Abstract
The utility model relates to a gate valve, in particular to a flat plate gate valve provided with a diversion outlet. The flat plate gate valve with the diversion outlet has a central push rod which is a double face wedge-shaped block and is interlocked with an operating screw. Two shutters are respectively fixed on two wedge-shaped rise blocks through bolts, a limiting sliding cavity is arranged axially on each wedge-shaped rise block, sliders which are arranged on the wedge-shaped faces of the double face wedge-shaped block are opposite to the limiting sliding cavities and are in sliding fit with the limiting sliding cavities, the two rise blocks are arranged on the two sides of the double face wedge-shaped block to relatively form the opening and closing mechanism of the gate valve mechanism together with the wedge-shaped faces. The structure adopts the wedge-shaped rise blocks and the double face wedge-shaped block to form the opening and closing mechanism, and the shutters are fixed on the wedge-shaped block through bolts; therefore, the shutters can not produce obvious position variance with better stability; the limiting sliding cavities and the sliders work together to form the lifting mechanism of the shutters which can effectively press the shutters due to the fit between the wedge-shaped faces, thereby having good integrity and sealing performance.
Description
Technical field
The utility model relates to a kind of gate valve, especially a kind of plate valve with pod apertures.
Background technique
In chemical industry, oil, rock gas, power plant, colliery, building; in the industry such as sewage treatment and light industry; the flashboard of gate valve commonly used is an one; and flashboard is up big and down small wedge shape; not only processing inconvenience; and owing to often have hard particles or other dirts in the ducted liquid medium; these dirts remain on the sealing surface of valve body; sealing surface is scratched; make the sealing effect variation and cause internal leakage; cause shorten greatly the working life of flashboard, and the normal wear of sealing surface can cause internal leakage owing to compensating also.
The patent No. is 200620122851.4 file, a kind of self-sealing gate valve with double flat shutter board of band pod apertures that can the automatic compensation sealing face is disclosed, comprise valve body, valve gap, the valve gap that is positioned at the top is provided with operation screw rod and operation handwheel, guillotine mechanism with operation screw rod interlock is arranged in establishing in the valve body, be provided with the sealing surface that matches with flashboard in the guillotine mechanism in the valve body, guillotine mechanism comprises two flashboard and center push rod of separating mutually, two flashboards are evenly equipped with several stage clips on the inboard surface, the inboard draw-in groove that be provided with and that this lower end is complementary of the hermetic unit of center push rod by its lower end and two flashboards by spiral-lock between two flashboards, center push rod can drive two flashboards by its lower end and move along the sealing surface on the described valve body is parallel up and down, described stage clip is pressed on the sealing surface that valve stops two flashboards outsides sealing surface all the time, and the below that pod apertures is positioned at flashboard is used for the impurity of drain.
Be provided with some stage clips in the above-mentioned patent document between two flashboards, guarantee that flashboard outside sealing surface is pressed on the sealing surface of valve body all the time, but because stage clip is to be in by pressure condition all the time, when gate valve is opened, the underpart of flashboard may be got out certain distance toward two outsides by stage clip, when closing a floodgate once more, can have deviation between two sealing surfaces, thereby influence the work of gate valve, this gate valve job insecurity.
Summary of the invention
The purpose of this utility model is, the plate valve of a kind of working stability, band pod apertures that structural integrity is strong is provided.
The utility model is achieved by the following scheme: a kind of plate valve with pod apertures, comprise valve body, valve gap, valve gap is provided with operation screw rod and operation handwheel, be provided with and operate the guillotine mechanism of screw rod interlock in the valve body, guillotine mechanism comprises two flashboard and center push rod of separating mutually, two flashboards are oppositely arranged, the position that is positioned at the flashboard below on the valve body is provided with pod apertures, it is characterized in that center push rod be two-sided wedge-shaped blocks and with the operation screw rod be connected, two flashboards are fixed by bolts to respectively on the piece that rises, rise to have on the piece spacing sliding chamber axially is set, the sphenoid surface of two-sided wedge-shaped blocks is provided with slide block relative with position, spacing sliding chamber and that cooperate with spacing sliding chamber slippage, two pieces that rise are arranged on the both sides of two-sided wedge-shaped blocks, and sphenoid surface constitutes the switching structure of gate valve mechanism relatively.
This is provided with and utilizes rise piece and two-sided wedge-shaped blocks to constitute a switching structure, the flashboard and the piece bolt that rises, therefore flashboard can not produce the visibility point variation, compare stability with the flashboard in the documents better, and spacing sliding chamber and slide block are necessary, and both cooperate the lifting gear that constitutes flashboard, because the cooperation between the sphenoid surface, can effectively push flashboard, have very strong integrity, sealing is fine.
Of the present utility modelly further be set to: described spacing sliding chamber is a spacing sliding chamber of rectangular that axially is provided with, and slide block is the rectangular slide block.
In the utility model, slide block and spacing sliding chamber can take different shapes, as circle, arc, linear, slide block and spacing sliding chamber are all adopted rectangular, and this is best mode, because rectangular slide block cooperates with sliding chamber, guidance quality is better, and very stable after the combination, horizontal slip can not appear, and very stable in the time of work.
Of the present utility modelly further be set to: described slide block center is provided with manhole, and flashboard side inner panel face is provided with the cylinder adaptive with manhole, and cylinder passes spacing sliding chamber and stretches into manhole.
This is arranged on and also is provided with cylinder on the flashboard, and adaptive with the manhole on the two-sided wedge-shaped blocks, and combination back integrity is stronger like this, more stable work.
Rise piece and two-sided wedge-shaped blocks of said structure utilization constitutes a switching structure, flashboard and wedge-shaped blocks bolt, therefore flashboard can not produce the visibility point variation, compare stability with the flashboard in the documents better, and spacing sliding chamber and slide block are necessary, and both cooperate the lifting gear that constitutes flashboard, because the cooperation between the sphenoid surface, can effectively push flashboard, have very strong integrity, sealing is fine.
