Description
Technical field
The utility model relates to municipal works field, specifically a kind of water supply line automatic exhaust device under water.
Background technology
For a long time, how solving the vapour lock problem of the upper and lower fluctuating section of water supply line (or under riverbed) under water, is a large technical barrier of puzzlement world engineering technological all the time.Automatic (suction) air bleeding valve that state, inside and outside all relevant manufactures are manufactured, because structure and venting principleand make so, can only work in normal pressure atmospheric environment, can not be arranged in water or in soil and use.
For getting around above-mentioned technical barrier in engineering practice, the process of the force pipe that crosses the river is taked usually to the flexible mode of level (or straight ascent) stringing, be intended to avoid the air because dissolving in Pipeline Water to discharge because of the change of the condition such as pressure, temperature, and be gathered near pipeline local high spot and form block water air bag (band), i.e. so-called " vapour lock ".The existence of pipeline vapour lock, will have a strong impact on conveyance power of water and the security of operation of pipeline, and operation energy consumption also significantly increases thereupon and cannot solve.
The advantage of above-mentioned conventional method is that venting principleand is feasible, and exhaust measure is easy, reliable, and difficulty of construction is general, can be widely used in the comparatively smooth riverbed of underwater topography; But shortcoming is also apparent, is namely difficult to the riverbed that adaptation to the ground fluctuations is larger.During Practical Project is built, the position of river crossing is often specified by the department such as navigation channel and water conservancy, and the section face in the riverbed that crosses the river is single-stage or multistage hump shape.If still adopt conventional method to go design and construction in this case, the needs that lay of overwhelming majority pipeline deep-cut, buriedly (but to have no way out, pipe top must fall within the following certain distance of riverbed minimum point), under water the fluting section of pipe laying must put more greatly, more slow could the lower pipe of safety and lower diver, difficulty of construction height is not said, trench backfill quality is also difficult to control, and construction costs is high especially.
Utility model content
The utility model, for the deficiencies in the prior art, creatively devises a kind of water supply line automatic exhaust device under water, and structure is succinct, and runnability is stablized, and reliability is high.
The technical solution of the utility model: a kind of water supply line automatic exhaust device under water, comprise water supply line, it is characterized in that: in the middle of described water supply line, be provided with gas collection threeway, gas collection threeway is connected by ring flange with between water supply line, the upper end of gas collection threeway is connected with air reservoir by ring flange, automatic exhaust steam valve is disposed with from top to bottom in air reservoir, manual service valve and the gas-water continuous be connected with gas collection threeway are taken over, blind plate is fixed with by ring flange on the top of air reservoir, air reservoir is provided with the air discharge guiding pipe be connected with the external world.
Water supply line, gas collection threeway, air reservoir are the metal or non-metal pipe that meet intensity and anticorrosion requirement.
The diameter of the upper end open of gas collection threeway is identical with the diameter of air reservoir.
The nominal diameter of gas collection threeway and air reservoir can be identical or different with the nominal diameter of water supply line.
Technique effect of the present utility model:
1, all parts all adopt existing state tender, are easy to processing and manufacturing, and have ripe technical standard;
2, (than the gross investment of cross river pipeline, almost can ignore) cheap for manufacturing cost, construction and installation are easy, significantly can reduce buried depth of pipeline, and construction investment lays the investment of similar pipeline under being greatly better than plane bed landform, remarkable in economical benefits;
3, this device structure is succinct, and runnability is stablized, and reliability is high;
4, the automatic exhaust steam valve in device can accomplish on-bne repair or replacing, does not affect the normal operation of water supply line between turn(a)round.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Number in the figure represents respectively: 1-water supply line, the threeway of 2-gas collection, 3-ring flange, 4-air reservoir, 5-manual service valve, 6-automatic exhaust steam valve, and 7-gas-water continuous is taken over, 8-blind plate, 9-air discharge guiding pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in Figure 1, a kind of water supply line automatic exhaust device under water, comprise water supply line 1, it is characterized in that: in the middle of described water supply line 1, be provided with gas collection threeway 2, be connected by ring flange 3 between gas collection threeway 2 with water supply line 1, the upper end of gas collection threeway 2 is connected with air reservoir 4 by ring flange 3, automatic exhaust steam valve 6 is disposed with from top to bottom in air reservoir 4, manual service valve 5 and the gas-water continuous adapter 7 be connected with gas collection threeway 2, blind plate 8 is fixed with by ring flange 3 on the top of air reservoir 4, air reservoir 4 is provided with the air discharge guiding pipe 9 be connected with the external world.
Water supply line 1, gas collection threeway 2, air reservoir 4 are the metal or non-metal pipe that meet intensity and anticorrosion requirement.
The diameter of the upper end open of gas collection threeway 2 is identical with the diameter of air reservoir 4.
The nominal diameter of gas collection threeway 2 and air reservoir 4 can be identical or different with the nominal diameter of water supply line 1.
Use water supply line under water after automatic exhaust device, after bubble in water supply line is collected by gas collection threeway, enter in air reservoir through gas-water continuous adapter, perform exhaust event by automatic exhaust steam valve, the gas of discharging through automatic exhaust steam valve is accessed in normal pressure atmospheric environment by air discharge guiding pipe again.When automatic exhaust steam valve breaks down or overhaul time, manual service valve can be closed and carry out attended operation.
A kind of water supply line of the present utility model automatic exhaust device under water, all parts all adopt existing state tender, are easy to processing and manufacturing, and have ripe technical standard; (than the gross investment of cross river pipeline, almost can ignore) cheap for manufacturing cost, construction and installation are easy, significantly can reduce buried depth of pipeline, and construction investment lays the investment of similar pipeline under being greatly better than plane bed landform, remarkable in economical benefits; This device structure is succinct, and runnability is stablized, and reliability is high; Automatic exhaust steam valve in device can accomplish on-bne repair or replacing, does not affect the normal operation of water supply line between turn(a)round; Thoroughly solve long distance, all kinds of bore water supply line under complicated underwater topography environment, at the exhausting problem in river (river, lake), highly widely popularize and apply.
