Abstract

A kind of connection structure of cylinder of diesel engine jacket water exit branch, it is installed between the jacket-cooling water exit branch of diesel engine and cooling supply mains, it is characterized by: the connection structure is flexible metal hose, one end of the metal hose is connect with the jacket-cooling water exit branch, the other end is connect with the cooling supply mains, realizes the flexible connection between the cylinder of diesel engine jacket water exit branch and cooling supply mains in all directions.The utility model uses connection by metal hose, realize the flexible connection between cylinder of diesel engine jacket water exit branch and cooling supply mains in all directions, it avoids rigid connection and damages the generation for leading to water leakage situation because of operational shock, have many advantages, such as that simple and compact for structure, strong applicability, easy to adjust, dismounting is convenient, safe and reliable, can be widely applied to marine low speed diesel engine.

Description

A kind of connection structure of cylinder of diesel engine jacket water exit branch
Technical field
The utility model relates to a kind of diesel engine cooling system structures, and in particular to a kind of cylinder of diesel engine jacket water water outlet The connection structure of branch pipe, belongs to Diesel Engine Technique Field.
Background technique
Connection uses expansion pipe between existing cylinder of diesel engine jacket water exit branch and cooling supply mains, such as Shown in Fig. 1, connection rigidity is very big, and being easy to damage when diesel engine works because of vibration leads to leak, to influence diesel engine It works normally, or even causes safety accident, thus to design a kind of connecting tube flexible.
Utility model content
Technical problem to be solved in the utility model is that the connection type that overcomes existing cooling water exit branch traditional is rigid Property it is big, be easy to damage when diesel engine is run because of vibration to lead to the deficiency of leak, a kind of cylinder of diesel engine jacket water be provided and The connection structure of water branch pipe substitutes original expansion pipe using the new connection structure of metal hose, to avoid cylinder sleeve cooling Water exit branch is damaged because of vibration, is improved production security, is reached safe and reliable, economic beneficial effect.
Based on above-mentioned purpose, the technical scheme that the utility model is provided is as follows:
A kind of connection structure of cylinder of diesel engine jacket water exit branch is installed on the jacket-cooling water water outlet branch of diesel engine Between pipe and cooling supply mains, it is characterised in that: the connection structure is flexible metal hose, the one of the metal hose End is connect with the jacket-cooling water exit branch, and the other end is connect with the cooling supply mains, realizes that the diesel cylinder sleeve is cold But the flexible connection between water exit branch and cooling supply mains in all directions.
As a further improvement, the metal hose includes the flange and intermediate hose main body at both ends, two flange It is connected to the both ends of the hose main body.
As a further improvement, the flange is lap joint flange.
As a further improvement, the surface of the hose main body is equipped with the wire mesh for protection.
As a further improvement, the metal hose by bolt, nut and metal gasket respectively with the diesel engine Jacket-cooling water exit branch is connected with cooling supply mains.
As a further improvement, the metal gasket is made of Q235A steel, outer surface is coated with fluororubber layer.
As a further improvement, the operating temperature of the metal hose is 600 DEG C.
Compared with traditional expansion pipe connection, the utility model is had the advantage that
1, the connection structure uses connection by metal hose, realizes cylinder of diesel engine jacket water exit branch and cooling water Flexible connection between general pipeline in all directions, avoiding rigid connection and damaging because of operational shock leads to water leakage situation Occur, thus has the advantages that safety is good.
2, metal hose is flexible, strong applicability, easy to adjust.
3, the utility model is simple and compact for structure, and materials procurement is convenient.
4, installation and removal are convenient.
Detailed description of the invention
Fig. 1 is traditional expansion pipe.
Fig. 2 is the scheme of installation of the utility model.
Fig. 3 is the structural schematic diagram of the utility model.
Fig. 4 is the structural schematic diagram of metal gasket.
Fig. 5 is the portion the C enlarged drawing of Fig. 4.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments, but following embodiments is not used Limit the scope of the utility model, the equivalence changes and modification that all contents according to this specification are made belong to this The claimed technical scope of utility model application.
Referring to Fig. 2, the connection structure of the cylinder of diesel engine jacket water exit branch is flexible metal hose 03, For substituting the biggish expansion pipe of original rigidity.One end of the metal hose 03 and the jacket-cooling water exit branch 01 connection, the other end are connect with the cooling supply mains 02, realize the cylinder of diesel engine jacket water exit branch 01 and cooling water Flexible connection between general pipeline 02 in all directions.
Referring to Fig. 3, diagram metal hose includes the flange 1 and intermediate hose main body 2 at both ends, two flange 1 difference It is connected to the both ends of the hose main body 2.
The flange 1 is lap joint flange.
The surface of the hose main body 2 is equipped with the wire mesh 3 for protection.
Flange 1, hose main body 2 and the wire mesh 3 is connected as one, and can directly be ordered on the market.
Referring to Fig. 2, the metal hose 03 is gone out with the jacket-cooling water respectively by bolt, nut and metal gasket Water branch pipe 01 and cooling supply mains 02 connect.The 03 design work temperature of metal hose is 600 DEG C, there is bending radius standard.
For the sealing for guaranteeing the metal hose 03 with jacket-cooling water outlet pipeline 01 and cooling 02 junction of supply mains Property do not influenced by factors such as high temperature, the metal gasket use special gasket, please refer to Fig. 4 and Fig. 5, the metal gasket use Q235A steel are made, and outer surface is coated with fluororubber layer 4.
The metal hose 03 realizes flexible connection, thus thoroughly solves traditional jacket-cooling water exit branch and be easy The problem of because of the damage of external force reason;Simultaneously because metal hose 03 allows to be bent, therefore strengthen jacket-cooling water outlet pipeline Design flexibility.
The utility model has many advantages, such as that simple and compact for structure, versatility is good, dismounting is convenient, buying is convenient, safe and reliable, It can be widely applied to marine low speed diesel engine.
Protection scope required by the utility model is not limited only to above-described embodiment, also should include other to the utility model Obvious transformation and alternative solution.
