[3] beneficial effect
The present invention regulates pressure fixing valve, can ensure the pressure in pipeline when opening raw water service pump, by regulating the mechanical device in pressure fixing valve, after setting certain pressure, pressure at both sides in pipeline is regulated automatically.Under pressure of supply water is beyond one's reach situation, pressure cannot meet the requirements of water by regulating pressure fixing valve to regulate the mechanical device of pressure fixing valve to ensure, now proves that user side uses.And when customer volume is less, when hot water needs to loop back in the middle of water tank, regulate pressure fixing valve the water of small flow can be made by this adjustment pressure fixing valve by the automatic Open valve of pressure of setting, ensure that the hydraulic pressure in user's side ducts reaches usage requirement simultaneously.The present invention regulates pressure fixing valve to pass through to rotate clockwise handwheel, lift-bolt, and the spring retaining sleeve positioning pressure of screw rod adjustment spring, by pressure-adjusting spring, makes manger board contact with valve body water hole, to stop operating handwheel until pressure reaches requirement.Valve also can do sealing use simultaneously, and when pressure-adjusting spring is close to Pressure maximum value, the bottom contact guide pillar of screw rod, makes manger board thoroughly seal water hole, reach the object of sealing.
