Pneumatic valve, corrugated pipe lining fluoride security WA42F46) Using the matters needing attention

corrugated pipe pneumatic valve fluorine-butterfly security ( WAF） Commonly used in chlor-alkali, liquid chlorine, hydrochloric acid and other chemical industry corrosive, harmfulness, pure, and contains a small amount of solid medium equipment or piping, pneumatic valve opening and closing pieces under the action of external force in a normally closed state, but when the equipment or piping within the medium pressure than specified value, the spring jacking pneumatic disc excretion outward pressure, to ensure the safe operation of the equipment. Corrugated pipe pneumatic valve fluorine-butterfly security in daily use, must pay attention to the following contents:
a pneumatic valve, corrugated pipe lining fluorine security using department should be in the process and post operation procedures, the corrugated pipe pneumatic valve fluorine-butterfly safety clearly put forward the following safety operation requirements: operation, process indicators ( Including the maximum working pressure, the highest working temperature or the lowest temperature and the pressure setting. , corrugated pipe pneumatic valve fluorine-butterfly safety considerations and operation method, Only with a wrench pneumatic valve fluorine-butterfly security. Pneumatic valve, corrugated pipe lining fluorine safety should be focusing on in the operation of the project, the possibility of abnormal phenomenon and the prevention measures, as well as the emergency disposal and reporting procedures. The safety in the operation of the pneumatic valve, corrugated pipe lining fluorine should be regularly check, inspection cycle is formulated by using units according to the specific situation, should not be longer than once a month. Check should focus on the following items:, nameplate is complete; , corrugated pipe pneumatic valve fluorine-butterfly security seal are in good condition; , and safety of corrugated pipe lining fluorine pneumatic valve used to cut off the pneumatic valve is fully open, seal are in good condition; Whether, in the operation of the abnormal; Whether, in the operation of more than setting pressure flexible takeoff. Three pneumatic valve, corrugated pipe lining fluorine safety in use process, the following problems, the operator should report to relevant departments timely according to the prescribed procedures, and overpressure don't jump; , not to return after takeoff; And leak; Pneumatic valve, corrugated pipe lining fluorine security before cut off the pneumatic valve and safety valve seal off. Four, pressure vessel in the process of running, corrugated pipe pneumatic valve fluorine-butterfly safety before should cut off the pneumatic valve is in full open position and seal. Prohibit any security pneumatic valve cap to death, cancel or close to cut off the pneumatic valve. Change security pneumatic valve operation must be approved by the competent leadership. Five pneumatic valve, corrugated pipe lining fluorine safety belt pressure at work, it is forbidden to make any repairs and tighten. Need to repair and so on a work, use the unit should make effective operation requirements and protective measures, and subject to consent by the technical director, in the actual operation of security department must be sent to site supervision. Sixth, it is forbidden to operators who opens without authorization seal or adjust the corrugated pipe lining fluoride safety pneumatic valve adjusting screw. Seven, spare corrugated pipe lining fluorine pneumatic valve should be properly kept and maintained safely.
