The utility model solves its technical problem and takes following technological scheme to realize:
A kind of two-way flange connecting central plate high pressure sealing butterfly valve, comprise valve body, valve rod, valve seat, dish plate and handle, outer, the rear and front end coaxial-symmetrical of valve body is shaped with flanged plate, and on flanged plate, radial equipartition is shaped with multiple mounting hole, for being connected with piping flange; In the middle part of valve body, be longitudinally provided with a valve rod, this valve rod upper end is stretched out valve body and is coaxially installed with one handle; Valve seat is axially installed with in valve body, on valve rod in valve seat, radial direction is provided with dish plate, it is characterized in that: dish plate is double-sided symmetrical structure, valve rod center in valve body is fixedly mounted with valve plate by set screw, above valve plate above set screw, interval is provided with two locating studs, and these two locating studs all embed and are fixed in valve rod;
Described valve seat is the one-body molded cylinder barrel shaped structure made of rubber, and in the middle part of this valve seat, radial direction is coaxially shaped with the orthohexagonal valve rod mounting hole coordinated with valve rod; 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; In the middle part of valve seat wall coaxial be shaped with one in the middle part of bulge loop;
Dish plate outer rim is hemisphere face through polishing treatment, and in the middle part of the sealing surface sealing the valve seat contacted with dish plate, radial direction is shaped with arc sealed groove, the hemisphere face edge of the coated dish plate of sealing groove.
And described valve rod is positive six prism structures, valve rod is coaxially inlaid in regular hexagon valve rod mounting hole made in the middle part of dish plate.
Advantage of the present utility model and good effect are:
1, the support performance of the rubber gasket of this butterfly valve is good, and firmly stable, simple and compact for structure, adjusting function is good, ensures to support moment not yielding again.
2, the machining accuracy of this butterfly valve is high, and valve seat is not yielding, and the deformation effects such as tolerance is little, the expansion upheaval of valve seat are little, the long service life of valve seat.
3, the dish plate boundary dimension of this butterfly valve is accurate, and good airproof performance after throttling, without interference phenomenon between dish plate and valve seat, thus ensures that operational torque is little, valve long service life.
4, the utility model structural strength is high, good seal performance, dish plate and valve seat quality of fit high, torque resistance is little, and compressive resistance performance is good, and the installation of valve part is simple, long service life.
Accompanying drawing explanation
Fig. 1 be of the present utility model in cut open structural front view;
Fig. 2 cuts open right elevation in Fig. 1;
Fig. 3 is valve seat construction schematic diagram in the utility model;
Fig. 4 is that the A-A of Fig. 3 is to sectional 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 two-way flange connecting central plate high pressure sealing butterfly valve, comprise valve body 3, valve rod 2, valve seat 4, dish plate 5 and handle 1, as shown in accompanying drawing 1 to accompanying drawing 2, outer, the rear and front end coaxial-symmetrical of valve body is shaped with flanged plate, and radial equipartition is shaped with multiple mounting hole on flanged plate, for being connected with piping flange; In the middle part of valve body, be longitudinally provided with a valve rod, 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, on the valve rod in valve seat, radial direction is provided with dish plate.
Innovative point of the present utility model is:
Described valve rod is positive six prism structures, valve rod is coaxially inlaid in regular hexagon valve rod mounting hole made in the middle part of dish plate, and dish plate is double-sided symmetrical structure, and valve rod center in valve body is fixedly mounted with valve plate by set screw 6, the rotation under the twisting force of valve rod of dish plate, thus the keying of control valve;
In order to strengthen the installation stability of valve plate, above the valve plate above set screw, interval is provided with two locating studs, and these two locating studs all embed and are fixed in valve rod.
Described valve seat is the one-body molded cylinder barrel shaped structure made of rubber, and in the middle part of this valve seat, radial direction is coaxially shaped with the orthohexagonal valve rod mounting hole coordinated with valve rod; The axial two ends outer rim of valve seat is all shaped with edge bulge loop 9, and this edge bulge loop is inlaid in the made valve seat mounting groove in the axial two ends of valve body.
