Description

Technical Field

[0001] This application relates to the technical field of pressure regulation, and in particular to a pressure stabilizing device and a compensation device. Background Technology

[0002] In equipment requiring pressurization, there are situations where pressure regulation is necessary. That is, when the pressure in a pressure zone decreases, it needs to be adjusted to maintain a stable pressure. Existing pressure stabilization devices mostly involve adding a pressure source, such as a pump, to regulate the pressure when it decreases. However, this process involves frequent pump starts, leading to a reduced lifespan. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, one of the objectives of this application is to provide a pressure stabilizing device and a compensation device, which has the advantages of being able to regulate pressure and reduce the probability of frequent pump starts.

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] A voltage stabilizing device includes a high-pressure zone, a low-pressure zone, and a regulating mechanism. When the pressure in the low-pressure zone decreases, the regulating mechanism moves under the pressure in the high-pressure zone, thereby connecting the low-pressure zone and the high-pressure zone.

[0006] By adopting the above technical solution, when the pressure in the low-pressure area decreases during use, the regulating mechanism moves, connecting the high-pressure area and the low-pressure area, thereby achieving the purpose of regulating the pressure in the low-pressure area.

[0007] In a preferred embodiment, the present application may be further configured such that: the adjusting mechanism includes a fixed cylinder, a sliding cylinder, and a pressure assembly; the sliding cylinder is partially located in the high-pressure zone and partially in the low-pressure zone; the sliding cylinder and the fixed cylinder are slidably connected; the sliding cylinder is provided with a through hole that communicates with the high-pressure zone; the pressure assembly is used to make the sliding cylinder tend to move toward the high-pressure zone; when the pressure in the low-pressure zone decreases, the sliding cylinder, under the action of the pressure in the high-pressure zone, overcomes the pressure of the pressure assembly and slides, thereby connecting the through hole with the low-pressure zone.

[0008] By adopting the above technical solution, when the pressure in the low-pressure zone decreases, the sliding cylinder overcomes the pressure of the pressure component under the pressure of the high-pressure zone, and slides, so that the through hole and the low-pressure zone are connected. This allows the pressure in the high-pressure zone to enter the low-pressure zone through the through hole, thereby replenishing the pressure in the low-pressure zone.

[0009] In a preferred embodiment, the application may be further configured such that the regulating mechanism also includes a pressure regulating component for regulating the pressure applied to the sliding cylinder by the pressure component.

[0010] By adopting the above technical solution, the trigger pressure can be adjusted according to the actual situation by adjusting the pressure applied to the sliding cylinder.

[0011] In a preferred embodiment, this application may be further configured such that: the pressure regulating component includes a movable member and an adjusting member, the adjusting member being used to adjust the relative position of the movable member and the sliding cylinder; and the pressure component includes an elastic member, one end of which is connected to the sliding cylinder and the other end of which is connected to the movable member.

[0012] By adopting the above technical solution, the relative position of the moving part and the sliding cylinder is adjusted, thereby changing the deformation of the elastic part, which in turn changes the force that needs to be overcome, thus achieving the purpose of adjusting the trigger pressure.

[0013] In a preferred embodiment, the present application may be further configured such that: the adjusting mechanism includes a fixed cylinder, a rotating cylinder and a pressure component, the rotating cylinder and the fixed cylinder are concentrically arranged and rotatably connected, the fixed cylinder is provided with a first hole that is connected to the high pressure zone, the rotating cylinder is provided with a second hole that is connected to the low pressure zone, and the pressure component drives the rotating cylinder to rotate under the action of the pressure difference between the high pressure zone and the low pressure zone, so that the first hole and the second hole are connected.

[0014] By adopting the above technical solution, that is, by rotating the cylinder, the connection between hole one and hole two is realized, thereby realizing the connection between the high pressure zone and the low pressure zone. The setting of the rotating cylinder also saves more space.

[0015] In a preferred embodiment, the present application may be further configured such that: the pressure assembly includes a power assembly and a transmission assembly, one end of the power assembly is in contact with the high-pressure area and the other end is in contact with the low-pressure area, and the transmission assembly includes a transmission rod, one end of which is fixedly connected to the power assembly and the other end is rotatably and slidably connected to the rotating cylinder.

[0016] By adopting the above technical solution, the pressure difference causes the transmission rod to move and drives the rotating cylinder to rotate.

[0017] In a preferred embodiment, the present application may be further configured such that: the power assembly includes a power pipe, a sliding member, an adjusting member, and a compression member; one end of the power pipe is connected to a low-pressure area, and the other end is connected to a high-pressure area; the sliding member slides within the power pipe and is fixedly connected at one end to a transmission rod; the compression member is located between the adjusting member and the sliding member, and the adjusting member is used to adjust the degree of deformation of the compression member.

[0018] By adopting the above technical solution, that is, by adjusting the degree of deformation of the compression component, the trigger pressure can be adjusted.

[0019] This application also discloses a compensation device: including the above-mentioned voltage stabilizing device, having multiple voltage stabilizing devices, which are used to connect multiple pressure regions, the pressure in the multiple pressure regions gradually decreases, and the low-pressure region of one voltage stabilizing device is connected to the high-pressure region of another voltage stabilizing device.

[0020] By adopting the above technical solution and setting up a pressure stabilizing device, pressure compensation can be achieved step by step.

[0021] In a preferred embodiment, the present application may be further configured such that: the voltage stabilizing device also includes a baffle and a flow plate, the flow plate is provided with a flow hole for connecting the low-pressure area and the high-pressure area, the baffle is connected to the regulating mechanism and is moved by the regulating mechanism.

[0022] By adopting the above technical solution, when the sliding cylinder moves, it will drive the baffle to move and block the flow hole. Therefore, while the current high pressure zone is compensating for the low pressure zone, it is also compensated by the higher pressure zone. The amount of compensation is greater than the amount of replenishment, thus realizing the compensation sequence from low to high.

[0023] In a preferred embodiment, this application can be further configured such that the baffle does not completely block the flow orifice.

[0024] This application has the following advantages:

[0025] The pressure stabilizing device reduces the dependence on electricity during pressure maintenance and avoids the problem of frequent pump starts during low flow operation;

[0026] The step-by-step compensation enables the water supply system to achieve dynamic balance, maintain stable water pressure, and avoid water hammer caused by excessive impact during compensation and user use.

[0027] The pressure regulating component allows for setting the differential pressure range to stabilize the differential pressure between different compensation chambers.

[0028] By setting baffles and flow holes, the compensation amount is greater than the replenishment amount, thus achieving a compensation sequence from low to high.

[0029] When the flow is limited, the flow orifice is not completely blocked. The flow limitation effectively prevents hydraulic shock caused by pressure changes between high-pressure and low-pressure areas, ensuring a smooth transition when switching between different states.

[0038] The present application will be further described in detail below with reference to the accompanying drawings.

[0039] Reference Figures 1-3 The present application discloses a pressure stabilizing device, embodiment 1, which includes a pressure-bearing pipe 1 and an adjusting mechanism 2. The adjusting mechanism 2 is installed inside the pressure-bearing pipe 1 and divides the pressure-bearing pipe 1 into a high-pressure zone 52 and a low-pressure zone 51. When the pressure in the low-pressure zone 51 decreases, the adjusting mechanism 2 moves under the pressure in the high-pressure zone 52, so that the low-pressure zone 51 and the high-pressure zone 52 are connected.

[0040] The regulating mechanism 2 includes a fixed cylinder 21, a sliding cylinder 22, and a pressure component 24. Due to the pressure difference between the high-pressure zone 52 and the low-pressure zone 51 and the presence of the pressure component 24, the sliding cylinder 22 can move or be fixed. The fixed cylinder 21 is fixedly connected to the pressure-bearing pipe 1, and the sliding cylinder 22 is slidably connected to the fixed cylinder 21. The sliding cylinder 22 includes a cylinder body 221 and a pressure plate 222. The pressure plate 222 is installed at one end of the cylinder body 221. The pressure plate 222 is located in the low-pressure zone 51, and the cylinder body 221 is located in the high-pressure zone 52. The cylinder body 221 is provided with a through hole 223. The pressure component 24 is used to make the sliding cylinder 22 tend to move towards the high-pressure zone 52. When the pressure in the low-pressure zone 51 decreases, the sliding cylinder 22 overcomes the pressure of the pressure component 24 under the pressure of the high-pressure zone 52, and slides, so that the through hole 223 is connected to the low-pressure zone 51.

[0041] The adjusting mechanism 2 also includes a pressure regulating component 23, which is used to regulate the pressure applied to the sliding cylinder 22 by the pressure component 24. The pressure regulating component 23 includes a movable part 231 and an adjusting part 232. The movable part 231 is a sliding ring, and the adjusting part 232 is an abutment rod. The pressure component 24 includes an elastic part 242 and a fixed ring 241. The fixed ring 241 is fixedly installed on the sliding cylinder 22, and the elastic part 242 is sleeved on the sliding cylinder 22. The sliding ring and the sliding cylinder 22 can slide relative to each other. The elastic part 242 is located between the fixed ring 241 and the sliding ring. In this embodiment, the elastic part 242 is a spring. The abutment rod can be a bolt, threadedly connected to the pressure-bearing pipe 1 and passing through the fixed cylinder 21, extending into the high-pressure zone 52. The sliding ring has a contact ramp located at the end of the sliding ring furthest from the elastic element 242, and the contact ramp contacts the abutment rod. Therefore, adjusting the distance the abutment rod extends into the high-pressure zone 52 allows for adjustment of the sliding ring's position, thereby adjusting the compression of the elastic element 242. In other embodiments, the abutment rod can be a bolt, which can be threadedly connected to the pressure-bearing pipe 1.

[0042] Example 2, refer to Figures 4-6 The regulating mechanism 2 includes a fixed cylinder 21, a rotating cylinder 25, and a pressure component 24. Due to the pressure difference between the high-pressure zone 52 and the low-pressure zone 51 and the presence of the pressure component 24, the rotating cylinder 25 can be moved or fixed. The fixed cylinder 21 is fixedly installed inside the pressure-bearing pipe 1. The rotating cylinder 25 and the fixed cylinder 21 are concentrically arranged and rotatably connected. The fixed cylinder 21 has a hole 261 that is connected to the high-pressure zone 52. The rotating cylinder 25 has a hole 262 that is connected to the low-pressure zone 51. The pressure component 24 drives the rotating cylinder 25 to rotate under the action of the pressure difference between the high-pressure zone 52 and the low-pressure zone 51, so that the hole 261 and the hole 262 are connected.

[0043] The pressure assembly 24 includes a power assembly and a transmission assembly. One end of the power assembly is in contact with the high-pressure zone 52, and the other end is in contact with the low-pressure zone 51. The power assembly includes a power pipe 271, a sliding member 274, an adjusting member 272, and a compression member 273. One end of the power pipe 271 is connected to the low-pressure zone 51, and the other end is connected to the high-pressure zone 52. The sliding member 274 slides within the power pipe 271. The compression member 273 is located between the adjusting member 272 and the sliding member 274. The adjusting member 272 is used to adjust the deformation degree of the compression member 273. In this embodiment, the adjusting member 272 can be a bolt, and the compression member 273 can be a spring, a rubber column, a silicone column, or other elastic object. In this embodiment, the fixed cylinder 21 and the rotating cylinder 25 can also be arc-shaped plates or other shapes, which can satisfy the requirement of switching between connection and disconnection between the high-pressure zone 52 and the low-pressure zone 51 after movement.

[0044] The transmission assembly includes a transmission rod 275, one end of which is fixedly connected to a slider 274, and the other end is rotatably and slidably connected to a rotating cylinder 25. A groove 276 is provided on the transmission rod 275 along its length. A fixing rod is provided on the rotating cylinder 25, located within the groove 276. The rotation angle of the fixing rod is less than 180 degrees, meaning the sliding point will not move to the extension line of the vertical movement of the slider 274.

[0045] Reference Figure 7 This application also discloses a compensation device employing the aforementioned voltage stabilizing device. Multiple voltage stabilizing devices are used to connect multiple pressure regions, with the pressure in each region gradually decreasing. The low-pressure region 51 of one voltage stabilizing device is connected to the high-pressure region 52 of another. For example, the multiple pressure regions may be a high-pressure chamber, a medium-pressure chamber, a low-pressure chamber, and a constant-pressure chamber, with the pressure decreasing sequentially. This is achieved by connecting the high-pressure chamber, medium-pressure chamber, low-pressure chamber, and constant-pressure chamber sequentially through three voltage stabilizing devices. When multiple voltage stabilizing devices are connected to form a compensation device, the high-pressure end of the voltage stabilizing device with the highest pressure is in a closed state. Figure 7 For example, the left end of the leftmost voltage regulator is in a closed state.

[0046] The pressure stabilizing device also includes a baffle 3 and a flow plate 4. The flow plate 4 is fixedly installed on the pressure-bearing pipe 1 or the fixed cylinder 21. The flow plate 4 has multiple flow holes 41. The flow plate 4 is positioned between the baffle 3 and the sliding cylinder 22. The baffle 3 is connected to the sliding cylinder 22 via a connecting rod 31 and is moved by the sliding cylinder 22. The connecting rod 31 passes through the flow plate 4. Both the flow plate 4 and the baffle 3 are positioned on the side of the sliding cylinder 22 away from the through hole 223. When the baffle 3 and the flow plate 4 come into contact, the baffle 3 partially blocks the flow holes 41. In other embodiments, the baffle 3 and the pressure-bearing plate 222 may be the same piece.

[0047] When using Embodiment 2, the baffle 3 is driven to rotate by the rotating cylinder 25, thereby blocking part of the flow hole 41.

[0048] The implementation principle of this embodiment is as follows: During use, when the pressure in the low-pressure zone 51 changes, the pressure plate 222 moves under the pressure in the high-pressure zone 52, thereby driving the cylinder to move, so that the through hole 223 is connected to the low-pressure zone 51, and then the high-pressure zone 52 is connected to the low-pressure zone 51, thereby realizing the pressure replenishment of the low-pressure zone 51.

[0049] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
