Abstract
The utility model relates to a flat gate valve for slag mud, belonging to general machinery, comprising a main valve body, an auxiliary valve body, a valve plate, a valve rod, a valve cover, a handwheel, etc. The utility model has the advantages of simple structure, easy processing, low maintenance cost, good sealing performance and long service life.
Description
The utility model is to be used to carry work the special valve that opens and closes control action on breeze, lime-ash, the mud medium pipeline.
At present, this slag mud plate valve of use, valve body is divided into main valve body, auxiliary valve body.Valve seals directly is embedded on the major and minor valve body, ring wear, whole valve has just been scrapped, and increases maintenance expenses.The structure of flashboard is the bottom of through hole at flashboard, and this structural type is when opening flashboard, and a large amount of slags or mud medium just are full of particularly valve body cavity of resorption of whole valve pocket.Flashboard and valve body sealing surface abrade easily in opening-closing process, cause the valve well damage to influence the working life of valve.
The purpose of this utility model provide a kind of valve body sealing surface can change easily, easy to process, maintenance expenses is low, slag mud is difficult for entering the valve body cavity of resorption, reduce the slag mud plate valve of sealing surface scratch chance, long service life.
The utility model is achieved in that valve body is oblate, is made up of main valve body and auxiliary valve body.Valve seat and valve body are movingly, mounting or dismounting are changed convenient, valve seat and valve body interior edge face contacting point are equipped with O type circle and guarantee valve seat and valve seal, be processed with seal groove on the valve seat, in seal groove, be inlaid with seal ring, and on valve seat, also there are directly to process metallic sealing section the metallic sealing section on formation seal ring and flashboard, the valve seat and the double seal of flashboard.Valve seat gives tight power and can be adjusted by the spacer of auxiliary valve body, guarantees sealing.Flashboard is a rectangular flat plate, and flashboard left a through hole that equates with latus rectum by original changing into from the below perforate from the top.This flashboard structure, can avoid or greatly reduce valve slag or mud medium in opening-closing process entering the main valve body cavity of resorption and reducing the chance that sealing surface scratches, prolong valve working life, valve rod adopts T-slot to be connected with valve plate, reliable convenient, handwheel drives the Stem Mut rotation, valve rod is moved up and down, switch valve.Round nut plays position-limiting action, aligns with passage in assurance flashboard hole.
The outstanding feature of the utility model is to be inlaid with two removable valve seats on the valve body, and is easy to process, when sealing surface scratches, replaceable valve seat and can not make that whole valve is scrapped, maintenance expenses is low.During valve wide open, particle media flows and directly not to wash away valve sealing face, and the slag particle thing do not fall into the valve body bottom, and sealing surface is difficult for scratch, thereby reaches the effect of long service life, good seal performance.
Now in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the utility model sealing vice division chief partial enlarged drawing.
Fig. 1～2nd, a kind of specific embodiment of the utility model.Earlier nonmetal seal ring 8 is packed in the valve seat 6, with O type circle 7 main valve body 1 of packing into, auxiliary valve body 2 interior edge faces are contained in two valve seats 6 respectively in the valve support chamber of main valve body 1, auxiliary valve body 2, are processed with seal groove on the valve seat 6, are inlaid with nonmetal seal ring 8 in the seal groove.In main valve body 1, auxiliary valve body 2 and valve seat 6 contacting points " O " RunddichtringO 7 that seals is installed, again spacer 9 be placed on adjust between main valve body 1 and the auxiliary valve body 2 after, the usefulness fastening piece is steady.Valve plate 3 is packed in the valve body chamber, valve rod 14 is packed in the flashboard T-slot, again pad 12 is placed on flange place in the main valve body 1, buckle with the valve gap 13 usefulness fastening pieces handle of support one tight, then handwheel 22 is contained on the valve rod 14, with gland nut 24 that handwheel 22 is fastening, then stop nut 25 is mixed up.On main valve body 1, auxiliary valve body 2, adopt removable valve seat movingly.When the sealing surface on the valve seat 6 abrades, open valve, the valve seat that more renews, valve can continue to use and can not make whole valve scrap, reduce user's maintenance expenses, will be original on flashboard 3 change into open a medium through hole that equates with latus rectum above flashboard opening medium through hole below the flashboard.The utility model is compared with present slag particle mud plate valve has the advantages that particle media flows and directly do not wash away valve sealing face, particulate matter can not fall into the cavity of resorption bottom of main valve body 1 and avoid or greatly reduce sealing surface abrading chance, thereby reaches the purpose of long service life, good seal performance.
Claims (2)
1, a kind of slag mud plate valve, be that auxiliary valve body 2 usefulness fastening pieces dress is firm on main valve body 1, flashboard 3 is packed in the valve body chamber, valve rod 14 is packed in the flashboard T-slot, pad 12 is contained in flange place in the main valve body 1, loads onto the valve gap 13 with the support one, and it is characterized in that: a medium through hole that equates with latus rectum is opened in the top of valve plate 14, on main valve body 1, auxiliary valve body 2, be inlaid with two removable movable valve seats 6, be inlaid with seal ring 8 on the valve seat 6.
2, according to the slag mud plate valve described in the claim 1, it is characterized in that: be processed with the seal groove of inlaying seal ring 8 on the valve seat 6.
