The main pipe assembly 100 includes a main valve body 101, a main pipe 102 is arranged in the center of the main valve body 101, and a fixing block 103 is arranged at the lower part of the main valve body 101; the branch pipe assembly 200 includes two sets of first branch valve bodies 201 and a second branch valve body 207 arranged on the upper part of the main valve body 101. A first branch valve passage 202 and a second branch valve passage 208 are respectively arranged inside the first branch valve body 201 and the second branch valve body 207. A first control valve rod 204 and a second control valve rod 210 respectively penetrate through the first branch valve passage 202 and the second branch valve passage 208. The branch pipe assembly 200 further includes an outlet pipe one 205 and an outlet pipe two 211 arranged on both sides of the main valve body 101. Both the first branch valve body 201 and the second branch valve body 207 are located between the outlet pipe one 205 and the outlet pipe two 211 and form an angle of 30 - 60°; the filtering assembly 300 includes a filter pipe 301 arranged on the side of the main valve body 101, and a filter element 302 is arranged inside the filter pipe 301.

[0027] First, in order to ensure that the outlet pipe one 205 and the outlet pipe two 211 can output steam, and the first branch valve passage 202 and the second branch valve passage 208 can respectively control the first air outlet passage 206 and the second air outlet passage 212. Specifically, an first air outlet passage 206 and a second air outlet passage 212 are respectively arranged in the centers of the outlet pipe one 205 and the outlet pipe two 211. The first branch valve passage 202 and the second branch valve passage 208 penetrate through the main pipe 102, and the first air outlet passage 206 and the second air outlet passage 212 respectively penetrate through the first branch valve passage 202 and the second branch valve passage 208.

[0028] Next, in order to ensure that the first control valve rod 204 and the second control valve rod 210 can be opened and closed, and there is no steam leakage when the first control valve rod 204 and the second control valve rod 210 are closed. Specifically, a first valve 203 and a second valve 209 are respectively arranged at the tops of the first control valve rod 204 and the second control valve rod 210, and sealing rings are arranged at the bottoms of the first control valve rod 204 and the second control valve rod 210.

[0029] Secondly, in order to ensure that the filter element 302 can filter, and the filter core 305 can be taken out separately. Specifically, the filter element 302 includes a connecting plate 308, a handle 303 is arranged on the upper part of the connecting plate 308, a filter net 304 is arranged on the lower part of the connecting plate 308, a filter core 305 is arranged inside the filter net 304, two L-shaped grooves are arranged at the center position of the top of the filter core 305, a plurality of filter core switches 307 and a plurality of springs 306 are arranged in the grooves of the filter core 305, the upper part of the filter net 304 is provided with threads for connecting with the filter pipe 301, and sealing rings are arranged at the middle positions of the upper part of the filter net 304 and the filter core 305.

[0030] Working principle: When the device is required to distribute and filter steam, first connect the main pipeline 102 to the main steam tracing pipeline. Then, when the first air outlet 202 needs to be used, rotate the first valve 203 to drive the control valve rod 204 to rise, so that the main pipeline 102 is connected to the first air outlet 206, realizing the steam diversion of the first air outlet 202. Secondly, when the second air outlet 208 needs to be used, rotate the second valve 209 to drive the control valve rod 210 to rise, so that the main pipeline 102 is connected to the second air outlet 212, realizing the steam diversion of the second air outlet 212. While the main steam tracing pipeline inputs steam into the main pipeline 102, the filter element 302 preliminarily filters larger impurities through the filter screen 304, and then secondary filters the steam through the filter core 305 to complete the filtration of the steam. In some cases, the filter core 305 can be taken out and replaced by pinching the filter core switch 307 and lifting the handle 303, or the entire filter element 302 can be taken out for cleaning or replacement by rotating the connecting plate 308.
