Problems solved by technology

However, in fact, the above-mentioned control process is relatively long, mainly because the elastic force of the spring is not a constant force. Therefore, because the elastic force of the spring cannot fully guarantee the constant force state during use, the decompression process is relatively time-consuming. In addition, the control of the decompression amount from the high-pressure pipeline to the low-pressure pipeline in the above process is actually done by The downward spring force of spring b2 and the gas pressure are jointly determined, and neither force can be too large. This actually requires extremely high standards for the formulation of spring b2. In fact, it is difficult to achieve accurate preparation of spring b2 in traditional production, that is, It is difficult to precisely control the decompression from the high-pressure pipeline to the low-pressure pipeline. In order to improve the control of the decompression from the high-pressure pipeline to the low-pressure pipeline, in the traditional technology, it is necessary to improve and explore step by step through a large number of use or experimental data statistics. In fact, it is also because The elastic force of the spring is not a single constant force in use. Its own force changes are complex and difficult to model. It is also difficult to achieve precise theoretical control in the research on its use. In use, users often rely on high-pressure pipelines and low-pressure pipelines. The actual pressure count value to determine the amount of decompression from the high pressure pipe to the low pressure pipe, and then adjust the spring compression degree (actually adjust the spring force when the spring is balanced with the gas pressure), until the decompression amount from the high pressure pipe to the low pressure pipe is satisfactory The numerical value may be within a satisfactory numerical range. Here we can find that in fact, this kind of operation process is relatively complicated. Even some manufacturers may use a large amount of statistical data as a basis to mark the corresponding scale line in production. Regulation provides a reference, however, in the process of actual use, the stiffness coefficient of the spring will also change significantly due to the use time, and the spring and the pipe wall b1 in contact with each other will change due to the generation of metal oxides or corrosion over time Friction makes the decompression control very imprecise, and the control process is also very inefficient

Description

technical field [0001] The invention relates to a gas decompression device, in particular to a high-efficiency gas decompression device. Background technique [0002] Conventional gas pressure reducing device technologies such as figure 1 The illustrated gas decompression device includes a high-pressure gas pipeline b7 and a low-pressure pipeline b8, and a decompression device is set between the high-pressure pipeline b7 and the low-pressure pipeline b8. The main principle is that when the gas pressure in the pipeline changes For example, the gas pressure in the high-pressure pipeline b7 suddenly increases, and the high pressure of the gas is transmitted to the damping hole b9 through the flow of the gas. The damping hole b9 is only set on the side of the low-pressure pipeline b8, and the increased high pressure directly leads to the upper side of the damping hole b9. The gas in the cavity squeezes the diaphragm b4, and after the diaphragm b4 is squeezed (the gas pressure i...
