[0025] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0026] With reference to Figures 1-5 A steam metering instrument protection device, comprising a flow pipe 1 and an instrument 11 arranged on the flow pipe 1, characterized in that a protective cover 2 is arranged outside the instrument 11, and a support assembly 3 is arranged at the lower end of the protective cover 2 to fix the protective cover 2 on the flow pipe 1.

[0027] An observation window 21 is arranged on the front side of the protective cover 2 corresponding to the instrument 11, and a plurality of heat dissipation holes 22 are arranged on the front and rear sides of the protective cover 2. The observation window 21 can facilitate reading the data on the instrument 11 from the outside, so as to avoid affecting the normal use of the instrument 11. The heat dissipation holes 22 can balance the air pressure inside and outside the protective cover 2, and can be arranged on the upper and lower parts of the protective cover 2 according to the actual installation scene.

[0028] The support assembly 3 comprises a heat insulation seat 31 arranged below the protective cover 2, two supporting legs 33 arranged at the lower end of the heat insulation seat 31, and a pair of half hoops 34 arranged at the lower end of the supporting legs 33. The supporting legs 33 are arranged on both sides of the instrument 11, and the half hoops 34 are provided with heat insulation pads 35 matched with the flow pipe 1. Locking interfaces 341 are arranged on the half hoops 34, and the half hoops 34 can be locked by cooperating with the locking interfaces 341 and the heat insulation pads 35. The heat insulation pads 35 can reduce the heat transfer in the flow pipe 1 and block the heat transfer to the heat insulation seat 31.

[0029] Based on the above technical scheme, the instrument 11 is protected by the protective cover 2 on the outside, and the pressure balance inside and outside the protective cover 2 is ensured by cooperating with the heat dissipation holes 22. The heat transfer from the flow pipe 1 to the protective cover 2 is reduced by cooperating with the design of the heat insulation pads 35 and the heat insulation seat 31, so as to ensure that the temperature in the protective cover 2 is within a suitable range to ensure the stable operation of the instrument 11. By designing the heat insulation pads 35, the corresponding heat insulation pads 35 can be replaced for different diameter flow pipes 1, which can well ensure the compatibility of the protective device.
