I would like to ask the experts about the connection methods for gate valves
Thread Content
Dear experts, I would like to ask: what are the various connection methods available for flanged gate valves, between the gate and the screw rod? Which one is the best? Or should different connection methods be used for different media?
This depends on the process requirements and the usage environment.
Conventional wedge gate valves are all connected in a T-shaped manner
For T-type connections, in some cases a plate is welded directly to the screw rod, while in other cases holes are drilled in the screw rod and a T-shaped sleeve is connected to it using pins
It depends on what kind of organization you work for. If you’re in a design institute, they generally don’t deal with how the screw and the valve disc are connected; all they need to know is the pressure, diameter, type, and material of the valve. As for the method of connection, the method specified by the design institute is taken as the default connection method between the valve and the pipeline. If you are a valve manufacturing company, then how to connect the screw and the valve disc falls under mechanical design, which is beyond my expertise; it would be more appropriate to consult the mechanical engineering department for that. For general valve models and connection types, please refer to JB/T 308-2004 \"Method for Coding Valve Models\"
