Technical field
The utility model relates to a kind of hydraulic test of pipeline welded type closure plates, belong to pipeline hydraulic pressure structure for pressure test technology neck
Domain.
Background technique
In recent years, solar light-heat power-generation is developed rapidly as a kind of emerging solar energy generation technology.For
Slot type photo-thermal power station, conduction oil are a kind of very important heat transfer mediums, and heat conducting oil pipe often uses big-diameter pipeline (pipeline
Outer diameter > 1000mm).For the pipeline of so Large Diameter Pipeline, when the water pressure test, according to conventional downhand welding closure plate, it is easy to appear rigidity
Not enough, the problems such as weld cracking, cause the water pressure test that can not carry out.And have to the thickness for increasing steel plate to improve rigidity,
Pipe diameter is bigger, and blind flange force is higher when the water pressure test, it is desirable that closure plate thickness is bigger, and the closure plate wall thickness often calculated exceeds
The thickness specification of conventional steel sheet product, needs specific customization, considerably increases purchase cost and difficulty.
Utility model content
The purpose of the utility model is to provide a kind of hydraulic test of pipeline welded type closure plate, especially a kind of solar energy optical-thermal
Power station heat conducting oil pipe water pressure test welded type closure plate.
To achieve the goals above, the technical solution adopted in the utility model is:
A kind of hydraulic test of pipeline welded type closure plate, including being welded on the outer ring of pipe end and being welded in outer ring
Closure plate；The end face setting reinforcing ring of the closure plate and several reinforcing floors, described reinforcing floor one end and reinforcing ring welding connect
It connects the other end to be welded and fixed with outer ring, reinforces floor and be evenly arranged along outer ring inner wall at radial pattern；The internal diameter of outer ring and pipeline and
Wall thickness is identical.
Technical solutions of the utility model further improvement lies in that: outer ring is identical as the material of pipeline.
Technical solutions of the utility model further improvement lies in that: closure plate is welded on inside outer ring using double groove.
Technical solutions of the utility model further improvement lies in that: between outer ring and pipeline use U-shaped or double V-groove pair
Weldering.
Technical solutions of the utility model further improvement lies in that: the internal diameter of reinforcing ring be closure plate diameter 1/4~1/3.
Technical solutions of the utility model further improvement lies in that: reinforce floor be arranged 6~12.
By adopting the above-described technical solution, the technical effect that the utility model obtains has:
The utility model is arranged outer ring and carries closure plate, using reinforcing annular ring and at the reinforcing floor of radial pattern arrangement welding
It matches, is welded in inner ring wherein reinforcing floor inner end, outer end is welded on outer ring, can effectively improve closure plate rigidity.
In the utility model using and test pipe same material, it is isometrical, etc. wall thickness a segment pipe it is stifled as the water pressure test
The outer ring of plate increases the weld strength with process pipe using U-shaped or double V-groove and process pipe butt welding.Closure plate is welded on
It inside outer ring, is welded using double groove, increases the weld strength of closure plate.
Reinforcing ring and the uniform force that can guarantee closure plate at several reinforcing floors of radiation profiles, mention in the utility model
The rigidity of high closure plate, reduces closure plate thickness, and the safety of guarantee test and accurate.
The utility model structure is simple, closure plate good rigidity, can reuse, have good comprehensive service performance.

Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further details the utility model:
It the utility model discloses a kind of hydraulic test of pipeline welded type closure plate, is made when carrying out the water pressure test to pipeline
?.The closure plate is particularly suitable in the solar energy thermo-power station heat conducting oil pipe water pressure test.Here is specific embodiment:
Hydraulic test of pipeline welded type closure plate in the utility model, as shown in Figure 1, including being welded on the outer of pipe end
Ring 1 and the closure plate 2 being welded in outer ring 1.Outer ring 1 is usually one section of outer ring cylinder pipe, the internal diameter and wall of outer ring 1 and pipeline
It is thick identical.When in use, outer ring 1 is welded on to the end of pipeline, due to closure plate 2 presence can by the closed at one end of pipeline,
To carry out the water pressure test.Preferential in specific implement, outer ring 1 is identical as the pipe material that needs are tested also, internal diameter
It is all the same with wall thickness.Usually, lower section of pipe cutting needs tested, is then arranged closure plate in pipeline.
As shown in Figure 1, Figure 2, Figure 3 shows, closure plate 2 is welded on inside outer ring 1, if closure plate 2 an end face setting reinforcing ring 3 and
It is dry to reinforce floor 4, for reinforcing to closure plate 2, improve the rigidity of closure plate 2.It reinforces 4 one end of floor and the welding of reinforcing ring 3 connects
It connects the other end to be welded and fixed with outer ring 1, reinforces floor 4 and be evenly arranged along 1 inner wall of outer ring at radial pattern.The setting of reinforcing ring 3 is stifled
The center of 2 end face of plate.Preferential, closure plate 2 is welded on inside outer ring 1 using double groove, specific as shown in Figure 3.In this way
It can guarantee the firm welding degree between closure plate 2 and outer ring 1.
In specific implement, the internal diameter of the reinforcing ring 3 in the utility model is the 1/4~1/3 of 2 diameter of closure plate.This reality
It is arranged 6~12 with the reinforcing floor 4 in novel.Reinforcing ring 3 at several reinforcing floors 4 of radiation profiles can guarantee closure plate
Uniform force, improve the rigidity of closure plate, the lesser closure plate of thickness can be used to meet test demand, and guarantee test
It is safe and accurate.
When in use, the outer ring 1 for being welded with closure plate 2 is welded on to the end for needing the pipeline tested.Outer ring 1 and pipeline it
Between generally use U-shaped or double V-groove butt welding.
The utility model use and test pipe same material, it is isometrical, etc. wall thickness a segment pipe as water pressure test closure plate
Outer ring the weld strength with process pipe is increased using U-shaped or double V-groove and process pipe butt welding.Closure plate is welded on outer
It inside ring, is welded using double groove, increases the weld strength of closure plate.
Closure plate is carried using outer ring in the utility model, can directly be cut outer ring from pipeline after use
Come, without destroying closure plate ontology, accomplish to reuse on pipeline cut surface progress slope is cut polishing and can also be welded to again,
The utilization rate of closure plate is improved, cost of use is reduced.
The utility model structure is simple, closure plate good rigidity, can reuse, have good comprehensive service performance.
