目前国内水表的电控阀门主要有球阀、陶瓷阀和膜片阀.球阀因要求的驱动力矩大,使用中因结垢或磨损,很容易出现漏水、开关失灵等问题,国内 智能水表采用此类阀门的较多,在使用中出现的问题最多.陶瓷阀的使用寿命长、开关可靠性高、压损小,使用中不易结垢,因是专利产品,国内智能水表采用此阀门的制造商很少.膜片阀因成本高制造商使用的不多.智能水表阀门也是在使用中的一个至关重要的性能指标.
At present, there are mainly ball valves, ceramic valves and diaphragm valves in domestic water meters. Ball valves are prone to water leakage and switch failure due to large driving moment and scaling or wear in use. There are more such valves used in domestic intelligent water meters, and most problems occur in use. Ceramic valves have long service life and switch. High reliability, low pressure loss, easy to scale in use, because it is a proprietary product, few domestic manufacturers use this valve for intelligent water meters. Diaphragm valves are seldom used by manufacturers because of high cost. Smart water meter valves are also a vital performance index in use.

由于管网水质的原因,对水表阀门的破坏比较严重,直接影响了水表的收费计量,电控阀门的选用必须寿命长、开关可靠性高、压损小,使用中不易结垢,目前陶瓷阀为不错选择.
Because of the water quality of the pipeline network, the damage to the water meter valve is serious, which directly affects the charging and metering of the water meter. The selection of the electronic control valve must have long service life, high reliability of the switch, low pressure loss and easy to scale in use. At present, the ceramic valve is a good choice.
电控阀门模块的主芯片是收费基表数据采集、处理、显示及保存的核心部件,也是水表的技术核心,显示了该类水表的技术、质量水平.国内智能水表制造商大都根据自己的产品特点和自己的研发实力自行研制主芯片,主芯片的质量和技术参差不齐;也有采用了美国Ti公司的超大规模集成电路为主芯片,技术成熟,功能强大、稳定性能好,此技术在国内水表制造行业处于领先地位,由于此技术的采用,率先在国内行业推出了一卡带五表产品,满足了复式楼房多表安装和一个业主有多套住房的需要一卡操作的需求,技术纯熟领先
The main chip of the electronic control valve module is the core component of data acquisition, processing, display and preservation of the toll base meter, and also the technical core of the water meter. It shows the technology and quality level of this kind of water meter. Most domestic intelligent water meter manufacturers develop the main chip according to their own product characteristics and R&D strength, and the quality of the main chip. The technology differs from each other; Ti company's VLSI chip is also used as the main chip, which has mature technology, powerful function and good stability. This technology is in the leading position in the domestic water meter manufacturing industry. Because of the adoption of this technology, it is the first to introduce a five-meter card product in the domestic industry, which meets the multi-meter safety requirements of double-type buildings. Installation and multiple housing units of one owner require card operation, skilled and advanced technology.http://www.sdlyxqyb.com
