Its series of products are widely applied to such industries as petroleum , chemical engineering , metallurgy , electrical power , fertilizer , pharmacy , food, city construction and sewage treatment etc.
      The company covers an area of over 85000 m 2 , and has total staff members of over 580, among which 110 staffs are engineers & technicians , as well as over 250 sets of machining and testing equipments in different types. The group company has been granted the approval of second quality system of the IS09001:2000 , the NACE standard, National Association of Corrosion Engineers (USA), member of China Environmental Protection Association of valve, pump, sulphuric acid and phosphate fertilizer , member factory of the resource market of China P etrochemistry Supplies Equipment Company, network member of the 1st grade supplier of the stock and spare parts for r efining and c hemicals of China Petroleum & N atural G as Group, the AAA-grade enterprise with good credit, import & export enterprise with more freedom and high-tech enterprise in Shanghai. In the company, there are section offices such as technical department , quality inspection department , marketing department and common valve workshop , line with rubber workshop , line with fluorine workshop , engineering workshop , fitting shop and advanced CAD design center. The company has also been constantly improving the inner lining techniques, which has, under strict quality supervision , made it a possibility for the continuous production of high-performance products.
      By constantly improving the common valve series, the company has, at the same time, formed the valve products with resistance to corrosion medium , which are characterized by the line with rubber and the rubber fluorine series. Such products have greatly met the market in its demand for different acid and alkaline resistant valve as well as other valve with resistance to corrosion medium . The inner lining of such materials as BR, NR, CR, FER, RPP, PVD, PTFE and F46 in the valve body of all kinds of cast iron and carbon steel or in the inwall of pipe casting s can not only adapt to corrosion medium under different working condition s, but also can replace a great many rare and precious metal , which has, under the normal working conditions of valve, saved a large amount of funds for the users.
      The enterprise spirit of “ Creation of excellent quality products and accomplishment of great undertaking of Mingjing ” , with the orientation of market , providing the numerous users with ideal and satisfactory service are both the eternal pursuit of the staffs of Mingjing, but all the more the sincere promise to the numerous users!

      消防硬碰硬密封旋球閥類型原理

      1、主要類型:本閥門的主要類型有:蝸輪蝸桿、電動、氣動、液動、其中氣動閥門和液動閥門適合于有壓力氣源和壓力液源的場合。
      2、工作原理:閥芯的密封面為三次曲面,閥座的密封面為1次圓錐面。在密封點處,閥座面實際上是閥芯三次曲面的切面(見圖),因而其結合十分完美。有適應(中心自動定位重合)和補償磨損功能因為轉動中心偏離閥芯幾何中心就有閥芯打開時閥芯實體不斷向后退、向內縮、閥芯關閉時閥芯實體不斷前進、向外脹的實際效果,其功能相當于半
      球閥、閘閥、截止閥、蝶閥的綜合。打開各不同角度變化圖:雙向流閥門zui主要功能是既能在正向壓力時密封良好,在反向壓力或反向壓力大于正向壓力時也能密封良好。當正向壓力作用時,介質壓力推動閥板向前移動,閥桿變形,閥板密封面緊貼閥座密封面?zhèn)鬟f壓力,將閥座推向閥體臺階,使之密封良好。當反向壓力作用時,介質壓力推動閥板向后移動,閥桿變形,介質壓力同時推動閥座密封面緊貼閥板密封面?zhèn)鬟f壓力,將閥座推向閥桿ji限變形位置,使之密封良好。
      消防硬碰硬密封旋球閥不但能在正向壓力下可靠地截斷,在反向壓力或反向壓力遠大于正向壓力時同樣能可靠地密封。該閥密封采用半球閥的結構和原理,外形采用蝶式結構,從而具有:體積小、重量輕的特征;并具有:雙向硬密封、密封摩擦小、經(jīng)久耐用、啟閉輕便等性能,因此,性價比遠高于半球閥。該閥門的成功開發(fā)與運用,是閥門行業(yè)的一次重大技術革新。廣泛應用于水泵出口端、管網(wǎng)系統(tǒng)、回收水系統(tǒng)、高位水槽、易水淹的污水系統(tǒng)、防倒
