Water jacket vent pipe

Abstract

The invention discloses a water jacket vent pipe. The water jacket vent pipe disclosed by the invention comprises a cooling water cavity, an air cavity and a vent port, wherein the air cavity comprises a front air channel cavity and a rear air channel cavity; the outlet ends of the front air channel cavity and the rear air channel cavity are connected with booster connecting flanges; a water jacket outer wall is formed outside the water jacket vent pipe; an empty cavity among the front air channel cavity, the rear air channel cavity and the water jacket outer wall is the cooling water cavity; an air inlet is formed on the lower surface at the rear end, and a water outlet is formed on the left side at the front end; the vent port is formed at the highest position on the upper surface of the water jacket vent pipe; the vent port is communicated with the cooling water cavity; the vertical distance of the highest position is larger than the vertical distances in other positions of the water jacket vent pipe; and one end of the water jacket vent pipe is sheathed into the vent port, and the other end is inserted into a deflation pipe in an expansion water tank. After the technical scheme is applied, the water jacket vent pipe disclosed by the invention integrates a deflation function; a deflation device which is additionally arranged on a main water outlet pipe is omitted; the structure and arrangement of a diesel engine are simplified; and the workload for installing the deflation device is reduced.

Description

technical field [0001] The invention relates to the technical field of gas discharge devices, in particular to a water jacket exhaust pipe. Background technique [0002] Water jacket exhaust pipe is an important part of high-power marine engine. The water jacket exhaust pipe includes: a cooling water chamber and an air chamber, wherein: the air chamber includes a front air passage chamber and a rear air passage chamber, the front air passage chamber communicates with the exhaust ends of the first, second and third cylinders of the diesel engine, and the rear air passage The cavity communicates with the exhaust ends of the four, five and six cylinders. The outlets of the front airway cavity and the rear airway cavity are connected with supercharger connecting flanges to connect the water jacket exhaust pipe with the supercharger. The water jacket exhaust pipe is connected with the cylinder head of the diesel engine. The outside of the water jacket exhaust pipe is the outer...

AI Technical Summary

Problems solved by technology

Therefore, to discharge the gas in the cooling water chamber, it is necessary to add a set of air release device on the main outlet pipe of the diesel engine, which makes the structure of the diesel engine complicated.

Further, when the operator installs the diesel engine, it is also necessary to install an air release device on the main outlet pipe, which increases the workload of the operator

At the same time, due to the small space of the diesel engine, the additional air release device occupies part of the space, which brings difficulties to the arrangement of other parts of the diesel engine
