Description

A kind of transition Taper Pipe reinforced structure

Technical field

The utility model relates to water conservancy and hydropower technical fields, more particularly to one kind to be used for hydropower station pressure pipeline bifurcated pipe hydraulic pressure The transition Taper Pipe reinforced structure of test.

Background technique

With the continuous development of material industry, power station is investment reduction, more and more uses central water supply or grouping Supply water, bifurcated pipe using more and more extensive.For saving steel, reduce manufacture difficulty, reduction head loss, optimization flow-shape And whole stress condition etc., it generally requires and carries out the water pressure test before bifurcated pipe comes into operation, to examine bifurcated pipe quality, verifying to set Meter, while reducing or eliminating generated residual stress in bifurcated pipe forming process, it is ensured that bifurcated pipe operates normally in engineering.Bifurcated pipe It generally requires before the test and transition cone is set between bifurcated pipe and test bulkhead, and existing transition cone is generally using small as far as possible Half cone-apex angle does not have to transition cone, avoids excessive turning angle, generates excessive stress and concentrate, to meet the bifurcated pipe water pressure test Needs.But since half cone corner angle is smaller, the length for causing transition cone to prolong axis is too long, steel plate materials required for transition is bored More, the test site needed is larger, to increase experimentation cost.

Utility model content

To overcome existing transition to bore above shortcomings, the technical problem to be solved by the utility model is to provide one The reinforced structure that kind is arranged on the transition Taper Pipe of larger half cone-apex angle.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of transition Taper Pipe reinforced structure, two bifurcated pipe branch pipes for being responsible for the same end including being responsible for and being connected in bifurcated pipe by bifurcated pipe The free end of the three-way pipe structure of formation, the bifurcated pipe supervisor and bifurcated pipe branch pipe is equipped with test bulkhead, and the bifurcated pipe supervisor is remote One end from bifurcated pipe branch pipe is bored equipped with transition, and half cone-apex angle of the transition cone is 30~60 °, is responsible for phase in transition cone and bifurcated pipe Turning point even is equipped with reinforced structure, and the reinforced structure includes reinforcing beam and deep floor, and the reinforcing beam is vertically arranged in Between transition cone and bifurcated pipe supervisor, the deep floor is arranged in reinforcing beam two sides, and connects respectively with bifurcated pipe supervisor and transition cone It connects.

Further, the length of the reinforcing beam insertion bifurcated pipe supervisor is identical as exposed length.

Further, the deep floor includes multipair, and along bifurcated pipe supervisor's even circumferential setting.

The beneficial effects of the utility model are: boring semi-cone angle and benefit to transition by boring in design basis in conventional transition Strong structure improves and optimizes, using half cone-apex angle of wide-angle gradual change bore, and cone with silently and bifurcated pipe straight pipe transfer Place carries out structural strengthening, saves gradual change cone material more, the water pressure test place needed is smaller, this body weight of the bifurcated pipe water pressure test Lighter, the construction of gradual change cone is more convenient, quick, and the design of such channel design is more reasonable, and structure is simpler, is more suitable for The design of water pressure test temporary structure.

Detailed description of the invention

Label is that 1- bifurcated pipe is responsible in figure, 2- bifurcated pipe branch pipe, 3- test bulkhead, 4- transition cone, 5- reinforcing beam, and 6- reinforces Floor, half cone-apex angle of a-.

Specific embodiment

The present invention will be further described with reference to the accompanying drawing.

As shown in Figure 1, the utility model includes by bifurcated pipe supervisor 1 and two bifurcated pipe branch for being connected in 1 the same end of bifurcated pipe supervisor The free end of the three-way pipe structure that pipe 2 is formed, the bifurcated pipe supervisor 1 and bifurcated pipe branch pipe 2 is equipped with test bulkhead 3, the bifurcated pipe Be responsible for 1 one end far from bifurcated pipe branch pipe 2 and be equipped with transition cone 4, half cone-apex angle a of transition cone 4 is 30~60 °, transition cone 4 with Bifurcated pipe is responsible for 1 connecting place and is equipped with reinforced structure, and the reinforced structure includes reinforcing beam 5 and deep floor 6, and the reinforcing beam 5 is perpendicular Between transition cone 4 and bifurcated pipe supervisor 1, the deep floor 6 is arranged in 5 two sides of reinforcing beam for straight setting, and respectively with bifurcated pipe master 4 connection of pipe 1 and transition cone.

Traditional transition cone is generally bored using half cone-apex angle (being no more than 10 °) small as far as possible or without transition, is mainly Excessive turning angle is avoided, excessive stress is generated and concentrates, to meet the needs of the bifurcated pipe water pressure test.But due to half vertex of a cone Angle angle is smaller, and the length for causing transition cone to prolong axis is too long, and steel plate materials required for transition is bored are more, the test site needed Ground is larger, thus experimentation cost is higher.The utility model uses biggish half cone-apex angle a, it is possible to reduce transition cone 4 prolongs axis Length to save steel plate materials, but is concentrated, it is therefore desirable to be arranged in turning point and mend the disadvantage is that having larger stress in turning point Strong structure, which can dramatically increase the stability that transition cone 4 is connect with bifurcated pipe supervisor 1, to meet the bifurcated pipe water pressure test Force request.

For the ease of the stability that welding assembly and raising transition cone 4 are connect with bifurcated pipe supervisor 1, the reinforcing beam 5 is inserted The length for entering bifurcated pipe supervisor 1 is identical as exposed length.

Further, the deep floor 6 includes multipair, and is responsible for the setting of 1 even circumferential along bifurcated pipe.Since bifurcated pipe is responsible for 1 is relatively large in diameter, so the quantity of deep floor 6 is more, can more improve the stability of connection.

The utility model bores semi-cone angle to transition and reinforced structure improves by boring in design basis in conventional transition And optimization, using half cone-apex angle of wide-angle gradual change bore, and cone with silently and bifurcated pipe straight pipe turning point carry out structural strengthening, Save gradual change cone material more, the water pressure test place needed is smaller, this body weight of the bifurcated pipe water pressure test is lighter, and gradual change cone is applied Work is more convenient, quick, and the design of such channel design is more reasonable, and structure is simpler, is more suitable for the water pressure test and temporarily ties Structure design, has good practicability and application prospect.
