手動浮動球球閥、氣動浮動球球閥、 電動浮動球球閥、 渦輪浮動球球閥
| 結構特點 | structure feature: |
| 1、全通徑結構，流體阻力小，開關迅速、方便。 2、可靠的閥座密封.采用雙斜面彈性密封圈、降低了摩擦系數(shù)。減少鍘乍扭矩，保證低壓、高壓有可靠的密封.如圖1。 3、當介質的沖刷力較大時.特別設計的閥座防沖刷結構能有效防止介質的沖刷,bbl呆使用壽命.如圖2。 4、可靠的閥個F&封.閥桿倒密封結構，可防止閥桿脫出和保護填料不受破壞。 5、球閥內通道光滑，可輸送粘性介質、漿液粉塵及固體顆粒。 |
1.All diameter stnuctuue, seal fluid iEsistanoe, rapid andeasy open and close. 2. Reliable valve seat seal adopts double-bevel elastic sealing, which lowers the abrasive coefficient, obaease the operation torque, ensure reliable low and high pressuue seal. 3. When the scouring force of media is larger, the anyi-scouring structure speaally designed for valve seat can efficiently prevent the scauing of media and ermure the use life. 4. Reliable valve handle seal and back seal structure of valve handle can prevent the valve handle from deviation and protect the filling from damafe. 5. The smooth channel in the ball valve can transport theglutinous media, serous dust and solid particle. |
