Above-mentioned well sealing Water supply device, described water pipe, its body that is arranged in air bag is provided with the uniaxial pressure limiting valve, and the top cylinder of described air bag 1 covers and is provided with pressure limiting valve.
Above-mentioned well is with sealing Water supply device, and the tube circle interlude of described air bag is a soft rubber ring wall section.
Above-mentioned well seals 11 with sealing Water supply device, the wedge angle that the last cover periphery of described air bag has wedge shape to extend.
Above-mentioned well is with sealing Water supply device, and the lower end of described water pipe has flange, and the upper end has suspension ring.
The utlity model has following characteristics:
1. air bag is adhered on the water pipe, water pipe is connected in the outlet pipe of pump, expanding by airbag aeration intercepts the atmospheric pressure effect in the sealing well, makes the water burst of motor-pumped well be able to carry out under negative pressure state, efficiently solves the problem that motor-pumped well water yield under the atmospheric pressure effect is little and can't effectively improve;
2. air bag is inserted on the water pipe easily by the plug-in mounting mouth of pipe, can utilize pipe collar on the plug-in mounting mouth of pipe to realize sealing between the plug-in mounting mouth of pipe and the water pipe easily;
3. can prevent that cover capsule face pressurized from excessively outwards expanding by the connecting lacing wire between the upper and lower cover;
4. when setting up the uniaxial pressure limiting valve on the outlet pipe, can introduce the press water that pump is discharged,, and can control the bulbs of pressure by pressure limiting valve by press water expansion utricule by the uniaxial pressure limiting valve;
5. can enclose interlude by tube is that the design of soft rubber ring wall section realizes the sealing between capsule tube and the more coarse well internal face, raising negative-pressure vacuum degree;
6. the wedge angle sealing cut-out pressure air that can utilize end periphery on the capsule tube further improves the hermetic barrier performance by penetrating into that little concavo-convex slit on the rough surface in the well is located;
7. scientific structure design is easy, is easy to install on the delivery port of pump;
Adopt the utility model can make the motor-pumped well of numerous water yield depletion recover vitality again, avoid digging a well again, can therefore save a large amount of well-digging funds and labour; Simultaneously, the motor-pumped well to normal use can reach energy-conservation and protective effect; The construction of farm irrigation facility etc. is safeguarded to have outstanding progressive meaning.
Description of drawings
Fig. 1 is the utility model structural representation.
The component label is respectively in the accompanying drawing: 1-air bag, 2-water pipe, 3-pore, 4-plug-in mounting mouth of pipe, 5-pipe collar, 6-connecting lacing wire, 7-be anti-raises one's hat, 8-uniaxial pressure limiting valve, 9-pressure limiting valve, 10-soft rubber crusty pancake circle section, the sealing of 11-wedge angle, 12-flange, 13-borehole wall, 14-electric wire, 15-air inlet pipe, 16-suspension ring.
