Valve as an important control device in the piping system, its operation precautions for the safe operation of the system is critical. The following are some precautions about valve operation:
1. Before operating the valve, make sure that the system is shut down and have enough understanding of the purpose and working principle of the valve.
2. the valve should be operated according to the type of valve to choose the correct operating method, not forcibly screwed or operated with tools, so as not to damage the valve.
3. in the operation of the valve should pay attention to the size of the operating force, do not use too much force to operate, so as not to cause damage to the valve or malfunction.
4. when operating the rotary valve, pay attention to the direction and amplitude of rotation to ensure that the rotation does not exceed the scope of the design requirements.
5. When opening or closing the valve, do it slowly so as not to cause accidents due to sharp pressure changes in the pipeline.
6. When opening or closing the valve, the operating force should be increased or decreased gradually, without sudden force.
7. When operating the valve, always pay attention to the working condition of the valve, once found abnormal phenomenon should stop the operation in time, and carry out inspection or maintenance.
8. before operating the valve should first check whether there are obstacles around the valve to ensure the smooth operation.
9. when operating the valve should always keep sober, not after drinking, fatigue or mental inattention to the state of operation.
10. operation is completed in a timely manner to restore the valve to a normal or safe position, and make relevant records and markings.
