Description

Technical Field

[0001] This utility model relates to the field of pressure gauge technology, and in particular to an intelligent pressure controller. Background Technology

[0002] Digital pressure gauges are high-precision pressure gauges that integrate pressure measurement and display. They feature vibration resistance, high display accuracy, high stability, zeroing capability, and automatic standby. This series of digital pressure gauges is battery-powered and, thanks to its low-power processor chip, boasts a long battery life. It also features automatic standby and one-button zeroing functions, making it easy to use. It can replace mechanical pressure gauges in various fields such as portable pressure measurement, equipment integration, and standard pressure calibration equipment.

[0003] Existing intelligent pressure controllers have a wide range of applications, but their installation and disassembly efficiency is low when connected to pipelines. Each installation or disassembly requires the use of tools such as wrenches, pipe wrenches, and welding guns, as well as complex operations such as wrapping PTFE tape, applying sealant, centering, tightening, or cutting / welding, which slows down the overall installation efficiency. At the same time, the sealing effect is affected by the operator's experience (such as improper wrapping of PTFE tape or uneven tightening torque), which can easily lead to leakage due to human error and cause irreversible damage. In view of this, an intelligent pressure controller is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as low installation and disassembly efficiency when connecting to pipelines, and the fact that the sealing effect is affected by the operator's experience, making it prone to leakage due to human error and causing irreversible damage. Therefore, an intelligent pressure controller is proposed.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A smart pressure controller includes a smart pressure gauge, a switching valve is provided at the bottom of the smart pressure gauge, and a quick-connect assembly is fixedly provided at the bottom of the switching valve.

[0007] The quick-connect component includes;

[0008] A sealed housing, which is fixedly installed at the bottom of the switching valve;

[0009] Conveying column; the conveying column is disposed inside the sealed housing and is connected to the internal space of the switching valve;

[0010] A fixing ring is fixedly disposed at the top of the inner cavity of the sealing shell, and a clamping block is fixedly disposed at the bottom of the fixing ring. The clamping blocks are arranged in a ring array about the axis of the fixing ring, and a rotating arm is rotatably disposed at the bottom of the clamping block, and a clamping end is disposed at the other end of the rotating arm.

[0011] A drive ring is disposed on the upper surface of the clamping end, and the inner wall of the drive ring slides in contact with it.

[0012] Preferably, a support column is fixedly provided at the bottom of the fixed ring, the support columns are arranged in a ring array about the axis of the fixed ring, and a connecting ring is slidably provided on the outer wall of the support column, and the inner side of the connecting ring is fixedly provided with the drive ring.

[0013] Preferably, the outer wall of the support column is provided with an elastic element, and the two ends of the elastic element abut against the connecting ring and the fixing ring respectively.

[0014] Preferably, a sliding groove is provided on the outer wall of the sealing shell near the bottom, and the sliding groove is arranged in a ring array about the outer axis of the sealing shell, and a telescopic block is slidably arranged inside the sliding groove.

[0015] Preferably, the inner wall of the telescopic block is provided with a sealing plate, and the inner side of the sealing plate is in contact with the conveying column when the moving path reaches its maximum value.

[0016] Preferably, the outer wall of the sealing shell is provided with a threaded groove near the bottom, and a reinforcing nut is rotatably provided on the outer wall of the threaded groove, with the inner side of the reinforcing nut fitting against the outer side of the telescopic block.

[0018] Preferably, the drive ring, telescopic block, and sealing plate are all made of rubber.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: After the pipe is inserted into the conveying column, the wall thickness of the pipe contacts the drive ring. The force of the pipe extending inward forces the drive ring to move backward. At the same time, the rotating arm set at the bottom of the drive ring rotates with the drive ring, reducing the shaft size, so that the clamping end can clamp the pipe and prevent it from falling off. Then, the reinforcing nut is rotated to push the sealing plate on the inner wall of the telescopic block to seal the pipe.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Example: This example provides an intelligent pressure controller, see [link to example]. Figure 1-5 Specifically, it includes a smart pressure gauge 1, a switch valve 11 is provided at the bottom of the smart pressure gauge 1, and a quick-connect assembly 2 is fixedly provided at the bottom of the switch valve 11.

[0031] Quick-connect component 2 includes;

[0032] A sealing housing 21 is fixedly installed at the bottom of the switch valve 11.

[0033] Conveying column 22; The conveying column 22 is disposed inside the sealed housing 21 and is connected to the internal space of the switching valve 11;

[0034] A fixing ring 24 is fixedly disposed at the top of the inner cavity of the sealing shell 21, and a clamping block 241 is fixedly disposed at the bottom of the fixing ring 24. The clamping blocks 241 are arranged in a ring array about the axis of the fixing ring 24, and a rotating arm 242 is rotatably disposed at the bottom of the clamping block 241. A clamping end 244 is disposed at the other end of the rotating arm 242.

[0035] Drive ring 246 is disposed on the upper surface of clamping end 244, and the inner wall of drive ring 246 slides against it.

[0036] In this optional embodiment, after the pipe is inserted into the delivery column 22, the wall thickness of the pipe contacts the drive ring 246. The force of the pipe extending inward forces the drive ring 246 to move backward. At the same time, the rotating arm 242 at the bottom of the drive ring 246 rotates with the drive ring 246, reducing the shaft size, so that the clamping end 244 can clamp the pipe, preventing the pipe from falling off, reducing the installation steps between the pipe and the pressure gauge, and improving the installation efficiency.

[0037] Optionally, a support column 245 is fixedly provided at the bottom of the fixed ring 24. The support columns 245 are arranged in a ring array about the axis of the fixed ring 24, and a connecting ring 247 is slidably provided on the outer wall of the support column 245. The inner side of the connecting ring 247 is fixedly provided with the drive ring 246.

[0038] In this optional embodiment, multiple connecting rings 247 are used to connect the drive ring 246, so that when the drive ring 246 is pushed by the wall thickness of the pipe, the connecting rings 247 slide on the outer wall of the support 245 to prevent the drive ring 246 from shifting.

[0039] Optionally, the outer wall of the support column 245 is provided with an elastic element 243, and the two ends of the elastic element 243 abut against the connecting ring 247 and the fixing ring 24 respectively;

[0040] In this optional embodiment, an elastic element 243 is provided between the connecting ring 247 and the fixed ring 24, which can reduce the buffering of the sliding of the connecting ring 247. At the same time, after the connection with the pipe is canceled, the elastic element 243 can push the connecting ring 247 to drive the driving ring 246 back to the initial position, which facilitates the next connection.

[0041] Optionally, a sliding groove 212 is provided on the outer wall of the sealing housing 21 near the bottom, and the sliding groove 212 is arranged in a ring array about the outer axis of the sealing housing 21. A telescopic block 25 is slidably arranged inside the sliding groove 212.

[0042] In this optional embodiment, the telescopic block 25 slides inside the sliding groove 212. After the pipe is inserted, the telescopic block 25 retracts inward to reduce the axial size and clamp the pipe, preventing the risk of it falling off and leaking.

[0043] Optionally, a sealing plate 252 is provided on the inner wall of the telescopic block 25, and the inner side of the sealing plate 252 is in contact with the conveying column 22 when the moving path reaches the maximum value.

[0044] In this optional embodiment, when the telescopic block 25 retracts inward, the sealing plate 252 retracts inward and adheres to the outer wall of the pipe. As the telescopic block 25 continues to retract inward, multiple sealing plates 252 can be assembled into a ring shape. The ring-shaped sealing plate 252 adheres to the outer wall of the pipe, improving the sealing performance and increasing its stability.

[0045] Optionally, a threaded groove 211 is provided on the outer wall of the sealing housing 21 near the bottom, and a reinforcing nut 23 is rotatably provided on the outer wall of the threaded groove 211, with the inner side of the reinforcing nut 23 fitting against the outer side of the telescopic block 25.

[0046] In this optional embodiment, the telescopic block 25 is driven to retract inward by rotating the reinforcing nut 23, while the self-locking property between the threads is used to improve the stability of the pipe connection.

[0047] Optionally, the upper outer side of the telescopic block 25 is provided with an inclined surface 251, and the lowest end of the inclined surface 251 is provided inside the reinforcing nut 23.

[0048] In this optional embodiment, since the upper end of the telescopic block 25 is provided with an inclined surface 251, when the reinforcing nut 23 rotates on the outer wall of the threaded groove 211, it contacts the inclined surface 251, thereby driving the telescopic block 25 to slide parallel inside the moving groove, reducing the jamming situation.

[0049] Optionally, the drive ring 246, the telescopic block 25, and the sealing plate 252 are all made of rubber.

[0050] In this optional embodiment, since the drive ring 246, the telescopic block 25 and the sealing plate 252 are all made of rubber, their plasticity is greatly improved, and the sealing between the pipeline and the pressure gauge can also be effectively improved.

[0051] 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.
