Technical Field

[0001] The utility model relates to the technical field of valve maintenance tools, in particular to a pneumatic butterfly valve maintenance auxiliary device. Background Art

[0002] At present, when a pneumatic butterfly valve is stuck open or closed, it is necessary to remove the fixed baffle of the pneumatic head limit switch and use an open / flexible wrench to force it to open or close. The operation is difficult and the fixed baffle of the limit switch is easily damaged if the operation is not careful. It is not only inefficient but also easy to cause damage to the equipment. When reinstalling the limit switch, the plastic indicator cover of the double-color ball is easily damaged. Therefore, a pneumatic butterfly valve maintenance auxiliary device is proposed.

[0005] Furthermore, the clip is designed in an "L"-shaped structure, and a webbing hole is provided on an edge of the clip away from the Japanese clip.

[0006] Furthermore, the day-type card is provided with two sets of channels, and one side channel is used to insert the lever, so that the day-type card and the lever form an "L"-shaped structure and are located on the outside of the card.

[0007] Furthermore, the high-strength polyester webbing is located in the webbing perforation at both ends away from the clamp to surround the valve, and extends to the channel between the clamp and the Japanese-type clamp through which the lever is inserted. At the same time, the high-strength polyester webbing rotates through the other side channel, passes between the clamp and the Japanese-type clamp, and extends out.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The utility model is designed that, according to the rotation direction of the valve, after the device is installed, the high-strength polyester webbing is tightened, and then the lever is pulled upwards to perform the "open / close" operation on the valve, and after the valve is rotated, the lever can be disengaged in time to prevent damage to the valve limiter installation baffle. The maintenance auxiliary device can repair the stuck fault of the pneumatic butterfly valve without removing the pneumatic butterfly valve limiter baffle. The operation is simple, and the maintenance personnel's fault handling efficiency can be effectively improved. There is no need to disassemble and install the limiter, and damage to the red and white plastic indicator cover of the limiter can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0014] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant literature, and several embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0015] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may also be a central 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 a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention. The terms used 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 in this article includes any and all combinations of one or more related listed items.

[0017] Example 1

[0018] like Figure 1-2As shown, the utility model provides a technical solution: a pneumatic butterfly valve maintenance auxiliary device, including a clamp 1 that is in contact with the installation position, a Japanese clamp 2, a high-strength polyester webbing 3 and a lever 4. The clamp 1 is a fulcrum for the entire device to drive the pneumatic valve to move. The Japanese clamp 2 is a connecting device for the lever 4 and the high-strength polyester webbing 3, and is the main force-bearing component. The high-strength polyester webbing 3 is a connecting device for the clamp 1 and the Japanese clamp 2. The lever 4 is the main force-bearing component of the entire device. The high-strength polyester webbing 3 is connected to the clamp 1 around the installation position and connected to the Japanese clamp 2. The installation position is the valve (the installation position is referenced Figure 2 ), and the day-type clamp 2 is arranged on the lever 4, and the lever 4 is inserted between the clamp 1 and the butterfly valve mounting frame.

[0019] Example 2

[0020] like Figure 1-2 As shown, the clip 1 is designed in an "L"-shaped structure, and a webbing hole 11 is provided on an edge of the clip 1 away from the Japanese clip 2 .

[0021] Two groups of channels 21 are provided on the day-type clamp 2 , and one side channel 21 is used to insert the lever 4 , so that the day-type clamp 2 and the lever 4 form an “L”-shaped structure and are located outside the clamp 1 .

[0022] The high-strength polyester webbing 3 is located in the webbing perforation 11 with both ends away from the clamp 1 to surround the valve, and extends to the channel 21 between the clamp 1 and the day-type clamp 2 through the lever 4. At the same time, the high-strength polyester webbing 3 rotates through the other side channel 21, passes between the clamp 1 and the day-type clamp 2 and extends out, thereby completing the installation of the high-strength polyester webbing 3.

[0023] Working principle: According to the rotation direction of the valve, the clamp 1 is pressed against the installation position of the pneumatic butterfly valve that needs to be repaired, that is, on the valve. The design of the clamp 1 enables it to fit firmly on the valve to prevent the valve from moving during maintenance. Then the valve is wrapped around the high-strength polyester webbing 3, and the high-strength polyester webbing 3 is extended to between the clamp 1 and the Japanese-type clamp 2 and through the channel 21 where the lever 4 is inserted. The high-strength polyester webbing 3 is then rotated through the channel 21 on the other side, passed between the clamp 1 and the Japanese-type clamp 2 and extended out. Then the high-strength polyester webbing 3 is tightened and fixed to the valve. Then the lever 4 is pulled upward to perform the "open / close" operation on the valve. After the valve rotates, the lever 4 can be disengaged in time to prevent damage to the valve limiter mounting baffle.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
