美國泰樂TYLER進(jìn)口蝸輪蝶閥
產(chǎn)品描述-
美國泰樂TYLER進(jìn)口蝸輪蝶閥利用齒輪箱來帶動(dòng)圓盤形閥瓣,閥板只需旋轉(zhuǎn)90度即可快速啟閉，操作簡單，極其省力,并且在齒輪箱上有開度指示,能清楚地了解閥板開關(guān)的位置。
結(jié)構(gòu)原理-
▲金屬密封閥門的設(shè)計(jì)是采用三偏心結(jié)構(gòu)原理，利用了固有的凸輪效應(yīng)，*消除了90度行程中閥座與密封圈之間的全部摩擦;
▲橡膠軟密封蝶閥的設(shè)計(jì)采用了單偏心結(jié)構(gòu)，與中線軟密封不同,蝶板轉(zhuǎn)動(dòng)大約在20度之后，閥座與密封圈之間迅速脫離，從而減少摩擦;
產(chǎn)品特點(diǎn)-
低扭矩,操作靈活；
流通性能好;
無泄漏,開關(guān)迅速;
采用偏心結(jié)構(gòu),閥座與蝶板無乎無磨擦;
具有越關(guān)越緊的密封功能;
密封圈選用不銹鋼制作，具有金屬硬密封和彈性密封的雙重優(yōu)點(diǎn);
應(yīng)用范圍-
蝸輪傳動(dòng)蝶閥具廣泛應(yīng)用到造紙、石化、化工、冶金、電力、制藥、化肥、環(huán)保、石油、廢氣凈化裝置、燃?xì)狻⒄羝O(shè)備、造船業(yè)、輕工等工業(yè)部門的自動(dòng)化控制系統(tǒng)中的水、油品、氣體、液體、蒸汽、冷卻水等腐蝕性與非腐蝕性介質(zhì);

The American TYLER imported worm valve
Product description -
American wessing TYLER import worm gear butterfly valve gear box is used to drive the disc disc, can rapid opening and closing valve plate can rotate 90 degrees, simple operation, save Labour, and on the gear box has the opening instructions, can clearly understand the position of the valve plate switch.
Principle of structure -
The design of the metal seal valve is adopted with the principle of the three-eccentric structure, which utilizes the inherent CAM effect to compley eliminate all the friction between the seat and the sealing ring during the 90-degree stroke.
Bring the rubber sealing butterfly valve was designed with single eccentric structure, different from the midline soft seal, after about 20 degrees in butterfly plate rotation, quickly from between the seat and seal, thereby reducing the friction;
Product features -
Low torque, flexible operation;
Good circulation performance;
No leakage, fast switch;
Using eccentric structure, the seat and butterfly plate are not friction-free.
The sealing function with the closer and tighter;
The sealing ring is made of stainless steel with double advantages of hard sealing and elastic sealing.
Application scope -
Worm gear butterfly valve is widely used to make paper, petrochemical, chemical, metallurgical, power, pharmaceutical, chemical fertilizer, environmental protection, oil, waste gas purification plant, gas, steam equipment, shipbuilding, light industry and other departments of industry automation control system of water, oil, gas, liquid, steam and cooling water and other corrosive and non corrosive medium;
