APPARATUS FOR INDICATING THE OPENING DEGREE OF A NATURAL GAS REGULATOR, CAPABLE OF PREVENTING THE DEFORMATION OF AN INDICATOR ROD WHEN THE VALVE OPENING DEGREE INDICATING APPARATUS IS OPERATED

摘要

PURPOSE: An apparatus for indicating the opening degree of a natural gas regulator is provided to prevent the breakdown of a valve opening degree indicating apparatus due to the deformation of an indicator rod and to enable accurate system control by producing an accurate signal related to a valve opening degree.;CONSTITUTION: An apparatus for indicating the opening degree of a natural gas regulator comprises a mounting plate(100), a valve opening degree transmitter(110), and a rack and pinion unit(120). The mounting plate is installed on a regulator housing. The valve opening degree transmitter is installed at one side of the mounting plate. An actuator rod(111) is projected through the mounting plate onto the other side of the mounting plate. The rack and pinion unit connects the indicator load(12a) with the diaphragm in the regulator housing to the actuator rod of the valve opening degree transmitter. Depending on the rising level of the indicator load, the rack and pinion unit rotates the actuator rod.;COPYRIGHT KIPO 2010
