Problems solved by technology

Other prior art systems utilizing electric actuators generally cannot open and close fast enough to mitigate the hazardous conditions inherent in the process of drumming the coke out of the head during the decoking process
Such prior art devices cannot operate within the size constraints imposed by the environment at the bottom of the coke drum and cannot produce consistent thrust output over the life of the actuator and do not allow for predictable maintenance and can create unsafe condition

Abstract

The present invention features a coke drum de-heading system. The de-header valve is equipped with a valve body, a gate, a transmission system and an actuator. Actuation of the valve closure functions to open and close the de-header valve.

Description

technical field [0001] The present invention relates to devices and systems for opening and closing valves coupled to vessels, either directly or through intermediate cartridges, which may contain liquids, distillates, or loose debris by-products of manufacturing processes, such as polysaccharides from oil refining processes. coke of various types; and the present invention relates to methods for unheading a vessel using said apparatus or system. Specifically, the present invention relates to a valve actuator system that includes an actuator, a gearbox assembly, and a transmission assembly designed to open and close attached to a coke drum so that during decoking Header valve for easy coke removal. Background technique [0002] An electric actuator is mounted on the valve, which uses an external power source to move the valve to a desired position in response to a signal. Motors of various electric types use AC or DC electricity to drive gear sets to produce desired torque...
