蝸輪法蘭球閥產(chǎn)品簡介:
不銹鋼蝸輪球閥可分為浮動(dòng)蝸輪傳動(dòng)球閥和固定蝸輪傳動(dòng)球閥兩大類。浮動(dòng)蝸輪傳動(dòng)球閥的特點(diǎn)是球體可以自由浮動(dòng)。根據(jù)密封座結(jié)構(gòu)不同又分為固定密封座和帶活動(dòng)密封座兩種。固定密封閥座的浮動(dòng)蝸輪傳動(dòng)球閥,結(jié)構(gòu)如圖所示,在閥體內(nèi)裝有兩個(gè)氟塑制成的固定密封閥座,在兩間座之間夾緊一個(gè)由碳鋼或不銹鋼制成的浮動(dòng)球,球體上有圓形通孔,開后時(shí),通道打開;當(dāng)閥桿轉(zhuǎn)動(dòng)時(shí),球孔垂直于閥門的通道,靠介質(zhì)的壓力將球體緊壓在后面的閥座上,保證閥門的密封。

工作原理:
不銹鋼蝸輪球閥一般使用在中大口徑尺寸的管道上,蝸輪傳動(dòng)是在原有的球閥閥桿上接止齒輪箱,只需用旋轉(zhuǎn)很小的轉(zhuǎn)動(dòng)力矩就能實(shí)現(xiàn)開關(guān)。蝸輪傳動(dòng)旋轉(zhuǎn)90°即可全關(guān)全開,啟閉迅速。
產(chǎn)品特點(diǎn):
1、不銹鋼蝸輪球閥只需要用旋轉(zhuǎn)90度的操作和很小的轉(zhuǎn)動(dòng)力矩就能關(guān)閉嚴(yán)密。
2、不銹鋼蝸輪球閥*平等的閥體內(nèi)腔為介質(zhì)提供了阻力很小、直通的流道。
3、不銹鋼蝸輪球閥它具有節(jié)流和控制流量之用。
4、不銹鋼蝸輪球閥的主要特點(diǎn)是本身結(jié)構(gòu)緊湊,易于操作和維修,適用于水、溶劑、酸和天然氣等一般工作介質(zhì)。
