Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valves, in particular to a butterfly valve device which is easy to disassemble. Background Art

[0002] A butterfly valve, also known as a flap valve, is a regulating valve with a simple structure, particularly suitable for the on-off control of low-pressure pipeline media. Its closing member (valve disc or butterfly plate) is a disc that rotates around the valve axis to achieve the purpose of opening and closing.

[0003] At present, in the prior art, a Chinese patent with announcement number CN220792078U discloses a butterfly valve that is easy to disassemble. The device easily turns the turntable handle through the lever principle. When disassembling the butterfly valve, one rod body passes through the through holes on the connector one and the connector three in sequence, and the other rod body passes through the through holes on the connector two and the connector four in sequence. The position of the valve body is fixed by a supporting force exerted on the rod body on the pipeline flange. When the fixing bolts on the left flange and the right flange are removed, the valve body will not fall off. However, in actual use, the rod body of the device is only a sliding connection, and there is no device to prevent the rod body itself from slipping. In view of this, we propose a butterfly valve device that is easy to disassemble. Utility Model Content

[0004] The main purpose of the utility model is to provide a butterfly valve device that is easy to disassemble and can solve the problems raised in the above background technology.

The setting of the positioning rod can make the running trajectory of the movable block more stable. The movable block is fixedly connected with a round rod, and the round rod is slidably connected to the connecting hole on the connecting piece. The rotating block is rotated ninety degrees by rotating the connecting plate by ninety degrees. At this time, the plug block is pulled out along the through groove on the fixed plate, thereby releasing the connection relationship between the fixed plate and the connecting block. At this time, the staff can grasp the two-way screw rod to fix the position of the valve body, thereby facilitating the subsequent disassembly of the butterfly valve, and the two-way screw rod is driven to rotate by rotating the rotating rod, thereby driving the two sets of movable blocks to move, so that the round rod is away from the connecting hole on the connecting piece, thereby completing the overall disassembly of the auxiliary mechanism.

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-Figure 5 The utility model proposes a butterfly valve device that is easy to disassemble, including a valve body 1, a flange 2 is fixedly connected to the outer wall of the valve body 1, a turntable handle 3 is provided above the valve body 1, a connecting piece 4 is provided on the flange 2, and a connecting hole is provided on the connecting piece 4, and an auxiliary mechanism 5 is provided on the valve body 1. The auxiliary mechanism 5 includes a connecting block 51, and the connecting block 51 is fixedly connected to the outer wall of the valve body 1, and a notch is provided on the connecting block 51.

[0026] In the embodiment of the utility model, in order to enable the auxiliary mechanism 5 to operate better, specifically, the slot is slidably connected with an insert block 57, the insert block 57 is movably connected with a connecting rod 511, one end of the connecting rod 511 is fixedly connected with a connecting plate 59, the other end of the connecting rod 511 is fixedly connected with a rotating block 510, the connecting rod 511 is fixedly connected with a torsion spring 58, one end of the torsion spring 58 away from the connecting rod 511 is fixedly connected to the outer wall of the insert block 57, the insert block 57 is movably connected with a fixed plate 54, and a through groove is provided on the fixed plate 54. The insert block 57 is inserted into the fixed plate 54 through the setting of the through groove, and then inserted into the slot on the connecting block 51.

[0027] The two-way screw rod 56 is fixedly connected to the fixing plate 54, and the two-way screw rod 56 is fixedly connected to the rotating rod 55. The two-way screw rod 56 is threadedly connected to the movable block 53. The setting of the positioning rod can make the running trajectory of the movable block 53 more stable. The movable block 53 is fixedly connected to the round rod 52, and the round rod 52 is slidably connected to the connecting hole on the connecting member 4. The connecting plate 59 is rotated ninety degrees to make the rotating block 510 rotate ninety degrees accordingly, so that the direction of the rotating block 510 is consistent with the direction of the notch and the through groove, and then the insert block 57 is inserted into the connecting block 51 along the through groove and the notch. At this time, the connecting plate 59 is loosened, and the rotating block 510 is driven to reset under the action of the torsion spring 58, so that the rotating block 510 is clamped in the notch of the connecting block 51, thereby completing the clamping work between the fixing plate 54 and the connecting block 51. The connecting plate 59 rotates ninety degrees to make the rotating block 510 rotate ninety degrees as well.

The above-mentioned valve body 1, flange 2, turntable handle 3 and connecting member 4 are similar to the principles mentioned in the Chinese patent with authorization announcement number CN220792078U (a butterfly valve easy to disassemble), and the same effect is achieved.

[0028] In the utility model, when it is necessary to disassemble the butterfly valve during use, the connecting plate 59 is first rotated ninety degrees to make the rotating block 510 rotate ninety degrees as well. At this time, the insert block 57 is pulled out along the through groove on the fixed plate 54, thereby releasing the connection between the fixed plate 54 and the connecting block 51. At this time, the staff can grasp the two-way screw rod 56 to fix the position of the valve body 1, so as to facilitate the subsequent disassembly of the butterfly valve. Finally, the rotating rod 55 is rotated to drive the rotation of the two-way screw rod 56, thereby driving the two sets of movable blocks 53 to move, so that the round rod 52 is away from the connecting hole on the connecting member 4, thereby completing the overall disassembly of the auxiliary mechanism 5.
