The connection set (application number: 201010577999.8 applyings date: 2010-12-08) of a kind of full-diameter compressed air conveying pipeline of Chinese invention patent; the connection set of full-diameter compressed air conveying pipeline; this device is made up of metal shell body and seal arrangement; the inner chamber of metal shell body is provided with annular mounting groove, and the both sides of annular mounting groove are respectively equipped with annular slope; Seal arrangement is made up of annular frame, two pressure rings and two " O " shape seal rings, two pressure rings are movably set in respectively the both sides of annular frame, pressure ring shoulder is respectively equipped with annular slope, " O " shape seal ring is separately positioned on the corner part of pressure ring inner ring, and two ends of annular frame offset with " O " shape seal ring respectively; And, be provided with annular cambered surface or annular slope is excessive at the corner part of pressure ring inner ring, or be respectively equipped with the 3rd annular slope in the inner side, two ends of annular frame.The present invention goes for major diameter pipeline and connects, and has simple in structurely, and it is convenient to implement, the feature being connected firmly.But the sealing device structure complexity of this device, production cost is higher.
Summary of the invention
The technological deficiency existing in order to solve Chinese invention patent (application number: 201010577999.8 applyings date: 2010-12-08), the object of this invention is to provide a kind of seal element for compressed air line connection set, sealing element has simple in structure, it is convenient to implement, the feature of better tightness.
In order to realize above-mentioned object, what the present invention adopted is following technological scheme.
A kind of seal element for compressed air line connection set, sealing element adopts quality of rubber materials or flexible plastic material, seal element comprises annular solid and two seal rings, the external diameter of annular solid and described annular mounting groove diameter are suitable, two seal rings are arranged on the two ends of annular solid, in seal ring, turn at outer side surface and be formed with the first annular slope, the first annular slope is horn-like by the outside toe-in of seal ring, the inner end of the first annular slope forms ring packing lip, the diameter of ring packing lip is less than or equal to the external diameter of compressed air line.
As preferably, in the middle of the inner ring of described annular solid, be provided with position limiting convex ring, the internal diameter of position limiting convex ring is greater than the external diameter of compressed air line.
The present invention is owing to having adopted above-mentioned technological scheme, when use, two pipe fittings of pipe fitting are inserted into respectively in seal element, then can pass through first watt of type body of locking member and second watt of type body, first watt of type body and second watt of type body press seal element make the ring packing lip distortion on seal ring, make like this first annular chamfered portion or whole gluing, sealing compressed air hose pipeline outer wall, formed good sealing effect.Meanwhile, due to seal element adopt quality of rubber materials or flexible plastic material one-body molded, make the structure of product more simple, reduced production cost.
