The inner diameter of the connecting passage 21, the inner diameter of the through hole 411, the inner diameter of the sleeve 42 and the inner diameter of the opening of the valve element 3 are equal. The valve seat 4 tightly wraps the valve core 3 in all directions, and the sealing performance and the stability of the ball valve are effectively improved.

The working principle is as follows:

firstly, the sliding sleeve 64 penetrates through a round hole along the middle part of the inclined plate 62 by a bolt, then the handle 63 is held to rotate the valve rod 5 until the handle 63 rotates to a target position, then the bolt is taken down, the sliding sleeve 64 freely slides down, and the inserting plate 65 is clamped into the inserting groove 81 to complete positioning.

Example two:

the difference from the first embodiment is only that the structure for positioning the sliding sleeve 64 is different. Referring to fig. 5, the middle portions of the sliding sleeve 64 and the inclined plate 62 are not provided with circular holes for bolts to pass through, and a gap 641 is provided in the middle portion of the side of the sliding sleeve 64 opposite to the valve body 1, and the gap 641 penetrates through the sliding sleeve 64 along the inclined direction of the inclined plate 62.

Referring to fig. 6 and 7, a rotation hole 621 is formed through the middle portion of the inclined plate 62, and a positioning rod 66 is disposed in the rotation hole 621, so that the positioning rod 66 can rotate in the axial direction thereof.

Referring to fig. 5 and 6, a positioning bar 661 is fixedly connected to the upper end of the positioning bar 66, and the width of the gap 641 is greater than the width of the positioning bar 661 and less than the length of the positioning bar 661.

Referring to fig. 8 and 9, a driving gear 662 is fixedly sleeved in the middle of the driving rod, and one side of the driving gear 662 is engaged with the driving rack 67. The rotation hole 621 is communicated with a gear chamber 622 in which the drive gear 662 is placed and rotated, and one side of the gear chamber 622 is communicated with a slide chamber 623 in which the drive rack 67 is placed and slid. The driving rack 67 slides along the sliding cavity 623, so that the driving gear 662 can be driven to rotate, and the positioning strip 661 can be driven to rotate. A spring 68 is fixedly connected between one end of the driving rack 67 and the inner wall of the sliding chamber 623. The spring 68 always pushes the rack 67 all the way through the sliding movement in the sliding chamber 623.

When the sliding sleeve 64 is located on the upper side of the positioning strip 661, the positioning strip 661 is rotated to the length direction thereof to be transversely arranged along the inclined plate 62, that is, in the state shown in fig. 5, at this time, the sliding sleeve 64 is limited by the positioning strip 661 and cannot slide off, and the lower end of the inserting plate 65 is higher than the positioning seat 8. Referring to fig. 9, at this time, there is a gap 641 between the driving rack 67 and the inner wall of the end of the sliding cavity 623 far away from the spring 68, but the positioning bar 661 cannot rotate due to the gravity of the sliding sleeve 64, so that the driving rack 67 cannot move forward due to the thrust of the spring 68.

After the sliding sleeve 64 is lifted upwards, the positioning bar 661 can rotate without the gravity action of the sliding sleeve 64, so that the driving rack 67 is pushed by the spring 68 to move forwards to fit the inner wall of the sliding cavity 623, the section of the driving rack 67 moves to drive the driving gear 662 to rotate 90 degrees, and when the positioning cylinder rotates to the length direction and is arranged along the inclined direction of the inclined plate 62, namely the state shown in fig. 10, the sliding sleeve 64 can slide down and the positioning bar 661 passes through the gap 641.

Referring to fig. 5, the four corners of the positioning seat 8 are fixedly connected with connecting rods 9, and the upper ends of the connecting rods 9 extend out relative to the positioning seat 8. One side of the upper end of the connecting rod 9, which faces away from the valve rod 5, is fixedly connected with a top rod 91, the top rod 91 is perpendicular to the axial lead of the connecting rod 9, and one end of the top rod 91, which is far away from the connecting rod 9, is hemispherical.

Referring to fig. 10 and 11, when the ball valve is switched, the handle 6390 degrees is rotated. When the handle 63 passes through the connecting rod 9, the side edge of the inserting plate 65 contacts with the hemispherical head part of the push rod 91 firstly, the push rod 91 pushes the inserting plate 65 upwards and towards the direction departing from the valve rod 5 after the inserting plate is continuously rotated until the inserting plate is pushed to the farthest position when rotating for 45 degrees, at this moment, the positioning strip 661 can rotate for 90 degrees without the gravity action of the sliding sleeve 64, then the handle 63 is continuously rotated, the inserting plate 65 gradually moves downwards and moves towards the valve rod 5 to abut against the positioning seat 8, and finally, the handle 63 is continuously rotated until the inserting plate 65 is clamped into the slot 81, so that the positioning is completed.

In another embodiment, the connecting rod 9 and the positioning seat 8 can be inserted, and the cross section of the connecting rod 9 is square. When the connecting rod 9 is inserted to the side of the jack 91, which is located on the side of the connecting rod 9 opposite to the valve rod 5, the jack 91 can function to jack the insert plate 65. When the connecting rod 9 is inserted to the side of the ejector rod 91, which is positioned on the side of the connecting rod 9 facing the valve rod 5, the ejector rod 91 cannot contact the inserting plate 65, and the rotation of the handle 63 is not influenced.

The working principle is as follows:

firstly, the sliding sleeve 64 is slid to the upper side of the positioning strip 661, then the positioning strip 66190 degrees is rotated by overcoming the acting force of the spring 68, then the sliding sleeve 64 is moved downwards to be attached to the positioning strip 661, and finally the handle 63 is held and rotated 90 degrees. In the rotating process, the inserting plate 65 is firstly jacked up by the jacking rod 91, the sliding sleeve 64 does not limit the positioning strip 661, the driving rack 67 slides under the action of the spring 68, the driving gear 662 is further driven to rotate, the positioning strip 661 rotates for 90 degrees, the sliding sleeve 64 can freely slide, and the inserting plate 65 is clamped into the inserting groove 81 when the rotation is completed.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
