The gate valve is a shutter of the opening and closing member. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted and throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually, the sealing surface will weld the metal material to increase the wear resistance, such as surfacing 1Cr13, STL6, stainless steel, and the like. The gate has a rigid gate and an elastic gate. According to the gate, the gate valve is divided into a rigid gate valve and a resilient gate valve.
1. The flow resistance is small. The inner medium passage of the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.
2. It is more labor-saving when opening and closing. Compared with the shut-off valve, the direction of movement of the ram is perpendicular to the direction of flow of the medium, whether it is open or closed.
3. High height, long opening and closing time. The opening and closing stroke of the shutter is large, and the lifting is performed by the screw.
Erosion and abrasion are easily caused between the sealing surfaces, and maintenance is difficult. The external dimensions are large, and a certain space is required for opening, and the opening and closing time is long. The structure is more complicated.
Longzhu not only has world-class resin sand founding production lines, digital controlled lathes, machining centers and other advanced processing devices, but also boasts perfect process facilities, standardized manufacturing and division of labor based on specialization; and has formed a complete production and manufacturing process. Furthermore, Longzhu has invested a huge sum in technical transformation and has set up a special new product R&D center.
