Description

Technical Field

[0001] The utility model relates to the technical field of gas valves, in particular to a cut-off valve for town gas. Background Art

[0002] After a substantial increase in the supply of artificial gas in 1990, it is now in a relatively slow growth stage due to its disadvantages such as greater pollution and toxicity. LPG is affected by the rise in oil prices, and its supply remains stable. The price of natural gas with the same calorific value is 30%-50% cheaper than gasoline and diesel, which is obviously economical. At the same time, the country is paying more and more attention to environmental protection, and the market demand for clean energy continues to grow. As a clean, efficient and cheap energy source, natural gas consumption has developed rapidly, so the existing gas technology has been continuously innovated and developed. The gas valve is a new type of safety supporting device for gas pipeline projects, which is used to cut off, connect and adjust the gas in the pipeline. It has good control characteristics and closing and sealing performance; it is suitable for city gas, liquefied petroleum gas, natural gas, oxygen and other gas medium pipelines. Therefore, the current gas valve device basically meets people's needs, but there are still some problems.

[0003] During the installation of gas valves, flange connections are usually used between valves and pipelines. Although this connection method is strong, it is cumbersome and time-consuming to install and disassemble. In addition, during installation and use, the heavy valve needs to rely on the pipeline support, which is not flexible to install and can easily bend the pipeline. Therefore, a shut-off valve for urban gas is urgently needed to solve the above problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. A shut-off valve for town gas is provided with a quick-connect component group. During the installation of the gas valve, the valve and the pipeline are usually connected by flange type. Although this connection method is strong, it is relatively cumbersome and the installation and disassembly wastes time. In the corresponding design 02, before installing the valve, the upper connector and the lower connector are first fitted to the connection port of the valve body, and the upper connector and the lower connector are firmly connected by the first bolt and the first nut. At this time, due to the presence of the sliding groove and the limit ring, the upper connector and the lower connector can be limited horizontally moved on the valve body. At this time, the overall valve is installed, and the external gas pipeline and the valve body interface are directly aligned. The upper connector and the lower connector are connected together by threads, and after the upper connector and the lower connector are rotated several times, the valve body and the gas pipeline will be tightly connected together, and the internal gas will not leak out. When the shut-off valve needs to be uninstalled, it can be quickly uninstalled by simply unscrewing the upper connector and the lower connector. The design of this quick-connect component group greatly reduces the installation and uninstallation time between the valve and the pipeline, and increases work efficiency;

[0013] 2. This kind of shut-off valve for urban gas is provided with a valve support component group. During installation and use, the heavy valve needs to rely on the pipeline support. The installation is not flexible and it is easy to bend the pipeline, which is very likely to cause safety hazards. Therefore, the valve support component group is designed. Before installation, the connecting ring is first sleeved on the outer wall of the valve body, and then the adjusting rod is inserted into the corresponding slide groove. Then, according to the different external support structures, it is adjusted to the corresponding through groove position, and then the connection and fixation are completed through the second nut and the bottom plate. At this time, the shut-off valve device does not need to rely on the support of the external connecting pipeline. The adjustable design can achieve corresponding adjustment according to the different external support terrain, thereby increasing the use surface of the device. At the same time, during the installation process, the valve is auxiliary supported, which can be convenient for installation, thereby improving the installation efficiency.

The adjustable design can achieve corresponding adjustments according to the different external support terrain, thereby increasing the use surface of the device. At the same time, during the installation process, the valve is auxiliary supported, which can facilitate installation and improve the installation efficiency.
