Description

Technical Field

[0001] The utility model relates to the technical field of long-handle locking ball valves, in particular to a long-handle internal-thread magnetic locking ball valve. Background Art

[0002] The core component of a ball valve is a spherical closing member, usually made of stainless steel or other corrosion-resistant materials. The ball has a straight-through hole. When the ball hole is aligned with the pipe, the fluid can pass freely; when the ball is rotated 90 degrees, the ball hole is offset from the pipe, and the fluid flow is cut off. There is a ball valve adapted for a long-handle structure. The main difference between it and an ordinary ball valve is the length of the handle. The long handle design makes it easier to operate, especially when space is limited or long-distance operation is required. The long handle design makes it easier for the operator to apply torque to open or close the valve, which is particularly suitable for large valves or high-pressure environments. The handle of a traditional locking ball valve is connected to the key, and there is a certain gap when it contacts the valve stem of the opening and closing component of the ball valve. The gap needs to be overcome when opening, which will affect the stability of the ball valve, resulting in insufficient stability of the ball valve and poor locking effect of the ball valve.

[0003] For example, patent publication number CN201916571U discloses a globe valve with a magnetic locking function. It includes a valve body and a valve core disposed within the body. The valve core is characterized by a magnetic locking valve core with a plurality of pin holes formed on the surface of the housing, which are filled with compression springs and magnetic pellets. The valve core stem is rotatably connected to the valve cap, and the key to the magnetic locking valve core is a magnetic wrench that matches the shape of the valve cap. Utility Model Content

[0004] Technical problems to be solved by utility models

[0005] In response to the technical problem that the existing handle is connected to the key, there is a certain gap when it contacts the valve stem of the opening and closing component of the ball valve, resulting in poor stability and locking effect, the utility model provides a long-handled internal thread magnetic locking ball valve, whose handle and valve stem fit tightly with no gap, thereby improving stability and locking effect.

[0006] Technical Solution

[0007] In order to solve the above problems, the technical solution provided by the present invention is as follows:

[0008] A long-handled internal-thread magnetic locking ball valve comprises a valve body, a valve core, a valve stem, a handle and a key. The valve stem is provided at the control port of the valve body. The control port is provided with a blind hole 1. A magnet 1 is slidably connected to the blind hole 1. The magnet 1 is elastically connected to the bottom of the blind hole 1. A lock cover is provided above the control port. A blind hole 2 adapted to the magnet 1 is provided below the lock cover. The length of the magnet 1 is less than the depth of the blind hole 1 and greater than the depth of the blind hole 2. The key can movably cover the lock cover. The key is provided with magnet 2 for repelling the magnet from moving downward. The end of the valve stem is fixedly connected to the handle.

[0009] The valve body is the main body of the valve, with internal flow channels for controlling fluid flow. The valve core is a spherical closing element with a straight-through hole inside, which controls the flow of fluid. The valve stem is the transmission component that connects the valve core and the handle, transmitting the handle's operating torque. The long handle design facilitates the operator's application of torque to open and close the valve. The handle is fixed to the valve stem, ensuring no gap between them. The handle and valve stem fit tightly together, ensuring no gap, improving valve stability and operational precision. The key is used to unlock and lock the valve and contains two magnets. The control port structure consists of a blind hole 1 located within the control port of the valve body, which accommodates magnet 1. Magnet 1 is located within blind hole 1 and connected to the bottom of blind hole 1 via an elastic element (such as a spring), allowing it to move up and down within blind hole 1. The locking cover covers the control port and contains a blind hole 2 to accommodate magnet 2. The length of the first magnet is less than the depth of the first blind hole and greater than the depth of the second blind hole. The first magnet moves upward and can be stuck between the first and second blind holes to lock the valve stem. The second magnet is set inside the key to repel the downward movement of the magnet to achieve the unlocking function.

[0010] Optionally, the handle is provided with an upward bend.

[0011] The upward bend design makes it easier for the operator to apply torque, especially when space is limited or long-distance operation is required. The bend design is ergonomic, reducing operator fatigue and improving operating comfort.

[0012] Optionally, the end of the valve stem is provided with a thread, the end of the handle is provided with a round hole that matches the valve stem, the valve stem fits tightly with the handle, and the end of the valve stem is fastened with a nut.

[0013] Threaded connection: The end of the valve stem is provided with a thread, and the end of the handle is provided with a round hole that matches the valve stem. Nut fastening: The valve stem and the handle are tightly fitted together by the nut, ensuring that there is no gap between the two, which improves the stability and accuracy of the operation.

[0014] Optionally, the first magnetic steel and the second magnetic steel are positioned correspondingly in the axial direction of the valve stem.

[0015] Axial alignment: Magnets 1 and 2 are aligned axially on the valve stem, ensuring the magnetic field generated by Magnet 2 directly impacts Magnet 1, improving locking and unlocking reliability. Blind hole 2 beneath the lock cover is precisely aligned with blind hole 1 in the valve body control port, ensuring axial alignment of Magnets 1 and 2.

[0016] Optionally, there are multiple magnetic steels 1 and 2.

[0017] Multiple first magnets are installed within blind hole one, each connected to the bottom of blind hole one via an elastic element. Multiple second magnets are installed within the key, with the number of first magnets matching that of the first magnets, ensuring that each second magnet corresponds to a first magnet. Each first and second magnet are positioned axially with respect to the valve stem, ensuring that the magnetic field generated by the second magnet directly affects the first magnet. Increasing the number of magnets improves locking reliability.

[0018] Optionally, a side wall extending downward is provided around the periphery of the locking cover, and the locking cover is adapted to the control port.

[0019] Side wall design: The periphery of the lock cover is provided with a downward extending side wall, which fits tightly with the edge of the control port, thereby improving the sealing between the lock cover and the control port.

[0020] Adaptability: The shape and size of the lock cover are compatible with the control port to ensure accuracy and stability during installation.

[0021] Optionally, a retaining spring is provided between the side wall and the control port.

[0022] The clamping spring is arranged between the side wall of the lock cover and the control port, and is used to enhance the connection strength and sealing performance between the lock cover and the control port.

[0023] Optionally, a flexible sheath is provided outside the handle.

[0024] The flexible sheath covers the outside of the handle to protect the handle from the influence of the external environment, while improving the operator's grip comfort and reducing hand fatigue.

[0033] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0034] Example

[0035] Combined with attachment Figure 1-4 A long-handled, internally threaded magnetic locking ball valve comprises a valve body 1, a valve core 2, a valve stem 3, a handle 9, and a key 11. In this embodiment, a hard seal is incorporated into the valve core 2 and the valve body 1, allowing torque to be applied to open or close the valve. The valve stem 3 is connected to the valve core 2 and is equipped with multiple sealing rings around its periphery, sealingly connecting to the inner wall of the control port 12 of the valve body 1.

[0036] A valve stem 3 is provided at the control port 12 of the valve body 1. The control port 12 is provided with a blind hole 13. A magnet 5 is slidably connected to the blind hole 13. The magnet 5 is elastically connected to the bottom of the blind hole 13 by a spring 4. A lock cover 8 is provided above the control port 12. A blind hole 2 14 adapted to the magnet 1 5 is provided below the lock cover 8. The length of the magnet 1 5 is less than the depth of the blind hole 13 and greater than the depth of the blind hole 2 14. The key 11 can movably cover the lock cover 8. The key 11 is provided with a magnet 2 10 for repelling the downward movement of the magnet 1 5. The end of the valve stem 3 is fixedly connected to the handle 9.

[0037] The handle 9 features an upward bend at both ends, forming an obtuse angle to prevent interference with surrounding equipment during operation, making it suitable for use in confined spaces or when remote operation is required. This effectively prevents theft while ensuring maximum opening torque. The handle 9 is detached from the key 11 and securely connected to the valve stem 3, ensuring a more stable opening process.

[0038] The end of the valve stem 3 is provided with a thread, and the end of the handle 9 is provided with a circular hole that matches the valve stem 3. The valve stem 3 fits tightly with the handle 9, and the end of the valve stem 3 is fastened with a nut 15. The lower end of the nut 15 abuts against the upper end of the edge of the circular hole and limits the position.

[0039] The first magnet 5 and the second magnet 10 are located in corresponding positions in the axial direction of the valve stem 3. There are multiple magnets 1 and 2.

[0040] The periphery of the lock cover 8 is provided with a side wall extending downwards, and the lock cover 8 is adapted to the control opening 12. A clamping spring 6 is provided between the side wall and the control opening 12.

[0041] A flexible sheath is provided on the outside of the handle 9. The flexible sheath is made of rubber, plastic or other soft materials and has good wear resistance and aging resistance.

[0042] Installation method:

[0043] Step 1: Install the positioning piece 7 on the valve stem 3 in a counterclockwise direction according to the corresponding flat square;

[0044] Step 2: Place the spring 4 and magnet 5 into the hole of the valve body 1 in order from bottom to top;

[0045] Step 3: Install the lock cover 8 on the valve stem 3 and fasten it with the circlip 6;

[0046] Step 4: Install the handle 9 on the valve stem 3 and lock it;

[0047] Step 5: Install the magnet 10 into the key 11 and place it on the handle 9 of the ball valve to open and close the ball valve freely.

[0048] Unlocking process:

[0049] Combined with attachment Figure 1, place the key 11 on top of the lock cover 8, and align the second magnetic steel 10 in the key 11 with the second blind hole 14 in the lock cover 8.

[0050] The magnetic field generated by the second magnet 10 repels and drives the first magnet 5 downward, overcoming the elastic force of the elastic element, so that the first magnet 5 approaches the bottom of the blind hole 13.

[0051] When the magnet 1 5 moves down to a position completely out of the blind hole 2 14 , the handle 9 can rotate freely to open and close the valve.

[0052] Locking process:

[0053] Combined with attachment Figure 2 , remove the key 11, and the magnet 10 no longer generates a repulsive force.

[0054] Under the action of the elastic element, the magnet 1 5 returns to the blind hole 2 14 and blocks the blind hole 13 and the blind hole 2 14, relocking the handle 9 so that the handle 9 cannot rotate and the valve returns to the locked state.

[0055] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
