Description

Technical Field

[0001] The utility model relates to the field of chillers, and particularly to chiller units. Background Art

[0002] A chiller unit is an industrial temperature control device that uses air-cooled or water-cooled cooling methods to adjust the device temperature. The chiller unit is the "refrigeration source" of the central air conditioner, sending circulating water to each room and reducing its temperature to "cooling water". Chiller units have different types such as air-cooled, water-cooled, cold storage, and ice storage types, each with its own advantages, disadvantages, and applicable scenarios. In the refrigeration industry, chiller units are mainly divided into two types: air-cooled chiller units and water-cooled chiller units; according to different compressors, they can also be divided into screw chiller units, scroll chiller units, and centrifugal chiller units.

[0003] The circulating water and circulating makeup water used by chiller units need to meet certain water quality requirements. When the water quality does not meet the standard, it may cause scaling or corrosion. Therefore, it is necessary to regularly inspect the water quality of chiller units. During the inspection, circulating water is usually collected from the chiller unit pipeline for detection. Since there is a certain water pressure in the pipeline, it is necessary to first control the chiller unit to stop before conducting the water quality detection, which is rather troublesome.

[0004] Therefore, it is necessary to provide a chiller unit to solve the above technical problems. Content of the Utility Model

[0022] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] Please refer to Figures 1 to 6The chiller of the utility model comprises a chiller body 1, on which a circulating water inlet 102 and a circulating water outlet 101 are arranged, a sample storage cylinder 2 is arranged below the circulating water outlet 101, a water outlet 9 is arranged at the bottom of the outer wall of the sample storage cylinder 2, a sampling cylinder 3 is arranged at the top of the sample storage cylinder 2, the top of the sampling cylinder 3 extends into the circulating water outlet 101, a plurality of sampling holes 301 are provided at the part where the sampling cylinder 3 extends into the circulating water outlet 101, and a first sampling hole 301 is slidably installed inside the sample storage cylinder 2 Piston 4, an adjusting component for adjusting the position of the first piston 4 is arranged below the first piston 4, a connecting rod 5 is fixedly installed on the top of the first piston 4, a sealing disk 6 is fixedly installed on the top of the connecting rod 5, the sealing disk 6 is slidably installed in the sampling tube 3, a retaining ring 302 is fixedly installed inside the sampling tube 3, when the first piston 4 moves to the bottom of the inner cavity of the sample storage tube 2, the bottom wall of the sealing disk 6 is pressed on the top wall of the retaining ring 302, a sealing ring is arranged at the bottom of the retaining ring 302, and all the sampling holes 301 are located above the retaining ring 302. When it is necessary to collect circulating water for testing, the first piston 4 is moved downward by adjusting the assembly, so that the circulating water in the circulating water outlet 101 enters the sampling tube 3 through the sampling hole 301 and enters the sample storage tube 2. When the first piston 4 moves to the bottom of the inner cavity of the sample storage tube 2, the bottom wall of the sealing disk 6 is pressed on the top wall of the retaining ring 302. At this time, the sampling tube 3 is blocked by the sealing disk 6 at the position of the retaining ring 302, so that the water in the circulating water outlet 101 cannot continue to enter the sample storage tube 2 through the sampling tube 3. Then the water outlet 9 can be opened to discharge the collected water sample and collect it through the container, so as to realize the collection of the water sample. During the sampling process, the circulating water outlet 101 is always not connected to the outside world, so that the operation of the chiller during the sampling process will not be affected. Therefore, the chiller can also be sampled during operation, and sampling detection is more convenient, and the influence of the external environment on the circulating water can be effectively avoided. Moreover, during the sampling process, the circulating water is in a flowing state, and the circulating water at various locations can be collected. The sampling is relatively uniform, which can improve the uniformity of sampling.

[0024] The bottom end of the circulating water outlet 101 is connected to a pressure regulating cylinder 13, in which a second piston 14 is slidably installed, and a second screw 15 is rotatably installed at the bottom end of the second piston 14. The second screw 15 penetrates the bottom wall of the pressure regulating cylinder 13, and the second screw 15 is threadedly connected to the bottom wall of the pressure regulating cylinder 13. A second knob 16 is fixedly installed at the bottom end of the second screw 15 to facilitate the rotation of the second screw 15. The bottom wall of the pressure regulating cylinder 13 is provided with an exhaust hole to discharge the gas below the second piston 14 in the pressure regulating cylinder 13. When the first piston 4 moves downward, the second screw 15 is rotated at the same time to move the second piston 14 upward, thereby balancing the hydraulic pressure of the circulating water to prevent the hydraulic pressure of the circulating water from being too low.

[0025] In this embodiment, preferably, Figures 4 - 5As shown in the figure, the adjusting assembly includes a first screw rod 7 and a first knob 8. The top end of the first screw rod 7 is rotatably connected to the first piston 4, and the bottom end of the first screw rod 7 is fixedly connected to the first knob 8. The first screw rod 7 penetrates through the bottom wall of the sample storage cylinder 2, and the first screw rod 7 is threadedly connected to the bottom wall of the sample storage cylinder 2. By rotating the first knob 8, the first screw rod 7 can be driven to rotate, so that the first screw rod 7 moves up and down, thereby driving the first piston 4 to move up and down.

[0026] In this embodiment, preferably, as Figure 4 shown, a first cover 11 is threadedly installed on the water outlet 9. By opening the cover, the water sample in the sample storage cylinder 2 can be discharged through the water outlet 9. A water replenishing port 10 is communicated with the top of the sample storage cylinder 2, and a second cover 12 is threadedly installed on the water replenishing port 10. The water replenishing port 10 is arranged in an L shape. When the water sample in the sample storage cylinder 2 is emptied, after closing the water outlet 9, the second cover 12 can be opened, and the circulating water meeting the water quality standard can be injected into the sample storage cylinder 2 through the water replenishing port 10. Then, the water replenishing port 10 is closed, and the first piston 4 is driven to move upward by rotating the first screw rod 7, so that the circulating water in the sample storage cylinder 2 is re-injected into the circulating water outlet 101 through the sampling cylinder 3, thereby supplementing the extracted circulating water. When the first piston 4 moves upward, the second piston 14 is simultaneously driven to move downward by rotating the second screw rod 15 to balance the hydraulic pressure of the circulating water and prevent the hydraulic pressure of the circulating water from being too high.

[0027] In this embodiment, preferably, as Figure 3 shown, there are multiple groups of sampling holes 301. The multiple groups of sampling holes 301 are located at different heights. Each group of sampling holes 301 has two sampling holes, and the two sampling holes 301 are arranged oppositely, so that the water flow can pass through the two sampling holes 301 in sequence to reduce the influence of the sampling cylinder 3 on the circulating water flow.

[0028] The above is only the preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
