Abstract
The utility model relates to a kind of point of bucket.This device comprises cylindrical shell, the end socket be connected with below cylindrical shell, and described end socket is given prominence to downwards, and is provided with weep hole in center.Described in the utility model point of bucket apparatus structure is simple, can not the realization of influential system normal safe function, when in turn ensure that power plant normally runs, inside can not be accumulated liquid and caused equipment unavailable, can improve the reliability of system and equipment, reduces power plant's operating cost.
Description
Technical field
The utility model relates to a kind of point of bucket, is specifically related to a kind of point bucket preventing liquid from accumulating.
Background technology
Point bucket applied in AP1000 nuclear power plant pcs system generally adopts structure shown in Fig. 1.Point bucket of this structure after mounting, may because of the reason of alignment error and temperature stress, cause a point bucket body run-off the straight, and then it is icing that water leakage when regularly testing or normally run can be caused further to assemble in point bucket, may block end socket central hydrophobic hole time serious, impact needs point water efficiency during system acting.The personnel of needing repairing make regular check on and get rid of and accumulate liquid.
Utility model content
For the defect existed in prior art, the purpose of this utility model is to provide a kind of point of bucket.This apparatus structure is simple, can not the realization of influential system normal safe function, and when can ensure that power plant normally runs again, inside can not be accumulated liquid and caused equipment unavailable, can also improve the reliability of system and equipment, reduce power plant's operating cost.
For reaching above object, the technical solution adopted in the utility model is: a kind of point of bucket, comprise cylindrical shell, be arranged on the end socket below cylindrical shell, described end socket is given prominence to downwards, and center is provided with weep hole.
Further, described end socket is taper, ellipse or butterfly, is bent shaping by stainless steel, and is welded on the below of cylindrical shell.
Further, described end socket central hydrophobic bore dia is less than or equal to 12.7mm.
Further, the overall height of installing point bucket of end socket divides bucket height consistent with flat head.
Further again, be assigned 16 road bypass channels at described drum surface.
Further, the upper end of said cylindrical shell is provided with three pieces of suspension brackets, and three pieces of suspension and supports are apart from one another by 120 °.
Effect of the present utility model is: adopt device described in the utility model, structure is simple, can not the realization of influential system normal safe function, when can also ensure that power plant normally runs, inside can not be accumulated liquid and caused equipment unavailable, the reliability of system and equipment can be improved, reduce power plant's operating cost.

Fig. 2 (a), Fig. 2 (b) are respectively vertical view and the front view of a kind of point of bucket structure in the utility model embodiment;
Fig. 3 (a), Fig. 3 (b) are respectively vertical view and the front view of point bucket structure in another embodiment of the utility model;
Wherein, cylindrical shell 1, conical head 2, weep hole 3, suspension bracket 4, bypass channel 5.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 2, a kind of point of bucket structure, comprises cylindrical shell 1, is arranged on the conical head 2 below cylindrical shell 1, weep hole 3, the three pieces of suspension brackets 4 processed at the center of conical head 2 and the 16 road bypass channels 5 processed on cylindrical shell.
In the present embodiment, described conical head 2 conical head is bent shaping by stainless steel, and is welded on below cylindrical shell 1, and three pieces of suspension brackets 4 are welded in above cylindrical shell 1 apart from one another by 120 °, common composition one point of bucket.When chilled water divides bucket from the inflow of top pipeline, the pipeline of chilled water above point bucket flows into, and through 16 road bypass channel mean allocation to containment top, reaches the object of cooling containment.Another part converges bottom bulkhead part, and due to the special tectonic of taper, the water of convergence flows to the minimum point of conical head, i.e. taper center separately.
In the present embodiment, the diameter of described weep hole 3 is no more than 12.7mm, and conical head divides the overall height of bucket the height of bucket should be divided to be consistent with flat head, so just can ensure the consistance that point bucket of two kinds of forms distributes current.The current flowing into conical head 2 are discharged by weep hole, avoid owing to adopting flat head structure to freeze because run-off the straight causes water leakage when regularly experiment or normal operation to be assembled in point bucket, the phenomenons such as end socket central hydrophobic hole may be blocked time serious and occur.
Adopt point bucket described in the present embodiment, pcs system can be worked as when regularly testing, or power plant is when normally running, water leakage flows into a point bucket, the angle of conical head can ensure that point bucket is under the alignment error allowed and thermal stress, water leakage can both be flowed out by weep hole, avoids the edge that liquid accumulates in point bucket, prevents liquid from accumulating.Thus improve the reliability of system and equipment, reduce power plant's operating cost.
As shown in Figure 3, in another embodiment of the present utility model, described end socket 2 can also be ellipsoidal head, butterfly end socket or other nonplanar end socket outstanding downwards.
In addition, the quantity of bypass channel is also not limited to 16 roads, can arrange flexibly according to the actual needs.
Device described in the utility model is not limited to the embodiment described in embodiment, and those skilled in the art draw other embodiment according to the technical solution of the utility model, belongs to technological innovation scope of the present utility model equally.
