Problems solved by technology
This method is widely used because of its good sealing performance, but it requires a large installation space, and is not suitable for small spaces; method 2: ball joint connection, when using this method, the ball joint and the pipeline need to be welded Together, the pipeline welded with the ball joint is installed on the parts to be lubricated through the pipe connection screw and the sealing ring. This method is widely used because of its low cost, but for the pipeline with a complex space structure, it is often used after welding. Spatial misalignment occurs, difficult adjustments bring difficulties to installation, and require high technical level of operators

The invention belongs to the technical field of pipe connection and relates to a combined sealing pipe connector and a using method of the combined sealing pipe connector. The combined sealing pipe connector comprises a connector body, a pipe connector nut (3), a ferrule (2), a seal ring I (6), a seal ring II (8) and a hollow pipe connector bolt (5). The connector body is provided with a connector body I (1) and a connector body II (9), wherein the connector body I (1) and the connector body II (9) are perpendicular to each other and are respectively provided with a center hole. The hollow pipe connector bolt (5) is inserted in the center hole of the connector body I (1), a gap is formed between the hollow pipe connector bolt (5) and the inner wall of the connector body I (1), and the sealing pipe connector and a part (7) which needs lubricating are connected into a whole through the hollow pipe connector bolt (5). The combined sealing pipe connector has the advantages that the requirement for the size of installation space is not high; the structure is simple, and machining cost is low; the connector body can rotate 360 degrees around the pipe connector bolt, the direction of a pipe can be adjusted and changed according to the space demand of the pipe, and the requirement for the technical level of an operator is low.
Description
technical field [0001] The invention belongs to the technical field of pipe connection, and relates to a combined sealing pipe joint and a use method. Background technique [0002] In order to improve the service life of diesel engine fresh water pumps, sea water pumps, high pressure oil pumps, superchargers and other components, and reduce the occurrence of failure rates, these components need to be lubricated forcibly during the operation of the diesel engine, that is, the main parts of the diesel engine are lubricated through the pipeline. The lubricating oil channel is connected with the parts to be lubricated. There are generally threaded holes reserved on the parts that need to be lubricated. There are usually two ways to connect the parts that need to be lubricated and the pipeline of the diesel engine: ferrule-type pipe joint connection and ball joint pipe connection. Method 1: ferrule-type pipe joint connection, that is, relying on the thread tightening force betwe...
