Manual gate valve

Manual gate valve is also called manual gate valve,which is usually used with discharger.The diameter of manual spiral gate valve matches the feed port of discharger,and there are two types:square and round.The advantage of this valve is that there is no groove in the valve body diameter,the medium will not be blocked,and it has full-diameter flow characteristics,which is suitable for use in pipelines with powder and granular media.The gate door sealing structure can be divided into soft seal and hard seal structure.It has good processability and compact structure.The sealing valve seat is designed as a movable structure,which has anti-wear and automatic compensation functions,so it has a long life.The gate door is always in close contact with the gate during the closing and opening process,so that the valve opening and closing force is stable,and it has the characteristics of cutting off the medium.The configuration of the handwheel can directly operate the handwheel to open and close the valve.

Structural characteristics and working principle of manual gate valve:

The manual gate valve is mainly composed of parts such as frame,gate,screw,nut,etc.The valve has a simple structure,flexible operation,light weight,no jamming,fast cutting,and is particularly suitable for the transportation and flow regulation of various types of non-viscous solids,powders,and granular materials less thanφ10mm,and granular materials.The installation of the manual one-way spiral gate is not restricted by angles.It is easy to operate and can adjust the opening at any time.The fluid resistance is small;the torque required for opening and closing is small;when fully open,the sealing surface is less eroded by the working medium than the stop valve;the shape and structure are relatively simple,and the manufacturing process is better.

Working principle:When the handwheel of the manual one-way spiral gate valve is turned clockwise to make the valve stem carry the valve stem nut,the gate slowly rises to full opening,and vice versa.

Manual gate valves are widely used in metallurgy,mining,building materials,and grain.Manual gate valves are usually used in conjunction with star-shaped dischargers or can be used alone.The diameter of the manual spiral gate valve matches the feed port of the discharger,and there are two types:square and round.

Features of manual gate valve:

1.The manual gate valve is installed on various pressurized powder and granular material pipelines to open and close.The operating pressure can reach 1MPa.

2.The manual gate valve has the characteristics of good sealing and no internal or external leakage.The easily worn parts are made of high quality materials.At the same time,the structure of the valve fully considers the characteristics of powder and granular materials.

3.The manual gate valve has a simple structure,flexible operation,light weight,no jamming,and is particularly suitable for the transportation and flow adjustment of various solid materials and block and lump materials of about 50mm.The installation is not limited by angles,easy to operate,and can be adjusted at any time.
