worm gearbox:DGAB series torque from 400-48000N.m,
                             D collection torque from 2000-180000 N.m

solution style principles 
one.shell:
Dagong shall at least adopt the shell made of ductile iron, which can bear the extreme load in the earthquake area, with IP67 sealing grade, and the exposed parts shall be corrosion-resistant or the surface shall be protected with gray epoxy resin. Available in carbon steel, stainless steel, corrosion-resistant alloy and high and low temperature
 environment materials, including deep sea worm gear. 
2.Worm:
  wear-resistant nodular cast iron  worm gear is  matched with alloy steel worm gear, manufactured with improved
 process data after multiple process evaluation,
and equipped with higher-grade grease or lubricating oil which makes the worm  gear wear- resistant continuously, prolongs the service life of the product future improves the switching torque characteristic and transmission efficiency applicable to the valve, and reduces the input torque. The large reduction ratio makes each pair of worm gears suitable for the self-locking capacity required by the valve to control the valve. Bronze worm gear and alloy steel worm gear are available.
three.mechanical limit and seal:
The travel limit screw with an angle of -90°( ±5°)can be modified to fulfill the demands of the valve change.the altering screw seal is understood by the creation patent of the university of the technologies,which can ensure various environmental seals ,these kinds of as higher temperature ,minimal temperature,deep sea,substantial and reduced strain,constant pressure and strong corrosion setting.in the increased protection amount,the security cap can be utilized to obtain double sealing.
four.Reduction gearbox:
the layout of the equipment strives to make the root pressure of the two wheels equal,to fulfill the instantaneous torque attributes when the valve is opened and shut,and to lengthen the use time period of the pinion.the principal reduction equipment uses the huge module cylindrical equipment,and the planetary equipment is employed to decrease the large specification and high torque to accomplish the needed enter torque.they can be employed for handwheel procedure,sprocket procedure and electrical push gearbox.the gearbox design and style have a certain place to meet the simultaneous deciphering time of the electrical installation when picking distinct transmission ratios.
5.output flange:
The design standard of the output flange related with the valve shall be in accordance with ISO 5211.each and every specification offers multiple flange choices to satisfy the connection needs of the valve.
six.output shaft hole:
According to ISO 5211 standard ,the output drive gap can be right custom-made in diverse dimensions without having additional machining to satisfy the assembly needs of the valve stem.Give a variety of link approaches,such as multi crucial link,diagonal square head,parallel square head,flat head,spline connection,and many others.
7.enter shaft for handwheel operation:
for the input shaft of the gearbox operated by the hand wheel ,anti-corrosion protection therapy shall be carried out or the stainless steel materials shall be used directly .the lock gadget and 2-inch handwheel block driving elements can be specified .In accordance to the valve torque,the wheel specification can be picked,so as to meet up with the demands that the functioning drive of the driving valve is not better than that specified by the valve.
eight.all products are outfitted with loc ept device:
It can be locked at any time when the internet site demands to meet up with the specifications of the wor ept conditions
Be aware:we are fully commited to steady advancement of our merchandise and producing processes.Samples are topic to alter without prior observe.
