It sets up conical closure plate to cross to fix at the pipeline mouth of circulating line to the intensity of this closure plate has been strengthened through set up floor and angle rib board in bottom plate and toper shell, intensity when the closure plate of guaranteeing the large diameter pipeline receives higher pressure, and then the tightness when having guaranteed pipeline hydrostatic test.
Description
Technical field
The utility model relates to fuel-burning power plant circulating line technical field, particularly a kind of closure plate for the circulating line hydraulic testing.
Background technology
At home in engineering project implementation, after circulating water pipeline installation, general and owner and supervisor hold consultation, according to the scope of DLT869-2012 " fuel-burning power plant solder technology code " table 5 welding joint partition test, in method and ratio, the IIIth part describes: the vapour of working pressure 0.1MPa≤P≤1.6MPa, water, oil, feed channel, all welding joint outward appearances detect should carry out 100% self-inspection, 25% specially examines, Non-Destructive Testing is carried out again after passed examination, adopt wherein any one method of ray detection or ultrasound examination, amount detection is 1% of welding joint total quantity.5% of total quantity can be increased to, based on seam inspection test depending on owner and the maximum amount detection of supervision requirement.
Along with the raising of standard, the inspection of quality of DLT5210.5-2009 electric power construction and assessment routine the 5th part: pipeline and system requirements circulating water pipe need to carry out the hydraulic testing, and international pro-ject must carry out the hydraulic testing on request, the method for the hydraulic testing is replaced more and more not to be accepted for percentage of detection.
Especially for bigbore circulating line, the version of closure plate differs, and can affect the judgement of test findings.
Utility model content
For overcoming problems of the prior art, the utility model provides a kind of closure plate being applicable to heavy caliber circulating line, ensure that the tightness of circulating line during hydrostatic test, makes hydraulic testing shutoff simple and reliable.
The technical scheme in the invention for solving the technical problem is: this kind of circulating line hydraulic testing closure plate, it is characterized in that: comprise two ends and be uncovered conical shell, circular base plate is fixedly welded with at the opening end that conical shell is little, the uncovered diameter that circular base plate diameter is little with conical shell is identical, and base plate is by little for conical shell uncovered closed; Base plate is fixed near conical shell inner chamber side and is welded with floor very much; Be fixedly welded with the short tube of a circle at the opening end that conical shell is large, have angle side bracket at conical shell internal chamber wall and short tube soldered place one week uniform welding, outside short tube, be fixedly welded with stiffening ring; Short tube is fixed as one by welding and circulating line.
Further, the opening end diameter that described conical shell is large is 2400mm ~ 3200mm.
Further, described angle side bracket is triangular plate, and the both sides of triangular plate are welded on the large opening end inwall of conical shell and circular short tube inwall respectively.
Further, the weld seam between conical shell and base plate, short tube is closed weld seam.
To sum up, the beneficial effect of technique scheme of the present utility model is as follows:
By being fixedly installed the overall closure plate for taper in the pipeline opening of circulating line, prevent the concentrations of pressure during the hydraulic testing.And the intensity of this closure plate is strengthened by arranging floor and angle side bracket in base plate and conical shell, ensure the intensity when closure plate of large diameter pipeline is subject to elevated pressures, and then tightness when ensure that hydraulic test of pipeline.

Fig. 2 is cut-open view of the present utility model;
Fig. 3 is the structural representation of the utility model conical shell.
In figure:
1 conical shell, 2 short tubes, 3 base plates, 4 stiffening rings, 5 floors, 6 angle side brackets, 7 little opening ends, 8 large opening ends, the pipeline opening of 9 circulating lines.
Embodiment
Be described in detail to characteristic sum principle of the present utility model below in conjunction with accompanying drawing, illustrated embodiment, only for explaining the utility model, not limits protection domain of the present utility model with this.
As shown in Figure 1, this utility model comprises two ends and is uncovered conical shell 1, respectively by two of uncovered size definition conical shell uncovered be large opening end 8 and little opening end 7, as shown in Figure 3.Because this closure plate is mainly used in bigbore circulating line, flat closure plate lifting surface area is little, stressed concentrated, easily causes closure plate to destroy, does not have the effect of application.And the diameter smooth gradual change of conical shell, during as closure plate, lifting surface area is large, stressed can not concentrations, effectively ensure that the tightness of circulating line, serve the due effect of closure plate.
As shown in Figure 1 and Figure 2, circular base plate 3 is fixedly welded with at the opening end 7 that conical shell is little, the opening end diameter that circular base plate diameter is little with conical shell is identical, opening end little for conical shell is closed by base plate, namely base plate is as the plugging plate of the little opening end of conical shell, and the diameter of little opening end is unsuitable too small, and namely the diameter of base plate is unsuitable too small, prevent hydraulic pressure from concentrating at this, namely stressed concentrated.
Base plate is fixed near conical shell inner chamber side and is welded with very much floor 5, floor achieves base plate and is connected with the firm of conical shell internal chamber wall, strengthens the intensity of closure plate entirety, can bear larger pressure during the hydraulic testing.
Be fixedly welded with the short tube 2 of a circle at the opening end 8 that conical shell is large, this short tube with need pipeline opening 9 solid welding of the circulating line carrying out the hydraulic testing to be integrated.The transition body that short tube is connected with pipeline opening as this blind structure, the pipeline opening diameter of diameter and circulating line is suitable.Angle side bracket 6 is had at conical shell internal chamber wall and short tube soldered place one week uniform welding, angle side bracket achieves short tube as reinforcement and is firmly connected with the effective of cone shell, strengthen the intensity of this blind structure entirety, also enhance the hydraulic pressure that this blind structure can bear to a certain extent.
Outside short tube, be fixedly welded with the stiffening ring 4 of a ring shape, stiffening ring enhances the intensity of short tube and whole closure plate to a certain extent.
Further, the opening end diameter that described conical shell is large is 2400mm ~ 3200mm, is applicable to the hydraulic testing of bigbore circulating line.
Further, described angle side bracket is triangular plate, and the both sides of triangular plate are welded on the large opening end inwall of conical shell and circular short tube inwall respectively.
Further, the weld seam between conical shell and base plate, short tube is closed weld seam, namely ensure all weld seams can not cause during the hydraulic testing cause commissure to ftracture, damaged etc.
Above-described embodiment is only the description carried out preferred implementation of the present utility model; not scope of the present invention is limited; under the prerequisite not departing from the utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in the determined protection domain of the utility model claims.
