Abstract
An elastic seal butterfly valve of inlaying rolling forming metal seal ring consists of a valve body and a butterfly plate, a seal pair is arranged between the valve body and the butterfly plate, one of the seal elements in the seal pair is a seal rubber seal ring, the other seal element is a metal seal ring which is an equal wall thickness ring groove formed by rolling thin stainless steel plate, the open direction of the equal wall thickness ring groove is the same with the plane where the metal seal ring is arranged. The metal seal ring is inlayed on the valve body or on the butterfly plate; correspondingly, the rubber seal ring is arranged on the butterfly plate or the valve body. A ring seal metrical groove is arranged between the butterfly plate or the valve body where the metal seal ring is inlayed and metal seal ring, and the seal material groove is provided with a seal material therein. The metal seal ring of the utility model is made by the thin stainless steel plate in the method of roller bending forming, compared with the metal seal ring which is an elastic seal butterfly valve made by the method of thick plate chip processing, the utility model has the advantages of saving material, simple process, and low manufacture cost.
Description
Technical field
The utility model relates to a kind of elastic packing butterfly valve, particularly a kind of metallic packing ring of elastic packing butterfly valve.
Background technique
Between the butterfly plate of elastic packing butterfly valve and the valve body sealing pair is arranged, a Sealing in the sealing pair is a rubber seal ring, and another Sealing is a metallic packing ring.In the prior art, the metallic packing ring of elastic packing butterfly valve is to make with the smear metal method for processing with thicker corrosion resistant plate, the section configuration of the metallic packing ring that smear metal processes is irregular polygonal, the metallic packing ring that smear metal processes is embedded on the butterfly plate or valve body of elastic packing butterfly valve, correspondingly, rubber seal ring and metallic packing ring are installed on the valve body of elastic packing butterfly valve or the butterfly plate and form sealing pair.The metallic packing ring of this elastic packing butterfly valve is to process with the slab smear metal, and its section configuration is irregular polygonal, and material consumption is more man-hour big, that processing is used, makes the manufacturing expense of elastic packing butterfly valve higher.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, a kind of elastic packing butterfly valve of inlaying the rolling-formed metal seal ring that the material consumption that proposes a kind of metallic packing ring is little, processing is simple, manufacturing expense is lower.
The utility model is realized with the following method.
Originally the elastic packing butterfly valve of inlaying the rolling-formed metal seal ring has valve body and butterfly plate, between valve body and the butterfly plate sealing pair is arranged, a Sealing in the sealing pair is a rubber seal ring, another Sealing is a metallic packing ring, metallic packing ring is with thin stainless steel lath roll forming, the metallic packing ring of roll forming is to wait the wall thickness circular groove, bottom land outer side surface Deng the wall thickness circular groove is a sealing surface, opening direction Deng the wall thickness circular groove is identical with the plane at metallic packing ring place, metallic packing ring is embedded on the valve body or is embedded on the butterfly plate, correspondingly rubber seal ring is mounted on the butterfly plate or is installed on the valve body, on the butterfly plate or valve body of embedded with metal seal ring, the annular packing material groove is arranged between metallic packing ring and butterfly plate or the valve body, in the annular packing material groove sealing material is arranged.The notch of metallic packing ring being used in the metallic packing ring ring is embedded in butterfly plate, and the notch of metallic packing ring being used to outside the metallic packing ring ring is embedded in valve body.
Metallic packing ring of the present utility model is to make with the method for thin stainless steel lath roll forming, is to compare with the elastic packing butterfly valve that slab smear metal method for processing is made with metallic packing ring, save material, processing simply, manufacturing expense is low.
Below in conjunction with accompanying drawing, the utility model is further described.
