Abstract
The utility model relates to a rolling valve body sealing ring butterfly valve. The butterfly valve comprises a valve body, wherein the valve body is provided with a fluid inlet and a fluid outlet, the two sides of the valve body are respectively provided with a valve shaft base, each valve shaft base is provided with a valve shaft, and the inner periphery of the valve body is provided with a round ring valve body sealing base along the periphery; a butterfly plate matched with a valve base is arranged in the valve body and on the valve shaft, a butterfly plate rubber sealing ring is embedded at the outer periphery of the butterfly plate, and a metal valve body sealing ring is embedded on the valve body sealing base; and the valve body sealing base is a round dovetail groove along the inner periphery of the valve body, the valve body sealing ring is a metal lath ring embedded in the round dovetail groove by a rolling method, and a rubber seal strip is arranged between a metal lath and the dovetail groove. The valve body sealing base provided by the utility model is the round dovetail groove along the inner periphery of the valve body, the valve body sealing ring is the metal lath ring embedded in the round dovetail groove by the rolling method, the material usage of the metal valve body sealing ring is less, the manufacture process is simple, the installation is easy, and the expense is lower.
Description
Technical field
The utility model relates to the valve seal ring of a kind of butterfly valve, particularly a kind of butterfly valve.
Background technique
Butterfly valve has valve body; Valve body has the fluid inlet/outlet, and the both sides of valve body have the valve shaft seat respectively, is installed with valve shaft on the valve shaft seat; One side circumference of valve body inner circumference has the valve seal seat; In the valve body, be connected with the butterfly plate that matches with valve seat on the valve shaft, the butterfly plate excircle has the butterfly plate sealing seat, between valve seal seat and the butterfly plate sealing seat sealing pair is arranged; For the metal-seated butterfly valve, sealing pair by be embedded on the valve seal seat the metal valve body seal ring be embedded in butterfly plate rubber seal ring on the butterfly plate sealing seat and match and form.In the existing technology, the valve seal ring is in the butterfly valve of metallic packing ring, and the metal valve body seal ring is the stainless steel material seal ring of solid body; When making the metallic packing ring of solid body, material consumption is bigger, and metallic packing ring will be through turning and grinding; Complex manufacturing technology, expense are higher; When seal ring was installed, metallic packing ring will be embedded in metallic packing ring on the sealing seat with ring pressing plate and the screw that is uniformly distributed along the circumference, and installation bothers, expense is higher.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned deficiency, and the material consumption that proposes a kind of valve body metallic packing ring is less, the roll extrusion valve seal ring butterfly valve that preparation process is simple, install easily, expense is lower.
The utility model is realized with following method.
Roll extrusion valve seal ring butterfly valve has valve body, and valve body has the fluid inlet/outlet, and the both sides of valve body have the valve shaft seat respectively; Be installed with valve shaft on the valve shaft seat; The valve body inner circumference has the annular valve sealing seat along circumference, and in the valve body, be connected with the butterfly plate that matches with valve seat on the valve shaft, the butterfly plate excircle is embedded with the butterfly plate rubber seal ring; Be embedded with the metal valve body seal ring on the valve seal seat; The valve seal seat is the ring dovetail groove along the valve body inner circumference, and the valve seal ring is that the method with roll extrusion is embedded in the metal lath ring in the ring dovetail groove, between at the bottom of metal lath and the dovetail groove, rubber weather strip is arranged.
The valve seal seat of the utility model is the ring dovetail groove along the valve body inner circumference; The valve seal ring is that the method with roll extrusion is embedded in the metal lath ring in the ring dovetail groove; The material consumption of valve body metallic packing ring is less, and preparation process is simple, installation is easy, expense is lower.
Below in conjunction with accompanying drawing, the utility model is done explanation further.
Description of drawings
Fig. 1 is that the master of a kind of roll extrusion valve seal ring butterfly valve of proposing according to the invention scheme of the utility model looks schematic representation;
Fig. 2 is the I place enlarged diagram of Fig. 1;
Fig. 3 is that the method for roll extrusion is embedded in the schematic representation in the dovetail groove to metal lath;
Fig. 4 is the schematic representation after metal lath is embedded in the dovetail groove.
Embodiment
Among Fig. 1, Fig. 2, roll extrusion valve seal ring butterfly valve has valve body 1, and valve body has fluid inlet/ outlet 2,3; The both sides of valve body have valve shaft seat 4,5 respectively, are installed with valve shaft 6 on the valve shaft seat, and the valve body inner circumference has the annular valve sealing seat 7 along circumference; In the valve body, be connected with the butterfly plate 8 that matches with valve seat on the valve shaft; The butterfly plate excircle is embedded with butterfly plate rubber seal ring 9, is embedded with metal valve body seal ring 10 on the valve seal seat, and the valve seal seat is the ring dovetail groove along the valve body inner circumference; The valve seal ring is that the method with roll extrusion is embedded in the metal lath ring in the ring dovetail groove, between at the bottom of metal lath and the dovetail groove, rubber weather strip 11 is arranged.
Among Fig. 3, Fig. 4; When on the valve body of the utility model, the valve seal ring being installed; Earlier in valve body, make the annulus 7 that the cross section is a dove-tail along the inner circumference car of valve body; Get sectional dimension again and get the metal lath 10 that matches with the sectional dimension of dovetail groove, be bent into the metal lath annulus that matches with the dove-tail annulus of valve body inner circumference to metal lath, in the dove-tail annulus, place O shape rubber seal ring 11; Be placed on the metal lath annulus on the dove-tail annulus mouth, compress into the dove-tail annulus to the metal lath annulus with pressure roller 12.
