Slurry valve is widely used in petroleum, chemical, thermal power plants and other oil products, water, steam pipelines as the opening and closing device for connecting or cutting off the medium in the pipeline.
Open and close by rotating the wheel to complete the action, the valve is mainly composed of left and right valve body, U-ring, gate, steel nut, stem, bracket, hand wheel and other components.
When the valve rotates clockwise, the valve closes; otherwise, it opens the valve.
Slurry valve is based on the absorption and digestion of advanced valve body technology at home and abroad on the valve body structure, sealing form, drive device and electrical control aspects were further updated.
The product is simple in structure, small in size, light in weight, small in flow resistance, easy to settle in the valve body, and convenient in installation. It also has manual and electrohydraulic operation functions.
The opening and closing parts of the gate valve are gate plates. The direction of movement of the gate plate is perpendicular to the direction of the fluid. The slurry 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 mode gate valves form wedges, and the wedge angle varies with the valve parameters, usually 50, and 2° 52†when the medium temperature is not high. Wedge type slurry valve The gate can be made into a whole, called a rigid gate; it can also be made of a gate that can produce a slight amount of deformation, in order to improve its processability, make up for the deviation of the sealing surface angle in the processing process, this kind of gate is called elasticity. gate.
When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, relying on the medium pressure to press the sealing surface of the gate plate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most of the gate valves are forced to seal, that is, when the valve is closed, it is necessary to force the gate plate to press against the valve seat in order to ensure the sealing of the sealing surface.
