[0025] In some embodiments, the upper shell 1 and the lower shell 2 are respectively provided with outer edges 5 on both sides, and the outer edges 5 are attached to each other when the upper shell 1 and the lower shell 2 are molded together. The outer edges 5 of the upper shell 1 and the lower shell 2 are respectively provided with screw holes, and bolts 6 are respectively provided in the screw holes, and the bolts 6 are respectively screwed into the corresponding screw holes. Figure 1-4 As shown, outer edges 5 are respectively provided on both sides of the upper shell 1 and the lower shell 2. The outer edges 5 increase the contact between the upper shell 1 and the lower shell 2. At the same time, the screw holes provided on them allow the upper shell 1 and the lower shell 2 to be quickly disassembled and assembled using bolts 6.

[0026] In some embodiments, the first sealing mechanism includes: a sealing groove 7, a plurality of sealing grooves 7 are provided on the side of the lower shell 2 close to the upper shell 1, and a sealing strip 8 adapted to the sealing groove 7 is provided on the side of the upper shell 1 close to the lower shell 2. The upper shell 1 and the lower shell 2 are respectively connected by the sealing groove 7 and the sealing strip 8. Figure 1-4 As shown, the sealing groove 7 and the sealing strip 8 increase the guiding role in the facing fit between the lower shell 2 and the upper shell 1. At the same time, in the connection between the upper shell 1 and the lower shell 2, it can increase the sealing effect. The sealing strip 8 can be a rubber strip. The length of the sealing strip 8 and the sealing groove 7 can be along the edge of the upper shell 1 and the lower shell 2, and it is arranged to avoid the main line port 3 and the branch line port 4.
