[0002] A valve is a device installed on a pipeline for controlling fluids, such as the direction, pressure, and flow rate of liquids and gases. A valve is a key control component in a fluid transportation system and has multiple functions, including cut-off, regulation, diversion, prevention of backflow, pressure stabilization, flow splitting, or overflow pressure relief, etc.

[0003] Existing electronically controlled valves can give a high-pressure alarm according to a preset pressure threshold. However, many pipeline valves are installed outdoors, and the electronic control components and alarm mechanisms are exposed without a shielding mechanism, making them easily damaged. At the same time, some electronically controlled valves are installed on pipelines with a large span, lacking a support mechanism at the bottom, and the joints are prone to deformation due to gravity after long-term use. Therefore, it is necessary to design a valve with a high-pressure alarm function for the above problems. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: A valve with a high-pressure alarm function, including a valve body 1, a pressure gauge 2, an acousto-optic alarm 3, a side bolt 4, a side nut 5, a limit window 6, a support plate 7, a shielding cover 8, a positioning plate 9, a track window 10, a positioning bolt 11, a positioning nut 12, a vertical plate 13, a support rod 14, a substrate 15 and an anchor pin 16. A pressure gauge 2 and an acousto-optic alarm 3 are arranged on the top of the valve body 1. The pressure gauge 2 is electrically connected to the acousto-optic alarm 3. A side bolt 4 is fixedly installed on the side of the top of the valve body 1. A side nut 5 is installed at the end of the side bolt 4. The side bolt 4 passes through the limit window 6. The limit window 6 is opened at the bottom of the support plate 7. The side bolt 4 is slidably connected to the limit window 6. The limit windows 6 are symmetrically distributed about the center of the support plate 7. The length of the limit window 6 is greater than 1 / 3 of the overall height of the support plate 7. The above structural design enables the support plate 7 to drive the limit window 6 to perform a vertical adjustment with a sufficient distance from the side bolt 4, and conveniently adjust the working height of the support plate 7 and the shielding cover 8. A shielding cover 8 is installed at the top of the support plate 7;

[0023] When using this device, first, according to the distance between the valve body 1 and the ground below, pull Figure 4 the vertical plate 13 in

[0024] A positioning plate 9 is fixedly installed at the bottom end of the valve body 1. The width of the positioning plate 9 is greater than half of the diameter of the valve body 1. The overall height of the positioning plate 9 is greater than half of the length of the support rod 14. The above structural design ensures that the spacing between the symmetrically distributed support rods 14 is sufficient, and the support rod 14 can adjust the vertical working position to a sufficient distance. The front view shape of the positioning plate 9 is a "凵" shape. Vertical plates 13 are symmetrically arranged on both sides of the positioning plate 9. Positioning bolts 11 are fixedly installed on the inner side of the vertical plate 13. Positioning nuts 12 are installed at the end of the positioning bolts 11. The inner side of the vertical plate 13 fits the outer side of the positioning plate 9. The positioning bolts 11 pass through the track window 10, and the track window 10 is opened on the side of the positioning plate 9. The above structural design enables the working height of the vertical plate 13 to be conveniently adjusted and stably fixed. The positioning bolts 11 and the track window 10 are slidably connected. The track window 10 is symmetrically distributed about the center of the positioning plate 9. The above structural design enables the vertical plate 13 to slide vertically along the track window 10 with the positioning bolts 11, so as to conveniently adjust the working height.

[0025] Support rods 14 are installed at equal intervals on the outer side of the vertical plate 13. The above structural design makes the overall stability of the support mechanism composed of the positioning plate 9, the vertical plate 13 and the support rod 14 higher and less prone to deformation. The vertical plate 13 is fitted on the outer side of the positioning plate 9, and the outer side of the vertical plate 13 is rotatably connected to the top of the support rod 14. The bottom end of the support rod 14 is rotatably connected to the top surface of one end of the base plate 15. Anchor nails 16 are installed through the middle and the other end of the base plate 15. The anchor nails 16 are arranged at equal intervals. The above structural design ensures that the base plate 15 can be stably connected to the ground, and ensures the supporting effect of the support rod 14 on the valve body 1.

[0026] Then, according to the climatic conditions of the working area, such as light conditions and rainfall, push the support plate 7 with the limit window 6 to slide vertically along the side bolt 4 until the height of the shielding cover 8 is appropriate, rotate the side nut 5 to squeeze the support plate 7 and fix it to the side of the valve body 1, and the support plate 7 and the shielding cover 8 can stably shield and protect the electric control mechanism, pressure gauge 2 and sound and light alarm 3, ensuring that the electric control mechanism, pressure gauge 2 and sound and light alarm 3 can work stably for a long time.
