Gas valve comprehensive detection platform

Abstract

The invention provides a comprehensive detection platform for gas valves. The comprehensive detection platform ingeniously integrates all grades of gas pipelines with different flow capacities, different connectors and different pressure regulation capabilities in a gas pipe network in China at present, so the comprehensive performance of the gas valves with different models can be effectively detected. The comprehensive detection platform comprises an upstream pipeline, an upstream flow distribution mechanism, a downstream pipeline, a downstream flow distribution mechanism, a hydraulic cylinder, a measured valve body and a moving mechanism, wherein the upstream pipeline and the upstream flow distribution mechanism are used for simulating a main gas pipeline or branch main pipelines in the gas pipe network; the downstream pipeline and the downstream flow distribution mechanism are used for simulating a user pipeline or branch pipelines in the gas pipe network; the hydraulic cylinder is arranged at the top end of the upstream pipeline, pushes the upstream flow distribution mechanism through motion of a piston rod and enables the upstream flow distribution mechanism to be in butt joint with the measured valve body; the measured valve body is mounted on the moving mechanism through bolts, and the two end faces of the measured valve body can be matched with the upstream flow distribution mechanism and the downstream flow distribution mechanism; the moving mechanism provides a mounting platform for measured valve bodies with different models, and delivers the measured valve bodies to a testing position. By the adoption of the comprehensive detection platform, system sensitive parameters can be observed, measured, controlled and adjusted; the comprehensive detection platform is convenient and fast to use and high in universality.

Description

technical field [0001] The invention relates to a gas valve comprehensive detection platform. Background technique [0002] With the continuous development of urban construction, the coverage area of ​​the gas pipeline network is getting higher and higher. In the gas supply system, the gas valve is used to adjust the pressure of the medium and high pressure pipeline network of pipeline gas to enter the low-voltage users. For example, the pressure of the pipeline gas network is usually medium pressure (0.2-0.4MPa), high pressure (2.5-4MPa) or sub-high pressure (0.8-1.6Mpa). In the pipeline gas pipeline network, the gas valve realizes the pressure regulation between the gas main pipeline and the branch main pipeline, and between the branch main pipeline and the user. Some gas pipelines need to go through two or even three levels of pressure regulation before they can enter the user pipeline for use. . Due to the difference in pressure regulation and flow capacity at all leve...

Problems solved by technology

Because different types of gas valves have different flow diameters and pressure regulating capabilities, and there is no universal gas valve testing equipment on the market and in various production units, so the detection of different types of gas valves needs to be performed in different testing systems. Each type of gas valve requires a set of gas valve detection equipment corresponding to its flow capacity, interface and pressure regulation capacity. If a new type of gas valve is added, a new set of gas valves needs to be redesigned and processed. The matching detection equipment greatly increases the detection cost, and brings great inconvenience to production and processing, resulting in waste of resources and labor
