    物料切断阀

    物料切断阀是我公司引进美国ITT Engineered的最新技术,开发研制的新一代产品。广泛应用于建材、冶金、矿山、石油、化工、玻璃等行业的管道或气力输送系统中,作切断或调节用。

    This valve is the new designed product importing new technology of American company ITT Engineered. It 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

     

    结构特点:

    Structure characteristic:

    物料切断阀采用优质钢材焊接而成,其结构科学合理,紧凑独特,操作灵活,维护方便,密封性能可靠。其楔紧工作原理使插板越关越紧,使密封永远处于最佳状态。而插板一旦开启,马上与密封面脱离,以保证密封面不受磨损,且密封面敞开式,物料无法附着和沉积。此构造是密封的关键所在。W表示密封面为橡胶软密封,P表示密封面为合金硬密封。配用不同的传动装置满足不同工况需求。Z73为手轮传动,WZ73为蜗轮传动,DZ73为电动装置传动,QZ73为气动装置传动。

    The valve is welded in fine steel, having the features of compact and scientific structure, hand to operate, easy to maintenance and reliable sealing. 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. 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. Z73 denotes hand wheel drive, WZ73 denotes worm gear drive, DZ73 denotes electric device drive and QZ73 pneumatic device drive.

    工作原理:

    Working principle

    物料切断阀主要由阀体、插板、密封副、传动杆及传动装置等部件组成。手动物料切断阀由人工转动手轮,沿顺时针方向为关,逆时针方向为开。由旋转螺母带动传动杆作向上运动,使插板脱离密封面向上位移,直至全开,反之为关。蜗轮传动物料切断阀由人工转动蜗轮装置手轮,顺时针方向为关,逆时针方向为开,带动蜗轮副旋转从而带动传动杆向上运动,使插板全开,反之全关。电动物料切断阀由Z型电动装置得到指令动作旋转螺母带动传动杆作运动,使插板起到开关作用。气动物料切断阀由二位五通电磁换向阀控制,10A-5R气动推杆带动传动杆作往复运动,使插板起到开关作用。

    The valve is mainly made up of body, inserting disc, sealing pairs, transmission pole and transmission device etc. The hand wheel of the manual valve is rotated in clockwise and closes the valve, anticlockwise rotation means open. The transmission pole moves upwards and makes the disc separate from sealing surface and move upwards until the valve is fully opened. 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. 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. 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.
