Description

Technical Field

[0001] This utility model relates to the field of mechanical seals, and more specifically, to a PLAN52 system with a root valve and dual pressure tapping. Background Technology

[0002] In industrial production, mechanical seals, as an important sealing device, are widely used in rotating equipment such as pumps, compressors, and reactors. They are primarily used to prevent media leakage, ensuring normal equipment operation and environmental safety. Currently, traditional mechanical seal flushing systems (such as PLAN52) are widely adopted. Their main function is to maintain the lubrication, cooling, and pressure stability of the seals through a buffer solution circulation system. In the PLAN52 system, the buffer solution circulates between the sealing rings, and pressure control ensures the normal flow of the buffer solution, preventing leakage. However, the traditional PLAN52 system still has the following drawbacks:

[0003] Traditional PLAN52 systems are relatively simple in terms of pressure monitoring, typically using only one pressure tap. This fails to comprehensively reflect pressure changes in the buffer solution throughout the system, limiting precise adjustment and effective management. The lack of multiple pressure taps makes it difficult to simultaneously monitor the pressure difference between the buffer supply and return ends, potentially leading to system pressure instability and even affecting the sealing performance of the mechanical seal. Excessive or insufficient pressure can cause seal failure or media leakage. Therefore, a dual-pressure-tapping PLAN52 system with a root valve is proposed. Utility Model Content

[0004] The purpose of this invention is to address the fact that the existing PLAN52 system is relatively simple in terms of pressure monitoring, usually with only one pressure tap, which cannot fully reflect the pressure changes of the buffer solution throughout the system. This design limits the precise adjustment and effective management of the buffer solution system. Since there are no multiple pressure taps, it is difficult to monitor the pressure difference between the buffer solution supply end and the return end at the same time, which may lead to unstable system pressure and even affect the sealing effect of the mechanical seal. Excessive or insufficient pressure may lead to seal failure or media leakage.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] The present invention is as follows: a PLAN52 system with a root valve and dual pressure tapping, including a sealing tank, wherein a first connecting pipe and a second connecting pipe are respectively connected to the top and bottom of the sealing tank, and a root valve is provided on the outside of both the first connecting pipe and the second connecting pipe. A connecting pipe is connected to the outside of the first connecting pipe, and a pressure transmitter and a pressure gauge are respectively provided at both ends of the connecting pipe.

[0007] As a preferred technical solution of this utility model, a straight pipe is connected to the outer wall of the sealing liquid tank, a liquid level transmitter is provided outside the straight pipe, a bent pipe is provided on the top outer wall of the sealing liquid tank, and a threaded cap funnel is connected to the top of the bent pipe.

[0008] As a preferred technical solution of this utility model, a five-valve assembly is provided on the outer wall of the straight pipe, and the five-valve assembly is used in conjunction with two root valves.

[0009] As a preferred technical solution of this utility model, a dual-channel gauge valve is provided on the outer wall of both ends of the connecting pipe.

[0010] As a preferred technical solution of this utility model, the liquid level transmitter is provided with an armored explosion-proof gland.

[0011] As a preferred technical solution of this utility model, a raised plate is provided on the outer wall of the sealing liquid tank.

[0012] As a preferred technical solution of this utility model, a support frame is fixedly connected to the outer wall of the sealing tank, an mounting plate is fixedly connected to the bottom of the support frame, and a pull rod type controller is fixedly connected to the outer wall of the support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Through the set first connecting pipe, second connecting pipe, root valve, connecting pipe, pressure transmitter, and pressure gauge, pressure data can be obtained from different positions of the device during use via the two root valves. The two root valves provide two pressure taps, which are used to monitor the pressure of the buffer solution at different positions in the device. One of these pressure taps is located in the first connecting pipe, and the other is located in the second connecting pipe. Through these two pressure taps, the supply pressure and return pressure of the buffer solution can be monitored separately, thereby controlling and adjusting the device more accurately. The pressure transmitter and pressure gauge are used to monitor the pressure of the buffer solution inside the sealing tank in real time, ensuring that the pressure of the device is within the normal range. The operator can obtain real-time feedback so as to adjust the pressure and liquid level in a timely manner.

[0015] 2. The liquid level transmitter is used to detect the liquid level in the sealing tank through the set straight pipe, liquid level transmitter, bend pipe and threaded cap funnel. The liquid level transmitter is used to detect the liquid level in the sealing tank to prevent the liquid level from being too low or too high, which would cause the seal to fail. The threaded cap funnel can help the sealing tank maintain an appropriate liquid level to ensure a continuous supply of buffer solution. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0022] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] like Figure 1As shown, this embodiment proposes a PLAN52 system with root valves and dual pressure taps, including a sealing tank 1. A first connecting pipe 2 and a second connecting pipe 3 are respectively connected to the top and bottom of the sealing tank 1. Root valves 4 are installed outside both the first and second connecting pipes 2 and 3. A connecting pipe 5 is connected to the outside of the first connecting pipe 2. A pressure transmitter 6 and a pressure gauge 7 are respectively installed at both ends of the connecting pipe 5. In use, pressure data can be obtained from different positions of the device through the two root valves 4. The two root valves 4 provide two pressure taps, which are used to monitor the pressure of the buffer solution at different positions in the device. One of these pressure taps is located in the first connecting pipe 2, and the other is located in the second connecting pipe 3. Through these two pressure taps, the supply pressure and return pressure of the buffer solution can be monitored respectively, thereby more accurately controlling and adjusting the device. The pressure transmitter 6 and the pressure gauge 7 are used to monitor the pressure of the buffer solution inside the sealing tank 1 in real time, ensuring that the pressure of the device is within the normal range. The operator can obtain real-time feedback to adjust the pressure and liquid level in a timely manner.

[0026] like Figure 4 As shown, a straight pipe 8 is connected to the outer wall of the sealing liquid tank 1, and a level transmitter 9 is installed outside the straight pipe 8. A bend pipe 10 is installed on the top outer wall of the sealing liquid tank 1, and a threaded cap funnel 11 is connected to the top of the bend pipe 10. In use, the level transmitter 9 is used to detect the liquid level in the sealing liquid tank 1 to prevent the seal from failing due to the liquid level being too low or too high. The threaded cap funnel 11 can help the sealing liquid tank 1 maintain an appropriate liquid level to ensure a continuous supply of buffer solution.

[0027] like Figure 1 As shown, a five-valve assembly 12 is provided on the outer wall of the straight pipe 8. The five-valve assembly 12 works in conjunction with two root valves 4. When in use, the five-valve assembly 12 provides a multi-functional control method to regulate the liquid flow direction and pressure, and provides multiple flow paths to adapt to different measurement and regulation needs.

[0028] like Figure 1 As shown, dual-channel gauge valves 13 are installed on the outer walls of both ends of the connecting pipe 5. One dual-channel gauge valve 13 is located between the pressure transmitter 6 and the connecting pipe 5, and the other dual-channel gauge valve 13 is located between the end of the connecting pipe 5 away from the pressure transmitter 6 and the pressure gauge 7. Two different pressure measurement points can be connected through the dual-channel gauge valves 13 to ensure that the system can obtain the two-point pressure information of the buffer solution in real time.

[0029] like Figure 1 As shown, the liquid level transmitter 9 is externally equipped with an armored explosion-proof gland 14. The armored explosion-proof gland 14 serves to protect the liquid level transmitter 9 and prevent leakage or electrical faults from affecting the liquid level transmitter 9.

[0030] like Figure 2As shown, a raised plate 15 is provided on the outer wall of the sealing liquid tank 1. When in use, a warning sticker can be affixed to the raised plate 15 to warn unauthorized personnel to stay away from the device.

[0031] like Figure 2 As shown, a support frame 16 is fixedly connected to the outer wall of the sealing liquid tank 1, and an mounting plate 17 is fixedly connected to the bottom of the support frame 16. A pull rod controller 18 is fixedly connected to the outer wall of the support frame 16. In use, the device can be supported by the support frame 16, and the device can be fixed by screwing external bolts into the round holes on the mounting plate 17 and the ground. The pull rod controller 18 can control the opening and closing of the device, thereby improving safety.

[0032] Specifically, in use, the PLAN52 system with dual pressure taps and root valves allows pressure data to be acquired from different locations within the device via two root valves 4. These two valves provide two pressure taps, one located in the first connecting pipe 2 and the other in the second connecting pipe 3. Through these two taps, the supply and return pressures of the buffer solution can be monitored separately, thereby enabling more accurate control and adjustment of the device (e.g., ...). Figure 1 and Figure 4 As shown), pressure transmitter 6 and pressure gauge 7 are used to monitor the pressure of the buffer solution inside sealing tank 1 in real time, ensuring that the pressure of the device is within the normal range. The operator can obtain real-time feedback so as to adjust the pressure and liquid level in a timely manner (e.g., Figure 4 As shown), the level transmitter 9 is used to detect the liquid level in the sealing tank 1 to prevent the seal from failing due to excessively low or high liquid levels (e.g., ...). Figure 1 As shown), the threaded cap funnel 11 helps the sealing tank 1 maintain an appropriate liquid level, ensuring a continuous supply of buffer solution (e.g., Figure 4 As shown), the dual-channel gauge valve 13 can then connect to two different pressure measurement points, ensuring that the system can obtain the two-point pressure information of the buffer solution in real time (e.g., Figure 1 and Figure 4 (As shown).

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
