Problems solved by technology

[0002] Traditional high temperature resistant butterfly valves have low sealing performance and are made of general materials. They are not resistant to high temperature and are not suitable for high temperature media
Moreover, the valve plate, the rotating shaft, etc. are prone to being stuck at high temperature, and the rotation is not flexible, which shortens the service life and reduces the production efficiency.

Embodiment Construction

[0008] Such as figure 1 As shown, the electric ultra-high temperature butterfly valve includes a circular valve body 1, a valve shaft 2 and a butterfly plate 3 arranged in the circular valve body 1, the butterfly plate 3 rotates around the valve shaft 2, and the butterfly plate 3 A sealing ring 4 is provided between the circular valve body 1 , an electric actuator 5 is mounted on the outside of the circular valve body 1 , and the electric actuator 1 is connected to the end of the valve shaft 2 . Wherein, the ultra-high temperature butterfly valve is an alloy steel butterfly valve. In this embodiment, since the high-temperature butterfly valve is welded with alloy steel, it has the advantages of high temperature resistance, wear resistance, strong rigidity, small heat loss, and flexible operation. It can be installed horizontally or vertically. Realize automatic control operation. When in use, the electric actuator receives the control signal of the upper instrument such as tr...

Abstract

The invention relates to the technical field of butterfly valve equipment, in particular to an electric ultrahigh-temperature butterfly valve. The electric ultrahigh-temperature butterfly valve comprises a circular valve body, a valve shaft and a butterfly plate, wherein the valve shaft is arranged inside the circular valve body; the butterfly plate rotates around valve shaft; a sealing ring is arranged between the butterfly plate and the circular valve body; an electric actuator is mounted on the outer side the circular valve body and connected with an end part of the valve shaft. By adopting the structure, the electric ultrahigh-temperature butterfly valve has the advantages of high temperature resistance, wear resistance, strong rigidity, less heat loss, excellent heat preservation effects, reasonable structure, accurate indication direction, long service life and the like and is flexible in operation and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of butterfly valve equipment, in particular to an electric ultra-high temperature butterfly valve. Background technique [0002] Traditional high temperature resistant butterfly valves have low sealing performance and are made of general materials. They are not resistant to high temperature and are not suitable for high temperature media. Moreover, the valve plate, the rotating shaft, etc. are prone to being stuck at high temperature, and the rotation is not flexible, which shortens the service life and reduces the production efficiency. Contents of the invention [0003] The purpose of the present invention is to provide an electric ultra-high temperature butterfly valve with reasonable design, simple structure, high temperature resistance, wear resistance, flexible operation, clear indication direction, convenient maintenance and long service life. [0004] In order to solve the problems existing in the...
