For this reason, a tubular flange ball valve is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tubular flange ball valve to solve the problem that in the prior art, it is not convenient to filter impurities in the water quality during the use of the existing tubular flange ball valve. Since various fine impurities are mixed in the water quality, when the water quality passes through the tubular flange ball valve for a long time, the impurities in the water quality are likely to cause the parts in the ball valve to jam, thus affecting the flexible use of the tubular flange ball valve.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] As Figures 1-4 shown, the present invention provides a technical solution: a tubular flange ball valve, including a tubular flange ball valve body 1. Since the ball valve is made of stainless steel, it can avoid rust inside the ball valve and pollute the water quality, making the ball valve more environmentally friendly and safer to use. A valve pipe 101 is fixedly connected to the side end of the tubular flange ball valve body 1, a ring plate 102 is fixedly connected to the side end of the valve pipe 101, and a sealing ring 103 is installed on the side end of the ring plate 102, which can improve the waterproof performance when the ring plate 102 is installed with other pipes. A plurality of slots 104 are opened on the inner side of the ring plate 102, and round grooves 107 are spaced apart from the side ends of each slot 104. A filtering mechanism is provided between the inside of each slot 104 and the inside of the valve pipe 101. A supporting component for supporting the filtering mechanism is provided on the inner side end of the valve pipe 101. A limiting mechanism for installing the filtering mechanism is provided inside each round groove 107. During implementation, after the filtering mechanism is installed and fixed in the valve pipe 101 through the limiting mechanism, the filtering mechanism is supported and limited by the supporting component, making the installation of the filtering mechanism in the valve pipe 101 more stable. Therefore, by installing the filtering mechanism in the valve pipe 101, the present device can filter impurities in the flowing water quality during the use of the tubular flange ball valve body 1, so that the parts inside the tubular flange ball valve body 1 are not easily stuck, thus avoiding affecting the flexible use of the tubular flange ball valve body 1.

[0021] As an implementation manner in this embodiment, as Figure 1 and Figure 4As shown in the figure, the filtering mechanism includes an installation cylinder 2, which is inserted into the interior of the valve pipe 101. A plurality of insertion plates 201 are fixedly connected to the side end of the installation cylinder 2, and each insertion plate 201 is inserted into each slot 104. A jack 203 is provided at the side end of each insertion plate 201, and a pulling groove 202 is provided at the side end of the installation cylinder 2. A limiting plate 205 is fixedly connected to the side end of the installation cylinder 2 away from the pulling groove 202. A multi-stage filter element 204 is fixedly installed inside the installation cylinder 2. In implementation, by installing the multi-stage filter element 204 inside the valve pipe 101, impurities in the flowing water quality can be filtered during the use of the tubular flange ball valve body 1. Since the multi-stage filter element 204 can filter various fine impurities in the water quality, it is not easy to cause the parts inside the tubular flange ball valve body 1 to get stuck, thus avoiding affecting the flexible use of the tubular flange ball valve body 1.

[0022] Furthermore, the support assembly includes a limiting platform 105, which is fixedly connected to the inner wall of the valve pipe 101. A limiting groove 106 is provided at the side end of the limiting platform 105, and the limiting plate 205 is inserted into the limiting groove 106. In implementation, by aligning the insertion plate 201 with the slot 104 and inserting the installation cylinder 2 into the valve pipe 101, at this time, the limiting plate 205 is inserted into the limiting groove 106, and the limiting platform 105 limits and supports the position of the installation cylinder 2, making the installation of the installation cylinder 2 in the valve pipe 101 more stable.

[0023] As an implementation method in this embodiment, as Figure 2 and Figure 3 shown in the figure, the limiting mechanism includes a circular plate 3, which is inserted into the circular groove 107. A circular rod 301 is fixedly connected to the side end of the circular plate 3, and the side end of the circular rod 301 penetrates to the outer end of the ring plate 102. A pulling head 302 is fixedly connected to the side end of the circular rod 301. A spring 303 is sleeved on the outer end of the circular rod 301. An insertion rod 304 is fixedly connected to the side end of the circular plate 3, and the insertion rod 304 is adapted to the jack 203. In implementation, by pulling the pulling heads 302 at both ends, the circular rod 301, the circular plate 3 and the insertion rod 304 are driven to move in the circular groove 107. At this time, the circular plate 3 can press against the spring 303 to contract. When each insertion rod 304 is not limited in the slot 104, by aligning the insertion plate 201 with the slot 104 and inserting the installation cylinder 2 into the valve pipe 101, at this time, the limiting plate 205 is inserted into the limiting groove 106, and the limiting platform 105 limits and supports the position of the installation cylinder 2, making the installation of the installation cylinder 2 in the valve pipe 101 more stable. At this time, after the insertion plate 201 is inserted into the slot 104, the jack 203 is aligned with the position of the insertion rod 304. At this time, after releasing the pulling head 302, the spring 303 can push the circular plate 3 to rebound, driving the insertion rod 304 to insert into the jack 203, thereby fixing the position of the insertion plate 201 in the slot 104, facilitating the installation and fixation of the installation cylinder 2 and the multi-stage filter element 204, and also facilitating the disassembly of the multi-stage filter element 204.

[0024] Working principle: By pulling the pull tabs 302 at both ends, the round rod 301, the round plate 3 and the plug rod 304 are driven to move in the round groove 107. At this time, the round plate 3 can press against the spring 303 for contraction. When each plug rod 304 is not limited in the slot 104, by aligning the plug plate 201 with the slot 104, the installation cylinder 2 is inserted into the valve pipe 101. At this time, the limit plate 205 is inserted into the limit groove 106, and the limit platform 105 limits and supports the position of the installation cylinder 2, making the installation of the installation cylinder 2 in the valve pipe 101 more stable. At this time, after the plug plate 201 is inserted into the slot 104, the jack 203 is aligned with the position of the plug rod 304. At this time, after releasing the pull tab 302, the spring 303 can push the round plate 3 to rebound, driving the plug rod 304 to insert into the jack 203, thereby fixing the position of the plug plate 201 in the slot 104, facilitating the installation and fixation of the installation cylinder 2 and the multi-stage filter element 204, and also facilitating the disassembly of the multi-stage filter element 204. Therefore, by installing the multi-stage filter element 204 in the valve pipe 101, this device can filter impurities in the flowing water quality during the use of the tube flange ball valve body 1. Since the multi-stage filter element 204 can filter various fine impurities in the water quality, it is not easy to cause jams in the parts inside the tube flange ball valve body 1, thus avoiding affecting the flexible use of the tube flange ball valve body 1.
