What is an inverted seal gate valve?
An inverted seal gate valve means that there is a sealing surface in the middle of the valve stem and a sealing seat inside the bonnet. When fully opened, they come in contact with each other to play a sealing role, reduce fluid erosion to the packing, and extend the service life of the packing. Reduce the possibility of leakage. Generally, gate valves and globe valves have reverse sealing requirements.
In the fully open state of the inverted seal gate valve, there is a sealing structure at the connection between the disc and the valve stem, and inside the valve stem and the bonnet (ie the bottom of the stuffing box). When fully open, the two contact and squeeze together to seal It can reduce the erosion of the packing in the stuffing box by the internal pressure, prolong the service life of the packing, and reduce the possibility of leakage. Generally, gate valves and globe valves have reverse sealing requirements.
The gate valve is one of the most commonly used valves for shut-off medium circulation. Its sealing element is the valve plate, so the gate valve is also called the gate valve. Most gate valves are mandatory sealing valves, that is, when closing the valve, pressure must be applied to the valve plate. When the gate valve is fully open, the flow path is straight, and the valve plate is hardly scoured by the medium. The inverted seal gate valve is equipped with an inverted seal device. After the valve is fully opened, an inverted seal is formed, and the packing can be replaced under the normal operation of the system.
