Technical Field

[0001] This utility model relates to the technical field of diesel engine parts, and in particular to a diesel engine water circuit connector. Background Technology

[0002] During the operation of a diesel engine, the stable connection of the water system is crucial. The diesel engine water connector, as a key component connecting various parts of the water system, directly affects the cooling effect and overall performance of the diesel engine. In practical applications, diesel engine water connectors typically require the following technologies:

[0003] 1. Connection structure design, such as using threaded connection, compression fitting connection, etc., to ensure that the joint is tightly connected to the water pipe or other components to prevent water leakage;

[0004] 2. Sealing technology, such as the use of rubber sealing rings and gaskets, enhances the sealing performance of the joints and ensures the normal operation of the water system;

[0005] 3. Material selection: Choose suitable metal materials (such as copper alloys, aluminum alloys, etc.) or engineering plastics to ensure they have good corrosion resistance, pressure resistance and a certain degree of flexibility to adapt to different working environments.

[0006] In a water-cooled diesel engine, the heat dissipation of the coolant circulation system directly affects the various performance characteristics of the diesel engine, and may even affect the normal operation of the diesel engine and the entire vehicle. Therefore, the structure of the cooling circulation pipeline is particularly important.

[0007] However, during the implementation of the above technical solutions, at least the following technical problems were found: Most of the water circuit joints of the current diesel engine water-cooled diesel engine are integrated with the water pipe. If the joint or water pipe fails, a whole cooling water pipe of the same size and shape needs to be matched, which makes repair and replacement difficult and maintenance inconvenient. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a diesel engine water circuit connector, which solves the technical problem that most current diesel engine water-cooled diesel engine water circuit connectors are integrated with the water pipe. If the connector or water pipe fails, a matching whole cooling water pipe of the same size and shape is required, resulting in poor repair and replacement capabilities and inconvenient maintenance.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A diesel engine water circuit connector includes a main pipe, a secondary pipe fixedly installed on the side end of the main pipe, a snap-fit ​​groove on the main pipe, a snap-fit ​​spring installed in the snap-fit ​​groove for fixing, an O-ring seal installed inside the main pipe, and a retaining ring installed inside the main pipe.

[0012] Preferably, the inner wall of the main tube is provided with a raised ring.

[0013] Preferably, the convex ring is located inside the slot.

[0014] Preferably, the central axis of the secondary tube and the central axis of the primary tube form a 44-degree angle.

[0015] Preferred option: A reinforcing rib is installed between the main pipe and the auxiliary pipe.

[0016] Preferably, the secondary pipe has a hoop groove.

[0017] Preferably, the main body is internally fixed with a stainless steel liner for structural reinforcement.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The top of the main pipe is mounted on the diesel engine water inlet, and the bottom of the main pipe is connected to the water inlet pipe.

[0027] This application provides a diesel engine water circuit connector, which effectively solves the technical problem that most current diesel engine water-cooled diesel engine water circuit connectors are integrated with the water pipe. If the connector or water pipe fails, a matching whole cooling water pipe of the same size and shape is required, resulting in poor repair and replacement capabilities and inconvenient maintenance. The top of the main pipe is mounted on the diesel engine water inlet, and the bottom of the main pipe is connected to the water inlet pipe. The oil cooler return pipe is connected to the auxiliary pipe. During maintenance, it is only necessary to loosen these three points, replace the water circuit connector assembly, and then tighten the three interfaces on the water circuit connector assembly to the pipe. This reduces maintenance costs and achieves the effect of convenient maintenance.

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application effectively solves the technical problem that most water-cooled diesel engine water circuit joints are integrated with the water pipes. If the joint or water pipe fails, a matching whole cooling water pipe of the same size and shape is required, resulting in poor repair and replacement capabilities and inconvenient maintenance. The overall idea is as follows:

[0030] To address the problems existing in the prior art, this utility model provides a diesel engine water circuit connector, including a main pipe 1, a secondary pipe 2 fixedly installed on the side end of the main pipe 1, a snap-fit ​​groove 3 opened on the main pipe 1, a snap-fit ​​spring 4 for fixing installed in the snap-fit ​​groove 3, and an O-ring seal 5 installed inside the main pipe 1.

[0031] The main pipe 1 has a retaining ring 6 installed inside, and a slot 7 is provided on the retaining ring 6. The inner side wall of the main pipe 1 is provided with a protruding ring 8, which is located inside the slot 7.

[0032] The central axis of the secondary pipe 2 and the central axis of the main pipe 1 form a 44-degree angle. A reinforcing rib 11 is installed between the main pipe 1 and the secondary pipe 2. A hoop groove 12 is opened on the secondary pipe 2. A stainless steel liner 9 for reinforcing structure is fixedly installed inside the main pipe 1.

[0033] Main pipe 1: As the main body of the water connection, the top end is connected to the diesel engine water inlet and the bottom end is connected to the water inlet pipe. It is the key and core load-bearing part. It has a snap-fit ​​groove 3 to provide an installation position for the snap ring 4. It internally accommodates components such as O-ring seal 5 and retaining ring 6. During pouring, a stainless steel liner 9 is built in and used with clamps to fix the water inlet pipe and strengthen its own structural strength.

[0034] Sub-pipe 2: Fixed to the side end of main pipe 1, forming a 44-degree angle with the central axis of main pipe 1, connecting to the oil cooler return water pipe, with a 37-degree chamfer at the end for easy insertion of the return water pipe, and equipped with a hoop groove 12, with the return water pipe opening fitted above the hoop groove 12 and fixed by a clamp to prevent the return water pipe from falling off; the reinforcing rib 11 between main pipe 1 and sub-pipe 2 enhances the strength of the connection between the two and improves the service life of the joint.

[0035] Snap-fit ​​slot 3: It is opened on the main pipe 1 to provide an installation position for the snap ring 4, so that the snap ring 4 can be fitted on it and thus lock the diesel engine interface in the main pipe 1.

[0036] Snap ring 4: Installed in snap-fit ​​slot 3 for fixing. After the diesel engine water inlet is inserted into the top of the main pipe 1, snap ring 4 is put on the snap-fit ​​slot 3 and the two ends are tightened. The diesel engine interface is clamped through the snap-fit ​​slot 3 to prevent it from falling out of the main pipe 1.

[0037] O-ring 5: Placed inside the main pipe 1, when the diesel engine water inlet is inserted into the top of the main pipe 1, it fills the space between the water inlet and the inner wall of the main pipe 1 to achieve a seal and prevent leakage.

[0038] Retaining ring 6: Installed inside the main pipe 1, it engages with the inner wall protrusion ring 8 of the main pipe 1 through its own groove 7 to limit the position of the O-ring 5, ensuring the stability of the O-ring 5 position and the sealing effect;

[0039] Slot 7: It is opened on the retaining ring 6 and works with the protruding ring 8 on the inner side wall of the main pipe 1 to complete the installation and positioning of the retaining ring 6 in the main pipe 1, and to assist in limiting the O-ring seal 5.

[0040] convex ring 8: It is located on the inner side wall of the main pipe 1 and in the slot 7. It cooperates with the slot 7 to realize the installation and positioning of the retaining ring 6 and help the retaining ring 6 limit the O-ring seal 5;

[0041] Stainless steel liner 9: The main pipe 1 is directly embedded during the pouring process. When the water inlet pipe is fixed with clamps, the structural strength of the main pipe 1 is enhanced to prevent damage to the joint body when the clamps are tightened.

[0042] Reinforcing rib 11: Located between the main pipe 1 and the secondary pipe 2, it strengthens the connection between the two and extends the service life of the joint;

[0043] Groove 12: It is opened on the secondary pipe 2. When the return water pipe is fitted onto the secondary pipe 2, the pipe opening is placed above the groove 12. When the clamp is fixed, the return water pipe is pressed into the groove 12 to prevent the return water pipe from falling off the secondary pipe 2.

[0044] Working principle:

[0045] The first step is to insert the diesel engine's water inlet into the maximum position through the opening at the top of the main pipe 1. At this time, the O-ring 5 will fill the space between the diesel engine's water inlet and the inner wall of the main pipe 1 to seal it. Then, the retaining ring 4 is put on the snap-fit ​​groove 3, and the two ends of the retaining ring 4 are pulled tight and fixed. At this time, the retaining ring 4 will clamp the diesel engine interface inside the main pipe 1 through the snap-fit ​​groove 3 to prevent it from falling off. Then, the oil cooler return pipe is put on the secondary pipe 2. The end of the secondary pipe 2 has a 37-degree chamfer, which is conducive to the insertion of the return pipe. The pipe opening of the return pipe is put on the top of the clamp groove 12, and then fixed with the clamp. The clamp will press the return pipe into the clamp groove 12 to prevent it from falling off. Then, the water inlet pipe is put on the bottom of the main pipe 1, and then fixed with the clamp to complete the installation.

[0046] In the second step, the stainless steel liner 9 inside the main pipe 1 is directly installed inside the main pipe 1 during the pouring process. When the clamps fix the water inlet pipe, they can enhance the structural strength. The reinforcing rib 11 enhances the strength of the connection between the secondary pipe 2 and the main pipe 1, and improves the service life. The retaining ring 6 is installed inside the main pipe 1 through the cooperation of the groove 7 and the convex ring 8, and plays a limiting role for the O-ring seal 5.

[0047] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
