DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 , the utility model provides a technical solution:

[0026] Embodiment 1:

[0027] A thermostatic bimetallic steam trap comprises a trap body 1, a shell 2 is arranged on the surface of the trap body 1, connection plates 3 are installed at both ends of the shell 2, inlet and outlet pipes 4 are connected at both ends of the trap body 1, and a replacement component is installed on the surface of the shell 2;

[0028] The replacement assembly includes a replacement plate 5, an articulated seat 6, a slider 7, a bidirectional screw rod 8, and a connecting rod 9. The surfaces of the two connecting plates 3 are symmetrically mounted with the replacement plates 5. The slider 7 is slidably connected in the through groove opened on the surface of the replacement plate 5. The bidirectional screw rod 8 is threadedly connected in the threaded hole opened on the surface of the slider 7. Both ends of the bidirectional screw rod 8 penetrate the slider 7 and are rotatably connected to the inside of the replacement plate 5. The bottom surface of the slider 7 is hinged with a connecting rod 9. The surface of the housing 2 is symmetrically mounted with an articulated seat 6. One end of the connecting rod 9 is hinged to the articulated seat 6. One end of the bidirectional screw rod 8 penetrates the replacement plate 5 and extends to the outside of the replacement plate 5 and is connected to a handle 17 arranged on the outside of the replacement plate 5, so that the housing 2 can be separated, which is convenient for repairing the components of the steam trap body 1, and further improves the work efficiency of repairing the steam trap body 1.

[0029] A guide rod 10 is slidably connected in the through hole opened on the surface of the slider 7. Both ends of the guide rod 10 pass through the slider 7 and are installed inside the replacement plate 5, so as to improve the stability of the shell 2 during separation and avoid position displacement of the slider 7 during the separation process.

[0030] A stabilizing plate 11 is symmetrically mounted on the surface of the replacement plate 5. The stabilizing plate 11 is slidably connected to a moving groove provided on the surface of the connection plate 3. The stabilizing plate 11 can stabilize the housing 2 during its up and down movement.

[0031] The limiting rod 12 is slidably connected in the through hole opened on the surface of the stabilizing plate 11. Both ends of the limiting rod 12 penetrate the stabilizing plate 11 and are installed in the moving groove opened on the surface of the connecting plate 3. The limiting rod 12 can guide the moving position of the stabilizing plate 11 to prevent the stabilizing plate 11 from shifting during the movement.

[0032] Embodiment 2:

[0033] Although the above technical solution facilitates the maintenance and replacement of the components inside the steam trap body 1 by replacing the components, leakage is prone to occur during the normal use of the shell 2. Therefore, in this embodiment, a sealing strip 13 is provided on the surface of the shell 2, and a mounting block 14 is symmetrically installed on the surface of the sealing strip 13. A sliding groove matching the mounting block 14 is provided on the surface of the connecting plate 3. The sealing strip 13 and the connecting plate 3 are slidably connected through the mounting block 14 and the sliding groove. A threaded sleeve 15 is installed on the surface of the sealing strip 13. A bolt 16 is threadedly connected in the threaded hole provided on the surface of the shell 2. One end of the bolt 16 passes through the shell 2 and is threadedly connected to the inside of the threaded sleeve 15, thereby avoiding leakage at the connection between the two shells 2 during normal use.

[0034] Working principle: First, the bidirectional screw rod 8 is rotated by the handle 17. At this time, the bidirectional screw rod 8 drives the slider 7 to slide inside the replacement plate 5. The slider 7 slides on the surface of the guide rod 10 during the sliding process. The guide rod 10 can prevent the slider 7 from shifting in position during the movement. The slider 7 drives the connecting rod 9 to move in the hinge seat 6 during the sliding process, thereby driving the outer shell 2 to move, so that the two outer shells 2 are separated. When the outer shell 2 moves, it drives the stabilizing plate 11 to slide on the surface of the limit rod 12 in the moving groove on the surface of the connecting plate 3. The limit rod 12 and the stabilizing plate 11 can stabilize the position of the outer shell 2 during the up and down movement, avoiding position shift during the movement, thereby repairing and replacing the components in the internal steam trap body 1.

[0035] When the two shells 2 are combined and used normally, the two sealing strips 13 are fitted together, and the sealing strip 13 seals the connection between the two shells 2 to avoid leakage from the connection between the two shells 2 during use. When the sealing strip 13 is old, the bolt 16 is rotated to disengage from the inside of the threaded sleeve 15. At this time, the sealing strip 13 is pulled, and the mounting block 14 on the sealing strip 13 is disengaged from the slide groove opened on the surface of the connecting plate 3, so that the sealing strip 13 is replaced.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
