Overview and Features of Slide Gate Valve

Slide gate valve, also known as manual knife type gate valve, is a kind of gate and seat always close contact sealing valve, the principle is that the gate has a diameter of the round mouth, through the opening and closing of the gate to make the gate on the round mouth with the size of the completely separated and consistent action. This valve has the advantage that the valve body size has no groove, the medium will not be blocked, and has the full flow through the characteristics, the sealing structure can be divided into soft seal, hard seal structure. Through knife gate valve has the characteristics of precision structure, good manufacturability, compact structure and so on. The sealing seat is designed with movable structure, which has the function of anti-wear and automatic compensation, so it has a longer life. In the closing and opening process seat and gate have been close to the movement, so that the valve opening and closing force is stable, and has the characteristics of cutting media.

The scope of use of slide gate valve has extended to a wide range of industries. Coal preparation, gangue discharge and slag discharge from mine power plant. Developed to the city's sewage treatment, from the general industrial pipeline development to food, health, medicine and other professional pipeline system. Ultra-thin knife gate valve with its small size, small flow resistance, light weight, easy to install, easy to disassemble and other advantages completely solve the common gate valve, flat gate valve, ball valve, globe valve, regulating valve, butterfly valve and other valves flow resistance, weight, difficult to install, cover an area of large problems. With the advent of knife gate valves, a large number of universal shut-off valves and regulating valves have been replaced by knife gate valves. Today, the world's largest use of knife gate valves is the United States and Japan.

Manual slide gate valve features:

1. Manual gate valve is often used with unloading device or silo, manual screw gate valve with flange connection is easy to install, inlet and outlet has square and round two, according to the size of the diameter has dozens of specifications, widely used in metallurgy, carbon, chemical, building materials and other industries.

2. Manual gate valve has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small volume, smooth channel, small resistance, easy installation, easy disassembly, manual screw gate valve can be installed horizontally or vertically, with anti wear and automatic compensation function long life, etc.

3. The driving parts of the movable gate valve should be checked regularly during the normal use, and lubricating oil should be added for maintenance.
