Abstract
The utility model relates to a plastic tubing connection structure of ball valve, including plastic tubing, connecting pipe and clamp, it is protruding that the outside of connecting pipe free end is equipped with the connecting pipe annular, and the outside of plastic tubing tip is equipped with the annular arch of plastic tubing, and the bellied external diameter of connecting pipe annular is the same with the bellied external diameter of plastic tubing annular, and the annular bellied outer end face contaction of connecting pipe bellied outer terminal surface of annular and plastic tubing, clamp include the clamp recess that is formed by the both sides flange, and the clamp recess matches with connecting pipe annular arch, the annular arch of plastic tubing of contact. Connecting pipe annular is protruding, the plastic tubing in annular bellied end face obliquely set up, the inner wall of flange has and is connected pipe ring, the annular bellied interior terminal surface matched with inclination of plastic tubing. The utility model discloses a cooperation of annular arch and clamp realizes that not only connect convenient and fast, joint support intensity is big, and the size that does not have the design ball valve metalwork of nut moreover need not too greatly, with low costs, and satisfies the great pipe diameter requirement of plastic tubing.
Description
Technical field
This utility model is related to a kind of ball valve attachment structure, more particularly to a kind of plastic tube bindiny mechanism of ball valve, belongs to
Ball valve of pipeline interconnection technique field.
Background technology
Metal tube intensity height is easy to connect extensively to be applied in the pipelines such as water, oil, but metal tube price is high and uses process
Get rusty easily corrosion；Therefore select plastic tube, plastic tube that there is preferable tension, resistance to compression in existing liquid conducting pipes system more
The advantages of intensity, environmental protection, little fluid resistance, liquid conducting pipes system, do not only have plastic tube and have control valve, such as ball valve, ball valve
The nut being connected with connecting tube including valve body, the connecting tube being connected as a single entity with valve body positioned at valve body two ends and by screw thread, valve body,
Nut is metalwork, and it is now to back out nut that existing ball valve is connected with plastic tube, and plastic tube passes through nut, plastics tube end
Flanging is coordinated with the end face of nut, and then nut is threadedly coupled with connecting tube, and this connected mode will be arranged due to plastic tube
Flanging, in order to ensure the support strength of flanging, the external diameter of usual flanging is more much larger than the internal diameter of plastic tube, larger external diameter
Flanging result in nut internal diameter it is big, and the external diameter of the connecting tube being engaged with nut increase, this connected mode is not
But increase the cost of ball valve, and the often larger less plastic tube of ball valve connection internal diameter, limit liquid conveying system
The flow and flow efficiency of liquid.
Utility model content
This utility model is in view of the shortcomings of the prior art, there is provided a kind of simple structure, easy to connect, low cost, protects
The plastics pipe connecting structure of the ball valve of the bonding strength of card plastic tube and ball valve.
The technical scheme that this utility model solves above-mentioned technical problem is as follows：A kind of plastics pipe connecting structure of ball valve, bag
Include plastic tube, be arranged on the connecting tube and the clip for connecting plastic tube and connecting tube of valve end, the connecting tube freedom
Connecting tube annular protrusion is provided with the outside of end, plastic tube annular protrusion, the connecting tube on the outside of the plastics tube end, is provided with
The external diameter of annular protrusion is identical with the external diameter of the plastic tube annular protrusion, the outer face of the connecting tube annular protrusion with it is described
The outer face contact of plastic tube annular protrusion, the clip include the clip recess formed by both sides rib, the clip recess
It is engaged with the connecting tube annular protrusion, plastic tube annular protrusion that contact.
The beneficial effects of the utility model are, the cooperation reality for being connected by annular protrusion and clip of ball valve and plastic tube
Existing, not only convenient and fast connection, connection support strength is big, and does not have the size of the design ball valve metalwork of nut without the need for too
Greatly, low cost, and meet the larger caliber requirement of plastic tube.
On the basis of above-mentioned technical proposal, this utility model can also do following improvement.
Further, sealing gasket is provided between the connecting tube and the plastic tube.
It is to strengthen the connection sealing of connecting tube and plastic tube using the beneficial effect of above-mentioned further scheme.
Further, the sealing gasket is arranged in facing groove, and the facing groove is arranged on the connecting tube annular
On the outer face of raised outer face and/or the plastic tube annular protrusion.
It is that sealing gasket is easy for installation using the beneficial effect of above-mentioned further scheme, sealing gasket is positioned, it is to avoid close
There is play and seals not good situation in packing.
Further, the connecting tube annular protrusion, the inner face of plastic tube annular protrusion are obliquely installed, the rib
Inwall is with the angle of inclination being engaged with the inner face of the connecting tube annular protrusion, plastic tube annular protrusion.
It is that clip positioning is efficient and convenient and accurate, is easy to the installation of clip using the beneficial effect of above-mentioned further scheme
And ensure the sealing of plastic tube and ball valve.
