Description

Technical Field

[0001] The utility model relates to the technical field of EGR valves, in particular to an easily disassembled and assembled plug-in EGR valve. Background Art

[0002] The EGR valve, full name of the exhaust gas recirculation valve, is a mechatronic product installed on a diesel engine to control the amount of exhaust gas recirculation fed back to the intake system. Its main function is to control the amount of exhaust gas entering the intake manifold, so that a certain amount of exhaust gas flows into the intake manifold for recirculation.

[0003] The EGR valve of the prior art needs to remove multiple bolts when it needs to be repaired and disassembled, which is inconvenient and leads to relatively low work efficiency during repair. Utility Model Content

[0012] The utility model has the following beneficial effects:

[0013] (1) The utility model aligns the three protrusions with the three slide grooves, and then inserts the connecting pipe into the interior of the sleeve. While inserting, the protrusions will squeeze the inside of the spring locking installation groove, and then the protrusions will slide inside the slide groove. When sliding to the connection point between the adapter groove and the slide groove, the connecting pipe is rotated to make the protrusion slide inside the adapter groove. When the arc surface clamping block coincides with the clamping hole, the arc surface clamping block will be clamped into the inside of the clamping hole, and the installation can be completed. By rotating the EGR valve body, the arc surface clamping block presses against the edge of the clamping hole and shrinks the arc surface clamping block into the interior of the installation groove, and the contact and clamping can be achieved. The protrusions can be slid out along the adapter groove and the slide groove to complete the separation between the EGR valve body and the connecting plate. Then the EGR valve body can be repaired. The disassembly is convenient and quick, avoiding the situation where multiple bolts need to be removed to disassemble and repair the EGR valve body, thereby improving work efficiency.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
