[0002] In equipment that needs to be pressurized, there are situations where the pressure needs to be adjusted. That is, when the pressure in the pressure zone decreases, the pressure in the pressure zone needs to be adjusted to keep the pressure in the pressure zone stable. Most existing pressure stabilizing devices increase the pressure source. For example, when the pressure in the pressure zone decreases, the pressure is adjusted through a pressure source, such as a pump. In this process, the pump is frequently started, resulting in a reduction in service life. Summary of the invention

[0003] In view of the deficiencies in the prior art, one of the purposes of the present application is to provide a pressure stabilizing device and a compensation device, which have the advantages of being able to adjust the pressure and reduce the probability of frequent pump startup.

[0004] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0005] A pressure stabilizing device comprises a high-pressure area, a low-pressure area and a regulating mechanism. When the pressure in the low-pressure area decreases, the regulating mechanism moves under the action of the pressure in the high-pressure area, so that the low-pressure area is connected with the high-pressure area.

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

The pressure assembly is used to make the sliding cylinder have a tendency to move toward the high-pressure area. When the pressure in the low-pressure area decreases, the sliding cylinder overcomes the pressure of the pressure assembly under the action of the pressure in the high-pressure area, slides, and connects the conducting hole to the low-pressure area.

[0012] By adopting the above technical solution, the relative positions of the movable member and the sliding cylinder are adjusted, so that the deformation of the elastic member is changed, and then the force to be overcome is changed, thereby achieving the purpose of adjusting the trigger pressure.

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

[0015] In a preferred example, the present application can be further configured as follows: the pressure component includes a power component and a transmission component, one end of the power component is in contact with the high-pressure area, and the other end is in contact with the low-pressure area, and the transmission component includes a transmission rod, one end of the transmission rod is fixedly connected to the power component, and the other end is rotatably and slidably connected to the rotating cylinder.

Therefore, while the current high-pressure area is compensating the pressure of the low-pressure area, it is also compensated by the higher-pressure area. The compensation amount is greater than the compensated supplement amount, realizing a compensation order from low to high.

[0023] In a preferred example, the present application can be further configured as follows: the baffle does not completely cover the flow hole.

[0027] The pressure regulating component can set the pressure difference range to stabilize the pressure difference between the compensation chambers at each level;

[0028] By setting the baffle and the flow hole, the compensation amount is greater than the compensated amount, so as to realize the compensation sequence from low to high;

[0029] The flow hole is not completely blocked during the compensation flow limiting, and the flow limiting can effectively prevent the sudden pressure change between the high-pressure area and the low-pressure area from causing hydraulic shock, ensuring a smooth transition when the states are switched freely.

DETAILED DESCRIPTION

[0038] The present application is further described in detail below in conjunction with the accompanying drawings.

[0039] Reference Figure 1-Figure 3 , is a pressure stabilizing device disclosed in the present application, embodiment 1, includes a pressure pipe 1 and an adjusting mechanism 2, the adjusting mechanism 2 is installed in the pressure pipe 1, and the pressure pipe 1 is divided into a high-pressure area 52 and a low-pressure area 51. When the pressure in the low-pressure area 51 decreases, the adjusting mechanism 2 moves under the action of the pressure in the high-pressure area 52, so that the low-pressure area 51 and the high-pressure area 52 are connected.

[0040] The regulating mechanism 2 includes a fixed cylinder 21, a sliding cylinder 22 and a pressure assembly 24. Due to the pressure difference between the high-pressure zone 52 and the low-pressure zone 51 and the existence of the pressure assembly 24, the sliding cylinder 22 can be moved or fixed. The fixed cylinder 21 is fixedly connected to the pressure 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. A conducting hole 223 is provided on the cylinder body 221. The pressure assembly 24 is used to make the sliding cylinder 22 have a tendency to move toward 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 assembly 24 under the action of the pressure in the high-pressure zone 52, and slides, so that the conducting hole 223 is connected to the low-pressure zone 51.

[0041] The regulating mechanism 2 further includes a pressure regulating assembly 23, which is used to regulate the pressure applied by the pressure assembly 24 on the sliding cylinder 22. The pressure regulating assembly 23 includes a movable member 231 and an adjusting member 232, wherein the movable member 231 is a sliding ring, and the adjusting member 232 is an abutting rod. The pressure assembly 24 includes an elastic member 242 and a fixed ring 241, wherein the fixed ring 241 is fixedly mounted on the sliding cylinder 22, and the elastic member 242 is sleeved on the sliding cylinder 22, wherein the sliding ring and the sliding cylinder 22 can slide relative to each other, and the elastic member 242 is located between the fixed ring 241 and the sliding ring. In this embodiment, the elastic member 242 is a spring. The abutment rod may be a bolt, which is threadedly connected to the pressure-bearing pipe 1 and passes through the fixing tube 21, and extends into the high-pressure area 52. The sliding ring is provided with a contact slope, which is located at the end of the sliding ring away from the elastic member 242. The contact slope contacts the abutment rod, so by adjusting the distance that the abutment rod extends into the high-pressure area 52, the position of the sliding ring can be adjusted, thereby adjusting the compression amount of the elastic member 242. In other embodiments, the abutment rod may be a bolt, which may be threadedly connected to the pressure-bearing pipe 1.

[0042] Example 2, reference Figure 4-Figure 6 The regulating mechanism 2 includes a fixed cylinder 21, a rotating cylinder 25 and a pressure assembly 24. Due to the pressure difference between the high-pressure zone 52 and the low-pressure zone 51 and the existence of the pressure assembly 24, the rotating cylinder 25 can be moved or fixed. The fixed cylinder 21 is fixedly installed in the pressure pipe 1. The rotating cylinder 25 and the fixed cylinder 21 are concentrically arranged and rotatably connected. A hole 261 is provided on the fixed cylinder 21, and the hole 261 is connected to the high-pressure zone 52. A hole 262 is provided on the rotating cylinder 25, and the hole 262 is connected to the low-pressure zone 51. The pressure assembly 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 is connected to the hole 262.

[0043] The pressure assembly 24 includes a power assembly and a transmission assembly. One end of the power assembly contacts the high-pressure zone 52, and the other end contacts the low-pressure zone 51. The power assembly includes a power tube 271, a sliding member 274, an adjusting member 272, and a compression member 273. One end of the power tube 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 in the power tube 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 or an elastic object such as a rubber column or a silicone column. In this embodiment, the fixed cylinder 21 and the rotating cylinder 25 can also be an arc plate, or other shapes, which can satisfy the switching between the high-pressure zone 52 and the low-pressure zone 51 between connection and disconnection after movement.

[0044] The transmission assembly includes a transmission rod 275, one end of which is fixedly connected to the sliding member 274, and the other end is rotatably and slidably connected to the rotating cylinder 25. The transmission rod 275 is provided with a slide groove 276, which is arranged along the length direction of the transmission rod 275. The rotating cylinder 25 is provided with a fixed rod, which is located in the slide groove 276. The rotation angle of the fixed rod is less than 180 degrees, that is, the sliding point will not move to the extension line of the sliding member 274 moving up and down.

[0045] Reference Figure 7 The present application also discloses a compensation device, which adopts the above-mentioned voltage-stabilizing device. There are multiple voltage-stabilizing devices, and the multiple voltage-stabilizing devices are used to connect multiple pressure areas. The pressures of the multiple pressure areas gradually decrease, and the low-pressure area 51 of one voltage-stabilizing device is connected to the high-pressure area 52 of another voltage-stabilizing device. For example, the multiple pressure areas are respectively a high-pressure chamber, a medium-pressure chamber, a low-pressure chamber and a constant-pressure chamber, and the pressures decrease in sequence, that is, the high-pressure chamber, the medium-pressure chamber, the low-pressure chamber and the constant-pressure chamber are connected in sequence through three voltage-stabilizing devices. When multiple voltage-stabilizing devices are connected to form a compensation device, one side of the high-pressure end of the voltage-stabilizing device corresponding to the highest pressure is in a closed state, so that the high-pressure chamber, the medium-pressure chamber, the low-pressure chamber and the constant-pressure chamber are connected in sequence. Figure 7 For example, the left end of the leftmost voltage stabilizing device 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 mounted on the pressure pipe 1 or the fixed cylinder 21. The flow plate 4 is provided with a flow hole 41. There are multiple flow holes 41. The flow plate 4 is arranged between the baffle 3 and the sliding cylinder 22. The baffle 3 is connected to the sliding cylinder 22 through a connecting rod 31 and is driven to move by the sliding cylinder 22. The connecting rod 31 passes through the flow plate 4. The flow plate 4 and the baffle 3 are both arranged on the side of the sliding cylinder 22 away from the conducting hole 223. When the baffle 3 and the flow plate 4 are in contact, the baffle 3 blocks part of the flow hole 41. In other embodiments, the baffle 3 and the pressure plate 222 may be the same piece.

[0047] When the second embodiment is adopted, the baffle 3 is driven to rotate by the rotating cylinder 25 , thereby partially shielding the flow holes 41 .

[0048] The implementation principle of this embodiment is: during use, when the pressure in the low-pressure area 51 changes, the pressure plate 222 moves under the action of the pressure in the high-pressure area 52, thereby driving the cylinder to move, so that the conducting hole 223 and the low-pressure area 51 are connected, and then the high-pressure area 52 and the low-pressure area 51 are connected, thereby achieving pressure compensation for the low-pressure area 51.

[0049] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
