When matching high-pressure steel wire braided rubber hose joints with other equipment, ensuring the sealing between hydraulic hoses and rubber hoses is a key step. Let's briefly take a look at the connection form of high-pressure rubber hoses and the precautions for conical sealing.

1、 Hose joints can be roughly divided into internal threads and external threads.

1) Internal thread form

This structure is generally suitable for situations with relatively low working pressure and high flow rate. This connection method allows for an appropriate increase in the diameter of the hose, and its tightness mainly depends on the sealing ring. The internal and external threads of the quick connector must be connected to the rubber hose using a transition joint or adapter.

2) External thread form

This structure is mainly used under high pressure, especially when the working pressure exceeds 1800 bar. In this connection method, the locking nut is compressed by the external threaded connector, causing the conical sealing surface of the pipe section to tightly fit with the sealing surface of the connector, providing a sealing effect. The connected components can also be spray accessories, such as high-pressure spray guns, flat cleaning nozzles, 3D rotating nozzles, etc. This connection method can effectively prevent loose connections under complex construction conditions.

2、 Precautions for Cone Sealing of High Pressure Steel Wire Braided Rubber Hose Assembly

1) The cone angle of this connection is 60 degrees, and the cone angle of the pipe end is generally less than 1 degree of the cone angle of the hole;

2) The position of the pipe end must be kept sharp and not blunt;

3) The thread direction between the pipe end and the locking nut should be opposite to the external thread joint;

4) When processing joints, drainage holes should be reserved at the sealing area to prevent high-pressure water from leaking out when the conical surface seal is not tight. This can serve as a safety warning and facilitate observation and judgment, thereby better protecting the sealing surface from damage.

Regardless of the variety of high-pressure steel wire braided rubber hose joints, the selection of how to use transition joints should be based on the type of hose joint. If the hose is a regular water pipe, a transition joint should be used, with one end having internal teeth and the other end being a water pipe, and then fixed with a hose clamp. If the two ends of the hose have internal teeth, a transition joint connection should be used, with one internal tooth and one external tooth. If the two ends of the hose have external teeth, a transition joint and internal teeth must be used to connect them.
