Product model and function introduction:
Z41X-16Q soft seal elastic seat seal open rod ductile iron gate valve
The opening and closing part of the gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The rising stem gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled.
The gate has two sealing surfaces. The two sealing surfaces of the most commonly used gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50, and 2°52' when the medium temperature is not high. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its manufacturability and make up for the deviation of the sealing surface angle during processing. The plate is called an elastic gate.
The types of rising stem gate valves can be divided into wedge gate type gate valve and parallel gate gate valve according to the configuration of sealing surface. Wedge gate gate valve can be divided into: single gate type, double gate type and elastic gate type; parallel gate type Gate valve can be divided into single gate type and double gate type. According to the thread position of the valve stem, it can be divided into two types: open stem gate valve and dark stem gate valve.
When the rising stem gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, only relying on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, the gate must be forced against the valve seat by external force to ensure the tightness of the sealing surface.
