Description
Technical field
The utility model relates to a kind of novel evacuated diversion supply equipment, especially relates to a kind of supply equipment with self-suction function.
Background technology
Because pump house environment and geographical position limit, a lot of supply equipment import all adopts the mounting means sucted, in negative pressure conventional at present, water form or scheme mainly contain submersible pump, submerged pump (axial-flow pump), self priming pump, installation bottom valve, join vacuum water diversion pump etc., but it is little that this several form all exists capacity, thus go up the shortcomings such as the water time is long, water supply flow is little, startup water discharging time is long.At some large discharge, there is the suction line of longer level, have certain suction head and require to start the short water supply occasion (as fire-fighting watering equipment) of water discharging time, current suct mounting means and obviously can not meet instructions for use.
Utility model content
The purpose of this utility model is that providing a kind of can meet the heavy caliber suction line that some have longer level, and has certain suction head, the vacuum water diversion supply equipment simultaneously requiring again device start water discharging time short.
In order to solve the problems of the technologies described above, the utility model vacuum water diversion supply equipment, comprising: vacuum diversion volume, in the import department of described vacuum diversion volume, vacuum control check valve and water source probe is housed; Main pump, is equipped with the first electromagnetic valve at the outlet at bottom place of described vacuum diversion volume, and the water inlet of described main pump is connected with the outlet of described vacuum water diversion pot bottom; Threeway, the first end of described threeway is connected with the outlet pipeline of described main pump, and the second end of described threeway is connected with vibration means for main pipe for supplying water road by the second electromagnetic valve; Buffering exhaust tank, described buffering exhaust tank passes through the three-terminal link of the 3rd electromagnetic valve and described threeway, and described buffering exhaust tank is connected with the import department of described vacuum diversion volume by the 4th electromagnetic valve.
The position that described buffering exhaust tank is installed is higher than described vacuum diversion volume.
Described vacuum diversion volume is equipped with automatic air valve and float switch.
Described buffering exhaust tank is also provided with circulating exhaust device and liquid-level switch.
Described first electromagnetic valve is big caliber electromagnetic valve.
Large volume gas in suction line lower than Pump Suction Nozzle end can be discharged after the utility model vacuum water diversion supply equipment starts, negative pressure is formed rapidly in suction line, and then allow water be full of rapidly whole pump suction pipe road, reaching pump startup water discharging time is zero or extremely short, the object of rapid normal water supply.Equipment adopts Automatic Control, can join pump according to actual conditions, and according to the flow rate calculation selection buffering exhaust tank of pump and the volume of vacuum diversion volume.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model vacuum water diversion supply equipment is described in detail.
As shown in Figure 1, the utility model vacuum water diversion supply equipment, equipment suction line 15 is connected with vacuum diversion volume 4, in vacuum diversion volume 4 import department, vacuum control check valve 1 and water source probe 2 are housed, automatic air valve 5 and float switch 3 are housed above vacuum diversion volume 4, vacuum diversion volume 4 outlet at bottom is equipped with heavy caliber first electromagnetic valve 7, then be connected with main pump 12 water inlet, main pump 12 outlet pipeline is equipped with a point water threeway 14, second electromagnetic valve 13 of wherein leading up to is connected with vibration means for main pipe for supplying water road, the 3rd electromagnetic valve 11 of separately leading up to is connected with buffering exhaust tank 9 water inlet, buffering exhaust tank 9 is provided with circulating exhaust device 8 and liquid-level switch 10, wherein buffering exhaust tank 9 installation site should higher than vacuum diversion volume 4.
Before rigging up and debugging, in vacuum diversion volume 4, fill water.When equipment runs: open the first electromagnetic valve 7 and the 3rd electromagnetic valve 11, close the 4th electromagnetic valve 6 and the second electromagnetic valve 13, start main pump 12, water in vacuum diversion volume 4 is pumped to buffering exhaust tank 9 by main pump 12, gas in buffering exhaust tank 9 is discharged by circulating exhaust device 8, and the negative pressure that the water then in vacuum diversion volume 4 is pumped and is formed is filled being entered tank body by the gas in equipment suction line.When the liquid level in vacuum diversion volume 4 drops to float switch 3 low liquid level, close the first electromagnetic valve 7, 3rd electromagnetic valve 11 and the second electromagnetic valve 13, open the 4th electromagnetic valve 6, water in buffering exhaust tank 9 re-injects vacuum diversion volume 4, gas in vacuum diversion volume 4 is discharged by automatic air valve 5, when the liquid level in buffering exhaust tank 9 drops to liquid-level switch 10 low liquid level, close the 4th electromagnetic valve 6 and the second electromagnetic valve 13, open the first electromagnetic valve 7 and the 3rd electromagnetic valve 11, water in vacuum diversion volume 4 is pumped to buffering exhaust tank 9 again, in vacuum diversion volume 4, form negative pressure again entered tank body to fill by the gas in equipment suction line, the like, repeatedly after circulation, suction line is all full of water, now water source probe 2 has detected that water passes through, provide signal at stop the 4th electromagnetic valve 6 and the 3rd electromagnetic valve 11, open the first electromagnetic valve 7 and the second electromagnetic valve 13, equipment just can normal water supply.Whole exhaust diversion process is very short, and the level that can realize is remote, the short time, big-flow self-priming feedwater.
Large volume gas in suction line lower than Pump Suction Nozzle end can be discharged after the utility model vacuum water diversion supply equipment starts, negative pressure is formed rapidly in suction line, and then allow water be full of rapidly whole pump suction pipe road, reaching pump startup water discharging time is zero or extremely short, the object of rapid normal water supply.Equipment adopts Automatic Control, can join pump according to actual conditions, and according to the flow rate calculation selection buffering exhaust tank of pump and the volume of vacuum diversion volume.
Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
