SMDF-DNB Rotating Disc Valve , Dual Plate Swing Check Valve 1.0 MPa Pressure
Production information
. Rotating disc valve employs ceramic or hard metal friction pair structure , which makes it more abrasive and better tightness . It just needs a small starting load because the unique structure . Besides , ashes hardly accumulate in the valve body due to the same reason . All these features make the rotating disc valve durable .
Operating Principle
Applications
. The rotating disc valve can be used in ash conveying system in thermal power plants. It also can be applied in mine , cement plant , lime work , metallurgic plant , chemical factory and other fields that need to convey caustic or abrasive ash .
Technical Parameters
. Maximum operating pressure: 1.0 MPA
. Maximum test pressure: 1.5 MPA
. Operating temperature: ≤ 200℃
. Leakage test pressure: 1.1 MPA
Installation
1. Prior to installation , please read this manual carefully , and check the pneumatic actuator’s condition .
2. Ensure the flange’s dimension , maximum operating pressure and inside nominal diameter meet the requirements .
3. Do not adjust the bolts and nuts . And make sure the center of two pipelines and valve center are coaxial . Flange surface should be smooth and keep horizontal without relatively large slope , for make sure the valve can fasten and work well . Besides , the bolts should be symmetrically fastened .
4. After installation , pump air into the two air intakes of the pneumatic actuator , and make sure the valve plate work properly .
5. If the control switch is installed , ensure its parameters can meet the external power source and it can work properly in fully open or fully close .
Troubleshooting Method
| Troubles | Cause | Troubleshooting Method |
| Leakage | Foreign body | Remove foreign body |
| Seal washer is invalid | Replace seal washer | |
| Valve core abrasion | Replace valve core | |
| Valve cannot open or close | Rotatable parts become flexible or invalid | Adjust or replace the relative parts |
| Insufficient pressure or leakage | Check and repair supply air line | |
| Pneumatic components become ageing or invalid | Replace the relative pneumatic components |
