Technical Field
[0001] This utility model relates to the field of valves, and in particular to a valve using a butterfly handle. Background Technology
[0002] The existing ball valve mainly consists of a ball valve body, a ball valve body, a connecting rod, a connecting platform, and a handle. The ball valve body is located inside the ball valve body, and the connecting rod is limited inside the ball valve body by the connecting platform. The handle and the ball valve body are connected by the connecting rod. When in use, the handle drives the ball valve body to rotate through the connecting rod, thereby opening and closing the ball valve.
[0003] In existing designs, the handles mainly use long handles or common ring handles. However, for valves in some narrow areas, it is difficult to use long handles, and it is not easy to limit the rotation angle and position the rotation angle using ring handles. Therefore, there is a need for a valve with a butterfly handle that can limit the rotation angle, position the rotation state, and has a simple structure that makes it easy for users to turn the valve. Utility Model Content
[0004] The main purpose of this utility model is to provide a valve with a butterfly handle that can limit the rotation angle, position the rotation state, has a simple structure, and is easy for users to turn.
[0005] This utility model proposes a valve using a butterfly handle, including a ball valve housing, a ball valve body, a connecting rod, a connecting platform, and a handle. The ball valve body is disposed inside the ball valve housing, and the connecting rod is limited and disposed inside the ball valve housing by the connecting platform. The two ends of the connecting rod are respectively connected to the handle and the ball valve body. By rotating the handle, the handle drives the ball valve body to rotate through the connecting rod, thereby realizing the opening and closing of the valve.
[0006] The handle is characterized in that it has a lever block shaped like butterfly wings on both sides of the top of the handle, and a handle through hole in the middle of the handle. The handle can be connected to the connecting rod by the cooperation of the handle through hole and the connecting rod through hole.
[0007] The bottom of the handle is provided with a handle limiting seat, and the top of the connecting platform is provided with multiple connecting platform connecting holes. By setting a limiting screw in the connecting platform connecting hole, the rotation angle of the handle can be limited by the cooperation of the limiting screw and the handle limiting seat.
[0008] The handle limiting seat is provided with a handle connection hole that is adapted to the connection hole of the connection platform. The handle connection hole and the connection platform connection hole are connected by screws to position the rotation state of the handle.
[0009] Preferably, the actuating block is provided with a handle anti-detachment hole, one end of the anti-detachment rope is connected to the handle anti-detachment hole, and the other end of the anti-detachment rope is connected to the connecting platform. By providing the handle anti-detachment hole and connecting it with the anti-detachment rope, the safety during use can be improved.
[0010] Preferably, a square handle connecting groove is provided on the inner side of the handle through hole at the bottom of the handle, and the top of the connecting rod is adapted to the shape of the handle connecting groove, so that the connecting rod can be rotated by the handle.
[0011] Preferably, the connecting platform has four connecting holes, which are arranged at equal angles around the center of the connecting platform, so that the handle can rotate at an angle of 90°.
[0012] The beneficial effects of this utility model using a butterfly handle valve are as follows:
[0013] 1. The lever with butterfly wing-shaped lever makes it easy for users to turn the handle, making it convenient to use in confined areas.
[0014] 2. By setting a handle limit seat, it can cooperate with the limit screw on the connecting platform to limit the rotation angle of the handle.
[0015] 3. By setting anti-slip holes on the handle and using them in conjunction with anti-slip ropes, the safety of using the handle can be improved. Attached Figure Description

[0022] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0023] Reference Figures 1 to 4 An embodiment of the valve using a butterfly handle according to this utility model is proposed:
[0024] A valve using a butterfly handle includes a ball valve housing 3, a ball valve body, a connecting rod 4, a connecting platform 2, and a handle 1. The ball valve body is disposed inside the ball valve housing 3, the connecting platform 2 is fixedly connected to the ball valve housing 3, and the connecting rod 4 is limited and disposed inside the ball valve housing 3 by the connecting platform 2. One end of the connecting rod 4 is connected to the ball valve body.
[0025] The top of the connecting platform 2 has four connecting holes 21, which are equally spaced around the center of the connecting platform 21. One of the connecting holes 21 contains a limit screw 22. The top of the connecting rod 4 has a handle through hole 41 in the middle, and the top cross-section of the connecting rod 4 is square.
[0026] The handle 1 has a through hole 15 in the middle, which mates with the connecting rod through hole 41 of the connecting rod 4, allowing the handle 1 to connect to the connecting rod 4. A square handle connecting groove 16 is provided on the inner side of the through hole 15 at the bottom of the handle 1. The top of the connecting rod 4 is fitted with the handle connecting groove 16, allowing the handle 1 to rotate the connecting rod 4. A handle limiting seat 12 is provided at the bottom of the handle 1. The rotation angle of the handle 1 is limited by the cooperation of the limiting screw 22 and the handle limiting seat 12, thus limiting the rotation angle of the handle 1 to 90°. The handle limiting seat 12 has a handle connecting hole 13 that mates with the connecting platform connecting hole 21. The handle connecting hole 13 is connected to the connecting platform connecting hole 21 by screws, thereby positioning the rotation state of the handle 1.
[0027] The top two sides of the handle 1 are equipped with butterfly-wing-shaped lever blocks 11, which make it easy for the user to rotate the handle 1 and use it in confined areas. The lever blocks 11 are equipped with handle anti-slip holes 14. One end of the anti-slip rope is connected to the handle anti-slip hole 14, and the other end of the anti-slip rope is connected to the connecting platform 2. The anti-slip rope improves safety during use.
