Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a ball valve that is easy to disassemble and maintain. Background Technology

[0002] A ball valve is a valve in which the opening and closing element is driven by the valve stem and rotates around the ball valve axis. Ball valves were first introduced in the 1950s. With the rapid development of science and technology and the continuous improvement of production processes and product structures, they have rapidly developed into a major type of valve in just 40 years.

[0003] The ball valve design commonly found on the market today uses a large number of bolts to ensure the stability of the connections between components. This makes disassembly and maintenance extremely inconvenient, requiring the removal of numerous bolts one by one, which is time-consuming and significantly impacts maintenance efficiency. Utility Model Content

[0004] This utility model relates to a ball valve that is easy to disassemble and maintain. It solves the problem that in the existing ball valve design, in order to ensure the stability of the connection between the components, a large number of bolts are generally used for fastening. This is extremely inconvenient during the later disassembly and maintenance, as many bolts need to be removed one by one, which takes a long time and affects the maintenance efficiency.

[0005] In a first aspect, this utility model provides a ball valve that is easy to disassemble and maintain, specifically comprising: a valve body A, a valve body B, a valve core, a sealing ring A, a sealing ring B, a rotating rod, a sealing ring C, a large nut, a rotating handle, a small nut, a rotating ring, and a bolt; the valve body A is internally connected to the valve body B, and the valve core, sealing ring A, and sealing ring B are installed inside the valve body A, with sealing ring B located between the valve body A and the valve core; a rotating rod is internally connected to the valve body A, with its bottom end inserted into the top of the valve core; a sealing ring C and a large nut are internally connected to the valve body A, with sealing ring C located between the large nut and the valve body A, and the rotating rod passing through the sealing ring C and the large nut; a rotating handle is connected to the top of the rotating rod, and a small nut is threadedly connected to the top of the rotating rod, with the bottom of the small nut contacting the rotating rod; a rotating ring is externally connected to the valve body A, and the rotating ring is connected to the valve body B, with a bolt internally connected to the rotating ring, and the bolt connected to the valve body A.

[0006] Furthermore, valve body B is slidably inserted into valve body A, valve body A is symmetrically provided with guide grooves on the outside, and valve body B is symmetrically provided with connecting blocks on the outside, with the connecting blocks slidably connected in the guide grooves.

[0007] Furthermore, the rotating ring is rotatably connected to the valve body A, a guide block is provided on the outside of the valve body A, and an arc-shaped hole is provided inside the rotating ring, with the guide block slidably connected in the arc-shaped hole.

[0008] Furthermore, the outer ring is provided with a slot, which is L-shaped and has an inclined surface inside. The slot is connected to the guide groove, and the end of the connecting block is connected to the slot.

[0009] Furthermore, the valve body A has a positioning hole on its exterior and a screw hole inside the rotating ring. When the connecting block is located at the innermost end of the slot, the positioning hole and the screw hole are connected.

[0010] Furthermore, the bolt is threaded into the threaded hole, and the bolt end is located in the positioning hole.

[0011] This utility model provides a ball valve that is easy to disassemble and maintain, and has the following beneficial effects:

[0012] In use, during the sliding insertion of valve body B into valve body A, the connecting block and guide groove slide together, providing a guiding effect and effectively preventing twisting between valve body B and valve body A. After the connecting block is connected to the guide groove, the end of the connecting block is in the slot. Rotating the block causes it to contact the inclined surface, which in turn moves valve body B inward, ensuring that sealing ring A and valve body A and valve core are in close contact, thus guaranteeing the sealing performance of the ball valve. When the end of the connecting block moves to the innermost end of the slot, the rotation effectively limits and fixes valve body B.

[0013] Furthermore, when the connecting block moves to the innermost end of the slot, the positioning hole and the screw hole are connected. Rotating the bolt moves the bolt end into the positioning hole, and the bolt fixes the rotating ring, thus ensuring the limiting and fixing effect of the rotating ring on valve body B. If valve body A and valve body B need to be separated for maintenance, rotate the bolt in the opposite direction to separate the bolt end from the positioning hole, release the rotating ring from the fixing, and rotate the rotating ring in the opposite direction to separate valve body A and valve body B. The operation is simple and quick.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: Please refer to Figures 1 to 4 :

[0026] This utility model proposes a ball valve that is easy to disassemble and maintain, comprising: valve body A1, valve body B2, valve core 3, sealing ring A4, sealing ring B5, rotating rod 6, sealing ring C7, large nut 8, rotating handle 9, small nut 10, rotating ring 11, and bolt 12; valve body B2 is internally connected to valve body A1, and valve core 3, sealing ring A4, and sealing ring B5 are installed inside valve body A1. Sealing ring B5 is located between valve body A1 and valve core 3, and between valve body B2 and valve core 3; a through-connection is provided inside valve body A1. Rotary rod 6, the bottom end of which is inserted into the top of valve core 3; a sealing ring C7 and a large nut 8 are connected inside valve body A1, the sealing ring C7 is located between the large nut 8 and valve body A1, and the rotary rod 6 passes through the sealing ring C7 and the large nut 8; a rotating handle 9 is connected to the top of rotary rod 6, and a small nut 10 is threaded to the top of rotary rod 6, the bottom of the small nut 10 is in contact with rotary rod 6; a rotating ring 11 is connected to the outside of valve body A1, the rotating ring 11 is connected to valve body B2, and a bolt 12 is connected inside the rotating ring 11, the bolt 12 is connected to valve body A1.

[0027] In this embodiment of the present invention, valve body B2 is slidably inserted into valve body A1, and guide grooves 101 are symmetrically arranged on the outside of valve body A1. Connecting blocks 201 are symmetrically arranged on the outside of valve body B2, and connecting blocks 201 are slidably connected to the guide grooves 101.

[0028] By adopting the above technical solution, during the process of valve body B2 slidingly inserting into valve body A1, connecting block 201 and guide groove 101 slide and cooperate, which plays a guiding role in the insertion and effectively avoids the occurrence of torsion between valve body B2 and valve body A1.

[0029] In this embodiment of the utility model, the rotating ring 11 is rotatably connected to the valve body A1. A guide block 102 is provided on the outside of the valve body A1. An arc-shaped hole 1101 is provided inside the rotating ring 11. The guide block 102 is slidably connected in the arc-shaped hole 1101. A slot 1102 is provided around the outside of the rotating ring 11. The slot 1102 is L-shaped. An inclined surface 11021 is provided inside the slot 1102. The slot 1102 communicates with the guide groove 101. The end of the connecting block 201 is connected in the slot 1102.

[0030] Using the above technical solution, when the connecting block 201 is connected to the guide groove 101, the end of the connecting block 201 is in the slot 1102. Rotating the rotating ring 11 makes the connecting block 201 contact the inclined surface 11021. The rotating ring 11 drives the valve body B2 to move inward, so that the sealing ring A4 is in close contact with the valve body A1 and the valve core 3, and the sealing ring B5 is in close contact with the valve body B2 and the valve core 3, ensuring the sealing performance of the ball valve. When the end of the connecting block 201 moves to the innermost end of the slot 1102, the rotating ring 11 achieves the effect of limiting and fixing the valve body B2.

[0031] In Example 2, based on Example 1, a positioning hole 103 is provided on the outside of the valve body A1, and a screw hole 1103 is provided inside the rotating ring 11. When the connecting block 201 is located at the innermost end of the slot 1102, the positioning hole 103 and the screw hole 1103 are connected. The bolt 12 is threaded into the screw hole 1103, and the end of the bolt 12 is located in the positioning hole 103.

[0032] Using the above technical solution, when the connecting block 201 moves to the innermost end of the slot 1102, the positioning hole 103 and the screw hole 1103 are in a connected state. Rotating the bolt 12 moves the end of the bolt 12 into the positioning hole 103, and the rotating ring 11 is fixed by the bolt 12, thereby ensuring the limiting and fixing effect of the rotating ring 11 on the valve body B2. If it is necessary to separate the valve body A1 and the valve body B2 for maintenance, rotate the bolt 12 in the opposite direction to separate the end of the bolt 12 from the positioning hole 103, and the rotating ring 11 is released from fixation. Rotating the rotating ring 11 in the opposite direction can separate the valve body A1 and the valve body B2. The operation is simple and quick.

[0033] The working principle of this embodiment is as follows: First, valve body B2 is slidably inserted into valve body A1. Connecting block 201 and guide groove 101 slide together, providing a guiding effect and effectively preventing twisting between valve body B2 and valve body A1. After connecting block 201 is connected into guide groove 101, the end of connecting block 201 is in slot 1102. Rotating the rotating ring 11 causes connecting block 201 to contact inclined surface 11021. The rotating ring 11 drives valve body B2 to move inward, making sealing ring A4 and valve body A1 and valve core 3 in close contact, and sealing ring B5 and valve body B2 and valve core 3 in close contact, ensuring the sealing performance of the ball valve. The connecting block 201 moves to the end of slot 1102. When the valve body B2 is at the inner end, the rotating ring 11 serves to limit and fix the valve body B2. After the connecting block 201 moves to the innermost end of the slot 1102, the positioning hole 103 and the screw hole 1103 are connected. Rotating the bolt 12 moves the end of the bolt 12 into the positioning hole 103, and the rotating ring 11 is fixed by the bolt 12, thus ensuring the limiting and fixing effect of the rotating ring 11 on the valve body B2. If it is necessary to separate the valve body A1 and the valve body B2 for maintenance later, rotate the bolt 12 in the opposite direction to separate the end of the bolt 12 from the positioning hole 103, and the rotating ring 11 is released from fixation. Rotating the rotating ring 11 in the opposite direction can separate the valve body A1 and the valve body B2, which is simpler and saves time.
