Description of the embodiments

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

Referring to fig. 1-4, an embodiment of the present utility model is provided: an operating handle for a valve comprises a valve body 1, a valve rod 2 and a packing gland 4, wherein the valve rod 2 and the packing gland 4 are arranged on the valve body 1; the valve rod 2 is also provided with a driving piece 3, the driving piece 3 comprises a support frame 30 movably connected with the valve rod 2, and one end of the support frame 30 is provided with a through hole 34; the fastener 33 is connected with the connecting hole 6 on the packing gland 4 in a matching way after penetrating through the through hole 34, so as to fix one end of the driving piece 3 on the packing gland 2.

In summary, the driving member 3 is driven to rotate, so that the valve rod 2 can be driven to rotate, and meanwhile, after the valve rod 2 rotates to a predetermined position, the driving member 3 can be fixed on the packing gland 4 by connecting the fastener 33 with the connecting hole 6, so as to lock the position of the valve rod 2. Based on this, the valve handle shake is reduced while ensuring that the driver 3 is reliably locked, and the valve stem seal is compromised, especially in a simpler structure than in the prior art.

Further, the middle part of the support frame 30 is provided with the notch 36 sleeved outside the valve rod 2, and the support frame 30 is fixed on the valve rod 2 through the connecting piece 31, so that the valve rod 2 and the support frame 30 are convenient to assemble and disassemble, and maintenance cost and assembly cost of the handle are reduced.

Specifically, the connecting piece 31 enters from one side of the notch 36 and passes through the valve rod 2 completely and then passes through the other side of the notch 36 again to be connected with the nut 32, so that the valve rod 2 and the support frame 30 are convenient to assemble; secondly, the connecting piece 31 is ensured to be stably positioned on the support frame 30, so that the stability of the support frame 30 and the valve rod 2 after being assembled is ensured; thirdly, the support frame 30 is further convenient to rotate by taking the connecting piece 31 as a rotation center shaft, so that one end of the support frame 30 is conveniently separated from the packing gland 4.

Since the support 30 contacts with the upper surface of the packing gland 4 through the contact portion 35, and the through hole 34 completely penetrates through the contact portion 35, an included angle is formed between the cross section of the support 30 and the upper surface of the packing gland 4 while the fastener 33 is connected with the connecting hole 6, so that the driving rod 5 is conveniently installed, and the driving rod 5 is conveniently driven to rotate the driving member 3.

On the basis of the above scheme, the support frame 30 is movably connected with the driving rod 5, so that the driving rod 5 can be mounted on the support frame 30 for a long time according to the requirement, and the driving rod 5 can be taken down according to the requirement, so that the space occupation of the driving rod 5 is reduced.

Further, because the driving rod 5 and the internal thread hole 37 arranged on the end face of the support frame 30 are in threaded fit, the driving rod 5 is simple and convenient to disassemble and assemble, and the driving rod 5 can be reliably connected with the support frame 30 after being assembled, so that the problem that the driving piece 3 is in rotation failure due to the fact that the driving rod 5 and the support frame 30 are not firmly connected is avoided.

Furthermore, since the number of the connecting holes 6 is plural, and the plurality of connecting holes 6 are circumferentially arrayed on the upper surface of the packing gland 4, the position of the driving member 3 is stable and reliable after the driving member 3 is connected with the connecting holes 6 at different positions, especially, the angle value between any two adjacent connecting holes 6 is equal, for example, when the angle between any two adjacent connecting holes 6 is 15 degrees; one ensures that the angles of each rotation of the driving piece 3 are equal; and secondly, the rotating angle of the valve rod 2 can be known by calculating the number of the driving parts 3 passing through the connecting holes 6.

In particular, the inner wall of the connecting hole 6 is provided with an internal thread, and the fastening member 33 is connected with the connecting hole 6 in a matching manner through the external thread of the outer wall thereof. The harm to the valve caused by handle shake is further reduced while the driving member 3 is ensured to be reliably locked.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
