DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , an embodiment provided by the utility model:

[0025] A ball valve that is easy to disassemble and assemble a ball, comprising:

[0026] The main body comprises a first valve body 1, a second valve body 11 is installed on the surface of the first valve body 1, a third valve body 12 is connected to the surfaces of the first valve body 1 and the second valve body 11 through a bolt assembly, a ball body 13 is arranged on the inner surface of the first valve body 1, a valve stem 14 is fixedly connected to the surface of the ball body 13, and a rotating handle 15 is fixedly connected to the surface of the valve stem 14. When the ball valve is used, the first valve body 1 and the third valve body 12 are respectively connected to the pipeline, and the rotation of the rotating handle 15 drives the rotation of the valve stem 14 and the ball body 13, thereby realizing the control and regulation of the fluid in the pipeline;

[0027] The splitting mechanism includes a mounting block 2, which is fixedly connected to the surface of the second valve body 11. A mounting hole 21 and a groove 22 are provided inside the mounting block 2. A through hole 23 is provided inside the second valve body 11. A long screw 24 is fixedly connected to the inner surface of the first valve body 1. A nut 25 is installed on the surface of the long screw 24. A sealing strip 26 is provided on the surface of the first valve body 1. A connecting groove 27 is provided on the inner surface of the second valve body 11. Under the action of the mounting block 2, the nut 25 is installed, so that the nut 25 is more tightly and firmly connected to the surface of the ball valve when connected to the long screw 24, thereby avoiding the situation where gaps cause water seepage.

[0028] Furthermore, two groups of mounting blocks 2 are provided, and the two groups of mounting blocks 2 are installed on both sides of the second valve body 11. The diameter of the mounting hole 21 is the same as the diameter of the through hole 23, and the diameter of the groove 22 is larger than the diameter of the mounting hole 21. Two groups of through holes 23 and long screws 24 are provided. Under the action of the mounting hole 21 and the through hole 23, the long screw 24 can be installed, and the nut 25 can be installed through the groove 22.

[0029] Furthermore, two groups of through holes 23 are opened on both sides of the second valve body 11, and two groups of long screws 24 are installed on both sides of the first valve body 1. The long screws 24 are plugged and connected to the surfaces of the through holes 23 and the mounting holes 21. The nuts 25 are threadedly connected to the surfaces of the long screws 24, and the nuts 25 are abutted and connected to the surface of the grooves 22. Under the connection between the long screws 24 and the nuts 25, the side of the split second valve body 11 away from the third valve body 12 is fixed and limited, while the side close to the third valve body 12 is connected and fixed by the original bolt assembly.

[0030] Furthermore, the cross-section of the sealing strip 26 is "U"-shaped, and both sides of the sealing strip 26 are snap-connected to the surface of the connecting groove 27. The cross-section of the connecting groove 27 is "L"-shaped, and two groups of connecting grooves 27 are provided. One group of connecting grooves 27 is opened on the surface of the first valve body 1, and the other group of connecting grooves 27 is opened on the surface of the second valve body 11. The sealing strip 26 is made of rubber material. Under the connection between the sealing strip 26 and the connecting groove 27, the connection between the first valve body 1 and the second valve body 11 is sealed to prevent water seepage, and when installing the sealing strip 26, one side is first installed on the connecting groove 27 of the first valve body 1 by extrusion, and when the second valve body 11 is installed, the other side of the sealing strip 26 is snap-connected with the connecting groove 27 of the second valve body 11 by extrusion.

[0031] Furthermore, an extension mechanism is provided on the surface of the rotating handle 15, and the extension mechanism includes an extension handle 3, which is slidably connected to the surface of the rotating handle 15, and a movable groove 31 is opened on the surface of the extension handle 3. A short screw 32 is fixedly connected to the surface of the rotating handle 15, and a baffle 33 is fixedly connected to the surface of the short screw 32. A fastening block 34 is installed on the surface of the short screw 32. Under the action of the extension handle 3, the length of the rotating handle 15 is extended, and then the force arm is increased when the rotating handle 15 is rotated, making it more labor-saving to rotate the spherical body 13.

[0032] Furthermore, the extension handle 3 is slidably connected to the surface of the short screw 32 through a movable groove 31. The length of the movable groove 31 is smaller than the length of the extension handle 3. One end of the short screw 32 is fixedly connected to the surface of the rotating handle 15, and the other end of the short screw 32 is fixedly connected to the surface of the baffle 33. When the extension handle 3 slides on the rotating handle 15, the movable groove 31 can slide on the surface of the short screw 32, and the short screw 32 passes through the surface of the extension handle 3 through the movable groove 31.

[0033] Furthermore, the fastening block 34 is connected to the surface of the short screw 32 by a thread, and the fastening block 34 is abutted against the surface of the extension handle 3. The size of the baffle 33 is larger than the size of the short screw 32, and the internal thread size of the fastening block 34 is smaller than the size of the baffle 33. Under the connection between the short screw 32 and the fastening block 34, the extended handle 3 is limited and fixed after movement. In addition, the surface of the fastening block 34 is provided with anti-slip strips distributed in a ring array on the surface of the fastening block 34, which can make the rotation of the fastening block 34 more labor-saving. At the same time, the baffle 33 can limit the fastening block 34 to prevent it from falling off the short screw 32 when not in use.

[0034] Working principle: Before removing the ball body 13, first remove the nut 25 from the long screw 24 through the thread so that it no longer rests on the surface of the groove 22, and remove the bolt assembly between the second valve body 11 and the third valve body 12 through the thread. At this time, pull the second valve body 11 to move it out along the direction of the long screw 24, and the long screw 24 and the mounting hole 21, the through hole 23 are canceled from the plug-in state, and the sealing strip 26 and the connecting groove 27 are also canceled from the clamping state, and then the ball body 13, the valve stem 14 and the rotating handle 15 are removed as a whole for replacement.

[0035] Before using the rotating handle 15, press your hand on the fastening block 34 and the anti-slip strip, and rotate the fastening block 34 through the thread to cancel the engagement with the extension handle 3, and limit the fastening block 34 under the action of the baffle 33. At this time, move the extension handle 3 to make it slide on the surface of the rotating handle 15, and the moving groove 31 also slides on the surface of the short screw 32. After moving to the desired position, rotate the fastening block 34 again through the thread to make it engage with the extension handle 3 again, so as to complete the limitation of the moved extension handle 3, so that the force arm for operating the rotating handle 15 is increased.
