Abstract
The utility model provides a fission blind plate valve belonging to the metallurgy valve technical field, and is used for solving the shutdown problem of a pipe network system caused by replacement of corrugated pipes. The utility model consists of a left valve body, a right valve body, a middle valve plate, a corrugated pipe, a flexible adjusting guide screw and a base; a corrugated pipe valve body is added in the improved utility model; the corrugated pipe is arranged on the corrugated pipe valve body which is butted with the left valve body or the right valve body. The utility model is provided with the corrugated pipe on the added corrugated pipe valve body, facilitates the replacement of damaged corrugated pipe by the separation of the corrugated pipe from the left valve body or the right valve body on the precondition that a transmission system of the blind plate valve is not changed, solves the shutdown problem of the pipe network system caused by the replacement of the corrugated pipe, reduces the effects of the damage of the corrugate pipe on the production to the minimum, saves time for replacement, reduces the cost of spares, and is suitable for installation and application as blind plate valves in transmission pipelines such as coal gas, etc.
Description
Technical field
The utility model relates to gas pipe line with blind plate (plate) valve, belongs to metallurgical valve technology field.
Background technique
On the various gas pipe lines of metallurgy industry, cut off coal gas, all be provided with the blank-plate valve of corresponding specification in order to wait where necessary.Consult Fig. 2.Left and right valve body 1,2 is arranged in the blank-plate valve, turnover valve plate 3, have bellows 4 on a left side or the right valve barrel, bellows can be by telescopic adjustment leading screw 5 control collapsing lengths, so that the valve plate space between the valve body can open or dwindle, thereby satisfy the switching upset of valve plate blind plate end, glasses end and switch the usage requirement that the back contacts with left and right valve seal.Though bellows is a stainless steel, because its tube wall is thinner, in the use, particularly under gas composition complexity and changeable situation, tube wall still can be subjected to very big corrosion, can gas leakage occur because of corrosion.In the above-mentioned blank-plate valve, because bellows 4 directly is placed on a left side or the right valve barrel, need interrupts coal gas during replacing and carry, the normal normal coal gas of pipe network system that therefore interrupts is carried, and causes large size to stop production, and forms massive losses.How to reduce bellows and damage the influence to producing when changing, be the difficult problem of industry always.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of split blank-plate valve, solve to change the problem that bellows causes pipe network system to be cut out causing stopping production.
The alleged problem of the utility model realizes with following technological scheme:
A kind of split blank-plate valve is provided with left and right valve body 1,2, middle valve plate 3 in the formation, bellows 4, telescopic adjustment leading screw 5 and base 6 are improved to, and set up bellows valve body 7 in the formation, described bellows 4 is placed on the bellows valve body 7, and the bellows valve body docks with a left side or right valve barrel.
Above-mentioned split blank-plate valve, described bellows valve body 7 docks with right valve barrel 2, and right valve barrel 2 is the outlet end of valve.
Above-mentioned split blank-plate valve, described bellows valve body 7 docks with right valve barrel 2, and right valve barrel 2 is the entrance point of valve.
The utility model is placed in bellows on the bellows valve body of setting up, under the prerequisite that does not change the transmission system of blank-plate valve own, by separating of bellows and a left side or right valve barrel, made things convenient for the replacing after bellows damages, solved the problem that bellows causes pipe network system to be cut out of changing, the influence that bellows damages producing can be reduced to minimum, saving is changed consuming time, reduce the spare part cost, suit to install and use as the blank-plate valve in the delivery lines such as coal gas.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation;
Fig. 2 is the utility model embodiment 2 structural representations;
Fig. 3 is existing blank-plate valve structural representation.
The component label is respectively in the accompanying drawing: 1-left valve barrel, 2-right valve barrel, 3-valve plate, 4-bellows, 5-telescopic adjustment leading screw, 6-base, 7-bellows valve body, 8-support, 9-screw plate, the wear-resisting water conservancy diversion cover of 10-, 11-seal ring.
Embodiment
Consult Fig. 3.In the diagram blank-plate valve, left valve barrel 1 is affixed with base 6, and the support 8 of right valve barrel 2 is passed through the pulley slippage on base 6.Valve plate 3 lower ends are that blind plate end, upper end are the glasses nose end.Telescopic adjustment leading screw 5 is arranged in the screw plate 9 on the left and right valve body, and bellows 4 is positioned on the right valve barrel 2.Rotary extension is regulated leading screw 5 can make bellows 4 outwards stretch or inwardly contraction, when bellows 4 shrank, magnified in the valve plate space between the left and right valve body, the position of valve plate 3 rotatable switching blind plate ends, glasses end, when bellows 4 stretches, valve plate 3 and the tight contact seal of left and right valve body.Close pipe network system when changing bellows.Wear-resisting water conservancy diversion cover 10 among the figure is used to intercept the coal gas medium and reduces abrasion of corrugated pipe with contacting of bellows.Seal ring 11 is arranged on the valve plate 3.
Consult Fig. 1,2.The utility model is no longer settled bellows 4 on left valve barrel 1 or the right valve barrel 2 after improving, and bellows 4 is placed on the bellows valve body of setting up 5.Bellows valve body 5 is isometrical with a left side or right valve barrel, and the one end docks with a left side or right valve barrel by the flange plate of coupling, the flange of the other end and place pipe network coupling.When changing bellows 4, only need the blind plate end-grain cutting of valve plate 3 is changed between the left and right valve body, make blank-plate valve in the closed position, by telescopic adjustment leading screw 5 left and right valve body is closely contacted with the blind plate end and cut end coal gas, and the cloth bag case that will link to each other with bellows valve body 5 cut-out, just detachably change the bellows 4 on the bellows valve body 7.
Still consult Fig. 1,2.Bellows valve body 5 is to dock with left valve barrel 1 or dock with right valve barrel 2, and the medium inlet/outlet was decided the influence degree of producing when the ablepsia plate valve used.Less to the production influence degree when the stopping production of media outlet direction, this moment, bellows valve body 5 a surnames were docked with the outlet end valve body of valve, and embodiment 1 as shown in Figure 2; Less to the production influence degree to stopping production as the medium importer, bellows valve body 5 suits to dock with the entrance point valve body, both has been arranged on the medium entrance point valve body embodiment 2 as shown in Figure 2.
