Description

Overpressure self-closing leakage-proof plastic hose joint

Technical Field

The invention relates to the technical field of pipe joints, in particular to an overpressure self-closing leakage-proof plastic hose joint.

Background

Plastic pipes are generally produced by extruding synthetic resins, i.e. polyesters, as raw materials in a pipe-making machine by the "plastic" method with the addition of stabilizers, lubricants, plasticizers, etc. The pipe is mainly used as a running water supply system pipe, a drainage, exhaust and pollution discharge sanitary pipe, an underground drainage pipe system, a rainwater pipe, a threading pipe for electric wire installation and assembly sleeve and the like of a house building.

Plastic hoses are one type of plastic tube and are commonly used for water supply, gas supply, and the like. When the plastic hose is connected with the water outlet through the pipe joint, the pipeline of the water outlet is usually a hard pipe, the connection between the pipe joint and the hard pipe of the water outlet is relatively firm, and the connection between the plastic hose and the pipe joint is relatively weak due to easy deformation.

The coupling among the prior art when connecting plastic hose and delivery port hard tube, easily because of water pressure is too big, lead to the junction of plastic hose and coupling to take place to leak, when serious, can make plastic hose drop from the coupling even, lead to leaking in a large number, cause the serious waste of water resource. Therefore, we propose an overpressure self-closing leak-proof type plastic hose connector.
