Ethylene glycol level control regulator

Abstract

This utility model discloses an ethylene glycol level control valve, comprising an ethylene glycol storage tank. A main pipeline is fixedly connected to the bottom of the storage tank. From left to right, a front manual valve, an adjustable valve, and a rear manual valve are sequentially bolted to the surface of the main pipeline. A motor is bolted to the top of the adjustable valve. This utility model uses a level sensor to monitor the liquid level in the ethylene glycol storage tank in real time and transmits the data to a display, allowing operators to intuitively understand the liquid level. When the liquid level changes, a remote control terminal can control the motor to operate according to received instructions from an external controller or a preset program. The motor drives a second gear to rotate, which in turn rotates a first gear meshing with the second gear, causing a rotating rod and a baffle to rotate, changing the opening of the adjustable valve, precisely controlling the flow rate of ethylene glycol, and achieving effective level regulation.

Description

Technical Field

[0001] This utility model relates to the field of ethylene glycol technology, specifically to an ethylene glycol level control and regulating valve. Background Technology

[0002] During the polymerization process, ethylene glycol, as a key raw material or auxiliary agent, needs to be stored in a dedicated storage tank. The liquid level of ethylene glycol in the storage tank must be maintained within a preset reasonable range to ensure the continuous stability of the subsequent polymerization reaction and avoid problems such as waste due to excessive liquid level or interruption of reaction due to excessive liquid level. However, existing ethylene glycol level control valves require manual adjustment on-site during actual use, which is labor-intensive, slow, and has poor flow rate control accuracy. Therefore, we propose an ethylene glycol level control valve. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a liquid level sensor to monitor the liquid level in an ethylene glycol storage tank in real time and transmits the data to a display, allowing operators to intuitively understand the liquid level within the tank.

When the liquid level changes, the remote control terminal 3 can control the motor 9 to operate according to the received external controller instructions or preset programs. The motor drives the second gear 11 to rotate, and the first gear 10 meshing with the second gear rotates accordingly, thereby causing the rotating rod 19 and the baffle 18 to rotate, changing the opening of the adjustable valve 12, precisely controlling the flow rate of ethylene glycol, and achieving effective regulation of the liquid level. Example 2

[0017] Please see Figure 1 and Figure 2The following technical solution is provided, specifically disclosing that: a battery box 16 is bolted to one side of an ethylene glycol storage tank 1; a storage battery 17 is bolted to the inner cavity of the battery box 16; a charging port 6 is provided at the middle of one side of the battery box 16; the output end of the charging port 6 is unidirectionally electrically connected to the input end of the storage battery 17; a buffer tank 14 is fixedly connected to the bottom of an adjustable valve 12 via a pipe; a buffer spring 21 is fixedly connected to the bottom of the inner cavity of the buffer tank 14; a buffer plate 20 is fixedly connected to the top of the buffer spring 21; and a buffer plate 20 is fixedly connected to the top of the buffer tank 14 via a pipe. The channel is connected to the main pipeline 7. A feed hopper 2 is fixedly connected to the middle of the top of the ethylene glycol storage tank 1. A cover plate is provided in the inner cavity of the feed hopper 2. Fixing rods 5 are fixedly connected to both sides of the top of the battery box 16. A display 4 is fixedly connected to the outside of the fixing rods 5. The input end of the display 4 is unidirectionally electrically connected to the output end of the liquid level sensor 15. A remote control terminal 3 is fixedly connected to the top of the ethylene glycol storage tank 1 by bolts. The output end of the remote control terminal 3 is unidirectionally electrically connected to the input end of the motor 9, and the input end of the remote control terminal 3 is unidirectionally electrically connected to the external controller. In actual use, the buffer device consists of the buffer box 14 at the bottom of the adjustable valve 12, the buffer spring 21, and the buffer plate 20. When the ethylene glycol flow rate suddenly changes or pressure fluctuations occur, the buffer plate 20 moves up and down under the action of the buffer spring 21 to absorb and buffer the pressure, reduce the impact on the adjustable valve and the main pipeline 7, extend the service life of the equipment, and reduce the probability of failure.

[0018] During use: Check that the cover of the feed hopper 2 is closed to ensure no foreign matter enters the ethylene glycol storage tank 1. Check that the pre-operated manual valve 8 and the post-operated manual valve 13 on the main pipeline 7 are in the appropriate open positions. Check that the battery 17 has sufficient power through the charging port 6 to ensure the emergency power supply system is normal. Check that the connections of the level sensor 15, display 4, remote control terminal 3, and motor 9 are secure and that communication is normal. The level sensor 15 monitors the liquid level in the ethylene glycol storage tank 1 in real time and transmits the liquid level data to the display 4 for display. The operator can observe the liquid level on the display, while the remote control terminal 3 receives the liquid level data and instructions from the external controller. When the liquid level needs to be adjusted, the remote control terminal 3 sends a control signal to the motor 9, which drives the second gear 11 to rotate. Through gear transmission, the first gear 10, the rotating rod 19, and the baffle 18 rotate, adjusting the opening of the adjustable valve 12 to control the flow rate of ethylene glycol, thereby achieving liquid level adjustment. During flow regulation, the buffer spring 21 and buffer plate 20 inside the buffer tank 14 buffer pressure fluctuations, protecting pipelines and valves. In the event of a power outage, the battery 17 automatically supplies power to devices such as the level sensor 15, display 4, remote control terminal 3, and motor 9, maintaining basic monitoring and control functions. When the automatic control malfunctions, operators can manually adjust the ethylene glycol flow rate by operating the pre-operated manual valve 8 and the post-operated manual valve 13 to ensure normal system operation. When it is necessary to stop the system, first turn off the control signal of the remote control terminal 3 to stop the operation of the motor 9. Then close the pre-operated manual valve 8 and the post-operated manual valve 13 to cut off the flow of ethylene glycol. Finally, check the status of the equipment to ensure there are no abnormalities, and then turn off the relevant power supply.
