AI Technical Summary
The small axial thickness of cryogenic gate valves limits the installation space for actuators and protective sleeves, making effective installation difficult within a limited space.
An installation platform is fitted onto the upper end of the valve body's mounting section. The mounting platform is fixed to the mounting section by a combination of plug-in and welding, forming an independent spatial expansion structure that can accommodate actuators and protective sleeves of different sizes.
It expands the installation space of the valve body, ensures stable installation of the actuator and protective sleeve, avoids transmission jamming or sealing failure caused by eccentricity, and improves the accuracy of installation and the stability of connection.
