Technical Field

[0001] This invention belongs to the field of pipeline sewage technology, specifically relating to a ball valve sewage discharge tool and its manufacturing method. Background Technology

[0002] During the use of natural gas gathering and transmission stations and long-distance natural gas pipelines, it is necessary to regularly inject cleaning fluid into the ball valves installed on them to drain and maintain the valves, ensuring they are in good working condition. However, in recent years, due to the increased demand for natural gas, the pressure to ensure supply in winter has risen. As a result, liquid accumulates in the valve chambers of natural gas pipeline ball valves, and the amount accumulates. The current method of handling this is manual drainage. During manual drainage, there is a problem of liquid splashing. This splashed liquid can contaminate nearby equipment, the ground, and personnel clothing, creating a risk of solid waste. In addition, if the valve opening is not properly controlled during manual drainage, it can cause a large amount of natural gas leakage, which can easily lead to personnel asphyxiation and cause fires and explosions. Summary of the Invention

[0003] The purpose of this invention is to provide a ball valve draining tool and manufacturing method to solve the technical defects of the prior art caused by liquid splashing and natural gas leakage due to manual draining, which can lead to fires and explosions.

[0004] To achieve the above objectives, the present invention employs the following technical solution: Firstly, a ball valve draining tool is provided, including: A clamping device is installed on a pipe stopcock, and the clamping device is provided with a sewage guide device, which is used to connect to the sewage outlet of the pipe stopcock. A liquid flow diversion device, one end of which is connected to a sewage diversion device, and the other end of which is connected to a liquid diversion device, wherein the end of the liquid diversion device is externally receiving and collecting device.

[0005] Furthermore, the clamping device includes a first clamping assembly and a second clamping assembly, the first clamping assembly and the second clamping assembly are arranged in parallel and located on one side and the other side of the pipe valve, and the first clamping assembly and the second clamping assembly are connected by an adjusting assembly; The sewage diversion device includes a diversion component and a sealing component. The diversion component is installed in the middle of the first clamping component, and the sealing component is installed on the outside of the diversion component.

[0006] Furthermore, the flow guiding assembly includes a flow guiding tube, which is installed in the middle of the first clamping assembly. One end of the flow guiding tube is located inside the first clamping assembly and is perpendicular to the axis of the second clamping assembly.

[0007] Furthermore, the flow guiding assembly also includes a flow guiding hole, which is opened in the middle of the first clamping assembly, and the flow guiding tube is installed in the flow guiding hole.

[0008] Furthermore, the distance between the top of the end of the guide tube and the inner side of the first clamping assembly is 5mm to 7mm.

[0009] Furthermore, the sealing assembly includes a sealing gasket, and multiple sealing gaskets are provided, with the multiple sealing gaskets being arranged sequentially and at intervals on the outside of the flow guiding assembly.

[0010] Furthermore, the adjusting assembly includes a bolt, one end of which is connected to the first clamping assembly and the other end of which is connected to the second clamping assembly.

[0011] Furthermore, the liquid flow redirection device is a right-angle elbow or an irregularly shaped elbow.

[0012] Furthermore, the liquid drainage device has a tubular structure.

[0013] Secondly, a method for manufacturing a ball valve drain tool is provided, including: Two prefabricated clamping plates with identical structures are used, and a guide tube is welded onto one of the clamping plates. The distance between the end of the guide tube and the inner wall of the clamping plate is 5mm to 7mm. The inner and outer sides of the guide tube are ground and polished to make it fit with the drain hole of the valve. A liquid drainage device is installed on the guide tube away from the clamping plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The clamping device effectively fixes the tool to both sides of the stopcock, allowing the sewage discharge guide device to be smoothly inserted into the sewage discharge hole and seal it, thus solving the problem of sewage splashing and avoiding the risk of solid waste generation. Secondly, during the sewage discharge process, because the sewage discharge hole is effectively sealed, the staff can control the opening of the stopcock in real time, preventing fires and explosions caused by natural gas leaks.

[0015] 2. The first and second clamping components are arranged parallel to each other on both sides of the pipe stopcock, providing a stable clamping force to ensure that the draining tool can be firmly installed on the pipe stopcock and is not easy to fall off or loosen. Furthermore, by adjusting the connection between the first and second clamping components, the size and tightness of the clamping device can be easily adjusted to accommodate pipe stopcocks of different specifications and sizes, improving the versatility and adaptability of the draining tool.

[0016] 3. The guide tube is installed in the middle of the first clamping assembly, and one end of it is located inside the first clamping assembly and perpendicular to the axis of the second clamping assembly.

[0017] 4. The guide hole is located in the middle of the first clamping assembly, providing a precise installation position for the guide tube and ensuring that the guide tube can be accurately aligned with the drain hole of the pipe plug, thereby achieving precise guidance of the drain liquid.

[0018] 5. Maintaining an appropriate distance between the top of the guide tube and the inner side of the first clamping assembly can avoid excessive fluid resistance during the sewage discharge process.

[0019] 6. Multiple sealing gaskets are arranged sequentially and at intervals on the outside of the flow guiding component, forming multiple sealing barriers, which can greatly improve the sealing performance between the sewage discharge tool and the sewage discharge hole of the pipe plug, and effectively prevent liquid leakage during the sewage discharge process.

[0020] 7. Bolts, as connecting parts, can be flexibly adjusted in length and tightness. By rotating the bolts, the distance between the first clamping assembly and the second clamping assembly can be easily changed, thereby achieving precise control of the clamping force of the sewage discharge tool.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0028] During the use of natural gas gathering and transmission stations and long-distance natural gas pipelines, it is necessary to regularly inject cleaning fluid into the ball valves installed on them to drain and maintain the valves, ensuring they are in good working condition. However, in recent years, due to the increased demand for natural gas, the pressure to ensure supply in winter has risen. As a result, liquid accumulates in the valve chambers of natural gas pipeline ball valves, and the amount accumulates. The current method of handling this is manual drainage. During manual drainage, there is a problem of liquid splashing. This splashed liquid can contaminate nearby equipment, the ground, and personnel clothing, creating a risk of solid waste. In addition, if the valve opening is not properly controlled during manual drainage, it can cause a large amount of natural gas leakage, which can easily lead to personnel asphyxiation and cause fires and explosions.

[0029] To address the aforementioned technical deficiencies, the inventors have provided a ball valve sewage discharge tool and its manufacturing method.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings: like Figures 1-5 As shown, in a first aspect of the present invention, a ball valve draining tool is provided, including a clamping device 1. The clamping device 1 is mounted on a pipe stopcock and is used to position a draining guide device above the drain hole of the stopcock. The draining guide device mounted on the clamping device 1 is used to connect to the drain hole of the pipe stopcock to guide the sewage accumulated inside the ball valve cavity outward. A liquid flow diversion device 5 is installed at the end of the draining guide device, one end of which is connected to the draining guide device, and the other end is connected to a liquid guiding device 6. The end of the liquid guiding device 6 is externally receiving and collecting device. The liquid flow diversion device 5 is used to transport the sewage to the liquid diversion device 6, and the liquid diversion device 6 is used to finally divert the sewage into the collection device. During the sewage discharge process of the ball valve chamber, the sewage diversion device can be smoothly inserted into the sewage hole and block the sewage hole, which solves the problem of sewage splashing and avoids the risk of solid waste. Secondly, during the sewage discharge process, because the sewage hole is effectively blocked, the staff can control the opening of the valve in real time to avoid fire and explosion caused by natural gas leakage.

[0031] like Figure 1 and Figure 2 As shown, the clamping device 1 includes a first clamping assembly and a second clamping assembly. The first clamping assembly and the second clamping assembly have the same structure and are arranged in parallel. Furthermore, by positioning the first and second clamping components on one and the other sides of the pipe stopcock, and by arranging them in parallel, the first and second clamping components ensure that the sewage discharge tool is securely installed on the pipe stopcock when it is clamped, preventing it from easily falling off or loosening and thus ensuring proper sewage discharge operations. Secondly, an adjusting component is installed between the first and second clamping components, allowing for easy adjustment of the distance between them, which controls the clamping force on the pipe stopcock, further enhancing the stability of the sewage discharge tool's installation. Moreover, the installation of the adjusting component allows for adaptive adjustment of the distance between the first and second clamping components during clamping, based on different pipe sizes and stopcock dimensions, thus improving the overall versatility and adaptability of the sewage discharge tool.

[0032] Furthermore, the sewage diversion device includes a diversion component and a sealing component. The diversion component is installed in the middle of the first clamping component, while the sealing component is installed on the outside of the diversion component. The sealing component includes multiple sealing gaskets, which are spaced apart and arranged sequentially on the outside of the diversion component. When the diversion component is inserted into the drain hole of the stopcock, the sewage inside the ball valve cavity permeates outward through the diversion component. The multiple sealing gaskets block and intercept the sewage, preventing it from spraying outward and contaminating nearby equipment, the ground, and personnel clothing, thus avoiding the risk of solid waste. In specific applications, the diversion component preferably uses a diversion pipe 4 and a diversion hole, with the diversion hole located in the middle of the first clamping component. Figure 5 As shown, the guide hole is located in the middle of the first clamping assembly, providing a precise installation position for the guide tube 4. This ensures that the guide tube 4 can be accurately aligned with the drain hole of the pipe stopcock, achieving precise guidance of the drained liquid. The guide tube 4 can be made of steel pipe and is installed in the guide hole. The entire guide tube 4 is perpendicular to the axis of the second clamping assembly, allowing the drained liquid to be precisely guided out of the drain hole in a predetermined direction, perpendicular to the axis of the pipe stopcock. This reduces splashing and diffusion of the drained liquid, lowering environmental pollution and operational risks. The distance between the top of the guide tube 4 near the second clamping assembly and the inner side of the first clamping assembly is 5mm~7mm. This maintains an appropriate distance during the draining process, preventing excessive fluid resistance.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, the adjusting assembly includes bolt 3. To effectively adjust the distance between the first clamping assembly and the second clamping assembly, ensuring a more secure clamping of the valve during operation, adjusting holes are provided on both the first and second clamping assemblies. Figure 5As shown, adjustment holes are located at both ends of the first and second clamping components. Two bolts 3 are used to connect the first and second clamping components. Washers 2 and nuts are installed on the ends of the bolts 3 furthest from the first and second clamping components. The advantage of using bolts 3 as connectors is that the distance between the first and second clamping components can be flexibly adjusted. By rotating the bolts 3, the clamping force between the first and second clamping components can be easily changed, thereby achieving precise control of the clamping force of the sewage discharge tool.

[0034] like Figure 1 and Figure 3 As shown, in one embodiment, the liquid flow redirection device 5 is a right-angle elbow; in another embodiment, it is an irregularly shaped elbow. When a right-angle elbow is used, the liquid diversion device 6 is a tubular structure and a straight pipe with a length of 210 mm. In this case, the collection device is located near the stopcock, and the waste liquid can be directly transported to the collection device for recycling or treatment through the liquid diversion device 6. When an irregularly shaped elbow is used, the collection device is located further away from the stopcock and can be connected to an external bend or a longer pipeline.

[0035] Secondly, this embodiment provides a method for manufacturing a ball valve draining tool, such as... Figure 6 As shown, it includes: S101. Two prefabricated clamping plates with identical structures are used, and a guide pipe is welded onto one of the clamping plates. The distance between the end of the guide pipe and the inner wall of the clamping plate is 5mm to 7mm. For example, two steel plates of the same size are selected as clamping plates, and bolt holes are opened at the same position on the two steel plates. A guide hole is opened on one of the steel plates, and a steel guide pipe 4 is installed in the guide hole. The distance between the top of the end of the guide pipe 4 inserted into the drain hole and the inner wall of the clamping plate is adjusted to 5mm to 7mm.

[0036] S102. Grind and polish the inner and outer sides of the guide tube so that it can fit with the drain hole of the stopcock; use a grinder to grind the two clamping plates and the guide tube 4 so that their surfaces are smooth, so that when draining the inside of the ball valve cavity, the guide tube 4 can be smoothly inserted into the drain hole.

[0037] S103. Install a liquid diversion device on the guide pipe away from the clamping plate. For example, after the guide pipe 4 is installed, a straight elbow or a bend elbow is selected to connect the guide pipe 4 to the liquid diversion device 6 according to the arrangement position of the collection device. The liquid diversion device 6 can directly transport the sewage inside the ball valve cavity to the collection device for treatment.

[0038] The clamping device effectively secures the tool to both sides of the stopcock, allowing the sewage discharge guide device to be smoothly inserted into the sewage discharge hole and seal it, thus solving the problem of sewage splashing and avoiding the risk of solid waste generation. Secondly, during the sewage discharge process, because the sewage discharge hole is effectively sealed, the staff can control the opening of the stopcock in real time, preventing fires and explosions caused by natural gas leaks.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit its scope of protection. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading the present invention, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the invention, but these changes, modifications or equivalent substitutions are all within the scope of protection of the pending claims of the invention.
