Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be embodied in many other forms different from those described herein and similar modifications may be made by those skilled in the art without departing from the spirit and scope of the invention and, therefore, the invention is not to be limited to the specific embodiments disclosed below.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a single embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 2, the adjustable limiting device for the valve comprises a valve body 1, a handle 2, a limiting block 3, a limiting seat 4 and a clamping assembly 5, wherein the limiting block 3 and the limiting seat 4 are both installed at the upper end of the valve body 1, an insertion rod 21 is arranged at the end part of the handle 2, the insertion rod 21 penetrates through one end of the limiting block 3 to be connected with the valve body 1, the other end of the limiting block 3 is movably inserted into the limiting seat 4, the clamping assembly 5 is installed on the limiting block 3, and the clamping assembly 5 is movably clamped with the limiting seat 4. Specifically, in this embodiment, the valve is the ball valve form, and 2 tip of handle are provided with inserted bar 21, and inserted bar 21 runs through stopper 3 in proper order and is connected with valve body 1 after, and in order to realize turning handle 2, stopper 3 follows handle 2 and rotates in step, sets up inserted bar 21 and stopper 3's joint department into square or other polygons, and it can for square or other polygon shape also to correspond the design for the hole of stopper 3 corresponding inserted bar 21. Further, when handle 2 removes assigned position on the valve body 1, open or close valve body 1 back, in order to avoid other personnel mistake touching handle 2, lead to the improper switching of valve body 1, consequently, the one end of keeping away from handle 2 at stopper 3 is provided with joint subassembly 5, is provided with spacing seat 4 at the limit portion of valve body 1, and joint subassembly 5 follows stopper 3 and rotates in step, before rotating, separates joint subassembly 5 and spacing seat 4. At the moment, the handle 2 can drive the clamping component 5 to normally rotate through the limiting block 3 without being blocked by the clamping component 5, when the handle 2 rotates to a preset position, an operator resets the clamping component 5 and clamps the limiting seat 4 again, at the moment, the handle 2 can be locked, the handle cannot rotate when being touched by mistake, and the valve is ensured to be in a normal state,

as shown in fig. 2 to 3, the clamping assembly 5 includes a spring seat 51, a lock block 52 and an adjusting handle 53, the spring seat 51 is installed on the limiting block 3, the lock block 52 is connected with the spring seat 51 through a spring column 521, one end of the adjusting handle 53 is connected with the spring seat 51, the other end of the adjusting handle 53 is movably clamped with the lock block 52, and one end of the lock block 52, which is far away from the spring seat 51, is movably abutted against the limiting seat 4. Specifically, when the device is used, the adjusting handle 53 is pulled, so that the spring column 521 is compressed or reset, and the locking block 52 is clamped with or separated from the limiting seat 4. When handle 2 needs to be rotated normally, need separate locking piece 52 and spacing seat 4 this moment, operating personnel can stir adjustment handle 53, compresses spring post 521 for locking piece 52 separates with spacing seat 4, just can make handle 2 normally rotate, otherwise the same reason.

As shown in fig. 1 to 2, the limiting seat 4 is arc-shaped, the inner side of the limiting seat 4 abuts against the limiting block 3, a slot 41 is formed in the outer side of the limiting seat 4, and the locking block 52 is movably inserted into the slot 41. Specifically, because the valve among this technical scheme is the ball valve, consequently be circular-arc with spacing seat 4 design to match the ball valve, in other valves, can design the spacing seat 4 of other shapes as required. The slot 41 is arranged on the limiting seat 4, so that the limiting block 3 can conveniently rotate along with the handle 2 without obstruction, and the locking block 52 can be movably inserted into the slot 41 under the driving of the spring column 521, so that the locking is stable.

As shown in fig. 2 to 3, the upper end surface of the lock piece 52 is conical, and the corresponding surface of the slot 41, which is in contact with the lock piece 52, is also a wedge-shaped surface, so that the contact area between the lock piece 52 and the slot 41 is increased, the contact friction force is increased, and when the spring column 521 is compressed, no contact between the lock piece 52 and the slot 41 is ensured, and the rotation of the handle 2 is smoother.

As shown in fig. 3, the upper end surface of the locking block 52 is provided with a clamping position 522, the clamping position 522 is stepped, the adjusting handle 53 is clamped in the clamping position 522, and when the adjusting handle 53 is clamped in the clamping position 522 with an unequal distance from the handle 2, the spring column 521 can be controlled to be compressed or reset, so that the locking block 52 is controlled to abut against or separate from the limiting seat 4, and the effect of locking in a stationary state is achieved. In other embodiments, the adjusting handle 53 may be designed to be turned upside down, i.e. one end is hinged to the spring seat 51 and the other end is movably clamped to the locking block 52.

As shown in fig. 1 to 2, a clamping disc 11 is arranged at the upper end of the valve body 1, the limiting block 3 is movably abutted against the end of the clamping disc 11, and the clamping disc 11 is matched with the limiting block 3 to limit the rotation angle of the handle 2.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
