Can Gate Valves and Globe Valves Be Used Interchangeably?
Dec , 15 2023
Structurally Gate valves can rely on medium pressure to tightly close the sealing surface, thereby achieving the effect of no leakage. When opening and closing, the sealing surface of the valve core and valve seat always come into contact and rub against each other, so the sealing surface is prone to wear. When the gate valve is close, the pressure difference between the front and back of the pipe...

How to Distinguish between Rising Stem Gate Valves and Non-Rising Stem Gate Valves?
Dec , 15 2023
1. Non rising stem gate valve: The stem nut is located inside the valve body and in direct contact with the medium. When opening and closing the gate, rotate the valve stem to achieve this. The advantage of this structure is that the height of the gate valve remains constant, so the installation space is small, making it suitable for gate valves with large diameters or limited installation space. ...

Transformer: Why stack the core?
Dec , 30 2022
The design of the magnetic core does not allow any current to flow. However, it is a conductive loop that undergoes a changing magnetic field, so small currents are induced in it-these are called "eddy currents." Laminated cores reduce it to a minimum because they interfere with the effective transmission of energy from the primary coil to the secondary coil. Eddy currents cause energy loss f...
