Soft seal gate valve


Gate Valve Series: Light rod elastic seat seal gate valve, dark rod signal elastic seat seal gate valve, buried elastic seat seal gate valve, and dark rod elastic seat seal gate valve
The opening and closing part of the gate valve is a gate plate. The direction of movement of the gate plate is perpendicular to the direction of the flow. The gate valve can only be fully opened and full, and adjustment and throttling cannot be performed. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form a wedge, and the wedge angle varies with the valve parameters, typically 50, and 425°C when the medium temperature is not high. The type of gate valve can be divided into wedge type gate valve and parallel gate type gate valve according to the configuration of sealing surface. Wedge gate type gate valve can be further divided into: single gate type, double gate type and elastic gate type; parallel gate type gate valve Divided into a single gate and double gate plate type. Divided according to the thread position of the valve stem, it can be divided into two kinds: open rod gate valve and dark rod gate valve.
Gate valve installation and maintenance
1. Handwheels, handles and transmission mechanisms are not allowed to be lifted, and collisions are strictly prohibited.
2. The double gate valve shall be installed vertically (ie, the valve stem is in a vertical position and the handwheel is at the top).
3. The gate valve with bypass valve should open the bypass valve before opening (to balance the pressure difference between the inlet and outlet and reduce the opening force). 4. The gate valve with transmission mechanism should be installed according to the instructions of the product manual.
5, if the valve is used regularly, lubricate at least once a month.
