Abstract
The utility model relates to a connection pipe for gas and natural gas meters, which relates to a connection pipe between gas and natural gas meters and pipelines, and the utility model is used for solving the problems of gas poisoning and exploding body injury accidents caused by welding seams, short service life of the connection pipe caused by easy corrosion and other problems in the prior art. The utility model is composed of nuts, joints and corrugated pipes, wherein, both ends of the corrugated pipe and the two joints are integrally formed, the connection point of the corrugated pipe and the joint is provided without welding seams, and the two joints are respectively connected with the two nuts. The utility model has the advantages of safe use, hard to being rusted, simple process and low cost, and the utility model is mainly used for the field of gas and natural gas meter installation.
Description
Technical field
The utility model relates to a kind of connecting tube, and especially a kind of coal gas, natural gas meter tool of being used for is to the connecting tube between the pipeline.
Background technique
Existing coal gas, natural gas meter tool to the connecting tube between the pipeline are formed (see figure 1) by nut 1 ', joint 2 ', bellows 3 ' institute, wherein the two ends of bellows 3 ' are connected with welding method with two joints 2 ', and two joints 2 ' are connected with two nuts 1 ' respectively.Owing between bellows 3 ' and joint 2 ', there is a tiny weld seam 4 ', just easily produce coal gas or natural gas leaking, cause the personal injury accident of gas poisoning and blast, simultaneously because the existence of weld seam, easily produce corrosion in the weld joint, cause connecting tube shortening in working life.
Summary of the invention
The purpose of this utility model provides a kind of coal gas, natural gas meter tool connecting tube, in order to solve prior art because weld seam causes the personal injury accident of gas poisoning and blast, the perishable problem such as connecting tube shortening in working life that causes.
The purpose of this utility model is achieved in that the utility model is made up of nut, joint, bellows, and wherein the two ends of bellows and two joints are one-body molded, and bellows and joint joint do not have weld seam, and two joints are connected with two nuts respectively.Owing between bellows and joint, there is not a tiny weld seam, so just can thoroughly solve because weld seam causes the perishable problem such as connecting tube shortening in working life that causes in the leakage of coal gas or rock gas and weld joint.
Compared with prior art, the utility model has following advantage:
1. safe in utilization, minimizing personal injury accident;
2. be difficult for burn into and prolong connecting tube working life;
3. save the twice welding procedure, reduce production costs, improve labor productivity.
Description of drawings
Fig. 1 is existing coal gas, natural gas meter tool connecting tube structural representation;
Fig. 2 is the utility model structural representation.
Symbol and element are to as directed among the figure:
1 ', 1 nut
2 ', 2 joints
3 ', 3 bellowss
4 ' weld seam
Embodiment
With reference to accompanying drawing, in conjunction with the embodiments, the utility model is described in further detail.As shown in Figure 2, the utility model is made up of nut 1, joint 2, bellows 3, and wherein the two ends of bellows 3 and two joints 2 are one-body molded, and joint 2 and bellows 3 joints do not have weld seam, and two joints 2 are connected with two nuts 1 respectively.Two nuts 1 socket-connect with coal gas, natural gas meter tool and pipeline respectively, and the connecting tube intermediate portion is a bellows 3, and it can be by crooked direction and the length adjusted, and the socket of nut and coal gas, natural gas meter tool and pipeline are sealed more and firmly.Owing between bellows 3 and joint 2, eliminated a tiny weld seam, thereby stopped the perishable problem such as connecting tube shortening in working life that causes in the leakage of the coal gas that causes owing to weld seam or rock gas and weld joint.Owing in the production process of product, save the twice welding procedure, reduced cost of production, save the operating time, thereby improved labor productivity.China region is vast, and coal gas, natural gas resource enrich, and the market potential of the utility model product can not be underestimated.
