DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-4 As shown, the embodiment of the present invention provides a mounting mechanism for a relief valve, comprising:

[0024] The valve body 1 has a connecting pipe 2 at both ends thereof, an outer pipe 3 is provided at the outer end of each of the two connecting pipes 2, and a connecting assembly is provided between each of the two connecting pipes 2 and the outer pipe 3 on the same side;

[0025] The outer side of the sleeve 10 is provided with an internal thread, and the external thread is arranged on the internal thread, so that the sleeve 10 can be screwed onto the annular block 4 through the internal thread and the external thread. Two snap-fit assemblies are provided between the sleeve 10 and the annular block 4.

[0026] The snap assembly includes a movable plate 5, a connecting rod 6, a clamping block 7 and a spring 8. One end of the connecting rod 6 is fixedly arranged on the inner side of the movable plate 5, and the connecting rod 6 slides through the annular block 4. The clamping block 7 is fixedly arranged on the outer side of the movable plate 5. A plurality of clamping holes 12 are provided on the inner bottom of the sleeve 10. The two ends of the spring 8 are respectively fixedly arranged on the inner side of the movable plate 5 and the outer side of the annular block 4.

[0027] Several card holes 12 are evenly distributed around the circumference, and the two card blocks 7 are arranged in conjunction with the several card holes 12, so that the two card blocks 7 can be inserted into the several card holes 12. The outer ends of the two card blocks 7 are arranged with inclined surfaces, so that the card holes 12 squeeze the inclined surfaces of the card blocks 7, which can push the card blocks 7 to one side and squeeze the spring 8. The two card blocks 7 are as follows. Figure 3 As shown, the arrangement is axially symmetrical, with a limit ring 9 fixedly provided at the outer end of the two connecting rods 6. The connecting rod 6 is movably arranged through the limit ring 9. The limit ring 9 plays a role of limiting. At the same time, the corresponding block 7 can be pulled to move by the limit ring 9.

[0028] It also includes a rotating assembly, which includes a mounting block 15, a rotating block 16 and a turning handle 17. A valve stem is installed on the valve body 1. The valve stem is the existing technology and controls the opening and closing of the valve body 1. The mounting block 15 is fixedly set on the valve stem. A card slot is set on the mounting block 15. The rotating block 16 is matched with the card slot. The rotating block 16 and the card slot are both hexagonal. The rotating block 16 can be stuck into the card slot. The turning handle 17 is fixed on the rotating block 16. The turning handle 17 can facilitate the rotation of the valve stem. An anti-lost rope 18 is fixed on the turning handle 17. The other end of the anti-lost rope 18 is fixed on the valve stem. The anti-lost rope 18 can prevent the turning handle 17 from being lost.

[0029] The detailed working process of this utility model is as follows:

[0030] 1. During installation, the staff first aligns the outer tube 3 with the connecting tube 2, and sets the sleeve 10 on the annular block 4, then tightens the sleeve 10, driving the outer tube 3 and the fixing ring 11 to move, so that the first sealing gasket 13 is tightly against the fixing ring 11, and the second sealing gasket 14 is tightly against the outer side of the annular block 4. At the same time, the two clamping blocks 7 can be clamped into the corresponding clamping holes 12, and when the sleeve 10 is rotated, the corresponding clamping holes 12 can squeeze the inclined surfaces of the two clamping blocks 7, pushing the two clamping blocks 7 and squeezing the corresponding springs 8. When the sleeve 10 is tightened, the two clamping blocks 7 can be clamped into the corresponding clamping holes 12, clamping the sleeve 10 to prevent the sleeve 10 from reversing and loosening. The installation method at both ends is the same;

[0031] 2. When in use, the staff inserts the rotating block 16 into the card slot, and then rotates the valve stem through the turning handle 17 to control the opening and closing of the valve body 1. When not in use, the rotating block 16 can be pulled out to avoid accidentally touching the turning handle 17 and causing the valve body 1 to open or close;

[0032] 3. When disassembling, the staff first pulls the limit ring 9 outward to drive the two clamping blocks 7 to move and separate from the corresponding clamping holes 12. At this time, the sleeve 10 can be rotated in the opposite direction to separate from the annular block 4 to complete the disassembly. The disassembly method at both ends is the same.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
