The pneumatic diaphragm valve is used as a common cut-off valve and widely applied to the fields of pump valves in various industries such as industrial water treatment, pharmaceutical industry, boiler heating and ventilation, semiconductor special gas supply systems and the like. Because the pneumatic diaphragm valve contains more parts which are mostly fixed in a screw connection mode, a common wrench is usually used for loosening or screwing the nut during disassembly and assembly, but the jaw of the existing wrench is parallel to the wrench body, so that the wrench is difficult to extend into a machine for disassembly and assembly; and because contain a plurality of adjacent or perpendicular nuts in the tiny part of part, generally need two spanners to carry out the centre gripping to two nuts, the effect of one of them spanner prevents that the part from rocking, and the effect of another spanner is the dismantlement nut, because the main part of ordinary spanner is longer, and when centre gripping nut, the handle all faces the user usually, leads to alone hardly using these two spanners with both hands simultaneously, and this time and the operation that has just greatly restricted dismouting personnel. Based on this, the present application provides a disassembling tool for conveniently disassembling a pneumatic diaphragm valve, and the present application is described in detail below with reference to the accompanying drawings and alternative embodiments.

As shown in fig. 1, which is a schematic view of a disassembling tool 100 for a pneumatic diaphragm valve, as an embodiment of the present application, the present application discloses a disassembling tool 100 for a pneumatic diaphragm valve, which specifically includes a main body 110, a fixed pull lip 120 and a handle 130 that are integrally formed, the fixed pull lip 120 and the handle 130 are respectively disposed at two ends of the main body 110, and the shape of the main body 110 may be a cylinder, a square, an ellipse, etc., which is not limited herein; it is important to note that the fixed pulling lip 120 is perpendicular to the main body 110, and the handle 130 is aligned with the main body 110, that is, the combined pattern formed by the fixed pulling lip 120, the main body 110 and the handle 130 is L-shaped.

In addition, a slide rail 111 is arranged in the main body 110, the opening direction of the slide rail 111 is the same as the extending direction of the fixed pull lip 120, a movable pull lip 140 is arranged in the slide rail 111, the movable pull lip 140 slides in the slide rail 111, the movable pull lip 140 is also vertical to the main body 110, and a clamping opening is formed between the movable pull lip 140 and the fixed pull lip 120 and used for clamping a nut or a part, so that when the nut or the part is clamped, the size of the clamping opening can be adjusted at any time, the pull lip is prevented from slipping, and the outer edge structure of the nut or the part is damaged. The main body 110 further has a rotating wheel groove 112, the rotating wheel groove 112 is provided with a rotating wheel 160, the sliding rail 111 is provided with a rotating shaft 150, the rotating wheel 160 is engaged with the rotating shaft 150, and the rotating wheel 160 is rotated to drive the rotating shaft 150 and the movable wrench lip 140 to move along the track of the sliding rail 111 in the sliding rail 111.

The opening direction of the rotating wheel groove 112 can be perpendicular to the extending direction of the fixed pull lip 120, so that when a user holds the handle 130, the rotating wheel 160 can be conveniently rotated by a thumb to adjust the size of the clamping opening; of course, the opening direction of the runner groove 112 may also be the same as or opposite to the extending direction of the fixed plate lip 120, and may be designed according to the usage habit of the user.

The shaft pin 150 is parallel to the central axis of the main body 110, and one end of the shaft pin is fixed to the movable wrench lip 140, and the shaft pin and the movable wrench lip can be integrally formed, so that the stability between the shaft pin and the movable wrench lip is improved, the number of parts in the disassembling tool 100 is reduced, and the assembling is convenient. The surfaces of the shaft pin 150 and the rotating wheel 160 are both provided with threads, the threads of the shaft pin 150 and the rotating wheel 160 are matched with each other, and the shaft pin 150 is driven to move in the sliding rail 111 by rotating the rotating wheel 160; one end of the slide rail 111 extends to the orthographic projection of the fixed plate lip 120, and the other end of the slide rail 111 extends to the orthographic projection of the rotating wheel 160, so that the minimum distance between the movable plate lip 140 and the fixed plate lip 120 in the dismounting tool 100 is zero, that is, the movable plate lip 140 can be attached to the fixed plate lip 120, when the dismounting tool 100 is not used, the movable plate lip 140 can be attached to the fixed plate lip 120, and dirt or water vapor is prevented from being attached to the surfaces, attached to the movable plate lip 140 and the fixed plate lip 120, to cause corrosion and influence on the fixation of a clamped object. The largest distance between the movable pull lip 140 and the fixed pull lip 120 in the disassembling tool 100 is the distance between the fixed pull lip 120 and the rotating wheel 160, and the disassembling tool 100 can be used for disassembling as long as the size of a clamped object does not exceed the range; moreover, the distance between the movable pulling lip 140 and the fixed pulling lip 120 is not large, and the rotating shaft is matched with the rotating wheel 160, so that the shaft pin 150 cannot fall off from the sliding rail 111.

The dismounting tool 100 in the application has a simple structure, is convenient to manufacture and easy to operate, and the movable pull lip 140 and the fixed pull lip 120 in the dismounting tool 100 are perpendicular to the main body 110, so that when the pneumatic diaphragm valve is dismounted, the movable pull lip 140 and the fixed pull lip 120 can extend into a smaller gap to clamp corresponding nuts or parts; when small objects are screwed, the required torque is small, and after the disassembling tool 100 in the application is adopted, a user can hold the top of the main body 110 with a hand, so that the disassembling tool is more convenient to disassemble and assemble, is convenient to extend into a machine for overhauling, and is greatly convenient for the disassembling time of an overhauling person; when two vertical or parallel nuts are clamped by using two disassembling tools 100, the handle 130 is perpendicular to the arm direction of a user, so that the user can conveniently and simultaneously operate the two disassembling tools 100, and the assembling and disassembling process is more convenient and smooth.
