A gas metering box

Abstract

This utility model discloses a gas metering box, including a metering box body. Both sides of the metering box body have through-holes for pipes. Sealing sleeves are provided on both the inner and outer sides of the through-holes. The sealing sleeves are fixedly connected to the metering box body by adhesive. The end of the sealing sleeve furthest from the metering box body is inclined inwards, and the edge of this end of the sealing sleeve is turned outwards at a 45-degree angle. A restraining ring is fitted on the outer side of this end of the sealing sleeve. The advantage of this utility model is that by using the sealing sleeve to fit against the outer surface of the gas pipe installed through the through-hole, the gap between the gas pipe and the through-hole is sealed, thus preventing external dust and moisture from entering the metering box body. This seal also prevents the pipes and gas meter installed inside the metering box from being corroded by dust and external moisture.

Description

Technical Field

[0001] This utility model relates to the field of gas metering box technology, and in particular to a gas metering box. Background Technology

[0002] A metering box is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy. It includes electricity meters, voltage and current transformers and their secondary circuits, electricity metering panels, cabinets, boxes, etc. A gas metering box is a metering device that integrates multiple gas metering and pressure regulating devices. It is mainly used in gas pressure regulating and distribution systems. A gas metering box typically includes components such as gas pressure regulators, filters, safety accessories, control equipment, flow meters, and IC card controllers.

[0003] However, in the existing technology, the holes on the side of the gas meter box for installing pipes are relatively large, resulting in gaps between the gas meter box and the pipes. Moisture and dust can easily enter the gas meter box, posing a risk of corrosion to the gas meter or pipes inside. Utility Model Content

[0004] The technical problem this utility model aims to solve is that the holes on the side of the gas metering box used for installing pipes are too large during use, resulting in gaps between the gas metering box and the pipes. This allows moisture and dust to easily enter the gas metering box, posing a risk of corrosion to the gas meter or pipes inside.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A gas metering box includes a metering box body, with through pipe holes on both sides of the metering box body. Sealing sleeves are provided on the inner and outer sides of the through pipe holes. The sealing sleeves are fixedly connected to the metering box body by adhesive. The end of the sealing sleeve away from the metering box body is inclined inward, and the edge of this end of the sealing sleeve is turned outward at a 45-degree angle. A restraining ring is fitted on the outer side of this end of the sealing sleeve.

[0007] Preferably, the minimum inner diameter of the sealing sleeve is smaller than the outer diameter of the gas pipe, and the inner diameter of the perforation in the pipe is larger than the outer diameter of the pipe.

[0008] Preferably, a protective panel is detachably mounted on the front surface of the metering box, and a rotating panel is rotatably mounted on the bottom of the protective panel.

[0009] Preferably, the front surfaces of both the protective panel and the rotating panel are inlaid with multiple observation windows, and the observation windows are made of tempered glass.

[0010] Preferably, the restraint ring includes a rubber protective ring made of rubber, and multiple connecting arc-shaped blocks are installed on the inner side of the rubber protective ring, the connecting arc-shaped blocks being arranged in a circular array around the center of the rubber protective ring.

[0011] Preferably, an elastic connecting rope is fixed between every two adjacent connecting arc blocks, and the elastic connecting rope is made of rubber.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] By using a sealing sleeve to fit against the outer surface of the gas pipe installed through the pipe perforation, the gap between the gas pipe and the pipe perforation is sealed, thereby preventing external dust and moisture from entering the metering box and ensuring that the pipe and gas meter installed inside the metering box are not corroded by dust and external moisture.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1As shown, a gas metering box includes a metering box body 1. A protective panel 2 is detachably installed on the front surface of the metering box body 1. A rotating panel 3 is rotatably installed on the bottom of the protective panel 2. Multiple observation windows 4 are embedded on the front surfaces of both the protective panel 2 and the rotating panel 3. The observation windows 4 are made of tempered glass. The presence of the observation windows 4 facilitates the staff to read the gas meter inside the metering box body 1 or observe its operation.

[0021] As a preferred technical solution in this embodiment, such as Figures 1 to 3 As shown, both sides of the metering box body 1 are provided with through pipe holes 6. Sealing sleeves 5 are provided on the inner and outer sides of the pipe holes 6. The sealing sleeves 5 are fixedly connected to the metering box body 1 by adhesive. The end of the sealing sleeve 5 away from the metering box body 1 is inclined inward, and the edge of this end of the sealing sleeve 5 is turned outward at a 45-degree angle. A binding ring 7 is fitted on the outer side of this end of the sealing sleeve 5. The sealing sleeve 5 is used to fit against the outer surface of the gas pipe installed through the pipe holes 6, thereby sealing the gap between the gas pipe and the pipe holes 6, thus preventing external dust and moisture from entering the interior of the metering box body 1.

[0022] The minimum inner diameter of the sealing sleeve 5 is smaller than the outer diameter of the gas pipe, and the inner diameter of the pipe perforation 6 is larger than the outer diameter of the pipe, ensuring that the pipe can be installed smoothly and that the sealing sleeve 5 can fit tightly against the outer surface of the pipe.

[0023] As a preferred technical solution in this embodiment, such as Figure 4 As shown, the restraint ring 7 includes a rubber protective ring 71, which is made of rubber. Multiple connecting arc blocks 72 are installed on the inner side of the rubber protective ring 71. The connecting arc blocks 72 are arranged in a circular array around the center of the rubber protective ring 71. An elastic connecting rope 73 is fixed between every two adjacent connecting arc blocks 72. The elastic connecting rope 73 is made of rubber band. The spacing between the connecting arc blocks 72 is adjusted by the elastic connecting rope 73, while the connecting arc blocks 72 increase the strength of the rubber protective ring 71, thereby ensuring that the end of the sealing sleeve 5 fits against the outer surface of the gas pipe and achieves a seal.

[0024] Working Principle: When using the gas metering box, first select a suitable location to install and fix the metering box body 1. Then, install the protective panel 2, and install the gas meter, meter, sensor, and other devices inside the metering box body 1. Next, pass the gas pipe through the pipe through hole 6 on the side of the metering box body 1 and extend it into the inside of the metering box body 1. Connect the gas pipe to the gas meter, meter, sensor, and other devices. When installing the gas pipe, expand the ends of the rubber protective ring 71 and the sealing sleeve 5, increase the spacing between the curved connecting blocks 72, and make the elastic connection... The connecting rope 73 is stretched, and at the same time the inner diameter of the sealing sleeve 5 expands. After the gas pipe passes through the sealing sleeve 5 and the pipe perforation 6, the rubber protective ring 71 is released. The elastic connecting rope 73 elastically recovers and drives the connecting arc block 72 and the rubber protective ring 71 to recover, so that the rubber protective ring 71 presses the sealing sleeve 5 tightly against the outer surface of the gas pipe, thereby sealing the gap between the gas pipe and the pipe perforation 6, thus preventing external dust and moisture from entering the metering box 1, and ensuring that the pipes and gas meter installed inside the metering box 1 will not be corroded by dust and external moisture.

[0025] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
