Problems solved by technology

[0003] Most of the existing triple-eccentric butterfly valves are manually opened or closed, and cannot be driven by a motor, resulting in inconvenient use, and the motor cannot be easily disassembled, resulting in inconvenience in maintenance or replacement. Therefore, we propose a floating seal type triple-eccentric butterfly valve. to solve the above problems

Abstract

The invention discloses a floating seal type triple eccentric butterfly valve, which comprises a valve body, a disc plate is rotatably installed in the valve body, a valve seat is welded on one side of the valve body, and a valve seat is welded on a side far away from the valve body. The installation seat, and the side of the installation seat away from the valve seat is provided with an installation groove, and the periphery of the installation groove is provided with a plurality of card slots opened on the side of the installation seat away from the valve seat, and the card slots are connected to the installation groove, The periphery of the installation groove is provided with a sealing strip that is fixedly installed on the side of the installation seat away from the valve seat, and both sides of the installation seat are welded with fixing blocks, and the opposite sides of the two fixing blocks are provided with an open end. The chute is provided with a cover plate between the two fixed blocks. The invention can be driven by a motor, and the motor can be easily disassembled, so that the maintenance or replacement of the motor can be facilitated, the structure is simple, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a floating sealing type triple eccentric butterfly valve. Background technique [0002] In the use of butterfly valves, in order to be resistant to high temperatures, hard seals must be used, but the leakage is large; to zero leakage, soft seals must be used, but they are not resistant to high temperatures; Secondary eccentricity forms a triple eccentric butterfly valve. [0003] Most of the existing triple-eccentric butterfly valves are manually opened or closed, and cannot be driven by a motor, resulting in inconvenient use, and the motor cannot be easily disassembled, resulting in inconvenience in maintenance or replacement. Therefore, we propose a floating seal type triple-eccentric butterfly valve. used to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a floating ...
