First, working principle
When the water tower water level dropped, the floating ball valve open drainage pipe, water pressure valve piston will hold up in the water, sealing the open water supply valve is open, when the water level rises to the control valve, float valve closed, the sealing surface will be closed down, the valve to stop water supply.


 

Two. Technical parameters
Use medium: Hao Jing water
Use pressure: Hl42x4TA, Hl42x 1 4, A:005MPa ~ 04MPa
H142X 10—A:O 05MPa~1MPa
Medium temperature: less than or equal to 60 DEG C


 

Three, performance characteristics
1. using hydraulic principle control, the structure is novel and reasonable.
2. stable and reliable work. In the specified range of use pressure can ensure the impact of anhydrous hammer.
3. light weight, small size.
4 convenient installation and maintenance.

Five, installation forms and matters needing attention
The valve is vertically fixed on the inlet pipe, and then the control tube, the stop valve and the float valve are connected and screwed on the valve. The valve inlet pipe and outlet pipe connecting flange Hl42x 4T - A is 06MPa standard flange; Hl42x10 - A is IMPa standard flange. The diameter of the inlet pipe shall be greater than or equal to the nominal diameter of the valve, and the outlet should be lower than the float valve. The installation of floating ball valve should be more than one meter away from the water pipe; in order to prevent siphon backflow, the outlet pipe of the water tank should be slightly higher than the control level. In order to prevent noise and water level fluctuation, the outlet should be equipped with energy dissipator. When used, the cut-off valve should be fully open, as the installation of more than two valves in a pool should maintain the same level. Because the main valve closed to float behind the ball valve l only about 30~50 seconds J, so the tank should have enough spare volume, in order to prevent overflow. In order to prevent the impurities and sand from entering the valve and cause the malfunction of the work, the filter should be installed before the valve.
If installed in the basement pool, the alarm should be installed in the underground pumping station.
This product is only to provide the hydraulic valve and the float valve, the rest of the equipment made by the user or purchase.
