Abstract

The utility model relates to a kind of anticorrosion heavy caliber light flat gate valve valve deck, including shell, floor is provided on the shell, the floor includes the first floor and the second floor, and the root of first floor is equipped with discharge outlet.The root of the first floor of the utility model is equipped with discharge outlet, the rainwater being detained in the hollow groove that first floor and the second floor are formed can move towards outflow along the second floor by discharge outlet, do not allow to be also easy to produce ponding at floor, to avoid valve deck by raindrop erosion yet.

Description

A kind of anticorrosion heavy caliber light flat gate valve valve deck

Technical field

The utility model relates to fluid control technology fields, and in particular to a kind of anticorrosion heavy caliber light flat gate valve valve Lid.

Background technique

In the piping engineering of chemical plant, due to the demands such as production and safety, pipeline need to install the valve of cutting logistics, cutting Valve is frequently with gate valve, and traditional gate valves internal structure is complicated, and manufacture material density is larger, and valve load is larger.To reduce piping The load of stress and support of pipelines, heavy caliber stop valve usually use light flat gate valve to replace conventional gate valve.It manufactures light-duty When flat gate valve, to mitigate valve weight, valve cap of valve generally uses thin-section casting, then the setting structure rib on thin-section casting Plate, to guarantee the overall structural strength of valve.

However, such heavy caliber light flat gate valve finds to have the following problems in actual use: in the perpendicular dress of valve Time is easy at the valve deck ponding at intersecting parallels floor, and rainwater often contains partial corrosion substance in chemical plant, permanent previous, can be right It causes to corrode at valve cap of valve, have an adverse effect to valve mechanism, serious person even generates the safety accident of valve leakage out of steam system.

Utility model content

It is asked to solve the technology that heavy caliber light flat gate valve valve deck is easy ponding at floor in perpendicular dress and is corroded Topic, the utility model provide a kind of anticorrosion heavy caliber light flat gate valve valve deck.The technical solution of the utility model is as follows:

A kind of anticorrosion heavy caliber light flat gate valve valve deck, including shell are provided with floor, the rib on the shell Plate includes the first floor and the second floor, and first floor and second floor are mutually perpendicular to and intersect, the first rib Plate is equipped with discharge outlet, and the discharge outlet is located at the junction of first floor and the shell.

Further, the height of the discharge outlet is 5mm.This highly less than the height of the first floor, both can guarantee ponding Discharge, moreover it is possible to guarantee the overall structural strength of floor on valve deck.

Further, the equal length of the width of the discharge outlet and first floor.That is it engraves the lower part of the first floor Sky will not surround dead angle with shell and the second floor, drain ponding, more efficiently prevent from shell and get rusty or be corroded.

Further, the shell is equipped with weathering, and the ratio of slope of the weathering is 0.03.Weathering is more conducive to The discharge of ponding.

Further, anti-corrosion paint layer is brushed on the shell.Anti-corrosion paint layer effectively prevent the corrosive goods in rainwater to verify The corrosion of valve cover surfaces.

Further, the material of the anti-corrosion paint layer is epoxy anticorrosive paint, polyurethane anti-corrosion paint or acrylic acid anti-decaying paint.This The favorable anti-corrosion effect of a little anti-decaying paints, the several years is also not easy to be corroded outdoors, effective protection valve deck.

The beneficial effects of the utility model are as follows: the utility model is equipped with draining in the junction of the first floor and shell Mouthful, the rainwater being detained in the hollow groove that the first floor is formed with the second floor can be flowed out by discharge outlet, at floor not It is easy to produce ponding, to also avoid valve deck by raindrop erosion.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it is also possible to obtain other drawings based on these drawings.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model 1-4, to the technical scheme in the embodiment of the utility model It is clearly and completely described, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than complete The embodiment in portion.

A kind of anticorrosion heavy caliber light flat gate valve valve deck, including shell 1 are provided with floor on the shell 1, described Floor includes the first floor 2 and the second floor 3, and first floor 2 and second floor 3 are mutually perpendicular to and intersect, described First floor 2 is equipped with discharge outlet 6, and the discharge outlet 6 is located at the junction of first floor 2 and the shell 1.It needs Bright, discharge outlet herein can make the replacement of same function, such as the rhone of palisading type.

Further, the height of the discharge outlet 6 is 5mm.This highly less than the height of the first floor 2, both can guarantee product Water discharge, moreover it is possible to guarantee the overall structural strength of floor on valve deck.

Further, the equal length of the width of the discharge outlet 6 and first floor 2.That is the lower part of the first floor 2 Hollow out will not surround dead angle with shell 1 and the second floor 3, drain ponding, more efficiently prevent from shell 1 and get rusty or be corroded.

Further, the shell 1 is equipped with weathering 7, and the ratio of slope of the weathering 7 is 0.03.Weathering 7 more added with Conducive to the discharge of ponding.

Further, anti-corrosion paint layer is brushed on the shell 1.Anti-corrosion paint layer effectively prevent the corrosive goods in rainwater to verify The corrosion of valve cover surfaces.

Working principle: for heavy caliber light flat gate valve valve deck in perpendicular dress, rainwater falls in the first floor 2 and the second floor 3 When in the hollow groove 5 of formation, it can be discharged by the discharge outlet 6 of the first floor 2 close to the root of shell 1, avoid ponding Generation.

The beneficial effects of the utility model are as follows: the utility model is equipped with draining in the junction of the first floor 2 and shell 1 Mouthfuls 6, the rainwater being detained in the hollow groove 5 that the first floor 2 is formed with the second floor 3 can be flowed out by discharge outlet 6, floor Place does not allow to be also easy to produce ponding, to avoid valve deck by raindrop erosion yet.

The above is preferred embodiments of the present invention, is not restricted to the utility model.To art technology For personnel, it is practical new also to should be regarded as this for the several improvements and modifications made without departing from the principle of this utility model The protection scope of type.
