Description
Technical Field
The utility model relates to the field of hydraulic pipelines, in particular to an oil pipe joint.
Background
The oil pipe joint is a part for connecting oil pipes in a hydraulic system. The oil pipe joint is widely applied in the technical field of engineering, such as fuel oil and engine oil pipelines of power machinery, hydraulic oil pipelines of hydraulic machinery and the like. It is often the case that two oil pipes are butted when installing or extending an oil passage, and therefore, it is necessary to install an oil pipe joint connection.
In the use process of the hydraulic machine, the oil pipe joint leaks oil due to the movement and scraping of the machine, so that the hydraulic machine cannot work normally, most of the oil pipe joints used in the current hydraulic machine are sealed by adopting an end face O-shaped sealing ring or a conical surface, and also are sealed by adopting softer metal pads such as copper pads or aluminum pads depending on metal deformation, and the sealing modes are all sealed by adopting pressure sealing, and no matter which mode is adopted, the oil pipe joint leaks oil as long as a locking nut is slightly loosened, the phenomenon not only can pollute the environment, but also can influence normal work, so the oil pipe joint is provided to solve the problems.
Disclosure of utility model
In order to overcome the above-mentioned drawbacks of the prior art, the present utility model provides an oil pipe joint.
The oil pipe joint comprises a first joint, a second joint and a locking nut, wherein the first joint is cylindrical, external threads are arranged on the outer wall of the first joint, the second joint is cylindrical, the outer surface and the end face of the second joint are respectively attached to the inner surface and the end face of the first joint, O-shaped annular grooves are respectively arranged on the outer surface and the end face of the second joint, O-shaped sealing rings are arranged in the O-shaped annular grooves, the locking nut is sleeved outside the second joint, and the internal threads of the locking nut are matched with the external threads of the first joint.
Further, the two O-shaped sealing rings are respectively abutted against the inner wall and the end face of the first joint.
Further, the outer surface of the second connector is provided with an annular bulge, and the annular bulge is arranged below the O-shaped sealing ring far away from one end of the end face of the second connector.
The oil pipe joint has the beneficial effects that in the design scheme of the utility model, the second joint is matched with the first joint, the outer surface and the end surface of the second joint are respectively attached to the inner surface and the end surface of the first joint, the O-shaped ring grooves of the outer surface and the end surface of the second joint are internally provided with the O-shaped sealing rings, and the locking nuts sleeved on the second joint are in threaded connection with the first joint, so that the O-shaped sealing rings are tightly contacted with the first joint, and the oil pipe joint is sealed by the two O-shaped sealing rings, thereby ensuring good sealing, difficult leakage and improved sealing effect.
