[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and adjust and control the parameters (temperature, pressure, and flow rate) of the transported medium. According to its functions, it can be divided into shut-off valves, check valves, regulating valves, etc. A valve is a control component in a fluid transportation system, with functions such as cut-off, regulation, diversion, prevention of backflow, pressure stabilization, shunt, or overflow pressure relief. For valves used in fluid control systems, from the simplest cut-off valve to various valves used in extremely complex automatic control systems, their varieties and specifications are quite numerous. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, duplex steel valves, plastic valves, non-standard customized valves, etc.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figure 1-2 , a stainless steel flange valve with an anti-corrosion function in this embodiment, includes a valve body 1, and an adjustment piston mechanism is provided inside and on the top of the valve body 1.
[0021] In this embodiment, the adjustment piston mechanism includes a fixed plate 2 movably connected to the left and right sides of the valve body 1. A branch pipe 3 is fixedly installed inside the fixed plate 2. A fixed bolt 4 threadedly connected to the valve body 1 is threadedly connected inside the fixed plate 2, which is convenient for fixing and disassembling the branch pipe 3 and can transport and circulate water. An adjustment box 5 is fixedly installed on the top of the valve body 1, and an adjustment screw 6 extending to the outside is threadedly connected inside the adjustment box 5.
[0022] Among them, a threaded block 7 is threadedly connected to the outside of the adjustment screw 6. A threaded groove is provided inside the threaded block 7, and the threaded block 7 is threadedly connected to the adjustment screw 6 through the threaded groove, which helps the threaded block 7 to move on the outside of the adjustment screw 6. Limit rods 8 slidably connected to the adjustment box 5 are fixedly installed on the left and right sides of the threaded block 7. Limit grooves are provided on the inner walls of the left and right sides of the adjustment box 5, and the limit rods 8 are slidably connected to the adjustment box 5 through the limit grooves, which helps to limit the limit rods 8.
[0023] In this embodiment, a movable rod 9 extending to the outside of the adjustment box 5 is fixedly installed at the bottom of the threaded block 7. An activity groove is provided at the bottom of the adjustment box 5, and the movable rod 9 is slidably connected to the adjustment box 5 through the activity groove, which helps the movable rod 9 to move. A piston body 10 is fixedly installed on the outside of the movable rod 9, and a knob 11 is fixedly installed on the top of the adjustment screw 6.
[0024] Among them, a limit sleeve 12 that fits with the adjustment box 5 is sleeved on the bottom of the knob 11, which facilitates the limitation of the knob 11 and the adjustment screw rod 6. A waterproof layer 101 is arranged inside the valve body 1, and an anti-corrosion layer 102 is arranged on the other side of the waterproof layer 101. The waterproof layer 101 is a polyurethane waterproof coating, and the anti-corrosion layer 102 is composed of polytetrafluoroethylene PTFE and silicate, which helps to increase the waterproofness and anti-corrosion property of the valve body 1.
[0025] It should be noted that for this stainless steel flange valve with anti-corrosion function, through the set adjustment piston mechanism and the action of the knob 11 and the adjustment screw rod 6, the threaded block 7 can be driven to move up and down, driving the movable rod 9 and the piston body 10 to move up and down. The piston body 10 can be driven to block the pipeline inside the valve body 1, thereby blocking and sealing the valve body 1. When the knob 11 is rotated in the reverse direction, the piston body 10 can be driven to move upward, so that the piston body 10 no longer closes the pipeline inside the valve body 1, and the pipeline inside the valve body 1 can be opened to allow water to flow. With the functions of the waterproof layer 101 and the anti-corrosion layer 102, the waterproof and anti-corrosion functions of the valve body 1 can be enhanced, which helps to increase the service life and safety of the device.
[0026] The working principle of the above embodiment is as follows:
[0027] When using this stainless steel flange valve with anti-corrosion function, first, the knob 11 can be rotated. The knob 11 drives the adjustment screw rod 6 to rotate. The threaded block 7 on the outer side of the adjustment screw rod 6 starts to move under the limitation of the limit rod 8. The threaded block 7 moves on the outer side of the adjustment screw rod 6. The up and down movement of the threaded block 7 drives the movable rod 9 and the piston body 10 to move up and down, so that the movable rod 9 drives the piston body 10 to move up and down. The piston body 10 can be driven to block the pipeline inside the valve body 1, thereby blocking and sealing the valve body 1. When the knob 11 is rotated in the reverse direction, the knob 11 drives the adjustment screw rod 6 to rotate in the reverse direction, and the piston body 10 can be driven to move upward, so that the piston body 10 no longer closes the pipeline inside the valve body 1, and the pipeline inside the valve body 1 can be opened to allow water to flow, which is convenient for quick closing and opening. With the functions of the waterproof layer 101 and the anti-corrosion layer 102, the waterproof and anti-corrosion functions of the valve body 1 can be enhanced, which helps to increase the service life and safety of the device.
