As the control core 600 continues to move, the shaft 530 becomes closer to the first rotation dead point.
When the rotating shaft 530 is about to rotate from the second rotation dead point to the first rotation dead point, the stop plate 610 can be attached to the side, away from the control core 600, of the second matching portion 520, and assist in pulling the rotating shaft 530 back to the second rotation dead point, so that the first matching portion 510 completely withdraws from the matching groove 410, the limit of the control ring 500 is released, and meanwhile, the stop plate 610 can also continue to pull the second matching portion 520, so that the control ring 500 moves towards the side, away from the water pipe body 100.
By this design, the reset of the first and second flow restriction rings 200 and 300 can be accomplished by driving the control core 600 alone.
Referring to fig. 9, the present embodiment further provides an intelligent disinfection and administration device 2000 for hospital sewage, which includes: the disinfection tank 2100, the residual chlorine probe 2200, the residual chlorine host 2300, the control center 2400, the chemical tank 2500, the water pump 2600, the metering pump 2700, and the water pressure control mechanism 1000 described above.
The residual chlorine probe 2200 is provided in the sterilizing pond 2100 for detecting chlorine content in wastewater. The residual chlorine probe 2200 is electrically connected with the residual chlorine host 2300, and the residual chlorine host 2300 is electrically connected with the control center 2400, so as to send the chlorine content detection result to the control center 2400.
The water pump 2600, the water pressure regulating mechanism 1000 and the metering pump 2700 are all arranged on the medicament box 2500, and the water inlet 120 of the water pipe body 100 of the water pressure regulating mechanism 1000 is communicated with the water outlet end of the water pump 2600 so as to be used for adding water to the medicament box 2500. Metering pump 2700 is used to dose the liquid medicament in medicament tank 2500 into the sterile basin 2100. Wherein, water pump 2600, water pressure regulation and control mechanism 1000 and measuring pump 2700 all are connected with control center 2400 electricity.
When the liquid medicine in the medicine tank 2500 is used up, solid medicine is put into the medicine tank 2500, and the control center 2400 is used for controlling the water pump 2600 to add water into the medicine tank 2500 and controlling the water pressure regulating mechanism 1000 to control the water pressure change so as to mix the solid medicine.
After solid medicines are put into the medicine box 2500, the control center 2400 is configured to control the water pressure regulating mechanism 1000 to sequentially change the water pressure from a first preset value to a second preset value and a third preset value. The first preset value and the third preset value are smaller than the second preset value, and the third preset value is larger than the first preset value.
Specifically, a liquid level monitoring assembly 2800 for monitoring the height of the liquid level is further disposed in the chemical tank 2500, and the liquid level monitoring assembly 2800 is electrically connected to the control center 2400.
After solid medicine is put into the medicine tank 2500, the control center 2400 controls the water pressure according to the liquid level height in the medicine tank 2500 when controlling the water pressure control mechanism 1000 to control the water pressure.
When the liquid level is lower than the first preset height, controlling the water pressure to be a first preset value. When the liquid level is between the first preset height and the second preset height, the water pressure is controlled to be a second preset value. When the liquid level is higher than the second preset height, controlling the water pressure to be a third preset value.
The first preset height, the second preset height, the first preset value, the second preset value and the third preset value can be flexibly set according to actual needs.
By this design, after the solid medicine is put into the medicine tank 2500, water is added according to the water pressure of the first preset value, that is, the water is added in the state (1) of the water pressure control mechanism 1000. At this time, the water pressure is small, the impact force of the water flow is not large, so that the solid medicament is conveniently flushed, but the solid medicament is not flushed everywhere, the solid medicament is prevented from being adhered to the upper part of the inner wall of the medicament box 2500 and even the top wall, and the medicament loss is avoided.
When the liquid level reaches a first preset height, for example, 100mm, water is added according to a second preset value, namely, water is added in a state (3) of the water pressure regulating mechanism 1000. At this time, the solid medicine is just mixed with water and is not completely dissolved, and at this time, the solid medicine is brewed by using high water pressure, so that the effect of stirring water flow can be achieved, and the complete dissolution of the solid medicine is promoted.
When the liquid level reaches the second preset height, 1000mm, water is added according to a third preset value, namely, water is added in a state (2) of the water pressure regulating mechanism 1000. The solid medicament is completely dissolved, and more water is added in the medicament box 2500 by adopting slightly weaker water pressure, so that liquid splashing in the medicament box 2500 is reduced, and the liquid phase is fully stirred to ensure the uniformity of the medicament.
After the control center 2400 obtains the chlorine content of the wastewater in the disinfection tank 2100 through the residual chlorine probe 2200 and the residual chlorine host 2300, according to a preset dosing rule, the metering pump 2700 is controlled to accurately dose the drug from the drug tank 2500, so as to realize the treatment of the waste chlorine.
In summary, the hydraulic pressure regulating mechanism 1000 provided by the embodiment of the invention is convenient and practical, and can simply and rapidly regulate the hydraulic pressure, thereby greatly improving the execution efficiency and reducing the burden of a user. The intelligent disinfection and dosing equipment 2000 for hospital sewage provided by the embodiment of the invention can effectively reduce the loss of solid medicaments, optimize the mixing effect of the medicaments and further ensure the disinfection effect of the medicaments.
