Abstract
The utility model relates to a butterfly valve with a valve base lined with rubber. The butterfly valve comprises a valve body, a valve stem, the valve base, a butterfly plate and a handle, wherein the middle of the valve body is radially provided with the valve stem; the upper end of the valve stem is extended out of the valve body and is coaxially provided with the handle; the valve body is internally and axially provided with the valve base; the valve stem in the valve base is radially provided with the butterfly plate; the outer wall of the valve body is provided with multiple mounting plates at intervals; the valve stem is of a regular hexagonal prism structure; the valve plate is coaxially embedded in a regular-hexagonal valve stem mounting hole formed in the middle of the butterfly plate; a push-up bearing is coaxially arranged between the lower end of the valve stem and the valve base; the butterfly plate is of a bifacial symmetrical structure; the outer edge of the butterfly plate is polished to form a micro semi-spherical surface; the inner surface of the valve base is uniformly sprayed and coated with an elastic silica gel protective layer. The elastic silica gel protective layer is uniformly attached to the valve base of the butterfly valve, and rigid friction of the butterfly plate and the valve base is replaced by elastic contact, so that the valve base is not easy to damage, and the sealing performance of an elastic contact surface is better.
Description
Technical field
The utility model belongs to valve field, especially a kind of butterfly valve of valve seat line with rubber.
Background technique
Use at engineering pipeline transportation art valve is very extensive, the basic structure of valve is co-axial seal setting-in valve seat in valve body now, valve rod is radially installed on valve body, on valve rod in valve body, be fixedly mounted with dish plate, dish plate coordinates with valve base sealing, thereby dish plate rotation or movement under the driving of valve rod open and close the runner in valve seat.Valve body outer radial is shaped with a plurality of flange plates for being connected with pipeline, is shaped with bolt mounting holes on flange plate.The sealing of valve plate and durability are to weigh the major criterion of valve quality, and valve produces rigidity friction because dish plate is long-term with valve seat now, particularly dish panel edges and valve seat interference during the rotation of dish plate, and easily damage, causes seal failure, causes working life short.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of butterfly valve of valve seat line with rubber of reasonable in design, simple in structure, easy to operate, long service life is provided.
The utility model solves its technical problem and takes following technological scheme to realize:
A butterfly valve for valve seat line with rubber, comprises valve body, valve rod, valve seat, dish plate and handle, at valve body middle part, one valve rod is radially installed, and this valve rod upper end is stretched out valve body and is coaxially installed with one handle; In valve body, be axially installed with valve seat, dish plate is radially installed on the valve rod in valve seat, valve outer wall spaced radial is shaped with a plurality of mounting plates, it is characterized in that: described valve rod is positive six prism structures, valve plate is coaxially inlaid in the made regular hexagon valve rod mounting hole in dish plate middle part, and between valve rod lower end and valve seat, is coaxially installed with thrust bearing on; Described dish plate is double-sided symmetrical structure, and it is hemisphere face that dish plate outer rim adopts polishing treatment, and described valve seat interior surface evenly sprays flexible silicone protective layer.
And described valve seat is the one-body molded cylinder barrel shaped structure of making of rubber, the axial two ends outer rim of valve seat is all shaped with edge bulge loop, and this edge bulge loop is inlaid in the made valve seat mounting groove in the axial two ends of valve body.
And described valve seat middle part is coaxially shaped with a middle part bulge loop, inner radial wall projection and the dish plate fitted seal cut-off valve of this middle part bulge loop, the radial outside of middle part bulge loop is inlaid in the middle part annular groove that valve seat correspondence makes.
Advantage of the present utility model and good effect are:
1, the dish plate boundary dimension of this butterfly valve is accurate, and good airproof performance after throttling, between dish plate and valve seat without interference phenomenon, thereby guarantee that operational torque is little, valve long service life.
2, the valve seat of this butterfly valve is all with elastic silica gel protective layer, and the rigidity friction of dish plate and valve seat changes Elastic Contact into, not fragile, and the sealability of Elastic Contact face is better.
3, the utility model structural strength is high, good seal performance, and valve plate Corrosion Protection is good, can effectively meet corrosion resistant high requirement, and valve plate is high through polishing treatment and valve seat quality of fit, moment of torsion resistance is little, not fragile, and simple in structure, valve long service life.
Accompanying drawing explanation
Fig. 1 cuts open structural front view in of the present utility model;
Fig. 2 be Fig. 1 in cut open right elevation;
Fig. 3 is that the A-A of Fig. 2 is to cross section enlarged view.
Embodiment
Below in conjunction with accompanying drawing and 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 butterfly valve for valve seat line with rubber, comprises valve body 3, valve rod 2, valve seat 4, dish plate 5 and handle 1, at valve body middle part, one valve rod is radially installed, and this valve rod upper end is stretched out valve body and is coaxially installed with one handle; In valve body, be axially installed with valve seat, dish plate is radially installed on the valve rod in valve seat.
Valve outer wall spaced radial is shaped with a plurality of mounting plates 11, is all shaped with standard-sized mounting hole on the plurality of mounting plate, for being connected with piping flange.
Innovative point of the present utility model is:
Described valve rod is positive six prism structures, valve plate is coaxially inlaid in the made regular hexagon valve rod mounting hole in dish plate middle part, and between valve rod lower end and valve seat, be coaxially installed with thrust bearing 8 on, on this, thrust bearing effectively supports valve rod, prevent valve rod tenesmus, and increase valve rod rotate to flexibility reduce operational torque.
Described dish plate is double-sided symmetrical structure, and dish plate smooth surface is smooth, the rotation under the twisting force of valve rod of dish plate, thereby the keying of control valve.It is hemisphere face that dish plate outer rim adopts polishing treatment, reduces operational torque, and while guaranteeing sealing, dish plate and valve seat is sealed and matched.
Described valve seat interior surface evenly sprays flexible silicone protective layer 7, and this elastic silica gel protective layer spacer medium prevents from corroding valve seat, especially dish plate and valve seat position contact position,
