Problems solved by technology

In the past, to solve the problem of "water meter idling", the first step is to open all the faucets in the user's house to remove the air in the faucet; then check whether there is any water leakage in the indoor pipes, especially the toilet, shower, etc. However, the problem is still not solved at this time

Embodiment 1

[0022] Embodiment 1 A water meter vacuum device

[0023] Such as Figure 1-2 As shown, a water meter vacuum pumping device in this embodiment includes a water tank 1, a water pump 2, a No. 1 solenoid valve 3, a No. 2 solenoid valve 4, a No. 3 solenoid valve 5, a No. 4 solenoid valve 6, and a No. 5 solenoid valve. 7. Booster pump 8, water meter 9, water inlet locking device 10, water outlet locking device 11, vacuum source 12, console 13, the water meter is connected in series between the water inlet locking device and the water outlet locking device, through The water inlet locking device and the water outlet locking device lock the water meter; the water tank 1 is connected to the water pump 2 and the vacuum source 12 respectively, and the water pump and the water inlet locking device are connected to each other through the pipeline A14, and the pipeline A No. 2 solenoid valve is set on the top; the pipe A is connected to the pipe B at the position between the No. 2 solenoid...

Embodiment 2

[0024] Embodiment 2 A method for ensuring the detection performance of a water meter

[0025] Such as figure 1 and 2 As shown, the method for guaranteeing the detection performance of the water meter of the present invention adopts the water meter vacuumizing device in Embodiment 1, and then adopts the following steps:

[0026] S1) The water meter locks the water meter through the water inlet locking device and the water outlet locking device;

[0027] S2) closing No. 2 solenoid valve and No. 3 solenoid valve through the console;

[0028] S3) Open the No. 1 solenoid valve and fill the water meter with water through the booster pump;

[0029] S4) Let the water flow back to the water tank by opening the No. 4 solenoid valve, and open the No. 5 solenoid valve at the same time. The water pump outputs a higher pressure, and the pressure of the water pump is higher than that of the booster pump. It returns to the water tank through the vacuum source, and a vacuum is formed at thi...

Abstract

The invention discloses a water meter vacuumizing device and a method for guaranteeing the detection performance of a water meter. The water meter vacuumizing device comprises a water tank, a water pump, a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve, a fourth electromagnetic valve, a fifth electromagnetic valve, a booster pump, a water meter, a waterinlet locking device, a water outlet locking device, a vacuum source and a console. The water meter is connected between the water inlet locking device and the water outlet locking device in series. By means of the water meter vacuumizing device, air in a water meter can be completely pumped out, and the detection performance of the water meter is guaranteed. In addition, the invention further provides the method capable of guaranteeing the detection performance of the water meter; air in a water meter can be completely pumped out through the method for guaranteeing the detection performance of the water meter, and therefore the detection performance of the water meter is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of water equipment, and in particular relates to a water meter vacuum device and a method for ensuring the detection performance of the water meter. Background technique [0002] In our life, sometimes this phenomenon occurs: the phenomenon of "water meter idling" without using a water meter. This is due to the pressure of the pipeline mixed with air and the change of water temperature. There is air in the water pipe, and the pulsation effect produced by it makes the water meter installed in some places slow down when there is no water flowing, and the numbers are often cumulative. of. In the past, to solve the problem of "water meter idling", first open all the faucets in the user's house to remove the air in the faucets; then check whether there is any water leakage in the indoor pipes, especially the toilet, shower, etc. However, the problem still cannot be solved at this time.
