Fully automatic water control valve works

  Fully automatic water control valve works

     1, water pump before the start of static pressure at the valve off. Pump starts, water from the valve side of the bypass pipe imports into the cavity under the diaphragm chamber, the diaphragm, together with the valve stem and small plates slowly lifted. At the same time, large valve plate is also under pressure in the inlet opens.

     2, with the water flow and pressure, diaphragm, together with the stem and the large and small valve on-board rose to a high rating (which can visually signal poles).

     3, when the pump stops, the valve to stop imports of polyethylene water flow, pressure reducing, large backwater valve plate in the self-determination and quickly fell under pressure until the complete access seat.

     4, with the return water pressure, water from the export side of the bypass pipe into the room on the diaphragm chamber to promote the diaphragm, together with the stem and the small stem and the small valve plate slowly down. At this point, the inferior vena diaphragm chamber of water through the valve on the left side of the bypass pipe flow back imports. When the small valve plate completely closed a large valve ring between the plate and stem Discharge port when the valve has fully recovered before the start of the static pressure to the pump off.

     Fully automatic water control valve failure causes and to exclude measures

     1, the signal pole vertical speed is not normal because:

     1, a small bypass valve or filter clogging;

     2, platen or rubber diaphragm rupture or Die room too much debris;

     3, the small valve was artificially closed.

     Second, troubleshooting measures are:

     1, check a small bypass valve handle position is correct;

     2, cleaning of small valves and filters;

     3, check the rubber diaphragm chamber, if the rubber diaphragm or pressure plate rupture must be replaced immediately.

     3, internal leakage is too large because:

     1, large and small valve plate seal damage;

     2, large and small debris blocking valve plate plane are separated;

     3, valve stem on mouth or debris.

     4, troubleshooting measures are:

     1, check the large and small valve board rubber seals, if he has damaged it is immediately replaced;

     2, stop pumps remove large and small valve plate, valve seat and valve stem on the debris;

     3, re-assembly, they must be clean of all parts.
