Description

Technical Field

[0001] This utility model relates to the field of ball valves, and in particular to a full-flow drain ball valve with bypass. Background Technology

[0002] The drain ball valve is a common type of valve that uses the rotation of a ball to achieve its switching function. It features simple structure, good sealing performance, and convenient operation.

[0003] When using a common drain ball valve, the valve handle is rotated, which drives the valve stem and the valve ball to rotate, thus achieving the opening and closing function. However, the valve handle is usually exposed and is easily affected by external impacts, which can cause the valve to be accidentally activated, affecting the safety of the ball valve. Utility Model Content

[0004] The purpose of this invention is to provide a full-flow drain ball valve with bypass to solve the problems mentioned in the background art.

[0016] The second bypass interface is fixedly connected to the top of the second connecting pipe.

[0017] Preferably, the positioning structure includes:

[0018] A limiting block is provided at one end of the valve handle. The limiting block is U-shaped, and one end of the valve handle is located in the inner cavity of the limiting block.

[0019] A movable ring, which is rotatably connected to the top of the ball valve body;

[0020] A through groove is provided on the ball valve body, and the through groove is slidably intersected with the movable ring.

[0021] Preferably, the positioning structure further includes:

[0028] The technical effects and advantages of this utility model are as follows:

[0029] This invention utilizes a combination of a first bypass interface, a second bypass interface, a limiting block, a movable ring, a movable groove, a positioning block, and a connecting groove. By changing the position of the bypass interface relative to both ends of the ball valve body, the on / off control of the ball valve body over the bypass interface is altered, improving the practicality of the ball valve. Furthermore, by moving the movable ring upwards, the limiting block moves along with it. The positioning block moves vertically upwards within one of the movable grooves, moving to one end of the connecting groove and releasing the limiting effect on the movable ring. Then, rotating the valve handle causes the movable ring and the limiting block to rotate, and the positioning block slides along the inner cavity of the connecting groove. The limiting block further restricts the valve handle, preventing accidental activation and improving valve safety. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This utility model provides, for example Figure 1-4 The illustrated full-flow drain ball valve with bypass includes a ball valve body 1, a valve handle 2, a connecting structure 3, and a positioning structure 4. The valve handle 2 is mounted on the ball valve body 1 and is used to rotate the valve ball 5 and valve stem 6 to regulate the flow of the ball valve body 1. The connecting structure 3 is mounted on the ball valve body 1 and is used to form a multi-flow structure on the ball valve body 1, thereby forming a bypass pipeline structure on the ball valve body 1. The positioning structure 4 is mounted on the ball valve body 1 and is used to limit and fix the valve handle 2, preventing accidental activation of the valve handle 2.

[0037] Example 1: The connecting structure 3 includes a first connecting pipe 31, which is disposed at one end of the ball valve body 1. The first connecting pipe 31 is straight and fixedly installed on the ball valve body 1 to fix the first bypass interface 32. The first bypass interface 32 is fixedly connected to the top of the first connecting pipe 31 and is disposed at one end of the ball valve body 1 to divert the flow of the first connecting pipe 31. The opening and closing of the ball valve body 1 will not affect the flow of the first bypass interface 32. The plug cap 33 is disposed at the other end of the ball valve body 1 and is sleeved on the ball valve body 1 to close the other end of the ball valve body 1.

[0038] Example 2: The connecting structure 3 includes a second connecting pipe 311, which is located at one end of the ball valve body 1. The second connecting pipe 311 is V-shaped and is used to connect to an external pipe. A second bypass interface 321 is fixedly connected to the top of the second connecting pipe 311 and is located at the other end of the ball valve body 1. When the ball valve body 1 is closed, the second bypass interface 321 is closed.

[0039] The positioning structure 4 includes a limiting block 41, which is located at one end of the valve handle 2. The limiting block 41 is U-shaped, and one end of the valve handle 2 is located inside the limiting block 41. By blocking the rotation of the valve handle 2, the limiting block 41 prevents accidental contact of the valve handle 2 and improves the safety of the ball valve body 1. A movable ring 42 is rotatably connected to the top of the ball valve body 1. One side of the upper surface of the movable ring 42 is fixedly connected to the bottom end of the limiting block 41. The movable ring 42 rotates and moves vertically on the ball valve body 1. The ball valve body 1 has a through groove 43, which is slidably inserted into the movable ring 42 and is used for the movement of the movable ring 42. A positioning block 44 is fixedly connected to one side of the inner wall of the movable ring 42 and moves with the movable ring 42 to limit and fix the limit block 41 and the movable ring 42. A movable groove 45 is located on the outer wall of the ball valve body 1 and is vertically arranged. The movable groove 45 is perpendicular to the positioning block 44. The two movable slots 45 are arranged at right angles to each other, allowing for the vertical movement of the positioning block 44. A connecting slot 46 is formed on the ball valve body 1, with both ends connected to the movable slots 45. The connecting slot 46 is horizontally positioned, forming a U-shaped structure between the movable slots 45 and the connecting slot 46. The connecting slot 46 is used for the rotation of the positioning block 44, which is made of elastic material. The connecting slot 46 is an arc-shaped groove. By moving the movable ring 42 upwards, the limiting block 41 moves along with the positioning block 44. As the movable ring 42 moves vertically upward within the inner cavity of one of the movable slots 45, the positioning block 44 moves to one end of the connecting slot 46, releasing the restriction on the movable ring 42. Then, the valve handle 2 is rotated, causing the movable ring 42 and the limiting block 41 to rotate. The positioning block 44 slides along the inner cavity of the connecting slot 46 to the position of the other movable slot 45. Then, the movable ring 42 moves downward, causing the positioning block 44 to enter the other movable slot 45, preventing the movable ring 42 and the limiting block 41 from rotating and thus limiting and fixing the valve handle 2.

[0040] A ball 5 is installed inside the ball valve body 1. The ball 5 moves within the ball valve body 1 to control the opening and closing of the ball valve body 1. A valve stem 6 is installed on the ball valve body 1. The valve stem 6 is used to connect the valve handle 2 and the ball 5, so that the valve handle 2 drives the valve stem 6 and the ball 5 to rotate together. A water flow hole is opened on the ball 5. A nut 7 is threadedly connected to the top of the ball valve body 1. The nut 7 is used to limit the valve handle 2. Sealing seats 8 are provided on both sides of the ball 5. The sealing seats 8 are made of elastic material to ensure the sealing of the outer side of the ball 5.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
