[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0030] like Figures 1 to 3As shown, the valve disassembly auxiliary tool 100 of the embodiment of the utility model, the valve includes a valve body 201 and a valve core 202, the valve disassembly auxiliary tool 100 includes a support frame 1, a stop member 2 and a pulling assembly 3; the support frame 1 has a accommodating cavity 111 for accommodating the valve body 201, and the cavity wall of the accommodating cavity 111 has a first stop portion 112 for stopping the valve body 201; the stop member 2 is connected to the support frame 1, and the stop member 2 has a second stop portion 21 for stopping the valve body 201, and the first stop portion 112 and the second stop portion 21 are relatively arranged on both sides of the accommodating cavity 111; the pulling assembly 3 includes a telescopic member 31 and a pulling member for connecting the valve core 202, the telescopic member 31 includes a fixed portion 311 and a telescopic portion 312, the fixed portion 311 is connected to the support frame 1, the telescopic portion 312 is telescopically connected to the fixed portion 311, and the pulling member is connected to the telescopic portion 312.

[0031] The valve disassembly auxiliary tool 100 of the embodiment of the utility model is mainly used to assist maintenance personnel in disassembling the valve core 202 of the self-sealing valve. When disassembling the valve core 202, the valve body 201 can be placed in the accommodating cavity 111, and the valve body 201 can be fixed by the first stop portion 112 and the second stop portion 21. Then, the pulling piece is connected to the valve core 202, and the pulling piece can be driven to move by moving the telescopic portion 312 relative to the fixed portion 311, so as to pull the valve core 202 outward, thereby realizing the disassembly of the valve core 202, and the operation is more convenient and labor-saving.

[0032] In addition, when the valve core 202 is difficult to pull out, a greater pulling force can be applied to the valve core 202 through the telescopic member 31 and the pulling member. Compared with the method of prying open with the help of tools in the related art, it is more convenient to disassemble the valve core 202 and it is not easy to cause damage to the valve core 202, sealing ring and other components.

[0033] like Figure 3 As shown, before disassembling the valve core 202, the valve cover, valve stem and other components of the valve need to be removed. The valve body 201 has a first stop surface 2011 and a second stop surface 2012. The first stop surface 2011 has an opening through which the valve core 202 can be pulled out.

[0034] As an example, Figure 1 and Figure 3 As shown, the first stop surface 2011 and the second stop surface 2012 are both planes and parallel to each other. The shape of the first stop portion 112 matches the shape of the first stop surface 2011, and the shape of the second stop portion 21 matches the shape of the second stop surface 2012. The valve body 201 is placed in the accommodating cavity 111, and the first stop portion 112 stops the first stop surface 2011, and the second stop portion 21 stops the second stop surface 2012, so that the valve body 201 can be clamped and fixed.

[0035] In other embodiments, when the first stop surface 2011 or the second stop surface 2012 is a curved surface, the shapes of the first stop portion 112 and the second stop portion 21 can also be adaptively adjusted, and the valve body 201 can be clamped and fixed by the first stop portion 112 and the second stop portion 21, so as to ensure the stability of the valve body 201 when the valve core 202 is pulled out.

[0036] In some embodiments, Figure 1 As shown, the support frame 1 includes a support seat 11, a bearing seat 12 and a support rod 13. The bearing seat 12 and the support seat 11 are arranged at an interval, and the bearing seat 12 and the support seat 11 are connected through the support rod 13. The fixing part 311 is connected to the bearing seat 12; a slide 14 is slidably provided on the support rod 13, and the telescopic part 312 and the pulling member are both connected to the slide 14.

[0037] By arranging the bearing seat 12 and the supporting seat 11 at intervals, a sliding space can be reserved for the drawing piece; by providing the slide 14, the sliding stability of the drawing piece can be improved.

[0038] As an example, Figure 1 and Figure 2 As shown, when the valve disassembly auxiliary tool 100 is in use, the socket is arranged above the support seat 11, the fixing part 311 is fixed to the upper side of the socket by bolts, the telescopic part 312 passes through the socket and extends to the upper side of the slide 14 and is connected to the slide 14; the socket is in the shape of a rectangular plate, the number of support rods 13 is four, the four support rods 13 are respectively arranged at the four corners of the socket, the slide 14 is arranged between the support seat 11 and the socket, and the four support rods 13 all pass through the slide 14, so that the slide 14 slides smoothly, thereby making the puller slide smoothly.

[0039] In some embodiments, Figure 2 As shown, the support seat 11 includes a top plate 113, a bottom plate 114 and a side plate 115, and the top plate 113, the bottom plate 114 and the side plate 115 surround the above-mentioned accommodating cavity 111, and the bearing seat 12 is arranged on the side of the top plate 113 away from the bottom plate 114; the top plate 113 has a makeshift groove 116 for the valve core 202 to pass through, and the makeshift groove 116 is connected to the accommodating cavity 111, and the pulling piece can pass through the makeshift groove 116 to connect with the valve core 202.

[0040] The provision of the clearance groove 116 can prevent the valve core 202 from colliding with the support seat 11 when being pulled out.

[0041] As an example, Figure 1 and Figure 2As shown, the clearance groove 116 divides the top plate 113 into two parts. The side wall of the top plate 113 facing the bottom plate 114 forms the above-mentioned first stop portion 112. The stop member 2 is installed on the bottom plate 114, and the side wall of the stop member 2 facing the top plate 113 forms the second stop portion 21.

[0042] The side plates 115 are arranged between the top plate 113 and the bottom plate 114 . There are three side plates 115 . The three side plates 115 form three side cavity walls of the accommodating cavity 111 , so that one side of the accommodating cavity 111 is open so that maintenance personnel can place the valve body 201 into the accommodating cavity 111 .

[0043] Optionally, the bottom of the support base 11 is provided with supporting legs, and the supporting legs are fixedly connected to the bottom plate 114, and the support base 11 can be supported on a supporting surface such as the ground, a work surface, etc. through the supporting legs.

[0044] As a result, a space is reserved between the support seat 11 and the support surface to facilitate the installation of the stop member 2.

[0045] In some embodiments, Figure 3 As shown, the valve core 202 has a threaded hole 2021 , and the pulling member is a pulling rod 32 . The pulling rod 32 is inserted into the threaded hole 2021 and is threadably matched with the hole wall of the threaded hole 2021 .

[0046] As is known, the valve stem of the self-sealing valve is inserted into the valve core 202 and is threadedly matched with the valve core 202 so as to control the rotation of the valve core 202 through the valve stem, thereby controlling the on-off of the valve. Therefore, the valve core 202 has a threaded hole 2021. After the valve stem is removed, the threaded hole 2021 on the valve core 202 is exposed.

[0047] By matching the pull rod 32 with the threaded hole 2021 on the valve core 202, the pull rod 32 can be tightly connected to the valve core 202 without damaging the valve core 202. Then, the valve core 202 can be pulled out by applying a pulling force to the pull rod 32 through the telescopic part 31, which is convenient to operate.

[0048] In some embodiments, the pull rod 32 is rotatably connected to the slide table 14 .

[0049] The pull rod 32 is rotatable relative to the slide 14 , and the pull rod 32 can be connected to the lock core by rotating the pull rod 32 . Compared with the method of connecting the pull rod 32 to the lock core by rotating the valve body 201 , the operation is more convenient.

[0050] In some embodiments, Figure 3 and Figure 4As shown, the valve disassembly auxiliary tool 100 also includes a limit member 4, which includes a sliding rod portion 41 and a limit member 42 that are connected to each other. The slide 14 has a through hole, and the aperture of the through hole is larger than the outer diameter of the sliding rod portion 41. The sliding rod portion 41 is inserted into the slide 14, and the pulling rod 32 is connected to the sliding rod portion 41. The limit member 42 is arranged at one end of the sliding rod portion 41 away from the pulling rod 32.

[0051] Under the threaded cooperation between the pull rod 32 and the valve core 202, the pull rod 32 is rotated so that the pull rod 32 is gradually inserted into the threaded hole 2021 of the valve core 202, so that the pull rod 32 and the valve core 202 can be connected. According to the above arrangement, the slide rod portion 41 is penetrated in the through hole, and the slide rod portion 41 can realize two actions of rotation and sliding relative to the slide table 14, so that the pull rod 32 can rotate relative to the slide table 14, and can also move relative to the slide table 14 along its own length direction, so that it is more convenient to connect the pull rod 32 with the lock core.

[0052] Alternatively, if Figure 4 As shown, the telescopic portion 312 is connected to the slide 14 via a connecting frame 5, the connecting frame 5 includes a connecting plate 51 and four connecting rods 52, the connecting plate 51 is stably connected to the slide 14 via the four connecting rods 52, so that there is a gap between the connecting plate 51 and the slide 14, and the limiting portion 42 is arranged in the gap.

[0053] Therefore, the telescopic portion 312 and the pulling member 32 correspond to each other along the sliding direction thereof, and are both arranged at the center of the slide table 14 , so that the pulling member 32 can be more stably controlled when moving by the telescopic member 31 .

[0054] In some embodiments, Figure 4 As shown, a force-applying portion 43 is sleeved on the slide rod portion 41 , the force-applying portion 43 and the limit member 4 are arranged on both sides of the slide 14 , and the outer side surface of the force-applying portion 43 has a plurality of protrusions, which are arranged at intervals along the circumference of the pulling rod 32 .

[0055] The force-applying portion 43 is provided to facilitate maintenance personnel to rotate the pull rod 32 . In addition, the plurality of protrusions on the force-applying portion 43 can increase the friction force when maintenance personnel hold the force-applying portion 43 , thereby further increasing the convenience of rotating the pull rod 32 .

[0056] Alternatively, if Figure 4 As shown, the force applying portion 43 is a first knob.

[0057] Optionally, a mounting block 141 is fixedly provided on the lower side of the slide 14, and the mounting block 141 is in the shape of a rectangle. The slide rod portion 41 passes through the slide 14 and the mounting block 141. The slide rod portion 41 can rotate relative to the slide 14 and can move along its own length direction. The force-applying portion 43 is arranged on the side of the mounting block 141 away from the slide 14.

[0058] Thereby, the stability of the connection between the stopper 4 and the slide 14 can be improved, thereby improving the stability of the connection between the pull rod 32 and the slide 14 .

[0059] In some embodiments, Figure 2 As shown, the stop member 2 is movably connected to the support frame 1 .

[0060] After the valve body 201 is placed in the accommodating cavity 111 , by adjusting the position of the stop member 2 , the valve body 201 can be clamped by the first stop portion 112 and the second stop portion 21 , thereby improving the stability of the valve body 201 and making it easier to pull out the valve core 202 .

[0061] In some embodiments, the stop member 2 includes a stop rod 22 , which passes through the support frame 1 and is threadedly engaged with the support frame 1 .

[0062] Through the above arrangement, the movement of the stop member 2 can be controlled by rotating the stop stem, and the operation is relatively simple.

[0063] like Figure 2 As shown, the stop rod 22 passes through the bottom plate 114 and is threadedly engaged with the bottom plate 114. The second stop portion 21 is disc-shaped and fixedly connected to the upper end of the stop rod 22. A second knob 23 is provided at the lower end of the stop rod 22 to improve the convenience of maintenance personnel in turning the stop rod 22.

[0064] In some embodiments, Figure 1 and Figure 2 As shown, the telescopic member 31 is an electric push rod, the housing of the electric push rod forms a fixed portion 311 , and the push rod of the electric push rod forms a telescopic portion 312 .

[0065] By adopting an electric push rod as the telescopic member 31, compared with telescopic members 31 such as air cylinders and oil cylinders, it is more energy-saving, environmentally friendly and safer.

[0066] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present invention.
