How to disassemble the water meter

Question 1: How to disassemble the water meter and take out the core? If it is a mechanical water meter or a domestic water meter with a diameter of 15, you have to unscrew the copper cover of the water meter counterclockwise with a tongs. If it is an IC card water meter, you can unscrew the screw at the bottom of the water meter, but the movement should be sealed and driven by magnetic force. I'm from the water company.

Question 2: How to change the water meter? . It won't fall off. . How to open it? Call the water company, and they will send someone to open it. We can't tear it down ourselves. We use pipe tongs to dismantle it here.

Question 3: How to disassemble the water meter depends on how big your water meter is. Usually, DN 15-DN40 water meters are connected by threads. Just unscrew two sets on the water meter! Remember that there is an eraser between the water meter and the thread. All water meters above DN50 are flanged. You can remove it by unscrewing the screws on the flange, and there is a rubber in the middle.

Question 4: How to turn off the water meter with the big adjustable wrench! As for the demolition, you can also use adjustable wrench!

Question 5: How to disassemble the installed water meter? How to disassemble the installed water meter? Cut off the lead seal on the water meter and open the copper seal with a pipe wrench. Replace it with a new one (don't forget the sealing ring) and reinstall the sealing cover with a pipe wrench.

An instrument for measuring water flow. Most of them are cumulative flow measurement of water. Generally divided into two types: volumetric water meter and speed water meter. The former has higher precision than the latter, but it requires high water quality and is easy to block when water contains impurities. An instrument for recording the water consumption of tap water is installed on the water pipe. When the user discharges water, the pointer or character wheel on the water meter rotates to indicate the amount of water passing through.

Installation method of water meter:

1, the diameter of the water meter should be determined according to the diameter of the installation pipeline, and the installation position should avoid exposure to sunlight, immersion, freezing and pollution, which is convenient for disassembly and swiping.

2. The water meter should be installed horizontally (with the display facing up).

3. Before the installation of new clothes, sand, hemp and other sundries in the pipeline should be removed to avoid water meter failure.

4. The arrow direction displayed by the water meter should be consistent with the direction of water flow in the pipeline.

5. If the water meter is installed at the inlet end of the boiler, it is best to install a check valve at the outlet of the water meter to prevent the boiler hot water and steam from flowing back and damaging the internal parts of the water meter.

Question 6: How to turn on the old water meter? This is a mechanical water meter. The following are the methods of meter reading: 1. Identify the dial. At present, mechanical water meters used at home generally have eight dials. The four red indicators on the right: ×0. 1, × 0.0 1 ... are all less than 1 m3 because of tap water. Generally, these dials have no practical guiding significance and do not need to be seen. The four black hands on the left indicate that the dial × 1 and × 10 ... are the basis of tap water metering and charging, LZ should learn to understand. Second, recognize the pointer. Four black hands indicate that the dial is counterclockwise from top to bottom, namely one needle (× 1), ten needles (× 10), hundreds of needles (× 100) and thousands of needles (× 1000). The pointer of × 10 turns once, and the pointer of × 100 goes one word; The pointer of × 100 turns once, and the pointer of × 1000 goes one word. Third, the essentials of reading. When reading the water meter, you should read it from the high pointer to the low pointer in turn, that is, read it clockwise from bottom to top based on the indicated value of the pointer × 1000. It is important to pay special attention to: if the position of thousands, hundreds and tens pointers is between two numbers, we should pay attention to the association between the upper and lower adjacent pointers. Generally speaking, you should take a smaller one. If the pointer is 0-, the LZ water meter can be read according to the meter reading method.

Generally, you only look at the black table number, which is the whole tonnage, and the red table number is the tonnage after the decimal point. X 1000 stands for thousands. The number of the black table x 1000 is 0, so this is not read. X 100 represents the hundredth digit of a number. The number of black table x 100 is 6, so the percentile of this study is 6. X 1 represents the ten digits of a number. The number of black table x 10 is 9, so the decimal number of this reading is 9. X 1 a single digit representing a number. The number on the black watch is 9, so the single digit of this reading is 9. Since the reading is 0 in one thousand (not read), 6 in one hundred, 9 in ten and 9 in one, the water meter reading is 699, and * * * used 699 tons of water.

Question 7: How to remove and replace the valve in front of the water meter? First, close the main valve, loosen the screws at both ends of the valve, pay attention to the gasket when replacing it, be sure to install it, and open the main valve to see if there is any leakage.

Question 8: How to remove the water meter connector? Most people have water meters. Many times the water meter is broken, which will affect the domestic water consumption. How to disassemble the water meter? This is a simple lesson for you!

1, close the main stop valve (valve). If the water pipe entering the house is directly connected to the water meter, the outdoor main intercepting door should be closed.

2. Remove the big screw with a wrench and remove the water meter.

3. Wrap the thread of the iron pipe prepared before with the raw material belt.

4. Install the iron pipe in the original position of the water meter with the help of pipe tongs and wrenches.

5. Just open the main gate (valve).
