Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a butterfly valve capable of preventing accidental touch of a switch. Background Art

[0002] The butterfly valve, also known as the flap valve, is a simple regulating valve with a set of circular valve plates inside. The valve plates are driven to rotate by the top rotating shaft to achieve the purpose of opening and closing the internal channel of the valve body.

[0003] However, in actual use, in order to easily twist the valve plate during use, a set of torque handles perpendicular to the valve stem are usually installed on the top of the valve stem, and the valve stem is easily turned by the torque handles. However, in actual use, the long torque handles bring convenience but also cause the problem of accidental touch. The ends of the handles usually exceed the width of the valve body, which makes it easy for the opening and closing states to change due to accidental touch during use. For this reason, a butterfly valve with anti-accidental touch switch is provided to solve the above problem. Utility Model Content

However, in actual use, the long torque grips bring convenience while also causing the problem of accidental touch, and the end of the torque grips usually exceeds the width of the valve body, resulting in the problem that the opening and closing states are easily changed due to accidental touch during use.

[0033] The embodiment of the present application provides a butterfly valve with an anti-accidental-touch switch, which solves the problem that in order to facilitate and easily twist the valve plate during use, a set of torque grips perpendicular to the valve stem are usually installed on the top of the valve stem, and the valve stem is easily rotated by the torque grips. However, in actual use, the long torque grips bring convenience while also causing the problem of accidental touch, and the end of the torque grips usually exceeds the width of the valve body, resulting in the problem that the opening and closing states are easily changed due to accidental touch during use.

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] The utility model embodiment discloses a butterfly valve which can prevent accidental touch of the switch.

[0036] According to the attached Figure 1-5 As shown, it comprises a valve seat 1 and a valve plate 2 installed inside the valve seat 1, and a valve stem 3 is provided on the top of the valve plate 2 to prevent accidental touch;

[0037] The anti-accidental-touch valve stem 3 includes:

[0038] A hexagonal valve stem 31, which is fixedly connected to the valve plate 2;

[0039] Rotate the valve stem 32, which is rotatably disposed on the top of the hexagonal valve stem 31;

[0040] A transmission inner hexagonal sleeve 33, which is movably sleeved on the outer surfaces of the hexagonal valve stem 31 and the rotating valve stem 32;

[0041] A torque handle 35, which is fixedly mounted on the top of the rotating valve stem 32;

[0042] The outer wall of the valve seat 1 is provided with a fixing member 5 , and the fixing member 5 is used to fix the torque handle 35 .

[0043] A seat ring 6 is arranged inside the valve seat 1 , a sealing ring 7 is installed on the outer surface of the seat ring 6 , and the valve plate 2 is rotatably arranged inside the sealing ring 7 .

[0044] The outer wall of the valve seat 1 is fixedly welded with a valve tube 4 , the top end of the valve plate 2 is rotatably connected to the inside of the valve tube 4 , and the fixing member 5 is installed on the top of the valve tube 4 .

[0045] The fixing member 5 comprises:

[0046] A holder 51, which is welded to the outer wall of the top end of the valve tube 4;

[0047] The clamping column 52 is movably inserted into the inner walls of both sides of the clamping seat 51;

[0048] The locking spring 53 is disposed inside the holder 51 , and the end of the locking spring 53 abuts against the holder 52 .

[0049] The top end of the hexagonal valve stem 31 is horizontally rotatably connected to a hinge seat 36 , and the bottom end of the rotating valve stem 32 is movably hinged inside the hinge seat 36 .

[0050] A fixing bolt 34 is threadedly connected to the top of the rotating valve stem 32 , and the fixing bolt 34 is used to fix the torque handle 35 .

[0051] Working principle: When the device is in use, the torque handle 35 is turned to make the torque handle 35 drive the rotating valve stem 32 to rotate horizontally, and the outer surfaces of the rotating valve stem 32 and the hexagonal valve stem 31 are sleeved with a transmission inner hexagonal sleeve 33. Therefore, the torque handle 35 drives the hexagonal valve stem 31 to rotate through the transmission inner hexagonal sleeve 33, so that the valve plate 2 rotates, thereby realizing the normal opening and closing action of the valve. After the adjustment is completed, the transmission inner hexagonal sleeve 33 is pushed upward to remove the transmission inner hexagonal sleeve 33 from the outer surface of the hexagonal valve stem 31. At this time, the hinge seat 36 is rotated horizontally, so that the torque handle 35 coincides with the opening direction of the clamping seat 51. At this time, the rotating valve stem 32 is rotated downward by 90 degrees. At this time, the torque handle 35 enters the interior of the clamping seat 51. At this time, the torque handle 35 is limited by the clamping column 52, so that the torque handle 35 can be prevented from being touched accidentally, and the state of the valve plate 2 can also be fixed.

[0052] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0053] 1. Push the transmission hexagonal sleeve 33 upwards and then rotate the hinge seat 36 horizontally so that the torque handle 35 coincides with the opening direction of the clamping seat 51. At this time, rotate the valve stem 32 downward 90 degrees. At this time, the torque handle 35 enters the inside of the clamping seat 51. At this time, the torque handle 35 is limited by the clamping column 52, so that the torque handle 35 can be prevented from being accidentally touched, and the state of the valve plate 2 can also be fixed.

[0054] A locking spring 53 is provided on the back of the clamping column 52, and the locking spring 53 ensures that the clamping column 52 always protrudes from the outer surface of the torque handle 35, so that the torque handle 35 is restricted inside the clamping seat 51. Even if the entire valve seat 1 is installed inverted, the torque handle 35 can be folded and stored to prevent accidental touching.
