Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a ball valve that prevents accidental activation. Background Technology

[0002] A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the valve axis. It can also be used for fluid regulation and control. Hard-seal V-type ball valves, with their V-shaped ball core and hard alloy-faced metal seat, possess strong shearing force, making them particularly suitable for media containing fibers or small solid particles. Multi-port ball valves not only flexibly control the merging, splitting, and switching of flow directions in pipelines, but also allow the closure of any channel while connecting the other two.

[0003] For example, a ball valve with anti-accidental activation disclosed in Chinese patent literature (publication number: CN219755515U) includes a ball valve body and a valve stem. A metal cover is installed at the top of the ball valve body, and the valve stem passes through the metal cover. A locking assembly is installed between the valve stem and the metal cover. The locking assembly includes a positioning post sleeved on the outside of the valve stem. A positioning arc plate is provided on one side of the positioning post, and the outer teeth of the outer wall of the positioning post engage with the inner teeth of the positioning arc plate. This invention, through the locking assembly, fixes the position of the valve stem by the interlocking teeth of the positioning post and the positioning arc plate, preventing the valve plate inside the ball valve body from rotating. This avoids accidental activation of the disc handle from affecting the operation of the ball valve. When the valve stem rotates, pulling the lever outward disengages the positioning post and the positioning arc plate. When rotating to the next position, releasing the lever and the strong spring retracting the positioning arc plate resets it and re-engages with the positioning post.

[0004] However, the above solution still has the following shortcomings when implemented:

[0005] When it is necessary to turn and open the valve, the lever must be pulled manually to release the limit before the valve can be opened. However, since there is no limit mechanism after the lever is pulled, and there is a spring, the operator needs to use a lot of force with one hand to pull the lever and turn the disc handle with the other hand, which is very strenuous and inconvenient to operate.

[0006] Therefore, we propose a ball valve to prevent accidental activation. Utility Model Content

[0007] The purpose of this utility model is to solve the shortcomings of the existing technology. When it is necessary to rotate and open the valve, the lever needs to be pulled open manually to release the limit before the valve can be opened. However, since there is no limit mechanism after the lever is pulled open, and there is a spring, the operator needs to use a lot of force with one hand to pull open the lever and turn the disc handle with the other hand, which is very strenuous and inconvenient to operate.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An anti-accidental-touch ball valve includes a main pipe, an installation pipe at the top of the main pipe, a first installation housing on the left side of the installation pipe, a fixing rod inside the first installation housing, a lower fixing component mounted on the fixing rod, a second housing on the top of the first installation housing, a plurality of first sliding grooves on the front and back sides of the first installation housing, a first slider installed inside each of the plurality of first sliding grooves, a plurality of second sliding grooves on the front and back sides of the second housing, a second slider installed inside each of the plurality of second sliding grooves, and a limiting component inside the second housing for engaging the lower fixing component.

[0010] As a preferred embodiment of this utility model, the lower fixing component includes a limiting block, and a plurality of limiting teeth are installed on the top of the limiting block, and the plurality of limiting teeth and the limiting block are integrated into one piece.

[0011] As a preferred embodiment of this utility model, the limiting block is fixedly connected to the fixing rod, and the limiting block is slidably connected to a plurality of first sliders and a plurality of first sliding grooves.

[0012] As a preferred embodiment of this utility model, the limiting component includes a snap-fit ​​block, a pull rod is installed on the top of the snap-fit ​​block, and a plurality of snap-fit ​​teeth are installed on the bottom of the limiting tooth, wherein the plurality of snap-fit ​​teeth and the snap-fit ​​block are integrated into one piece.

[0013] As a preferred embodiment of this utility model, a limiting strip is also fixedly connected to the outer side of the snap-fit ​​block, and a limiting plate is fixed on the four sides of the inner wall of the second housing, with the limiting strip and the limiting plate mutually limiting each other.

[0014] As a preferred embodiment of this utility model, the locking teeth of the locking block and the limiting teeth of the limiting block are locked together. When the fixing rod is pulled, it can drive the first slider to slide in the first sliding groove, thereby driving the limiting block to move.

[0015] As a preferred embodiment of this utility model, the first mounting housing is connected to the mounting pipe. The mounting pipe is provided with a rotating rod inside. A rotating disk is installed on the top of the rotating rod. A locking gear is installed on the rotating rod. A locking component is engaged at the connection of the locking gear. The locking component is fixed to the fixing rod. A compression spring is also installed on the fixing rod. A dividing plate is fixed to one end of the compression spring. The dividing plate is fixed to the first mounting housing.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this utility model, through the design of the limiting component and the lower fixing component, after the fixing rod is pulled, its locking part and locking gear release each other from the limiting position. At this time, it is only necessary to push the lower fixing component downward so that the lower fixing component and the moved limiting component can be engaged with each other to form a limiting position. Then the rotating disk can be rotated without continuously pulling the fixing rod for a long time, saving time and effort. Attached Figure Description

[0029] Example

[0030] like Figure 1-6 As shown, this utility model provides a technical solution: a ball valve to prevent accidental contact, including a main pipe 1, which is the main part of the entire ball valve and undertakes the basic function of fluid transmission. An installation pipe 2 is provided at the top of the main pipe 1, which is used to install and accommodate some components related to the operation and control of the ball valve.

[0031] The first mounting housing 6 is installed on the left side of the installation pipe 2. It is an important mounting base for the ball valve control mechanism. The first mounting housing 6 has a fixing rod 22 inside. The fixing rod 22 plays a key transmission role in the whole operation. A lower fixing component is installed on the fixing rod 22. The lower fixing component cooperates with the fixing rod 22 to participate in the locking and unlocking operation of the ball valve.

[0032] The first mounting housing 6 has several first grooves 10 inside and on both the front and back sides. Each of the first grooves 10 has a first slider 11 installed inside. The design of these grooves and sliders allows the relevant components to slide stably in a specific direction, ensuring the accuracy and stability of the movement. The principle is that the first slider 11 slides in the first groove 10, which restricts the movement trajectory of the component, reduces unnecessary shaking and offset, and thus provides precise displacement control for subsequent operations.

[0033] The top of the first mounting housing 6 is fitted with a second housing 14, which also plays an important role in the control structure of the ball valve. The second housing 14 has several second slide grooves 15 inside and on both the front and back sides. Each of the second slide grooves 15 has a second slider 16 installed inside. This design is similar to the slide groove and slider structure of the first mounting housing 6. Both are designed to ensure the stable sliding of internal components in a specific direction, thus ensuring the precise operation of the entire control mechanism.

[0034] The second housing 14 has a limiting component inside, which is used to engage with the lower fixing component. This is one of the core parts of the ball valve's anti-accidental contact function. The ball valve is locked in a specific state by engaging with the lower fixing component.

[0035] The lower fixing component includes a limiting block 12, which is the main part of the lower fixing component and undertakes the main connection and limiting functions. Several limiting teeth 13 are installed on the top of the limiting block 12. The limiting teeth 13 and the limiting block 12 are integrated into one piece. This integrated design ensures the strength and stability of the structure and can withstand the corresponding force during use without being easily damaged. The limiting block 12 is fixedly connected to the fixing rod 22, so that the movement of the fixing rod 22 can be transmitted to the limiting block 12. At the same time, the limiting block 12 is slidably connected to several first sliding blocks 11 and several first sliding grooves 10 through several first sliding blocks 11. This connection method ensures that the limiting block 12 can slide accurately along the first sliding grooves 10 under the drive of the fixing rod 22.

[0036] The limiting component includes a snap-fit ​​block 17, which is the key part for snapping with the limiting block 12 in the lower fixing component. A pull rod 21 is installed on the top of the snap-fit ​​block 17, which facilitates the operation of the snap-fit ​​block 17 by the operator. Several snap-fit ​​teeth 18 are installed at the bottom of the limiting teeth 13. The several snap-fit ​​teeth 18 and the snap-fit ​​block 17 are integrated into one piece. This integrated design also ensures the strength and stability of the structure. A limiting strip 19 is also fixedly connected to the outside of the snap-fit ​​block 17. A limiting plate 20 is fixed on the four walls inside the second housing 14. The limiting strip 19 and the limiting plate 20 limit each other. This design limits the range of motion of the snap-fit ​​block 17, ensuring that it accurately snaps with or disengages from the lower fixing component within the specified space.

[0037] The locking teeth 18 of the locking block 17 and the limiting teeth 13 of the limiting block 12 are locked together. This locking method forms a stable connection structure. When the fixed rod 22 is pulled, it can drive the first slider 11 to slide in the first slide groove 10, thereby driving the limiting block 12 to move. The principle is that when the fixed rod 22 moves, through the fixed connection with the limiting block 12 and the sliding cooperation of the slider in the slide groove, the limiting block 12 can accurately move to the position where it locks with the locking block 17, thereby realizing the locking function.

[0038] The first mounting housing 6 is connected to the mounting pipe 2. The mounting pipe 2 has a rotating rod 3 inside. The rotating rod 3 is the direct operating component for controlling the ball valve switch. A rotating disk 5 is installed on the top of the rotating rod 3. The operator opens and closes the ball valve by rotating the rotating disk 5. A locking gear 4 is installed on the rotating rod 3. The locking gear 4 is used to cooperate with other components to achieve the locking state of the ball valve. A locking element 8 is engaged at the connection of the locking gear 4. The locking element 8 is fixed to the fixed rod 22. This connection method allows the movement of the fixed rod 22 to affect the engagement state between the locking gear 4 and the locking element 8. A compression spring 9 is also installed on the fixed rod 22. A dividing plate 7 is fixed to one end of the compression spring 9. The dividing plate 7 is fixed to the first mounting housing 6. The compression spring 9 plays the role of reset and auxiliary force during the entire operation.

[0039] In summary, in the initial state, the ball valve is in a locked state, the locking component 8 and the locking gear 4 are engaged with each other, restricting the rotation of the rotating rod 3, and the lower fixed component is in a limit component engaged state.

[0040] When the ball valve needs to be operated, the operator first needs to pull the pull rod 21 to disengage the locking block 17 from the limiting block 12 and release the limit. Then, pull the fixing rod 22. The fixing rod 22 drives the locking piece 8 and the locking gear 4 to release the limit. At the same time, the fixing rod 22 moves the fixing component through the sliding of the slider in the slide groove.

[0041] Next, push the lower fixing component downward. Under the action of the fixing rod 22 and the sliding block, the lower fixing component engages with the moved limiting component to form a limit. At this time, the fixing rod 22 no longer needs to be pulled continuously.

[0042] The operator can rotate the rotating disc 5 and control the opening or closing of the ball valve by rotating the lever 3. After the operation is completed, the above steps are reversed. Under the action of the compression spring 9, all components are reset and the ball valve returns to the locked state.

[0043] 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.
