Description

Technical Field

[0001] This utility model relates to the field of regulating valve technology, specifically a high-pressure resistant intelligent flow regulating device. Background Technology

[0002] Intelligent flow control devices are key equipment in high-pressure fluid transportation systems in fields such as petrochemicals and high-pressure water supply. They are mainly used to precisely control the fluid transportation flow rate and ensure the stability of the fluid transportation process. Their performance directly affects the operating efficiency and safety of the entire transportation system.

[0003] In the aforementioned high-pressure fluid transportation scenarios, existing intelligent flow regulation devices rely solely on conventional sealing gaskets for sealing at pipeline connections and lack adaptive high-pressure regulation capabilities. Furthermore, connections often depend on bolts and other fixed structures. Under continuous impact from high-pressure fluids, not only are loose connections prone to occur, but the integrity of the sealing structure is also compromised, leading to high-pressure fluid leakage. This makes it difficult to meet the requirements for sealing reliability and connection stability in high-pressure fluid transportation.

[0004] To address this issue, we propose a high-pressure resistant intelligent flow regulating device. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure resistant intelligent flow regulating device to solve the problems mentioned in the background art.

[0006] The technical solution of this utility model is as follows: a high-pressure resistant intelligent flow regulating device, comprising a flow pipe and an intelligent valve, wherein the intelligent valve is installed above the flow pipe and a control system is provided on the intelligent valve; mounting grooves are provided at both ends of the flow pipe, and several flow holes are provided on the inner ring wall of the mounting groove; an auxiliary sealing element is installed in each mounting groove, and several positioning elements are provided in the outer ring wall of each mounting groove; the auxiliary sealing element includes a sealing ring, which is disposed in the mounting groove, and the side wall of the inner end of the sealing ring is in contact with the side wall of the mounting groove; through the cooperation of the flow pipe mounting groove, flow holes and auxiliary sealing element, self-adaptive sealing can be achieved under high pressure, and the connection stability is enhanced by the positioning elements, thus meeting the sealing and connection requirements of high-pressure fluid transportation.

[0007] Preferably, the positioning element includes a positioning post, which is disposed inside the outer ring wall of the mounting groove. A component for cooperating with the positioning post is fixed on the sealing ring. The positioning post and the cooperating component on the sealing ring work together to achieve positioning synchronously when the sealing ring moves, further reinforcing the connection between the flow pipe and the pipeline and preventing the connection from loosening under high pressure.

[0008] Preferably, the components fixed on the sealing ring that cooperate with the movement of the positioning post include an inner push block and an outer push block. The inner push block is inserted into the side wall of the positioning post, and the outer push block is attached to one end of the positioning post located in the mounting groove. The inner push block restricts the initial position of the positioning post, and the outer push block pushes the positioning post out as the sealing ring moves, ensuring that the positioning post is accurately inserted into the pipe positioning hole and improving positioning reliability.

[0009] Preferably, the auxiliary sealing element further includes a first spring, which is disposed in the middle of the mounting groove and sleeved on the outside of the sealing ring. The first spring can apply a pre-tightening force to the sealing ring. Under high pressure, the auxiliary sealing ring presses the sealing gasket tightly, and under low pressure, it drives the sealing ring to reset, ensuring the sealing effect under different pressures.

[0010] Preferably, each end of the flow tube is provided with a warning element, which includes a mounting block, a moving block, a pressure block, and a pressure sensor. The mounting block is fixed to the outer wall of the flow tube, the moving block is disposed inside the mounting block with one end extending out of the end face of the flow tube, and the pressure block is fixed to the end of the moving block located inside the mounting block. The pressure sensor is fixed inside the mounting block and is aligned left and right with the pressure block. The pressure sensor is electrically connected to the control system of the smart valve. The pressure sensor senses the status of the moving block through the pressure block, and can monitor the tightness of the connection between the pipe and the flow tube in real time, and promptly transmit the loosening signal to the control system.

[0011] Preferably, the warning device further includes a second spring, which is disposed inside the mounting block and sleeved on the outside of the pressure block. One end of the second spring is attached to the moving block, and the other end is attached to the inner wall of the mounting block. The second spring applies an outward pushing force to the moving block. When the connection becomes loose, it quickly pushes the moving block to cause the pressure block to disengage from the pressure sensor, ensuring that the warning signal is triggered in a timely manner.

[0012] Preferably, the warning device also includes a buzzer, which is fixed on the outer wall of the mounting block and electrically connected to the control system of the intelligent valve. After receiving the signal from the control system, the buzzer sounds an alarm, which can intuitively remind the staff that the pipeline connection is loose, so as to facilitate timely maintenance and avoid high-pressure fluid leakage.

[0013] This utility model provides an improved intelligent flow regulating device that is resistant to high pressure. Compared with the prior art, it has the following improvements and advantages: Under high-pressure fluid transportation conditions, fluid is supplied through the flow hole in the inner ring wall of the flow pipe mounting groove. This pushes the sealing ring in the auxiliary sealing component to press the sealing gasket at the pipe connection, forming a tight sealing structure to prevent high-pressure fluid leakage. At the same time, the movement of the sealing ring can drive the positioning component to form a stable fit with the connecting pipe, avoiding loosening of the connection due to high pressure, further ensuring the sealing effect, and achieving reliable sealing and stable connection for fluid transportation under high pressure.

[0016] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0017] This utility model provides an improved intelligent flow regulating device resistant to high pressure. The technical solution of this utility model is as follows: like Figure 1 - Figure 4As shown, a high-pressure resistant intelligent flow regulating device includes a flow pipe 1 and an intelligent valve 2. The intelligent valve 2 is fixedly installed in the upper region of the flow pipe 1 and integrates a control system for signal reception, processing, and control execution. Annular mounting grooves 3 are respectively opened at both ends of the flow pipe 1. Several through-holes 5 are evenly distributed on the inner ring wall of the mounting groove 3. One end of each through-hole 5 communicates with the internal fluid channel of the flow pipe 1, and the other end communicates with the internal space of the mounting groove 3. An auxiliary seal is installed inside each mounting groove 3. Simultaneously, several receiving cavities are opened inside the outer ring wall of each mounting groove 3, and each receiving cavity is equipped with a... The auxiliary sealing element includes an annular sealing ring 4, which is fitted inside the mounting groove 3. The inner wall of the sealing ring 4 is tightly fitted with the inner ring wall of the mounting groove 3. The sealing ring 4 can move along the axial direction of the flow pipe 1 within the mounting groove 3. The control system of the intelligent valve 2 can realize intelligent adjustment of the fluid flow rate in the flow pipe 1. The mounting groove 3 provides installation space for the auxiliary sealing element and the positioning element. The flow hole 5 can introduce the high-pressure fluid in the flow pipe 1 into the mounting groove 3, pushing the sealing ring 4 to move. The fitting design between the sealing ring 4 and the inner ring wall of the mounting groove 3 can initially block the fluid leakage from the gap between the mounting groove 3 and the sealing ring 4, laying the foundation for subsequent high-pressure sealing.

[0018] The positioning component includes a columnar positioning post 7, which is fitted and installed in the receiving cavity of the outer ring wall of the mounting groove 3. The positioning post 7 can extend and retract within the receiving cavity along the radial direction of the flow pipe 1. A mating component for driving the positioning post 7 is fixed on the outer end sidewall of the sealing ring 4. This mating component is in corresponding contact with the inner end of the positioning post 7. The positioning post 7 can extend out of the receiving cavity under the action of the mating component and engage with the positioning hole on the connecting pipe. By driving the mating component to move through the sealing ring 4, the movement of the positioning post 7 and the sealing ring 4 can be linked, ensuring that the positioning is completed simultaneously while sealing, thus improving the structural coordination.

[0019] The mating components on the sealing ring 4 specifically include an inner push block 8 and an outer push block 9. Both the inner push block 8 and the outer push block 9 are fixedly connected to the outer side wall of the sealing ring 4, with the inner push block 8 located on the side of the outer push block 9 closest to the center of the sealing ring 4. The end of the inner push block 8 is inserted into the slot opened in the side wall of the positioning post 7, and the end face of the outer push block 9 is tightly fitted with the inner end face of the positioning post 7. In the initial state, the inner push block 8 restricts the extension and retraction of the positioning post 7 through the slot, preventing the positioning post 7 from moving arbitrarily. When the sealing ring 4 moves outward, the inner push block 8 moves with the sealing ring 4 and disengages from the slot, while the outer push block 9 simultaneously pushes the positioning post 7 outward, ensuring that the positioning post 7 extends accurately and is inserted into the pipe positioning hole, thereby achieving a stable connection between the flow pipe 1 and the pipe.

[0020] The auxiliary sealing component also includes an elastic first spring 6, which is sleeved on the outer wall of the sealing ring 4, and the installation position of the first spring 6 is located in the middle area of ​​the mounting groove 3. One end of the first spring 6 abuts against the bottom of the mounting groove 3, and the other end abuts against the outer end face of the sealing ring 4. In the initial state, the first spring 6 is in a pre-compressed state. The pre-compressed first spring 6 can apply a continuous pre-tightening force to the sealing ring 4, so that the sealing ring 4 always keeps in contact with the inner ring wall of the mounting groove 3, improving the initial sealing effect. When the high-pressure fluid pushes the sealing ring 4 to move outward, the first spring 6 is further compressed and stores elastic potential energy. When the fluid pressure decreases, the first spring 6 releases the elastic potential energy, driving the sealing ring 4 to reset, ensuring that the sealing ring 4 can effectively seal under different pressure conditions.

[0021] Each end of the flow tube 1 is equipped with a warning element, which includes a mounting block 10, a moving block 11, a pressure block 12, and a pressure sensor 13. The mounting block 10 is fixed to the outer wall of the flow tube 1 by welding or bolting, and has an axial receiving hole inside. The moving block 11 is adapted to be inserted into the receiving hole and can move axially along the receiving hole. One end of the moving block 11 extends out of the end face of the flow tube 1, and the other end is located inside the receiving hole. The pressure block 12 is a block structure and is fixedly connected to the end of the moving block 11 located inside the receiving hole. The pressure sensor 13 is fixedly installed in the receiving hole away from the moving block. On one side of the inner wall of the protruding end of 11, the sensing end face of the pressure sensor 13 is aligned with the end face of the pressure block 12, and the pressure sensor 13 is electrically connected to the control system of the intelligent valve 2 through a wire. When the flow pipe 1 is connected to the pipeline, the pipeline end face pushes the moving block 11 to move into the receiving hole. The pressure block 12 moves with the moving block 11 and squeezes the pressure sensor 13. The pressure sensor 13 transmits the pressure signal to the control system, indicating that the connection is in place. If the connection is loose, the moving block 11 moves outward, the pressure block 12 disengages from the pressure sensor 13, the pressure sensor 13 has no pressure signal output, and the control system can detect the loose connection in time.

[0022] The warning device also includes a flexible second spring 14, which is sleeved on the outer wall of the pressure block 12 and located in the receiving hole of the mounting block 10. One end of the second spring 14 abuts against the end face of the moving block 11 located inside the receiving hole, and the other end abuts against the stepped surface inside the receiving hole of the mounting block 10. In the initial state, the second spring 14 is in a compressed state. The compressed second spring 14 applies an outward elastic thrust to the moving block 11. When the flow pipe 1 is connected to the pipeline, the pressure on the pipeline end face overcomes the thrust of the second spring 14, keeping the moving block 11 in the receiving hole. If the connection is loose, the pressure of the pipeline on the moving block 11 decreases, and the thrust of the second spring 14 pushes the moving block 11 to move outward, ensuring that the pressure block 12 quickly disengages from the pressure sensor 13 and avoiding warning delay due to the lag in the movement of the moving block 11.

[0023] The warning device also includes a buzzer 15, which is fixed to the outer wall of the mounting block 10 by bolts or adhesive. The buzzer 15 is electrically connected to the control system of the smart valve 2 through wires, and can receive control signals sent by the control system and issue an audible alarm. When the pressure sensor 13 has no pressure signal output, the control system determines that the connection is loose and immediately sends an alarm signal to the buzzer 15. The buzzer 15 emits a clear sound to promptly remind the staff that the connection is loose, so that the staff can quickly locate the fault and carry out repairs, and avoid high-pressure fluid leakage due to failure to detect the looseness in time.

[0024] Working principle: First, during connection, connect the flow pipe 1 to the delivery pipe, that is, connect both ends of the flow pipe 1 to other pipes, and place a sealing gasket at the connection; when the pipe is connected to the flow pipe 1, press the moving block 11 inward, the moving block 11 moves the pressure block 12 inward until the pressure block 12 presses on the pressure sensor 13, the pressure sensor 13 transmits the pressure signal to the control system of the intelligent valve 2; when the connection becomes loose during use, the second spring 14 will push the moving block 11 outward, causing the moving block 11 to move outward, the moving block 11 drives the pressure block 12 to move, so that the pressure block 12 moves away from the pressure sensor 13. After the pressure sensor 13 does not sense the pressure signal, the control system controls the buzzer 15 to respond, reminding the staff to perform maintenance; In the second step, when the flow pipe 1 is under high pressure, the liquid being transported enters the installation groove 3 through the flow hole 5. Under pressure, the sealing ring 4 is pushed outward, and the sealing ring 4 presses against the sealing gasket at the connection point, forming a tight sealing ring body with the sealing gasket to prevent the high-pressure liquid from overflowing from the sealing gasket. When the sealing ring 4 moves outward, the inner push block 8 moves away from the positioning post 7, and the outer push block 9 pushes the positioning post 7, causing the positioning post 7 to protrude from the flow pipe 1 and be inserted into the positioning hole on the connected pipe, further fixing the flow pipe 1 to the pipe and preventing the connection from loosening when transporting high-pressure liquid, which would cause the sealing gasket to be unable to block the liquid from flowing out.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
