Technical Field

The invention relates to a part for cooling an automobile, in particular to a water outlet adapter of an integrated EGR valve.

Background

At present, an EGR valve for an existing gasoline engine is generally directly mounted on a cylinder cover, the EGR valve is more and more compact in arrangement along with the fact that the volume of a small-displacement engine is smaller and smaller, subsequent mounting cannot be guaranteed in a mounting mode of directly mounting the EGR valve on the cylinder cover, and the EGR valve is inconvenient to maintain.

Disclosure of Invention

In order to solve the problems in the background art, the invention provides an outlet adapter of an integrated EGR valve.

The invention adopts the following technical scheme: a water outlet adapter of an integrated EGR valve comprises a water outlet adapter body and an EGR air passage; the water outlet adapter is characterized in that the water outlet adapter body is of a cylindrical structure, the cylinder is vertically arranged, a water outlet pipe flange is fixed at the top end of the cylinder, a water through hole is formed in the side wall of the cylinder, a water temperature sensor flange is arranged on the outer side of the water through hole, a threaded mounting hole is formed in the water temperature sensor flange, a cylinder cover flange is arranged at the bottom end of the cylinder, and a plurality of mounting light holes I are formed in the side wall of the cylinder cover flange along the circumferential direction of the; the EGR air passage and the water outlet adapter body are integrally formed, an air inlet manifold flange is arranged at one end, away from the water temperature sensor flange, of the EGR air passage, and a threaded hole I is formed in each of two sides of the air inlet manifold flange; the bottom of EGR air flue closes on air intake manifold flange department and is equipped with air flue entry flange, the both sides of air flue entry flange are equipped with a mounting light hole two respectively, and the top of EGR air flue is equipped with EGR air inlet flange, the middle part of EGR air inlet flange is equipped with two EGR air inlets, and the both sides of EGR air inlet flange are equipped with a screw hole two respectively, air flue entry flange, EGR air inlet flange and air intake manifold flange set gradually according to the gas flow direction.

Compared with the prior art, the invention has the beneficial effects that:

when the EGR valve is installed, the water outlet switching structure of the integrated EGR channel is used for transitional connection, so that the water pipe switching and the EGR valve assembling operability can be met, the overall size of the external profile of the engine is not increased, the structure is simple, and the use and the maintenance are convenient.
