Background

When the engine works, a part of combustible mixed gas and waste gas are blown into the crankcase through the piston ring, and fuel steam blown into the crankcase is condensed to dilute the engine oil and deteriorate the performance. The waste gas contains water vapor and sulfur dioxide, the water vapor is condensed in the engine oil to form foam, and the engine oil supply is damaged, and the phenomenon is particularly serious in winter; sulfur dioxide generates sulfurous acid when meeting water, sulfurous acid generates sulfuric acid when meeting oxygen in air, and the occurrence of the acidic substances not only causes the engine oil to deteriorate, but also causes parts to be corroded.

Further, since the combustible mixture and the exhaust gas are blown into the crankcase, the pressure in the crankcase increases, and the engine oil leaks out from the crankshaft oil seal, the crankcase gasket, and the like and is lost. The oil vapor lost to the atmosphere can increase the pollution of the engine to the atmosphere.

This phenomenon can be avoided or reduced by providing the engine with a crankcase ventilation device which recovers a combustible mixture in the blow-by gas, prevents deterioration of engine oil, prevents leakage of a crankshaft oil seal and a crankcase liner, and separates and recovers oil mist entrained in the blow-by gas with an oil-gas separator.

However, in the pipe connection between the engine and the gas-oil separator, a large-diameter joint is often used for connection due to the demand for flow rate or the like. And because engine space is limited, the pipeline joint has higher temperature requirement, and based on this, this document provides a quick connector design scheme.

Description of the drawings:

a joint body 1 and a clamp 2; an O-shaped ring groove 11, a clamping positioning block 12 and a fir tree end 13; a first pressing handle 21, a reinforcing ring 22, a male end matching surface 23, a connector body matching surface 24, a second pressing handle 25 and a claw 26.

Detailed Description

As shown in fig. 1, the utility model provides a large-diameter quick connector, which is divided into a connector body 1 and a clamping clip 2, wherein one end of the connector body 1 adopts a fir tree structure to connect a nylon pipeline, and the other end can be matched with a public end; the clip 2 is fitted on the joint body. The large-diameter quick connector can be conveniently and quickly installed on the male end through the connector body 1, and the clamping method can be adjusted according to the actual assembling position. And as shown in fig. 2, the large-diameter quick connector is easy to disassemble, and the second pressing handle 25 is pushed to push the clamp 2 out of the connector body 1 during disassembly, so that quick disassembly is realized. The design of clamping has the commonality, no matter connects the body and adopts direct joint or elbow joint, all can adopt this clamping structure.
