[0002] Ball valve, the opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between the V-type ball core and the metal valve seat with hard alloy surfacing, which is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium in the pipeline, but also close any channel to connect the other two channels.

[0003] After searching, the utility model patent with Chinese patent announcement number CN216279494U discloses a ball valve seat that is not easy to deflect, which belongs to the field of ball valves. A ball valve seat that is not easy to deflect includes a valve seat, a ball valve is fixedly connected to the upper end of the valve seat, two expansion screws are threadedly connected to the upper end of the valve seat, the expansion screws are located on the outside of the ball valve, fixing boxes are installed on both sides of the valve seat, a socket is drilled in the fixing box, a screw is slidably connected in the socket, a lower magnet is installed in the screw, a rotating connecting rod is fixedly connected to the right end of the screw, a supporting column is rotatably connected to the right end of the rotating connecting rod, the supporting column is located in the socket, a supporting baffle is fixedly connected to the right end of the support column, a slot is drilled in the fixing box, the slot is located on the upper side of the socket, an upper magnet is slidably connected in the slot, the upper magnet and the lower magnet attract each other, a pressure plate is fixedly connected to the right end of the upper magnet, a pull rod is fixedly connected to the upper end of the upper magnet, and fixing bolts are threadedly connected at both ends of the fixing box, which can reduce the deviation of the ball valve seat caused by water flow erosion and increase the service life of the device.

[0004] After searching the above patent, it was found that the ball valve offset was handled, but the device failed to handle the opening, closing and locking of the inside of the ball valve. When the pipeline is damaged, the ball valve needs to be closed for maintenance. During the maintenance process, other personnel may mistakenly open the ball valve without knowing that the pipeline is damaged, causing liquid to splash out from the damaged part of the pipeline, thereby causing liquid waste, polluting the environment, and easily causing harm to the maintenance workers. Utility Model Content

[0005] The utility model aims to provide a ball valve with a locking mechanism, which can facilitate locking of the ball valve and solve the problem in the prior art that it is inconvenient to lock the ball valve.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] Preferably, a movable plate is slidably connected inside the fixed block, a spring 1 is fixedly connected between the side wall of the movable plate and the inner wall of the fixed block, and the movable plate is fixedly connected with the clamping block through and through.

[0010] Preferably, a slide bar is slidably connected inside the rod body, a second spring is fixedly connected between the lower end of the slide bar and the inner bottom of the rod body, and the end of the block is in contact with the side wall of the slide bar.

[0011] Preferably, two notches are symmetrically arranged on the side wall of the slide bar, the lower end of the notch and the end of the block are both inclined, and the notch matches the block.

[0012] Preferably, two cross bars are symmetrically fixedly connected to the side wall of the sliding rod, a groove is arranged inside the cross plate, and the cross bar is slidably connected to the groove.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] 1. By pressing the two cross bars, the slide bar slides and slides into the groove.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A ball valve with a locking mechanism comprises a valve body 1, a ball 3 is rotatably connected inside the valve body 1, a column 4 is fixedly connected to the upper end of the valve body 1, a rod 7 is rotatably connected inside the column 4, the lower end of the rod 7 is fixedly connected to the upper end of the ball 3, and a horizontal plate 12 is symmetrically fixedly connected to the side wall of the rod 7; two fixed blocks 8 are symmetrically arranged on the side wall of the rod 7, a clamping block 9 is slidably connected inside the fixed block 8, the clamping block 9 is slidably connected to the side wall of the rod 7, a sliding groove 5 is arranged inside the column 4, and the fixed block 8 is connected to the sliding groove 5. The groove 5 is slidably connected, and a plurality of positioning holes 6 are distributed in a circular array on the side wall of the column 4. The positioning hole 6 is communicated with the slide groove 5, and the clamping block 9 is slidably connected with the positioning hole 6. The operator rotates the rod body 7 through the two cross plates 12, so that the rod body 7 drives the ball 3 to rotate inside the valve body 1. When the rod body 7 drives the ball 3 to rotate, the clamping block 9 automatically shrinks to the inside of the fixed block 8. When the ball 3 rotates to open the inside of the valve body 1, the clamping block 9 slides out from the inside of the fixed block 8 to the inside of the corresponding positioning hole 6, thereby limiting and locking the ball 3.

[0023] Both ends of the valve body 1 are fixedly connected with flanges 2, and the side wall of the flange 2 is provided with a plurality of holes in a circular array. A through groove is provided inside the sphere 3, so that the valve body 1 can be easily installed at a designated position by installing the flange 2.

[0024] A movable plate 10 is slidably connected inside the fixed block 8, a spring 11 is fixedly connected between the side wall of the movable plate 10 and the inner wall of the fixed block 8, the movable plate 10 and the clamping block 9 are fixedly connected through, and when the rod body 7 drives the ball 3 to rotate, the pulling force of the spring 11 causes the movable plate 10 to drive the clamping block 9 to retract from the inside of the positioning hole 6 to the inside of the fixed block 8.

[0025] A slide bar 14 is slidably connected inside the rod body 7, and a spring 16 is fixedly connected between the lower end of the slide bar 14 and the bottom of the rod body 7. The end of the block 9 fits against the side wall of the slide bar 14. Through the elasticity of the spring 16, the slide bar 14 automatically slides upward and resets after being pressed.

[0026] Two notches 15 are symmetrically arranged on the side wall of the slide bar 14. The lower end of the notch 15 and the end of the block 9 are both inclined. The notch 15 cooperates with the block 9. When the slide bar 14 is upward, the inclined end of the notch 15 contacts the inclined end of the block 9, so that the block 9 slides out from the inside of the notch 15 and fits with the side wall of the slide bar 14. When the slide bar 14 slides downward, the end of the block 9 slides from the side wall of the slide bar 14 to the inside of the notch 15.

[0027] Two cross bars 17 are symmetrically fixedly connected to the side wall of the slide bar 14. A groove 13 is provided inside the cross plate 12. The cross bars 17 are slidably connected to the groove 13. By pressing the two cross bars 17, the slide bar 14 slides, and the cross bars 17 slide into the groove 13, so that the operator can hold the cross plate 12 to rotate the rod body 7.

[0028] In the utility model, the valve body 1 is installed at a specified position by means of the installed flange 2. When the interior of the valve body 1 needs to be opened, the two cross bars 17 are pressed to slide the slide bar 14, and the cross bar 17 slides into the interior of the groove 13. At the same time, the pulling force of the spring 11 causes the movable plate 10 to drive the block 9 to retract from the interior of the positioning hole 6 to the interior of the fixed block 8. At the same time, the end of the block 9 slides from the side wall of the slide bar 14 to the interior of the slot 15. At this time, the entire valve body 1 is in an unlocked state. Then the operator holds the cross plate 12 to rotate the rod body 7, so that the rod body 7 drives the ball 3 to rotate inside the valve body 1.

[0029] After the inside of the valve body 1 is opened, the elasticity of the spring 2 16 causes the slide rod 14 to automatically slide upward and reset after the pressing force ends, and at the same time, the inclined end of the notch 15 contacts the inclined end of the block 9, causing the block 9 to slide out from the inside of the notch 15 and fit with the side wall of the slide rod 14, and at the same time, the block 9 slides into the inside of the positioning hole 6.
