Pressure reducing valve in the application of the technical water supply system for hydropower station
After ZJY46H modular pressure reducing valve and pressure relief of fluid through a water filter to filter, then through hydraulic control valve into the water. If the pipeline overpressure, relief valve will be fully open and pressure in a timely manner.
1, the combined valve on the premise of ensure the unit water use, for the valve after water points to provide stable and reliable low pressure cooling water. Its maximum stress ratio up to now. Combined type pressure reducing valve equipment recoil poor drainage system can be applied on medium, safety lock system is to ensure that the system has been seriously damaged outlet pressure remains low pressure.
2, the technical water supply system installed on a water filter, can provide the crew with clean water, to prevent impurities into the damaged unit. Water filter if the installation after the combined type pressure reducing valve, the user can choose a smaller pressure level of the water filter, but too much impurities will affect the stability of the pressure reducing valve performance.
3, the technical water supply system of hydraulic control valve can be closed by a rapid opening and slow to truncate the pipeline medium flow and eliminating water hammer pressure of pipe. Good performance of the hydraulic control valve in the open and closed at the same time can be recoil drainage, ensure the BuKa resistance condition.
4, pressure release valve on the technical water supply system can accurately maintain pipeline safety pressure, once the pipeline more than setting pressure, pressure relief valve will be fully open and pressure in a timely manner. Good performance of the pressure relief valve in addition to have a feedback system, also with forced open handle, in one thousand the failure of the swappable feedback system or manual directly.
