Description
Technical field
The utility model belongs to valve class, relates to gate valve, especially automatically cleaning gate valve.
Background technique
Along with the development of industrial technology, in industrial pipeline or chemical industry equipment, the medium of fluid becomes increasingly complex, the particle mostly containing easy precipitation in medium, or the material of easily coking crystallization, along with temperature change or flow through the change of area, be just easy to deposition or coking.Valve particularly gate valve, as the main device controlling fluid, easily occurs especially.And once occur, then valve seal effect can be caused to reduce, impact uses, and consequence is serious, and valve will be caused to scrap, and even has an accident because of valve invalidation.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of structure is simple, the valve that can clean or eliminate the effects of the act uses valve inner deposition and coking, working life factory, automatically cleaning gate valve that using scope is large.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of automatically cleaning gate valve, comprise valve body, valve gap, valve rod and closure member, valve body upper center coaxially installs valve gap, coaxially valve rod is coated with in the middle part of described valve gap, this valve rod lower end to be stretched in valve body and is coaxially fixed with closure member in valve rod lower end, valve rod upper end above valve gap is provided with drive unit, and this drive unit rotarily drives valve rod ascending, descending, it is characterized in that: be provided with a tail end cleaning apparatus for self by welding or being threaded in the middle part of valve body lower end.
And both sides, described valve gap upper end are provided with a upper end cleaning apparatus for self respectively by welding or being threaded.
And described two upper end cleaning apparatus for self are symmetricly set on valve rod both sides and upper end cleaning apparatus for self and valve rod axis angle at 45 °.
And, described tail end cleaning apparatus for self and upper end cleaning apparatus for self are equipped with control valve.
And described closure member is connected by T-slot with valve rod lower end.
Advantage of the present utility model and good effect are:
1, the valve body afterbody of this automatically cleaning gate valve is provided with cleaning apparatus for self by the mode of welding or be threaded, water, air or steam is injected to gate valve inside by cleaning apparatus for self, the deposition in the middle of valve body bottom groove, coking or crystallization can be removed, eliminate because of body base deposition, coking or crystallization, make valve closing not in place and the valve seal leakage problem of generation.
2, this automatically cleaning gate valve, by the mode of welding or be threaded, two cleaning apparatus for self are installed on valve gap top, cleaning apparatus for self and valve rod axis angle at 45 °, inject water, air or steam by cleaning apparatus for self to gate valve inside, the coking on valve rod and closure member or crystallization can be removed.Eliminate closure member to place for a long time on top, main passage, medium turbulent flow and the coking that causes of temperature reduction or crystallization, eliminate the valve caused because of closure member coking crystallization and cannot to close or be not closed completely phenomenon.Also can eliminate the coking on valve rod, avoid damaging stem packing part, ensure that sealing is reliable.
3, on cleaning apparatus for self, be provided with control valve, pressure and the flow of water, air or the steam injected can be regulated according to the needs of operating mode, meet the requirement of operating mode.
4, this automatically cleaning valve, can import and export arbitrary position at valve body as required increases mounted and self purging device, to eliminate the issuable deposition of import and export, coking or crystallization.
5, simple, the design science of the utility model structure, simple to operate, has self-cleaning effect, long service life, can be widely used in various easy coking, crystallization or deposition occasion.
Accompanying drawing explanation
Fig. 1 is the utility model structural front view;
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of automatically cleaning gate valve, comprise valve body 7, valve gap 3, valve rod 5 and closure member 6, valve body upper center coaxially installs valve gap, coaxially valve rod is coated with in the middle part of described valve gap, this valve rod lower end to be stretched in valve body and is coaxially fixed with closure member in valve rod lower end, valve rod upper end above valve gap is provided with drive unit 1, and this drive unit rotarily drives valve rod ascending, descending.In the present embodiment, closure member is connected by T-slot with valve rod lower end.
Innovative point of the present utility model is:
By welding or being threaded, a tail end cleaning apparatus for self 8 is installed in the middle part of valve body lower end, injects water, air or steam by cleaning apparatus for self to gate valve inside, the deposition in the middle of valve body bottom groove, coking or crystallization can be removed.Eliminate because of body base deposition, coking or crystallization, make valve closing not in place and the valve seal leakage problem of generation.
Both sides, valve gap upper end are provided with a upper end cleaning apparatus for self 4 respectively by welding or being threaded, these two upper end cleaning apparatus for self are symmetricly set on valve rod both sides and upper end cleaning apparatus for self and valve rod axis angle at 45 °, inject water, air or steam by these two upper end cleaning apparatus for self to gate valve inside, the coking on valve rod and closure member or crystallization can be removed.Eliminate closure member to place for a long time on top, main passage, medium turbulent flow and the coking that causes of temperature reduction or crystallization, eliminate the valve caused because of closure member coking crystallization and cannot to close or be not closed completely phenomenon.Also can eliminate the coking on valve rod, avoid damaging stem packing part, ensure that sealing is reliable.
Tail end cleaning apparatus for self and upper end cleaning apparatus for self are equipped with control valve, can according to the pressure of the water, air or the steam that need regulable control valve regulation to inject of operating mode and flow.
This automatically cleaning valve, can import and export arbitrary position at valve body as required increases mounted and self purging device, to eliminate the issuable deposition of import and export, coking or crystallization.
