The utility model solves its technical problem and takes following technological scheme to realize:
The highi degree of accuracy butterfly valve that sealing surface is removable, comprise valve body, valve rod, valve seat, dish plate and handle, in the middle part of valve body, radial direction is provided with a valve rod, 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, on the valve rod in valve seat, radial direction is provided with dish plate, and valve outer wall spaced radial is shaped with multiple mounting plate, the plurality of mounting plate is all shaped with standard-sized mounting hole, it is characterized in that:
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;
Bulge loop in the middle part of being coaxially shaped with one in the middle part of valve seat, the radial outside of middle part bulge loop is shaped with annular mounting groove, is coaxially installed with a bracing ring between this annular mounting groove and valve body, and this bracing ring is inlaid in the corresponding middle part annular groove made of valve seat; Be shaped with a radial convex loop outside the middle part bulge loop of described valve seat, this radial convex loop is inlaid in the mounting groove that in the middle part of bracing ring, correspondence is made.
And described valve rod is positive six prism structures, valve plate 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 dish plate smooth surface is smooth, and dish plate outer rim adopts polishing treatment to be hemisphere face.
And the edge bulge loop at described two ends, middle part bulge loop and valve seat are integrally made.
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, ensure to support moment not yielding again, machining accuracy is high, and valve seat is not yielding, the deformation effects such as tolerance is little, the expansion upheaval of valve seat are little, the long service life of valve seat.
2, 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.
3, the utility model structural strength is high, good seal performance, and valve seat adopts assembling mode of colding pressing to install, and obviously promote packaging efficiency, and structure is simple, valve 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 that the A-A of Fig. 2 is to enlarged section.
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.
The highi degree of accuracy butterfly valve that a kind of sealing surface is removable, comprise valve body 3, valve rod 2, valve seat 4, dish plate 5 and handle 1, in the middle part of valve body, radial direction is provided with a valve rod, and valve rod lower end is coaxially installed with one and is arranged on conical bearing 6 in valve seat, 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, on the valve rod in valve seat, radial direction is provided with dish plate.
Valve outer wall spaced radial is shaped with multiple mounting plate 9, and the plurality of mounting plate is all shaped with standard-sized mounting hole, for being connected with piping flange.
Innovative point of the present utility model is:
Described valve rod is positive six prism structures, and valve plate 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 dish plate smooth surface is smooth, the rotation under the twisting force of valve rod of dish plate, thus the keying of control valve.Dish plate outer rim adopts polishing treatment micro-hemisphere face, reduces operational torque, and when ensureing sealing, dish plate and valve seat is sealed and matched.
Described valve seat is the one-body molded cylinder barrel shaped structure made of rubber, and this valve seat adopts assembling mode of colding pressing to install, and in the middle part of 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 8, and this edge bulge loop is inlaid in the made valve seat mounting groove in the axial two ends of valve body.
