Description

Technical Field

[0001] The utility model relates to the technical field of chillers, in particular to a chiller with liquid leakage protection. Background Art

[0002] With the rapid development of modern industrial and commercial activities, as an important cooling device, the chiller is widely used in various production and refrigeration processes. The chiller provides a stable cooling environment for the equipment by circulating cooling water, ensuring the continuity and efficiency of the production process. However, there are some technical defects in the existing chillers in practical applications. Especially at the connection between the inlet pipe and the external water pipe, due to reasons such as poor sealing or aging of the connecting parts, liquid leakage often occurs;

[0003] In the prior art, the liquid leakage protection measures of the chiller usually rely on manual inspection or simple alarm systems, which are prone to missing the tiny signs in the initial stage of liquid leakage. And when liquid leakage occurs, the operator needs to manually close the inlet valve, which not only increases the complexity of the operation but also prolongs the response time, and cannot achieve rapid and effective liquid leakage control. Therefore, a chiller with liquid leakage protection is proposed to overcome the above defects. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a chiller with liquid leakage protection. Through the floating plate and the ejector pin, the leaked liquid accumulates in the detection box, so that the floating plate drives the ejector pin to move and touch the switch to close the solenoid valve for liquid leakage protection, solving the problem that it is difficult for the chiller to quickly control liquid leakage.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model is a chiller with liquid leakage protection, including a chiller body. The bottom of the chiller body is penetrated by an inlet pipe. One end of the inlet pipe is provided with a water supply pipe. Flange plates are arranged at one ends of the inlet pipe and the water supply pipe. Clamping blocks are installed on one sides of the two flange plates. The flange plates are clamped with a sheath through the clamping blocks.

[0007] A detection box is installed on one side of the chiller body. Two guide rods are installed inside the detection box. A floating plate penetrates through the two guide rods. An ejector pin is installed in the middle of the floating plate. A switch is installed on the top of the detection box. A solenoid valve is arranged on the water supply pipe. The switch is electrically connected to the solenoid valve.

[0008] Preferably, an outlet pipe penetrates through the top of the chiller body. The two flange plates are connected by bolts.

[0009] Preferably, the inlet pipe and the water supply pipe penetrate through the detection box, and first sealing rings are arranged at the connection parts of the inlet pipe and the water supply pipe with the detection box.

[0010] Preferably, an observation window is provided on one side of the detection box, and a controller and an alarm are installed on the top of the detection box. The alarm, the switch and the controller are electrically connected.

[0011] Preferably, a clamping groove is formed on one side of the sheath, and the clamping block is clamped in the clamping groove.

[0012] Preferably, a second sealing ring is provided at the connection between the sheath and the flange.

[0013] The utility model has the following beneficial effects:

[0014] 1. Under the combined action of the floating plate and the ejector pin, when liquid leakage occurs between the water inlet pipe and the water supply pipe, the liquid causes the floating plate to move upward along the two guide rods, thereby driving the ejector pin to touch the switch to close the solenoid valve. Thus, it can prevent the liquid from continuing to flow into the main body of the chiller, achieving a rapid response to liquid leakage, cutting off the water source of the water supply pipe, quickly controlling the liquid leakage situation, avoiding the continuous occurrence and expansion of liquid leakage, effectively protecting against liquid leakage, and preventing the liquid leakage from directly flowing into the environment, avoiding direct damage to the equipment and the environment caused by liquid leakage, and improving the safety and reliability of the main body of the chiller;

[0015] 2. Under the combined action of the sheath and the second sealing ring, the clamping block is inserted into the clamping groove of the sheath to install the sheath. After liquid leakage occurs between the two flanges, the two sheaths protect the bolts on the flanges, effectively isolating the direct contact between the bolts and the liquid leakage, preventing the bolts from being corroded or damaged, thereby prolonging the service life of the bolts, reducing the possibility of their damage, protecting the flanges, and reducing the maintenance and replacement costs of the device.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Refer to Figures 1-4 , a liquid leakage protection chiller, including a chiller body 1. A water outlet pipe 101 penetrates through the top of the chiller body 1. Two flange plates 104 are connected by bolts. A water inlet pipe 102 penetrates through the bottom of the chiller body 1. The water inlet pipe 102 and a water supply pipe 103 penetrate through a detection box 2, and first sealing rings 202 are provided at the joints of the water inlet pipe 102 and the water supply pipe 103 with the detection box 2. By providing the two first sealing rings 202, the sealing performance of the joints of the water inlet pipe 102 and the water supply pipe 103 with the detection box 2 can be increased. One end of the water inlet pipe 102 is provided with a water supply pipe 103. Flange plates 104 are provided at one ends of the water inlet pipe 102 and the water supply pipe 103. Clamping blocks 8 are installed on one side of each of the two flange plates 104. The flange plates 104 are clamped with a sheath 9 through the clamping blocks 8. A clamping groove 901 is formed on one side of the sheath 9. The clamping blocks 8 are clamped in the clamping groove 901. By providing the clamping groove 901, the connection of the clamping blocks 8 can be facilitated. A second sealing ring 10 is provided at the joint of the sheath 9 and the flange plate 104. By providing the second sealing ring 10, the sealing performance of the joint of the sheath 9 and the flange plate 104 can be increased to protect the flange plates 104 and the bolts. When installing the two flange plates 104, move the sheath 9 towards the side close to the flange plate 104, so that the clamping blocks 8 are inserted into the clamping groove 901 of the sheath 9 to install the sheath 9, and the sealing performance between the sheath 9 and the flange plate 104 is increased through the second sealing ring 10. After liquid leakage occurs between the two flange plates 104, the bolts on the flange plates 104 are protected by the two sheaths 9, effectively isolating the direct contact between the bolts and the leaked liquid, and preventing the bolts from being corroded or damaged.

[0023] On one side of the chiller body 1, a detection box 2 is installed. On one side of the detection box 2, an observation window 201 is provided. The observation window 201 is made of transparent acrylic board. Through the set observation window 201, it is convenient to observe the liquid leakage in the detection box 2. On the top of the detection box 2, a controller 203 and an alarm 204 are installed. The alarm 204, the switch 6 and the controller 203 are electrically connected. When the ejector pin 5 touches the switch 6, the alarm 204 is turned on by the controller 203 to alert the staff. Inside the detection box 2, two guide rods 3 are installed. A floating plate 4 passes through the two guide rods 3. An ejector pin 5 is installed in the middle of the floating plate 4. A switch 6 is installed on the top of the detection box 2. A solenoid valve 7 is provided on the water supply pipe 103. The switch 6 is electrically connected to the solenoid valve 7. When liquid leakage occurs between the water inlet pipe 102 and the water supply pipe 103, the liquid flows from between the two flanges 104 into the detection box 2 for collection. When the liquid leakage increases, the floating plate 4 moves upward along the two guide rods 3, thereby driving the ejector pin 5 to touch the switch 6, causing the switch 6 to close the solenoid valve 7. Thus, it is possible to prevent the liquid from continuing to flow into the chiller body 1 from the water supply pipe 103, achieving a rapid response to liquid leakage and cutting off the water source of the water supply pipe 103, thereby quickly controlling the liquid leakage situation.
