            山東遠傳水表繼電器的關鍵性能參數

            目前國內水表的電控閥門主要有球閥、陶瓷閥和膜片閥.球閥因要求的驅動力矩大,使用中因結垢或磨損,很容易出現漏水、開關失靈等問題,國內 智能水表采用此類閥門的較多,在使用中出現的問題最多.陶瓷閥的使用壽命長、開關可靠性高、壓損小,使用中不易結垢,因是專利產品,國內智能水表采用此閥門的制造商很少.膜片閥因成本高制造商使用的不多.智能水表閥門也是在使用中的一個至關重要的性能指標.

            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.

            由于管網水質的原因,對水表閥門的破壞比較嚴重,直接影響了水表的收費計量,電控閥門的選用必須壽命長、開關可靠性高、壓損小,使用中不易結垢,目前陶瓷閥為不錯選擇.

            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.

            電控閥門模塊的主芯片是收費基表數據采集、處理、顯示及保存的核心部件,也是水表的技術核心,顯示了該類水表的技術、質量水平.國內智能水表制造商大都根據自己的產品特點和自己的研發實力自行研制主芯片,主芯片的質量和技術參差不齊;也有采用了美國Ti公司的超大規模集成電路為主芯片,技術成熟,功能強大、穩定性能好,此技術在國內水表制造行業處于領先地位,由于此技術的采用,率先在國內行業推出了一卡帶五表產品,滿足了復式樓房多表安裝和一個業主有多套住房的需要一卡操作的需求,技術純熟領先

            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.goliathboards.com
