Gas meter flat wire sealing assembly

Abstract

The invention provides a gas meter flat wire sealing assembly which is provided with a flat wire penetrating through the inside and the outside of a meter case. An adapter with a stopping platform and an axial taper hole is plugged in a through hole of the meter case, the two ends of the adapter are located inside and outside the meter case respectively, a cover of the adapter is provided with an axial perforation hole, the upper end face of the adapter is provided with a stair platform matched with the cover of the adapter, a conical rubber plug is inserted in the axial taper hole of the adapter, the top end of the conical rubber plug is provided with a conical platform at an angle ranging from 10 degrees to 15 degrees, the cover of the adapter is provided with an assembling boss matched with the stair platform, the inside of the assembling boss is provided with an assembling groove matched with the conical platform, the top of the outer end face of the conical rubber plug is provided with a washer of the axial perforation hole, and the cover of the adapter is matched with the adapter to be fixed in the meter case. The gas meter flat wire sealing assembly saves time and labor during assembling, high in sealing reliability and long in service life; the whole area of the assembly is reduced through the flat wire.

Description

technical field [0001] The invention relates to a sealing structure assembly, in particular to a gas meter flat wire sealing assembly. Background technique [0002] IC card gas meter is an intelligent gas meter, which integrates automatic metering and billing. It is a new type of gas meter recently launched, which integrates functions such as gas channel gas and valve opening and closing. This kind of gas meter needs to have wire to run through the inside and outside of the watch case; the place where the wire runs through the watch case must have reliable sealing to stop the gas leakage in the meter. The method of preventing gas leakage in the known prior art is as figure 2 As shown, a threading splint 23 is provided at the threading hole where the wire 21 runs through the watch case 22 to prevent gas leakage, and there is a sealant-coated groove 24 inside the watch case; the disadvantage is that the process is complicated, and the product must be glued. Leaving it for a...

The method of preventing gas leakage in the known prior art is as figure 2 As shown, a threading splint 23 is provided at the threading hole where the wire 21 runs through the watch case 22 to prevent gas leakage, and there is a sealant-coated groove 24 inside the watch case; the disadvantage is that the process is complicated, and the product must be glued. Leaving it for a period of time will affect the production, and the exposed sealant is easy to age, loosen and cause leakage
