Hanging ball valve pneumatic butterfly valve is used for hoisting equipment to install valves. Hanging ball valve pneumatic butterfly valve assembly components are composed of pneumatic butterfly valve steel frame and ball valve. The following section will introduce the valve principle and installation precautions of the pneumatic butterfly valve of the down hanging ball valve.
Valve principle of pneumatic butterfly valve with suspended ball valve:
The shockproof principle of pneumatic butterfly valve for hoisting ball valve absorbs the flexibility of ball valve with different deflection values, and improves it according to the rating of the required deflection value index. The flexibility flexibility of ball valve can achieve good rebound and elongation effects when the equipment is operating, and has a good shock absorption effect on the hoisting equipment, stabilizing and strengthening the balance of the hoisting equipment, The protective effect is very strong.
Precautions for installation of pneumatic butterfly valve of suspended ball valve:
1. Select the appropriate lifting pneumatic butterfly valve, including the appropriate type of lifting ball valve pneumatic butterfly valve and the correct installation load. Fix the indicator plate of the hanger on the position corresponding to the installation load with the upper and lower positioning blocks, so that the ball valve hanger is in a rigid state and exists stably.
2. The ceiling equipment and lifting equipment shall confirm that the pneumatic butterfly valve is careful and there is no uncertain risk factor to ensure the safety of lifting.
3. After the overall installation, the equipment starts to run. First, check whether the positioning block exists, and then check whether the indicator board is jammed during the displacement process from the installation load to the working load, and whether there is a large amount of displacement.
4. After entering into normal operation, check whether the displacement of the ball valve support under working load is consistent with the design. After the equipment stops running, check whether the indicator board returns to the position where the load is installed. Correct installation data can be obtained by testing the above precautions to ensure stable shock proof effect and safety of the valve.
