Globe Valve Easy To Manufacture, Easy Maintenance
Nov 1, 2017
Globe Valve, also known as the door, is the use of a wide range of valves, it is popular, because the opening and closing process between the sealing surface friction is small, more durable, open height is not large, easy to manufacture Convenient, not only for low pressure, but also for high pressure.
The closing principle of the shut-off valve is to rely on the pressure of the valve, so that the valve sealing surface and the valve seat sealing surface close to prevent the media circulation. Only one-way flow of the valve, the installation of directional. Cut valve structure length is greater than the gate valve, while the fluid resistance, long-term operation, the sealing reliability is not strong.
In the DC or Y-shaped globe valve, the flow path of the valve body is slanted with the main flow path, so that the degree of damage of the flow state is smaller than that of the conventional shut-off valve, and the pressure loss through the instrument valve is correspondingly small.
Use of Globe Valve:
The valve stem of the globe valve is perpendicular to the sealing surface of the valve seat. The stem is open or closed with a relatively short stroke and has a very reliable cut-off action, making this instrument valve ideal for cutting or regulating media and throttling.
Once the valve is open, its valve seat and the valve seal surface is no longer between the contact, and has a very reliable cutting action, together that the instrument valve is very suitable as a medium cut or adjust and Throttle use.
In addition, once the stop valve is in the open state, its valve seat and the valve seal surface is no longer between the contact, so its sealing surface mechanical wear less, because most of the valve seat valve and the valve is easier to repair Or replace the sealing element without the need to remove the entire instrument valve from the pipeline, which for the instrument valve and pipeline welding into one place is very suitable. The flow direction of the medium through such instruments when the valve has changed, so the flow resistance of the valve is higher than other instrument valves.
