Description

Technical Field

[0001] This invention relates to the field of dual-chamber self-regulating valve technology, specifically to dual-chamber self-regulating valves. Background Technology

[0002] Dual-chamber self-regulating valves are automated fluid control devices with a dual-chamber structure. Their core function is to precisely control fluid flow, shut-off, and flow regulation through internal pressure regulation and valve core linkage mechanisms. Simultaneously, the dual-chamber isolation design effectively separates the internal fluid channels from the external environment, reducing the risk of fluid leakage and thus improving the safety and reliability of valve operation. Due to the stability and safety advantages brought by the dual-chamber structure, these valves are widely used in petrochemical, water supply and drainage, power generation, and biopharmaceutical industries. In these production processes, dual-chamber self-regulating valves undertake critical control tasks in fluid transportation, and are particularly suitable for transporting corrosive media, high-pressure fluids, or conditions with stringent sealing requirements. In such conditions, traditional single-chamber valves are prone to leakage and insufficient control precision, while dual-chamber self-regulating valves can overcome these issues through their structural features. Avoiding such problems is crucial for ensuring stable industrial production processes and safe fluid transport, significantly improving overall production efficiency and reducing safety hazards. However, in actual operation of dual-chamber self-controlled valves, traditional devices have gradually revealed problems: On the one hand, traditional dual-chamber self-controlled valves are susceptible to fluid impact and equipment vibration during operation, leading to loosening between the valve and the mounting surface. This not only affects the valve's positioning accuracy but may also exacerbate wear on internal precision components, shorten the valve's service life, and even cause safety hazards such as fluid leakage. On the other hand, the protective structure of traditional valves is difficult to assemble conveniently, and operators cannot directly observe the internal operating status of the valve, making it difficult to promptly detect and handle abnormalities such as valve jamming and leakage, further reducing the safety and ease of maintenance of valve operation. Therefore, those skilled in the art have provided dual-chamber self-controlled valves to solve the problems mentioned in the background art. Summary of the Invention

[0003] The purpose of this invention is to provide a dual-chamber self-regulating valve to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A dual-cavity self-regulating valve includes a dual-cavity self-regulating valve and a positioning structure. A connecting frame is fixedly connected to the upper part of one side of the dual-cavity self-regulating valve, and a positioning structure is fixedly connected to the bottom of the dual-cavity self-regulating valve.

[0006] As a further embodiment of the present invention: the positioning structure includes a fixing rod, a fixing block, a damping spring, a connecting slider, a connecting groove, and a positioning plate. The top of the positioning plate is provided with a connecting groove, and a connecting slider is slidably connected in the connecting groove.

[0007] As a further embodiment of the present invention: a fixing block is fixedly connected to the top of the connecting slider, and a fixing rod is fixedly connected to the top center of the fixing block; a fixing block is fixedly connected to the top of the connecting slider, and a fixing rod is fixedly connected to the top center of the fixing block.

[0008] As a further embodiment of the present invention: damping springs are fixedly connected to the four corners at the bottom of the fixing block, and the side of the damping springs away from the fixing block is fixedly connected to the positioning plate, and screws are threadedly connected to the four corners at the top of the positioning plate.

[0009] As a further embodiment of the present invention: a protective frame is connected to one side of the connecting frame, a groove is provided on one side of the protective frame, and an insert block corresponding to the groove is fixedly connected to the upper part of one side of the connecting frame, and the insert block is embedded in the groove.

[0010] As a further embodiment of the present invention: mounting plates are fixedly connected to the upper parts of both sides of the connecting frame, and each mounting plate is threadedly connected to the protective frame by two screws.

[0011] As a further embodiment of the present invention: a protective plate is fixedly connected to the top of the protective frame.

[0012] As a further improvement of the present invention, observation ports are provided on both sides of the protective frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In use, the device is first stabilized by the positioning structure at the bottom of the dual-chamber self-regulating valve. The positioning plate of the positioning structure has threaded screws at its four corners, allowing operators to securely fasten the positioning plate to the preset installation position, thus achieving initial positioning of the valve. Simultaneously, a connecting groove is provided at the top of the positioning plate. A sliding block within the groove is fixedly connected to the top fixing block, and the fixing rod at the center of the top of the fixing block is fixedly connected to the bottom of the dual-chamber self-regulating valve. Combined with the damping springs at the four corners of the fixing block that are fixedly connected to the positioning plate, the connecting block can slightly slide within the connecting groove during valve operation. This, along with the elastic buffering effect of the damping springs, effectively absorbs vibrations generated during valve operation, preventing the valve from loosening from the mounting surface and reducing damage to the valve's internal precision structure, thus ensuring valve operational stability.

[0015] 2. After the valve body is installed and fixed, the protective frame is assembled using the connecting bracket fixedly connected to the upper part of one side. During assembly, the insert on the upper part of one side of the connecting bracket is precisely aligned with the groove on the side of the protective frame and embedded connection is completed to achieve rapid pre-positioning of the protective frame. Then, using the mounting plates fixedly connected to the upper parts of both sides of the connecting bracket, the protective frame is firmly threaded to the connecting bracket using two screws on each mounting plate to ensure the stability of the protective frame after assembly. The protective plate fixedly connected to the top of the protective frame can effectively protect the upper structure of the valve, preventing external debris and dust from falling into the valve and affecting its normal operation. At the same time, the observation ports on both sides of the protective frame allow operators to observe the operating status inside the valve in real time, promptly detect and handle abnormalities such as valve jamming and leakage, and ensure the safe and stable operation of the valve under various working conditions.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides a dual-cavity self-regulating valve, including a dual-cavity self-regulating valve 1 and a positioning structure 5. A connecting frame 6 is fixedly connected to the upper part of one side of the dual-cavity self-regulating valve 1, and a positioning structure 5 is fixedly connected to the bottom of the dual-cavity self-regulating valve 1. A protective frame 2 is connected to one side of the connecting frame 6, and a groove 9 is opened on one side of the protective frame 2. A corresponding insert 8 is fixedly connected to the upper part of one side of the connecting frame 6, and the insert 8 is embedded in the groove 9. After the valve body is installed and fixed, the protective frame 2 is assembled through the connecting frame 6 fixedly connected to the upper part of one side. During assembly, the insert 8 on the upper part of one side of the connecting frame 6 is precisely aligned with the groove 9 on the side of the protective frame 2 and embedded in the groove to achieve rapid pre-positioning of the protective frame 2. The connecting frame 6 has two sides. Mounting plates 7 are fixedly connected to the upper part of the protective frame 2. Each mounting plate 7 is threadedly connected to the protective frame 2 by two screws. The protective frame 2 and the connecting frame 6 are firmly threadedly connected by the mounting plates 7 fixedly connected to the upper part of the connecting frame 6 by the two screws on each mounting plate 7, ensuring the stability of the protective frame 2 after assembly. A protective plate 3 is fixedly connected to the top of the protective frame 2. The protective plate 3 can effectively protect the upper structure of the valve and prevent external debris and dust from falling into the valve and affecting its normal operation. Observation ports 4 are opened on both sides of the protective frame 2. The observation ports 4 on both sides of the protective frame 2 can facilitate the operator to observe the internal operating status of the valve in real time, and promptly detect and deal with abnormalities such as valve jamming and leakage, so as to ensure the safe and stable operation of the valve under various working conditions.

[0025] Example 2

[0026] Reference Figure 1-5This embodiment is based on the previous embodiment, but differs in that the positioning structure 5 includes a fixing rod 51, a fixing block 52, a damping spring 53, a connecting slider 54, a connecting groove 55, and a positioning plate 56. The top of the positioning plate 56 has a connecting groove 55, within which the connecting slider 54 is slidably connected. The top of the connecting slider 54 is fixedly connected to the fixing block 52, and the top center of the fixing block 52 is fixedly connected to the fixing rod 51. Damping springs 53 are fixedly connected to the four corners of the bottom of the fixing block 52, with the side of the damping springs 53 furthest from the fixing block 52 fixedly connected to the positioning plate 56. Screws are threaded to the four corners of the top of the positioning plate 56. The positioning structure 5 at the bottom of the dual-cavity self-regulating valve 1 ensures stable fixation of the device. The positioning plate 56 of the positioning structure 5 is equipped with threaded screws at the four corners of its top. Operators can use these screws to firmly lock the positioning plate 56 to the preset installation position to achieve the initial positioning of the valve as a whole. At the same time, the top of the positioning plate 56 is provided with a connecting groove 55. The connecting slider 54, which is slidably connected in the connecting groove 55, is fixedly connected to the top fixing block 52. The fixing rod 51 in the middle of the top of the fixing block 52 is fixedly connected to the bottom of the double-cavity self-control valve 1. With the damping springs 53 at the four corners of the bottom of the fixing block 52 and fixedly connected to the positioning plate 56, the connecting slider 54 can slide slightly in the connecting groove 55 during valve operation. Combined with the elastic buffering effect of the damping springs 53, the vibration generated during valve operation is effectively absorbed, preventing the valve from loosening from the installation surface due to vibration. At the same time, it reduces the damage of vibration to the precision structure inside the valve and ensures the stability of valve operation.
