Description

Technical Field

[0001] This utility model belongs to the technical field of valve handle testing tools, and relates to a handle angle testing tool, particularly a valve handle angle testing tool. Background Technology

[0002] Currently, valves, especially ball valves, are equipped with handles. The handles are used to link the rotation of the valve ball in the valve body to control the opening and closing of the fluid. Usually, valves have two limit protrusions to limit the rotation of the handwheel, which represent the opening and closing of the valve passage.

[0003] However, existing handles may have inaccurate machining precision during processing, resulting in deflection errors. This causes the valve ball to fail to rotate to the precise position. When the handle is rotated to the limit protrusion, the ball valve also has deflection errors, affecting fluid flow and valve sealing angle, leading to water leakage. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a valve handle angle detection tool for detecting valve handle accuracy and preventing deflection errors.

[0005] The objective of this utility model can be achieved through the following technical solution: a valve handle angle detection tool, the handle including a handle mounting hole for mounting on a valve, characterized in that the angle detection tool includes a base, a handle and a nut, the handle having a hole, the top of the base having a screw passing through the hole, the nut being locked onto the screw to fix the base to the handle, the top of the screw having a positioning rod for insertion into the handle mounting hole, and the handle having two detection contacts, the central axes of the two detection contacts being perpendicular to each other.

[0006] In the valve handle angle detection tool described above, there is a rounded transition section between the detection contact and the handle.

[0007] Compared with existing technologies, this valve handle angle detection tool has the advantage of clearly feeding back the deflection accuracy of the handle, so as to prevent valves from being assembled with unqualified handles that have not been tested, which would cause problems in the assembly process and inconvenience in later use, and prevent valve leakage.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 , Figure 3 As shown, this valve handle angle detection tool includes a handle 1 with a handle mounting hole 2 for mounting on the valve. The tool comprises a base 3, a handle 4, and a nut 5. The handle 4 has a hole, and the top of the base 3 has a screw 6 passing through the hole. The nut 5 is locked onto the screw 6 to fix the base 3 to the handle 4. The top of the screw 6 has a positioning rod 7 for insertion into the handle mounting hole 2. The handle 4 has two detection contacts 8, whose central axes are perpendicular to each other. The two detection contacts 8 detect the rotation of the handle 1 by 90 degrees forward and 90 degrees backward, respectively. This rotation angle is the angle at which the handle 1 rotates when the valve is opened or closed. First, regarding the forward rotation... During the 90-degree rotation test, align the handle mounting hole 2 of handle 1 with the positioning rod 7 and slowly insert it. If the end face of the handle 1 is in contact with the end face of the test contact 8 and can be fully inserted into the positioning rod 7, it indicates that the angle test of handle 1 in that direction is qualified. Then, perform the rotation test in the opposite direction of 90 degrees. Again, if the end face of handle 1 is in contact with the end face of the test contact 8 and can be fully inserted into the positioning rod 7, it indicates that the angle test of handle 1 in that direction is qualified. In other words, by performing angle tests on the handles at both ends of handle 1, if the positioning rod 7 cannot be fully inserted, that is, if the two end faces cannot be in contact, there is an angle deviation in handle 1, which is unqualified.

[0014] Preferably, there is a rounded transition section between the detection contact 8 and the handle 4.

[0015] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0016] Although this document frequently uses terms such as handle 1, handle mounting hole 2, base 3, handle 4, nut 5, screw 6, positioning rod 7, and detection contact 8, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
