The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0033] like Figure 1-2 As shown, a steam heating device in one embodiment of the utility model includes an insulation box 12, a first through pipe 15 and a plurality of steam separation valves 20; the insulation box 12 is provided with a door leaf 13 for controlling the opening and closing state of the insulation box 12, and the door leaf 13 is provided with a door lock 14 for controlling the locking and opening state of the door leaf 13 and the insulation box 12; the first through pipe 15 runs through the insulation box 12; the plurality of steam separation valves 20 are sequentially arranged on the first through pipe 15, and the plurality of steam separation valves 20 are all arranged in the insulation box 12.

[0034] The steam tracing device, by locating multiple steam separation valves 20 within the insulation box 12, facilitates unified management, prevents misoperation, and prevents significant heat loss from the steam. The multiple steam separation valves 20 facilitate steam delivery to the corresponding workstations as needed. This steam tracing device solves the problem of traditional valve groups being easily frozen in winter and requiring insulation.

[0035] like Figure 3-6 As shown, in one embodiment, the steam separation valve 20 includes a valve body 1 and multiple valves; a main channel 11 and multiple first channels 5 connected to the main channel 11 are provided in the valve body 1, a first partition 4 is provided in the first channel 5, and a through hole 6 connected to the first channel 5 is provided on the first partition 4; the valve includes a sleeve 2 and a rotating component 3; one sleeve 2 is inserted on the valve body 1 and connected to one first channel 5; the rotating component 3 is inserted in the sleeve 2 and threadedly connected to the sleeve 2, the rotating component 3 abuts against the first partition 4, and the rotating component 3 is used to control the connectivity state of the through hole 6; the main channel 11 is connected to the first through pipe 15. In this way, by rotating and controlling the rotating component 3 corresponding to the first channel 5, the abutment state of the rotating component 3 and the first partition 4 is controlled, so that the gas in the main channel 11 is diverted to the corresponding first channel 5; when the rotating component 3 abuts the first partition 4, the through hole 6 is in a closed state, so that the first channel 5 is closed; when the rotating component 3 is separated from the first partition 4, the through hole 6 is in a connected state, so that the first channel 5 is opened.

[0036] like Figure 4 As shown, in one embodiment, the first channel 5 includes a first flow channel 51 , a second flow channel 52 and a third flow channel 53 that are connected in sequence; the first partition layer 4 is disposed in the third flow channel 53 .

[0037] like Figure 3-6As shown in one embodiment, the rotating assembly 3 includes a connecting rod 31, a sealing piece and a bellows 32. The connecting rod 31 is inserted into the sleeve 2 and is threadedly connected to the sleeve 2. One end of the connecting rod 31 is connected to the sealing piece. A sealing ring 7 is also provided in the sleeve 2. The sealing ring 7 is connected to the inner wall of the sleeve 2, and the connecting rod 31 passes through the sealing ring 7. The bellows 32 is provided in the sleeve 2 and is sleeved on the sleeve 2. On the connecting rod 31, one end of the bellows 32 is connected to the sealing ring 7, and the other end of the bellows 32 is connected to the sealing member. The sealing member includes a base 33 and an abutting block 34 with a spherical outer contour. The cross section of the base 33 is H-shaped. The abutting block 34 is provided on one end of the base 33, and the other end of the base 33 is provided with a flange. One end of the connecting rod 31 is engaged with the flange, and the bellows 32 is connected to the base 33. In this way, the abutting state of the abutting block 34 and the through hole 6 is controlled by rotating the connecting rod 31, thereby controlling the connectivity of the first channel 5. When the connecting rod 31 moves, the bellows 32 prevents gas from leaking from the gap between the sealing ring 7 and the connecting rod 31. The flange is engaged with the connecting rod 31, and when the connecting rod 31 rotates, the sealing member and the bellows 32 are prevented from rotating with the connecting rod 31, thereby affecting the airtightness of the valve.

[0038] like Figure 6-7 As shown, in one embodiment, the sleeve 2 is provided with a second barrier layer 8, through which the connecting rod 31 passes. A sealing block 10 is sleeved over the connecting rod 31, abutting the second barrier layer 8. A handle 9 is provided on the end of the connecting rod 31 away from the blocking member. Thus, when the through hole 6 is connected, the sealing block 10 abuts the second barrier layer 8, achieving a secondary seal and improving the sealing performance of the valve.

[0040] In one embodiment, the heat preservation box 12 and the door leaf 13 are both made of stainless steel plates, and the thickness of the stainless steel plates is equal to or greater than 1.5 mm.

[0041] In one embodiment, the thermal insulation box 12 is further provided with an aerogel nano-ceramic powder spray layer and an aluminum silicate fiber cotton insulation layer.

[0042] In one embodiment, the door lock is of a one-key multi-lock type, which is convenient for full-time personnel to operate and manage.

[0043] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments merely represent several implementations of the present invention.
