The type of Gate valve
Jul 17, 2018

The type of sluice gate can be divided into wedge-shaped gate type gate valve and parallel gate valve, and the wedge type gate type gate valve can be divided into single gate type, double sluice plate type and elastic gate type, and parallel gate type gate valve can be divided into single sluice type and double sluice type plate type. According to the screw thread position of the stem, it can be divided into two kinds: the open gate valve and the hidden pole gate valve.


The installation and maintenance of gate valves should be paid attention to:


Handwheel, handle and transmission mechanism are not allowed to be used for lifting, and no collision is strictly prohibited.


The double gate valve should be installed vertically (that is, the valve stem is in a vertical position and the handwheel is at the top).


Gate valve with bypass valve should be opened before opening the bypass valve to balance the pressure difference between inlet and outlet and reduce opening force.


The gate valve with belt transmission mechanism is installed according to the requirements of the product manual.


If the valve is frequently switched on, lubricate at least once a month.
