Abstract
Description
Technical Field
[0001] This utility model relates to the field of ball valve technology, specifically to a ball-type quick-opening valve. Background Technology
[0002] A ball valve is a commonly used type of valve, mainly used to cut off or connect the medium in a pipeline. It can also be used for fluid regulation and control. It consists of a ball and two sealing surfaces, and the flow of the medium is controlled by rotating the ball.
[0003] Currently, the connection between the valve stem and the handle switch is usually exposed, making it susceptible to external environmental influences, resulting in corrosion and damage. This affects the aesthetics of the ball valve and makes subsequent disassembly and maintenance more troublesome. Furthermore, ball valves lack the constraint of the valve core, making it impossible to effectively determine the degree of valve core opening and closing. There is an urgent need to design a ball-type quick-opening valve to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a ball-type quick-opening valve to address the aforementioned shortcomings in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A ball-type quick-opening valve includes a valve body with connecting pipes on both opposite outer sides. A ball core is rotatably fitted inside the valve body, and a valve stem is inserted into the top of the ball core. A valve cover is installed on the top of the valve body, and the valve stem passes through the valve cover and rotatably engages with it. A rotary switch is installed at the top of the valve stem, and a mounting groove is formed on the top of the rotary switch. A cover plate is snapped into the mounting groove. Multiple grooves and multiple protrusions are provided on the periphery of the rotary switch. A limit mechanism is provided between the ball core and the valve body.
[0007] Furthermore, the valve cover is provided with external threads on its periphery, and the valve body is provided with internal threads on its top end, with the external threads engaging with the internal threads.
[0008] Furthermore, the bottom of the valve stem is provided with an insert block, the top of the ball core is provided with a slot, the insert block is inserted into the slot, the circumference of the valve stem is rotatably fitted with a rotating ring, and the bottom of the valve cover is provided with a fixing groove corresponding to the rotating ring.
[0009] Furthermore, the limiting mechanism includes a limiting block disposed at the bottom of the ball core, a slot formed at the bottom of the inner wall of the valve body, a limiting plate installed at the bottom of the slot, and two sector-shaped slots formed at the bottom of the limiting block. The two sector-shaped slots are symmetrically arranged and connected to each other. The limiting plate is rotatably fitted within the two sector-shaped slots.
[0010] Furthermore, each of the two connecting pipes is provided with a limit ring, and the valve body is provided with two rubber gaskets that abut against the two limit rings, and the two rubber gaskets abut against the two sides of the ball core respectively.
[0011] Furthermore, a connecting block is provided at the top of the valve stem, the connecting block passes through the bottom of the rotary switch and enters the mounting groove, a fixing bolt is provided at the top of the connecting block, multiple retaining plates are provided on the periphery of the cover plate, and multiple retaining slots are opened on the periphery of the mounting groove, the retaining plates engaging with the retaining slots.
[0012] In the above technical solution, the ball-type quick-opening valve provided by this utility model has the following advantages:
[0013] The cover plate shields the mounting groove and protects the connection between the rotary switch and the valve stem, reducing the impact of the external environment on this connection. This minimizes corrosion and damage, reducing difficulties in use and maintenance, and improves the aesthetics of the ball valve. The grooves and protrusions around the rotary switch facilitate gripping and rotation. The limiting mechanism restricts the ball core's rotation within a certain range, allowing for effective control of the valve's operation and facilitating its use. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0021] like Figure 1-4 As shown in the figure, this utility model provides a ball-type quick-opening valve.
[0022] The valve body includes a valve body 1, with connecting pipes 2 on both opposite outer sides. A ball core 3 is rotatably fitted inside the valve body 1, and a valve stem 4 is inserted into the top of the ball core 3. A valve cover 5 is installed on the top of the valve body 1, and the valve stem 4 passes through the valve cover 5 and rotatably fits with it. A rotary switch 6 is installed at the top of the valve stem 4, and an installation groove 7 is opened on the top of the rotary switch 6. A cover plate 8 is snapped into the installation groove 7. Multiple grooves and multiple protrusions are provided around the rotary switch 6. A limit mechanism 9 is provided between the ball core 3 and the valve body 1.
[0023] Reference Figure 2 In this embodiment, the valve cover 5 is provided with an external thread 10 on its periphery, and the valve body 1 is provided with an internal thread 11 at its top end. The external thread 10 and the internal thread 11 are threadedly engaged. Through the external thread 10 and the internal thread 11, the valve cover 5 can be rotated to form a threaded connection, so that the valve cover 5 is installed on the valve body 1.
[0024] Reference Figure 2 In this embodiment, the valve stem 4 has a plug 12 at its bottom and a slot 13 at its top. The plug 12 is inserted into the slot 13. A rotating ring 14 is rotatably fitted around the valve stem 4. The bottom of the valve cover 5 has a fixing groove 15 corresponding to the rotating ring 14. The plug 12 can be inserted into the slot 13 to connect the valve stem 4 and the ball core 3. Then, the valve cover 5 is installed to fix the valve stem 4 and the ball core 3. The rotating ring 14 enters the fixing groove 15, ensuring that the rotation of the valve cover 5 and the valve stem 4 does not affect each other.
[0025] Reference Figure 3The limiting mechanism 9 in this embodiment includes a limiting block 16 disposed at the bottom of the ball core 3, a slot 17 formed at the bottom of the inner wall of the valve body 1, a limiting plate 18 installed at the bottom of the slot 17, and two sector-shaped slots 19 formed at the bottom of the limiting block 16. The two sector-shaped slots 19 are symmetrically arranged and connected. The limiting plate 18 is rotatably engaged within the two sector-shaped slots 19. After the ball core 3 is placed into the valve body 1 through the limiting plate 18, the limiting block 16 enters the slot 17, and the limiting plate 18 enters the two sector-shaped slots 19. Rotating the ball core 3 will cause the sector-shaped slots 19 to move, and the limiting plate 18 will limit the ball core 3 through the sector-shaped slots 19.
[0026] Reference Figure 3 In this embodiment, each of the two connecting pipes 2 is provided with a limiting ring 20, and the valve body 1 is provided with two rubber gaskets 21 that abut against the two limiting rings 20. The two rubber gaskets 21 abut against both sides of the ball core 3 respectively. The rubber gaskets 21 can be fixed to both sides of the ball core 3, so that the rubber gaskets 21 seal between the ball core 3 and the valve body 1.
[0027] Reference Figure 4 In this embodiment, a connecting block 22 is provided at the top of the valve stem 4. The connecting block 22 passes through the bottom of the rotary switch 6 and enters the mounting groove 7. A fixing bolt 23 is provided at the top of the connecting block 22. Multiple retaining plates 24 are provided on the periphery of the cover plate 8. Multiple retaining slots 25 are opened on the periphery of the mounting groove 7. The retaining plates 24 and retaining slots 25 engage with each other. Through the connecting block 22, the connecting block 22 can pass through the bottom of the rotary switch 6 and enter the mounting groove 7, so that the fixing bolt 23 and the connecting block 22 are connected in the mounting groove 7. The fixing bolt 23 presses the rotary switch 6 to fix it. When the cover plate 8 is closed, the retaining plates 24 enter the corresponding retaining slots 25 to engage and fix the cover plate 8.
[0028] Working principle: In use, first connect the two connecting pipes 2 to the external pipeline. Use the ball core 3 in the valve body 1 to control the fluid in the pipeline. Hold the rotary switch 6 and rotate it, so that the rotary switch 6 drives the valve stem 4 to rotate. The valve stem 4 will drive the ball core 3 to rotate. Adjust the switch of the ball core 3. When the ball core 3 rotates, it will be limited by the limiting mechanism 9. When the ball core 3 is fully open, it will limit the rotation to prevent the ball core 3 from rotating excessively. When the ball core 3 is fully closed, it will also limit the rotation. Open the cover plate 8 on the top of the rotary switch 6 to expose the mounting groove 7, so that the connection between the rotary switch 6 and the valve stem 4 is exposed. Covering the connection with the cover plate 8 can protect the connection. After opening the cover plate 8, the rotary switch 6, valve cover 5, valve stem 4 and ball core 3 can be disassembled in sequence for maintenance.
[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
