Preferably, also comprise steel support, described steel support is fixedly connected on the below of reducer union; Described steel support is fixedly linked by anchor bolt and the reinforcing bar be embedded in concrete bed.
Preferably, described reducing steel tube segment length changing value is not less than 10 with the ratio of corresponding diameter increm ent, and described reducing steel tube segment length is not less than 150mm.
Preferably, described reducer union internal surface is provided with interior corrosion-proof ring oxygen coating.
Preferably, described reducer union outer surface is provided with external galvanized layer layer.
The beneficial effect of the utility model preferred embodiment is: 1, the straight steel pipe section identical with valve internal diameter has been used in reducer union of the present utility model, solves the valve the problems of application caused because HDPE internal diameter of the pipeline is little in prior art Placement; And the transition of caliber is carried out by reducing steel tube section, compared to the caliber cataclysm that former Placement causes, steel reducer union makes the change of internal diameter of the pipeline more smooth-going, decreases local head loss and current to the impact of valve joint; The contact width of flange root and flange plate strengthens, and well solves shear strength deficiency and waterstop sealing problem; 2, arrange steel support bottom steel reducer union to be connected with base, by the weight transmitting of steel reducer union to base, change in original Placement, born the weight of HDPE pipe side flange by valve bolt; 3, the utility model adopts steel reducer union, and the stress condition of valve bolt can be made better, increase the service life, the seal of connection is better, more convenient laborsaving when installing simultaneously.

Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.
High density polyethylene (HDPE) aqueduct need be connected with the equipment such as valve, slip joint, steel pipe and pipe fitting, and this explanation is for the connection of high density polyethylene (HDPE) aqueduct and valve.As shown in Figure 1, Placement conventional is at present enclosed within the first steel flanges 4 on high-density polytene pipeline by one to be connected with the second steel flanges 5 of valve 3 body, realizes sealing by compressing high density polyethylene pipe flange root 2.The manufacturing of current valve matches with steel pipe, and the high density polyethylene pipe internal diameter of same size is compared little with steel pipe with valve, as shown in Figure 1, if high density polyethylene pipe and valve directly adopt Flange joint, likely cause butterfly valve plate not open completely, the operation of unfavorable pipe-line system, increase the problems such as local head loss.
In addition, according to the link position of Fig. 1 medium high density polyethylene pipe 1 with the second steel flanges 5 of valve 3 body, high density polyethylene pipe flange root 2 is subject to the shearing of the second steel flanges 5 and the first steel flanges 4 fastening force, affects structural safety.And high density polyethylene pipe flange root 2 is little with the second steel flanges 5 contact width of valve 3 body, unfavorable waterstop sealing.This structure is particularly evident for large diameter high density polyethylene pipe impact.
As shown in Figures 2 and 3, the reducer union of connection high density polyethylene pipe of the present utility model and valve, by steel flanges, steel pipe and steel support 10 3 part form.The steel pipe of reducer union comprises straight steel pipe section 6 and reducing steel tube section 7, and reducing steel tube section 7 one end internal diameter is identical with straight steel pipe section 6, and along with reducing steel tube section 7 extends, reducing steel tube internal diameter reduces gradually or increases to identical with connected high density polyethylene pipe 1 internal diameter; Straight steel pipe section 6 internal diameter is identical with the internal diameter of connected valve 3, and straight steel pipe section 6 length is normally used depending on connected valve 3 and required; Reducing steel tube section 7 length varying value is not less than 10 with the ratio of corresponding diameter increm ent, and reducing steel tube section 7 length is not less than 150mm; Reducer union is connected with high density polyethylene pipe 1 by the 3rd steel flanges 8, fastening by the first steel flanges 4 be socketed on high density polyethylene pipe; Be connected with the second steel flanges 5 of valve 3 body by the 4th steel flanges 9; 3rd steel flanges 8 is identical with high density polyethylene pipe 1 internal diameter, and the 4th steel flanges 9 is identical with valve 3 internal diameter.
Steel support 10 of the present utility model is fixedly connected on the below of reducer union, steel support 10 is for the connection of steel reducer union and concrete bed 12, steel support 10 is made up of Plate Welding, steel plate providing holes hole, bottom, be connected with the embedded bar 13 inlayed in concrete bed 12 by anchor bolt 11, steel support 10 and steel reducer union adopt welding manner to be connected.
Reducer union internal surface is provided with interior corrosion-proof ring oxygen coating, and reducer union outer surface is provided with external galvanized layer layer.It is anticorrosion that steel flanges and steel support can adopt hot galvanizing to carry out, and preventing external corrosion of steel pipe can adopt hot galvanizing, the nontoxic epoxy coating of interior anticorrosion employing.
The working principle of steel reducer union of the present utility model is: utilize the straight steel pipe that one section of internal diameter is identical with valve 3 internal diameter, makes valve can open and close smoothly.And by one section of reducing steel tube, the internal diameter between high density polyethylene pipe 1 and valve 3 is changed more smooth-going, solve all kinds of problems of the 3rd steel flanges 8 and the little initiation of flange root 2 contact width simultaneously.In addition, arrange steel support 10 bottom steel reducer union, make the bolt strained condition of steel reducer union and valve attachment portion better, sealing is tighter, and more convenient when installing.
