Outlet line device 1 can comprise assembly department 12 cylindrically and be circular limited part 13.
Particularly, the external diameter of assembly department 12 is less than or equal to mounting hole diameter, and is tightly connected with mounting hole; The through hole (in circular, therefore inside has through hole) of assembly department 12 inside is as wire outlet hole 11, and the axes normal of wire outlet hole 11 is in testpieces wallboard 32.
The internal diameter of limited part 13 equals the external diameter of assembly department 12, is coaxially fixedly installed on the outer ring surface of assembly department 12.Certainly, independent making can be selected between assembly department 12 and limited part 13 to fix again, or adopt integrated formed structure, and integrated formed structure can make stability stronger.
When outlet line device 1 is arranged in mounting hole by assembly department 12 sealing, limited part 13 can play the effect preventing outlet line device 1 from moving axially, and adds strong stability.Further, limited part 13 is that to be positioned at testpieces seal area 31 inner, and is connected with the inner wall sealing of the testpieces wallboard 32 at mounting hole place, can reduce the external member of testpieces wallboard 32, more conveniently tests.
In addition, sealer 2 or seal washer etc. can also be set between limited part 13 and testpieces wallboard 32, sealability can be improved further.
Embodiment 1
As depicted in figs. 1 and 2, in the present embodiment, outlet line device 1 entirety is bolt shape.Outlet line device 1 can comprise a bolt body, and bolt body inside offers coaxial through hole, as wire outlet hole 11.Wherein, the screw section of bolt body is as the assembly department 12 of outlet line device 1, namely bolt body is arranged in the mounting hole of testpieces wallboard 32 by screw section sealing, such as can the screw thread matched be set in mounting hole, can make can be better with the connection sealing of bolt body, and easy installation and removal.The nut of bolt body as the limited part 13 of outlet line device 1, can play position-limiting action.
Described bolt body can also be arranged the nut 4 matched, it is outside that nut 4 is positioned at testpieces seal area 31, and be tightly connected with the outer wall of the testpieces wallboard 32 at mounting hole place.Testpieces wallboard 32, can enhanced leaktightness performance by the nut on bolt body and between nut 4.Equally, sealer 2 or sealing gasket etc. can be also provided with between nut 4 and testpieces wallboard 32 with enhanced leaktightness performance.
Embodiment 2
As shown in figures 1 and 3, be with the difference of described embodiment 1, in the present embodiment, outlet line device 1 entirety is in Flange-shaped Parts, comprises a flange body.Flange has various shape structure, and in the present embodiment, flange is mainly the structural type of the band neck shown in Fig. 3, no longer repeats its structure and other forms of flange arrangement at this.
In the present embodiment, the neck of flange body, as the assembly department 12 of outlet line device 1, is tightly connected with the mounting hole of testpieces wallboard 32.The through hole of flange body inside is as the wire outlet hole 11 of outlet line device 1.And the flange of flange body is as the limited part 13 of outlet line device 1, and, flange is provided with tapped hole, on testpieces wallboard 32, screw can also be set in corresponding position, make to be fixedly connected with testpieces wallboard 32 with the flange of flange body by bolt or rivet, further enhanced leaktightness performance.
The utility model is as follows based on the concrete using process of the outlet line device of above-mentioned two embodiments:
1) number of conductors of, drawing as required determines every dimensional parameters and the external forms such as the aperture of this outlet line device 1.Usually, bolt (band nut) form is selected in small aperture, and form of flanges is selected in relatively large aperture.For 9 core strain measurement wires, the relation between wire radical and wire outlet hole aperture is as follows:
Wire radical=(aperture-10) 2/25;
Thus can according to wire radical determination pore size.
2), by outlet line device good for Choice and process and the wire anhydrous alcohol wiped clean that will pass, guarantee that outlet line device and wire do not have the residues such as greasy dirt.
3), wire is passed outlet line device.
