When open-stem gate valve closes, the sealing surface can be sealed only by medium pressure, that is, only by medium
pressure to press the sealing surface of the gate to the seat on the other side to ensure the sealing surface, which is self-
sealing. Most gate valves are forced to seal, that is, when the valve closes, the gate must be forced to the seat by external
force to ensure the sealing surface.

The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form wedges.
The wedge angle varies with the valve parameters, usually 50, and the medium temperature is 2 52'. Wedge gate valve can
be made into a whole, called rigid gate; it can also be made into a gate that can produce slight deformation to improve its
workability and make up for the deviation of sealing surface angle in the process of processing. This kind of gate is called
elastic gate.

The types of open bar gate valves can be divided into wedge gate valves and parallel gate valves according to the
configuration of sealing surface. Wedge gate valves can be divided into single gate type, double gate type and elastic gate
type. Parallel gate valves can be divided into single gate type and double gate type. According to the threaded position of the
valve stem, it can be divided into two kinds: open stem gate valve and dark stem gate valve.

When open-stem gate valve closes, the sealing surface can be sealed only by medium pressure, that is, only by medium
pressure to press the sealing surface of the gate to the seat on the other side to ensure the sealing surface, which is self-
sealing. Most gate valves are forced to seal, that is, when the valve closes, the gate must be forced to the seat by external
force to ensure the sealing surface.
