Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] The present utility model provides a technical solution: As Figure 1 and Figure 4 shown, in this embodiment, an assembled valve that is convenient for disassembly and assembly includes a valve body 1. Flange bodies 2 are fixedly connected to both ends of the valve body 1. An auxiliary structure 6 is clamped at the left end of the valve body 1. Two fixing cylinders 7 are fixedly connected to the outside of the valve body 1. A retaining ring 8 is clamped inside the valve body 1. Two limiting structures 5 are rotatably connected inside the retaining ring 8. A valve flap 9 is provided on the back of the retaining ring 8. The valve flap 9 is connected to the opposite surfaces of the two limiting structures 5. The auxiliary structure 6 is fixedly connected to the outside of the retaining ring 8. The limiting structure 5 is rotatably connected inside the fixing cylinder 7. A mounting rod 3 is rotatably connected inside the fixing cylinder 7;

[0022] The limiting structure 5 is connected to the outer surface of the mounting rod 3. The limiting structure 5 includes two sleeves 501, two clamping blocks 502, a rotating ring 504 and a fixing ring 505. Two clamping grooves 503 are opened inside the two sleeves 501. Two bolts 506 are fixedly connected above the rotating ring 504. Nuts 507 are threadedly connected to the outside of the two bolts 506.

[0023] As Figure 1 and Figure 2 shown, the auxiliary structure 6 includes a sealing ring 601 and two L-shaped plates 602. A snap ring 604 is fixedly connected to the right side of the sealing ring 601. A positioning groove 603 is opened on the left side of the sealing ring 601. The two L-shaped plates 602 are fixedly connected to the outer surface of the retaining ring 8. The distance between the two L-shaped plates 602 is the same. The snap ring 604 is clamped at the left end of the valve body 1. The L-shaped plate 602 is clamped inside the valve body 1. The L-shaped plate 602 is clamped inside the positioning groove 603.

[0024] By setting the L-shaped plates 602 and 602, when the sealing ring 601 is clamped to the left end of the valve body 1, the L-shaped plate 602 on the surface of the retaining ring 8 will slide inside the valve body 1 when it is connected to the valve body 1. After the L-shaped plate 602 slides, it will be clamped into the positioning groove 603, so as to lock the position of the sealing ring 601, avoid the loosening of the sealing ring 601 at the left end of the valve body 1, and the L-shaped plate 602 plays a certain limiting role in fixing the retaining ring 8, avoiding the phenomenon that the position of the retaining ring 8 deviates when it is fixed to the valve body 1.

[0025] As Figure 3 and Figure 4 shown, two sleeves 501 are rotatably connected in the cavity opened on the right side of the retaining ring 8. The opposite ends of the two sleeves 501 are fixedly connected to the outer surface of the valve flap 9. The distance between the two sleeves 501 is the same. The block 502 is clamped in the slot 503. The rotating ring 504 is rotatably connected in the fixed cylinder 7. The fixed ring 505 is fixedly connected to the outer surface of the mounting rod 3. Two bolts 506 are clamped in the fixed ring 505. The bolt 506 is lapped with the fixed ring 505 through the nut 507. A handwheel 4 is fixedly connected to the outside of the mounting rod 3.

[0026] By setting the block 502, the slot 503 and the rotating ring 504, when the valve flap 9 is connected to the mounting rod 3, the block 502 on the surface of the mounting rod 3 will slide in the slot 503 when the mounting rod 3 penetrates the fixed cylinder 7. When the block 502 contacts the end of the slot 503, the mounting rod 3 will be fixed to the fixed ring 505, so that the slot 503 plays a certain guiding role in fixing the mounting rod 3. And through the cooperation between the block 502 and the slot 503, the valve flap 9 can rotate with the mounting rod 3. Since the fixed ring 505 is connected to the rotating ring 504 through the bolt 506 and the nut 507, when the mounting rod 3 rotates, the rotating ring 504 will rotate on the surface of the fixed cylinder 7, so that the rotating ring 504 plays a certain auxiliary role in the rotation of the mounting rod 3, avoiding the collision between the mounting rod 3 and the fixed cylinder 7 when the mounting rod 3 rotates.

[0027] The utility model provides an assembled valve which is convenient for disassembly and assembly. The specific working principle is as follows:

[0028] When the valve is connected to a pipeline for use, the sealing ring 601 is clamped to the left end of the valve body 1 through a snap ring 604. After the retaining ring 8 slides on the valve body 1 through the L-shaped plate 602, it will contact the limiting ring inside the valve body 1. When the L-shaped plate 602 slides inside the valve body 1, it will be clamped in the positioning groove 603. When the retaining ring 8 and the valve flap 9 are in position with the valve body 1, the sleeve 501 on the surface of the valve flap 9 will contact the fixed cylinder 7. When the mounting rod 3 is inserted through the fixed cylinder 7, the clamping block 502 on the surface of the mounting rod 3 will slide in the card slot 503, and the two bolts 506 above the rotating ring 504 will be inserted through the fixed ring 505. When the clamping block 502 contacts the end of the card slot 503, after the nut 507 is threadedly connected to the bolt 506, it will contact the fixed ring 505, so that the retaining ring 8 and the valve flap 9 can be fixed inside the valve body 1. Then, the handwheel 4 is fixedly connected to the outer surface of the mounting rod 3. When a turning force is applied to the mounting rod 3 through the handwheel 4, the valve flap 9 will rotate automatically with the cooperation of the clamping block 502 and the card slot 503.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
