Embodiment 1

[0038] like figure 1 As shown, a surface galvanized and electrophoretic engine water pipe includes a hard pipe body. Both ends of the hard pipe body are provided with connecting joints and brackets matched with the corresponding connecting joints, and a water outlet branch pipe is connected to the middle part of the hard pipe body. The water outlet branch pipe is provided with a sealing brazing part which is sealedly connected with the outer side wall of the hard pipe body, so as to realize a stable sealing connection structure. At the same time, a galvanized layer and an electrophoretic layer are sequentially arranged on the inner and outer sides of the engine water pipe. Therefore, the connection joints at the two ends of the hard pipe body are used to connect the external pipeline, and the water outlet is carried out by the water outlet branch pipe, and the sealed brazing part realizes stable welding and fixing. The thickness of the galvanized layer is 12 μm, and the thic...

Embodiment 2

[0053] like figure 1 As shown, a surface galvanized and electrophoretic engine water pipe includes a hard pipe body. Both ends of the hard pipe body are provided with connecting joints and brackets matched with the corresponding connecting joints, and a water outlet branch pipe is connected to the middle part of the hard pipe body. The water outlet branch pipe is provided with a sealing brazing part which is sealedly connected with the outer side wall of the hard pipe body, so as to realize a stable sealing connection structure. At the same time, a galvanized layer and an electrophoretic layer are sequentially arranged on the inner and outer sides of the engine water pipe. Therefore, the connection joints at the two ends of the hard pipe body are used to connect the external pipeline, and the water outlet is carried out by the water outlet branch pipe, and the sealed brazing part realizes stable welding and fixing. The thickness of the galvanized layer is 21 μm, and the thic...

Embodiment 3

[0068] like figure 1 As shown, a surface galvanized and electrophoretic engine water pipe includes a hard pipe body. Both ends of the hard pipe body are provided with connecting joints and brackets matched with the corresponding connecting joints, and a water outlet branch pipe is connected to the middle part of the hard pipe body. The water outlet branch pipe is provided with a sealing brazing part which is sealedly connected with the outer side wall of the hard pipe body, so as to realize a stable sealing connection structure. At the same time, a galvanized layer and an electrophoretic layer are sequentially arranged on the inner and outer sides of the engine water pipe. Therefore, the connection joints at the two ends of the hard pipe body are used to connect the external pipeline, and the water outlet is carried out by the water outlet branch pipe, and the sealed brazing part realizes stable welding and fixing. The thickness of the galvanized layer is 32 μm, and the thic...

Abstract

The invention discloses a surface-galvanized and electrophoresis engine water pipe, which relates to the technical field of engine water pipes, and is characterized in that the surface-galvanized and electrophoresis engine water pipe comprises a hard pipe body, connecting joints and brackets matched with the corresponding connecting joints are arranged at the two ends of the hard pipe body, and a water outlet branch pipe is connected to the middle part of the hard pipe body; the water outlet branch pipe is provided with a sealing brazing part which is in sealing connection with the outer side wall of the hard pipe body; the inner side and the outer side of the engine water pipe are each sequentially provided with a zinc coating and an electrophoresis layer. Stable welding and fixing are achieved through the sealing brazing part; according to the engine water pipe, the inner side and the outer side of the engine water pipe are each provided with a zinc coating and an electrophoresis layer which sequentially cover the inner side and the outer side of the engine water pipe, so that the anti-corrosion performance of the engine water pipe with the zinc-plated and electrophoresis surface is remarkably improved, and the engine water pipe with the zinc-plated and electrophoresis surface is effectively prevented from rusting in the turnover transportation and long-term use process; and the purpose of corrosion resistance and no red rust within 2000h is achieved.

Description

technical field [0001] The invention relates to the technical field of engine water pipes, in particular to a surface galvanized and electrophoretic engine water pipe. Background technique [0002] External pipes and water pipes are used in the cooling system of automobile engines. Water pipes are an indispensable part of the engine cooling system. For those with short connection distance and sufficient space, the hose connection is generally used, and for those with compact space but high precision requirements, the general use of Steel pipes are connected, and more often, steel pipes are used as skeleton pipes, and rubber pipes are used as auxiliary pipes to connect steel pipes and other structures to form external pipes. [0003] The Chinese patent with the publication number CN103836277B discloses a water pipe for an automobile engine. The water pipe for the automobile engine includes a pipe body and a portable pipe joint. One end of the pipe body is a flat water pipe jo...
