Description

Technical Field

[0001] The utility model relates to the technical field of valve maintenance, in particular to a stop valve wheel disc anti-dropping device. Background Art

[0002] The decarbonization device has dense valves and high operating frequency. The control and feedback of valves are very important in the production process. Once the control valve fails, it will affect the production. Therefore, the stability of the valve switch feedback signal directly plays an important guiding role in the operation. However, after a period of operation, the feedback disc of the valve feedback device frequently becomes loose and unreliable. Since there are 265 valves in this device and the operation is frequent, once multiple failures occur, it will not only affect the operation, but also cause the risk of misjudgment, production reduction or even shutdown.

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0021] For ease of description, spatial relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature shown in a figure relative to another element or feature. It should be understood that the spatial terms are intended to include different orientations of the device in use or operation in addition to the orientation shown in the figures. For example, if the device in the figure is inverted, elements described as being "below" other elements or features will be positioned "above" the other elements or features. Thus, the exemplary term "below" may include both upper and lower orientations.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] The utility model is described in detail below in conjunction with the accompanying drawings: A stop valve wheel disc anti-slip device of the utility model comprises a sleeve 1, the bottom side wall of the sleeve 1 is provided with an opening 2 along a circumferential array, the inner wall opening 2 at the bottom of the sleeve 1 is provided with an anti-slip pattern 3, and the bottom opening 2 of the sleeve 1 is provided with a clamp 4, and the sleeve 1 is locked to the lower part of the wheel disc of the stop valve shaft through the clamp 4; the outer wall of the sleeve 1 is provided with a thread 5, and a nut 6 is installed at the thread 5, a support seat matching the sleeve 1 is slidably installed on the sleeve 1, an L-shaped groove 9 is provided in the support seat, a first support block 10 is slidably installed at the top surface of the support seat on the L-shaped groove 9, and a second support block 11 is slidably installed at the inner wall of the support seat on the L-shaped groove 9, and rubber blocks 13 are provided on the first support block 10 and the second support block 11, and a connecting rod is hinged on the first support block 10, and the other end of the connecting rod is hinged to the second support block 11.

[0024] The first support block 10 and the second support block 11 are both provided with travel grooves, and a clamping block 14 matching the travel grooves is provided in the L-row grooves located on the top surface of the support seat and in the L-shaped grooves 9 located on the inner wall of the support seat.

[0025] The support seat is two semicircular seats 7 that are interlocked with each other. Mounting seats 8 are arranged on both sides of the semicircular seat 7. Mounting holes are arranged on the mounting seats 8. The two semicircular seats 7 are locked with bolts. The interlocking structure can facilitate the installation and disassembly of the support seat and the replacement of the aged rubber block 13.

[0026] A spherical groove is provided at the bottom of the second mounting block, and a ball 15 is installed in the spherical groove. A groove 16 matching the ball 15 is provided at the bottom of the L-shaped slot 9. The design of the ball 15 can effectively reduce the friction of the second support block 11.

[0027] When the utility model is in use, the sleeve 1 needs to be pre-installed on the valve shaft. After the sleeve 1 is moved to a suitable position, the sleeve 1 is locked to the valve shaft through the clamp 4, and then the two semicircular seats 7 are locked to the top of the nut 6 through bolts. During installation, the rubber block 13 on the top of the support seat should be pushed to the wheel disc and lowered; after the support seat is installed, the support seat is driven to move upward by rotating the nut 6 until the nut 6 cannot be screwed, so that the device can play a good supporting role on the wheel disc. When the rubber block 13 on the first support block 10 pushes to the bottom of the wheel disc, the first support block 10 will move downward, and the second support block 11 will move toward the valve shaft through the driving of the connecting rod. The position of the device on the valve shaft can be made more stable by pushing the rubber block 13 on the second support block 11 to the valve shaft.

[0028] By installing this device on the stop valve, the stop valve disc can be effectively prevented from sliding down, and the valve detection signal loss caused by the loosening of the disc can be avoided, thereby affecting production.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
