Technical Field

[0001] This utility model relates to the field of pneumatic ball valve technology, and in particular to a double-seal pneumatic ball valve. Background Technology

[0002] Pneumatic ball valves can be classified as follows: stainless steel pneumatic ball valves, plastic pneumatic ball valves, sanitary pneumatic ball valves, carbon steel pneumatic ball valves, two-way pneumatic ball valves, three-way pneumatic ball valves, and four-way pneumatic ball valves. A pneumatic ball valve is a ball valve equipped with a pneumatic actuator. The pneumatic actuator has a relatively fast operating speed, with the fastest switching speed being 0.05 seconds per cycle. Therefore, it is also commonly referred to as a pneumatic quick-shut-off ball valve.

[0003] In existing technologies, pneumatic ball valves are prone to malfunctions and require maintenance due to material aging and wear of the pneumatic components over long-term use. Disassembling a pneumatic ball valve requires considerable patience and expertise, as accurate reassembly is essential; otherwise, the valve may malfunction or operate slowly. Furthermore, the disassembly and installation process can easily damage sealing elements, such as O-rings and other non-metallic parts. Damage to these components affects the valve's sealing performance. Therefore, a double-seal pneumatic ball valve is needed to meet these requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a double-seal pneumatic ball valve to solve the problem of inconvenient disassembly, assembly and maintenance of pneumatic ball valves mentioned in the background art.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A double-seal pneumatic ball valve includes a ball valve assembly 100, a drive assembly 101 disposed on the ball valve assembly 100, an arc-shaped mounting bracket 200 disposed on the ball valve assembly 100, a support bracket 300 fixedly mounted on the top side of the arc-shaped mounting bracket 200, a receiving bracket 301 fixedly mounted on the top side of the support bracket 300, the drive assembly 101 disposed on the receiving bracket 301, a base buckle 102 disposed on the ball valve assembly 100, and a connecting buckle 103 disposed on the bottom side of the drive assembly 101. The base buckle 102 and the connecting buckle 103 are compatible. The design of the base buckle 102 and the connecting buckle 103 separates the ball valve assembly 100 and the drive assembly 101. In actual maintenance operations, the drive assembly 101, which is prone to failure, can be removed and maintained separately, while the ball valve assembly 100, which is already connected to the pipeline, remains in its original position. This facilitates maintenance personnel in maintaining the device, and the disassembly and assembly are convenient and quick. It also avoids the problem of reduced sealing at the connection between the ball valve assembly 100 and the pipeline due to repeated disassembly and assembly.

[0022] In an optional embodiment: the base buckle 102 has a snap-fit ​​groove 400, and a sliding snap-fit ​​block 401 is slidably installed on the bottom side of the connecting buckle 103. The sliding snap-fit ​​block 401 is inserted into the snap-fit ​​groove 400. The base buckle 102 has an arc surface 406, which is adapted to the sliding snap-fit ​​block 401.

[0023] It should be noted that when the connecting buckle 103 is pressed down, the sliding latch block 401 comes into contact with the arc surface 406, and is naturally pushed open and expanded, so that the sliding latch block 401 enters the base buckle 102 and achieves connection with the base buckle 102.

[0024] In an optional embodiment: a sliding groove 402 is provided on the bottom side of the connecting buckle 103, and a sliding block 403 is slidably installed in the sliding groove 402. The sliding block 403 is fixedly installed on the top side of the sliding snap block 401.

[0025] It should be noted that the movable sliding block 401 drives the sliding block 403 to slide within the sliding groove 402. The sliding block 401 is restricted by the sliding groove 402 and the sliding block 403, and can only move within a fixed range.

[0026] In an optional embodiment: a slide rod 404 is slidably mounted on the slide block 403, the slide rod 404 is fixedly mounted on the inner wall of the slide groove 402, and a return spring 405 is movably sleeved on the slide rod 404, with the two ends of the return spring 405 respectively fixedly mounted on the inner walls of the slide block 403 and the slide groove 402.

[0027] It should be noted that after the position of the sliding latch block 401 changes, the sliding latch block 401 can be pushed outward to disengage it from the base buckle 102, thus separating the base buckle 102 from the connecting buckle 103. While the sliding block 403 is moving, it will also stretch the return spring 405. Therefore, after the sliding latch block 401 is released, the sliding latch block 401 can be reset by the pulling force of the return spring 405.

[0028] In an optional embodiment: a bottom arc-shaped mounting bracket 201 is arranged on the bottom side of the ball valve assembly 100, and a mounting bolt 202 is threaded between the bottom arc-shaped mounting bracket 201 and the arc-shaped mounting bracket 200.

[0029] It should be noted that when it is necessary to remove the drive assembly 101, the connection between the arc-shaped mounting bracket 200 and the bottom arc-shaped mounting bracket 201 should be released using the mounting bolt 202.

[0030] In an optional embodiment: a reinforcing bracket 302 is fixedly installed on the inner wall of the support frame 300, and the reinforcing bracket 302 has an X structure.

[0031] It should be noted that the reinforcing bracket 302 is used to enhance the support stability of the support frame 300.

[0032] In an optional embodiment: a hook 500 is fixedly installed on the support frame 300, a manual handle 501 is suspended on the hook 500, a connecting component 502 is arranged on the manual handle 501, the connecting component 502 and the base buckle 102 cooperate with each other, the connecting component 502 includes a number of buckles arranged in a ring, the buckles are snapped into the base buckle 102 to realize the cooperation between the connecting component 502 and the base buckle 102.

[0033] It should be noted that after the drive assembly 101 is completely removed, the manual handle 501 can be removed from the hook 500. The opening and closing of the ball valve assembly 100 can be controlled by the connecting assembly 502 on the manual handle 501 in conjunction with the base buckle 102, so that the normal use of the device can be maintained without affecting the device.

[0034] Working principle of this utility model:

[0035] The design using base clip 102 and connecting clip 103 separates the ball valve assembly 100 and drive assembly 101. In actual maintenance, the easily malfunctioning drive assembly 101 can be removed for separate maintenance, while the ball valve assembly 100, already connected to the pipeline, remains in its original position. This facilitates maintenance personnel in maintaining the device, making disassembly and assembly quick and easy. It also avoids the problem of decreased sealing at the connection between the ball valve assembly 100 and the pipeline due to repeated disassembly and assembly. When it is necessary to remove the drive assembly 101, use mounting bolt 202 to disconnect the arc-shaped mounting bracket 200 and the bottom arc-shaped mounting bracket 201. Then, push the sliding locking block 401 outward to release its fixation to the base clip 102. The movable sliding locking block 401 drives the sliding block 403 to slide within the sliding groove 402. The sliding locking block 401 is controlled by the sliding groove 402. Due to the limitation of the sliding block 403, it can only move within a fixed range. After the position of the sliding latch block 401 changes, the base buckle 102 and the connecting buckle 103 can be separated by lifting. While the sliding block 403 is moving, it will also stretch the return spring 405. Thus, after the sliding latch block 401 is released, the sliding latch block 401 can be reset by the pulling force of the return spring 405. The sliding latch block 401 can also be locked into the latching groove 400 of the base buckle 102 by pressing down. The sliding latch block 401 contacts the arc surface 406 and is naturally pushed open and expanded. After the drive assembly 101 is completely removed, the manual handle 501 can be removed from the hook 500. The opening and closing of the ball valve assembly 100 can be controlled by the connecting assembly 502 on the manual handle 501 in conjunction with the base buckle 102, so that the normal use of the device is not affected while maintaining the device.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
