Abstract
The utility model relates to a diversion three-way pipe fitting which comprises a main pipe and a branch pipe, wherein the main pipe is provided with a passage, a through hole is formed at one side at the middle part of the passage, and the branch pipe is arranged on the through hole in a sealing way. The utility model is characterized in that a bent pipe is arranged at the inner side of the through hole of the main pipe, the upper end of the bent pipe is connected on the branch pipe, and the lower end of the bent pipe is positioned in the passage of the main pipe. Compared with the prior art, the diversion three-way pipe fitting has the advantages that the bent pipe for side flow is bent, and then, is inserted into a straight flow section of the main pipe, the overlarge excessive pressure energy of the near circulating pipelines of the branch pipe is used to divert the mediums of the far circulating pipelines of the branch pipe to commonly advance, in addition, the excessive pressure of the strong-pressure branch flow can be used to divert the weak-pressure branch flow to commonly advance. Simultaneously, water head loss can be increased to reduce the differential pressure formed by the far and near circulating pipelines.
Description
Technical field
The utility model relates to a kind of river diversion tee joint pipe fitting.
Background technique
Along with living standards of the people improve, types such as hotel, office building, high-grade apartment, hospital building adopts central heating system, and it requires more and more higher to the central heating system delivery quality.The return pipe net of traditional hot-water heating system, as shown in Figure 1, comprise elevated tank 2a, heater 3a, be responsible for pipeline 5a, arm pipeline 6a and recycle pump 4a, elevated tank 2a is provided with heater 3a with the connecting pipeline of being responsible for pipeline 5a, be responsible for pipeline 5a and surround a loop, recycle pump 4a then is positioned on this loop, arm pipeline 6a is a plurality of and is connected in parallel with each other, and be connected on person in charge's pipeline 5a by a plurality of river diversion tee joint pipe fitting 1a, as shown in Figure 2, each river diversion tee joint pipe fitting 1a comprises person in charge 11a and arm 12a, person in charge 11a has a passage and middle part one side offers a through hole, arm 12a then is located on the through hole hermetically, common arm 12a be responsible for the 11a part that is formed in one.There is following defective in the hot-water heating system of this line arrangement, nearly arm pipeline (promptly near water pump) with big overbottom pressure goes into to be responsible for pipeline by the tee pipe fitting backlash, simultaneously will stop that remote branch of a clan pipe pipeline (promptly away from water pump) current are by the mouth that crosses, thereby cause nearly arm circulation loop flow excessive, and remote branch of a clan pipe circulation loop flow is too small even be zero disadvantage.
For solving this technical problem, the designer reduces the caliber of nearly arm pipeline traditionally as far as possible, or suitably amplify the caliber of arm pipeline, because the circular flow away from the remote branch of a clan pipe circulation loop of water pump is too little, the water outlet of hot water water distribution tap is very cool, and the user will bleed off the lower cold water of many water temperatures in vain could satisfy the requirement of water outlet water temperature.The valve opening degree of utilizing on the arm pipeline is also arranged, regulate flow, turn down the valve on the nearly arm pipeline, can increase its loss of head, to reduce the formed pressure reduction of far and near arm circulation loop.Basically, it is to be cost to consume excess energy, tries to achieve the balance of flow.Simultaneously, the valve opening degree is difficult to grasp, and closes minor valve and causes pipeline blockage easily, wastes energy.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of river diversion tee joint pipe fitting that can dredge current at the above-mentioned state of the art.
Another technical problem to be solved in the utility model provides a kind of river diversion tee joint pipe fitting that can reduce far and near circulation loop pressure reduction.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of river diversion tee joint pipe fitting, comprise and being responsible for and arm, the aforesaid person in charge has a passage and middle part one side offers a through hole, aforesaid arm then is located on the aforesaid through hole hermetically, the through hole inboard that it is characterized in that the described person in charge is provided with a bend pipe, described arm is accepted in this bend pipe upper end, and the lower end is positioned at the described person in charge's passage.
As preferably, the bore of described arm is less than the bore of being responsible for, and described bend pipe internal diameter is less than a bore.
Further, the described person in charge is positioned at the annulus portion that arm is stretched in through hole periphery formation one, because of this annulus portion makes the bend pipe internal diameter less than a bore.
The female end diameter of arm is littler than the female end diameter of being responsible for, and the female end diameter of bend pipe is littler than the female end diameter of arm.
Make for convenient, the described person in charge, arm and bend pipe are to each other by the one that is welded.
Compared with prior art, advantage of the present utility model is: bend pipe inserts the direct current section of being responsible for after turning round as effluent, it can utilize the excessive overbottom pressure energy of nearly arm circulation loop, dredge remote branch of a clan pipe circulation loop medium and advance jointly, the change negative factor is active factor, has not only overcome original circuit defective, and again because the setting of bend pipe, its water (flow) direction is in full accord with the interior direct current section of the person in charge, makes the overbottom pressure of suppressing the tributary can be used to dredge the weak tributary of pressing and advances jointly, plays guide functions.By the active and static pressure conversion, strong and weak tributary is mutual water conservancy diversion relation all the time, also increases its loss of head simultaneously, to reduce the effect of the formed pressure reduction of far and near circulation loop.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 3, hot-water heating system comprises elevated tank 2, heater 3, is responsible for pipeline 5, arm pipeline 6 and recycle pump 4, elevated tank 2 is provided with heater 3 with the connecting pipeline of being responsible for pipeline 5, be responsible for pipeline 5 and surround a loop, recycle pump 4 then is positioned on this loop, arm pipeline 6 is for a plurality of and be connected in parallel with each other, and is connected in by a plurality of river diversion tee joint pipe fittings 1 and is responsible on the pipeline 5, and each arm pipeline 6 is provided with valve.
As shown in Figure 4, each river diversion tee joint pipe fitting 1 comprises the person in charge 11 and arm 12, the person in charge 11 has a passage (claiming the direct current section again) and middle part one side offers a through hole, arm 12 then is located on the through hole hermetically, and the person in charge 11 through hole inboard is provided with a bend pipe 14, and arm 12 is accepted in these bend pipe 14 upper ends, the lower end is positioned at is responsible for 11 passage, the overbending direction of bend pipe 14 is consistent with water (flow) direction, plays guide functions, and the bore of arm 12 is less than the bore of being responsible for.Bend pipe 14 internal diameters are less than arm 11 internal diameters.Be responsible for 11 and be positioned at the annulus portion 13 that arm is stretched in through hole periphery formation one, because of this annulus portion 13 makes bend pipe 14 internal diameters less than arm 12 internal diameters.The person in charge 11 in the present embodiment, arm 12 and bend pipe 14 are to each other by the one that is welded, all adopt stainless steel to make, wherein the female end diameter d 2 of arm is littler more than No. one than the female end diameter d of being responsible for 1, and the female end diameter d 3 of bend pipe is littler No. two than the female end diameter d 2 of arm.
