Technical Field

The invention belongs to the technical field of ship seawater systems, particularly belongs to a device for preventing pipelines from being corroded on ship seawater pipelines, and relates to a seawater pipeline sacrificial elbow.

Background

The marine seawater system plays an important role in ensuring the normal operation and safety of main equipment of the ship, and the pipes used by the marine seawater system are mostly metal pipes. The medium that sea water system carried is sea water, and sea water is the medium of strong corrosivity, causes sea water system to face serious corrosion problem, once break down, will seriously influence the normal operation of equipment and the safe navigation of boats and ships.

Electrochemical corrosion is the most common corrosion type of seawater pipeline, and in a seawater medium, dissimilar metals are in contact with a potential difference in seawater to form a galvanic couple (cathode and anode) to cause electrochemical corrosion.

According to the principle of electrochemical corrosion, a metal which is more active than the metal is usually connected to the protected metal, the active metal is corroded as an electrochemical anode, and the protected metal is protected as a cathode. According to the principle, the corrosion-resistant zinc block is additionally arranged in the current general means, the corrosion-resistant effect is good, the service life can reach about 3 years, but the field replacement is difficult during repair, for example, the corrosion-resistant zinc block of a seawater pipeline is additionally arranged in a sea valve box, and the disassembly and the assembly are difficult.

Disclosure of Invention

The invention aims to provide a sacrificial elbow for a seawater pipeline, which is characterized by comprising: the seawater pipeline sacrificial elbow is arranged in the seawater pipeline, and the two ends of the seawater pipeline sacrificial elbow are connected with the part hinged with the seawater pipeline through flanges.

Preferably, the sacrificial elbow material of the seawater pipeline is pig iron.

Preferably, the flange is a loose flange.

The invention discloses a sacrificial elbow of a seawater pipeline, which is made of pig iron, replaces the elbow in the original pipeline in the existing seawater main pipe, adopts a copper pipe as the seawater pipeline, is more active than copper, can be used as a sacrificial anode in the pipeline, thereby playing a role in protecting the seawater pipeline, and is easy to replace by adopting loose flange connection. The general replacement cycle is a month, the adjustment of the replacement cycle can be carried out according to the difference of sea areas, if the elbow has seawater leakage, the valves on the two sides of the elbow can be closed, and the elbow can be replaced by detaching the flange of the elbow, so that the operation is simple, and the guarantee is convenient and effective.

Drawings

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

FIG. 1 is a schematic diagram of the present invention patent;

fig. 2 is a cross-sectional view of the present invention patent.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below. Aiming at the arrangement of the existing seawater main pipe, the seawater pipeline is mainly provided with an anticorrosive zinc block, and the protection means of the internal seawater pipeline is lost.

The invention discloses a sacrificial elbow for a seawater pipeline, which is mainly characterized in that an elbow corresponding to the pipeline is made of pig iron, a loose flange is adopted to be matched with an original pipeline through the loose flange, the sacrificial elbow is convenient to assemble and disassemble, and the sacrificial elbow is convenient to replace regularly by recording the service cycle.

The invention discloses a sacrificial elbow for a seawater pipeline, which replaces an elbow existing in an original pipeline in the existing seawater main pipe, and the seawater pipeline is usually made of a copper pipe, is more active than copper and an elbow made of pig iron material, can be used as a sacrificial anode in the pipeline, thereby playing a role in protecting the seawater pipeline, and is easy to replace by adopting loose flange connection.

As shown in fig. 1 and 2, the sacrificial elbow of the seawater pipeline aims at preventing corrosion of the seawater pipeline in the cabin. The invention can greatly reduce the workload of daily maintenance of the seawater pipeline by configuring the sacrificial elbow under the condition of not influencing the daily use of the seawater pipeline, and is beneficial to a sailor to master the corrosion rule of the seawater pipeline by a daily combing corrosion period.

The invention discloses a sacrificial elbow of a seawater pipeline, which is made of pig iron, replaces the elbow in the original pipeline in the existing seawater main pipe, adopts a copper pipe as the seawater pipeline, is more active than copper, can be used as a sacrificial anode in the pipeline, thereby playing a role in protecting the seawater pipeline, and is easy to replace by adopting loose flange connection. The general replacement cycle is a month, the adjustment of the replacement cycle can be carried out according to the difference of sea areas, if the elbow has seawater leakage, the valves on the two sides of the elbow can be closed, and the elbow can be replaced by detaching the flange of the elbow, so that the operation is simple, and the guarantee is convenient and effective.

It will be apparent to those skilled in the art that various changes and modifications may be made in the invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
