What is a P/V valve? What about the high speed exhaust?
Thread Content
I would like to ask for advice from experts. When making the "Ship and Shore Safety Checklist", one of the items is to check whether the P/V valve or high-speed exhaust device on the ship is working normally. I would like to ask what the P/V valve is specifically? What about the high speed exhaust? What are their specific functions? Is it common on all ships, and where exactly is it located? Thank you everyone~~!
Generally speaking, PV valve refers to pressure control valve, which is a pressure control valve. It is used to control the pressure of fluids in pipelines. It is used in various situations such as fuel, steam, fire water, etc. It will be used on any ship. Of course, it will not be used on simple ones such as rafts and canoes.
The "Ship and Shore Safety Checklist" I made seems to be that the P/V valve is mainly used to balance the pressure inside and outside the oil tank. I want to know the specific name of its position on the ship.
