The further improvement project of the present invention is, described tube connector comprises large port, portlet and be connected transition portion between the large and small port that the top of described large and small port and transition portion is on same straight line.
The present invention further improvement project is that described large port is communicated with described secondary net backwater trunk line welding, is welded with the flange that is connected with described pump entry end on the described portlet end face.
The present invention further improvement project is that the radius of described portlet is identical with the opening radius of described pump entry end adpting flange.
The present invention further improvement project is that the radius of described large port is greater than the radius 2-5cm of described portlet.
The present invention further improvement project is that the junction into and out of pipe of described bypass pipe and described second fluid lays respectively at the outside of described inlet valve, outlet valve.
The present invention further improvement project be described bypass pipe two ends be welded on described second fluid on the tube wall of pipe.
The present invention further improvement project is that described automatic decompression device is the pressure release magnetic valve that is electrically connected on heat exchange machine industrial control system.
The present invention further improvement project is that described sluice pipe is provided with filter.
The present invention further improvement project is that described filter bits is in the upstream of described pressure relief device.
The present invention compared with prior art has the following advantages:
One, the tube connector between secondary net backwater trunk line of the present invention and the circulating pump adopts eccentric reducer, can significantly reduce the cavitation in the pipeline, prevent that gas enters the pump chamber damage pump housing in the pumping hole gathering in the pipeline, slow down the corrosion of inner-walls of duct, prolong service life, saved the cost of heat exchange machine regular maintenance.
Two, the control valve of bypass pipe of the present invention is in normally off when heat exchanger carries out the fluid heat exchange, does not influence the operate as normal of heat exchange machine.In second fluid occurring during the too much situation of impurity, close advancing of second fluid, outlet valve, open the control valve of bypass pipe, fluid is under the effect of circulating pump, enter secondary host pipeline, discharging from going out pipe again from the inlet pipe inflow bypass pipe of second fluid through once filtering the back, the fluid of discharging passes through secondary host filter pipeline again under the effect of circulating pump, discharge, so circulation, treat that contaminant filter is complete, close the control valve of bypass pipe and open advancing of second fluid, go out valve, the use of the present invention impurity in multiple times of filtration second fluid that can circulate, guarantee that the runner on the heat-exchanger ripple plate is not blocked, and then guarantee the operating efficiency of heat exchanger.
Three, sluice pipe of the present invention is provided with the pressure release magnetic valve, thereby the pressure in the Open valve draining releasing tube automatically when the pressure in the secondary net backwater trunk line surpasses safety value, the delivery port of sluice pipe is positioned at the top of water tank, the draining of tapping pipe does not directly mix the normal moisturizing that just not can produce the aeration small pump with the water inlet of small pump yet, guarantee the continuous operation of heat exchange machine, improved heat exchange efficiency.
