Abstract
The utility model relates to a connecting pipe for pipe joints, which mainly solves the problem that O-shaped ring is impacted by pipeline hydraulic pressure. The utility model is a tubular body with a circular cross-section and one end provided with a radical flange, and the utility model is characterized in that the inner edge of an end surface of the flange is provided with a circle of axial dummy club. The utility model is suitable for being connected with the joint of JB966 type standard pipes.
Description
The utility model relates to the connecting tube of pipe joint.
The connecting tube of pipe joint is a circular section shape tubular body that radial flange is at one end arranged, and the cylindrical tube pipe shaft is adopted in the connecting tube that common steel pipe is used, and circular cone nodular pipe shaft is adopted in the connecting tube that flexible pipe is used.When the plane of connecting tube flange front end and fittings body close up, 0 RunddichtringO between its end face still be exposed to pipeline middle, directly bear hydraulic shock in the pipeline, therefore the operating life of 0 type circle is very short, take place at pipeline under the situation of instantaneous high speed flow, 0 type circle is subjected to suction function to be inhaled into pipeline easily and causes pipeline leakage.
The purpose of this utility model provides a kind of 0 type circle of avoiding and is subjected to the connecting tube that hydraulic pressure directly impacts in the pipeline.
The utility model is a circular section shape tubular body that radial flange is at one end arranged, and it is characterized in that there is the axial boss of a circle on the interior edge of flange end face.
Because the utility model has the axial boss of a circle on the interior edge of flange end face, stopped that liquid stream not only can prolong the working life of 0 type circle to the impact of 0 type circle in the pipeline, can prevent that also O type circle is inhaled into pipeline.
The explanation of accompanying drawing drawing: accompanying drawing 1 is the utility model has straight shape boss at the flange of cylindrical tube pipe shaft one end a schematic representation; Accompanying drawing 2 is the utility model has cone boss at the flange of cylindrical tube pipe shaft one end schematic representation; Accompanying drawing 3 is the utility model has straight shape boss at the flange of circular cone nodular pipe shaft one end schematic representation; Accompanying drawing 4 is the utility model has cone boss at the flange of circular cone nodular pipe shaft one end schematic representation; In the accompanying drawing 1 expression pipe shaft, 2 expression flanges, 3 expression boss.
Realize that best way of the present utility model is that the cylinder of boss 3 is vertical with the end face of flange 2, perhaps the outer cylinder of boss 3 is made taper type.The utility model be suitable for linking to each other with the fittings body of JB966 type standard pipe joint by.
