Examples

As shown in fig. 1 to 6, the main structure of an integrated pipeline with a one-way ventilation function is a nylon pipeline 1, a one-way valve 2 and a quick connector 3. The nylon pipeline 1 is clamped and fixed through a pipe clamp. The check valve 2 and the nylon pipeline 1 are pressed and mounted, and a sealing ring is arranged on the check valve 2 and matched with the nylon pipeline to realize sealing. The check valve is generally matched with a nylon pipeline with the inner diameter of phi 8 mm.

The quick connector 3 is pressed with the nylon pipeline 1, and the sealing ring is arranged on the quick connector 3 and matched with the nylon pipeline to realize sealing. The quick connector 3 is generally matched with a nylon pipeline with the inner diameter of 6 mm.

The integrated pipeline is connected with a transmission system part through a quick plug connector 3, and the quick plug connector 3 is of a right-angle quick plug structure and is generally connected with a vertical metal pipeline with the external diameter of phi 8 mm. The vertical metal pipe is generally arranged on the uppermost surface of a transmission system component (the transmission system component can be a speed changer, a transfer case, a main speed reducer and the like), the structure is simple, the peripheral whole vehicle parts are numerous, the installation and operation space is small, the quick-plug connection mode is simple and convenient to operate, the required space is small, and the problem is perfectly solved.

The check valve 2 comprises a valve body, a cover plate, a spring and a dust cap, the valve body is clamped with the dust cap, and the spring is abutted between the cover plate and the dust cap. The spring props against the cover plate and the dustproof cap to keep the cover plate and the dustproof cap in a normally closed state, so that dust and water are prevented from entering the nylon pipeline. When the air pressure in the transmission system part rises, the oil gas reaches the vent valve through the nylon pipeline, and when the air pressure is higher than a certain value, the cover plate is pushed open to realize ventilation, and after the air pressure is reduced, the cover plate returns under the action of the spring, so that the oil gas is waterproof and dustproof.

the nylon pipeline and the one-way valve metal pipe are pressed, the process is simple, the operability is high, and most of the time, the spring extends to prop against the cover plate and the dustproof cap, so that the cover plate and the dustproof cap are kept in a normally closed state, and dust and water are prevented from entering the nylon pipeline. When the air pressure in the transmission system component rises, the spring is compressed, the cover plate is finally jacked open, air comes out from the pipeline and passes through the gap between the lower baffle plate and the dustproof cap, ventilation with the outside is realized, the air pressure for jacking the cover plate is related to the rigidity of the spring, and the larger the rigidity of the spring is, the larger the required air pressure is. When the internal air pressure is reduced, the cover plate returns under the action of the spring to cover the vent valve pipeline, so that dust prevention and water prevention are realized.
