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

merchandise design principles 
one.shell:
Dagong shall at least adopt the shell made of ductile iron, which can bear the extreme load in the earthquake location, 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. 
two.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 high-grade grease or lubricating oil which makes the worm  gear wear- resistant continuously, prolongs the service life of the product future enhances 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.
3.mechanical restrict and seal:
The travel limit screw with an angle of -90°( ±5°)can be modified to satisfy the demands of the valve switch.the altering screw seal is realized by the invention patent of the university of the technologies,which can promise various environmental seals ,this sort of as large temperature ,minimal temperature,deep sea,large and lower force,continual strain and sturdy corrosion environment.in the increased safety amount,the protection cap can be utilized to accomplish double sealing.
four.Reduction gearbox:
the layout of the gear strives to make the root anxiety of the two wheels equivalent,to satisfy the instantaneous torque qualities when the valve is opened and shut,and to lengthen the use time period of the pinion.the major reduction equipment makes use of the large module cylindrical gear,and the planetary equipment is used to minimize the massive specification and high torque to accomplish the necessary enter torque.they can be employed for handwheel operation,sprocket operation and electric drive gearbox.the gearbox style have a specified room to meet the simultaneous deciphering time of the electrical installation when choosing distinct transmission ratios.
5.output flange:
The design standard of the output flange linked with the valve shall be in accordance with ISO 5211.every single specification gives numerous flange choices to meet up with the link specifications of the valve.
6.output shaft gap:
According to ISO 5211 normal ,the output push hole can be right tailored in diverse dimensions with no added machining to fulfill the assembly needs of the valve stem.Give different link methods,these kinds of as multi important link,diagonal sq. head,parallel square head,flat head,spline relationship,and so on.
seven.enter shaft for handwheel procedure:
for the input shaft of the gearbox operated by the hand wheel ,anti-corrosion defense treatment shall be carried out or the stainless steel materials shall be utilised immediately .the lock unit and 2-inch handwheel block driving parts can be specified .According to the valve torque,the wheel specification can be selected,so as to meet the specifications that the running pressure of the driving valve is not greater than that specified by the valve.
8.all merchandise are equipped with loc ept gadget:
It can be locked at any time when the site wants to meet up with the specifications of the wor ept conditions
