Abstract
The utility model relates to a kind of anti-coking gate valve, it comprises valve body, valve seat, valve gap, flashboard, valve rod and drive unit, in valve body, valve seat is set, valve rod is flexibly connected by movable sheath with flashboard, valve body upper end is fixedly connected with valve gap, valve rod upper end is fixedly connected with drive unit, valve seat and rams contact place arrange sealing strip, described flashboard lower end has groove, groove upper end has at least one aperture, described aperture is communicated with groove, described aperture when flashboard cuts out higher than the position of valve seat lower end sealing strip, a groove is opened in the bottom of flashboard, ensure that medium flows smoothly, groove offers aperture, and the height of aperture will ensure when valve closing, the top of aperture will on valve base sealing band, because consider the wearing and tearing stroke of flashboard, be exactly like this want medium flowing in the duct slowly, carry out transferring heat, and can not coking, do not need heat supply to prevent medium coking, so just can reduce the consumption of the energy.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of anti-coking gate valve.
Background technique
In petroleum refining industry, along with the development of crude oil deep process technology, most oil refinery adopts coking Cemented filling high temperature sludge wet goods high viscosity medium.
And coking pipeline is in order to prevent coking, its general way is that the whole pipeline mode of mixing heat pipe is ensured that medium can not coking, if doing so be cumbersome, because so also will this pipeline heat supply be given, once heat supply pipeline goes wrong, whole coking pipeline will coking, and that just loses large.
Model utility content
For the shortcoming and defect that prior art exists, the utility model provides a kind of anti-coking gate valve.
The technological scheme that the utility model adopts is: a kind of anti-coking gate valve, it comprises valve body, valve seat, valve gap, flashboard, valve rod and drive unit, in valve body, valve seat is set, valve rod is flexibly connected by movable sheath with flashboard, valve body upper end is fixedly connected with valve gap, valve rod upper end is fixedly connected with drive unit, described valve seat and rams contact place arrange sealing strip, described flashboard lower end has groove, described groove upper end has at least one aperture, described aperture is communicated with groove, described aperture when flashboard cuts out higher than the position of valve seat lower end sealing strip.
Described groove is horn-like, and described groove is osculum near material feeding mouth, and described groove is large mouth near discharge port.
Described aperture when flashboard cuts out higher than valve seat lower end sealing strip 2-3mm.
Described valve seat comprises left valve seat and right valve seat, and both relatively form V-type and place.
Described flashboard is wedge shape, and suitable with valve seat.
The height of described osculum and the sealing strip height of valve seat suitable, the height of described large mouth is greater than the height of valve base sealing band.
Described drive unit is handwheel.
The beneficial effects of the utility model are: a groove is opened in the bottom of flashboard, ensure that medium flows smoothly, groove offers aperture, and the height of aperture will ensure when valve closing, the top of aperture will on valve base sealing band, because consider the wearing and tearing stroke of flashboard, (amount of flow is little like this to want medium flowing in the duct slowly, disregard consideration), carry out transferring heat, and can not coking, heat supply just can not be needed to prevent medium coking, so just can reduce the consumption of the energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan view of flashboard.
Fig. 3 is the bottom schematic view of flashboard.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As Fig. 1, shown in Fig. 2 and Fig. 3, the utility model provides a kind of anti-coking gate valve, it comprises valve body 1, valve seat 2, valve gap 7, flashboard 3, valve rod 4 and handwheel 5, valve seat 2 is set in valve body 1, valve rod 4 is flexibly connected by movable sheath 6 with flashboard 3, valve body 1 upper end is fixedly connected with valve gap 7, valve rod 4 upper end is fixedly connected with handwheel 5, described valve seat 2 arranges sealing strip 8 with flashboard 3 contacting point, described flashboard 3 lower end has horn-like groove, described groove is osculum 32 near material feeding mouth, described groove is large mouth 31 near discharge port, described osculum 32 upper end has at least one aperture 33, described aperture 33 is communicated with groove, described aperture 33 when flashboard 3 cuts out higher than the position of valve seat 2 lower end sealing strip 8.
Described aperture 33 when flashboard cuts out higher than valve seat 2 lower end sealing strip 2-3mm.
Described valve seat 2 comprises left valve seat and right valve seat, and both relatively form V-type and place, and described flashboard 3 is wedge shape, and suitable with valve seat 2.The design of V-shaped valve seat 2 and wedge shape flashboard 3, ensure that the passage of flashboard 3 bottom is shorter, the time flow through is shorter, shortens the time of contact of medium and flashboard.
A horn-like groove is opened exactly in the bottom of flashboard 3, in figure, arrow direction indication is that MEDIA FLOW is to direction, medium enters from osculum 32, go out from large mouth 31, the degree of finish of this horn-like groove is very high, so just can ensure that medium flows smoothly, and the height of aperture 33 will ensure when valve closing, the bottom of aperture 33 will on valve base sealing band taller 2 ~ 3mm, because consider the wearing and tearing stroke of flashboard, medium flowing in the duct is slowly wanted in such design, and (amount of flow is little, disregard consideration), carry out transferring heat, and can not coking, heat supply just can not be needed to prevent medium coking, the consumption of the energy can be reduced.
The height of described osculum 32 and the sealing strip height of valve seat 2 suitable, the height of described large mouth 31 is greater than the height of valve base sealing band.When flashboard 3 cuts out time, osculum 32 can be sealed by sealing strip 8, then some is not given sealing by sealing strip to large mouth 31, the pipeline formed by unencapsulated large mouth 31 and aperture 33 carries out the circulation of medium, and only circulate by the aperture 31 of osculum 32 upper end in material feeding mouth place, and aperture 33 can carry out aperture design as required, and can design multiple aperture, improve flow speed, realize good anti-coking effect.
Embodiment should not be considered as restriction of the present utility model, but any improvement done based on spirit of the present utility model, all should within protection domain of the present utility model.
