The following detailed description of the embodiments of the present invention is provided in order to make the technical solution of the present invention easier to understand and understand.

Example (b):

the embodiment provides a sealing test supercharging system, mainly used solves the unable continuous relapse of water supply going on of water gauge verification in-process to and the problem that the air influences the verification result appears easily.

Referring to fig. 1 to 4, in the process of water meter verification, reading verification needs to be performed on a water meter through water input, and further, it is needed to avoid an influence on a verification result due to mixing of air, most of existing pressurization systems cannot guarantee continuous and uninterrupted water supply, so that verification efficiency is affected, and meanwhile, a problem that air may enter is caused, in this embodiment, a seal test pressurization system includes a water conveying pipeline 11, one end of the water conveying pipeline 11 is used for water inlet, the other end of the water conveying pipeline 11 is used for installing a water meter, two check valves 3 arranged at intervals are arranged on the water conveying pipeline 11, the water conveying pipeline 11 is located between the two check valves 3 to form a pressurization pipe section 111, and the pressurization pipe section 111 is provided with a pressurization member for pressurizing water flowing in the pressurization pipe section 111; the purpose of pressurizing the inside of the pressurizing pipe section can be achieved through the pressurizing part, the purpose of reciprocating water supply in the water meter verification process can be guaranteed through the water conveying pipeline, the purpose that water cannot flow backwards in the water conveying pipeline is guaranteed through the arrangement of the one-way valve, the problem that air enters into the follow-up verification step can be solved, the purpose of effectively verifying the inside of the water meter is achieved, and the purpose of effectively supplying water to the water meter pipeline is achieved.

The specific embodiment of the above-mentioned influent water is; one of the inlet tube is provided with a water pump, water can be timely conveyed into the water conveying pipeline through the water pump, and then enters the pressurizing pipe section through the one-way valve.

Through the arrangement of the one-way valve 3, the situation that water flows backwards in the water inlet pipe 2 and the water outlet pipe 4 can be avoided, so that the water supply process is influenced, and the subsequent verification process can be influenced;

the water flow directions of the check valves 3 are consistent, and the water flows into the water conveying pipeline from the water inlet pipe and further flows into the water outlet pipeline.

Meanwhile, the one-way valve 3 is connected in one section of the water inlet pipe 2 and the water outlet pipe 4 through threads; the above arrangement can ensure that the water inlet pipe 2 and the water outlet pipe 4 are easier to disassemble and replace, and meanwhile, the flexibility and convenience of the whole device are ensured.

As described with reference to fig. 1, fig. 3 and fig. 4, since the water in the water inlet pipe 2 needs to be conveyed into the water conveying pipeline, and a closed space is needed to improve the pressurizing environment, in order to solve such problems, the pressurizing member includes a pressurizing pipe arranged on the pressurizing pipe section 111 and communicated with the pressurizing pipe section 111, and a pressurizing cylinder 1, wherein a piston rod 12 of the pressurizing cylinder 1 is arranged in the pressurizing pipe in a penetrating manner and coaxial with the pressurizing pipe, and is used for squeezing the water flow in the pressurizing pipe; when water flows into the water conveying pipeline, the pressurizing piece starts to operate at the moment, so that the piston rod 12 starts to move, the air pressure in the pressurizing pipe is ensured to be continuously raised, and the water in the water inlet pipe is further ensured to be pushed into the water outlet pipe.

It should be noted that, due to the action of the check valve, the effect in the pressure-increasing pipe is more sufficient, and the water delivery is more rapid.
