- Q: What is the nominal flow of water meters?
- (1) the nominal flow rate of DN15 is 1.5 m3/h;(2) the nominal flow rate of DN20 is 2.5 m3/h;(3) the nominal flow rate of DN25 is 3.5 m3/h.Some water meters on the subject of "N2.5" refers to the "water meter nominal flow Qn is 2.5 m3/h", from which we can know that the water gauge's caliber is DN20. (nominal flow, some people are accustomed to commonly known as flow)
- Q: Water leakage or water meter bad at home, regardless of how to do?
- If the owners Water Leakage inside their own Water Leakage, or Water Leakage upstairs, the owners should repair or maintenance of the owners upstairsThe classification of this situation:(a) if the warranty period, the developer should be responsible for maintenance;(two) if the warranty period has passed, the owner shall maintain it by himself.
- Q: What is the rate of installation of water meters?
- A scale measuring rate of 100% two meter f (rate = two level table and a table of water / water) x100%.
- Q: My water meter in the absence of water, water meters on their own table?
- Installation method and installation quality3.1, because now the water meter out of households are mostly a unit of households, tables are concentrated in a box, installed on the first floor. Taking into account the freezing cold winter and the meter, with 6 or 12 meter with a diameter of 40mm- 50mm diameter pipe, tables and small spacing and straight sections set aside less water, this will also affect the normal water metering, causing water rotation.3.2, installation quality, pipeline projects are basically buried in the ground or in the wall, is a hidden project. National construction standard pipe provides various pipe pipeline construction installation requirements, construction process, acceptance criteria and matters needing attention, but in the construction site, some managers do not according to the requirements of the code construction, more or less there are some quality problems caused by pipeline.
- Q: What's wrong with Ann's new water meter? Can you get back after reinstalling?
- A water meter is an instrument for measuring water flow. The cumulative flow of water is mostly measured. Generally divided into the volume of water meters and speed water meter two categories. The accuracy of the former is higher than that of the latter, but it requires high water quality and is easily blocked when the water contains impurities. An instrument for recording the amount of water used in running water is mounted on a water pipe, and when the user leaves the water, the pointer or wheel turns on the table to indicate the amount of water passed.
- Q: What's wrong with a water meter with a flange connection?
- This connection is mainly used for cast iron pipes, non-ferrous metal pipes and flanges, valves, valves and other connections, process equipment and flange connections are also flange connection. The main feature of flange connection is convenient disassembly, high strength and good sealing performance. When installing flanges, the two flanges shall be kept parallel and the sealing surfaces of flanges shall not be damaged and shall be cleaned. Gaskets used for flanges shall be selected according to design requirements.
- Q: Problem of water meter joint
- If you twist it, twist it out of the linen or raw tape, if there is no hemp or raw tape
- Q: Copper valve, screw valve, copper lock valve difference, which should be in front of the water meter, which should be in the water meter after their role?
- Installed in water, is usually a locking valve installed in the water in the water in front of oneself, the common gate valve or ball valve installed in the water after, in order to form after failure to remove and close the valve without water and other operations.
- Q: What is a two meter water meter?
- The accuracy level of the water meter is divided into 1 grades and 2 grades.(1) the accuracy level 1 is only applicable to the common flow rate Q. More than 100m3 / h meter, accuracy grade 2 is applicable to all common flow Q. Value water meter.(2) for most water meters based on mechanical flow sensors, the accuracy level is 2.(3) in the national standard GB / T778.1 - 2007, the requirement of the accuracy grade 1 is not adopted.
- Q: Do you know the working principle of dry water meters?
- The water pushes the impeller (the impeller is provided with magnetic steel, the impeller rotates and drives the magnetic steel to rotate) - the magnetic steel on the impeller drives the magnetic steel of the wheel box through the magnetic force the gear system changes speed --- the wheel rotates.
