Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a built-in spherical fully welded ball valve. Background Technology

[0002] Built-in ball valves are a type of valve used in fluid transport systems to cut off, regulate, or divert fluids. Their core feature is the combination of a "built-in ball core" and a "fully welded valve body structure." They are widely used in petroleum, natural gas, chemical, and energy industries, and are especially suitable for high-pressure, low-temperature, corrosive media or long-distance pipelines where sealing, pressure resistance, and safety requirements are extremely high.

[0003] Chinese patent CN216279511U discloses a fully welded ball valve, including a ball valve body with a rotating shaft mounted on it. A square hole is formed at the upper end of the rotating shaft, and a square rod is movably inserted into the square hole. A handle is fixedly connected to the upper end of the square rod. A mounting sleeve is detachably connected to the upper end of the ball valve body, and the mounting sleeve is fitted onto the surface of the handle. An elastic mechanism is provided inside the mounting sleeve and connected to the handle. Ultimately, the handle is reset by the elastic action of a spring, and the square rod disengages from the square hole. This allows the handle to rotate freely when not pressed, thus protecting the ball valve body from accidental opening when not in use and improving its practicality.

[0004] When existing ball valves stop working or are in operation, the opening and closing of the ball valve must be achieved by operating the control valve end. Furthermore, the control valve end must lock the current operating state of the ball valve. After the control valve end is locked, factors such as collisions with external objects or aging of components over long-term use may cause displacement of the control valve end, thereby disrupting the locked operating state of the ball valve. This results in the inability to maintain stable operating parameters, reducing the practicality of the built-in fully welded ball valve. Utility Model Content

[0028] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0029] Example 1

[0030] like Figure 1 - Figure 3 As shown, the present invention proposes a built-in fully welded spherical valve, comprising: a supporting base plate 1, a ball valve body 2, and auxiliary components; the ball valve body 2 is connected to the supporting base plate 1; the auxiliary components are connected to the supporting base plate 1; the auxiliary components include a locking element a and two locking elements b; the locking element a is connected to the supporting base plate 1 and is detachably connected; the two locking elements b are connected to the upper ends of the supporting base plate 1 and are detachably connected; the locking element a includes a support rod 3, a fixing block 301, and a locking plate a302; the upper end of the support rod 3 is connected to the fixing block 301, and the two sides of the fixing block 301 are respectively connected to the locking plates a302 for locking the ball valve body 2; the two locking elements b respectively include an mounting rod 402 and a locking plate b403; the upper end of the mounting rod 402 is connected to the locking plate b403 for locking the ball valve body 2. By using auxiliary components for locking in conjunction with the built-in fully welded ball valve, a dual auxiliary locking system is achieved for the built-in fully welded ball valve. This prevents the ball valve from being affected by external object collisions or aging components, thus improving the stability of the built-in fully welded ball valve. It also prevents the ball valve from being affected by displacement of the control valve end during operation or when the ball valve stops working. This conveniently assists in the use of the built-in fully welded ball valve and enhances its practicality.

[0031] Example 2

[0032] like Figure 1 and Figure 3 As shown, this utility model proposes a built-in spherical fully welded ball valve. Based on the above embodiments, this embodiment also details the specific components of the supporting base plate 1 and the matching method.

[0033] Further explanation: the two locking components b each include an annular sleeve 4, an annular block 401, a mounting bracket 404, a connecting plate 405, and a connecting block 406. The annular sleeve 4 is connected to the outer wall of the annular block 401, which has uniformly distributed through holes. The mounting bracket 404 is connected to the connecting plate 405, which is attached to one side of the annular sleeve 4. The lower end of the mounting bracket 404 is connected to the connecting block 406, which is attached to the support base plate 1. The lower end of the mounting rod 402 has a mounting hole, which is attached to the outer wall of the annular sleeve 4 and to one side of the annular block 401. A pre-drilled threaded hole is provided on one side of the mounting bracket 404. By using flange bolts to thread through the through holes and the pre-drilled threaded hole, the mounting rod 402 and the annular block 401 can be detachably connected.

[0034] To further explain, the support base plate 1 has several reserved mounting holes for detachable connection with auxiliary components and the ball valve body 2; mounting blocks 303 are connected to both sides of the lower end of the support rod 3, and the mounting blocks 303 are connected to the support base plate 1. The mounting blocks 303 and the connecting blocks 406 are respectively provided with reserved connecting holes. The reserved connecting holes and the corresponding reserved mounting holes are aligned, bolts are passed through, and nuts and bolt threads are used to lock them, so that the auxiliary components and the support base plate 1 can be detachably connected. In addition, the bracket at the lower end of the ball valve body 2 can be detachably connected to the support base plate 1 through the cooperation of bolts and nuts. The operation is simple and convenient to use.

[0035] The working principle of this utility model is as follows: The built-in spherical fully welded ball valve is installed on the support base plate 1. The operator installs auxiliary components according to the usage requirements of the built-in spherical fully welded ball valve. The user operates the annular sleeve 4, which is fitted around the ball valve inlet and outlet pipes. The annular sleeve 4 is connected to the mounting bracket 404 via the connecting plate 405. The connecting block 406 at the lower end of the mounting bracket 404 is connected to the support base plate 1, thus supporting the connection between the annular sleeve 4 and the ball valve. The annular sleeve 4 drives the annular block 401 connected to the outer wall. By using a screw that passes through the through hole on the annular block 401 and through the mounting hole and the reserved threaded hole at the lower end of the mounting rod 402, the mounting rod 402 drives the locking plate b403. The locking plate b403 moves to the periphery of the valve end handle on the ball valve inlet and outlet pipes. After the movement is complete, align the reserved connection holes on the connecting block 406 with the corresponding reserved mounting holes, and use bolts and nuts to ensure that the two locking parts b are assembled in the same way, so as to achieve the cooperation between the inlet and outlet valve ends of the ball valve; the support rod 3 drives the fixing block 301, the fixing block 301 drives the locking plate a302, and the locking plate a302 is connected to the outer wall of the ball valve control end, so as to lock the ball valve control end. The lower end of the support rod 3 is connected to the support base plate 1 through the mounting block 303, so that the reserved connection holes on the mounting block 303 are aligned with the corresponding reserved mounting holes, and the assembly is carried out using bolts and nuts. The operation is simple and easy to use. The convenient auxiliary components are used in conjunction with the built-in ball valve to improve the working stability of the built-in ball valve.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
