[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0025] Please see Figure 1-7 This utility model discloses a flexible connection pipeline pressure regulator, including a regulator body 1, and also including a moving component 2, a protective component 3, a housing component 4, a pressure regulating component 5, an input component 6, and an output component 7, wherein:
[0026] The movable component 2 includes a threaded seat 201, on the outer surface of which a threaded cylinder 202 is threadedly connected. Rotating the threaded cylinder 202 allows it to rise and fall, thereby driving the connecting rod 206 to rise and fall. A rotary groove 203 is formed on the outer surface of the threaded cylinder 202. The rotary groove 203 prevents the limiting block 204 from rotating during the rotation and rise of the threaded cylinder 202, instead causing the limiting block 204 to move up and down. The limiting block 204 is movably connected inside the rotary groove 203. 204 can connect the threaded cylinder 202 and the connecting block 205. When the threaded cylinder 202 rises and falls, it can drive the connecting block 205 to rise and fall. The side surface of the limiting block 204 is fixedly connected to the connecting block 205, and the upper end of the connecting block 205 is movably connected to the connecting rod 206. There are two limiting blocks 204, connecting blocks 205 and connecting rods 206, and they are mirror symmetrical along the central axis of the regulator body 1. When the threaded cylinder 202 rotates and rises and falls, it can drive the connecting rod 206 to move up and down.
[0027] The protective component 3 includes a mounting base 301. There are two protective components 3. A rotating base 302 is movably connected inside the mounting base 301. The rotating base 302 can rotate around the mounting base 301 as a fulcrum. A protective cover 303 is fixedly connected to the upper surface of the rotating base 302. When the two protective covers 303 are together, they form a tight protective barrier, preventing impact from external objects and preventing dust from entering. A pressure rod 304 is fixedly connected to the outer surface of the protective cover 303. One end of the pressure rod 304 is connected to the connecting rod 206. The upper end is movable. When the connecting rod 206 descends, it pulls the connecting position of the pressure rod 304 down, that is, the pressure rod 304 and the protective cover 303 rotate around the connection point of the mounting base 301 and the rotating base 302 as the fulcrum. The two protective covers 303 separate from each other, at which time the internally protected bolt knob 501 is exposed, and the spring preload can be adjusted. Conversely, when the connecting rod 206 rises, it pushes the connecting position of the pressure rod 304 up, which can push the two protective covers 303 together to form a tight protection.
[0028] The outer casing assembly 4 includes a lower outer casing 401, the lower end of which is fixedly connected to the upper surface of the regulator body 1. An upper outer casing 402 is fixedly connected to the upper surface of the lower outer casing 401. The outer surface of the upper outer casing 402 is fixedly connected to the inner surface of the threaded seat 201. A flow pipe 403 is fixedly connected inside the lower outer casing 401. Fluid from the output end can be transported into the lower outer casing 401 through the flow pipe 403 and blocked by the rubber diaphragm 504, thus applying upward pressure to the rubber diaphragm 504, which opposes the downward pressure of the pressure spring 503, thereby detecting and adjusting the pressure. Example 2
[0029] Based on the above embodiment one, please refer to the appendix. Figure 1-7The pressure regulating component 5 includes a bolt knob 501. By turning the bolt knob 501, it can be raised or lowered, which can push the pressure plate 502. The outer surface of the bolt knob 501 is threadedly connected to the top of the upper housing 402. The lower end of the bolt knob 501 is movably connected to the pressure plate 502. A pressure spring 503 is installed on the lower surface of the pressure plate 502. The pressure spring 503 is compressed by the pressure plate 502, and the reaction force generated by the compression can apply downward pressure to the rubber diaphragm 504.
[0030] A rubber diaphragm 504 is fixedly connected to the lower end of the pressure spring 503. The rubber diaphragm 504 is located between the lower housing 401 and the upper housing 402. The rubber diaphragm 504 bears the downward pressure of the pressure spring 503 and the upward pressure applied by the fluid. By comparing the downward pressure and the upward pressure, the magnitude of the output pressure and the downward pressure can be detected. A valve stem 505 is fixedly connected inside the rubber diaphragm 504.
[0031] The regulator body 1 has a through hole 101 inside, which serves as a channel for liquid and gas to pass through the regulator body 1, allowing liquid and gas to flow from one end of the regulator body 1 to the other. The lower end of the valve stem 505 extends through the interior of the regulator body 1 into the interior of the through hole 101. The lower end of the valve stem 505 is fixedly connected to the valve core 506. During the detection process, when the output pressure is greater than the downward pressure of the pressure spring 503, the pressure on the rubber diaphragm 504 increases, overcoming the downward pressure of the pressure spring 503 and moving upward. This causes the valve stem 505 to drive the valve core 506 upward, bringing the valve core 506 closer to the through hole 101, reducing the fluid flow rate, and thus lowering the output pressure until it is rebalanced with the downward pressure of the spring. Conversely, when the output pressure is less than the downward pressure, the downward pressure pushes the rubber diaphragm 504 downward, and the valve core 506 moves away from the through hole 101, increasing the fluid flow rate, and thus raising the output pressure until it is rebalanced with the downward pressure of the spring.
[0032] The input component 6 includes an input pipe 601. One end of the input pipe 601 is fixedly connected to the left side of the regulator body 1, and the other end of the input pipe 601 is fixedly connected to an input flange 602. A flexible connecting pipe 8 is fixedly connected to the side surface of the input flange 602. There are two flexible connecting pipes 8. The flexible connecting pipe 8 consists of a rubber pipe and a connecting flange on each side. One of the connecting flanges is fixed to the input flange 602 by a fixing bolt. The rubber pipe has good flexibility and can bend and expand freely within a certain range. It can compensate for the displacement caused by temperature changes, vibration, settlement and other factors during the installation and operation of the pipeline system, and at the same time play a role in vibration reduction and noise reduction.
[0033] The output assembly 7 includes an output pipe 701. One end of the output pipe 701 is fixedly connected to the right end of the regulator body 1. The outer surface of the output pipe 701 is fixedly connected to the lower end of the flow pipe 403. When the fluid passes through the output pipe 701, part of the fluid enters the lower housing 401 through the flow pipe 403, thereby applying pressure to the rubber diaphragm 504. The other end of the output pipe 701 is fixedly connected to an output flange 702. The side surface of the output flange 702 is fixedly connected to the side surface of another flexible connecting pipe 8. One of the connecting flanges is fixedly connected to the output flange 702 by fixing bolts.
[0034] The working principle and usage process of this utility model are as follows: First, the left and right ends of the two flexible connecting pipes 8 are connected to the flanges on both sides of the pipes by fixing bolts to complete the overall installation of the pressure regulator.
[0035] Then, rotate the threaded cylinder 202 to lower it. The connecting rod 206 pulls the pressure rod 304 to open the two protective covers 303. At this time, the bolt knob 501 can be turned to adjust the position of the pressure plate 502, thereby adjusting the preload of the pressure spring 503. After the adjustment is completed, rotate the threaded cylinder 202 in the opposite direction to raise it. The connecting rod 206 pushes the pressure rod 304 to make the two protective covers 303 close together to protect the bolt knob 501.
[0036] When the fluid flows through the pressure regulator body 1, the fluid passes through the left flexible connecting pipe 8, the input pipe 601, the through hole 101, the output pipe 701 and the right flexible connecting pipe 8 in sequence. At the same time, when the fluid passes through the output pipe 701, part of the fluid enters the lower outer shell 401 through the flow pipe 403, thereby applying pressure to the rubber diaphragm 504, which is opposite to the downward pressure of the pressure spring 503, thereby detecting the magnitude of the output pressure.
[0037] During the testing process, when the output pressure is greater than the downward pressure of the pressure spring 503, the pressure on the rubber diaphragm 504 increases, overcoming the downward pressure of the pressure spring 503 and moving upward. This causes the valve core 506 to move upward via the valve stem 505, bringing the valve core 506 closer to the through hole 101, reducing the fluid flow rate, and thus lowering the output pressure until it rebalances with the downward pressure of the spring. Conversely, when the output pressure is less than the downward pressure, the downward pressure pushes the rubber diaphragm 504 downward, and the valve core 506 moves away from the through hole 101, increasing the fluid flow rate, and thus raising the output pressure until it rebalances with the downward pressure of the spring.
[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
