Precautions for Installation of Pneumatic Ball Valve
Pneumatic ball valveIt is widely used in our days, so let's introduce the pneumatic ball valve device. 1. Before the device, remove the maintenance cover of the two sections of the pneumatic ball valve and clean it after it is completely opened. Then, the signal should be tested so as not to affect the use of the valve.
Pneumatic ball valveIt is widely used in our days, so let's introduce the pneumatic ball valve device.
1. Before the device, remove the maintenance cover of the two sections of the pneumatic ball valve and clean it after it is completely opened. Then, the signal should be tested so as not to affect the use of the valve.
2. Before connecting the pipeline and the pneumatic ball valve, some residual substances that may exist in the bite pipeline should be cleaned to avoid damage to the valve seat by impurities. When the device is installed, the lifting point should be the executive part of the valve body, otherwise the actuator will be damaged.
3, pay attention to adhere to the valve straight device, so as to ensure the use of the role.
4. Ensure that the position of the pneumatic ball valve device is in the coaxial position. The two flanges on the pipeline should be parallel. It is admitted that the pipeline can bear the weight of the pneumatic ball valve itself. If it is found that the pipeline cannot bear the weight of the pneumatic ball valve, the pipeline should be equipped with corresponding support before the device.
5, admit whether there are impurities, welding slag, etc. in the pipeline, must be purged clean.
6, check the pneumatic ball valve nameplate, and fully open and fully closed several times of operation, admit that the valve can operate normally, and then fully check the details of the valve to ensure that the valve is intact.
7. Remove the maintenance cover at both ends, check whether the valve body is clean, and clean the inner cavity of the valve body, because the sealing surface of the pneumatic ball valve is in the shape of a ball, even small debris may cause damage to the sealing surface.
pneumatic ball valve device:
1. The sealing gasket shall be installed between the pneumatic ball valve flange and the pipeline flange according to the pipeline design requirements.
2. The bolts on the flange shall be tightened symmetrically, successively and evenly.
3. When the ball valve adopts pneumatic actuator, complete the air source device according to the instructions.
4. Any section of the pneumatic ball valve can be set at the upstream end, and the handle pneumatic pipeline ball valve can be set at any position of the pipeline. If the ball valve with electric-pneumatic actuator is configured, a straight device is required, and the inlet and outlet of the valve are in a horizontal position.,
