Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.
The utility model provides a simple structure's separation and reunion formula hand wheel.
In this embodiment, refer to fig. 1-3, this simple structure's separation and reunion formula hand wheel, including valve rod 1 and hand wheel, the hand wheel includes ring 2, connection pad 3 and is used for connecting the connecting rod 4 of ring and connection pad, still includes clutch spring 5, connection pad and connecting rod sliding connection, the connection pad bottom is equipped with separation and reunion boss 6, is located to be equipped with spring step 7 on the valve rod of connection pad below, be equipped with the separation and reunion recess 8 that is used for separation and reunion boss card to go into on the spring step, clutch spring one end links firmly with the spring step, and the other end links firmly with the connection pad, and this clutch spring has the elasticity that breaks away from in the separation and reunion recess with the separation and reunion boss.
The hand wheel among the above-mentioned technical scheme adopts separation and reunion formula structure, is in the state of often leaving between hand wheel and the valve rod, only when needing to operate the valve, is connected at hand wheel and valve rod, just can operate the valve, can not cause the accident to open and close the valve because of the maloperation, improves opening and close stability and the security of valve, has simple structure, advantage with low costs.
The specific principle is as follows: the hand wheel and the valve rod are in a normally-disengaged state, namely the hand wheel separates the clutch step on the connecting disc from the clutch groove on the spring step under the elastic force action of the clutch spring, so that the connection relationship between the hand wheel and the valve rod is released, and the valve rod cannot be driven to move by rotating the hand wheel at the moment. And when the valve rod needs to be operated, the clutch step on the connecting disc is pressed into the clutch groove by hand to realize connection between the hand wheel and the valve rod, and at the moment, the valve rod can be operated by the hand wheel.
Specifically, the connecting disc is in sliding fit with the connecting rod through a sliding sleeve 9; the clutch boss and the clutch groove are of mutually matched frustum structures; the bottom of the clutch groove is provided with a layer of first magnetic blocks 10, and the top of the clutch boss is provided with a layer of second magnetic blocks 11 which are mutually attracted with the first magnetic blocks.
The clutch boss and the clutch groove are of frustum structures, so that the clutch boss can be clamped into the clutch groove more smoothly to achieve connection. In addition, the first magnetic block and the second magnetic block are arranged on the clutch boss and the clutch groove, so that the connection between the clutch boss and the clutch groove is more stable and reliable.
Specifically, the valve rod is in threaded connection with a gland 12, and an indication mark for indicating the clutch state is arranged on the gland; the indicating mark comprises an indicating rod 13 and an indicating spring 14, the indicating rod is movably arranged in a through hole 15 of the gland, a spring groove 16 is arranged in the through hole, an indicating step 17 is arranged on the indicating rod in the spring groove, the indicating spring is sleeved on the indicating rod, one end of the indicating spring abuts against the indicating step, and the other end of the indicating spring abuts against the top wall of the spring groove.
The indicating mark is arranged and used for indicating the clutch state, and the connecting disc jacks up the indicating rod in the separation state, so that the indicating rod protrudes out of the surface of the connecting disc to indicate the separation state. And after the hand wheel is connected with the valve rod, the connecting disc is far away from the indicating rod, and the indicating rod is pulled back to the through hole under the elastic force of the indicating spring.
The skilled person should understand that: although the present invention has been described in accordance with the above embodiments, the inventive concept is not limited to this embodiment, and any modification of the inventive concept will be included in the scope of the patent claims.
