Embodiment 1

[0029] A 3G network-based smart home long-distance transmission data acquisition system, the water meter data acquisition system can realize the meter reading work of water meters in a residential area or even multiple residential areas. The water meter data acquisition system includes water meter, MSP430F149 microprocessor, Si4432 module, concentrator and central processing unit. The water meters are installed in the homes of residents in the community, and each household has a water meter. Each water meter is equipped with a MSP430F149 microprocessor and Si4432 module. Each Si4432 module can be equipped with a concentrator, or multiple Si4432 modules can be equipped with a concentrator. Multiple concentrators correspond to one CPU.

[0030] The water meter includes a water meter body, which is connected with a water inlet pipe and an outlet pipe, and both the water inlet pipe and the water outlet pipe are tangent to the water meter body, and both the water inlet pipe and t...

Embodiment 2

[0037] On the basis of Embodiment 1, a ball head placement groove 59 is provided on the end surface of the plug assembly 53 close to the side of the water inlet channel 515, and a rubber ball head 52 is arranged in the ball head placement groove 59, and the rubber ball head 52 can rotate freely in the ball head placement groove 59; a fine-tuning spring 524 is also provided between the rubber ball head 52 and the bottom of the ball head placement groove 59, and the rubber ball head 52 can be adjusted according to the water inlet flow path The flatness and inclination of the end surface of the 515 end face are adaptively changed, so that the end face of the rubber ball head 52 is in full contact with the end face of the water inlet channel 515, and the sealing performance of the contact part is improved.

[0038] Preferably, a spherical water outlet 525 is provided at the end of the water inlet channel 515 close to the plug assembly 53 , and the radius of curvature of the spheric...

Embodiment 3

[0040] On the basis of Embodiment 1 or Embodiment 2, a damping hole 518 is provided inside the central core drainage hole 519, and the drainage aperture of the damping hole 518 is smaller than the aperture of the central core drainage hole 519, so the water pressure in the water inlet channel 515 is relatively high. hour, the water is discharged through the damping hole 518, and because the cross section of the damping hole 518 is smaller, the flow rate of the water discharged in the water inlet channel 515 is smaller, and the water pressure in the water inlet channel 515 increases faster, so it can Make the middle spool 58 and the outer spool 57 separate quickly at the discharge hole, improve and accelerate the pressure relief.
