Abstract
The utility model discloses a high-performance three-eccentric center butterfly valve. The high-performance three-eccentric center butterfly valve comprises a valve body. The upper portion of the valve body is provided with an upper valve rod, padding is arranged in the movable space between the upper portion of the upper valve rod and the valve body, the upper portion of the padding is provided with a padding gland, and the upper portion of the padding gland is provided with a padding pressing plate fixed through a bolt. The middle of the valve body is provided with a valve plate of a three-eccentric center structure. The lower portion of the valve body is provided with a lower valve rod, and the lower portion of the lower valve rod is fixedly connected with the valve body through a fixing pressing plate. A bearing is arranged between the upper valve rod and the valve body, a bearing is arranged between the lower valve rod and the valve body, and thrusting sealing structures are arranged between the ends of the bearings and the valve body. According to the high-performance three-eccentric center butterfly valve, the valve plate of the three-eccentric center structure is arranged in the middle of the valve body, the high-performance three-eccentric center butterfly valve has the advantage of being small in operating torque, and due to the fact that the thrusting sealing structures are arranged in the valve body, the valve plate cannot scratch the valve body when the valve is opened, and the sealing performance is better.
Description
Technical field
The utility model relates to a kind of high-performance three eccentric butterfly valve.
Background technique
Traditional butterfly valve is a visual plant in water-feeding & drainaging pipeline system, and along with the progress of industrial technology, structure and performance to butterfly valve are had higher requirement.Be widely used at present in the plumbing industrial fields such as municipal administration, oil, chemical industry, light industry, the kind of butterfly valve is a lot, comprises the soft sealing butterfly valve that adopts rubber seal and the hard seal butterfly valve that adopts metalwork sealing.
Existing three eccentric hard sealed flygates, its valve plate is all arranged on the bottom of valve body, owing to having space between valve plate and valve body, is difficult to realize sealing completely, and is not easy to realize two way sealed.And because the sealing configuration of three common eccentric hard sealed flygates belongs to pressure forced seal, so the operation moment of torsion in the time of valve opening and closing is large.
Model utility content
The utility model object is that the defect existing for prior art provides a kind of high-performance three eccentric butterfly valve.
The utility model for achieving the above object, adopt following technological scheme: a kind of high-performance three eccentric butterfly valve, comprise valve body, the top of described valve body is provided with upper valve rod, in activity space between the top of described upper valve rod and described valve body, be provided with filler, the top of described filler is provided with Gland, and the top of described Gland is provided with the hold-down grid being bolted; The middle part of described valve body is provided with the valve plate of three eccentric structures; The bottom of described valve body is provided with lower valve rod, and the bottom of described lower valve rod is fixedly connected with described valve body by stationary platen; Between described upper valve rod, lower valve rod and described valve body, be respectively arranged with bearing, between the end of described bearing and described valve body, be provided with thrust sealing configuration.
Further, described thrust sealing configuration is made up of thrust ring, seal ring and trim ring.
The beneficial effects of the utility model: the valve plate of three eccentric structures is arranged on valve body middle part by butterfly valve of the present utility model, there is the little feature of operation moment of torsion, and the thrust sealing configuration arranging in valve body makes valve in the time opening and closing, the valve plate valve body of can not swiping, better tightness, has greatly improved and can regulate and control ratio.
Brief description of the drawings
Fig. 1 structural representation of the present utility model.
Embodiment
Shown in Fig. 1, for a kind of high-performance three eccentric butterfly valve, comprise valve body 1, the top of described valve body 1 is provided with upper valve rod 2, in activity space between the top of described upper valve rod 2 and described valve body 1, be provided with filler 6, the top of described filler 6 is provided with Gland 7, and the top of described Gland 7 is provided with the hold-down grid 8 fixing by bolt 9; The middle part of described valve body 1 is provided with the valve plate 4 of three eccentric structures; The bottom of described valve body 1 is provided with lower valve rod 3, and the bottom of described lower valve rod 3 is fixedly connected with described valve body 1 by stationary platen 11; Three eccentric butterfly valve of the present utility model is respectively arranged with bearing 10 between described upper valve rod 2, lower valve rod 3 and described valve body 1, between the end of described bearing 10 and described valve body 1, is provided with thrust sealing configuration 5.Make valve in the time opening and closing at the thrust sealing configuration 5 of valve body 1 interior setting, the valve plate valve body of can not swiping, better tightness, has greatly improved and can regulate and control ratio.Wherein, described thrust sealing configuration 5 is made up of thrust ring, seal ring and trim ring.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
