Abstract
The present disclosure provides an ultra-high-pressure hose joint assembly, including joint components and a tube body. The joint component includes: a mandrel, the tube body being sleeved over the outer side of the mandrel, the mandrel being in communication with the tube body; a connector, at least a part of the connector being sleeved on the mandrel; and a positioning element, the positioning element being located at the connection between the mandrel and the connector, and the positioning element being used to restrict the relative position between the connector and the mandrel. The ultra-high-pressure hose joint assembly in the present disclosure solves the technical problem in the related art that ultra-high-pressure hose joint assemblies are prone to joint leakage.
Claims20
An ultra-high-pressure hose joint assembly, comprising joint components and a tube body, wherein each joint component comprises:
- a mandrel, the tube body being sleeved over an outer side of the mandrel, the mandrel being in communication with the tube body;
- a connector, at least a part of the connector being sleeved on the mandrel;
- a positioning element, the positioning element being located at a connection between the mandrel and the connector, the positioning element being used to restrict a relative position between the connector and the mandrel.
An assembly process, characterized by comprising:
- sleeving a connector onto a hose joint main body, so that after the connector and the hose joint main body are sleeved in place, an annular retention channel for installing a positioning element is formed between the connector and the hose joint main body;
- installing the positioning element into the formed annular retention channel;
- injecting rubber into a gap between the connector and the hose joint main body, followed by vulcanization treatment, to obtain an ultra-high-pressure hose joint assembly.
