7. A water meter monitoring device control system as claimed in any one of claims 1 to 6, wherein: the using steps are as follows:
a: before the detection device is used, whether a main power supply, an equipment communication port, a water supply system and a gas circuit system of equipment are reliably connected or not is detected, under the condition that all valves are closed, a connector of one to-be-detected ultrasonic water meter is inserted into a water outlet pipe, the other connector of the ultrasonic water meter is inserted into a connecting pipe, the connector is ensured to be aligned with a fixing groove formed in a sealing ring during insertion, the remaining seven to-be-detected ultrasonic water meters are inserted into the connecting pipe in the same method, after all the ultrasonic water meters are installed, a cylinder is started, the cylinder pushes a push plate to enable a water inlet pipe to move rightwards, and the water inlet pipe is inserted into the connector of;
b: after the step A is completed, after the ultrasonic water meter is installed, because the connector is aligned with the fixed groove, if the ultrasonic water meter is tightly connected with the connecting pipe, the second sliding block is difficult to push by starting the electric push rod, if a gap is left between the ultrasonic water meter and the connecting pipe, the electric push rod is started, the second sliding block slightly slides at the moment, the extrusion is not tight at the moment, the electric push rod is automatically recovered after being powered off, meanwhile, the reset spring assists the second sliding block to return to the original position, the air cylinder is started through the control cabinet, the extrusion is carried out again, the steps are repeated after the extrusion is completed, and the tight connection between the ultrasonic water meter and the connecting pipe is;
c: after accomplishing step B, the sealing washer easily produces slight damage after using a period, and be difficult to in time discover, be provided with the film in the connecting pipe, the film is because hydraulic extrusion makes its inner wall of hugging closely at the connecting pipe, thereby block up the gap, the water pressure that the film bore can be guaranteed to improve by the supporting network that sets up on the film, and can be according to hydraulic difference, change the density of supporting network, if there is a small amount of water seepage still, meet water inflation rubber and absorb water behind the inflation and closely laminate together with the thread groove, avoid rivers to continue the seepage, after the detection is accomplished, when pulling down the ultrasonic water meter, can extract meeting water inflation rubber from the slot, the detector of being convenient for in time discovers the problem, in time change the sealing washer, and insert new water inflation rubber.
