Abstract
The invention discloses a diesel engine post-vertex exhaust connecting pipe of a wet water jacket structure. The diesel engine post-vertex exhaust connecting pipe comprises a cooling liquid outlet, annular water cavities, supporting plates, a connecting flange, an inner wall and an outer wall, and is characterized in that the annular water cavities are arc sections surrounding the pipe annular edge and located in an interlayer between the inner wall and the outer wall, each of the two sides of the annular water cavities is located in an interlayer between two corresponding adjacent supporting plates, and the volume of each annular water cavity is equal to the sum of the flowing area of cooling liquid flowing through the annular water cavity and the thickness of the corresponding supporting plate between two corresponding annular water cavities; the corresponding supporting plate between every two adjacent water cavities of the wet water jacket structure supports the parts, on the outer walls of the water cavities, of the pipe body, and each supporting plate is provided with a plurality of through holes which are linearly arrayed along the center line of the pipe at intervals so that the cooling liquid can flow through. The diesel engine post-vertex exhaust connecting pipe is simple in structure, high in practicality, significant in effect, good in leakproofness and excellent in cooling performance.
Description
Technical field
The present invention relates to diesel engine realm, particularly on a kind of high-speed boat higher to whole ship travelling comfort requirement.
Background technique
Final vacuum connecting tube in diesel engine whirlpool is the important component part of engine intake and exhaust system.The mixture of fuel and air is when combustion chambers burn, and a large amount of heat produced is discharged mainly through waste gas.Therefore, the diesel engine whirlpool final vacuum connecting tube of wet type jacket structure for water serves very important effect for the heat extraction effect of whole ship and discharge noise.
Shown in Fig. 1 and Fig. 2, which show the high-speed diesel engine whirlpool final vacuum connecting tube plan view according to the wet type jacket structure for water of prior art and longitudinal sectional view.Current domestic and international traditional whirlpool final vacuum connecting tube only plays transition connection function, and ship diesel engine is by being generally all the motor that rotating speed is high, and thus row's temperature is higher, vibrations are larger.And the high heat diffusion area determining diesel engine whirlpool final vacuum connecting tube will be larger of row's temperature.Because current conventional dry whirlpool final vacuum connecting tube heat dissipation potential is poor, cannot take away the heat that waste gas produces in time, what the temperature in cabin therefore can be made to rise is higher, and the row's of making temperature noise also can improve, thus the travelling comfort of whole ship is reduced greatly.
Summary of the invention
The object of this invention is to provide a kind of high-speed boat diesel engine whirlpool final vacuum connecting tube for wet type jacket structure for water, it effectively can reduce cabin temperature, and reduce discharge noise value, the comfort level of rectifier ship is improved greatly, safely, fast, good airproof performance, the diesel engine whirlpool final vacuum connecting tube of a kind of wet type jacket structure for water of good fluidity.
Technical solution of the present invention is such, a kind of diesel engine whirlpool final vacuum connecting tube of wet type jacket structure for water, comprise cooling liquid outlet, annular water chamber, dunnage, adpting flange, inwall, outer wall, it is characterized in that annular water chamber (2) is by pipe ring limit shape arc section, annular water chamber (2) is positioned at inwall (5), interlayer between outer wall (6), annular water chamber (2) both sides are positioned at the interlayer between two adjacent shore plates (3), the volume of annular water chamber (2) is the thickness that cooling liquid that cooling liquid outlet (1) enters flows through the dunnage (3) between the area of annular water chamber (2) and two adjacent annular water cavities (2).
Annular water chamber (2) is the water cavity around caliber ring limit.
Dunnage (3) is in the radial direction of caliber.
Dunnage (3) has more than one.
Annular water chamber (2) has more than one.
Cooling liquid outlet (1) has bolt, gasket seal to lock.
Dunnage (3) has the through hole of the multiple gaps certain distance along the arrangement of pipeline center line.
Compared with prior art, the present invention has following beneficial effect: effectively can reduce delivery temperature and reduction diesel engine level of noise in high-speed boat diesel oil cabin, the travelling comfort of whole ship is improved greatly.Structure is simple, practical, good airproof performance, Be very effective.
