Sealed plug valve

The sealing structure of a sealed plug valve can be divided into soft sealing and hard sealing structures. Pneumatic plug valves have the characteristics of good processability and compact structure. The sealed valve seat is designed with an active structural performance automatic compensation function, which has a long service life.

Sealed plug valve; It is the main equipment for controlling the flow of powder, crystalline granules, and small particle materials. Pneumatic plug valves are widely used in industries such as metallurgy, mining, building materials, grain, and chemical engineering. The gate 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. Pneumatic plug-in valves are welded from carbon steel and are widely used in industries such as metallurgy, carbon, chemical, and building materials. The flue gas purification system and flue gas pipeline system are mainly used for flue gas regulation and switching.

Structural characteristics of sealed plug valve:

The pneumatic one-way gate valve adopts a steel plate welding structure and a self resetting mechanism for the counterweight rod, with a compact structure and stable operation. Pneumatic plug-in plate valve and pneumatic bi-directional plate gate valve are mainly composed of a frame, a gate plate, and a cylinder. The gas source drives the cylinder through an electromagnetic directional valve, which in turn drives the gate to move horizontally back and forth, achieving the purpose of valve opening and closing.

The gate valve has a simple structure, light weight, flexible operation, easy loading and unloading, made of carbon steel, good performance, and long service life; The screws and nuts adopt a soft cover structure, which is not affected by external dust.

Scope of application and advantages:

1. Pneumatic plug valve is the main equipment for controlling the flow rate of powder, grain and small particle materials. Pneumatic plug valves are widely used in industries such as metallurgy, mining, building materials, grain, and chemical engineering. The gate 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. Pneumatic plug-in valves are welded from carbon steel and are widely used in industries such as metallurgy, carbon, chemical, and building materials. The flue gas purification system and flue gas pipeline system are mainly used for flue gas regulation and switching.

2. Pneumatic plug valve has low flow resistance, small size, light weight, easy maintenance, and wide application. The sealing structure of plug-in valves can be divided into soft sealing and hard sealing structures.

3. Pneumatic plug valves are installed at the outlets or pipelines of various powder particle gas hoppers, and the flow rate of materials can also be controlled by adjusting the opening size. Electrical and pneumatic devices can be used for plug valve drive devices. Pneumatic plug valves are suitable for industries such as metallurgy, chemical, and grain, and are ideal material partitioning equipment.

4. Pneumatic plug valve is a system used for conveying fly ash and powder drying materials. It can also be installed under the ash hopper of thermal power plants such as economizers, air preheaters, dry dust collectors, and flues. It can also be used in conjunction with electric feeders, with a working temperature of up to 600 ° C. The plug-in valve is lightweight, small in size, and has no fly ash leakage. Our company can produce pneumatic plug valves, electric plug valves, and pneumatic plug valves with inlet and outlet diameters of 100-600. We can also design and manufacture non-standard size plug valves according to user requirements.
