Coupling dome valve accessories copper sleeve

Basic concepts
The copper sleeve of coupling dome valve accessories is a very important part of the dome valve components. It is usually a sleeve-like structure made of copper or copper alloy, which is installed at a specific position of the coupling or dome valve to play key roles such as supporting and reducing friction.
Material properties
Good wear resistance: Copper material itself has good wear resistance. During the frequent opening and closing actions of the dome valve, the copper sleeve can withstand the friction caused by the relative movement between the shaft and the sleeve, reducing wear and tear on the components. For example, when the coupling drives the valve stem of a dome valve to move, the copper sleeve can effectively prevent damage due to direct contact friction between the valve stem and its mounting hole.
Excellent self-lubricating properties: The copper sleeve has certain self-lubricating properties. This is because during the friction process of copper materials, a microscopic lubricating film will be formed on the surface, which can reduce the friction coefficient. This is very important for the smooth operation of the dome valve, especially when there is no external lubrication system or insufficient lubrication. The self-lubricating property of the copper sleeve can ensure the normal operation of the valve.
Good thermal conductivity: Copper is a good conductor of heat. During the operation of the dome valve, heat may be generated due to factors such as friction or medium temperature. The copper sleeve can quickly conduct heat away and prevent local overheating. For example, when the temperature of components increases due to long-term operation of the valve, the copper sleeve can transfer the heat to the surrounding environment or other components, thereby protecting the key structures inside the valve.
Reflection in the coupling
Reduce shaft wear: Rotational or axial movement of the shaft is common in couplings. As a support component of the shaft, the copper sleeve can make the contact between the shaft and other components more reasonable. It can provide a relatively smooth supporting surface, reduce wear of the shaft during rotation or movement, and extend the service life of the shaft.
Precise positioning function: The copper sleeve facilitates precise installation and positioning of the shaft. By tightly fitting with the shaft and mounting base, it ensures that the shaft maintains the correct position during movement, thereby ensuring the power transmission accuracy of the coupling. For example, in high-precision transmission systems, the positioning function of copper sleeves can effectively reduce deviations during power transmission.
