Abstract
The utility model discloses a filter butterfly valve, which comprises the following components: a valve body, the inside one end of valve body is equipped with valve plate, valve plate and the seamless contact of valve body inner wall, the through -hole has been seted up to the valve plate intermediate position, and the valve rod passes through -hole, valve rod bottom rotate with the valve body to be connected, and the valve body is stretched out on the valve rod top, and the valve rod is perpendicular with the valve body, the filter screen is installed to valve body right -hand member downside, and the port department of filter screen installs the apron. The utility model discloses combine filter and butterfly valve and make up into a filter butterfly valve, saved the mounted position of the blue butterfly valve of traditional method, simple structure, reasonable in design, it is small, light in weight, simple to operate, save material and installation cost, but quick open -lose, easy operation, the differential pressure of production is very little, has good fluid control characteristic, have filtering capability, can clear away the impurity in the medium to the normal use of protection valve and equipment, extensively being applicable to industry such as oil, coal gas, chemical industry, water treatment, still being applicable to the cooling water system of heat power station, the suitability is strong.
Description
Technical field
This utility model relates to a kind of valve, specifically a kind of filtration butterfly valve.
Background technology
In traditional Pipe installing, in order to reduce installation cost, there is considerable engineering that filter is all only installed in main pipeline, and branch pipe(tube) does not plan to install filter, and often it is contemplated to save cost, neglect and branch pipe(tube) has had significant component of residual foreign material (particularly newly installed pipeline, as: welding slag, steel wire foreign material, blinding, broken medicated clothing etc.).Without installing filter, butterfly valve seal will be damaged by these foreign material, makes the butterfly valve plate can not be fully airtight and cause that butterfly valve leaks, or destroys the valve plate of butterfly valve.There is blocking and stuck situation in the valve plate of butterfly valve, the valve plate of butterfly valve is blocked and can be caused that YE produces stall, finally burns out the motor of YE and produces unnecessary loss.
Utility model content
The purpose of this utility model is in that providing a kind of filters butterfly valve, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of filtration butterfly valve, including valve body, described valve inner one end is provided with valve plate, and valve plate is seamless with valve interior wall to be contacted；Valve plate centre position offers through hole, and valve rod is through described through hole, and valve rod bottom and valve body are rotationally connected, and valve stem tip stretches out valve body, and valve rod is vertical with valve body；Being provided with drainage screen on the downside of valve body right-hand member, the port of drainage screen is provided with cover plate.
As further program of the utility model: the radian of described valve plate sidewall is identical with the radian of valve interior wall.
Compared with prior art, the beneficial effects of the utility model are: filter is combined with butterfly valve and is combined into a filtration butterfly valve by this utility model, saves the installation site of conventional flange butterfly valve, simple in construction, reasonable in design, volume is little, lightweight, easy for installation, save material and installation cost, can fast opening and closing, simple to operate, the Pressure Drop produced is only small, has good fluid handling properties；There is filtering function, it is possible to remove the impurity in medium, to protect the normal use of valve and equipment；Being widely used in the industry such as oil, coal gas, chemical industry, water process, apply also for the cooling water system of thermo-power station, the suitability is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-valve body, 2-valve rod, 3-valve plate, 4-drainage screen, 5-cover plate.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, a kind of filtration butterfly valve, including valve body 1, the internal one end of described valve body 1 is provided with valve plate 3, and valve plate 3 contacts with wall seamless in valve body 1, does not have blocking and stuck situation, it is to avoid the situation of burn-down of electric motor occurs；Valve plate 3 centre position offers through hole, and valve rod 2 is through described through hole, and valve rod 2 bottom and valve body 1 are rotationally connected, and valve body 1 is stretched out on valve rod 2 top, and valve rod 2 is vertical with valve body 1；Being provided with drainage screen 4 on the downside of valve body 1 right-hand member, the port of drainage screen 4 is provided with cover plate 5, and drainage screen 4 can remove the impurity in medium.
Further, the radian of valve plate 3 sidewall described in the utility model is identical with the radian of valve body 1 inwall.
This utility model has only to one installation procedure, simple installation, saves the set-up time；A pair flange plate and some screws is saved than existing mounting means.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model.Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but not each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should be made as a whole by those skilled in the art, and the technical scheme in each embodiment through appropriately combined, can also form other embodiments that it will be appreciated by those skilled in the art that.
