In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.
Examples
A natural gas moisture detection device, as shown in figure 1, comprises a detection unit, a balance unit 4 and a support unit 6;
the detection unit is connected with the balance unit 4 through a connecting wire 5, the detection unit is arranged at the left end of the balance unit 4, the balance unit 4 is arranged at the right end of the supporting unit 6,
when the detection unit does not detect the natural gas or/and does not detect the presence of moisture in the natural gas, the detection unit and the balancing unit 4 are relatively static;
when the detection unit detects the presence of moisture in the natural gas, the detection unit and the balancing unit 4 move relatively.
When the method is implemented, the method comprises the following steps: when natural gas detection is not performed, the weight of the balancing unit 4 should be consistent with that of the detection unit to ensure that the balancing unit 4 and the detection unit can keep a relatively static state, so that a balanced system is constructed by the detection unit and the balancing unit 4. When natural gas moisture detection is performed, if moisture exists in natural gas and the weight of the detection unit is increased, the balance system constructed by the detection unit and the balance unit 4 is broken, so that relative motion occurs between the detection unit and the balance unit 4, namely: the detection unit moves downwards, the balance unit 4 moves upwards, and whether moisture exists in the detected natural gas or not can be reflected visually through the motion states of the detection unit and the balance unit 4.
Specifically, in the present embodiment, the supporting unit 6 is provided as a fixed pulley, and the fixed pulley is fixedly provided on the top of the wall; the detection unit and the balance unit 4 are connected through a connecting wire 5, the connecting wire 5 is hung on the fixed pulley, so that the detection unit and the balance unit 4 are respectively positioned at the left side and the right side of the fixed pulley, the weight of the detection unit and the weight of the balance unit 4 are equal through adjusting the weight of the balance device, and the detection unit and the balance unit 4 are relatively static; the balance device in the embodiment is arranged as a cabin body with a hollow inner part, and the weight of the balance device can be adjusted to be matched with the weight of the detection unit by adding or reducing a heavy object into the cabin body; the detection unit in the embodiment is set as a detection cabin 1, an air inlet pipe 2 is fixedly arranged on the detection cabin 1, a valve 3 (an electric valve or an electromagnetic valve) is arranged on the air inlet pipe 2, and a drying agent 7 is filled in the detection cabin 1; when the valve 3 is opened, natural gas enters the detection chamber 1, and if moisture exists in the natural gas, the equilibrium state of the detection unit and the equilibrium unit 4 is broken, so that relative movement occurs. In order to make the natural gas can be smooth to enter into the detection cabin 1, and the natural gas that gets into in the detection cabin 1 can not be wasted, as preferred, can also set up the branch road of giving vent to anger on the detection cabin 1, equally, the branch road of giving vent to anger includes valve 3 (motorised valve or solenoid valve) and outlet duct 12, after natural gas passes through intake pipe 2 and gets into the detection cabin 1, can get rid of from outlet duct 12, through being connected to suitable storage storehouse with the branch road of giving vent to anger, can collect the natural gas, avoid causing the phenomenon that the staff is poisoned because of the natural gas leaks.
Further, in order to timely turn off the valve 3 on the intake branch when moisture is detected in the natural gas, the balancing unit 4 in this embodiment is further provided with a power supply and a conductive column 8, the power supply is disposed inside the balancing unit 4, one end of the conductive column 8 is electrically connected to the power supply, and the other end is exposed out of the balancing unit 4; a limiting groove 9 is formed in the detection cabin 1 along the height direction, a first conductive interface 10 is arranged on one side, close to the bottom of the detection cabin 1, of the limiting groove 9, and the first conductive interface 10 is electrically connected with a solenoid valve on the air inlet branch and a solenoid valve on the air outlet branch;
when the detection unit and the balancing unit 4 are relatively stationary, i.e.: when the natural gas does not contain moisture in an initial state (a non-working state), the conductive column 8 is positioned in the first conductive interface 10, electromagnetic valves of the air inlet branch and the air outlet branch are communicated with a power supply at the moment, the electromagnetic valves are in an open state, and the natural gas can enter the detection cabin 1 through the air inlet branch and flow out of the air outlet branch; when the detecting unit and the balancing unit 4 move relatively, namely: when moisture exists in the natural gas, the conductive column 8 moves upwards along with the balance unit 4, so that the conductive column 8 is separated from the first conductive interface 10, electromagnetic valves of the air inlet branch and the air outlet branch are not communicated with the power supply, the electromagnetic valves are in a closed state, and the natural gas does not enter the detection cabin 1 any more; meanwhile, the electromagnetic valves of the air inlet branch and the air outlet branch are both in a closed state, so that moisture in the air can not enter the detection cabin 1 through the air inlet branch or the air outlet branch.
It should be noted that, in order to avoid that the power supply is still in an operating state when the detection device is in an inoperative state, that is: the power supply supplies power to the electromagnetic valve; when the detection device does not work, the weight in the balance detection unit can be reduced, so that the detection unit and the balance unit 4 are not at the same height, and the conductive column 8 is not located in the first conductive interface 10.
Further, in order to inform that moisture exists in the natural gas of staff in time, still be provided with the alarm in this embodiment, when the detecting element detects that the natural gas exists moisture, the alarm reports to the police.
