Abstract
nullThe present invention relates to a kind of anti-coking gate valve，It includes valve body、Valve seat、Valve gap、Flashboard、Valve rod and driving means，Valve seat is set in valve body，Valve rod is flexibly connected by movable sleeve with flashboard，Valve body upper end is fixing connects valve gap，Valve rod upper end is fixing connects driving means，At valve seat and rams contact, band is set，Described flashboard lower end has groove，Groove upper end has at least one aperture，Described aperture connects with groove，Described aperture is higher than the position of valve seat lower end band when flashboard cuts out，A groove is opened in the bottom of flashboard，Ensure that medium flows smoothly，Aperture is offered on groove，And the height of aperture to ensure when valve closing，The top of aperture will be on valve base sealing band，Because it is contemplated that the abrasion stroke of flashboard，Like this seek to medium flowing in the duct slowly，Transmit heat，Without coking，Need not heat supply to prevent medium coking，Thus can reduce the consumption of the energy.
Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of anti-coking gate valve.
Background technology
In petroleum refining industry, along with crude oil deep process technology develops, most oil plant uses the coking pipeline conveying contour viscous media of high temperature residual oil.
And coking pipeline is in order to prevent coking, its general way is that the whole pipeline mode mixing heat pipe is ensured that medium will not coking, if doing so it is cumbersome, because the most also to give this pipeline heat supply, once heat supply pipeline goes wrong, whole coking pipeline will coking, that just loses big.
Summary of the invention
The shortcoming and defect existed for prior art, the invention provides a kind of anti-coking gate valve.
The technical solution adopted in the present invention is: a kind of anti-coking gate valve, it includes valve body, valve seat, valve gap, flashboard, valve rod and driving means, valve seat is set in valve body, valve rod is flexibly connected by movable sleeve with flashboard, valve body upper end is fixing connects valve gap, valve rod upper end is fixing connects driving means, at described valve seat and rams contact, band is set, described flashboard lower end has groove, described groove upper end has at least one aperture, described aperture connects with groove, and described aperture is higher than the position of valve seat lower end band when flashboard cuts out.
Described groove is horn-like, and described groove is osculum near charging aperture, and described groove is big mouth near discharging opening.
Described aperture is higher than valve seat lower end band 2-3mm when flashboard cuts out.
Described valve seat includes 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 is suitable with the band height of valve seat, and the height of described big mouth is more than the height of valve base sealing band.
Described driving means is handwheel.
The invention has the beneficial effects as follows: a groove is opened in the bottom of flashboard, ensure that medium flows smoothly, aperture is offered on groove, and the height of aperture to ensure when valve closing, the top of aperture will be on valve base sealing band, because it is contemplated that the abrasion stroke of flashboard, (amount of flow is little like this to seek to medium flowing in the duct slowly, disregard consideration), transmit heat, without coking, it is possible to need not heat supply to prevent medium coking, thus can reduce the consumption of the energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the front view of flashboard.
Fig. 3 is the bottom schematic view of flashboard.
Detailed description of the invention
Embodiments of the present invention is further illustrated below in conjunction with the accompanying drawings:
Such as Fig. 1, shown in Fig. 2 and Fig. 3, the present invention provides a kind of anti-coking gate valve, it includes 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 sleeve 6 with flashboard 3, valve body 1 upper end is fixing connects valve gap 7, valve rod 4 upper end is fixing connects handwheel 5, described valve seat 2 arranges band 8 with flashboard 3 contact position, described flashboard 3 lower end has horn-like groove, described groove is osculum 32 near charging aperture, described groove is big mouth 31 near discharging opening, described osculum 32 upper end has at least one aperture 33, described aperture 33 connects with groove, described aperture 33 is higher than the position of valve seat 2 lower end band 8 when flashboard 3 cuts out.
Described aperture 33 is higher than valve seat 2 lower end band 2-3mm when flashboard cuts out.
Described valve seat 2 includes 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.V-shaped valve seat 2 and the design of wedge shape flashboard 3, it is ensured that the passage of flashboard 3 bottom is shorter, and the time flow through is shorter, shortens the time of contact of medium and flashboard.
It is exactly to open a horn-like groove in the bottom of flashboard 3, in figure, arrow direction indication is that medium flows to direction, medium enters from osculum 32, go out from big mouth 31, the fineness of this horn-like groove is the highest, the most just can ensure that medium flows smoothly, and the height of aperture 33 to ensure when valve closing, the bottom of aperture 33 will on valve base sealing band taller 2 ~ 3mm, because it is contemplated that the abrasion stroke of flashboard, such design seeks to medium flowing in the duct slowly, and (amount of flow is little, disregard consideration), transmit heat, without coking, just can need not heat supply to prevent medium coking, the consumption of the energy can be reduced.
The height of described osculum 32 is suitable with the band height of valve seat 2, and the height of described big mouth 31 is more than the height of valve base sealing band.When flashboard 3 cuts out when, osculum 32 can be sealed by band 8, then some unsealed brings sealing to big mouth 31, pipeline by unencapsulated big mouth 31 and aperture 33 composition carries out the circulation of medium, and at charging aperture, only lean on the aperture 31 of osculum 32 upper end to circulate, and aperture 33 can carry out aperture design as required, and multiple aperture can also be designed, improve flow speed, it is achieved preferably anti-coking effect.
Embodiment is not construed as limitation of the present invention, but any spiritual improvements introduced based on the present invention, all should be within protection scope of the present invention.
