Abstract
The utility model relates to an all-rubber wafer butterfly valve, which consists of a valve body, a rubber valve seat, a butterfly plate and a valve rod, wherein the rubber valve seat is coaxially sealed and embedded in the valve body; the valve rod is radially arranged on the valve body; the butterfly plate is fixedly arranged on the valve rod in the rubber valve seat; right-angled upturned edges are arranged at the two ends of the rubber valve seat; and the valve body is embedded into a ring groove formed by the two upturned edges. According to the wafer butterfly valve, the right-angled upturned edges are arranged at the two ends of the cylindrical rubber valve seat to realize the positioning mounting of the valve seat and the valve body, so that the axial endplay of the valve seat in the valve body is avoided, and the service life of the butterfly valve is prolonged; and moreover, the butterfly valve is simple in overall structure, scientific and rational in design, convenient to mount, high in sealing performance and easy and labor-saving to open and close, and is a highly-creative new-generation wafer butterfly valve, and the cost is lowered twice to threefold.
Description
Technical field
The utility model belongs to the valve class, relates to butterfly valve, and especially a kind of full glue is to the folder butterfly valve.
Background technique
In the fluid-transporting tubing field, use comparatively extensive to the folder butterfly valve.Existing structure to the folder butterfly valve is to be made up of valve body, rubber valve seat, butterfly plate and valve rod; Co-axial seal setting-in rubber valve seat in the valve body; Valve rod radially is installed on the valve body, is installed butterfly plate on the valve rod in valve body, butterfly plate under the twisting force of valve rod rotation to open and close the formed runner of rubber valve seat; The mode mounting flange sheet that adds sealing gasket is adopted in the coaxial both sides, front and back of valve body, and flange plate is connected with fluid line is coaxial.
Said structure is that traditional shortcoming that folder butterfly valve form is existed is:
1, owing to need co-axial seal setting-in rubber valve seat in the valve body, because rubber valve seat need keep certain thickness, so valve body does greatlyyer, and weight is heavier.
2, rubber valve seat is sealing and coaxial being inlaid in the valve body, is bearing axial active force, and under the rotation friction of butterfly plate, is being easy to generate axial float, and not only the life-span lacks, and sealability is affected.
3, at coaxial both sides, the front and back mounting flange sheet of valve body, because rubber valve seat can't be realized end face seal preferably, therefore need between flange plate and valve body, sealing gasket be installed, technology is comparatively loaded down with trivial details.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, provide a kind of design science, rational in infrastructure, overall tightness good and full glue with low cost to the folder butterfly valve.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of full glue is to the folder butterfly valve; Comprise that valve body, rubber valve seat, butterfly plate and valve rod constitute; Co-axial seal setting-in rubber valve seat in the valve body is radially installed valve rod on the valve body, install butterfly plate on the valve rod in rubber valve seat; It is characterized in that: said rubber valve seat is outer rim right angle, a two ends flanging formula structure, two the formed annular groove setting-in of flange valve bodies.
And two flange inner edges of said rubber valve seat are processed the form that coats valve body.
The advantage and the good effect of the utility model are:
1, this processes outer rim right angle, two ends flanging formula structure to the folder butterfly valve with columnar rubber valve seat; Two the formed annular groove setting-in of flange valve bodies; Realize the location and installation of valve seat and valve body thus; Avoid the axial float of valve seat in valve body, improved the sealability of butterfly plate and valve seat, prolonged the working life of butterfly valve.
2, this rubber valve seat to the folder butterfly valve can location and installation on valve body; Can effectively reduce the diameter of valve body thus; The corresponding attenuate of the thickness of rubber valve seat has not only reduced cost of material, and also having improved rubber valve seat is the hardness of skeleton with the valve body; Alleviate the active force that butterfly plate opens and closes, correspondingly improved the sealing of butterfly plate.
3, this to the made flange of rubber valve seat of folder butterfly valve can the replacement seal flange plate sealing gasket, therefore simplified technology.
4, the utility model overall structure is simple, and design science is reasonable, simple installation, and sealing is strong, opens and closes easily laborsavingly, has reduced 2-3 cost doubly, is that the higher a new generation of novelty is to the folder butterfly valve.
Description of drawings
Fig. 1 is the structural front view of the utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is that the A-A of Fig. 1 is to cross-sectional view.
Embodiment
Below in conjunction with accompanying drawing and through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of full glue comprises that to the folder butterfly valve valve body 2, rubber valve seat 3, butterfly plate 4 and valve rod 1 constitute, and on valve body, is shaped on valve body stiffening rib 5, and co-axial seal setting-in rubber valve seat in the valve body is radially installed valve rod on the valve body, install butterfly plate on the valve rod in rubber valve seat.Butterfly plate is rotation in rubber valve seat under the twisting force of valve rod, to open and close the formed runner of rubber valve seat, has omitted the coaxial mounted flange plate in valve body both sides, front and back in the present embodiment accompanying drawing.
The innovative point of the utility model is:
Said rubber valve seat is outer rim right angle, a two ends flanging formula structure, and two the formed annular groove setting-in of flange valve bodies are realized the location and installation of valve seat and valve body thus.
In order to locate closely, two flange inner edges of rubber valve seat are processed the form that coats valve body, see Fig. 3.
Claims (2)
1. a full glue is to the folder butterfly valve; Comprise that valve body, rubber valve seat, butterfly plate and valve rod constitute; Co-axial seal setting-in rubber valve seat in the valve body is radially installed valve rod on the valve body, install butterfly plate on the valve rod in rubber valve seat; It is characterized in that: said rubber valve seat is outer rim right angle, a two ends flanging formula structure, two the formed annular groove setting-in of flange valve bodies.
2. full glue according to claim 1 is characterized in that the folder butterfly valve: two flange inner edges of said rubber valve seat are processed the form that coats valve body.
