The high platform ball valve is a kind of ball valve that is widely used. The closing part of the high platform ball valve is a sphere, which rotates around the center line of the valve body to achieve the function of opening or closing. It can change the flow direction of the medium and cut off in the pipeline. Function. When faced with the selection of different pipeline projects, what principles do we need to know? Let’s share and understand through the following aspects:
◎ For the pipelines and storage equipment of refined oil, when choosing the high platform ball valve of flange connection type
◎ For pipeline engineering of low temperature medium, when choosing a low temperature ball valve with a valve cover
◎ In the chemical pipeline system with corrosive media such as acid and alkali, when choosing a stainless steel ball valve with a valve seat sealing ring
◎ On the pipelines of city gas and natural gas, use the floating ball valve with flange connection and internal thread connection
◎ On the pipeline system of the catalytic cracking unit of the oil refining unit, the lifting rod type ball valve can be selected.
◎ For the main pipeline of oil and natural gas, if the pipeline needs to be cleaned, choose the high platform ball valve with full diameter and full welded structure;
