The internal structure of traditional water meters can be divided into three parts: shell, sleeve, and inner core from the outside to the inside. The shell is made of cast iron, and after water comes out of the inlet, it passes through the lower annular space of the shell, which is called the "lower annular chamber". Above this circular space, there is an "upper chamber" connected to the water outlet. There is a filter with a small hole at the bottom of the sleeve, which filters out impurities in the water. There are two rows of circular holes on the side of the sleeve, located exactly opposite the upper and lower ring chambers of the shell. Obviously, the lower row is the inlet hole and the upper row is the outlet hole. It is particularly noteworthy that both rows of holes are drilled diagonally along the tangent direction of the circle. Note that the directions of the upper and lower rows of holes are opposite. Water flows in along the tangent direction from the lower drainage hole, inevitably forming a rotating water flow, which is very important for the operation of the water meter. The inner core is divided into three layers: upper, middle, and lower. From the glass window, the upper layer is visible, with only the pointer and dial. The most crucial thing is actually the lower layer, which has a plastic wheel with many plastic blades on the edge, called the "impeller".

Intelligent IC card water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and intelligent IC card technology to measure water consumption, transmit water data, and settle transactions. This is a significant improvement compared to traditional water meters that generally only have the functions of flow collection and mechanical pointer display of water consumption. The intelligent IC card water meter can not only record and electronically display water consumption, but also automatically control water consumption according to agreements, and automatically calculate water fees for tiered water prices. At the same time, it can also store water usage data. Due to its data transmission and transaction settlement being carried out through IC cards, it is possible to achieve a transformation from on-site meter reading and charging by staff to users paying fees at their own offices. 

Ductile iron manhole cover is a type of ductile iron product. Ductile iron obtains spherical graphite through spheroidization and inoculation treatment, effectively improving the mechanical properties of cast iron, especially improving plasticity and toughness, resulting in higher strength than carbon steel. Ductile iron is a high-strength cast iron material developed in the 1950s, with comprehensive properties similar to steel. Based on its excellent performance, it has been successfully used to cast some parts with complex stress, high requirements for strength, toughness, and wear resistance. Ductile iron has rapidly developed into a widely used cast iron material, second only to gray iron. The so-called "replacing steel with iron" mainly refers to ductile iron.

Gully Grates are used to cover roads or deep wells in homes to prevent people or objects from falling. According to material, it can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc.

Fasteners are a type of mechanical component widely used for fastening connections. Fasteners are widely used in various industries, including energy, electronics, electrical appliances, machinery, chemical, metallurgy, molds, hydraulic, and more. They can be seen in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments, and supplies. They are the most widely used mechanical basic components. Its characteristics are a wide variety of specifications, diverse performance and uses, and a high degree of standardization, serialization, and generalization. Therefore, some people also refer to a type of fastener that already has national standards as standard fasteners, or simply standard components.

Couplings, also known as couplings. A mechanical component used to firmly connect the active and driven shafts in different mechanisms and rotate them together, transmitting motion and torque. Sometimes it is also used to connect a shaft with other parts (such as gears, pulleys, etc.). It is often composed of two halves, which are connected by keys or tight fits, fastened at the ends of the two shafts, and then connected together in some way. Couplings can also compensate for the displacement (including axial displacement, radial displacement, angular displacement, or comprehensive displacement) between two shafts due to inaccurate manufacturing and installation, deformation during operation, or thermal expansion; And mitigate impact and absorb vibration.

316 stainless steel has good oxidation resistance in intermittent use below 1600 degrees and continuous use below 1700 degrees. It is best not to continuously use 316 stainless steel within the temperature range of 800-1575 degrees, but when using 316 stainless steel continuously outside this temperature range, it has good heat resistance. The resistance to carbide precipitation of 316L stainless steel is better than that of 316 stainless steel, and can be used within the above temperature range. 316 has better corrosion resistance than 304 stainless steel, and has good corrosion resistance in the production process of pulp and paper. Moreover, 316 stainless steel is resistant to marine and corrosive industrial atmospheres.

Stainless steel bars are made from stainless steel ingots, which are hot-rolled or forged.
According to shape, it can be roughly divided into stainless steel round rods, stainless steel square rods, and stainless steel hexagonal rods.
According to surface treatment, it can be divided into: stainless steel black rod, stainless steel acid white rod, stainless steel bright rod, and stainless steel grinding rod.

Submersible pumps are important equipment for deep well water extraction. When in use, the entire unit works by diving into the water and extracting groundwater to the surface. It is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship load adjustment, and can also be used for fountain landscapes.
The hot water submersible pump is used for hot spring bathing, and can also be used to extract groundwater from deep wells. It can also be used for water extraction projects such as rivers, reservoirs, and channels. Mainly used for irrigation in farmland and water for human and livestock in high-altitude areas, it can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage.

Ductile iron manhole covers are a measure used to cover the wellhead, usually used on roads, parking lots or other public areas. Ductile iron manhole cover is made of ductile iron material, which is characterized by strong and durable, excellent compression performance, anti-slip, anti-theft, anti-noise, fire and so on.
Nodular cast iron is a kind of material composed of cast iron and alloying elements such as nickel and palladium. After spheroidization, it forms a kind of cast iron with high strength and corrosion resistance. Ductile iron manhole cover has high strength and durability, can withstand a lot of pressure and weight, to prevent the material in the well overflow or cause ground collapse.
