Steam trap in the steam heating system plays a role in preventing steam drainage, choose the right trap, can make the steam heating equipment to achieve the highest efficiency.
In the fluid piping system, the valve is the control element, its main role is to isolate the equipment and piping system, regulate the flow rate, prevent backflow, regulate and
1. Valve stem corrosion and protection
Main causes of valve stem corrosion:
The corrosion damage of the valve body is mainly caused by the corrosive medium, and the valve stem corrosion problem is mainly the packing.
Fixed shaft ball valve is commonly used on natural gas pipelines, and its general inspection method is: turn the valve to the fully open or fully closed position
Ball valve has many kinds of structure, but basically the same little difference, are the opening and closing parts for the round ball core, mainly by the valve seat, ball, sealing ring
In the thermal system, the thermal trap plays a very important role, and its performance directly affects the stability and energy efficiency of the steam system.
