Abstract
It the utility model is related to a kind of automatic priming device of centrifugal pump.Sealed on the outlet pipe at sealing fixed water inlet pipe and outlet pipe on centrifugal pump, outlet pipe concatenation non-return valve and main valve, non-return valve and main valve both ends by tank pump line and connect electronic filling pump valve；One end of the fixed bleeder pipe communicated therewith is sealed on described water inlet pipe, the other end of bleeder pipe fixes electronic vent valve, and the position of electronic vent valve is higher than described centrifugal pump；Described electronic filling pump valve, electronic vent valve electrically connect with the control device of centrifugal pump.It is simple in construction, and cost is low, and automaticity is high.
Description
Technical field
It the utility model is related to a kind of priming device, the automatic priming device of more particularly to a kind of centrifugal pump.
Background technology
The practical disadvantage of centrifugal pump is exactly to be required for filling pump every time, and drain operation program is complicated, is unfavorable for realizing certainly
Dynamic control, employ many methods for this prior art and solve, but it is mostly complicated, and cost is high.
The content of the invention
The shortcomings that in order to overcome prior art, the utility model technology provide a kind of automatic priming device of centrifugal pump, and it is tied
Structure is simple, and cost is low, and automaticity is high.
The technical scheme in the invention for solving the technical problem is：Fixed water inlet pipe is sealed on centrifugal pump and is gone out
Sealed and connect electronic by tank pump line on the outlet pipe at water pipe, outlet pipe concatenation non-return valve and main valve, non-return valve and main valve both ends
Fill pump valve；One end of the fixed bleeder pipe communicated therewith is sealed on described water inlet pipe, the other end of bleeder pipe fixes electronic put
Air valve, the position of electronic vent valve are higher than described centrifugal pump；The control of described electronic filling pump valve, electronic vent valve and centrifugal pump
Device electrical connection processed.
The utility model is simple in construction, and cost is low, and automaticity is high.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model schematic diagram.
Embodiment
As shown in figure 1, sealing fixed water inlet pipe 11 and outlet pipe 1 on centrifugal pump 10, outlet pipe 1 concatenates non-return valve 3 and master
Sealed on the outlet pipe 1 at valve 2, non-return valve 3 and the both ends of main valve 2 by tank pump line 4 and connect electronic filling pump valve 6；Described water inlet pipe
One end of the fixed bleeder pipe 9 communicated therewith is sealed on 11, the other end of bleeder pipe 9 fixes electronic vent valve 8, electronic vent valve
8 position is higher than described centrifugal pump 10；The control device electricity of described electronic filling pump valve 6, electronic vent valve 8 and centrifugal pump 10
Connection.
Described both ends of motor-driven valve 6 simultaneously connect hand-operated valve 5.
Water outlet detection means 7 is fixed on the exhaust outlet of the electronic vent valve 8.
Described water outlet detection means 7 electrically connects with the control device of described centrifugal pump 10.
When centrifugal pump 10 needs to start, electronic filling pump valve 6 and electronic vent valve are opened by the control device of centrifugal pump 10
8, water water conservancy diversion fills pump in outlet pipe 1, after water outlet detection means 7 detects water outlet, illustrates that centrifugal pump 10 has been filled, centrifugal pump 10
Control device close electronic filling pump valve 6 and electronic vent valve 8 automatically.The can of centrifugal pump 10 starts.
