Abstract
The utility model relates to a diesel engine water jacket exhaust pipe, which comprises a left exhaust pipe body and a right exhaust pipe body, wherein an inner cavity of the left exhaust pipe body is a left air passage; an inner cavity of the right exhaust pipe body is a right air passage; the outer part of the left exhaust pipe body and the right exhaust pipe is provided with a water jacket wall; gaps between the water jacket and the left exhaust pipe body and between the water jacket and the right exhaust pipe body are cooling water chambers. The diesel engine water jacket exhaust pipe adopted has the advantages that the surface temperature of the water jacket wall is not higher than 60 DEG; thus, working personnel can not be scalded, peripheral devices can not be damaged, and the utility model has favorable effects on heat insulation and protection; the existing cooling water of the diesel engine is utilized to carry out cooling to the exhaust pipe, and existing resources are fully utilized.
Description
Technical field
The utility model relates to a kind of Diesel Engine Exhaust Pipe, a kind of diesel engine water jacket outlet pipe of more specifically saying so.
Background technique
Diesel engine can produce a large amount of heats when work, make the temperature of body very high, these heats are mainly outwards distributed by outlet pipe, thereby the surface temperature that makes outlet pipe is very high, usually about 600 ℃, at improper ventilation and have under the environment that personnel work, as watercraft engine room, the ambient temperature of work-yard can be very high, both be unfavorable for the healthy of staff, had potential safety hazard again.In order to reduce the temperature of Diesel Engine Exhaust Pipe, avoid scalding the staff and damage peripheral unit, method in common is protective housing to be installed on Diesel Engine Exhaust Pipe or to be installed additional thermal-protective coating, protective housing can not play heat-blocking action, install thermal-protective coating additional owing to reasons such as heat-shielding performance and mechanical propertys, its effect and reliability are all relatively poor, can not satisfy the needs of actual use.
Summary of the invention
The purpose of this utility model provides a kind of heat dispersion and all good diesel engine water jacket outlet pipe of protection effect.
In order to realize above-mentioned purpose, the diesel engine water jacket outlet pipe that is provided, comprise left bank tracheae body and right exhaust pipe, the inner chamber of left bank tracheae body is left air flue, the inner chamber of right exhaust pipe is right air flue, its structural feature is to be provided with water jacket wall at left bank tracheae body and right exhaust pipe outside, and the gap between water jacket wall and left bank tracheae body and the right exhaust pipe is a cooling water chamber.
The above-mentioned left bank tracheae body and the outlet end of right exhaust pipe are connected to the pressurized machine connecting plate.
For the ease of installing, a side of hydroecium wall has a mounting plate, and the right-hand member position that is connected with water-in flange, right exhaust pipe at the left end position of left bank tracheae body is connected with water-output flange.
Diesel engine water jacket outlet pipe provided by the utility model is fixed on cylinder of diesel engine by clamping bolt and covers, and left bank tracheae body and right exhaust pipe are communicated with in the pipeline of diesel coolant by water-in flange and water-output flange.When diesel engine was worked, cooling water just entered cooling water chamber, flows out from water-output flange by water-in flange, and left bank tracheae body and right exhaust pipe are cooled off, and makes the surface temperature of water jacket wall not be higher than 60 ℃.
Learn by above narration, diesel engine water jacket outlet pipe provided by the utility model, owing to have additional cooling water chamber, its beneficial effect is: 1, the surface temperature of water jacket wall is not higher than 60 ℃, neither can scald the staff, do not damage peripheral unit again, played good heat insulation and protection effect; 2, utilize the existing cooling water of diesel engine that outlet pipe is cooled off, made full use of existing resource; 3, be higher than working life with the heat insulation outlet pipe of thermal-protective material, reduced the maintenance cost of diesel engine.
