Spherical hinge-The Yangzhou Bernard valve automatic control Equip

The ball type connection hinge connection accessories for automatic control of the actuator, and regulatory agencies. It uses a ball bearing structure control of flexible, accurate, and reversing the angle of the advantages of the hinge installation, easy adjustment, safe and reliable. Therefore, it is widely used in the automatic control system of electric power, petrochemical, metallurgy, mining, textile and other industries.

     The product developed in the absorption of the German company Siemens advantages of similar products, and combine the characteristics of our instrument.

Second, the product structure features

      1 The product result of the selection ball bearing structure can be flexible to withstand the pressure from the different surface.

      2, the product and actuator connections both cone and straight shank, to expand the use of the instrument surface.

      3, the spherical connection hinge left and right hand thread connection is convenient and reliable, the adjustable range.

      4, connect the hinge to a fully enclosed structure, convenient maintenance.

Third, the installation

      1, prior to installation should be accurate distance measurement location of the connection (the adjustment nut in the middle position) in order to determine the length of the connecting tube. Connecting pipe welding, L, D, nuts and you should do to shorten or lengthen the connecting rod properly adjusted, and then tighten the lock nut.

      2, the first hinge mounted on the control rod of the actuator output shaft lever and regulatory agencies, such as the selection of a cone connection should be dedicated reamer output shaft lever and control rod hinge into the 1:10 hole, re-connection.

      Installed, the application manually even move commissioning, such as flexible rotation before use.

Fourth, the use of maintenance

This product uses a fully enclosed structure. Therefore, a longer period of maintenance, generally six months injection of sodium-based lubricant. Each overhaul period to check the cleaning time, such as severe wear should be replaced, the general life of more than 5 years.
