Product Description: Slide gate valve


This valve is used to cut off or adjust valve, which is applied in pipe or pneumatic transportation system in building material, metallurgy, mining, oil, chemical and glass industries,etc. Structure characteristic: 1.The valve is welded in fine steel, having the features of compact and scientific structure, hand to operate, easy to maintenance and reliable sealing.2.The working principle is choking, the sealing is always in the best state while the disc is closed. The disc separates from sealing surface when it is opened, which avoids abrasion of the sealing surface. The sealing surface is in open state and the material cannot cohere or deposit, which the key to the sealing.3.W means the sealing surface is rubber soft sealing, P means the sealing surface is alloy hard sealing. It can meet different requirement of working conditions equipped with different transmission devices.4.Z73 denotes hand wheel drive, WZ73 denotes worm gear drive, DZ73 denotes electric device drive and QZ73 pneumatic device drive.  Working principle: 1.The valve is mainly made up of body, inserting disc, sealing pairs, transmission pole and transmission device,etc.2.The hand wheel of the manual valve is rotated in clockwise and closes the valve, anticlockwise rotation means open.3.The transmission pole moves upwards and makes the disc separate from sealing surface and move upwards until the valve is fully opened.4.The hand wheel of worm gear drive valve is rotated by hand. Clockwise rotation means close and anticlockwise means open. The transmission pole moves upward, the worm gear pairs rotate until the disc is fully opened.5.Type Z electric device of electric valve receives the order and rotates nut to drive the transmission pole in order to open or close the disc.6.The pneumatic valve is controlled by two-bite five-way electromagnetism reversal valve. Type 10A-5R pneumatic draw stem drives the transmission pole move reciprocally to open or close the disc.
