Description of drawings
Fig. 1 is the structural representation of novel swelling water tank of the present utility model.
Wherein label is explained: the 1-casing, and the 2-automatic control pressure vent, the 4-pressure gauge, the 5-Decompression valves, the 6-water pump, the 7-safety check, 8-double threshold pressure switch, the 9-liquid-sighting glass, 10-expansion drum group, 3,11,12,13 are gate valve.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model provides a kind of novel swelling water tank, comprises casing 1, automatic control pressure vent 2, Decompression valves 5, water pump 6, safety check 7, double threshold pressure switch 8, expansion drum group 10; Wherein, described automatic control pressure vent 2 is arranged on the top of casing 1; Described safety check 7, double threshold pressure switch 8 are separately positioned on bottom or the bottom sidewall of casing 1; Described expansion drum group 10 is connected with bottom or the bottom sidewall of casing 1 by pipeline; The bottom of described casing 1 is respectively equipped with waste pipe and system pipes, and an end of described Decompression valves 5 is connected with the top of casing 1 or top sidewall; One end of described water pump 6 is connected with safety check 7, double threshold pressure switch 8 respectively; The other end of the other end of described Decompression valves 5, water pump 6 is connected with waste pipe respectively, and described system pipes is connected with external equipment.
In addition, to be respectively arranged with gate valve be gate valve 3, gate valve 13 to the pipeline that is connected with casing in Decompression valves 5, expansion drum group 10; Joint at described waste pipe and system pipes and casing 1 is provided with gate valve respectively, i.e. gate valve 12, gate valve 11.
The main body of swelling water tank is casing 1, casing 1 top dress automatic control pressure vent 2, and gate valve 3 external pressure gauge 4 and Decompression valvess 5, water pump 6 links to each other with casing by safety check 7.Double threshold pressure switch 8 is by the start-stop of control circuit control water pump 6.Liquid-sighting glass 9 is installed in the casing side, is convenient to visualization.Expansion drum group 10 links to each other with casing by gate valve 13.Gate valve 12 is discharging valve, is used for discharging water maintenance.System pipes links to each other with the equipment of outside need water, and gate valve 11 is used for the start and stop that the control system pipe supplies water.Double threshold pressure switch 8 is the hard contact pressure switch, when the detected pressures value is lower than lower limit, make contact; When the force value that detects reaches the upper limit, the contact disconnects.Expansion drum group 10 is loaded on after the gate valve, and is easy to replace and maintain and be big capacity, effectively pilot pressure fluctuation; And a plurality of combinations backup each other, and improve reliability.
Concrete working procedure of the present utility model is as follows:
When the casing internal pressure is lower than the lower limit of double threshold pressure switch 8, double threshold pressure switch 8 starts water pumps 6.Safety check 7 allows water single flow direction water tank, stops water outflow in the water tank.When the case internal pressure reaches double threshold pressure switch 8 upper limits, water pump 6 stops.During liquid feeding, air is discharged by automatic control pressure vent 2 in the water tank.
When the case internal pressure was higher than the thresholding of Decompression valves 5, Decompression valves 5 was opened automatically, and outwards draining or exhaust reduces pressure, and when the case internal pressure was lower than the thresholding of Decompression valves 5, Decompression valves 5 cut out automatically.Pressure gauge 4 is used for the inspection box internal pressure, and liquid-sighting glass 9 is used for liquid level in the inspection box, all helps to understand and judge the state of system.
In order to realize the level pressure function, the thresholding of the lower limit of double threshold pressure switch 8 and Decompression valves 5 should not have big difference.When in the water system during temperature variation, the volume of system works can change, thereby causes system pressure to change.Therefore can cause the frequent starting of water pump 6 and Decompression valves 5.So need to introduce expansion drum group 10, with the volume change fluctuation absorption, slow down pressure surge, thereby reduce the start-stop number of times of water pump 6 and Decompression valves 5.
Double threshold pressure switch control fluid filling pump of the present utility model start-stop, the low pressure limit of assurance swelling water tank.The upper pressure limit of Decompression valves control swelling water tank.The pressure of swelling water tank is controlled in the scope of setting.Expansion drum group receiving volume changes, and reduces pressure surge, reduces the start-stop number of times of pump and Decompression valves.Prescribe a time limit when the casing internal pressure is lower than under the pressure switch, pump startup adds water to water tank, prescribes a time limit when the casing internal pressure reaches on the pressure switch, and pump stops to add water.When the case internal pressure was higher than the thresholding of Decompression valves, Decompression valves was opened release.The pressure of assurance system is in the scope of setting.Change when temperature variation causes system bulk, the volume change of this moment is held by expansion drum, thereby reduces the pressure surge of system, avoids small pump and Decompression valves frequent starting.The utility model not only complete reservation the major function of swelling water tank, also solved the limited difficulty in mounting point, and structure is simple relatively, control is convenient, reliability, safe can be applicable to vehicle mobile equipment.
