Background technology
It is much manual pressure release in prior art, when external flow changes, pressure need be readjusted, when not being sure the opportunity of pressure release, be easy to cause danger, use inconvenience, during existing circulation line pressure release, Inner eycle is abundant not, may make the water freezing in heat exchanger and cause pipeline blockage.
Utility model content
The purpose of this utility model is to provide a kind of device with releasing pressure automatically and complete inner loop pipeline, and it has detection external flow and pressure automatically and changes, prevents the feature of pipeline blockage, to solve the problems referred to above existed in prior art pressure leak process.For reaching this object, the utility model by the following technical solutions:
There is a device for releasing pressure automatically and complete inner loop pipeline, comprise water tank, water pump, plate type heat exchanger, triple valve, relief valve, outer loop pipeline, water level pipe, Pressure gauge, drainpipe, pressure control switch, magnetic valve and pressure regulator valve, wherein the delivery port of water tank is connected with water pump by pipeline, and the delivery port of water pump is connected with triple valve by pipeline, and the water that triple valve upper end is flowed out passes through pipeline, relief valve reflow tank, the water that triple valve right-hand member flows out flows to plate type heat exchanger through outer loop pipeline, the delivery port of plate type heat exchanger is connected with water tank by pipeline, pressure control switch lower end is connected with outer loop pipeline, the pressure size of the delivery port automatically detected can be passed through like this, the break-make of pressure switch is regulated according to the application of reality, to ensure that in the process of decompression cycle cooling water is continuable and flow through plate type heat exchanger, the fluctuation of effective minimizing water the temperature inside the box, make temperature control more accurate, pressure regulator valve lower end is connected with plate type heat exchanger leading portion, even if outer loop pipeline blockage or dam like this, during internal pressure relief, the water outlet of water pump can pass through triple valve, and then passes through pressure control switch, magnetic valve, pressure regulator valve flows to plate type heat exchanger, can not cause plate type heat exchanger inner icing, pipeline blockage.
Further, the left end of water tank is connected with water level pipe, and can be inferred the surplus of water inside water tank like this by water level pipe, the lower end of water tank is connected with drainpipe.
Further, Pressure gauge is connected with triple valve left end by pipeline, can detect the pressure of water pump water outlet pipeline like this.
The beneficial effects of the utility model are: the change that 1) automatically can detect external flow and pressure, make corresponding pressure and regulate with this to while meeting external pressure demand, ensure the normal work of pump according to change.2) inner loop pipeline is connected to the water circulation that heat exchanger leading portion fully can ensure heat exchanger inside, prevents water freezing, pipeline blockage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model; Fig. 2 is circulation line schematic diagram of the present utility model.
Wherein, 1 water tank, 2 water pumps, 3 plate type heat exchangers, 4 triple valves, 5 relief valves, 6 pressure control switch, 7 magnetic valves, 8 pressure regulator valves, 9 outer loop pipelines, 10 water level pipes, 11 Pressure gauges, 12 drainpipes.
Detailed description of the invention
In order to understand the utility model further, below in conjunction with drawings and Examples, the utility model preferred embodiment is described.
Circuit design of the present utility model as shown in Figure 1, comprise water tank 1, water pump 2, plate type heat exchanger 3, triple valve 4, relief valve 5, pressure control switch 6, magnetic valve 7 and pressure regulator valve 8, outer loop pipeline 9, water level pipe 10, Pressure gauge 11, drainpipe 12, the left end of water tank 1 is connected with water level pipe 10, the lower end of water tank is connected with drainpipe 12, the delivery port of water tank 1 is connected with water pump 2 by pipeline, the delivery port of water pump 2 is connected with triple valve 4 by pipeline, Pressure gauge 11 is connected with triple valve 4 left end by pipeline, the water that triple valve 4 upper end is flowed out passes through pipeline, relief valve 5 reflow tank, the water that triple valve 4 right-hand member flows out flows to plate type heat exchanger 3 through outer loop pipeline, the delivery port of plate type heat exchanger 3 is connected with water tank 1 by pipeline, pressure control switch 6 lower end is connected with outer loop pipeline 9, pressure regulator valve 8 lower end is connected with plate type heat exchanger 3 leading portion.
Operation principle of the present utility model as shown in Figure 2, cooling water in water tank 1 is added by water pump 2 and is sent to outlet pipe, after outer loop pipeline, water temperature rising enters plate type heat exchanger 3 and carries out first time cooling, return in water tank 1 afterwards, a triple valve 4 is added for adjusting water outlet pressure in the exit of water pump 2, pressure control switch 6, magnetic valve 7, in pressure regulator valve 8(dotted line frame), the pressure size at the mouth of a river can be detected automatically, the break-make of pressure switch is regulated according to the application of reality, and in the process of decompression cycle, cooling water is continuable flows through plate type heat exchanger 3, effectively can reduce the fluctuation of water the temperature inside the box, make temperature control more accurate.When outer loop pipeline blockage or when damming, the pipeline that internal pressure relief makes the water outlet of water pump 2 connect through pressure regulator valve 8, flows to plate type heat exchanger 3, can not cause plate type heat exchanger inner icing in this case, pipeline blockage.The circulation line that machine adopts can realize the circulation of plate type heat exchanger inside, thus avoids the appearance of above problem.
The foregoing is only preferred embodiment of the present utility model; it should be pointed out that for the ordinary skill in the art, do not departing under principle prerequisite of the present utility model; can also make various deformation and improvement, this also should be considered as protection domain of the present utility model.
