The bottom outer wall of the reciprocating screw rod 58 is connected to the top outer wall of the first contact pad 59, and the first contact pad 59 is slidably installed inside the first metering barrel 52. The top outer wall of the reciprocating screw rod 58 is connected to the bottom outer wall of the second contact pad 510, and the second contact pad 510 is slidably installed inside the second metering barrel 53. The first metering barrel 52 is located on both sides of the outer wall at the bottom. The walls are respectively connected and installed with a liquid outlet pipe 61 and a liquid inlet pipe 62, and the outsides of the liquid outlet pipe 61 and the liquid inlet pipe 62 are both provided with a one-way valve, and the liquid outlet end of the liquid outlet pipe 61 is located inside the detection barrel 3, and the liquid inlet end of the liquid inlet pipe 62 is located inside the liquid storage tank 63, and the liquid storage tank 63 is connected to the side outer wall of the positioning mounting plate 51, and the side outer wall of the second metering barrel 53 is provided with a supporting back plate 64, and the side outer wall of the supporting back plate 64 is provided with a scale dose scale 65 and a mounting strip 66, and the side outer wall of the mounting strip 66 is provided with a clamping groove at equal intervals, and the clamping groove is connected to the clamping column, and the clamping column is connected to the side outer wall of the auxiliary support plate 67, and the bottom end of the auxiliary support plate 67 A pressure detection sensor 68 is provided on the outer wall, and an indicator arrow 69 is provided on the side outer wall of the second contact pad 510, and the indicator arrow 69 is located directly below the pressure detection sensor 68; when it is necessary to accurately control the extraction dosage of the phosphorus-free water treatment corrosion inhibitor before the detection, it is first necessary to pre-fill the phosphorus-free water treatment corrosion inhibitor into the liquid storage tank 63, and adjust the dosage of the phosphorus-free water treatment corrosion inhibitor required to be extracted according to the detection requirements. When adjusting, it is only necessary to pick up the auxiliary support plate 67 and snap the snap-fit ​​column on its side into the snap-fit ​​groove at the corresponding position indicated by the scale dose ruler 65, and then the auxiliary support plate 67 moves to automatically bring the pressure detection sensor 68 to the specified position;Then the driving motor 55 is controlled to rotate forward. The setting of the auxiliary support frame 54 here plays an auxiliary supporting effect on the driving motor 55. When the driving motor 55 is turned on, it will automatically drive the support shaft to rotate and then drive the driving gear 56 to rotate. Then the rotation of the driving gear 56 will automatically drive the driven gear 57 to rotate and then drive the reciprocating screw 58 to move upward. When the reciprocating screw 58 moves upward, it will automatically drive the first contact pad 59 to move upward. At this time, the one-way valve outside the liquid inlet pipe 62 will automatically open. It is noted here that the one-way valve outside the liquid outlet pipe 61 and the liquid inlet pipe 62 are installed in opposite directions. The output end of the one-way valve outside the liquid outlet pipe 61 faces the first metering barrel 52, and the output end of the one-way valve outside the liquid inlet pipe 62 faces the detection barrel 3. When the one-way valve outside the liquid inlet pipe 62 is opened, the phosphorus-free water treatment corrosion inhibitor inside the liquid storage tank 63 is stored in the first metering barrel 52 through the drainage of the liquid inlet pipe 62. When the reciprocating screw 58 When moving upward, the second contact pad 510 will be synchronously driven to move upward. When the second contact pad 510 moves upward, it will automatically drive the indicator arrow 69 to move upward. When the indicator arrow 69 conflicts with the pressure detection sensor 68 during the movement, the pressure detection sensor 68 transmits information to the pre-set controller, and then the controller automatically controls the drive motor 55 to stop rotating, so as to achieve the effect of stopping extraction, and then restarts the drive motor 55 and controls the drive motor 55 to reverse. At this time, the principle is the same as above, and the reciprocating screw rod 58 automatically moves downward and drives the second contact pad 510 to move downward. When the second contact pad 510 moves downward, the one-way valve outside the liquid outlet pipe 61 will be automatically opened and the phosphorus-free water treatment corrosion inhibitor stored in the first metering barrel 52 will be drained through the liquid outlet pipe 61 and injected into the interior of the detection barrel 3, so that the effect of adding the phosphorus-free water treatment corrosion inhibitor dosage as required is achieved through the above design. ;

[0026] The detection control mechanism 7 includes a protective cover 71, a control component 72 and a power supply component 73. The top outer wall of the support base plate 1 is provided with a protective cover 71, the bottom inner wall of the protective cover 71 is provided with a control component 72 and a power supply component 73, and the interior of the support base 2 is provided with a heating wire, and the heating wire is connected to the power supply component 73; when it is necessary to heat the interior of the detection barrel 3 to simulate a high temperature environment to test the corrosion inhibition effect of the phosphorus-free water treatment corrosion inhibitor, it is necessary to first turn on the control component 72 so that the power supply component 73 heats the heating wire inside the support base plate 1, such as Figure 6 As shown, an electric wire is connected between the support base plate 1 and the power supply 73 to supply power to the heating wire, and then the heating wire heats up and heats up the interior of the detection barrel 3 through heat transfer.

[0027] When the utility model is in use, it is first necessary to add water to the inside of the detection barrel 3 and replenish the phosphorus-free water treatment corrosion inhibitor inside the liquid storage tank 63, and then calculate the dosage of the phosphorus-free water treatment corrosion inhibitor required to be injected according to the dosage of water. When it is necessary to accurately control the extraction dosage of the phosphorus-free water treatment corrosion inhibitor, at this time, it is only necessary to pick up the auxiliary support plate 67 and snap the snap-fit ​​column on its side into the snap-fit ​​groove at the corresponding position indicated by the scale dose scale 65, and then the auxiliary support plate 67 moves to automatically bring the pressure detection sensor 68 to the specified position, and then the extraction work is carried out. At this time, it is necessary to control the drive The driving motor 55 rotates forward. When the driving motor 55 is turned on, it will automatically drive the support shaft to rotate and then drive the driving gear 56 to rotate. Then, the driving gear 56 rotates and automatically drives the driven gear 57 to rotate and then drives the reciprocating screw 58 to move upward. When the reciprocating screw 58 moves upward, it will automatically drive the first resistance pad 59 to move upward. At this time, the one-way valve outside the liquid inlet pipe 62 will automatically open. It is noted here that the installation directions of the one-way valve outside the liquid outlet pipe 61 and the liquid inlet pipe 62 are opposite. The output end of the one-way valve outside the liquid outlet pipe 61 faces the first metering barrel 52, and the output end of the one-way valve outside the liquid inlet pipe 62 faces the first metering barrel 52. The output end of the one-way valve faces the detection barrel 3. When the one-way valve outside the liquid inlet pipe 62 is opened, the phosphorus-free water treatment corrosion inhibitor inside the liquid storage tank 63 is stored in the first metering barrel 52 through the drainage of the liquid inlet pipe 62. When the reciprocating screw rod 58 moves upward, it will also synchronously drive the second resistance pad 510 to move upward. When the second resistance pad 510 moves upward, it will automatically drive the indicating arrow 69 to move upward. When the indicating arrow 69 conflicts with the pressure detection sensor 68 during the movement, the pressure detection sensor 68 transmits the information to the preset controller, and then the controller The controller will automatically control the drive motor 55 to stop rotating, so as to achieve the effect of stopping extraction, and then restart the drive motor 55 and control the drive motor 55 to reverse. At this time, the principle is the same as above. The reciprocating screw 58 automatically moves downward and drives the second contact pad 510 to move downward. When the second contact pad 510 moves downward, the one-way valve outside the liquid outlet pipe 61 will be automatically opened and the phosphorus-free water treatment corrosion inhibitor stored in the first metering barrel 52 will be drained through the liquid outlet pipe 61 and injected into the interior of the detection barrel 3. In this way, the effect of adding the phosphorus-free water treatment corrosion inhibitor dosage as required is achieved through the above design;

[0028] When it is necessary to homogenously mix the phosphorus-free water treatment corrosion inhibitor and water in the detection barrel 3, it is necessary to first turn on the variable speed motor 43. When the variable speed motor 43 is turned on, it will automatically drive the transmission shaft 44 to rotate and then drive the stirring blade 45 to rotate. When the stirring blade 45 rotates, it will automatically mix the raw materials in the detection barrel 3. After the mixing is completed, it is necessary to remove the sealing cover 41 from the upper end of the detection barrel 3 and put the equipment material sample into the detection barrel 3, and then turn on the control component 72 to allow the power supply component 73 to heat the heating wire inside the support bottom plate 1. Figure 6As shown, an electric wire is connected between the supporting base plate 1 and the power supply 73 to supply power to the heating wire. When the heating wire heats up, the inside of the detection barrel 3 is heated by heat transfer, thereby simulating the corrosion inhibition effect of the phosphate-free water treatment corrosion inhibitor in a high temperature environment. After heating for a period of time, the equipment material sample is taken out again and compared with the state before it is put in. If the equipment material sample remains intact, it indicates that the corrosion inhibition effect of the tested phosphate-free water treatment corrosion inhibitor is good. If the equipment material sample is severely corroded, it indicates that the corrosion inhibition effect of the tested phosphate-free water treatment corrosion inhibitor is poor. It is noted here that the variable speed motor 43 and the drive motor 55 can be powered by the existing technology and will not be described in detail here.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
