Abstract
The utility model discloses a three-dimensional compensation and two-direction metal sealing butterfly valve. A sealing pair is arranged between a butterfly plate and a valve body and comprises a rigid entity butterfly plate sealing ring directly embedded in the outer circumference of the butterfly plate and a valve body sealing ring connected to the inner circumference of the valve body through a three-dimensional compensation assembly. The three-dimensional compensation assembly is provided with a rigid ring, one end of the rigid ring is connected to the inner circumference of the valve body, one end of an elastic ring is connected to the other end of the rigid ring, and the valve body sealing ring is connected to the other end of the elastic ring, wherein the elastic ring is made of a steel plate in a bending mode, and the section of the elastic ring is of a V shape. According to the three-dimensional compensation and two-direction metal sealing butterfly valve, the valve body sealing ring is connected to the inner circumference of the valve body through the rigid ring and the elastic ring which are connected, after the butterfly plate is closed in position, the valve body sealing ring deforms in a three-dimensional mode under the action of the three-dimensional compensation assembly along the circumference of the butterfly plate sealing ring and is attached to the butterfly plate sealing ring to achieve tight fitting of sealing edges; after the butterfly plate deforms when bearing forward-direction pressure and reverse-direction pressure, the valve body sealing ring can deform in the three-dimensional mode under the action of the three-dimensional compensation assembly along the circumference of the butterfly plate sealing ring and keep tight fitting of the sealing edges.
Description
Technical field
The utility model relates to the sealing pair of a kind of bidirectional metallic seal butterfly valve, particularly a kind of bidirectional metallic seal butterfly valve.
Background technique
Bidirectional metallic seal butterfly valve has cylinder valve, the valve shaft vertical with valve axis arranged on valve body, on valve shaft in valve body, butterfly plate is arranged, between butterfly plate and valve body, sealing pair is arranged, sealing pair has at the butterfly plate seal ring of butterfly plate excircle with at the valve seal ring of valve body inner circumference.Bidirectional metallic seal butterfly valve can be used for the use occasion of two way sealed after closing.
In prior art, the butterfly plate seal ring of bidirectional metallic seal butterfly valve is the rigidity entity butterfly plate seal ring that directly is embedded in the butterfly plate excircle, and the valve seal ring of bidirectional metallic seal butterfly valve is also the rigidity entity valve body seal ring that directly is embedded in the valve body inner circumference.
The butterfly plate seal ring of bidirectional metallic seal butterfly valve and valve seal ring are the rigidity entity seal rings of directly inlaying, and need larger seal pressure could realize two way sealed.This bidirectional metallic seal butterfly valve is because seal pressure is larger, and during opening and closing, driving force is larger, the serious wear of seal ring; In addition, butterfly plate seal ring and valve seal ring are that cross section is less, and the rigid material ring that diameter is larger has certain shape position error when making and install, this deviation can make the seal lip laminating imprecision of butterfly plate seal ring and valve seal ring, and seal lip laminating imprecision can produce leakage.
Summary of the invention
The seal lip that the purpose of this utility model is that the driving force that proposes a kind of opening and closing is less, seal wears is less in order to overcome above-mentioned deficiency, close rear butterfly plate seal ring and the valve seal ring tight three-dimensional compensate for bidirectional metallic sealing butterfly valve of fitting.
The utility model is realized with the following method.
Three-dimensional compensate for bidirectional metallic sealing butterfly valve has cylinder valve, the valve shaft vertical with valve axis arranged on valve body, on valve shaft in valve body, butterfly plate is arranged, between butterfly plate and valve body, sealing pair is arranged, sealing pair has the rigidity entity butterfly plate seal ring that directly is embedded in the butterfly plate excircle and the valve seal ring that is connected in the valve body inner circumference by three-dimensional compensation assembly, three-dimensional compensation assembly has an end to be connected in the rigidity ring of valve body inner circumference, the other end of rigidity ring is connected with the end that the cross section bent with steel plate is the elastic ring of V-arrangement, and the valve seal ring is connected in the other end of elastic ring.
Valve seal ring of the present utility model is connected in the valve body inner circumference by three-dimensional compensation assembly, three-dimensional compensation assembly has connected rigidity ring and elastic ring, the rigidity ring is connected in the valve body inner circumference, and the valve seal ring is connected on elastic ring, less in the driving force of opening and closing, seal wears is less, the utility model in use, when butterfly valve cuts out, butterfly plate is after closing and putting in place fully, because the valve seal ring is to be connected on the elastic ring of three-dimensional compensation assembly, the valve seal ring is made 3 D stereo along butterfly plate seal ring circumference and is out of shape and fits tightly and on the butterfly plate seal ring, make seal lip laminating tight under the effect of three-dimensional compensation assembly, the utility model in use, butterfly plate just is subject to, backpressure and after deforming, the valve seal ring also can be done the 3 D stereo distortion along butterfly plate seal ring circumference and keep fitting tightly the tight sealing of maintenance on the butterfly plate seal ring under the effect of three-dimensional compensation assembly.
Below in conjunction with accompanying drawing, the utility model is further described.
The accompanying drawing explanation
Fig. 1 looks schematic diagram according to the master of a kind of three-dimensional compensate for bidirectional metallic sealing butterfly valve of scheme of the invention proposition of the present utility model;
Fig. 2 is that schematic diagram cuts open in the side-looking office of Fig. 1;
Fig. 3 is the I place enlarged diagram of Fig. 2.
Embodiment
In Fig. 1 ~ Fig. 3, three-dimensional compensate for bidirectional metallic sealing butterfly valve has cylinder valve 1, the valve shaft vertical with valve axis 2 arranged on valve body, on valve shaft in valve body, butterfly plate 3 is arranged, sealing pair 4 is arranged between butterfly plate and valve body, sealing pair has the rigidity entity butterfly plate seal ring 5 that directly is embedded in the butterfly plate excircle and the valve seal ring 7 that is connected in the valve body inner circumference by three-dimensional compensation assembly 6, three-dimensional compensation assembly has an end to be connected in the rigidity ring 8 of valve body inner circumference, the other end of rigidity ring is connected with the end that the cross section bent with steel plate is the elastic ring 9 of V-arrangement, the valve seal ring is connected in the other end of elastic ring.
The rigidity ring of three-dimensional compensation assembly can positioningly be connected in the valve body inner circumference, also can be connected in the valve body inner circumference with bolt.The three-dimensional compensate for bidirectional metallic sealing butterfly valve that three-dimensional compensation assembly is connected in the valve body inner circumference with bolt in use, adjust the turnover of three-dimensional compensation assembly construction bolt, can regulate the gap between butterfly plate seal ring and valve seal ring, the seal pressure of gap affects the utility model when closing between butterfly plate seal ring and valve seal ring.
By adjusting the turnover of three-dimensional compensation assembly construction bolt, can make to work under the seal pressure of the utility model the best when closing.Sealing configuration of the present utility model is applicable to manufacture two eccentric or three eccentric structure metallic sealing butterfly valves.
In Fig. 2, Fig. 3, the three-dimensional compensation assembly of three-dimensional compensate for bidirectional metallic sealing butterfly valve is to be connected in the valve body inner circumference with bolt 10.
