Abstract
The utility model relates to a sealing changeable gate valve, particularly the improvement of the sealing structure of a valve plate and a valve body. The utility model is characterized in that a sealing valve core (2) is arranged between the valve plate (3) and the valve body (1). The sealing valve cover is fixed on the valve body. The contacting portion of the sealing valve core and the aperture of the inner side of the valve body is sealed by a sealing ring (4) and the contacting portion of the sealing valve core and the valve plate is in movable cooperation with sealing. The gate valve overcomes the defect of the direct sealing of the valve body and the gate plate of the prior gate valve with convenient assembly and disassembly and use cost decrease, particularly, when the gate valve appears leakage, the purpose can be done by only changing the valve plate and the valve core in cooperation to prevent the gate valve from being entirely discarded. The service life of the gate valve is prolonged.
Description
The utility model relates to a kind of gate valve, especially the improvement of flashboard and valve seal structure.
Gate valve generally is made up of parts such as valve body, loam cake, flashboard, elevating screw, handwheels, rotates handwheel, and the elevating screw rotation drives flashboard and moves up and down, and plays the effect of regulating flow and opening or closing valve.Whole gate valve be sealed with two places: the one, the sealing of loam cake and valve body is finished by seal ring.The 2nd, the sealing of the inboard contacting point of the bore of flashboard and valve body is by flashboard built-up welding stainless steel and the inboard contacting point built-up welding stainless steel of valve body bore, cooperate then to grind to clamp and repair, till not leaking, such sealing can only be joined a valve body by a flashboard, can not exchange.After using a period of time, because of wearing and tearing or other reason occur cooperating bad when causing gate valve to leak, often whole valve is scrapped.Even if prepare new flashboard again, grind again up to meeting the requirements, valve body must be dismantled and take away, just can finish, very inconvenient, especially, more difficult for the gate of oil field, chemical industry unit's heavy caliber, heaviness.
The gate valve that provides a kind of flashboard and valve seal spare to change is provided the utility model purpose, to solve the defective of above-mentioned gate valve.
Technical solutions of the utility model are to settle a sealed valve core between flashboard and valve body, realize the sealing of flashboard and the inboard bore of valve body by sealed valve core.In case flashboard occurs cooperating bad situation, as long as open loam cake, removes the sealed valve core and the flashboard that are fixed on the valve body, changes the flashboard and the sealed valve core that have cooperated then, reloads in the former valve body.This sealing configuration has overcome the flashboard of existing gate valve and the defective that valve body directly seals, have easy accessibility, improve work efficiency, do not need the whole gate valve of scrapping, reduce cost (cost of flashboard and sealed valve core slightly equal 20% that whole valve is worth) advantages such as working life that prolonged flashboard.
Further specify technology contents of the present utility model below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is the overall structure schematic representation that embodiment seals the commutativity gate valve.
Fig. 2 is the sealed valve core plan view that Fig. 1 seals the commutativity gate valve.
Fig. 3 is the left view of Fig. 2.
Fig. 4 is the plan view of Fig. 2.
By figure, present embodiment sealing commutativity gate valve comprises valve body (1), flashboard (3), valve gap (6), elevating screw (11) and rotates handwheel (10), between flashboard (3) and the valve body (1) sealed valve core (2) is arranged, sealed valve core (2) is fixed on the valve body (1), the inboard bore of sealed valve core and valve body contacting point seals with O RunddichtringO (4), and sealed valve core and flashboard contacting point are sealing movingly.Among the embodiment, one screw (12) is arranged at the bottom of sealed valve core, porose on the valve body corresponding site, by stretching screw (7) and seal washer (9) sealed valve core is pressed abd fixed in the valve body, at this moment, the O RunddichtringO is pressed on the contacting point of sealed valve core and the inboard bore of valve body, with sealed valve core and valve seal.During the valve assembling, earlier the O RunddichtringO is put into the seal groove of sealed valve core, pressing hole that red copper seal ring (9) passes valve body (1) bottom with stretching screw (7) is screwed into screw (12) sealed valve core (2) is pressed abd fixed in the valve body, until sealed valve core and the inboard bore of valve body contacting point good seal, flashboard (3) that will match with sealed valve core and elevating screw (11) and loam cake (6), seal ring (5) and valve body (1) get final product proper functioning with the fastening jail of screw then.When flashboard cooperates with sealed valve core when bad, open loam cake (6), back out stretching screw (7), can take out flashboard and sealed valve core, renew the flashboard and the sealed valve core of working good and get final product.For the retaining screw that prevents fastening loam cake and valve body gets rusty, can coat butter at the end of each screw, put plastics cover cap (8).
Claims (3)
1, a kind of sealing commutativity gate valve, comprise valve body (1), flashboard (3), valve gap (6), elevating screw (11) and rotation handwheel (10), it is characterized in that being provided with sealed valve core (2) between flashboard (3) and the valve body (1), sealed valve core (2) is fixed on the valve body (1), the inboard bore of sealed valve core and valve body contacting point seals with O RunddichtringO (4), and sealed valve core and flashboard contacting point are sealing movingly.
2, sealing commutativity gate valve according to claim 1 is characterized in that a screw (12) is arranged at the bottom of sealed valve core, and is porose on the valve body corresponding site, by stretching screw (7) and seal washer (9) sealed valve core is pressed abd fixed in the valve body (1).
3, sealing commutativity gate valve according to claim 1 is characterized in that the end of the fastening screw of valve body (1) and valve gap (6) is with plastics cover cap (8).
