Jiangqiao Industrial Zone is characterized by elegant environment and convenient transport. The group is a professional manufacturer that integrates study, design, development and sale of all kinds of common valves, a ntiseptic v alve and internally piloted valve . 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!

      高靈敏度蒸汽減壓閥 產(chǎn)品信息

      圖片相關(guān)說明:
         
       
      結(jié)構(gòu)特點和用處
          YG13H/Y型內(nèi)螺紋連接高靈敏度蒸汽減壓閥屬于先導(dǎo)活塞式減壓閥。由主閥和導(dǎo)閥兩部分組成。主閥主要由閥座、主閥盤、活塞、彈簧等零件組成。導(dǎo)閥主要由閥座、閥瓣、膜片、彈簧、調(diào)節(jié)彈簧等零件組成。通過調(diào)節(jié)調(diào)節(jié)彈簧壓力設(shè)定出口壓力、利用膜片傳感出口壓力變化,通過導(dǎo)閥啟閉驅(qū)動活塞調(diào)節(jié)主閥節(jié)流部位過流面積的大小,實現(xiàn)減壓穩(wěn)壓功能。
          本系列產(chǎn)品在普通減壓閥基礎(chǔ)上做了以下改進,加大了活塞面積,改變了節(jié)流結(jié)構(gòu),改變了密封形式,改進了導(dǎo)閥結(jié)構(gòu)和調(diào)節(jié)彈簧形式,從而從以下幾方面提高了產(chǎn)品的性能。
          1、提高了對出口壓力變化的傳感效能,提高了靈敏度,大大降低了因上游壓力變化,流量變化等因素引起的壓力偏差。
          2、改善了流線分布,降低了噪聲。
          3、改進了密封面結(jié)構(gòu),延長了密封面壽命。
          本產(chǎn)品主要用于蒸汽管路,適用于進口壓力變化大,流量變化大的蒸汽管路。
