Technical field
The utility model relates to three eccentric metal hard sealed butterfly damper.
Background technique
At present, the butterfly valve that be used for doing to regulate flow on the pipeline of different medium, blocks or connect fluid mainly is made up of butterfly valve assembly, valve component etc.But when maintenance, butterfly valve is pulled down from pipeline, spended time is big, and maintenance is not easy.On flowing medium pipelines such as oil, petrochemical industry, some process pipelines break down or regular maintenance needs to stop using for a long time is unallowed, must carry out on-line maintenance.
Summary of the invention
It is a kind of simple in structure, compact, reasonable that technical problem to be solved in the utility model is to provide, and sealing is reliable, opens freely, and long service life can realize with the last dress formula three eccentric metal hard sealed butterfly damper that is pressed in the line maintenance.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of dress formula three eccentric metal hard sealed butterfly damper of going up, comprise valve body, butterfly plate, valve rod, valve seat, valve gap, valve seat is directly processed on valve body one side runner, the valve body top is provided with greater than the butterfly plate sized opening, valve gap is removably disposed in the opening top of valve body, valve rod is arranged on rotationally on the valve gap and with valve bonnet seal and cooperates, the bottom of valve body is provided with the rotating fulcrum that matches with valve rod, the runner center of valve rod rotatingshaft misalignment valve body, butterfly plate is installed on the valve rod, the runner center of butterfly plate diameter axis runout valve body, valve seat is provided with internal conical surface, and the periphery of butterfly plate is provided with the outer conical surface that matches with the valve seat internal conical surface, and the flap that cooperates with valve base sealing is housed on the outer conical surface of butterfly plate.
It is simple in structure, compact, reasonable that the utility model three-way switch valve has, and sealing is reliable, opens freely, and long service life can be implemented in tape pressurized maintenance characteristics.
The utility model will be further described below in conjunction with the drawings and specific embodiments.

Embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of dress formula three eccentric metal hard sealed butterfly damper of going up, comprise valve body 1, butterfly plate 3, valve rod 4, valve seat 5, valve gap 6, valve seat 5 is directly processed on valve body 1 one side runners, valve body 1 top is provided with greater than butterfly plate 3 sized opening, valve gap 6 is removably disposed in the opening top of valve body 1, valve rod 4 is arranged on rotationally on the valve gap 6 and with valve gap 6 and is sealed and matched, the bottom of valve body 1 is provided with the rotating fulcrum 7 that matches with valve rod 4, the runner center of valve rod 4 rotatingshaft misalignment valve bodies 1, butterfly plate 3 is installed on the valve rod 4, the runner center of butterfly plate 3 diameter axis runout valve bodies 1, valve seat 5 is provided with internal conical surface 9, and the periphery of butterfly plate 3 is provided with the outer conical surface 10 that matches with valve seat 5 internal conical surfaces 9, and the flap 2 that is sealed and matched with valve seat 5 is housed on the outer conical surface 10 of butterfly plate 3.As a kind of concrete application mode of the present utility model, the opening of valve body 1 top is a rectangle, and the length of rectangular aperture is greater than the diameter of butterfly plate 3, and valve gap 6 is a rectangle, and rectangle valve gap 6 and valve body 1 are fixedlyed connected by flange.The length of rectangular aperture is convenient to butterfly plate 3 and is taken out greater than the diameter of butterfly plate 3, connects and composes dress formula structure by flange between valve gap 6 and the valve body 1.When valve need overhaul, it need not be pulled down from pipeline, as long as just spend few time to open valve gap 6 to connect valve rod 4 band butterfly plates 3 and take out in the valve pocket and carry out maintenance operation.And can seal recovery pipeline band suitable for reading rapidly after taking out butterfly plate 3 assembly parties and press operation, the benefit loss that the repairing valve is caused is reduced to minimum degree.Butterfly plate 3 has three eccentric structures and is meant: the runner center (as shown in Figure 2) of valve rod 4 rotatingshaft misalignment valve bodies 1; The outer conical surface 10 of butterfly plate 3 matches with the internal conical surface 9 of valve seat 5 and constitutes off-centre; The runner center (as shown in Figure 3) of butterfly plate 3 diameter axis runout valve bodies 1.After butterfly plate 3 adopts three eccentric structures, internal conical surface 9 and outer conical surface 10 sealing surfaces are opened and closed throw off the angle of friction of angle, realize that butterfly plate 3 promptly separates at unlatching moment sealing surface, closes the effect that contact promptly seals greater than seal face materials.This sealing configuration has alleviated butterfly plate 3 greatly and has opened and closed moment friction torque force, has prolonged working life, has reached to open and close purpose easily.While will occur closing more tight more when valve closing, can realize self-locking, prevent butterfly plate 3 position excessively.The flap 2 that is sealed and matched with valve seat 5 is housed on the outer conical surface 10 of butterfly plate 3, flap 2 is rationally arranged, make butterfly plate 3 rigidity pure, thereby guaranteed the reliability of sealing.Flap 2 can be fixed on the butterfly plate 3 by pressure ring 8, and assurance flap 2 can be stablized, be fixed on reliably on the butterfly plate 3, and is simultaneously easy to process.
As a kind of concrete application mode of the present utility model, flap 2 adopts soft T type both sides multilayer stainless steel sheets to form, and has the two-fold advantage of metal hard-sealing and soft seal, no matter under low temperature and high-temperature condition, all has the sealability of zero seepage.Flap 2 is selected stainless steel material for use, has high temperature resistant, high pressure, wear-resisting, corrosion resistant characteristics.
The utility model is simple, compact and reasonable for structure; Can be implemented in the tape pressurized maintenance; Flap 2 is hard soft lamination, has hard soft double seal, no matter under low temperature still is worst hot case, all has excellent sealing performance; Because adopt three eccentric structures, valve seat and butterfly plate almost do not have friction, thereby have increased working life, sealability, reach zero leakage; Open and close that moment is little, flexible operation, lowering energy-saving, long service life; High temperature resistant, high pressure resistant, corrosion-resistant using scope is wide, selects different materials for use, can be applicable to media such as water, sewage, seawater, air, steam, coal gas, inflammable gas, Korrosionsmedium, oily crystalline substance and food respectively.
