| 结构特点 | structure feature: |
| 1、全通径结构，流体阻力小，开关迅速、方便。 2、可靠的阀座密封.采用双斜面弹性密封圈、降低了摩擦系数。减少铡乍扭矩，保证低压、高压有可靠的密封.如图1。 3、当介质的冲刷力较大时.特别设计的阀座防冲刷结构能有效防止介质的冲刷,bbl呆使用寿命.如图2。 4、可靠的阀个F&封.阀杆倒密封结构，可防止阀杆脱出和保护填料不受破坏。 5、球阀内通道光滑，可输送粘性介质、浆液粉尘及固体颗粒。 | 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. |
