Abstract
The utility model discloses a kind of heat exchange station small pump automatic exhaust system, including exhaust system and control system；Exhaust system includes small pump and the tapping pipe being connected with the exhaust outlet of small pump；Control system includes pressure sensor, controller, timer and solenoid valve；Solenoid valve is arranged on tapping pipe；Pressure sensor is arranged in the moisturizing pipeline of small pump；The pressure signal detected is transmitted to controller by pressure sensor, and controller controls the break-make of solenoid valve according to the size of pressure signal with the operating time of timer statistics small pump；The heat exchange station small pump automatic exhaust system can be exhausted according to the pressure in small pump moisturizing pipeline and the run time of small pump by opening solenoid valve, avoid the occurrence of the hidden danger of artificial exhaust leak.
Description
Technical field
Energy technology field is the utility model is related to, more particularly to a kind of heat exchange station small pump automatic exhaust system.
Background technology
In Heating Season, heat-exchange unit needs to be continued for running, but often nest occurs in small pump due to various reasons
The situation of gas, causes moisturizing to arrive rated pressure, causes system to maintain operating pressure；Small pump long-play is not only
The problem of causing to damage, also common people can be caused indoor not hot in itself to the pump housing.In addition, if artificial exhaust is, it is necessary to often
Rotation small pump carries bleeder screw, is loosened since the reasons such as misoperation are likely to result in bleeder screw, does not only exist leak
Hidden danger, the water in the pump housing can also be splashed on ground, influence environmental sanitation in heat exchange station when deflating.
Utility model content
The purpose of this utility model is to provide a kind of heat exchange station small pump automatic exhaust system.
For this reason, technical solutions of the utility model are as follows：
A kind of heat exchange station small pump automatic exhaust system, including exhaust system and control system；
Exhaust system includes small pump and the tapping pipe being connected with the exhaust outlet of small pump；
Control system includes pressure sensor, controller, timer and solenoid valve；Solenoid valve is arranged on tapping pipe；Pressure
Force snesor is arranged in the moisturizing pipeline of small pump；The pressure signal detected is transmitted to controller by pressure sensor, control
Device processed controls the break-make of solenoid valve according to the size of pressure signal with the operating time of timer statistics small pump.
Preferably, it is additionally provided with ball valve on the pipeline between the solenoid valve and moisturizing pump exhaust inlet.
Preferably, the tapping pipe is fixed on the exhaust outlet of small pump by connector.
Compared with prior art, which can be according to the pressure in small pump moisturizing pipeline
Power and the run time of small pump are exhausted by opening solenoid valve, and avoid the occurrence of causes due to choking with resentment in small pump pipeline
Not hot situation in heating user room；At the same time, which alleviates the labor of staff
Fatigue resistance, reduces maintenance cost, economical and practical；In addition, which avoids artificially
The hidden danger of leak is vented, the hot water that when exhaust discharges can be exhausted directly to waste pipe by tapping pipe, keep in heat exchange station
Cleaning.
Brief description of the drawings
Fig. 1 is the structure diagram of heat exchange station automatic exhaust system provided by the utility model.
Fig. 2 is the control structure block diagram of automatic exhaust system.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further the utility model, but following embodiments are right absolutely not
The utility model has any restrictions.
As shown in Fig. 1~2, which includes exhaust system and control system；
Exhaust system includes small pump 1 and the tapping pipe 4 being connected with the exhaust outlet of small pump 1；
Control system includes pressure sensor 6, controller 7, timer 8 and solenoid valve 5；Solenoid valve 5 is arranged on tapping pipe 4
On；Pressure sensor 6 is arranged in the moisturizing pipeline of small pump 1；The pressure signal detected is transmitted to control by pressure sensor 6
Device 7 processed, controller 7 control solenoid valve 5 according to the size of pressure signal with the operating time of the statistics small pump 1 of timer 8
Break-make.
Ball valve 3 is additionally provided with pipeline between 1 exhaust outlet of solenoid valve 5 and small pump.
The tapping pipe 4 is fixed on the exhaust outlet of small pump 1 by connector 2.
The course of work of heat exchange station small pump automatic exhaust system provided by the utility model is as follows：
At work, ball valve 3 is in normally open to the heat exchange station small pump automatic exhaust system, and controller 7 connects in real time
The operating pressure of the small pump 1 detected from the moisturizing pipeline pressure sensor 6 for being arranged on small pump 1 is received, at the same time,
Timer 8 carries out timing to the run time of small pump 1, and timing result is sent to controller 7 in real time；Controller 7
The information sent according to pressure sensor 6 and timer 8 judges whether small pump 1 meets the situation for occurring choking with resentment, then as judged knot
Fruit is "No", then continues to judge；If it is determined that result is "Yes", then controller 7 controls solenoid valve 5 to open, and small pump 1 carries out
It is vented, the liquid sputtered in exhaust process is discharged into waste pipe by tapping pipe 4, after reaching setting evacuation time, electricity
Magnet valve 5 is again switched off, and after the completion of an exhaust process, 8 automatic clear of timer.
When staff needs to overhaul solenoid valve 5, ball valve 3 is closed, examines solenoid valve 5 whether can be normal
Opening and closing.
