Example Embodiment

[0014] figure 1 Among them, 1-gas generating unit, 2-gas tank input valve, 3-gas tank, 4-gas output fan, 5-gas user. When the storage capacity of the gas tank 3 rises to the upper limit of safety, the monitoring system issues an alarm and triggers the protection interlock, closes the gas tank input valve 2, so that the gas storage volume of the gas tank 3 no longer rises; when the gas storage volume drops to the lower limit of the safety of the gas tank 3, The monitoring system issues an alarm and triggers the protection interlock to trip and stop the output fan 4 of the gas tank, so that the gas storage capacity of the gas tank no longer drops.

[0015] figure 2 Middle, 4-gas pipe network, 5-valve between gas tank and gas pipe network (input and output shared), 3-gas tank. When the storage capacity of the gas tank 3 rises to the upper limit of safety, the monitoring system issues an alarm and triggers the protection interlock, closes the valve 5 between the gas tank and the gas...

Abstract

The invention discloses a gas tank storage capacity overload detection and control interlocking device comprising a steel rope, a pulley, an indicating sign with gas storage capacity scales, a pointer, a weight and a proximity sensor. The device is capable of judging the high limit and low limit of the gas tank storage capacity, the high limit and low limit serve as the judgment basis for mutual authentication with gas tank monitoring system single tank instrument analog quantity parameters, the gas tank storage capacity overlimit judgment and interlocking control can be completed, the gas tank is guaranteed operating in a safe capacity range, the defects on economics and timeliness since multiple monitoring system tank instruments are configured or overlimit is verified and judged by acquiring the gas tank storage pressure are solved, and the device is simple in structure, reliable to use, low in cost, convenient to maintain and durable.

Description

technical field [0001] The invention belongs to the field of automatic control of gas cabinets, in particular to an interlocking device for detection and control of excess gas storage capacity in gas cabinets. Background technique [0002] The gas storage capacity is an important parameter for the safe operation of the gas cabinet. In operation and management, the safe capacity of the gas cabinet refers to the gas storage capacity not greater than 90% of the rated storage capacity of the gas cabinet, and not lower than 10% of the rated storage capacity; higher or lower than the specified value is overrun. [0003] There are two conventional monitoring methods for gas storage capacity. One is the counter instrument of the automatic monitoring system, which uses laser, radar reflection and other means to measure the height of the gas tank piston, and converts it into gas storage capacity through program calculation. This method displays the storage capacity of the gas tan...
