manual slide gate valve

The manual plug valve is the main equipment for controlling the flow of powder, crystalline particles, and small particles. Manual plug-in valves are widely used in industries such as metallurgy, mining, building materials, grain, and chemical engineering. The manual plug-in valve is equipped with electric, pneumatic, and electro-hydraulic push rods as driving devices, making it an ideal equipment for controlling flow rate and cutting off quickly. This series of manual plug-in valves is made of high-quality carbon steel welded together. The manual plug-in valve has a compact structure, stable performance, small leakage, and is characterized by easy operation, flexible action, and labor-saving. It can work normally in high temperature, high dust, and strong magnetic environments.

Manual plug-in valves are mostly used in conjunction with unloaders and are divided into two types: square mouth and round mouth. The type of manual plug-in valve port should be selected according to the shape of the unloader.

Manual plug-in valves have the advantages of simple and compact structure, customized according to demand, excellent sealing, lightweight and flexible operation, small volume, smooth channel, low resistance, easy installation, and easy disassembly. Manual plug-in valves can be installed horizontally or vertically, and have the characteristics of anti wear and automatic compensation, long service life, etc. The sealing structure of manual plug-in valve can be divided into soft sealing and hard sealing structures. The sealed valve seat is designed with a movable structure, which has anti wear and automatic compensation functions, resulting in a relatively long service life.

During the closing and opening process of the manual plug valve, the valve seat and gate always move closely together, making the valve opening and closing force stable and having the characteristics of cutting off the medium. Configuring a handwheel allows for direct operation of the handwheel to open and close valves.

Manual plug valve, also known as manual spiral gate valve or manual spiral plug valve, is mainly composed of frame, gate plate, screw rod, nut, handwheel and other parts. By manually rotating the handwheel, the screw rod drives the gate plate to move up and down along the horizontal plane repeatedly, enabling the manual plug valve to achieve the purpose of opening and closing.

Installation and instructions for manual plug-in valve:

Before installing the plug-in valve, it is necessary to check the valve chamber and sealing surface, and no dirt or sand particles are allowed to adhere to them;

2. The bolts at each connection point should be tightened evenly;

3. Check that the filling part is tightly pressed to protect both the sealing of the filling and the flexibility of the gate opening;

Before installing the valve, users should verify the valve model, connection size, and pay attention to the flow direction of the medium to ensure consistency with the valve requirements;

5. When installing valves, users should reserve space for valve actuation;

6. The wiring of the driving device must be carried out according to the circuit diagram;

7. The plug-in valve should be regularly maintained and should not be bumped or squeezed at will to avoid affecting the sealing.
