Description

Technical Field

[0001] This utility model belongs to the field of ball valve technology, and in particular relates to an externally controlled, sealed, and easily disassembled ball valve. Background Technology

[0002] A ball valve is a type of valve that uses a ball as the opening and closing element to control the flow of water. An externally controlled ball valve refers to a valve whose ball rotation can be controlled by an external handwheel. Ball valves have inlet and outlet connections. When water flows into the valve body through the inlet connection, it flows through the opening and closing hole in the center of the ball to the outlet connection, and finally flows into the outlet pipe for use. However, in practical use, it still has the following drawbacks:

[0003] When a ball valve is in operation, it is installed between two pipelines that need to control the flow of fluid. During installation, various mounting bolts and nuts need to be installed one by one. During disassembly, the mounting bolts and nuts need to be removed one by one. The disassembly process is relatively complicated and not convenient to use.

[0004] When a ball valve needs to be opened or closed during operation, the valve's opening and closing settings can be changed simply by turning the handwheel or other positions. Because the ball valve's internal valve core is spherical, there is less friction between it and the valve body, so the torque required for opening and closing is small, and only a 90-degree rotation is needed to change the valve's opening and closing. However, if there is accidental contact or the opening and closing angle is too large during operation, the opening and closing status of the ball valve will change, and the accuracy of using the ball valve is not good. Utility Model Content

[0005] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide an externally controlled, easily disassembled ball valve. By incorporating a ball shell, rotating column, fixed column, mounting plate, and L-shaped mounting plate, it solves the problems of inconvenient disassembly during ball valve operation, as well as the ease with which accidental contact during operation can alter the opening and closing status and result in inaccurate opening and closing.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an externally controlled, easily detachable ball valve, comprising a ball shell, a rotating column, a fixed column, a mounting plate, and an L-shaped mounting plate. The rotating column is movably connected to the upper part of the ball shell. An L-shaped rotating bracket is fixed to the top of the rotating column. A connecting pipe is symmetrically fixed and connected to the periphery of the ball shell. A mounting plate is fixed to the end of the connecting pipe away from the ball shell. A movable sleeve is fixed in a circular array at the edge of the mounting plate near the ball shell. An L-shaped mounting plate is movably connected inside the movable sleeve. A fixing plate is fixed on the short side of the inner side of the mounting plate away from the mounting disc. A clamping bolt is threaded through the fixing plate. A fixing column is fixed on the upper part of the periphery of one of the connecting pipes. During operation, the valve core is movably connected to the ball shell, and the L-shaped rotating bracket is connected to its top end by the rotating column. The mounting bolt is threadedly connected to the L-shaped rotating bracket by rotating it, and the mounting bolt is movably connected by the fixing column to limit the position of the rotating column. The mounting disc is installed with the external mounting structure, and the L-shaped mounting plate clamps the mounting disc and the external mounting structure together.

[0007] Furthermore, the upper outer side of the spherical shell has a movable opening, and the rotating column is movably connected through the movable opening. The connecting pipe is horizontally arranged, and when the spherical shell is working, it is movably connected to the rotating column through the movable opening.

[0008] A valve core is fixed at the bottom of the rotating column. The valve core is movably connected inside the spherical shell. Both ends of the L-shaped rotating frame are provided with threaded holes. A mounting bolt is threaded into the threaded hole above the connecting pipe. When the rotating column is working, the valve core rotates to change the on / off state of the two connecting pipes.

[0009] The top center of the fixed column has an insertion hole, and the screw part of the mounting bolt below the L-shaped rotating frame is inserted into the insertion hole. When the fixed column is working, the mounting bolt is movably connected through the insertion hole.

[0010] The mounting plate has a ring array of magnetic rods inserted through it. A limiting block is fixed to the end of the magnetic rod near the spherical shell, and a sealing ring is fixed to the end of the mounting plate away from the connecting pipe. The mounting plate is inserted into the structure to be installed through the magnetic rods, so that the mounting plate and the external mounting structure are properly positioned to restrict each other during operation.

[0011] The L-shaped mounting plate is attached to the end face of the mounting plate, and the head of the clamping bolt in the fixing plate is located at the end of the fixing plate away from the mounting plate, so that the clamping bolt is clamped to the structure of the mounting plate.

[0012] In use, this utility model solves the problem of inconvenient disassembly of ball valves by setting up a ball shell, mounting plate, and L-shaped mounting plate. When disassembly is required, simply loosen the clamping bolts and remove the L-shaped mounting plate from the movable sleeve. Then, pull the limiting block and pull the magnetic rod out of the mounting plate to remove the ball shell, making disassembly more convenient.

[0013] This invention solves the problems of accidental activation and inaccurate opening and closing of ball valves by incorporating a ball shell, rotating column, and fixed column. During operation, the corresponding structures are installed in suitable positions. To maintain valve core flow, the L-shaped rotating bracket is rotated until the valve core is open. The mounting bolt is then screwed into the threaded hole on the L-shaped bracket until its threaded portion is inserted into the socket on the fixed column, thus controlling the position of the rotating column. To open the valve, the mounting bolt is rotated until it exits the threaded hole, then rotated again until another threaded hole on the L-shaped bracket aligns with the socket on the fixed column. The mounting bolt is then screwed into the threaded hole and inserted into the socket on the fixed column, completing the operation. By controlling the position of the L-shaped bracket and the ball shell with the mounting bolt, accidental activation and alteration of the valve core's opening and closing behavior are prevented. This design ensures precise control of the valve's opening and closing, reducing the risk of accidental activation and guaranteeing that the valve core rotates exactly 90 degrees during operation, resulting in improved accuracy.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0024] Please see Figure 1-4 This utility model is an externally controlled, sealed, and easily detachable ball valve, including a ball shell 1, a rotating column 2, a fixed column 3, a mounting plate 4, and an L-shaped mounting plate 5. The rotating column 2 is movably connected to the upper part of the ball shell 1. When the ball shell 1 is in operation, the valve core 201 is movably connected therein. The rotating column 2 rotates, causing the valve core 201 in the ball shell 1 to rotate. An L-shaped rotating bracket 202 is fixed to the top of the rotating column 2, with its corners set at right angles. The L-shaped rotating bracket 202 increases the torque when rotating the valve core 201. A connecting pipe 102 is symmetrically fixed and connected to the periphery of the ball shell 1. The mounting plate 4 is fixed to the end of the connecting pipe 102 away from the ball shell 1. When the ball shell 1 is in operation, the connecting pipe 102... The connecting pipe 102 is connected to the mounting plate 4. The mounting plate 4 is used to connect to the installation structure on the pipeline that needs to be connected. The mounting plate 4 has a movable sleeve 403 fixed in a ring array at one end edge near the spherical shell 1. The movable sleeve 403 is movably connected to the L-shaped mounting plate 5. The L-shaped mounting plate 5 is movably connected inside the movable sleeve 403. The inner side of the L-shaped mounting plate 5 away from the short side of the mounting plate 4 is fixed to the fixing plate 501. The fixing plate 501 is threadedly connected to the clamping bolt 502. The upper part of the periphery of the connecting pipe 102 is fixed to the fixing post 3. The fixing plate 501 is connected to the L-shaped mounting plate 5. The clamping bolt 502 is threadedly connected to the fixing plate 501.

[0025] Specifically, the upper outer side of the spherical shell 1 has an opening 101, and the rotating column 2 is movably connected inside the opening 101. The connecting pipe 102 is horizontally arranged. When the spherical shell 1 is working, it is movably connected to the rotating column 2 through the opening 101.

[0026] A valve core 201 is fixed at the bottom of the rotating column 2. The valve core 201 is movably connected inside the spherical shell 1. Both ends of the L-shaped rotating frame 202 are provided with threaded holes 203. The threaded holes 203 above the connecting pipe 102 are threaded with mounting bolts 204. When the valve core 201 rotates, it controls the opening and closing of the two connecting pipes 102. The L-shaped rotating frame 202 is threaded with mounting bolts 204 through the threaded holes 203.

[0027] The top center of the fixed column 3 has an insertion hole 301. The screw part of the mounting bolt 204 below the L-shaped rotating bracket 202 is inserted into the insertion hole 301. The mounting bolt 204 is rotated into the insertion hole 301 to restrict the position of the ball shell 1 and the rotating column 2, and to prevent the valve core 201 from being accidentally rotated and changing the opening and closing mode during operation.

[0028] In this embodiment, once the ball housing 1 is installed in its designated position, it can be opened and closed. During operation, by installing the corresponding structure in the appropriate position, when it is necessary to maintain the unobstructed flow of the valve core 201, the L-shaped rotating bracket 202 is rotated until the valve core 201 is open. Then, the mounting bolt 204 is screwed into the screw hole 203 on the L-shaped rotating bracket 202 until the screw portion of the mounting bolt 204 is inserted into the insertion hole 301 on the fixing rod, thus restricting the position of the rotating column 2. When opening, the mounting bolt 204 is rotated until it is unscrewed from the screw hole 203. Then, it is rotated again until another screw hole 203 on the L-shaped rotating bracket 202 is aligned with the insertion hole 301 on the fixing column 3. The mounting bolt 204 is then screwed into the screw hole 203 and inserted into the insertion hole 301 on the fixing column 3, thus completing the operation. The mounting bolt 204 restricts the position of the L-shaped rotating bracket 202 and the ball housing 1, preventing the valve core 201 from accidentally rotating and changing its opening and closing mode during operation. Specific Implementation Example 2

[0030] Please see Figure 1 , 2 5, 6. Based on the specific embodiment one, magnetic rods 401 are inserted in a ring array inside the mounting plate 4. A limiting block 402 is fixed to the end of the magnetic rod 401 near the spherical shell 1, and a sealing ring 404 is fixed to the end of the mounting plate 4 away from the connecting pipe 102. When the mounting plate 4 is working, the magnetic rods 401 are inserted into the mounting plate 4 and extend into the holes on the mounting structure, so that the relative position between the mounting plate 4 and the mounting pipe is limited during the working process, and the limiting block 402 limits the position of the magnetic rods 401 inserted into the mounting plate 4.

[0031] Specifically, the L-shaped mounting plate 5 is attached to the end face of the mounting plate 4, and the bolt head of the clamping bolt 502 in the fixing plate 501 is located at the end of the fixing plate 501 away from the mounting plate 4. When the L-shaped mounting plate 5 is working, it is installed by the clamping bolt 502 on the fixing plate 501.

[0032] The operation process of this embodiment is as follows: During operation, when installing the spherical shell 1, after setting the mounting plate 4 in the corresponding installation position, insert the magnetic rod 401 into the mounting plate 4, and then insert it into the installation structure on the pipeline at the installation position. After the position is fixed by the limiting block 402, insert the L-shaped mounting plate 5 into the movable sleeve 403, and then screw the clamping bolt 502 into the fixed plate 501 and press it onto the installation structure until the installation structure and the mounting plate 4 are pressed together, thus completing the work. When disassembly is required, simply loosen the clamping bolt 502 and remove the L-shaped mounting plate 5 from the movable sleeve 403. Then, pull the limiting block 402 to pull the magnetic rod 401 out of the mounting plate 4, and the spherical shell 1 can be removed, making disassembly more convenient.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
