Description

Technical Field

[0001] This application relates to the field of valve body technology, and in particular to a ball valve for modified vehicles with strong sealing performance. Background Technology

[0002] As a core component in the field of fluid control, ball valves are widely used in the fuel systems, lubrication circuits, coolant pipelines, and high-performance fluid delivery scenarios (such as nitrogen acceleration systems and water-methanol injection systems) of modified vehicles due to their simple structure and rapid opening and closing.

[0003] However, existing ball valves for modified vehicles have the following drawbacks: for example, the sealing at the ball valve connection cannot be guaranteed, and there is no residual repair design after a partial leak, making it impossible to quickly determine whether there is a leak after the vehicle is cleaned. Utility Model Content

[0004] The purpose of this application is to provide a robust sealing ball valve for modified vehicles with a residual maintenance design.

[0005] To achieve the above objectives, this application provides a modified vehicle ball valve with strong sealing performance, including a valve body, a sealing sleeve, a connecting pipe, an internally threaded connector, and a sealing ring. The valve body has an internally threaded connector on its side. One end of the sealing sleeve is ultrasonically welded to the outside of the internally threaded connector. The inside of the sealing sleeve and the end of the internally threaded connector form a step. The first end of the connecting pipe passes through the sealing sleeve and is threaded to the inside of the internally threaded connector. A sealing ring corresponding to the inside of the sealing sleeve is provided on the outside of the connecting pipe. The sealing sleeve is made of transparent material, and a second seal is formed between the sealing sleeve and the sealing ring. The transparent material of the sealing sleeve allows for observation of whether there is any leakage at the second seal, facilitating maintenance.

[0006] As a preferred embodiment, the second end of the connecting pipe is integrally connected to the pipe body, that is, the connecting pipe and the pipe body are designed as a single structure. Compared with the traditional pipe body and connecting pipe installation structure, the integrated structure design of the connecting pipe and the pipe body has a better sealing effect.

[0007] As another preferred option, the second end of the connecting pipe is configured as a connecting part, and a limiting part is provided on the outside of the connecting part. The connecting part uses a commonly used flexible hose / rigid pipe connector, which is more convenient to use.

[0008] In a further preferred embodiment, the first end of the connecting pipe is provided with a third sealing element, which is an annular rubber sealing gasket. The third sealing element corresponds to the step formed by the inner side of the sealing jacket and the end of the internal threaded connector, and is pressed together with the third sealing element to form a sealing structure.

[0009] In a further preferred embodiment, the inner side of the sealing jacket is provided with a two-section circular groove, the upper layer of the two-section circular groove is provided with a first sealing element, the inner side of the first sealing element is provided with a fine hole, and the lower layer of the two-section circular groove forms an annular space. When liquid leaks, liquid accumulates inside the annular space to facilitate user inspection, and external rainwater washing will not affect the annular space.

[0010] Further preferably, a second sealing element is provided on the inner side of the sealing jacket and on the side of the two-section circular groove away from the internal threaded connector. The second sealing element is used to further increase the sealing effect.

[0011] Further preferably, the first and second seals are made of anti-aging sealing rubber.

[0012] Further preferably, the outer side of the internal threaded connector is hexagonal, which facilitates the use of a wrench to stabilize the internal threaded connector.

[0013] Compared with the prior art, the beneficial effects of this application are as follows:

[0014] (1) By ultrasonically welding the sealing sleeve on the outside of the internal thread connector, a sealing ring corresponding to the inside of the sealing sleeve is provided on the outside of the connecting pipe. A second seal is formed between the sealing sleeve and the sealing ring. The sealing sleeve is made of transparent material so that it is easy to observe whether there is any leakage liquid at the second seal, which is convenient for maintenance.

[0015] (2) By providing a two-section circular groove on the inner side of the sealing jacket, a first sealing element is provided on the upper layer of the two-section circular groove, and a fine hole is opened on the inner side of the first sealing element. The lower layer of the two-section circular groove forms an annular space. When the liquid leaks, the liquid accumulates inside the annular space, which is convenient for users to inspect and repair. Moreover, external rainwater washing will not affect the annular space. Attached Figure Description

[0025] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0026] like Figure 1-5 The modified car ball valve shown is used for fluid control during car modification. It includes a valve body 1, a sealing sleeve 6, a connecting pipe 2, an internal threaded connector 3, and a sealing ring 7. The valve body 1 has an internal threaded connector 3 on its side. One end of the sealing sleeve 6 is ultrasonically welded to the outside of the internal threaded connector 3. The inside of the sealing sleeve 6 and the end of the internal threaded connector 3 form a step. The first end of the connecting pipe 2 passes through the sealing sleeve 6 and is threaded to the inside of the internal threaded connector 3. The outside of the connecting pipe 2 is provided with a sealing ring 7 corresponding to the inside of the sealing sleeve 6. The sealing sleeve 6 is made of transparent material.

[0027] A second seal is formed between the sealing jacket 6 and the sealing ring 7. The sealing jacket 6 is made of transparent material so that it is possible to observe whether there is any leakage liquid at the second seal. This is a residual inspection design that facilitates maintenance.

[0028] In one embodiment, the second end of the connecting pipe 2 is integrally connected to the pipe body, that is, the connecting pipe 2 and the pipe body are designed as an integral structure. Compared with the traditional pipe body and connecting pipe 2 installation structure, the integral structure design of the connecting pipe 2 and the pipe body has a better sealing effect.

[0029] In another embodiment, the second end of the connecting pipe 2 is configured as a connecting part 4, and a limiting part 5 is provided on the outside of the connecting part 4. The connecting part 4 uses a commonly used flexible hose / rigid pipe connector, which is more convenient to use.

[0030] In one embodiment, a third sealing element 11 is provided at the first end of the connecting pipe 2. The third sealing element 11 is an annular rubber sealing gasket. The third sealing element 11 corresponds to the step formed by the inner side of the sealing jacket 6 and the end of the internal threaded connector 3, and is squeezed to form a sealing structure.

[0031] In one embodiment, a two-section circular groove 8 is provided on the inner side of the sealing jacket 6, a first sealing element 9 is provided on the upper layer of the two-section circular groove 8, and a fine hole is opened on the inner side of the first sealing element 9. The lower layer of the two-section circular groove 8 forms an annular space. When liquid leaks, liquid accumulates inside the annular space to facilitate user maintenance, and external rainwater washing will not affect the annular space.

[0032] In one embodiment, a second seal 10 is provided on the inner side of the sealing jacket 6 and on the side of the two-section circular groove 8 away from the internal threaded connector 3. The second seal 10 is used to further increase the sealing effect.

[0033] In one embodiment, the first seal 9 and the second seal 10 are anti-aging sealing rubbers.

[0034] In one embodiment, the outer side of the internal thread connector 3 is hexagonal, which facilitates the use of a wrench to stabilize the internal thread connector 3.

[0035] Working principle: The sealing sleeve 6 and the internal threaded connector 3 are fixed by ultrasonic welding during manufacturing, and the sealing performance can be tested during production. During installation, the first end of the connecting pipe 2 is inserted into the inside of the sealing sleeve 6. At this time, multiple seals are formed between the sealing ring 7 and the sealing sleeve 6. For example, the first end of the connecting pipe 2 is provided with a third sealing element 11, which is an annular rubber sealing gasket. The third sealing element 11 and the inner side of the sealing sleeve 6 correspond to the step formed by the end of the internal threaded connector 3, and are squeezed to form a sealing structure. The first sealing element 9 and the outer side of the sealing ring 7 form a sealing structure. The second sealing element 10 and the outer side of the sealing ring 7 form a sealing structure. In this way, multiple strong sealing structures can be formed. When the seal at the threaded connection between the internal threaded connector 3 and the connecting pipe 2 fails, liquid leaks into the space between the sealing ring 7 and the sealing sleeve 6 to form multiple seals. The sealing sleeve 6 is made of transparent material, and the user can directly observe the slight leakage.

[0036] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
