[0002] Magnetic flap level gauges can be used for medium level detection in various towers, tanks, tanks, spherical containers, boilers and other equipment. This series of level gauges can be highly sealed, leak-proof and suitable for high temperature, high pressure and corrosion-resistant occasions. It makes up for the defects of glass plate (tube) level gauges such as poor indication clarity and easy breakage. There is no blind spot in the whole measurement process, with clear display and large measurement range.

[0003] Magnetic flap level gauges are generally installed outside when in use. When the weather temperature is too low, the temperature of the main tube will change with the weather temperature. When the temperature of the medium inside the equipment is higher than the external air temperature, the surface of the scale indicator plate is prone to frost, affecting the viewing effect. Therefore, a magnetic flap level gauge structure that can prevent low-temperature frost is proposed. Utility Model Content

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 The utility model provides a technical solution for the structure of a magnetic flap level gauge that can prevent low-temperature frost, including: a main pipe 1, a first fixed clamp 5, a second fixed clamp 6 and an insulation layer 8. The first fixed clamp 5 is installed near the top position of the main pipe 1, and the second fixed clamp 6 is installed near the bottom position of the main pipe 1. The insulation layer 8 is installed on the second fixed clamp 6. The insulation layer 8 is stacked and sleeved on the outside of the main pipe 1, and the insulation layer 8 can be stacked and stretched and can be wrapped around the outside of the main pipe 1. The insulation layer 8 can use thermal insulation cotton, and a drain valve is installed at the bottom of the main pipe 1.

[0022] like Figure 3 and Figure 4 As shown, an annular groove is provided at the opposite end of the first fixed clamp 5 and the second fixed clamp 6, one end of the thermal insulation layer 8 is installed in the annular groove on the second fixed clamp 6, and a connecting block 10 is symmetrically installed at the other end of the thermal insulation layer 8. A strip rod 9 is installed near the bottom position on one side of the two connecting blocks 10, and a strip frame 7 is symmetrically installed on the back of the scale indicator plate 3. The two strip frames 7 are provided with sliding grooves adapted to the strip rod 9, and the ends of the two strip rods 9 away from the connecting block 10 slide in the strip frame 7, and the strip rods 9 are slidably connected inside the strip frame 7, so that the thermal insulation layer 8 is limited when it moves outside the main tube 1, so that the clamping block 11 is correspondingly inserted into the clamping hole on the first fixed clamp 5.

[0023] like Figure 2 and Figure 5As shown, the two connecting blocks 10 are each provided with an installation groove inside, and a spring 12 is installed in the installation groove. A clamping block 11 is installed at one end of the two springs 12 away from the installation groove.

[0024] The working principle of the utility model is as follows: the connecting pipe 2 is connected and installed with the equipment. When the temperature is too low, the connecting block 10 is pulled upward, the thermal insulation layer 8 moves on the outside of the main pipe 1, and the thermal insulation layer 8 accumulated in the second fixed clamp 6 is pulled out. The two connecting blocks 10 are inserted into the annular groove on the first fixed clamp 5 to squeeze the clamping block 11. The clamping block 11 slides on the connecting block 10, and the clamping block 11 squeezes the spring 12. When the clamping block 11 moves to the clamping hole position on the first fixed clamp 5, the elastic force of the spring 12 makes the clamping block 11 clamped into the clamping hole, the thermal insulation layer 8 is wrapped on the outside of the main pipe 1, and the clamping block 11 is inserted into the first fixed clamp 5 to limit the thermal insulation layer 8.
