Chemical valve machinery for remote operation

Abstract: At the 3rd China Petroleum and Chemical Leakless Pump Technology and Application Forum held in Xi'an recently, the participating experts and petrochemical enterprises showed great interest in the remote drive system of valve machinery introduced by Shanghai Rocker Interlock Technology Co., Ltd. . It is reported that this valve mechanical remote drive system developed by Rocker Company has passed expert appraisal in mid-August. Remote operation of valves within safe distance in high-risk areas such as petrochemicals and mines will become a reality.

According to Yu Guozhong, general manager of Rock, the valve remote drive system consists of an operating mechanism, a flexible drive shaft, and an actuator. The key component is a ring-shaped flexible flexible shaft that can transmit torque to a remote valve up to 50 meters away. It can flexibly and easily bypass obstacles or cross partitions to achieve a specified torque. Remote operation, driving force more than 200 kg.

Through technical breakthroughs, Rock has solved the problem of the consistency of the entire flexible shaft (including butt joints) and the adaptability to a tensile strength of not less than 150 kg. At the same time, special anti-friction structures and anti-corrosion materials are used to ensure that the flexible shaft can withstand the torque required for opening and closing the valve and use in harsh environments. The original man-made control is changed to the rigid control of the safety system to prevent the on-site human operation. The safety hazards are applicable to dangerous areas that are not easily accessible to operators, such as petrochemicals, oil fields, nuclear power, offshore platforms, mines, and underground water supply systems. In addition to valve control, the system can also be extended to mechanical remote operations within the safety distance of other equipment.

Luoke Company has successively provided comprehensive safety interlocking equipment for Fushun Petrochemical Polyethylene and Butadiene, Huajin Ethylene Plants and PetroChina Liaohe Oilfield Qinhuangdao-Shenyang Natural Gas Pipeline Project, which has been well received by users.
