Description

Technical Field

[0001] This utility model relates to the field of high-pressure ball valve technology, specifically a leak-proof high-pressure ball valve structure. Background Technology

[0002] High-pressure ball valves are control valves used in high-pressure fluid systems. Their core structure includes a valve body, a ball with a through hole, and a sealing assembly. The flow is turned on and off by rotating the ball 90°. When the ball's through hole is aligned with the pipeline, the fluid is allowed to flow; when it is perpendicular, the flow is cut off. They are characterized by their compact structure and convenient operation. Therefore, they are widely used in industrial scenarios that require high-pressure sealing control, such as oil extraction, chemical pipelines, and hydraulic machinery.

[0003] According to the search results, Chinese patent document, publication number CN216895867U, discloses a sealing and leak-proof ball valve structure, including a ball valve body. A valve stem for rotating a ball inside the ball valve body is rotatably connected to the top of the ball valve body. The ball valve body has an inlet end on its left side and an outlet end on its right side. It also includes a first sealing component and a second sealing component. The first sealing component is used to seal the valve stem and is located outside the valve stem. The second sealing component is used to seal the inlet end and the outlet end. This invention, by providing the first sealing component, ensures that the first sealing ring is always in contact with the ball valve body.

[0004] During the connection process between the above-mentioned device and the pipeline, before the bolts are used for fixing, the connection end faces of the pipeline and the valve are prone to relative sliding due to the lack of a sliding constraint structure. At this time, the self-weight of the pipeline, slight collisions during installation, or external disturbances may cause the central axis of the two to shift, requiring repeated adjustment of the position of the pipeline or valve. If the bolts are tightened before they are fully aligned, some bolts will bear additional shear force, while others will be in a loose state. This will cause slight misalignment of the connection surface under uneven bolt load. The misaligned connection surface will repeatedly squeeze and rub the sealing material, causing it to age faster or even break, eventually leading to leakage. In view of this, we provide a leak-proof high-pressure ball valve structure. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a leak-proof high-pressure ball valve structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof high-pressure ball valve structure, including a valve body and pipelines, wherein multiple pipelines are provided, and the multiple pipelines are respectively located at both ends of the valve body. Multiple sealing rings are provided at both ends of the outer wall of the valve body. Multiple slide rails are fixedly connected to both ends of the outer wall of the valve body, and multiple limiting members are fixedly connected to both sides of the inner wall of the slide rails. A snap-fit ​​member is slidably connected to one end of the slide rail, and a compression spring is provided on the outer wall of the bottom end of the snap-fit ​​member.

[0007] The top of the outer wall of the limiting member passes through one side of the inner side of the snap-fit ​​member, and the top of the outer wall of the limiting member is slidably connected to one side of the inner side of the snap-fit ​​member.

[0008] As described above, the sealing ring has a symmetrical structure, and multiple waterproof plates are added to both sides of the outer wall of the sealing ring. The two sides of the outer wall of the sealing ring are tightly fitted to the outer wall of one end of the valve body and the inner wall of one end of the pipe, respectively, and the multiple waterproof plates added to both sides of the outer wall of the sealing ring extend into the interior of the valve body and the pipe.

[0009] As mentioned above, one end of the outer wall of the slide rail passes through the inner wall of the pipe and is slidably connected to it.

[0010] As described above, the top of the outer wall of the snap-fit ​​component penetrates the interior of the slide rail, and the top of the outer wall of the snap-fit ​​component extends into the interior of the pipe. One side of the top of the snap-fit ​​component is provided with an inclined surface, and one side of the top plane of the snap-fit ​​component is engaged and connected with the inner wall of the pipe.

[0011] As mentioned above, a pressure plate is added to one side of the outer wall of the snap-fit ​​component, and the pressure plate extends to one end of the slide rail.

[0012] As described above, the outer walls of the top ends of the multiple compression springs abut against both sides of the bottom surface of the snap-fit ​​component, and the outer walls of the bottom ends of the compression springs abut against the bottom ends of the inner walls of the slide rail.

[0013] Compared with existing technologies, this leak-proof high-pressure ball valve structure has the following advantages:

[0014] I. This utility model effectively constrains the sliding of the pipeline by setting multiple slide rails at both ends of the valve body outer wall and cooperating with the snap-fit ​​component. The slide rails can constrain the movement trajectory of the pipeline and prevent the end face of the pipeline and valve body from sliding in any direction. At the same time, when the pipeline approaches the valve body along the slide rail, the inclined surface at the top of the snap-fit ​​component will be squeezed by the inner wall of the pipeline. After the pipeline is fully in place, the compression spring rebounds and pushes the snap-fit ​​component upward, so that its top plane engages with the inner wall of the pipeline. After the relative position of the pipeline and the valve body is initially fixed, the pipeline's own weight or external force disturbance can no longer cause its axis to shift. The bolt holes can be accurately aligned without repeated adjustments, ensuring that there is no risk of misalignment of the connection surface.

[0015] Second, this utility model, through its symmetrical sealing ring structure and multiple waterproof plates added on both sides, enables technicians to tightly fit the connection surface between the valve body and the pipeline during installation, achieving a double sealing effect, further preventing high-pressure fluid from seeping through the connection gaps, and reducing the risk of leakage.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] 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.

[0025] like Figure 1-6As shown, this utility model provides a technical solution: a leak-proof high-pressure ball valve structure, including a valve body 1 and a pipeline 2. Multiple pipelines 2 are provided, and the multiple pipelines 2 are respectively located at both ends of the valve body 1. Multiple sealing rings 201 are provided at both ends of the outer wall of the valve body 1. Multiple slide rails 101 are fixedly connected to both ends of the outer wall of the valve body 1, and multiple limiting members 102 are fixedly connected to both sides of the inner wall of the slide rails 101. A snap-fit ​​member 103 is slidably connected to one end of the slide rail 101, and a compression spring 104 is provided on the outer wall of the bottom end of the snap-fit ​​member 103.

[0026] The top of the outer wall of the limiting member 102 passes through one side of the inner side of the snap-fit ​​member 103, and the top of the outer wall of the limiting member 102 is slidably connected to one side of the inner side of the snap-fit ​​member 103.

[0027] The slide rail 101 can constrain the movement trajectory of the pipe 2 on the end face of the valve body 1, preventing the end face of the pipe 2 from sliding in any direction between the connection surface of the pipe 2 and the valve body 1. At the same time, when the pipe 2 approaches the valve body 1 along the slide rail 101, the inclined surface at the top of the locking member 103 will be squeezed by the inner wall of the pipe 2. After the pipe 2 is fully in place, the compression spring 104 rebounds and pushes the locking member 103 upward, so that its top plane engages with the inner wall of the pipe 2. After the relative position of the pipe 2 and the valve body 1 is initially fixed, the self-weight of the pipe 2 or external force disturbance can no longer cause it to deviate from its axis.

[0028] like Figure 4 As shown, the sealing ring 201 has a symmetrical structure, and multiple waterproof plates 202 are added to both sides of the outer wall of the sealing ring 201. The two sides of the outer wall of the sealing ring 201 are tightly fitted to the outer wall of one end of the valve body 1 and the inner wall of one end of the pipe 2, respectively. The multiple waterproof plates 202 added to both sides of the outer wall of the sealing ring 201 extend into the interior of one end of the valve body 1 and the pipe 2, respectively.

[0029] The symmetrical structure of the sealing ring 201 allows for a tighter fit between the valve body 1 and the pipe 2. Meanwhile, the waterproof plate 202 is further embedded inside the valve body 1 and the pipe 2, forming a double sealing structure that prevents high-pressure fluid from seeping through the connection gap, significantly improving sealing reliability and reducing the risk of high-pressure fluid leakage.

[0030] like Figure 2 As shown, one end of the outer wall of the slide rail 101 passes through the inner wall of the pipe 2 and is slidably connected to its inner wall.

[0031] One end of the slide rail 101 passes through the inner wall of the pipe 2 and is slidably connected, providing a limiting track for the docking of the pipe 2 and the valve body 1. During installation, the pipe 2 can slide along the outer wall of the slide rail 101 and automatically align the valve body 1 and the central axis of the pipe 2.

[0032] like Figure 3As shown, the top of the outer wall of the snap-fit ​​member 103 penetrates the interior of the slide rail 101, and the top of the outer wall of the snap-fit ​​member 103 extends into the interior of the pipe 2. One side of the top of the snap-fit ​​member 103 is provided with an inclined surface, and one side of the top plane of the snap-fit ​​member 103 is snapped into connection with the inner wall of the pipe 2.

[0033] The inclined surface at the top of the snap-fit ​​component 103 will be pressed down by the inner wall of the pipe 2 when the pipe 2 slides along the slide rail 101. After the pipe 2 is fully in place, the compression spring 104 will rebound and push the snap-fit ​​component 103 to move upward, and its top plane will engage with the inner wall of the pipe 2 to fix the position of the pipe 2.

[0034] like Figure 5 As shown, a pressure plate 105 is added to one side of the outer wall of the snap-fit ​​member 103, and the pressure plate 105 extends to one end of the slide rail 101.

[0035] The pressure plate 105 added to one side of the snap-fit ​​component 103 extends to the outside of the slide rail 101. When it is necessary to disassemble the pipe 2, pressing the pressure plate 105 will press down the snap-fit ​​component 103, release its snap-fit ​​state with the inner wall of the pipe 2, and allow the pipe 2 to be smoothly disassembled along the slide rail 101.

[0036] like Figure 5 As shown, the outer walls of the top ends of multiple compression springs 104 abut against both sides of the bottom surface of the snap-fit ​​member 103, and the outer walls of the bottom ends of the compression springs 104 abut against the bottom ends of the inner walls of the slide rail 101.

[0037] The compression spring 104 abuts against the bottom of the snap-fit ​​member 103 and the inner wall of the slide rail 101, continuously providing an upward elastic force to ensure that the snap-fit ​​member 103 is always tightly engaged with the inner wall of the pipe 2.

[0038] Working principle: The symmetrical structure of the sealing ring 201 allows for a tighter fit between the valve body 1 and the pipe 2 connection surface. Simultaneously, the waterproof plate 202 is further embedded inside the valve body 1 and pipe 2, forming a double-sealing structure that prevents high-pressure fluid from seeping through the connection gap, significantly improving sealing reliability and reducing the risk of high-pressure fluid leakage. One end of the slide rail 101 passes through the inner wall of the pipe 2 and slides, providing a limiting track for the docking of the pipe 2 and valve body 1. During installation, the pipe 2 can slide along the outer wall of the slide rail 101, automatically aligning with the central axis of the valve body 1 and pipe 2. The inclined surface at the top of the locking component 103 is engaged. When the pipe 2 slides along the slide rail 101, it is held in place by the pipe 2... The inner wall is pressed down, and after the pipe 2 is fully in place, the compression spring 104 rebounds and pushes the snap-fit ​​component 103 upward. Its top plane engages with the inner wall of the pipe 2, fixing the position of the pipe 2. The pressure plate 105 added to one side of the snap-fit ​​component 103 extends to the outside of the slide rail 101. When it is necessary to disassemble the pipe 2, pressing the pressure plate 105 will press down the snap-fit ​​component 103, releasing its engagement with the inner wall of the pipe 2, so that the pipe 2 can be smoothly disassembled along the slide rail 101. The compression spring 104 abuts against the bottom of the snap-fit ​​component 103 and the inner wall of the slide rail 101, continuously providing upward elastic force to ensure that the snap-fit ​​component 103 is always tightly engaged with the inner wall of the pipe 2.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
