Abstract
Floating metal seal butterfly valve has valve body, a rotating valve plate in the body, seal pair between valve body and valve plate. Seal pair includes valve plate sealing ring embedded in the outside circumference of the valve plate and valve body sealing ring embedded in the inside circumference of the valve body. The valve plate sealing ring and valve body sealing ring are all made of metal. Along with the circumference of the valve body laid radial grooves, in which the valve sealing ring is embedded. The diameter of Valve seal ring outside the valve body sealing circumference is less than the circumference of groove bottom circle of radial grooves, rubber seal rings lay on both sides of the valve seal ring and two sides of the radial grooves respectively. The utility model of valve seal ring can float radially and swing axially. even if a certain deviation exists in the processing and assembling of components of metal seal butterfly valve,the metal enclosed butterfly valve in the at to assemble after the butterfly valve This floating valve seal ring can guarantee valve plate seal ring fasten tight with the valve seal ring after the butterfly valve is assembled, to achieve zero leakage when it closes in the butterfly valve.
Description
Technical field
The utility model relates to the valve seal ring of a kind of metallic sealing butterfly valve, particularly a kind of metallic sealing butterfly valve.
Background technique
Butterfly valve is used for the particularly conveyance conduit of water of fluid, butterfly valve has valve body, rotatable valve plate is arranged in the valve body, between valve body and valve plate sealing pair is arranged, sealing pair is made up of the valve seal ring cooperation that is set in the valve plate seal ring on the valve plate excircle and be set on the valve body inner circumference, and the valve plate seal ring of metallic sealing butterfly valve and valve seal ring all are to make with metal.In the prior art, the valve seal ring of butterfly valve is that the location is connected on the valve body inner circumference, because the relevant parts of metallic sealing butterfly valve the time have certain deviation in processing and assembling, after being assembled into butterfly valve, when closing butterfly valve, this valve seal loop mapping is connected in butterfly valve on the valve body inner circumference can not guarantee that valve plate seal ring and valve seal loops close tightly when butterfly valve cuts out, and does not reach butterfly valve and zero reveals when closing.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind ofly to guarantee that when butterfly valve cuts out valve plate seal ring and valve seal loops close tightly, realizes a kind of floating metal sealing butterfly valve of butterfly valve zero leakage when closing.
The utility model is realized with the following method.
The floating metal sealing butterfly valve has valve body, rotatable valve plate is arranged in the valve body, between valve body and valve plate sealing pair is arranged, sealing pair has at valve plate seal ring on the valve plate excircle and the valve seal ring on the valve body inner circumference, the valve plate seal ring of metallic sealing butterfly valve and valve seal ring all are to make with metal, radial groove along circumference is arranged on the valve body inner circumference, the valve seal ring is set in the radial groove, valve seal ring excircle place diameter of a circle is less than the bottom land place diameter of a circle of radial groove, and two sides of the both sides of valve seal ring and radial groove have rubber seal ring respectively.
Radial groove along circumference is arranged on the utility model valve body inner circumference, the valve seal ring is set in the radial groove, valve seal ring excircle place diameter of a circle is less than the bottom land place diameter of a circle of radial groove, two sides of the both sides of valve seal ring and radial groove have rubber seal ring respectively, so the valve seal ring can radial-play and axial runout in the radial groove on the valve body inner circumference, we can say that also the valve seal ring can float in the radial groove on the valve body inner circumference, even the relevant parts of metallic sealing butterfly valve the time have certain deviation in processing and assembling, after being assembled into butterfly valve, this unsteady valve seal ring can guarantee that valve plate seal ring and valve seal loops close tightly, realizes butterfly valve zero leakage when closing.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is the main cross-sectional schematic of floating metal sealing butterfly valve;
Fig. 2 is the local enlarged diagram in I place of Fig. 1;
Fig. 3 is that stepped valve seal ring is at the local enlarged diagram in I place;
Fig. 4 is that section is that the valve seal ring of dumbbell-like shape is at the local enlarged diagram in I place.
Embodiment
Fig. 1, among Fig. 2, the floating metal sealing butterfly valve has valve body 1, rotatable valve plate 2 is arranged in the valve body, between valve body and valve plate sealing pair is arranged, sealing pair has at valve plate seal ring 3 on the valve plate excircle and the valve seal ring 4 on the valve body inner circumference, the valve plate seal ring of metallic sealing butterfly valve and valve seal ring all are to make with metal, radial groove 5 along circumference is arranged on the valve body inner circumference, the valve seal ring is set in the radial groove, valve seal ring excircle place diameter of a circle is less than the bottom land place diameter of a circle of radial groove, and two sides of the both sides of valve seal ring and radial groove have rubber seal ring 6 respectively.
Above-mentioned valve seal ring is the identical valve seal ring of thickness.The valve seal ring also can be the different stepped valve seal ring of thickness, also can be that section is the valve seal ring of dumbbell-like shape.
Among Fig. 3, the valve seal ring is stepped valve seal ring 7, and the thickness of ring lip part 8 is less than the thickness of valve seal ring outer ring portion 9 in the valve seal ring.
Among Fig. 4, the section of valve seal ring is the valve seal ring 10 of dumbbell-like shape.
Claims (4)
