Manual gate valve

Manual gate valve

Pneumatic gate valve is a kind of main control equipment for the flow or transportation of powder, crystal and granular materials, granular materials and small materials. It is widely used in metallurgy, mining, building materials, grain, chemical industry and other industries to control the change or rapid cut-off of flow. The pneumatic gate valve has the advantages of simple structure, flexible operation, light weight and no jamming. It is especially suitable for the transportation and flow regulation of all kinds of solid materials and about 50mm block and mass materials. The installation is not limited by angle, the operation is convenient, and the scale can be adjusted at any time. Structural features: simple structure, flexible operation, light weight, no jamming and fast cutting. It is especially suitable for all kinds of solids, powders and materials without viscosity Φ The conveying and flow adjustment of 10mm granular material and crystalline granular material are not limited by angle, easy to operate, and the opening can be adjusted at any time. It is mainly used for warehouse top, bottom, import and export of building materials, metallurgy, mining, electric power, chemical industry, glass, light industry, grain and other industries. It is an ideal equipment for controlling large flow change, frequent start and rapid cut-off.
Pneumatic single-way and two-way gate valve, also known as manual knife gate valve, knife gate valve is a valve in which the gate and valve seat are always in close contact and sealed. Its principle is that the gate is provided with a circular opening of the size of the diameter, and the circular opening of the gate is separated and matched with the diameter through the opening and closing of the gate. The valve has the advantages that the valve body has no groove in the diameter, the medium will not be blocked, and has full diameter flow characteristics. Its sealing structure can be divided into soft sealing and hard sealing structures. The penetrating knife gate valve has the characteristics of excellent structure, good manufacturability and compact structure. The sealing valve seat is designed as a movable structure and has the functions of anti-wear and automatic compensation, so it has a longer service life. In the process of closing and opening, the valve seat has been close to the gate, which makes the opening and closing force of the valve stable, and has the characteristics of cutting off the medium.
