Abstract
Description
Technical Field
[0001] This utility model relates to a combined installation device for a water quality sensor in the semiconductor industry, belonging to the field of sensor installation structure technology. Background Technology
[0002] In the semiconductor industry, standard water quality sensors such as pH meters and conductivity meters provide standard mounting specifications, such as 3 / 4-inch threads, but generally do not have specific matching mounting devices.
[0003] In the existing technology, there is no fixed standard for the installation of water quality sensors during construction and installation. There are generally two installation / testing methods: 1. Direct installation on liquid pipelines; 2. Testing using handheld instruments.
[0004] The two forms mentioned above have the following problems: Form 1, the maintenance and subsequent calibration of the sensor involves cumbersome disassembly; Form 2, handheld instruments cannot achieve continuous detection. Utility Model Content
[0005] This utility model proposes a combined installation device for water quality sensors, which aims to overcome the above-mentioned shortcomings of the existing technology, so as to realize the convenient installation of multiple sensors in one device and simplify installation and maintenance.
[0006] The technical solution of this utility model is a combined installation device for water quality sensors, the structure of which includes a first sampling sleeve, a second sampling sleeve, a third sampling sleeve, a flow indicator, a medium inlet valve, a medium outlet valve, and a drain valve. The first, second, and third sampling sleeves are arranged parallel to each other and spaced apart. The top of the first, second, and third sampling sleeves are respectively welded with internally threaded steel pipes. The internally threaded steel pipes at the top of the first, second, and third sampling sleeves are respectively threaded to a pH sensor, a conductivity sensor, and a dissolved oxygen sensor. The top of one side of the first sampling sleeve is connected to the medium inlet valve through a pipe. The bottom of the other side of the first sampling sleeve is connected to the top of one side of the second sampling sleeve through a pipe with a flow indicator (which has a viewing window). The bottom of the other side of the second sampling sleeve is connected to the top of one side of the third sampling sleeve through a pipe. The bottom of the third sampling sleeve is connected to a tee through a pipe. The other two ports of the tee are respectively connected to the drain valve and the medium outlet valve through pipes. In use, the sampling tube is used to guide the liquid to the medium inlet valve, and the medium outlet valve is connected to the medium return pipe or sewage pipe. Each water quality sensor can be easily installed on the internally threaded steel pipe at the top of each sampling sleeve through its own external thread. The viewing window can be used to observe the medium flow. Each sensor can achieve online continuous detection.
[0007] Preferably, the back sides of the first sampling sleeve, the second sampling sleeve, and the third sampling sleeve are fixed to the mounting panel via connecting rods, thereby achieving modular installation and fixation.
[0008] Preferably, the first, second, and third sampling sleeves are each provided with an internal threaded interface at their bottom. An external threaded plug is threaded to the internal threaded interface at the bottom of the first and second sampling sleeves, and an external threaded ferrule is threaded to the internal threaded interface at the bottom of the third sampling sleeve. The external threaded ferrule is connected to the pipeline. This facilitates the connection and maintenance of each sampling sleeve.
[0009] The advantages of this utility model are: reasonable structural design, which can realize the installation of multiple sensors on a standardized device to achieve simultaneous online detection of pH value, conductivity, dissolved oxygen rate, etc., and the pipeline only needs one source point, which can reduce the number of openings. It is compatible with the standardized threaded installation method of sensors, and is equipped with an observation window and a drainage and sewage discharge structure, which can check the medium flow status in real time, making maintenance convenient and cost-effective.

Install each water quality sensor onto the internally threaded steel pipe 8 at the top of each sampling sleeve via its own external thread; 4. Open the medium inlet valve 3 and the drain valve 6, close the medium outlet valve 7, and guide the medium into the sampling sleeve. Observe whether there is water flow in the viewing window 41. 6. After the water color returns to normal, close the drain valve 6 and open the medium outlet valve 7, and the sensors can then perform continuous online detection.
[0017] As a specific embodiment, all components are made of 304 stainless steel.

The pipe section connecting the bottom side of the sampling sleeve is 45mm long, the pipe section connecting the top side of the sampling sleeve is 48mm long, and the compression elbows... The elbows are 3 / 8-inch equal diameter ferrule elbows; the flow indicator 4 is a DN15 metric internal thread flow indicator, installed on the pipe body between the two ferrule elbows, specifically, the two ends of the flow indicator 4 are connected to the pipe body via DN15 metric external threads converted to 3 / 8-inch ferrules; the medium inlet valve 3, the drain valve 6, and the medium outlet valve 7 are all 3 / 8-inch ferrule straight-through hand valves; the external thread plug 91 is a 3 / 4-inch NPT external thread plug; the external thread ferrule 92 is a 3 / 4-inch NPT external thread converted to a 3 / 8-inch ferrule; the tee 5 is a 3 / 8-inch ferrule equal diameter tee.
