Abstract

The utility model provides a diverting three-way joint, which is composed of a vertical tube and a transverse tube which are mutually connected. The diverting three-way joint is characterized in that a transitional connecting portion of the vertical tube and the transverse tube is in bending transition with the bending direction identical to the return water direction in the transverse tube, or the transitional connecting portion is in inclination transition with the inclining direction identical to the return water direction in the transverse tube. The utility model has the advantages that 1) the diverting three-way joint overcomes unbalance of circulation flow in remote and near loops of each return water pipe of a copper hot water return pipe, 2) the diverting three-way joint is a single component product, utilizes the high-pressure bulging process in ordinary temperature as the main molding technique, which is simple in structure and reliable in quality, and moreover, the diverting three-way joint utilizes the mounting and connecting method (socket-joint and brazing connection) the same with that of a common three-way joint, thereby realizing reliable use quality.

Description

A kind of river diversion tee joint joint
Technical field
The utility model relates to a kind of river diversion tee joint joint, is used for each return riser of copper hot water backwater pipeline and crosses being connected of joint with the backwater main, belongs to water conservancy diversion joint technical field.
Background technique
Copper hot water backwater pipeline as shown in Figure 1, each return riser 2 and backwater main 3 traditional product that the joint is connected that crosses is common tee union 1.The structure of common tee union 1 is made up of with transverse tube 4 interconnective vertical tube 5 as shown in Figure 2, and its transition attachment portion is 90 degree right angles substantially, makes that the through hole between the transition attachment portion 6 is vertical with the direction of backwater, i.e. the direction of arrow in the transverse tube 4 among Fig. 2.
Because the backwater of water return pipeline threeway is to converge into one the tunnel again by the backwater of backwater main and the backwater both direction of return riser, when using common tee union, because the through hole between the transition attachment portion 6 of tee union is vertical with the direction of backwater all the time, can make the backwater of two-way form the current collision.As shown in Figure 1, in this pipe-line system, near-ring road near the cycling hot hydrophone, because the pressure of return water height (pressure loss is little) of return riser 2, collision influence to the backwater (pressure loss is big, and pressure is low) of backwater main 3 is big, has hindered the flow velocity of backwater main 3, make away from the backwater flow velocity of the loop far away of cycling hot hydrophone 9 slowly, cause the energy imbalance of circular flow in each return pipe great distance, the near-ring road.Since loop far away because of pipeline because of the flow velocity due to the pressure loss slow and heat dissipation greatly to have caused exporting water temperature low, add this obstruction influence, make that loop outlet water temperature far away is lower, and heat up slowly.
Usually take following measure at this pipeline: as take to strengthen dry tube diameter and make the flow velocity that slows down, water inlet caliber reduce gradually and return pipe measure such as strengthen gradually remedies far, the energy imbalance of circular flow in the near-ring road.But these measures all are to be cost to increase the pipeline cost and to increase the heat heat leakage.Along with growth in the living standard, also higher to the requirement of hot water service quality, be badly in need of a kind of solution fundamentally and corresponding product.
Summary of the invention
The purpose of this utility model is to eliminate the energy imbalance of circular flow in each return pipe great distance, the near-ring road, makes far away, near-ring way outlet water temperature become to being unanimity.
In order to achieve the above object, the technical solution of the utility model has provided a kind of river diversion tee joint joint, it is characterized in that, form by interconnective connecting tube and transverse tube, wherein, connecting tube is connected with transverse tube is vertical, and its side that is connected with the transverse tube outlet end becomes curve transition.
Further, the radius of curvature R of described curve transition is 1.0~1.5 times of through hole radius.
Another kind of technological scheme of the present utility model has provided a kind of river diversion tee joint joint, it is characterized in that, is made up of interconnective inclined tube and transverse tube, and wherein, inclined tube tilts to be connected with transverse tube, and its side that is connected with the transverse tube entrance point becomes 30~60 ° angle α.
It is parallel that the river diversion tee joint joint that the utility model provides makes the direction of through hole and backwater between the transition attachment portion turn round gradually from beginning vertical, realized avoiding the two-way backwater to form the phenomenon that current collide; Perhaps the direction of through hole between the transition attachment portion and backwater has also realized avoiding the two-way backwater to form the phenomenon that current collide at angle, and the high speed backwater has also produced guiding, quickened the effect of backwater in the backwater main in the return riser.
The structure of river diversion tee joint joint transition attachment portion has used for reference the product structure of drainage pipe similar applications and the rifle that sandblasts uses pressurized air stream to drive the principle that effect is hit in sand generation spray.This product is installed and used each return riser of hot water backwater's pipeline and the backwater main joint that crosses, except the return riser current can not collide backwater main current, also since return riser faster current can drive the backwater stream of backwater main, make it to quicken, further improved the energy imbalance of circular flow in each return pipe great distance, the near-ring road.
The utility model has the advantages that:
1) solves and improved the energy imbalance of circular flow in each return pipe great distance of copper hot water backwater pipeline, the near-ring road;
2) be single parts product, main moulding process adopts normal temperature inner high voltage bulging process, and is simple in structure, reliable in quality; Adopt the installation Placement the same with common tee union (socket joint soldering connection), service property (quality) is reliable.
