Description

Technical Field

[0001] This utility model relates to the field of exhaust gas recirculation valve technology, specifically to an EGR valve that is easy to install. Background Technology

[0002] EGR valves are common automotive components; they are electromechanical products used to control the amount of exhaust gas recirculated back into the intake system. They are typically located on the right side of the intake manifold, near the throttle body, and connected to a short metal pipe leading to the exhaust manifold. Their function is to control the amount of exhaust gas entering the intake manifold, allowing a certain amount to flow into the intake manifold for recirculation. The EGR valve is a very important and critical component of the exhaust gas recirculation system.

[0003] However, existing EGR valves are usually fixed with bolts during installation. Bolt installation requires rotating the bolts multiple times, making the installation and disassembly of the EGR valve quite cumbersome. Utility Model Content

[0004] Therefore, this utility model provides an EGR valve that is easy to install, in order to solve the problem that the installation and disassembly of EGR valves in the prior art are cumbersome.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An easy-to-install EGR valve, including an EGR valve body.

[0007] The lower end of the EGR valve body is equipped with a mounting base that facilitates limiting the position of the EGR valve body.

[0008] The mounting base includes a rotating block for locking the EGR valve body.

[0009] The lower end of the EGR valve body is equipped with a fixed seat for limiting the rotating block. Both ends of the fixed seat are equipped with control components for controlling the rotating block to flip. Both ends of the fixed seat are equipped with limiting components for limiting the control components.

[0010] Furthermore, the control component includes a pull block for pulling the rotating block, and magnetic blocks for controlling the rotating block to reset are installed at both ends of the pull block.

[0011] Furthermore, a pull rod is movably installed in the middle of the pull block, and a limiting plate is installed at one end of the pull rod to facilitate pulling the pull rod.

[0012] Furthermore, a limiting block is installed in the middle of the rod body to limit the pull block in conjunction with the limiting component, and a spring is sleeved on the end of the pull rod near the limiting plate.

[0013] Furthermore, the fixed base has slots at both ends to facilitate the insertion of the rotating block, and slots are provided on one side of the cavity of slot one.

[0014] Furthermore, the limiting component has a groove for sliding the pull block at one end near the slot one, and a limiting hole is formed in the middle of the limiting component. The limiting hole has a slot three for the limiting block to pass through.

[0015] Furthermore, the mounting base includes a plug, a limiting groove is machined in the middle of the plug, a limiting shaft for limiting the rotating block is installed on one side of the limiting groove, and a magnetic block is installed at the upper end of the plug.

[0016] Furthermore, a reinforcing rib is installed on one side of the rotating block to increase its mechanical strength, and a magnetic block three is installed in the middle of the rotating block to limit the rotation of the rotating block in conjunction with magnetic block two, and magnetic block one cooperates with magnetic block three to control the rotation of the rotating block.

[0017] This utility model has the following advantages:

[0018] When installing the EGR valve body on the mounting base, the fixing base should be placed at the top of the mounting base, and the insert block should pass through the slot of slot one, while the reinforcing rib should pass through the slot of slot two simultaneously. Then, the limiting plate should be rotated so that the limiting block slides from the slot of the slide groove to the slot of slot three. Under the push of the spring, the pulling block moves and pulls the rotating block, causing the rotating block to rotate around the limiting shaft. The rotating block and slot one are misaligned, thereby completing the rapid locking of the EGR valve body. Attached Figure Description

[0033] Please see Figures 1-6 This utility model provides an EGR valve that is easy to install, including an EGR valve body 100.

[0034] The lower end of the EGR valve body 100 is equipped with a mounting base 200 for limiting the position of the EGR valve body 100. The mounting base 200 includes a rotating block 220 for locking the EGR valve body 100.

[0035] A fixed base 110 for limiting the rotation block 220 is fixedly installed at the lower end of the EGR valve body 100. A control component 120 for controlling the rotation block 220 to flip is installed at both ends of the fixed base 110. The control component 120 includes a pull block 121 for pulling the rotation block 220. A magnetic block 122 for controlling the rotation block 220 to reset is fixedly installed inside both ends of the pull block 121. When the rotation block 220 moves, the pull block 121 moves synchronously under the action of the magnetic block 122.

[0036] A pull rod 123 is movably mounted on the middle of the pull block 121. A limiting plate 126 is fixedly mounted on one end of the pull rod 123 to facilitate pulling the pull rod 123. A limiting block 124 is fixedly mounted on the middle of the pull rod 123 to cooperate with the limiting component 130 to limit the pull block 121. A spring 125 is sleeved on the end of the pull rod 123 near the limiting plate 126 to control the pull block 121 to drive the rotating block 220 to flip, so that the mounting base 200 can be quickly locked.

[0037] The fixed base 110 has slots 111 at both ends to facilitate the insertion of the rotating block 220. Slot 111 is a V-shaped cavity, and slot 212 is provided on one side of the cavity of slot 111.

[0038] The fixed base 110 has limiting components 130 fixedly installed at both ends to limit the operation component 120. The end of the limiting component 130 near the slot 111 has a groove 131 for the pull block 121 to slide. By limiting the pull block 121 through the groove 131, the pull block 121 cannot rotate when the pull rod 123 rotates. The limiting component 130 has a limiting hole 132 in the middle, and the pull rod 123 is located in the cavity of the limiting hole 132. The cavity of the limiting hole 132 is machined with a slot 133 for the limiting block 124 to pass through. When the limiting block 124 moves through the slot 133 to the cavity of the slide groove 131, the pull rod 123 is rotated, and the rotation angle is not equal to 180 degrees, so that the position of the pull block 121 can be fixed. Before the EGR valve body 100 and the mounting base 200 are assembled, the rotating block 220 can be inserted into the cavity of the slot 111.

[0039] Mounting base 200 includes insert blocks 210, and fixed insert blocks 210 are mounted at both ends of mounting base 200. A limiting groove 211 is machined in the middle of insert block 210, and rotating block 220 is located in the groove cavity of limiting groove 211. A limiting shaft 212 for limiting rotating block 220 is installed on one side of the groove cavity of limiting groove 211, and a magnetic block 213 is fixedly installed on the upper end of insert block 210.

[0040] A reinforcing rib 221 for increasing the mechanical strength of the rotating block 220 is fixedly installed on one side, and the reinforcing rib 221 can pass through the cavity of the slot 212. A magnetic block 3 222 for limiting the rotating block 220 in conjunction with magnetic block 213 is fixedly installed in the middle of the rotating block 220. When magnetic block 213 and magnetic block 3 222 attract each other, the rotating block 220 is stably placed in the cavity of the limiting groove 211. Magnetic block 122 and magnetic block 3 222 control the rotation of the rotating block 220. When magnetic block 122 and magnetic block 3 222 attract each other, the rotating block 220 can be driven to reset.

[0041] When installing the EGR valve body 100 on the mounting base 200, the fixing base 110 is placed on the upper end of the mounting base 200, and the insert 210 passes through the slot of slot one 111, and the reinforcing rib 221 passes through the slot of slot two 112 at the same time. Then the limiting plate 126 is rotated, so that the limiting block 124 slides from the slot of the slide groove 131 to the slot of slot three 133. Under the push of the spring 125, the pull block 121 is moved. The pull block 121 pulls the rotating block 220, so that the rotating block 220 rotates around the limiting shaft 212 as the pivot. The rotating block 220 and slot one 111 are misaligned, thereby completing the quick locking of the EGR valve body 100.

[0042] When disassembling the EGR valve body 100, press the limiting plate 126 towards the limiting assembly 130 to make the limiting block 124 slide from the slot of slot 3 133 to the slot of slide groove 131, and rotate the pull rod 123 to make the limiting block 124 move away from the slot of slot 3 133. When the pull rod 123 drives the pull block 121 to move, the magnetic block 122 cooperates with the magnetic block 3 222 to drive the rotating block 220 to reset, so that the EGR valve body 100 can be disassembled.

[0043] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
