Description

The secondary butterfly valve of a kind of metal-rubber seal
Technical field
The utility model relates to a kind of metal-rubber sealing pair butterfly valve, particularly a kind of metal-rubber sealing pair butterfly valve body seal ring and butterfly plate seal ring.
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 metal-rubber sealing pair butterfly valve, sealing pair is by being embedded in a metallic packing ring on the sealing seat and being embedded in rubber seal ring on another sealing seat and matching and form.In the existing technology, the metallic packing ring of metal-rubber sealing pair butterfly valve and rubber seal ring all are the seal rings of solid body, when making seal ring; Material consumption is bigger; Metallic packing ring will be through turning and grinding, and complex manufacturing technology, expense are higher, when seal ring is installed; Metallic packing ring and rubber seal ring will be embedded in seal 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 it is less to propose a kind of seal ring material consumption, the secondary butterfly valve of metal-rubber seal that preparation process is simple, install easily, expense is lower.
The utility model is realized with following method.
The secondary butterfly valve of metal-rubber seal 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, a 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, and the valve seal seat is that the cross section is the ring of dove-tail, and the cross section is that the dovetail groove of dove-tail ring is embedded with the valve body rubber seal ring; The valve body rubber seal ring is that the cross section is the leg-of-mutton hollow valve body rubber seal ring of fillet; The excircle of hollow valve body rubber seal ring is evenly equipped with gum-injecting port, is filled with resin in hollow valve body rubber seal ring hollow, and the butterfly plate sealing seat is the arc edge at the butterfly plate excircle; Have along the groove at arc edge on the arc edge of butterfly plate excircle; The side of butterfly plate excircle is evenly equipped with the screw that communicates with groove, and the shutoff screw is arranged in the screw, is embedded with the butterfly plate seal ring on the arc edge of butterfly plate excircle; The butterfly plate seal ring is to be the annulus of arc with the cross section that the sheet metal bar is rolled into, and is filled with resin in the groove at arc edge, upper edge, butterfly plate excircle arc edge.
Be filled with resin in hollow valve body rubber seal ring hollow; Make the valve body rubber seal ring become the entity rubber seal ring; Be embedded in the dovetail groove; Prevent that the valve body rubber seal ring from coming off, be filled with resin in the groove at arc edge, upper edge, butterfly plate excircle arc edge, make the butterfly plate seal ring adhere on the butterfly plate sealing seat securely and let to keep sealing between butterfly plate seal ring and the butterfly plate sealing seat.
The valve seal seat of the utility model is that the cross section is the ring of dove-tail; The valve body rubber seal ring is that the cross section that is embedded in the ring of dove-tail is the leg-of-mutton rubber seal ring of fillet; The butterfly plate sealing seat is the arc edge at the butterfly plate excircle, and the butterfly plate seal ring is that to be embedded in the cross section that is rolled on the arc edge, with the sheet metal bar be the annulus of arc.The material consumption of making valve seal ring and butterfly plate seal ring is less; Metallic packing ring is to form with the roll extrusion of sheet metal bar; Preparation process is simple, expense is lower, and when seal ring was installed, metallic packing ring can be embedded in the method for roll extrusion on the butterfly plate sealing seat at an easy rate; Rubber seal ring also can be embedded on the valve seal seat of dove-tail at an easy rate, and installation is simple, expense is lower.
Below in conjunction with accompanying drawing, the utility model is done explanation further.
