[0002] A pressure reducing valve is a valve that reduces the inlet pressure to a required outlet pressure through adjustment and relies on the energy of the medium itself to automatically maintain the outlet pressure stable. From the perspective of fluid mechanics, a pressure reducing valve is a throttling element with variable local resistance, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of pressure reduction.

[0003] According to the patent document: CN221097679U, there is disclosed an industrial pipeline gas pressure reducing valve, which relates to the technical field of gas pressure reducing valves, including a valve body. A first trapezoidal hole is opened inside the valve body, a valve seat is arranged inside the first trapezoidal hole, a valve cover is fixed on the top of the valve body, a gasket is arranged inside the valve cover, a second trapezoidal hole is opened on the top of the valve body and inside the valve cover, a trapezoidal block is arranged inside the second trapezoidal hole, a spring is fixed between the gasket and the trapezoidal block, and a connecting rod is fixed between the valve seat and the trapezoidal block. In the utility model, gas is filled into the square cavity through the first hose and the second hose. When the pressure sensor senses the pressure inside the square cavity, when the pressure is too high, the alarm will sound at this time, which can play the role of reminding personnel that the pressure inside the valve body is too high, so as to enable personnel to adjust the pressure in the first time, and further achieve the effect of protecting the valve body and the pipeline.

When encountering rain, snow or other weather in winter, they are prone to freezing and cracking, resulting in damage to the pressure reducing valves. Moreover, when damaged, the pressure reducing valves are prone to perform pressure relief work before reaching the pressure relief value, which cannot meet the usage requirements.

While pumping air, the solenoid valve 207 is opened, and then the gas is pumped in. After heating, it is sprayed out through the corrugated pipe 205 and the spray head 204. At the same time, the motor 201 will drive the lead screw 202 to rotate, the lead screw 202 drives the threaded sleeve 203 to move, the threaded sleeve 203 drives the spray head 204 to move, so that the spray head 204 moves to the top of the valve body 301, and at the same time drives the sliding sleeve to move, thereby making the vertical plate 208 move, that is, the roller 211 can be made to move. As the roller 211 moves, the fixing plate 214 will descend, the fixing plate 214 drives the bottom plate 213 to move, so that the bottom plate 213 is separated from the housing 1, facilitating gas discharge, thereby adjusting the temperature value in the inner cavity of the housing 1 and preventing the valve body 301 from cracking; One side of the hot air blower 206 is communicated with a solenoid valve 207, and the surface of the solenoid valve 207 is fixedly connected to the housing 1.

By setting the fixed seat, the operation of the valve body 301 is stabilized and the valve body 301 is limited.

[0024] Working principle: By setting the anti-freezing mechanism 2, the temperature value is set through an external PLC controller. After the temperature sensor 215 detects that the temperature value is lower than the set value, the processor 305 will control the hot air blower 206 and the motor 201 to work. While pumping air, the solenoid valve 207 is opened, and then the gas is pumped in. After heating, it is sprayed out through the corrugated pipe 205 and the nozzle 204. At the same time, the motor 201 will drive the lead screw 202 to rotate. The lead screw 202 drives the threaded sleeve 203 to move. The threaded sleeve 203 drives the nozzle 204 to move, so that the nozzle 204 moves to the top of the valve body 301. At the same time, it will drive the sliding sleeve to move, so that the vertical plate 208 moves, and then the roller 211 can move. As the roller 211 moves, the fixing plate 214 will descend. The fixing plate 214 drives the bottom plate 213 to move, so that the bottom plate 213 is separated from the housing 1, facilitating the discharge of gas, and thus the temperature value in the inner cavity of the housing 1 can be adjusted to prevent the valve body 301 from cracking.
