Specific implementation manner

[0024] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0025] Refer to Figures 1-4 , an embodiment provided by the present utility model, a ball valve that is easy to install, includes a valve body 1, a valve seat 4 is fixedly connected above the valve body 1, a valve stem 2 is disposed through the inside of the valve seat 4, a handle 3 is fixedly connected to the upper end of the valve stem 2, first connecting rings 5 are fixedly connected to both ends of the valve body 1, and a second connecting ring 7 is correspondingly disposed at the other end of the first connecting ring 5. By rotating the handle 3, the valve stem 2 can be driven to rotate, so as to drive the sphere inside the valve body 1 to rotate, ensuring the normal operation of the entire valve;

[0026] A connecting pipe 8 is disposed through the interior of the second connecting ring 7. First mounting blocks 6 are fixedly connected to both outer ends of the first connecting ring 5, and second mounting blocks 9 are fixedly connected to both outer ends of the second connecting ring 7. The first mounting blocks 6 and the second mounting blocks 9 correspond to each other. A limiting block 10 is fixedly connected to the outer end of the second mounting block 9, and a slot 18 is formed in the interior of the limiting block 10. A spring 19 is fixedly connected to one inner end of the slot 18, and the other end of the spring 19 is fixedly connected to a limiting plate 17. The spring 19 can ensure that the positioning block 16 has an elastic force, and the other end of the limiting plate 17 is fixedly connected to a positioning block 16. The positioning block 16 is disposed through the interior of the limiting block 10. A limiting groove 11 is formed in the interior of the first mounting block 6. The limiting block 10 corresponds to the limiting groove 11. A positioning groove 12 is formed in the lateral position of the first mounting block 6. The positioning block 16 corresponds to the positioning groove 12. When the connecting pipe 8 is installed on the valve body 1, the pipe connection parts at both ends of the valve body 1 are smaller in diameter than the connecting pipe 8. Therefore, it can be inserted during installation, thereby improving the sealing performance during installation. Press the positioning block 16 on the limiting block 10 inward to make it contract inward. At this time, the staff directly inserts the limiting block 10 into the interior of the limiting groove 11. When the positioning block 16 passes through the position of the positioning groove 12, it can pop out outward through the internal spring 19, thereby realizing the quick snap-fit installation operation of the valve body 1 and the external pipeline;

The first mounting plates 13 and the second mounting plates 14 correspond to each other. Screw holes 15 are formed in the first mounting plates 13 and the second mounting plates 14. The first mounting plates 13 and the second mounting plates 14 are arranged in a cross manner. After corresponding installation, the first mounting plates 13 and the second mounting plates 14 are in contact with each other. The staff can cooperate with the screw holes 15 by screwing bolts to realize the secondary locking of the connection part of the valve body 1, improving the strength and sealing performance of the connection part. The screw holes 15 can be used in cooperation with external bolts and nuts during use, thereby improving the stability during use.

[0028] Working principle: When the device is in use, first, the first connecting ring 5 and the second connecting ring 7 are corresponded, and the positioning block 16 on the limiting block 10 is pressed inward to make it contract inward. At this time, the staff directly inserts the limiting block 10 into the interior of the limiting groove 11. When the positioning block 16 passes through the position of the positioning groove 12, it can pop out outward through the internal spring 19, thereby realizing the quick snap-fit installation operation of the valve body 1 and the external pipeline. After corresponding installation, the first mounting plates 13 and the second mounting plates 14 are in contact with each other. The staff can cooperate with the screw holes 15 by screwing bolts to realize the secondary locking of the connection part of the valve body 1, improving the strength and sealing performance of the connection part.
