With its simple structure, compact size, and lightweight design, ball valves are widely used in industries such as petroleum refining, chemical engineering, papermaking, pharmaceuticals, water conservancy, electric power, municipal administration, and steel, playing a vital role in the national economy.

[0003] There are many ball valves for controlling water flow in modern agricultural irrigation. The ball valves on the market are generally controlled by long handles, which are easy to touch by mistake after opening. At the same time, in outdoor agricultural planting environments, unnecessary waste caused by human ignorance of opening the valves often occurs, causing great losses to growers. Utility Model Content

[0004] The purpose of the present utility model is to provide a new ball valve to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A novel ball valve comprises a valve body with a built-in ball valve, a convex control seat arranged on the top of the valve body and a butterfly wing handle detachably connected to the convex control seat; the opening of the ball valve is controlled by a valve stem.

[0007] The convex control seat is fixedly mounted on the valve stem, and as the convex control seat rotates, the valve stem drives the ball valve to rotate together; the convex control seat includes a frustum at the top and a cylinder fixedly arranged below the frustum; a vertically arranged countersunk hole is provided on the inclined surface of the frustum.

[0008] The butterfly handle includes a handle body arranged in the middle and rotors fixedly arranged on both sides of the handle body; the handle body includes an abutment groove arranged at the bottom that matches the conical body and the cylindrical body, and a limiting protrusion arranged in the abutment groove that matches the countersunk hole; when connecting, the limiting protrusion is inserted into the countersunk hole, and the abutment groove abuts against the outer walls of the conical body and the cylindrical body to achieve limited abutment between the butterfly handle and the convex control seat; the cross-section of the rotor is cross-shaped, including a vertically arranged reinforcing rib at the bottom, a first contact block horizontally arranged on the left and right sides, and a second contact block vertically arranged on the top; when in use, the finger contacts the first contact block, which is convenient for exerting downward force to guide the butterfly handle to limit the abutment on the convex control seat; the finger contacts the second contact block, which is convenient for exerting lateral force to guide the butterfly handle to rotate, thereby driving the rotation of the convex control seat.

[0009] Preferably, a guide dome is provided at the top of the limiting protrusion.

[0010] Preferably, an elastic component that can close the countersunk hole is provided in the countersunk hole; the elastic component includes a lightweight spring fixedly built into the countersunk hole and a cover fixedly connected to the lightweight spring; the limiting protrusion and the cover are detachably abutted; the cover slides linearly in the countersunk hole as the spring is stretched and compressed; when the lightweight spring is in a natural rotation state, the upper surface of the cover corresponds to and fits with the inclined surface of the frustum.

[0011] Preferably, a limit block is provided at the mouth of the countersunk hole to limit the cover from protruding beyond the inclined surface of the truncated cone. Correspondingly, the cover is provided with a limit groove matching the limit block. Under the elastic force of the lightweight spring, the limit block and the limit groove are in limited contact with each other.

DETAILED DESCRIPTION

[0019] The following is further described in detail through specific implementation methods:

[0020] Example 1

[0021] like Figure 1-3 As shown, this embodiment shows a new type of ball valve, including a valve body 1 with a built-in ball valve, a convex control seat 3 arranged on the top of the valve body 1, and a butterfly handle 4 that is detachably connected to the convex control seat 3. The opening of the ball valve is controlled by the valve stem 2. The convex control seat 3 is fixedly mounted on the valve stem 2. As the convex control seat 3 rotates, the valve stem 2 drives the ball valve to rotate together. The convex control seat 3 includes a frustum 31 at the top and a cylinder 33 fixedly arranged below the frustum 31. When the ball valve does not need to be adjusted, the butterfly handle 4 is separated from the convex control seat 3. A vertically arranged countersunk hole 32 is provided on the inclined surface of the frustum 31.

[0022] like Figure 2-3As shown, the butterfly handle 4 in this embodiment includes a handle body 41 arranged in the middle and rotors 42 fixedly arranged on both sides of the handle body 41; the handle body 41 includes an abutting groove 411 arranged at the bottom that matches the truncated cone 31 and the cylindrical body 33, and a limiting protrusion 412 arranged in the abutting groove 411 that matches the countersunk hole 32; when connected, the limiting protrusion 412 is inserted into the countersunk hole 32, and the abutting groove 411 abuts against the outer walls of the truncated cone 31 and the cylindrical body 33, realizing The butterfly handle 4 is in limited contact with the convex control seat 3; the cross-section of the rotor 42 is cross-shaped, including a vertically arranged reinforcing rib 421 at the bottom, a first contact block 422 arranged horizontally on the left and right sides, and a vertically arranged second contact block 433 at the top; when in use, the finger contacts the first contact block 422, which is convenient for exerting downward force to guide the butterfly handle 4 to limit and abut against the convex control seat 3; the finger contacts the second contact block 433, which is convenient for exerting lateral force to guide the butterfly handle 4 to rotate, thereby driving the rotation of the convex control seat 3. Specific working instructions: when the ball valve needs to be adjusted, insert the limiting protrusion 412 into the countersunk hole 32, and use your finger to abut the first contact block 422 to cause the abutting groove 411 to abut against the outer walls of the truncated cone 31 and the cylindrical body 33. At this time, your finger abuts the second contact block 433 to realize the clockwise or counterclockwise rotation of the butterfly handle 4, driving the convex control seat 3 connected to its limiting position to rotate together, thereby driving the valve stem 2 to drive the ball valve to rotate together, thereby realizing the adjustment of the ball valve.

[0023] Example 2

[0024] like Figure 1-3 As shown, another embodiment shows a new type of ball valve based on embodiment 1, and the top of the limiting protrusion 412 is provided with a guide dome 413, which facilitates the plug-in connection between the limiting protrusion 412 and the countersunk hole 32, improves the installation efficiency between the butterfly handle 4 and the convex control seat 3, and improves the practicality of the ball valve.

[0025] Example 3

[0026] like Figure 1-4As shown, another embodiment shows a new type of ball valve based on embodiment 1, wherein the counterbore 32 is provided with an elastic component that can close the counterbore 32; the elastic component includes a lightweight spring 321 fixedly built into the counterbore 32 and a sealing cover 322 fixedly connected to the lightweight spring 321; the limiting protrusion 412 is detachably abutted against the sealing cover 322; the sealing cover 322 slides linearly in the counterbore 32 with the extension and compression of the spring; when the lightweight spring 321 is in a natural rotation state, the upper surface of the sealing cover 322 corresponds to and fits with the inclined surface of the frustum 31. Since ball valves are mostly set outdoors in agricultural planting, it is difficult to avoid a large amount of foreign matter from entering the counterbore 32 over time, making it impossible for the butterfly handle 4 to smoothly abut against the convex control seat 3, thereby affecting the normal opening of the ball valve. The sealing cover 322 in the elastic component can effectively avoid the occurrence of this situation, thereby ensuring the normal practical use of the ball valve outdoors.

[0027] It is further explained that in a further feasible embodiment of this embodiment, a limit block is provided at the orifice of the countersunk hole 32 to limit the cover 322 from protruding beyond the inclined surface of the truncated cone 31. Correspondingly, the cover 322 is provided with a limit groove matching the limit block. Under the elastic force of the lightweight spring 321, the limit block and the limit groove are in limited contact with each other, thereby realizing an effective and smooth connection of the cover 322 in the countersunk hole 32, thereby improving the practicality of the ball valve.

[0028] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
