YJD-B star loaderFeatures of yjd-b star unloader:It can also be designed and manufactured according to ...Application features of manual disc valve:
1. manual plug plate valve has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small volume, smooth passage, low resistance, easy installation, easy disassembly, etc., manual spiral gate valve can be installed horizontally or vertically, with anti-wear and long life of automatic compensation function.
2. In the normal use of manual insert valve, all transmission parts should be checked regularly and maintained with lubricating oil.
3. manual plug plate valve is often used with discharge device or bin matching, manual spiral gate valve flange connection is easy to install, the inlet and outlet have square and circular two kinds, according to the size of the diameter of dozens of specifications, widely used in metallurgy, carbon, chemical, building materials and other industries.
The diameter of manual spiral gate valve is matched with the feeding port of the discharging device, which is square and round.The advantage of this valve is that the valve body size no groove, the medium will not jam, and has the characteristics of full flow flow, suitable for the use of powder particle medium in the pipeline.The sealing structure of the sliding door can be divided into soft sealing and hard sealing.Good technology, compact structure and other characteristics, sealing valve seat for the active structure design, anti - wear and automatic compensation function, so long life.The valve seat moves closely with the gate during the closing and opening process of the plunger door, which makes the valve opening and closing force stable and has the characteristics of cutting off medium.The handwheel can be operated directly to open and close the valve.Manual disc valve, also known as manual screw gate valve, is usually used in conjunction with the discharger.It is mainly composed of frame, gate, screw rod, nut, hand wheel and other parts. By manually rotating the hand wheel, the screw rod drives the gate to move up and down along the horizontal side repeatedly, so that the manual insert valve can achieve the purpose of opening and closing.
