The utility model has the beneficial effects that

Gas-water mixer is connect, by air water by the utility model by setting gas-water mixer with compressor and drainpipe Mixer is placed in motor-pumped well, and by injecting a large amount of pressure-air into gas-water mixer, pressure-air is formed in main pipeline High-pressure air-water mixture, high-pressure air-water mixture can be discharged to ground along drainpipe, thus draw water without water pump, by It is located at ground in compressor, also facilitates and compressor is overhauled.

The other end height of air inlet pipe is higher than the height of air inlet pipe one end, so that air inlet pipe is in obliquely, thus by gas When water mixer is put into motor-pumped well, a wedge angle is formed between air inlet pipe and main pipeline, facilitates the merging of steam heater.

The setting of shunt block, when pressure-air enters supervisor by air inlet and arrives interior, shunt block can be by the height Pressure air is divided into two strands, one is by upper exhaust outlet, and another stock is by lower exhaust outlet, logical by the pressure-air of upper exhaust outlet The water conservancy diversion for crossing cambered surface can be mixed with water upwards in main pipeline, and pass through pressure-air the leading by lower camber side of lower exhaust outlet Stream is mixed with water downwards in main pipeline, and reduction pressure-air flows downward in main pipeline in certain degree mixes with water Flow improve the effect of pressure maintaining to prevent pressure-air from flowing out by the lower end of main pipeline.

The setting of spiral thread also can be improved the effect of main pipeline pressure maintaining, prevent lower end of the pressure-air from main pipeline It leaks out.

The setting of annular grooving, when the upper end of drainpipe and main pipeline is attached fixed, on drainpipe can be equipped with The wiping ring that annular grooving matches is cooperated by wiping ring and annular grooving, to enhance the sealing of drainpipe Yu main pipeline junction Property.

Specific embodiment

Referring to Fig. 1 and Fig. 2, the utility model provides a kind of gas-water mixer, including vertical main pipeline 1 and air inlet pipe 2, air inlet is offered on the side wall of the main pipeline 1, and one end of the air inlet pipe 2 is connect with the air inlet, the air inlet Pipe 2 is straight tube, and the main pipeline 1 is vertically arranged, and the height of the other end of the air inlet pipe 2 is higher than the another of the air inlet pipe 2 The axis of the height at end, the axis of the air inlet pipe 2 and the main pipeline 1 is located in the same perpendicular, the air inlet pipe 2 Angle between the main pipeline 1 is 42 ° -48 °, and the lower end of the main pipeline 1 is angular cut, the upper end of the main pipeline 1 It is fixed with flange 4, the distance between the air inlet and 1 lower end of main pipeline are 0.5m-1.2m.

In actual use, compressor is set on the ground, and compressor passes through the air inlet pipe 2 of snorkel and gas-water mixer Connection, and the upper end of gas-water mixer is connected with one end of drainpipe 6, the other end of drainpipe 6 extends at ground, by carbonated drink Mixer is sent in motor-pumped well, and is embedded under the water level in motor-pumped well, and compressor is opened, and compressor passes through snorkel to carbonated drink Pressure-air is injected in mixer, pressure-air enters in main pipeline 1, and underground water is flooded in main pipeline 1, thus high pressure Air can be thoroughly mixed to form air-water mixture in the water in main pipeline 1, since main pipeline 1 is vertically arranged, in main pipeline 1, The lower local hydraulic pressure in position is higher, thus after pressure-air enters in main pipeline 1, impact force of the high pressure gas toward lower section It is influenced to slow down by hydraulic pressure, thus is formed by steam water interface can only outwardly flow out along main pipeline 1 and drainpipe 6 (being discharged from the free end of drainpipe 6).

It should be noted that due to the design that air inlet pipe 2 tilts upward, pressure-air enters supervisor to after interior, by The guide in the direction that air inlet pipe 2 drains, so that pressure-air (air-water mixture) can flow downward along main pipeline 1, and by water The influence of pressure, the limited length that pressure-air flows downward, the process that certain pressure-air flows downward are also to mix with water Process, so that it is sufficiently formed air-water mixture, and if the length of the main pipeline 1 on the downside of air inlet is shorter, it will may cause The situation that pressure-air is walked from the leakage of the lower end of main pipeline 1, and why be designed to tilt upward by air inlet pipe 2, it is in without designing (pressure-air is directly in main pipeline 1 to upper walking) diagonally downward, be because the inner wall of motor-pumped well usually has stone outstanding, When being put into gas-water mixer in motor-pumped well, it is possible to air inlet pipe 2 can be blocked, put so as to cause steam heater it is not in place, separately Outside, the connection snorkel of air inlet pipe 2 obliquely is upwardly extended connect with compressor, thus snorkel meeting wide-angle is turned round, and having can It can hinder the conveying of pressure-air.

And in order to solve the situation that pressure-air is walked from the leakage of 1 lower end of main pipeline, mainly by lengthening on the downside of air inlet The length of main pipeline 1, and the main pipeline 1 on the downside of air inlet is longer, in water level decreasing to when maintaining an equal level with air inlet, at this point, air inlet Water on the downside of mouthful cannot effectively drain.The length of the main pipeline 1 on the downside of air inlet should be thus reduced as far as possible.

The utility model also makees following improve:

It is fixed with shunt block 3 in one end of the air inlet pipe 2, the shunt block 3, the shunt block 3 is by air inlet One end of pipe 2 is divided into exhaust outlet and lower exhaust outlet up and down, and the upside of the shunt block 3 is acclivitous upper cambered surface, institute The downside for stating shunt block 3 is the lower camber side tilted down.

The setting of shunt block 3, in high pressure gas by being divided into two strands after shunt block 3, one by upper exhaust outlet (on Pressure-air), another is by lower exhaust outlet (lower pressure-air), and upper cambered surface tilts upward, thus upper pressure-air enters It walks directly up after in main pipeline 1, and lower high pressure gas enters lower walking backward in main pipeline 1, thus reduce in master To the total amount of the pressure-air of lower walking in pipeline 1, to reduce the probability that pressure-air is walked from the leakage of 1 bottom end of main pipeline.

It should be noted that due to the setting of shunt block 3, so that pressure-air is when by shunt block 3, high pressure Air opposite can be compressed, thus can increase the flow velocity of pressure-air (including upper pressure-air and lower pressure-air), thus Pressure-air may make more fully to mix with water.

Another way offers spiral thread on the inner wall of the main pipeline 1 on the downside of the air inlet.

After pressure-air proceeds in main pipeline 1, pressure-air is walked downwards, the meeting of pressure-air in main pipeline 1 Wall contact, the lines of spiral can hinder pressure-air to walk downwards, thus opposite pressure-air can be prevented from the lower end of main pipeline 1 Leakage.

Of course for processing is facilitated, spiral thread can be opened up on the inner wall of entire main pipeline 1, only air inlet top Spiral thread does not work.

Drainpipe 6 is connect with 1 upper end of main pipeline need to guarantee its leakproofness.

The upper end of the main pipeline 1 offers annular grooving 5, the upper surface of the annular grooving 5 and the main pipeline 1 Upper surface flushes, and the axis of the annular grooving 5 and the axis of the main pipeline 1 are on same straight line, the annular grooving 5 It is not connected to the inner wall of the main pipeline 1.

It can be thus equipped in the lower end of drainpipe 6 and wipe ring 7, be inserted into grooving by wiping ring 7, in drainpipe 6 and supervisor After road 1 connects, enhance its leakproofness.

Other settings:

Angle between the air inlet pipe 2 and the main pipeline 1 is 45 °, the air inlet and 1 lower end of main pipeline it Between distance be 1m.

The internal diameter of the main pipeline 1 is 30-50mm, and the internal diameter of the air inlet pipe 2 is 10-15mm.
