Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to an automatic detection device for chilled water regulation. Background Art

[0002] In typical power station operations, the cooling supply for terminal equipment within large factory workshops has traditionally relied on chillers. This operation relies on manual adjustments to chilled water temperature and the number of chillers in operation, based on the terminal load generated by the number of devices operating within the workshop, to ensure proper operation of the equipment. However, seasonal changes and constant fluctuations in ambient temperature and humidity necessitate adjustments to chiller operating parameters. This requires frequent manual operation, which is both labor-intensive and places high demands on the operator's professional skills. Operators must possess extensive experience and precise judgment to make appropriate adjustments under complex and changing operating conditions. This requires high technical skills, and improper adjustments can easily cause downtime, halting all production lines in the workshop. Utility Model Content

[0003] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides an automatic detection device for chilled water regulation. The automatic detection device transmits the information of the medium flowing through the device to the controller in real time through the line. At the same time, the controller can collect the external ambient temperature and humidity, and automatically obtain a terminal load rate value based on the received medium information and the ambient temperature and humidity, and then feed it back to the external control system to control the temperature and flow of the cooling water to ensure the operating temperature of the processing equipment, avoid the processing equipment from being unable to cool and burning due to excessive temperature, and save manpower operation.

[0010] Preferably, a mounting plate is mounted on the sealed plate via a connecting column, the controller is mounted on the mounting plate, and a display screen is also provided on the controller.

[0011] Preferably, a support plate is installed on the sealing plate through connecting bolts, and the transmission rod passes through the support plate and the sealing plate respectively and is inserted into the valve pipe and remains threadedly connected to the support plate. A handwheel is provided on the end of the transmission rod outside the support plate.

[0012] Preferably, a central hole is provided on the transmission rod, and the circuit passes through the central hole.

[0029] As described in the background technology, the cooling supply of the terminal equipment in the existing power station usually needs to be adjusted according to the external environment and the number of terminal equipment. Currently, the adjustment is usually done manually, which is not only time-consuming and labor-intensive, but also requires high technical difficulty and operating experience. Otherwise, the terminal equipment will burn out due to untimely cooling.

[0030] For the reasons mentioned above, please refer to the attached Figure 1 ~Attached Figure 5 , the utility model provides an automatic detection device for chilled water regulation, comprising a valve pipe 1, both ends of which are connected to pipes 2;

[0031] The transmission rod 11 is movably provided on the valve pipe 1 and the opening of the valve in the valve pipe 1 is adjusted by rotating the transmission rod 11;

[0032] A controller 7 is disposed above the transmission rod 11 and communicates with an external control system;

[0033] A detection element is movably disposed in the valve pipeline 1 for detecting the fluid flowing in the valve pipeline 1, and the detection element is connected to the controller 7 via a line 9 preset in the transmission rod 11;

[0034] The controller 7 is also provided with a temperature sensor and a humidity sensor for collecting the external environment temperature and humidity.

[0035] Preferably, the valve pipe 1 is a three-way pipe, and its openings at both ends are respectively connected to the pipe 2 in a detachable sealed manner through flanges 3. A sealing plate 4 is movably connected to the other opening of the valve pipe 1, and the transmission rod 11 passes through the sealing plate 4 and is inserted into the valve pipe 1.

[0036] Preferably, a mounting plate 6 is mounted on the sealing plate 4 via a connecting column 5 , the controller 7 is mounted on the mounting plate 6 , and a display screen 8 is also provided on the controller 7 .

[0037] Preferably, a support plate 10 is mounted on the sealing plate 4 via connecting bolts, and the transmission rod 11 passes through the support plate 10 and the sealing plate 4 respectively and is inserted into the valve pipe 1 and remains threadedly connected to the support plate 10, and a handwheel 12 is provided on the end of the transmission rod 11 outside the support plate 10.

[0038] Preferably, a central hole is formed on the transmission rod 11, and the line 9 passes through the central hole.

[0039] Please combine the attached Figure 5 and attached Figure 6Preferably, a valve port is reserved in the valve pipe 1, and a connecting disc 13 and a valve flap 14 are respectively provided on the end of the transmission rod 11 inserted into the valve pipe 1. The valve flap 14 corresponds to the valve port of the valve pipe 1, and the connecting disc 13 is rotationally connected to the transmission rod 11. A slot 15 connected to the center hole of the transmission rod 11 is also provided on the connecting disc 13. The slot 15 is connected to the inside of the valve pipe 1, and the detection element is fixed in the slot 15 of the connecting disc 13.

[0040] Preferably, the detection elements are temperature sensors and flow sensors.

[0041] The external control system is connected to the chiller to control the outlet temperature and flow rate of the chilled water in the chiller so that the chilled water flows to the terminal equipment for cooling, thereby ensuring the normal operation of the terminal equipment.

[0042] Before using the device, the valve pipe 1 is fixed to the pipe 2 through the flange 3 with bolts, and the transmission rod 11 is simultaneously installed with a temperature sensor and a flow sensor.

[0043] During the test, the transmission rod 11 is rotated by turning the hand wheel 12. Since the transmission rod 11 is threadedly connected to the support plate 10, the transmission rod 11 can move up and down when rotating. When it rises, the valve disc 14 is separated from the valve port of the valve pipe 1, thereby opening the valve. The larger the distance between the valve disc 14 and the valve pipe 1, the larger the valve opening and the larger the flow rate that can pass through 9 (the valve opening is adjusted according to the number of terminal devices). The water of the terminal device flows from the pipe 2 into the valve pipe 1 and then passes through the valve port. A part of the water flows through the slot 15 and contacts the internal temperature sensor and flow sensor, thereby realizing real-time detection of the water of the terminal device. The detected temperature and flow information is fed back to the controller 7 through the line 9. The controller 7 automatically obtains a terminal load rate value based on the detected ambient temperature and humidity, the temperature and flow information of the water flowing through, and the number of terminal devices, and feeds this value back to the external control system. The outlet temperature and flow of the chilled water are adjusted according to the external control system to ensure that the terminal device is at a normal operating temperature and avoid the terminal device's cooling capacity demand being too large or too small. In different seasons and different ambient temperatures, the chiller works under the same working condition, which increases energy consumption. At the same time, it also consumes a lot of manpower to frequently operate and maintain the chiller.

[0044] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
