Description

Technical Field

[0001] This utility model relates to a pH and conductivity probe installation mechanism in a process cooling water system, belonging to the field of process cooling water systems. Background Technology

[0002] In existing process cooling water (PCW) systems, the installation methods for pH probes and conductivity probes mainly include the following:

[0003] 1. Installed in a water tank, in an open-loop process cooling water system, the water in the tank still has a certain flow; however, in a closed-loop process cooling water system, the water in the tank hardly flows. Therefore, this installation method is not conducive to real-time water quality detection.

[0004] 2. Installed on the main supply or return water pipe. Generally, the main supply and return water pipes of the process cooling water system are installed overhead, which is relatively high. This installation method makes the pH probe and conductivity probe installed at a high height, which is not convenient for subsequent probe calibration, maintenance and other operations. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pH and conductivity probe installation mechanism in a process cooling water system to solve the problems mentioned in the background technology. This utility model facilitates the installation, calibration, maintenance and replacement of pH and conductivity probes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pH and conductivity probe installation mechanism for a process cooling water system, comprising a water supply main pipe and a return water main pipe. A detachable first ball valve is installed on the outer surface of both the water supply main pipe and the return water main pipe. A downwardly arranged water inlet pipe is installed at the end of the first ball valve on the water supply main pipe away from the water supply main pipe and at the end of the first ball valve on the return water main pipe away from the return water main pipe. A second ball valve is installed at the end of each of the two water inlet pipes away from the first ball valve. Two transparent test cups are connected by a pipe between the two second ball valves. The two test cups are connected to the two second ball valves respectively via a union joint. A pH probe and a conductivity probe are respectively installed inside the two test cups. A collection device for collecting leaked water is located directly below each test cup.

[0007] Furthermore, the collection device includes a water storage box, which is located directly below the test cup. The first ball valve, the second ball valve, and the union joint are all located directly above the water storage box. Two hanging rods are installed at the bottom of the water storage box, and the two hanging rods are connected to the main water supply pipe and the main water return pipe respectively through connectors. A drain valve is installed at the bottom of the water storage box.

[0008] Furthermore, the connector includes an upper semi-circular ring, and both the return water main pipe and the supply water main pipe are fitted with an upper semi-circular ring and a lower semi-circular ring. Both ends of the upper semi-circular ring are connected and fixed with upper connecting ears, and both ends of the lower semi-circular ring are connected and fixed with lower connecting ears. The upper connecting ears are connected to the lower connecting ears by a fastener formed by a first screw and a nut. The upper end of the hanger rod is connected to the lower semi-circular ring by a second screw.

[0009] Furthermore, a connecting plate is fixedly connected to the upper end of the boom, and a protrusion is fixedly connected to the lower part of the outer surface of the lower semicircular ring. The second screw passes through the small hole on the connecting plate and is threaded into the screw hole on the protrusion.

[0010] Furthermore, the bottom of the water storage box is equipped with multiple evenly arranged straight threaded cylinders, which are arranged vertically and have internal threads that connect to support screws.

[0011] Furthermore, a base is installed at the lower end of the support screw, and the diameter of the base is larger than the outer diameter of the straight threaded cylinder.

[0012] The beneficial effects of this utility model are:

[0013] 1. By utilizing the pressure difference between the water supply main pipe and the return main pipe, a water flow direction can be formed from the water supply main pipe to the return main pipe. The water in the test cup is circulating in real time, which can detect changes in water quality in real time. The test is accurate and has no lag. The test cup is transparent, which also makes it easy for people to observe the water quality.

[0014] 2. With the help of the water pipe, the pH probe and conductivity probe are installed in the test cup close to the ground, which facilitates the later operation of probe calibration, maintenance and replacement. When performing the above operations, just close the second ball valve before and after the test cup. At the same time, the test cup is equipped with a union joint before and after, so that it is easy to remove and replace if the test cup is damaged or leaks.

[0015] 3. When the test cup, the first ball valve, or the second ball valve leaks due to sealing failure, the leaked water drips into the water storage box, thus collecting the leaked water and preventing it from dripping into the working environment.

[0016] 4. After the second screw passes through the connecting plate and the threaded connection of the protrusion, the connection between the hanger and the lower semi-circular ring is completed. Using the structure formed by the upper and lower semi-circular rings, the two hangers are installed on the water supply main pipe and the return main pipe respectively, thus restricting the position of the water storage box. Adjust the length of the support screw in the straight threaded cylinder so that the chassis contacts the ground. At this time, the support screw, chassis and straight threaded cylinder work together to support the water storage box and improve the stability of the structure. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1 and Figure 2This utility model provides a technical solution: a pH and conductivity probe installation mechanism in a process cooling water system, including a water supply main pipe 1 and a return water main pipe 5. A detachable first ball valve 3 is installed on the outer surface of both the water supply main pipe 1 and the return water main pipe 5. A downwardly arranged water inlet pipe 4 is installed at the end of the first ball valve 3 on the water supply main pipe 1 away from the water supply main pipe 1 and at the end of the first ball valve 3 on the return water main pipe 5 away from the return water main pipe 5. A second ball valve 16 is installed at the end of each of the two water inlet pipes 4 away from the first ball valve 3. Two transparent test cups 20 are connected by a pipe between the two second ball valves 16. The two test cups 20 are connected to the two second ball valves 16 respectively via a union joint 17. A pH probe 18 and a conductivity probe 18 are respectively installed inside the two test cups 20. The head 19 utilizes the pressure difference between the water supply main 1 and the return main 5 to form a water flow direction from the water supply main 1 to the return main 5. The water in the test cup 20 is circulating in real time, which can detect changes in water quality in real time. The test is accurate and has no lag. The test cup 20 is transparent, which also makes it easy for people to observe the water quality. Under the action of the water inlet pipe 4, the pH probe 18 and the conductivity probe 19 are installed in the test cup 20, which is close to the ground, to facilitate the later operation of probe calibration, maintenance and replacement. When performing the above operations, it is only necessary to close the second ball valve 16 before and after the test cup 20. At the same time, the test cup 20 is equipped with a union joint 17 before and after it. If the test cup 20 is damaged or leaks, it is easy to remove and replace it.

[0024] See Figure 1 and Figure 2 A water storage box 11 is located directly below the test cup 20. The first ball valve 3, the second ball valve 16, and the union connector 17 are all located directly above the water storage box 11. Two hanging rods 9 are installed at the bottom inside the water storage box 11. An upper semi-circular ring 2 and a lower semi-circular ring 6 are fitted on both the return water main pipe 5 and the supply water main pipe 1. Both ends of the upper semi-circular ring 2 are connected and fixed with upper connecting ears 22, and both ends of the lower semi-circular ring 6 are connected and fixed with lower connecting ears 23. The upper connecting ears 22 are fastened to the lower connecting ears by a fastener formed by the first screw 21 and the nut 24. The lugs 23 are connected, and the upper end of the rod 9 is connected and fixed with a connecting plate 10. The lower part of the outer surface of the lower semicircular ring 6 is connected and fixed with a protrusion 7. The second screw 8 passes through the small hole on the connecting plate 10 and is threaded into the screw hole on the protrusion 7. A drain valve 12 is installed at the bottom of the water storage box 11. When the test cup 20, the first ball valve 3, and the second ball valve 16 leak water due to sealing failure, the leaked water drips into the water storage box 11, realizing the centralized collection of leaked water and preventing water from dripping randomly into the working environment.

[0025] See Figure 1 and Figure 3Multiple evenly arranged straight threaded cylinders 13 are installed at the bottom of the water storage box 11. The straight threaded cylinders 13 are arranged vertically, and the internal threads of the straight threaded cylinders 13 are connected to the support screws 15. The lower end of the support screws 15 is equipped with a base plate 14. The diameter of the base plate 14 is larger than the outer diameter of the straight threaded cylinders 13. After the second screw 8 passes through the connecting plate 10 and the protrusion 7 and is threadedly connected, the connection between the hanger 9 and the lower semi-circular ring 6 is completed. The structure formed by the upper semi-circular ring 2 and the lower semi-circular ring 6 is used to install the two hangers 9 on the water supply main pipe 1 and the return water main pipe 5 respectively, thereby restricting the position of the water storage box 11. The length of the support screw 15 inside the straight threaded cylinder 13 is adjusted so that the base plate 14 contacts the ground. At this time, the support screw 15, the base plate 14 and the straight threaded cylinder 13 work together to support the water storage box 11 and improve the stability of the structure.
