Abstract
The invention discloses a chemical adding pipeline for a ship ballast water management system and a connection method of a ballast water main pipeline. Firstly, a connection hole is arranged on the ballast water main pipeline, a steel flange is welded on the connection hole, the inner end of an L-shaped chemical adding inner connection pipe is inserted in the steel flange in matched mode, the outer end of the chemical adding inner connection pipe and the butt joint end of a chemical adding outer connection pipe are provided with a pair of flanges corresponding to the steel flange, and the three flanges are sealed through rubber cushion rings and mutually fastened through bolts and nuts. The chemical adding pipeline has the advantages of being capable of achieving effective connection between the chemical adding pipeline made of special materials and the ballast water main pipeline made of low carbon steel materials, enabling materials of the chemical adding pipeline to be not limited, preventing internal lining rubber of steel pipelines from being damaged, being simple in construction and easy to operate, and meeting requirements of the chemical adding pipeline for corrosion resistance.
Description
Technical field
The present invention relates to the connecting means between a kind of ballast for cruising water management system dosing pipe and the ballast water main line, be mainly used in the Ballast water treatment system, belong to ship domain.
Background technique
For the ballast for cruising water management system that uses active substance, because active substance generally has strong oxidizing property and corrosivity, its dosing pipe must be selected the steel pipe of corrosion resistant material or inner line with rubber.In the existing dosing pipe interconnection technique, the effective connection between foreign material and the ballast water main line (low-carbon steel material) can't be realized, the steel pipe of inner line with rubber can only be used.
For the steel pipe of inner line with rubber and being connected of ballast water main line; The technology that adopts at present is: cut off a tubing from the ballast water main line earlier; This tubing and dosing steel pipe are welded together, then weld assembly is transported to the line with rubber workshop together, the dosing pipe inwall is carried out the line with rubber construction.After the line with rubber construction finishes, transport back on the ship again, the tubing that originally cut off is welded to the origin-location, with this weld assembly is fixed on the ballast water main line, the realization dosing pipe is communicated with the ballast water main line.
The deficiency of above-mentioned existing technology is: the one, can't realize being connected between foreign material and the ballast water main line (low-carbon steel material); Can only use the steel pipe of inner line with rubber; Selection range is restricted, and some noncorrosive materials such as UPVC, titanium alloy etc materials can't be used; The 2nd, when the steel pipe of inner line with rubber was connected with the ballast water main line, construction was complicated, need transport to the workshop construction by the weld assembly that volume is bigger; Carrying is difficulty very; And when carrying out weld job, still might destroy the inner line with rubber of dosing pipe, cause etching problem to take place.
Summary of the invention
The present invention is in order to solve the problem that above-mentioned existing technology exists; Connecting means between a kind of dosing pipe and the ballast water main line is provided; Both can realize being connected between xenogenesis piping material and the ballast water main line, can be used for the steel pipe of inner line with rubber and being connected of ballast water main line again.
Technological scheme of the present invention is: the connecting means of a kind of ballast for cruising water management system dosing pipe and ballast water main line; At first on the ballast water main line, open an attachment hole; In steel flanges of this attachment hole welding; In this steel flanges, insert the inner of the dosing inner connecting tube of one " L " shape; Be provided with the corresponding flange of a pair of and described steel flanges in the outer end of this dosing inner connecting tube and the butt end of dosing externally connected pipe, between three flanges, use rubber ring seal, and fastening each other with screw bolt and nut.
Described dosing inner connecting tube and dosing externally connected pipe adopt and the identical or different material of ballast water main line, or adopt the steel pipe of inner line with rubber.
Advantage of the present invention is: both can realize that the dosing pipe of foreign material is connected with the effective of ballast water main line of low-carbon steel material; Also can realize the steel dosing pipe of inner line with rubber and being connected of ballast water main line; Make that the selection of dosing pipe is no longer limited, the inside line with rubber of steel pipeline can not be damaged yet.Construction is simple, and the corrosion proof requirement of dosing pipe is satisfied in operation easily.

Embodiment
Referring to Fig. 1, several specific embodiments of the present invention are following.
Embodiment 1: dosing pipe is made up of through a pair of flange 4 butt joints dosing inner connecting tube 3 and dosing externally connected pipe 8, uses the UPVC pipe of DN40, is used for branch road electrolytic ballast for cruising water management system, and being installed in the ballast water rated flow is 300m
3On the Container ship of/h.The hole (interface) that at first on ballast water main line 1, to open a diameter be 80mm, in steel flanges 2 of this joint weld, the internal diameter of this steel flanges 2 is enough to make that the dosing inner connecting tube 3 of " L " shape inserts wherein.The bolt hole of this flange 4 just with originally be welded on the ballast water main line on steel flanges 2 corresponding.All seal between three flanges, and interfix, tighten with bolt 6 and nut 7 with rubber washer 5.Be communicated with effectively, easy construction reaches predetermined dosing effect and water quality treatment index.
Embodiment 2: the steel pipeline of dosing inner connecting tube 3 and the inside line with rubber of dosing externally connected pipe 8 use DN65, be used for branch road electrolytic ballast for cruising water management system, and being installed in the ballast water rated flow is 3000m
3On the oil carrier of/h.Connection construction method is identical with embodiment 1.
Embodiment 3: the titanium alloy pipeline of dosing inner connecting tube 3 and dosing externally connected pipe 8 use DN50, be used for branch road electrolytic ballast for cruising water management system, and being installed in the ballast water rated flow is 1500m
3On the Bulk carrier of/h.Connection construction method is identical with embodiment 1.
The dosing inner connecting tube 3 of " L " of the present invention shape with the influence of the current in the reduction ballast water main line 1 to the soup of outflow dosing inner connecting tube 3 outlets, makes soup be blended in the current equably towards the direction of current.
