Zinc or Nickel Plating Production Line
Metal electroplating line is widely used in aircraft and auto parts, machinery parts, metal, hardware processing industries, including cooper plating, silver plating, zinc plating, nickel plating, gold plating, chrom plating, anodizing, electrophoresis production line,etc.
Zinc-nickel alloy is an anti-corrosion coating with excellent corrosion resistance. At the same time, it has good mechanical properties and does not change the mechanical properties of the steel after plating. It has excellent brazing properties and is easy to weld under various conditions. The internal stress of the coating is small, which is comparable to that of the cadmium coating in the torsion-tension test. The plating solution has good dispersing ability and covering ability, high current efficiency, bright and smooth coating.
The surface condition and processing requirements during electroplating, select the appropriate steps, and perform the necessary finishing processing on the surface of the part, so that the part has a smooth and clean surface, which is an important link in obtaining a high-quality coating.

Summary of the Invention The utility model relates to the field of water meters, in particular to a valve-controlled pre-paid remote-displacement type water meter. The utility model comprises a volumetric water meter which is fixedly connected to a control valve through a connecting pipe and a nut. The control valve is controlled by a data transmission line. One end of the data transmission line is connected to a positive displacement water meter, and the other end is connected. On the control valve. The utility model is transmitted to a computer through a measurement data transmission line to realize a prepayment function and solve the problem of user arrears. 
BACKGROUND OF THE INVENTION Existing installations in pipelines consist of a number of chambers of known volume that are successively filled and discharged with fluids, and a water meter consisting of a fluid-driven mechanism, or simply a metered-discharge type water meter.
The piston inside the volumetric water meter causes the piston to generate a rotational torque under the differential pressure of the fluid. With the rotation of the piston, the fluid flows from the inflow port to the outflow port, at which time the piston rotates eccentrically. By measuring the number of revolutions of the piston, the flow rate of the fluid can be determined. Therefore, the volumetric water meter has the advantages of high measurement accuracy and high sensitivity compared to other types of water meters. However, most of the market's volumetric water meters are mechanical readings, as the volumetric water meters are mainly exported abroad, and are installed in underground manhole covers abroad. This causes troubles such as meter reading, meter reading, and many other shortcomings. According to market feedback, foreign users also have water. The situation of arrears, and the water meter in the case of arrears, there is no good way to enable users to pay water fees in a timely manner.
The technical principle addresses the deficiencies in the prior art. The utility model provides a valve-controlled pre-paid remote transmission type water meter to solve the problem of inconvenient meter payment and user arrears.
Technically speaking, this type of valve-controlled pre-paid remote transmission type water meter, including volumetric water meter water consumption, passes through the data transmission line to the control valve module. When the amount of water shortage reaches the preset shortage, the user is reminded to pay the fee. When the dosage is zero, the valve is closed and the module is wirelessly transmitted to the collector. The collector is then transmitted to the concentrator. The concentrator is then transmitted to the computer. The balance of how much water is opened and closed in all tables can be reflected in the computer. .
The bottom of the control valve is provided with a battery base, and the base is provided with an external thread. The threaded connection meets strength requirements and is easy to implement. When replacing the battery, only the battery cover can be opened by hand, and the battery can be replaced to greatly increase the service life of the entire watch. Save water company's use cost.
Compared with the prior art, the measurement data transmission line is transmitted to the computer to realize the prepayment function and solve the problem of user arrears.
The patent application company Ningbo Jingcheng Technology Co., Ltd. is a domestic company with a higher level of knowledge in the field of smart valve-controlled remote water meters. It has covered 28 provinces and municipalities directly under the Central Government in China and has been exported to Southeast Asia, South America, Europe, and Africa.
