The following describes different states of the water purification system in this embodiment with reference to fig. 1:
in a fully depressurized state:
when the main control valve 11 is opened, the first control valve 21 is closed, the second control valve 31 is opened completely, water enters the main control valve 11 and passes through the pressure reducing structure 32 through the second control valve 31, the pressure reducing structure 32 is bent, the direction of the water entering is changed continuously, so that the pressure and the flow are lost, the purpose of pressure drop is achieved, the raw water after pressure reduction enters the water purifying equipment 40, and the water is produced after the water purifying equipment 40 filters.
When main control valve 11 closed, the intaking stopped, and main control valve 11 is to the pipeline water storage between water purification unit 40 because the multistage of decompression structure 32 is buckled the decompression to eliminate the pressure drop, reach the purpose of solving the water hammer problem, this state can be when intaking the pressure through the reduction pressure of multistage buckling, guarantee that water purification unit 40's the pressure of intaking can not be too big, eliminate the emergence of water hammer phenomenon when main control valve 11 closes simultaneously. However, due to the multi-stage pressure reducing structure 32, both the inflow rate and the pressure of the water are reduced, and the water may be insufficient in the water purifying apparatus 40 when the inflow pressure or the inflow rate is low.
A fully open state:
when the main control valve 11 is opened, the first control valve 21 is opened, the second control valve 31 is closed, the inlet water enters the water purifying device 40 through the main control valve 11 via the first control valve 21, and the water is produced after being filtered by the water purifying device 40. When the main control valve 11 is closed, the water inlet stops, and the pipeline between the main control valve 11 and the water purifying device 40 has no any pressure drop device, so that the water hammer phenomenon can be generated, and the problems of high noise and pipeline vibration are caused. This state can guarantee that water purification unit 40 intakes when intake pressure is lower enough, but there is water purification unit 40 to intake when pressure is higher and too big and close the water hammer phenomenon of taking place when intaking.
Normal use state
The purpose of eliminating water hammer while the pressure drop is adjustable can be achieved by adjusting the opening and closing degree of the first control valve 21 and the second control valve 31, and when the main control valve 11 is opened, a user can adjust the opening and closing degree of the first control valve 21 and the second control valve 31 according to the actual water inlet condition to enable the water inlet flow and the water inlet pressure to reach ideal use conditions. At this opening and closing degree, it is simultaneously ensured that there is no water hammer when the main control valve 11 is closed.
In this state, when the main control valve 11 is opened, a part of the water in the main pipeline passes through the first control valve 21, the other part of the water enters the pressure reducing structure 32 through the second control valve 31 to generate pressure drop, and the two parts of the water are merged again to enter the water purifying device 40 to generate water, so that the sufficient water inflow rate and the appropriate water inflow pressure of the water purifying device 40 can be ensured no matter what conditions the water inflow pressure is under.
When the main control valve 11 is closed, the water inflow stops, and the water stored in the pipeline between the main control valve 11 and the water purifying device 40 is decompressed due to the multi-section bending of the decompression structure 32, so that the pressure drop is eliminated, and the purpose of solving the problem of water hammer is achieved.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
