  • Product description
    100D water valve is a valve diaphragm type adjustment tank and water tower in height. The valve is controlled by the floating ball, when the liquid level reaches the set height, the valve passes the signal through the relevant structure to transfer a water pump, and the water pump stops the water supply; when the liquid level bottom is in the set position, the water pump automatically supply water. The valve action is stable and effective to prevent the opening of the pump water hammer and stop pump water hammer. Avoid excessive pressure on the pipe. Automatic water supply system for water tank, a water tower. The valve maintenance is simple, flexible and durable, high accuracy of level control, the water level is not affected by water pressure interference and close tight, reliable performance.

  • Valve maintenance
    (1) the engineering application of the hydraulic control valve is a manufacturing plant inspection, a variety of complete, technical information to meet the requirements of the product.
    (2) the nominal pressure of the valve has different levels, the pipeline transportation of the media, the working pressure should be less than the value of the valve nominal pressure.
    (3) the project of the hydraulic control valve setting should have enough space for management, operation, installation and maintenance, and should meet the requirements of the pipeline valve.
    (4) when the pipe is connected by flange, the hydraulic control valve with flange connection should be adopted, and the hydraulic control valve with groove connection should be adopted when the pipeline is connected with a groove.
    (5) the hydraulic control valve should be set on the one-way flow of media in the pipeline.
    (6) the direction of the arrow on the main body of the hydraulic control valve must be consistent with the direction of the pipeline system.
    (7) the water control valve should not have gas blocking, air resistance. Automatic exhaust valve should be set at the highest position of the pipe network.
    (8) when the valve is installed, the valve cover and valve stem should be facing up. Vertical installation, valve cover, valve stem should be outward.
    (9) the valve should be done before the installation of strength and tightness test.
