The gas meter, flow meter of current most of family has been updated to IC-card intelligent gas meter, this gas meter, flow meter need wire pass through connection watchcase inside and outside, its wire runs through watchcase place must have reliable sealing to stop the gas leakage in table.
Summary of the invention
For solving the problems of the technologies described above, the intelligent gas meter wire hermetically-sealed construction that the utility model provides, prevents from showing interior gas leakage, good seal performance.
The technical scheme that the utility model adopts is: a kind of intelligent gas meter wire hermetically-sealed construction, comprise the watchcase of middle part with through hole, inner nut, T-connecting piece, cone seal plug, gland, wire, the T-connecting piece that inside arranges axial taper hole is equipped with in the through hole of described watchcase, described T-connecting piece comprises appear on the stage part and leave from office part, cone seal plug is plugged with in described T-connecting piece taper hole, the little one end of described cone seal plug area is towards T-connecting piece, the splayed groove of opening towards cone seal plug large area one end is provided with in one end that described cone seal plug area is little, the outward flange of the part of appearing on the stage of described T-connecting piece is covered with gland, one end that described cone seal plug area is large is located in described gland, O-ring seal is provided with between described gland and described cone seal plug, fixed by the first bolt between described T-connecting piece and described gland, the leave from office part of described T-connecting piece is located in described inner nut, fixed by the second bolt between described inner nut and described T-connecting piece, described wire is arranged on the position, axis of hermetically-sealed construction, and run through gland, cone seal plug, T-connecting piece, inner nut.
Described cone seal plug is two parts composition of half cone-shaped.
Angle а between the axis of described splayed groove and described cone seal plug is 10 degree to 30 degree.
Appearing on the stage partly and arranging O shape between described watchcase of described T-connecting piece is enclosed.
The beneficial effects of the utility model are: adopt the sealing-plug of two half cone-shaped by conductor clamping, fill in T-connecting piece, and with the gland of watchcase outside and the inner nut of watchcase inside, cone seal plug and T-connecting piece are clamped, ensure that the effect of sealing, be provided with the splayed groove of opening towards cone seal plug large area one end in one end that cone seal plug area is little simultaneously, if there is gas to be leaked in sealing-plug in wire guide, gas enters umbrella shape groove, produce one outside watchcase and to the pressure of axis, watchcase inward-outward direction has been bolted tightly, counteract to the pressure outside watchcase, sealing-plug is compressed guiding line by pressure to axis further, ensure the sealing of wire, make gas can not to outward leakage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1. cone seal plug, 2. gland, 3.T shape web member, 4. watchcase, 5. splayed groove, 6. inner nut, 7.O shape is enclosed, 8. O-ring seal, 9. the second bolt, 10. the first bolt, 11. wires.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, a kind of intelligent gas meter wire hermetically-sealed construction, comprise the watchcase 4 of middle part with through hole, inner nut 6, T-connecting piece 3, cone seal plug 1, gland 2, wire 11, the T-connecting piece 3 that inside arranges axial taper hole is equipped with in the through hole of watchcase 4, T-connecting piece 3 comprises appear on the stage part 12 and leave from office part 13, cone seal plug 1 is plugged with in T-connecting piece 3 taper hole, cone seal plug 1 is two parts composition of half cone-shaped, the little one end of cone seal plug 1 area is towards T-connecting piece 3, the splayed groove 5 of opening towards cone seal plug 1 large area one end is provided with in one end that cone seal plug 1 area is little, angle а between the axis of splayed groove 5 and cone seal plug 1 is 10 degree to 30 degree, the outward flange of the part 12 of appearing on the stage of described T-connecting piece 3 is covered with gland 2, one end that cone seal plug 1 area is large is located in gland 2, O-ring seal 8 is provided with between gland 2 and cone seal plug 1, fixed by the first bolt 10 between T-connecting piece 3 and gland 2, the appearing on the stage of T-connecting piece 3 arranges O shape between part 12 and watchcase 4 and encloses 7, the leave from office part 13 of T-connecting piece 3 is located in inner nut 6, fixed by the second bolt 9 between inner nut 6 and T-connecting piece 3, wire 11 is arranged on the position, axis of hermetically-sealed construction, and run through gland 2, cone seal plug 1, T-connecting piece 3, inner nut 6.
During assembling, first with two parts of cone seal plug 1, wire 11 is clamped, plug is in T-connecting piece 3, O-ring seal 8 is added outside cone seal plug 1, press gland 2, with the first bolt 10, gland 2 and T-connecting piece 3 are tightened together, fill in the through hole of watchcase 4, watchcase 4 inner with the second bolt 9 by inner nut 6 and T-connecting piece 3 fastening.During use, if there is gas to be leaked in sealing-plug in wire 11 hole, gas enters splayed groove 5, produce one outside watchcase 4 and to the pressure of axis, watchcase 4 inward-outward direction has been bolted tightly, counteracts to the pressure outside watchcase 4, and cone seal plug 1 is compressed guiding line by pressure to axis further, ensure the sealing of wire 11, make gas can not to outward leakage.
