Anti-slip water meter and working method thereof

Abstract

The invention provides an anti-slip water meter comprising a metering mechanism, wherein a first installation cavity and a second installation cavity are defined on the inner side wall of the water inlet pipe of the water meter; a first spring seat is installed at the contact of the second installation cavity and the inner wall of the water inlet pipe, a flow hole is defined in the middle of the first spring seat, a first spring is sleeved on the first spring seat, and a first valve core is sleeved out of the first spring; a sealing plate is arranged at the end of the first installation cavity; a third installation cavity is defined on the inner side wall of the water outlet pipe of the water meter; a second spring seat is installed at the end of the water outlet pipe; a second spring is sleeved on the second spring seat, and a second valve core is sleeved out of the second spring. At the same time, the invention also provides a working method of the above air-slip water meter. When the water supply is cut off, the water outlet of the water meter has a one-way water flow function to prevents the stored water from flowing back such that the water meter does not slip. Moreover, the expansion and contraction of the "compressed air" in the water pipe are also suppressed, and the measurement error caused by the slipping of the water meter is reduced.

Description

technical field [0001] The invention belongs to the technical field of liquid measurement, in particular to an anti-idling water meter and a working method thereof. Background technique [0002] At present, the water meter idling phenomenon of high-rise residential users is relatively prominent, and users pay tens or hundreds of tons of water bills out of thin air, which is very troublesome. When looking for leaks, it is necessary to remove the decorations such as the floor of the home, and then restore the decorations after the removal, which is not only laborious and laborious, but also a financial loss. The inaccurate measurement caused by the idling of the water meter has led to disputes over water charges, and the number of complaints from users to water supply companies has increased, resulting in disputes. After the media exposure, it brought a negative impact on the social image of the water supply enterprises, and also embarrassed the government supervision departm...

[0005] 2) In the water supply pipe network, it is caused by water heater, solar water heater hot water, and toilet water backflow

The tap water pollution and unhygienic caused by this backflow will affect the health of users, which is unacceptable to users.

[0006] 3) The water supply pressure is unstable, and the fluctuation of water supply pressure is the main reason for the idling of the water meter. Due to the high measurement sensitivity of the water meter, especially the secondary pressurized water supply of high-rise buildings, in the water supply pipeline, due to the relatively high pipeline pressure, the water shows a certain compressibility of

When the pressure fluctuates in the pipe network, the water volume expands and compresses. When the pressure rises, the water volume in the pipe behind the meter will be compressed due to the pressure rise. At this time, a small amount of water will pass through the water meter, resulting in Autorotation; when the pressure drops, the compressed water is released, and a small amount of water will also pass through the water meter. Therefore, as long as the water pressure fluctuates once, the water meter will idle once. Frequent water pressure fluctuations will cause the user's water meter to idle more times, and the measurement Large error in water consumption
