Detailed Description

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. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-4, an embodiment of the present utility model is provided: a valve, comprising a valve body 1 and a packing gland 2 arranged on the valve body 1, wherein the upper surface of the packing gland 2 is connected with a dial 3; a hand wheel 4 is further arranged on the packing gland 2, and the hand wheel 4 is connected with a valve rod 6 arranged in the valve body 1; the hand wheel 4 comprises an outer shell 40, and a pointer 5 and a driving part 42 are arranged on the outer wall surface of the outer shell 40; the inside of the outer casing 40 is linked with a boss 7 provided on the valve rod 6 through a connection port 45 provided.

In summary, the hand wheel 4 of the device can drive the pointer 5 to rotate on the dial 3 while realizing the rotation of the valve rod 6, so that the rotation angle of the valve rod 6 can be controlled; through optimizing the structure of the hand wheel 4, the structure of the hand wheel 4 is simple and novel, and the normal rotation of the valve rod 6 can be ensured; secondly, the driving part 42 is connected with an external force application rod, so that the rotation of the valve rod 6 is lighter, and the force application rod is convenient to assemble and disassemble with the driving part 42, so that the force application rod is convenient to take down, and the space occupation of the hand wheel 4 is reduced; thirdly, the hand wheel 4 has no complex wheel-shaped structure and strip-shaped structure with fluctuation, so that the whole structure of the hand wheel 4 is simpler, and the production and manufacturing cost of the hand wheel 4 are reduced.

Furthermore, since the dial 3 is movably mounted on the packing gland 2, and the diameters of the dial 3 and the upper end surface of the packing gland 2 are equal, the dial 3 can be used for covering the packing gland 2, a plurality of scale sections can be arranged on the dial 3, and the numerical value of each scale section is 0-90 degrees; thus, when one of the scale sections is worn, the dial 3 is rotated.

Further, since the inner part of the hand wheel 4 is also provided with a sleeve hole 43; wherein, one end of the sleeve hole 43 is sleeved on the valve rod 6, and the other end of the sleeve hole 43 is communicated with the connecting port 45. Therefore, when the sleeve hole 43 is clamped on the outer wall surface of the valve rod 6, the boss 7 can smoothly enter the connecting port 45; secondly, after the trepanning 43 contacts with the outer wall of the valve rod 6, the contact area between the hand wheel 4 and the valve rod 6 can be increased, so as to ensure that the hand wheel 4 cannot fall off from the valve rod 6 during rotation.

On the basis of the above scheme, the driving part 42 is internally provided with the screw hole 44, so that an external force application rod is conveniently in threaded fit with the screw hole 44, the stable and reliable position of the force application rod after installation is ensured, and the problem that personnel are injured easily due to weak contact of the force application rod in the rotation process of the hand wheel 4 is solved; further, since the screw hole 44 is connected to the inner portion of the outer housing 40, the stud on the force applying rod may also abut against the valve rod 6 after being screwed, so as to further enhance the contact stability between the hand wheel 4 and the valve rod 6.

Further, the number of the driving parts 42 is three, and three driving parts 42 are circumferentially arrayed on the outer casing 40. Therefore, the hand wheel 4 can be driven to rotate at least from three directions, so that the space requirement for driving the hand wheel 4 is reduced, namely, when one space is smaller, the force application rod can be installed from the place where the other space is larger, so that the hand wheel 4 can be driven to rotate.

Because the outer shell 40 is further provided with the mounting surface 41 which is convenient for mounting the pointer 5, the inner threaded hole is convenient to be formed, and meanwhile, one surface of the pointer 5 is convenient to be attached to a plane, so that the pointer 5 is reliably connected to the outer shell 40, and the problems that the contact is unstable and the pointer 5 is easy to shake when the curved surface of the outer shell 40 is contacted with the plane of the pointer 5 are solved.

Further, the cross sections of the boss 7 and the connecting port 45 are polygonal. For example hexagonal, thus allows the hand wheel 4 to more reliably drive the valve stem 6 in rotation, while also facilitating the direct mounting of the hand wheel 4 on other valve stems having hexagonal prisms.

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.
