the double-flashboard structure by left flashboard 5 and right flashboard 7, flashboard lining ceramic seal face, wall liner ceramic layer in the valve channel has corrosion resistant, the characteristics such as wear-resisting.
Valve body adopts three stage structure, be connected by bolt respectively between left valve barrel 3 and right valve barrel 2 and the middle valve body 1, the sealing surface of both sides valve seat and left valve barrel 3 and right valve barrel 2 inboards are on the plane, and left valve barrel 3 and right valve barrel 2 inner side plane play the guiding role in the flashboard uphill process, prevent that flashboard from coming off.
Left flashboard 5 and right flashboard 7 are installed on the contiguous block 6, be fixedly connected with valve rod 4 lower ends in the middle of the contiguous block 6, contiguous block 6 both sides are shaped with cylindrical body, left flashboard 5 and right flashboard 7 movable sets are on the cylindrical body of contiguous block 6 both sides, the cylindrical body center is shaped with through hole, and mounting spring 8 in this through hole, and the two ends of spring 8 are fitted in the center, the back side of left flashboard 5 and right flashboard 7, provide the power that struts to left flashboard 5 and right flashboard 7, make flashboard and valve seat keep sealing to contact.Can rotate at cylindrical body in the flashboard opening-closing process, automatically carry out wear compensation.
