Prefabricated clamping and pressing connecting assembly of assembly type gas meter box

Abstract

The invention relates to an assembly type gas meter box prefabricated clamping and pressing connection assembly which comprises two meter boxes to twelve meter boxes. The prefabricated clamping and pressing connecting assembly matched with the gas meter box body is composed of a gas main pipeline, a first gas branch pipeline, a second gas branch pipeline, a third gas branch pipeline, a fourth gas branch pipeline, a fifth gas branch pipeline, a sixth gas branch pipeline, a pipeline fixing device and a gas meter. According to the fabricated gas meter box, a left-in-left-out structure, a left-in-right-out structure, a right-in-left-out structure or a right-in-right-out structure is customized according to clients, the construction efficiency is improved, the installation difficulty is reduced, the gas main pipeline, the gas flow dividing pipe assembly and the loose joint type flow stabilizing pipeline are all prefabricated parts, factory assembly line work is achieved, compared with the prior art, the working efficiency is improved by more than 50%, and the cost is reduced. The production cost is reduced by more than 35%, on-site welding and wire twisting are not needed, connection nodes and leakage points are reduced, the leakage problem of the joint in the gas meter is effectively controlled, the market prospect is wide, and the economic benefit is remarkable.

Description

technical field [0001] The invention belongs to the technical field of gas meter box pipeline accessories, in particular to a prefabricated clamping connection assembly of an assembled gas meter box. Background technique [0002] Most of the existing gas meter boxes are equipped with a single gas meter. The connection between the inlet and outlet pipes is mainly threaded. Passage, pipeline flange, etc., complex structure, many interfaces, difficult installation, frequent gas leakage. With the development of society, there are more and more high-rise buildings, which put forward new requirements for the gas preparation of high-rise buildings. Gas is a commodity that is necessary for flammable and explosive life. It has a high penetration rate and is related to thousands of households. As large as the city, there are gas companies at all levels for unified management. Even if there is only one gas company, a gas meter box of a uniform size must be installed. In addition to pr...

Problems solved by technology

At present, the structure of the gas meter box is unreasonable, and it is impossible to provide the corresponding gas meter box and pipeline accessories according to the actual needs of residents' gas meter assembly, which leads to the fundamental reason that users and gas companies are uneconomical.

At present, the gas meter boxes used by urban residents are all provided by the gas company. The existing gas meter boxes are all metal boxes with uniform size for the same building, and their external dimensions are determined according to the floors of the buildings. Install two gas meter boxes in each corridor, and install the same number of gas meters in each gas meter box as the number of floors. For buildings with different floors, the dimensions and specifications of the gas meter boxes used in each building are different, and the pipeline accessories On-site production is not only labor-intensive, safety cannot be guaranteed, but also a great waste of raw materials
