Product Description:
Details:
The structure characteristics of Empty row check H48H H48Y
1, the valve is consist of the
check valve, Recycling bypass control valve and throttle device.
2, work with recirculation bypass valve, this valve can prevent the high pressure water hammer damage to the water supply system, to maintain the safe operation of the system.
3, the main valve disc with pipe flow or pressure change and mobile, with the help of medium pressure and spring force close the main valve mouth, then drive the bypass valve open, keep pump minimum allowed flow automatically. When the main valve fully open, the bypass valve is closed.
4 streamline structure design, the use of special valve core, with functions of accurate control flow, under the condition of high pressure difference have cavitation abrasion resistant and not easily get the characteristics of the noise and vibration.
5, the valve sealing surface using cobalt-based hard alloy surfacing and become, wear-resisting, scouring resistance, cavitation resistance, reliable sealing, long service life.
6, maintenance and maintenance convenient and quick
7, the valve is suitable for vertical installation.
Uses:
Empty row check valve installed in a thermal power unit of high pressure feed water pump outlet pipe, to prevent the reverse feed water, protect the feed water pump. The valve with the pump minimum flow by the automatic recirculation valve work, when the feed water pump in low load or export the door closed, automatic recirculation bypass valve should be in an open position, to ensure the safe operation of pump. Its exhaust non-return valve opens, recycle the bypass valve will automatically shut down.
Action principle and structural characteristics
Open the outlet valve, feed water pump start-up, feed water after reaching certain pressure, air exhaust non-return valve valve core automatically rises, away from the seat, feed water flow. At the same time, the valve core rod dynamic emptying valve closed mouth pull emptying. Reduced when the feed water pump flow, valve core, push rod unplug emptying valve, open the recirculation water pump minimum flow. Automatically when the pump stop, valve core falling close the channel, to prevent high pressure water hammer damage to the water supply system.
H48H - 200 air exhaust non-return valve
H48H - 200 empty row check empty row check valve, it is mainly used for power plant feed pump outlet. Work with water pump minimum flow recirculation valve, to maintain safe operation of the system. Action principle is as follows: open the outlet valve, feed water pump starts, feed water after reaching certain pressure, the valve core automatic rising, push the seat, feed water flow. At the same time, the valve core rod dynamic emptying valve closed mouth pull emptying. Reduced when the feed water pump flow, valve core, push rod unplug emptying valve, open the recirculation water pump minimum flow. Automatically when the pump stop, valve core falling close the channel, to prevent high pressure water hammer damage to the water supply system.
