Examples
As shown in fig. 1-2, the novel composite air valve well for the large-caliber water pipeline comprises a main water pipeline 1 and a well chamber 2 arranged on the main water pipeline 1, wherein an air valve 3 is arranged in the well chamber 2, and the air valve 3 is connected with the main water pipeline 1 through a water branch pipe 4.
Specifically, the outer wall of the main water pipe 1 is provided with the concrete envelope 5, the main water pipe 1 can be reinforced by the envelope 5, and because the main water pipe 1 is generally located underground, the outer wall of the well chamber 2 and the periphery of the main water pipe 1 are covered with soil, so that the bottom of the well chamber 2 can be stably placed by using the main water pipe 1 with a large caliber as a support part, that is, the bottom of the well chamber 2 is placed on the envelope 5 on the outer wall of the main water pipe 1.
2 tops of well room are equipped with manhole 21 and sump pit 24, and the maintainer can get into well room 2 through manhole 21 from the outside in order to overhaul equipment such as air valve 3, and the residual ponding at 2 tops of well room can be gathered to sump pit 24, avoids ponding large tracts of land to cover at 2 tops of well room to cause the influence to well room 2. The left side wall and the right side wall of the well chamber 2 are provided with vent holes 22, so that ventilation inside the well chamber 2 is realized. The inner side wall of the well chamber 2 is also provided with a ladder 23, and after an overhaul worker enters the well chamber 2 through the manhole 21, the overhaul worker can continue to visit the well chamber 2 along the ladder 23.
Further, the air valve 3 is arranged in the middle of the well chamber 2, so that the defect that air exhaust and air dissipation are unstable due to the fact that the air valve is close to the edge of the well chamber 2 is avoided. Air valve 3 below is connected with water delivery branch pipe 4 through mountings such as bolt, still is equipped with manual butterfly valve 7 on the water delivery branch pipe 4, under the condition that needs overhaul air valve 3, can close manual butterfly valve 7, so, can avoid because the water in the water delivery main pipe 1 continues to rise to air valve 3 department through water delivery branch pipe 4, the drawback that the maintainer is unfavorable for air valve 3 to overhaul appears.
Further, the water delivery branch pipe 4 is connected with the water delivery main pipe 1 through a three-way pipe 6, in order to ensure the water yield, two water outlets 11 are arranged on the outer wall of the water delivery main pipe 1, namely, two branch pipe ports of the three-way pipe 6 are respectively connected with the water outlets 11 of the water delivery main pipe 1, and the main pipe is connected with the tail end of the water delivery branch pipe 4.
The tail end of the water delivery branch pipe 4 is provided with a flange, and a main pipe of the three-way pipe 6 is detachably connected with the water delivery branch pipe 4 through the flange. When needs are managed 1 maintenance to the water delivery, close the valve on the outside water delivery is responsible for 1, the maintainer gets into well room 2 inside through the manhole 21 at 2 tops of well room, close behind the manual butterfly valve 7 with the flange on three-way pipe 6 and the water delivery branch pipe 4 throw off, and hang off air valve 3 and branch pipe whole from well room 2 from outside use tools, after not having unnecessary equipment in the well room 2, can be convenient for the maintainer to get into the water delivery through the delivery port 11 on the water delivery is responsible for 1 or the mouth of pipe of three-way pipe 6 and overhaul in being responsible for 1.
The utility model discloses compare in the advantage of traditional well room and be:
1. the aperture of the traditional water delivery main pipe is small, so the whole water delivery main pipe can be wrapped in the well chamber when the well chamber is built, but for the water delivery main pipe with a large aperture (such as a 3M aperture pipeline), if the design method of wrapping the pipeline by the well chamber is still adopted, the building cost of the whole well chamber is increased, and the occupied area of the well chamber is also large. The utility model discloses directly adopt and be responsible for 1 with the water delivery as the supporting part, do promptly and seal 5 on the water delivery is responsible for 1, then place well room 2 on sealing 5, can fix well room 2 on the water delivery is responsible for 1, so reduced well room 2's construction cost and area, and reduced that traditional well room 2 need be in the civil engineering input such as bottom plate, the bed course of being responsible for the bottom setting.
2. Traditional well room only sets up a manhole on the well room top to in can getting into the well room to overhaul equipment such as valve, but can't overhaul equipment such as water delivery person in charge, the utility model discloses water delivery person in charge is connected through three-way pipe 6 between 1 and the water delivery branch pipe 4, makes when needs are responsible for equipment such as 1 to the water delivery and maintain, can break off three-way pipe 6, can be responsible for 1 to the water delivery and maintain after hanging equipment such as air valve 3, water delivery branch pipe 4 from well room 2, maintenance process convenient and fast.
3. The air valve in traditional well room is direct to be responsible for with the water delivery and links to each other, because of lacking the cavity space of gas collection, has certain discount on exhaust effect, the utility model discloses increased water delivery branch pipe 4 between air valve 3 and water delivery person in charge 1, increased the space of gas collection, improved exhaust effect.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
