　　水(shui)(shui)(shui)(shui)(shui)(shui)(shui)表(biao)(biao)是一(yi)種普遍使用的(de)計量設(she)備，用于監(jian)測(ce)自(zi)來水(shui)(shui)(shui)(shui)(shui)(shui)(shui)、污(wu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)、工業廢水(shui)(shui)(shui)(shui)(shui)(shui)(shui)、汽(qi)車(che)冷(leng)卻(que)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)等管道(dao)輸送中(zhong)的(de)流量。水(shui)(shui)(shui)(shui)(shui)(shui)(shui)表(biao)(biao)外殼是水(shui)(shui)(shui)(shui)(shui)(shui)(shui)表(biao)(biao)的(de)主要結(jie)構部件(jian)，可以把水(shui)(shui)(shui)(shui)(shui)(shui)(shui)表(biao)(biao)分(fen)為兩大(da)類(lei)：一(yi)類(lei)是全封(feng)(feng)(feng)閉(bi)式(shi)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)表(biao)(biao)，其(qi)外殼中(zhong)有(you)(you)密封(feng)(feng)(feng)膠密封(feng)(feng)(feng)，不會引起水(shui)(shui)(shui)(shui)(shui)(shui)(shui)霧腐蝕，而結(jie)構簡單，成本較低，適(shi)用于普通自(zi)來水(shui)(shui)(shui)(shui)(shui)(shui)(shui)管道(dao)監(jian)測(ce)；另(ling)一(yi)類(lei)是半封(feng)(feng)(feng)閉(bi)式(shi)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)表(biao)(biao)，其(qi)外殼需要配合工業氣體進行加(jia)壓封(feng)(feng)(feng)閉(bi)，適(shi)用于監(jian)測(ce)含有(you)(you)顆粒、水(shui)(shui)(shui)(shui)(shui)(shui)(shui)霧、有(you)(you)害氣體的(de)工業廢水(shui)(shui)(shui)(shui)(shui)(shui)(shui)、污(wu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)、汽(qi)車(che)冷(leng)卻(que)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)等管道(dao)。

　　無論是全封閉式水表還是半封閉式水表的外殼，其材料都可以根據水質的不同而選擇，一般來說，如果水質較差，外殼材料應該選擇鋼板，如果水質較好，外殼材料應該選擇不銹鋼。半封閉式水表外殼的典型材料是鋼板加工成(cheng)的，而其(qi)制造(zao)工藝也(ye)比較簡單(dan)。但是半封(feng)閉(bi)式(shi)水(shui)(shui)表外殼需要進(jin)行(xing)壓力封(feng)閉(bi)，否則水(shui)(shui)霧和氣體會導致(zhi)內部部件的腐蝕，使水(shui)(shui)表的使用壽命大(da)(da)大(da)(da)縮短。

　　對于水表外殼加工工(gong)藝，根據水表的不同類型和使(shi)用要(yao)求，可以采用不同的工(gong)藝方法(fa)，進行水表外(wai)殼(ke)的加(jia)工(gong)。如果要(yao)制造一(yi)(yi)個全封閉式水表外(wai)殼(ke)，可以采用鈑金加(jia)工(gong)、沖壓加(jia)工(gong)等方法(fa)；如果要(yao)制造一(yi)(yi)個半封閉式水表外(wai)殼(ke)，可以采用鍛(duan)造或(huo)鍛(duan)壓加(jia)工(gong)方法(fa)；如果要(yao)制造一(yi)(yi)個普(pu)通水表外(wai)殼(ke)，則可以采用注塑或(huo)鑄(zhu)造加(jia)工(gong)方法(fa)。

　　目(mu)前市場上使用(yong)最廣(guang)泛的(de)(de)水表(biao)外殼(ke)(ke)加(jia)(jia)工(gong)方法是鈑金加(jia)(jia)工(gong)。鈑金加(jia)(jia)工(gong)又稱為(wei)沖(chong)(chong)壓加(jia)(jia)工(gong)，是一種(zhong)采(cai)用(yong)沖(chong)(chong)床或其他(ta)(ta)機床將工(gong)件的(de)(de)表(biao)面壓到所需形狀的(de)(de)加(jia)(jia)工(gong)方法。鈑金加(jia)(jia)工(gong)相對于(yu)其他(ta)(ta)加(jia)(jia)工(gong)方法來說(shuo)，具有成本低(di)、速度(du)快、工(gong)藝簡(jian)單的(de)(de)優點。一般來說(shuo)，采(cai)用(yong)鈑金加(jia)(jia)工(gong)制造水表(biao)外殼(ke)(ke)的(de)(de)成本大約是其他(ta)(ta)加(jia)(jia)工(gong)方法的(de)(de)一半。因此，鈑金加(jia)(jia)工(gong)是制造水表(biao)外殼(ke)(ke)的(de)(de)首選方法。

　　中國現在發展迅速，水表制造業也在不斷發展壯大，水表廠家想要(yao)在市場(chang)上(shang)占據一席之地(di)，就必(bi)須不斷提(ti)(ti)高產品質量，提(ti)(ti)高水表外殼(ke)加工水平(ping)。

　　Water meters are a commonly used measuring device to monitor the flow of water, wastewater, industrial wastewater, automotive cooling water and other pipeline transmission. The water meter shell is the main structural component of the water meter, which can be divided into two categories: one is the fully sealed water meter, which has sealing glue sealing in the shell, will not cause water mist corrosion, and the structure is simple, the cost is low, suitable for ordinary water pipeline monitoring; The other is a semi-closed water meter, which requires pressure sealing with industrial gas in the shell, and is suitable for monitoring industrial wastewater, sewage, automotive cooling water and other pipelines with particles, water mist, harmful gases.

　　Whether it is a fully sealed water meter or a semi-closed water meter, the material of the shell can be selected according to the different water quality. Generally speaking, if the water quality is poor, the shell material should be steel plate, and if the water quality is good, the shell material should be stainless steel. The typical material of the semi-closed water meter shell is processed by steel plate, and the manufacturing process is also relatively simple. However, the semi-closed water meter shell needs to be sealed under pressure, otherwise the water mist and gas will cause corrosion of the internal components and greatly shorten the service life of the water meter.

　　For water meter shell processing technology, according to the different types of water meters and use requirements, different processing methods can be used for water meter shell processing. If you want to manufacture a fully sealed water meter shell, you can use sheet metal processing, stamping processing, etc.; if you want to manufacture a semi-closed water meter shell, you can use forging or forging processing; if you want to manufacture an ordinary water meter shell, you can use injection molding or casting processing.

　　The most widely used processing method for water meter housings on the market is sheet metal processing. Sheet metal processing is also called stamping processing, which is a processing method that uses press or other machine tools to press the surface of the workpiece into the required shape. Sheet metal processing has the advantages of low cost, fast speed and simple process compared with other processing methods. Generally speaking, the cost of manufacturing water meter housings by sheet metal processing is about half of that of other processing methods. Therefore, sheet metal processing is the first choice for manufacturing water meter housings.

　　Now China is developing rapidly, the water meter manufacturing industry is also growing rapidly, water meter manufacturers want to occupy a place in the market, we must continuously improve product quality, improve water meter shell processing level.
