Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a multi-directional regulating ball valve with a valve stem. Background Art

[0002] The working principle of the ball valve is to drive the rotation of the ball through the rotation of the valve stem, thereby realizing the opening and closing of the valve. The opening and closing action of the ball valve only requires a 90-degree rotation, and the operating torque is small, so the opening and closing are quick and easy. In the fully open state, the medium channel is straight-through, so the fluid resistance is relatively small.

[0003] When the ball valve of the prior art is installed in some narrow space positions, if there is an obstruction above the valve stem, it will be very inconvenient during operation. Due to the obstruction of the obstruction, the valve stem is not easy to rotate, which makes it inconvenient to control the pipeline flow. Usually, the valve stem of the ball valve is a straight rod design, which is easily affected by the obstruction, affecting the user experience. In view of the shortcomings of the prior art, the utility model provides a valve stem multi-directional adjustable ball valve to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] The embodiment of the present application provides a multi-directional adjustable ball valve with a valve stem, which solves the problem that when the ball valve of the prior art is installed in some narrow spaces, if there is an obstruction above the valve stem, it will be very inconvenient to operate. Due to the obstruction of the obstruction, the valve stem is not easy to rotate, which makes it difficult to control the pipeline flow. Usually, the valve stem of the ball valve is a straight rod design, which is easily affected by obstruction, affecting the user experience.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] The utility model discloses a multi-directional regulating ball valve with a valve stem. Figure 1-5 As shown, the ball valve comprises a main body 1, a main valve stem 2 is provided on the main valve stem 2, a coupling 3 is connected to the main valve stem 2, and a driven valve stem 4 is connected to the coupling 3;

[0026] The coupling 3 includes a first shaft seat 301 fixedly connected to the main valve stem 2 and a second shaft seat 303 fixedly connected to the driven valve stem 4. An intermediate body 302 is connected between the first shaft seat 301 and the second shaft seat 303. The intermediate body 302 is provided with a first shaft body 3021 and a second shaft body 3022. The first shaft body 3021 is rotatably connected to the first shaft seat 301, and the second shaft body 3022 is rotatably connected to the second shaft seat 303.

[0027] Through the design of the coupling 3, when the driven valve stem 4 rotates, the driven valve stem 4 conveniently drives the coupling 3 to rotate, and then drives the main valve stem 2 to rotate through the coupling 3. As a result, the valve stem of the entire ball valve has a directional rotation mode, which is suitable for ball valves in special spatial positions to ensure easy operation of the ball valve.

[0028] The coupling 3 has a simple structure. When the driven valve stem 4 rotates, it drives the second shaft seat 303, the second shaft body 3022, the intermediate body 302, the first shaft body 3021, the first shaft seat 301 and the main valve stem 2 to rotate in sequence.

[0029] The main valve stem 2 is provided with a first limiting plate 5 and a second limiting plate 6, which are rotatably connected to each other and divide the main valve stem 2 into two parts, an upper part and an lower part. The first limiting plate 5 is provided with a plurality of lock holes 501, and the second limiting plate 6 is provided with a locking mechanism 7. The locking mechanism 7 includes a locking mechanism 7 fixedly connected to the second limiting plate 6 and a movable plug rod 702 movably connected to the inside of the locking mechanism 7. The movable plug rod 702 is movably inserted into the lock hole 501. A stopper 703 is fixedly connected to the movable plug rod 702, and the stopper 703 is slidably connected to the sleeve 701. A spring 704 is fixedly connected to the inside of the stopper 703 and the sleeve 701.

[0030] The device is designed with a first limiting plate 5, a second limiting plate 6 and a locking mechanism 7, so that the first limiting plate 5 and the second limiting plate 6 can be easily rotated and adjusted, thereby adjusting the position of the driven valve stem 4, so that the driven valve stem 4 can be easily installed in multiple positions;

[0031] When rotating the second limit plate 6, first pull the movable rod 702 to make the movable rod 702 disengage from the lock hole 501. At the same time, the movable rod 702 drives the block 703 to move and squeezes the spring 704. At this time, rotate the first limit plate 5 and the second limit plate 6, adjust the direction of the coupling 3 and the driven valve stem 4. After adjustment, release the movable rod 702, use the spring 704 to reset and push the block 703 and the movable rod 702 to move, so that the movable rod 702 can be inserted into the lock hole 501.

[0032] A support frame 402 is provided on the second limiting plate 6. The support frame 402 is used to support and limit the driven valve stem 4. A rotating handle 401 is fixedly connected to the driven valve stem 4. The setting of the rotating handle 401 makes it easy and labor-saving to rotate the driven valve stem 4.
