| titleOfInvention | Supercharging device for water meter detection |
| abstract | The utility model provides a supercharging device for water meter detection, which comprises a supercharging cylinder and a three-position four-way hand-operated valve, wherein the three-position four-way hand-operated valve comprises a first port, a second port, a third port and a fourth port; the first port is communicated with a system water inlet port through a pipeline, the second port is communicated with a water discharge port through a pipeline, the third port is communicated with a pressurization port, the fourth port is communicated with a pressure relief port, the pressurization cylinder comprises a first cylinder body and a second cylinder body which are communicated, the inner diameter of the second cylinder body is smaller than that of the first cylinder body, and a pressure detection element is arranged on a communication pipeline between a water outlet port of the second cylinder body and a water inlet port of a water meter to be detected; the water circulating in the pipeline is utilized, better pressurization and pressure maintaining effects are realized through gating of the three-position four-way hand-operated rotary valve and a unique booster pump design, and the good pressurization and pressure maintaining effects can still be realized through manual control when abnormity occurs in electric switching. |
