The working principle of the multistage constant-current faucet based on the high sealing performance is as follows:
Firstly, when the device is used, the device is firstly placed in a working area, an external filter is arranged at the pipe orifice of a water inlet pipe 5, then the filter is connected with an external water pipe, and the rotation is required to be carried out by rotating the top side rotary table of a double-layer rotary knob 21 during the installation, so that the rotary table at the top of the double-layer rotary knob 21 and a connecting rod 22 at the bottom of the double-layer rotary knob 21 drive a pressure guide piece 26 to rotate and adjust to a slow-open state;
Secondly, in the use process, a user rotates the turntable at the bottom side of the double-layer knob 21 to drive the clamping tube 23 and the rotating piece 24 to rotate, and at the moment, the rotating piece 24 rotates to perform up-and-down displacement action due to the fact that the rotating groove at the outer surface of the rotating piece is in transmission with the internal threads of the valve body 1, so that the rotating piece 24 drives the piston rod 281 and the sealing disc 284 to rotate in a following way, at the moment, the piston rod 281 is driven to move upwards to stop blocking the notch at the bottom of the first sealing barrel 287, and water flows into the first sealing barrel 287 and flows out into the valve body 1 through the flow-fixing holes 285;
thirdly, at this time, a certain flow rate of water can be limited to pass through due to the aperture factor of the constant flow hole 285, after the internal pressure of the first sealing cylinder 287 is gradually increased, the sealing disc 284 and the piston rod 281 are subjected to upward extrusion force, so that the piston rod 281 extrudes the gas in the bottom groove of the sealing groove 25, and at this time, the gas flow in the sealing groove 25 flows to the guide pressing piece 26 through the flow passage 27 on the side surface thereof;
Fourth, because the pressure guide piece 26 is in a slow opening state, that is, the conical opening of the conical cover 263 faces the lower cavity of the bottom groove of the sealing groove 25, the air flow in the sealing groove 25 enters the rotating disc 261 and the conical cover 263 through the flow channel 27 and flows out to the lower half cavity of the bottom groove of the sealing groove 25 through the notch of the conical cover 263, the conical cover 263 is arranged to be conical, and the flow blocking plate 264 is arranged to partially block the air flow flowing through, so that obvious air pressure difference is formed at the notches on two sides of the rotating disc 261, the piston rod 281 drives the sealing disc 284 to counterbalance the first sealing cylinder 287 by air pressure, the sealing disc 284 is prevented from moving upwards out of the first sealing cylinder 287 due to the water pressure when not being regulated, the constant flow failure phenomenon is avoided, and the first-stage constant flow is realized;
Fifth, the user can rotate the knob 36, so that the knob 36 drives the gear set 35 to drive and drives the slotted rotary table 33 to rotate through the connecting bridge 34, when the slotted rotary table 33 rotates, the notch on the slotted rotary table 33 is overlapped with the notch of the slotted fixed plate 32 to enable water flow in the valve body 1 to flow out, and the slotted fixed plate 32 and the notch with different sizes on the slotted rotary table 33 are overlapped by rotation to change the size of the flow passage, so that secondary constant flow is realized;
Sixthly, a user can continuously rotate the bottom turntable of the double-layer knob 21 in the same direction according to the use condition, so that the rotating piece 24 drives the piston rod 281 and the sealing disk 284 to move upwards out of the first sealing cylinder 287, water in the water inlet pipe 5 can enter the valve body 1 at full speed, the water pressure in the valve body 1 is enhanced, and the multistage constant flow effect in the valve body 1 is realized;
seventh, after the use, the user rotates the bottom turntable of the double-layer knob 21 in the opposite direction, so that the double-layer knob 21 and the rotating member 24 drive the piston rod 281 and the sealing disk 284 to displace downwards and enter the first sealing cylinder 287, and at this time, the return spring 282 pressed by the piston rod 281 provides elastic force to assist the rapid downward movement of the piston rod 281;
Eighth, when the piston rod 281 moves down, the air flow in the upper cavity of the sealing groove 25 flows into the pressure guiding piece 26 rapidly, and the air flow flows back to the lower cavity of the sealing groove 25 through the flow channel 27 rapidly due to the conical shape of the conical cover 263, the flow blocking plate 264 and the reset filling block 265 on the side surface of the flow blocking plate 264, so as to realize the rapid downward movement of the piston rod 281, realize the rapid closing of the first control 2, and avoid the phenomena such as dripping.
The invention provides a multistage constant flow tap with high sealing performance through improvement, a first control part 2 is arranged in a valve body 1, a double-layer knob 21 is rotated to drive a sealing element 28 to move up and down through a clamping pipe 23 and other parts so as to realize graded constant flow adjustment through a constant flow hole 285 and a first sealing cylinder 287, and a pressure guide part 26 is used for partially blocking the flowing air flow, so that the sealing disc 284 is prevented from moving out of the first sealing cylinder 287 upwards due to water pressure when not being adjusted, and the phenomenon of constant flow failure is avoided; the air flow is enabled to flow back to the lower cavity of the sealing groove 25 through the flow channel 27 rapidly through the conical shape of the conical cover 263, the flow blocking plate 264 and the reset filling block 265 on the side surface of the flow blocking plate 264, so that the piston rod 281 is moved down rapidly, the first control 2 is closed rapidly, and the phenomena of dripping and the like are avoided; through setting up second regulating piece 3 in valve body 1, drive fluting carousel 33 and fluting fixed plate 32 through gear train 35 and connecting bridge 34 through rotating knob 36 and go up the notch overlap of different sizes in order to change the runner size, and then realize second grade constant current.
