Problems solved by technology

There are many unreasonable points in the existing butterfly valve design structure, such as the connection support provided on the upper part of the valve body and the flange connection, which not only increases the connection link, but also increases the volume and production cost of the valve body; in addition, the existing Butterfly valves mostly use rubber sealing parts. Due to the limited characteristics of rubber, their high temperature resistance, high pressure performance and service life are lower than those of gate valves, ball valves, globe valves and other valves.
In addition, the sealing pressure ring is usually connected by bolts, the sealing and compression effect is not good, and it is inconvenient to disassemble and assemble.

Abstract

The present invention relates to a butterfly valve. It is made up by using valve body, valve plate, rotating shaft, shaft sleeve, positioning pin, seal ring, sealing gland, filling material, stuffing ring, upper flange, connection support and end cover. Said invention also provides their connection mode and the concrete structure of said butterfly valve. The above-mentioned elastic seal ring is made up by adopting teflon or modified teflon material.

Description

technical field [0001] The invention relates to a valve, in particular to a novel butterfly valve. Background technique [0002] At present, there are various types of industrial valves, which are widely used in chemical industry, food, water, electricity and other industries, and mainly play the role of flow regulation and cut-off of fluid medium. There are many unreasonable points in the existing butterfly valve design structure, such as the connection support provided on the upper part of the valve body and the flange connection, which not only increases the connection link, but also increases the volume and production cost of the valve body; in addition, the existing Butterfly valves mostly use rubber sealing parts. Due to the limited characteristics of rubber, their high temperature resistance, high pressure performance and service life are lower than those of gate valves, ball valves, globe valves and other valves. In addition, the sealing pressure ring is usually con...
