Abstract

The invention discloses a butterfly valve for a seal ring of a rolling valve, comprising a valve body provided with a fluid inlet and a fluid outlet, wherein a valve shaft seat is respectively arranged on two sides of the valve body; a valve shaft is penetrated onto the valve shaft seats; a ring-shaped valve body sealing seat is arranged along the inner circumference of the valve body; butterfly plates matched with a valve seat are connected in the valve body and on the valve shaft; a rubber butterfly plate sealing ring is embedded in the outer circumference of the butterfly plate; a metal valve body sealing ring is embedded in the valve body sealing seat; the valve body sealing seat is a ring-shaped dovetail groove along the inner circumference of the valve body, and the valve body sealing ring is a metal plate ring embedded in the ring-shaped dovetail groove through a rolling method; and a rubber sealing strip is arranged between the metal plate ring and the ring-shaped dovetail groove. According to the invention, the valve body sealing seat is the ring-shaped dovetail groove along the inner circumference of the valve body and the valve body sealing ring is the metal plate ring embedded in the ring-shaped dovetail groove through the rolling method, and the metal valve body sealing ring is made of a small amount of materials. The butterfly valve for the seal ring of the rolling valve has the advantages of simple manufacturing process, easy installation and low cost.

Description

Roll extrusion valve seal ring butterfly valve
Technical field
The present invention 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 objective of the invention is in order to overcome above-mentioned deficiency, 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, installation is easy, expense is lower.
The present invention realizes 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.
Valve seal seat of the present invention 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 present invention 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 invention scheme of the present invention 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 valve body of the present invention, 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.

Claims (1)

1. a roll extrusion valve seal ring butterfly valve has valve body, and valve body has the fluid inlet/outlet; The both sides of valve body have the valve shaft seat respectively, are installed with valve shaft on the valve shaft seat, and the valve body inner circumference has the annular valve sealing seat along circumference; 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, is embedded with the metal valve body seal ring on the valve seal seat, it is characterized in that: 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 is arranged.
