Description

Technical Field

[0001] This application relates to the field of diesel engine technology, specifically to a diesel engine water inlet bend. Background Technology

[0002] A diesel engine, or simply diesel engine, is a compression-ignition internal combustion engine that uses diesel fuel. It generally consists of an engine block, crankshaft and connecting rod mechanism, valve train, fuel system, lubrication system, cooling system, and starting system.

[0003] For example, Chinese utility model patent publication number "CN217999706U" discloses a water inlet bend for a diesel engine. This utility model uses a connecting block to move a moving block and a locking block, installing the filter assembly in the mounting groove. Releasing the connecting block causes a spring to move the moving block and locking block, installing the filter assembly through the mounting groove onto the circular plate. The circular plate is tightly fitted against one side of the water inlet bend body. A buffer bend extends into the interior of the water inlet bend body, with a buffer sleeve tightly fitted against the bend of the water inlet bend body. Bolts pass through mounting holes on the water inlet bend body and the circular plate, fixing the buffer assembly to the water inlet bend body. The water inlet bend body is then bolted to the diesel engine... The engine block is connected. When the diesel engine needs cooling, the water pump sends water from the water tank into the inlet bend. The water flows through the filter assembly, where the filter screen filters impurities. When the water flows through the buffer bend, the spiral on the inner wall of the buffer bend turns the water flow into a spiral flow, preventing the water from contacting the bend of the inlet bend. The buffer sleeve contacts the inner wall of the bend of the inlet bend, buffering the flow between the buffer bend and the inlet bend. The filter assembly can be removed from the mounting slot periodically by disassembling the inlet bend, snapping on the connecting block, and moving the connecting block and the locking block. The filter screen can then be cleaned.

[0004] The aforementioned patent can filter water flow and provide a certain degree of buffering at the bends of the pipes. However, after prolonged use, under the long-term vibration of the engine, the screws are prone to loosening, which can damage the initial sealing state of the connection and cause coolant to leak from the gaps under pressure, affecting the sealing performance.

The connecting mechanism comprises a mounting plate and a rubber plate, the mounting plate being mounted at both ends of the bend, and the rubber plate being fixedly mounted at one end of the mounting plate.

[0009] By adopting the above technical solutions, the connecting mechanism can reduce vibration transmission and enhance sealing, effectively preventing loosening and leakage caused by long-term vibration. The filter buffer mechanism facilitates the installation and removal of the filter box, makes cleaning or replacement of the filter box convenient, and provides buffer protection for the bend, reducing vibration damage to the bend.

[0014] Preferably, both the mounting plate and the rubber plate have mounting holes at one end, and the mounting holes penetrate the mounting plate and the rubber plate.

[0015] By adopting the above technical solution, the mounting plate and rubber plate can be fixed to the engine by passing bolts through the mounting holes, thus achieving a firm connection between the bend and the engine.

[0016] Preferably, a guide ring is slidably connected to the inner wall surface of the mounting block, a connecting plate is fixedly installed at one end of the guide ring, and a sealing ring is fixedly installed at one end of the connecting plate.

[0017] By adopting the above technical solution, the sliding of the guide ring on the inner wall of the mounting block can guide the movement of the connecting plate, and the sealing ring can enhance the sealing between the connecting plate and the inner wall of the bend, preventing coolant leakage.

[0018] Preferably, the sealing ring is slidably connected to the inner wall surface of the bend, a filter box is fixedly installed at one end of the connecting plate, and a buffer sleeve is fixedly installed on the surface of the bend.

[0022] 1. This diesel engine water inlet bend, by incorporating a connecting mechanism, solves the problem that in previous water inlet bends were prone to loosening of screws under long-term engine vibration, which could damage the initial sealing of the connection and cause coolant to leak from the gaps under pressure, affecting the sealing performance. It achieves the beneficial effects of reducing vibration transmission and enhancing sealing, effectively avoiding loosening and leakage caused by long-term vibration.
