The technical scheme adopted by the utility model for solving the technical problems is to provide a precise water supplementing and pressure relieving heat exchanger unit, which comprises a heat exchanger, a circulating water pump, a Y-shaped filter, a water supplementing system, a pressure relieving system and a control system; a circulating water inlet of the heat exchanger is connected to a circulating water pump outlet, a circulating water pump inlet is connected to a Y-shaped filter outlet, a Y-shaped filter inlet is connected to a tail end water return pipe, and a pressure sensor is arranged on the tail end water return pipe; the water supplementing system comprises a water supplementing pipe, an upper water electromagnetic valve and a matched valve pipeline, wherein one end of the water supplementing pipe is connected with a tap water supply pipeline, the other end of the water supplementing pipe is connected with the upper water electromagnetic valve, and the upper water electromagnetic valve is connected to an inlet of the Y-shaped filter through a pipeline; the pressure relief system comprises a pressure relief electromagnetic valve and a matched valve pipeline, one end of the pressure relief electromagnetic valve is connected to the outlet of the Y-shaped filter, and the other end of the pressure relief electromagnetic valve is connected to the drainage ditch; the control system comprises a control cabinet and a signal wire, wherein the control cabinet is respectively connected to the pressure sensor, the pressure relief electromagnetic valve and the water supply electromagnetic valve through the signal wire.
Furthermore, a Y-shaped filter is also arranged on the water replenishing pipe.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses can effectively reduce the fault rate, the system operation is more stable, protection water pump and system safety. Because the system operation produces the vibration, teletransmission manometer and electric contact manometer are pointer form and the dial plate is glass, and easy vibrations are bad, lead to system's pressure to rise continuously, can cause the explosion danger seriously.
2. The utility model discloses can make the precision promote greatly, reduce the waste of water resource, the manometer precision level is 1.6 grades, and the pressure sensor precision level is 0.5 grade, and it can accurate control to go up water solenoid valve in the moisturizing, avoids pressure to reach, but the signal precision is not enough, causes to sluiced again after the system moisturizing is too much, because the moisturizing is the running water, nevertheless sluiceway is all arranged to the sluiceway, causes the waste greatly of water resource.
3. The utility model discloses reducible investment cost and construction cost replace electric contact manometer and teletransmission manometer with a pressure sensor, reduce the investment cost in initial stage, also reduced because the later stage replacement cost that the trouble arouses, and only get a measurement station at the trunk line when the construction, connect a signal line can.
