Further, described joint valve inner tube is provided with annular groove in top, is provided with O-ring seal in annular groove, and O-ring seal is placed in treats gas ducting outside.
Further, in described joint valve inner tube, be provided with the sheet rubber that has through hole, treat that gas ducting bottom is placed on sheet rubber, sheet rubber has two end blocks that extend laterally.
Further, in described joint valve inner tube, have two symmetrical apertures, the end block of sheet rubber is placed in the aperture of joint valve inner tube, when when gas ducting bottom is placed on sheet rubber, sheet rubber, under treating that gas ducting pushes, makes in the end block retraction joint valve inner tube of both sides.
Further, have two symmetrical apertures on described sleeve pipe, the aperture on sleeve pipe is positioned at the outside of the aperture of joint valve inner tube.
The quick pressurize joint of the present invention, simple in structure, adaptability is wider, can be widely used in the tubing processing technique field such as refrigerating evaporator.
Accompanying drawing explanation
For the ease of it will be appreciated by those skilled in the art that the present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of sheet rubber.
Embodiment
Refer to Fig. 1 and 2, joint valve inner tube 9, bottom is communicated with air intake valve, is provided with for treating the through hole that gas ducting 14 inserts in joint valve inner tube 9.
Sleeve pipe 6, is placed on joint valve inner tube 9, and sleeve pipe 6 inside top are provided with screw thread, and sleeve pipe 6 both sides, bottom are connected with joint valve inner tube 9 by two ear shape links 8.
Be U-shaped revolving part 7, both sides are hinged with ear shape link 8 (articulating point is eccentric position) respectively, along with the rotation of revolving part 7, make relative position between sleeve pipe 6 and joint valve inner tube 9 change (being that sleeve pipe 6 moves up and down in joint valve inner tube 9 outsides).Thereby make each parts in quick pressurize joint connect compactness, to guarantee treating that gas ducting 14 can be clamped spacing.
Be placed in the fastening piece 13 at sleeve pipe 6 tops, fastening piece 13 outsides have screw thread, and fastening piece 13 is connected with sleeve pipe 6 screw top.
The composite card external member consisting of fastener 12 and external member 11, is placed between fastening piece 13 inside top and joint valve inner tube 9 tops, and fastener 12 bottoms and external member 11 inside all have the tapered end face matching, and fastener 12 is provided with two symmetrical hollow slots 15.Under the effect of the power of being squeezed, by two symmetrical hollow slots 15, cut apart and be two-part fastener 12, under external member 11 tapered end faces spacing, to fastener 12 inner sides extruding, thereby clamp through wherein treat gas ducting 14.
Treat gas ducting 14, from top to bottom successively through fastening piece 13 and composite card external member, and stretch in the through hole of joint valve inner tube 9.
In order further to improve sealing, in joint valve inner tube 9 tops, be provided with annular groove, in annular groove, be provided with O-ring seal 10, O-ring seal 10 is placed in treats gas ducting 14 outsides.
During installation, revolving part 7, in plumbness, is positioned over O-ring seal 10 in joint valve inner tube 9, then puts into composite card external member, and top screws in fastening piece 13.Then fully insert and treat gas ducting 14, pull revolving part 7, make it just in time be stuck in sleeve pipe 6 outsides, and drive sleeve pipe 6 to move downward, thereby modular card external member and joint valve inner tube 9 are fully compressed, then by the clamping for the treatment of that gas ducting 14 is firm.Open again nitrogen valve, treat gas ducting 14 and inflate.
In addition, in batch process process, be prone to operator treating that gas ducting 14 does not insert under the situation of joint valve inner tube 9 completely, directly open nitrogen valve, thereby make to treat that gas ducting 14 directly flies out, thereby security incident occurs.So, carry out following technological improvement:
In joint valve inner tube 9, be provided with the sheet rubber 1 that has through hole 2, treat that gas ducting 14 bottoms are placed on sheet rubber 1, sheet rubber 1 has two end blocks 3 that extend laterally.In joint valve inner tube 9, there are two symmetrical apertures 4, the end block 3 of sheet rubber 1 is placed in the aperture 4 of joint valve inner tube 9, when when gas ducting 14 bottoms are placed on sheet rubber 1, sheet rubber 1, under treating that gas ducting 14 pushes, makes in the end block 3 retraction joint valve inner tubes 9 of both sides.
In addition, have two symmetrical apertures 5 on sleeve pipe 6, the aperture 5 on sleeve pipe 6 is positioned at the outside of the aperture 4 of joint valve inner tube 9.
Treat whether gas ducting 14 inserts in joint valve inner tube 9 completely, can directly by the aperture of joint valve inner tube 9, sleeve pipe 6, observe the end block 3 of sheet rubber 1 both sides.
Above content is only to structure example of the present invention and explanation; affiliated those skilled in the art make various modifications to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of invention or surmount this scope as defined in the claims, all should belong to protection scope of the present invention.
