Background
When the large-flux water purifier is connected with a pipeline machine or other instant heating type heating equipment in parallel, the large-flux water purifier can be started and stopped frequently due to the fact that the water quantity produced by the water purifier is larger than the water quantity of the heating equipment, and the service life of the water purifier is seriously influenced. The traditional way of aiming at the problem is to arrange a transfer water tank in a heating device, water supply is started when the transfer water tank reaches a set low water level, and a water purifier is stopped after the water level reaches a high water level of the transfer water tank. The mode only relatively reduces the starting and stopping frequency of the water purifier, the problem is not really solved, and the problem of secondary pollution caused by the transfer water tank is more and more important.
In response to this problem, a dynamic pressure reducing valve disclosed in 202120079986, when the heating device is in use, controls the pressure below the shut-down pressure of the water purifier through the pressure reducing valve to ensure that the machine can always operate; through setting up the pressure release passageway between water inlet and delivery port, when heating device closed, still there is the water of low discharge from the water inlet to the delivery port, and the water pressure accumulation rises and reaches the disconnection value that sets up the pressure relay that is connected with the water purifier here, then the water purifier shut down. The scheme needs to correspondingly adjust the waterway and the electric control of the matched water purifier, has low universality, and can generate adverse effects on the service life of the water purifier due to the fact that the running pressure in the water purifier is larger than the normal running pressure of the water purifier due to the fact that the water yield is limited forcefully when only the heating device runs.

The one-way valve assembly 11 consists of a one-way valve spring, a conical plug with a sealing ring and a one-way valve seat. The top of the cylindrical structure 104 is smooth. The balance membrane 201 is made of rubber or silica gel. The number of the water passing holes is 1-10, and the hole area is 0.2-100 mm 2; the maximum diameter of the diaphragm seat 202 is smaller than the maximum diameter of the balance diaphragm 201. The area of the balance hole 209 is 0.1-10 mm 2; the length of the overflow hole 306 is greater than 1mm; the wire diameter of the piston return spring 303 is not more than 1mm;
When the heating device interface 501 is used with water, pure water flows in from the pure water inlet 101, after passing through the water passing hole 206 on the balancing diaphragm 201, the piston 301 is pushed to move towards the piston cylinder cover 304, at this time, the piston return spring 303 is compressed, the water required by the heating device flows out from the heating device interface 501 after passing through the piston cylinder 3 and the cylinder cover notch 309, meanwhile, the piston 301 is separated from the top of the conical step 208, a part of pure water flows towards the reflux outlet 102 through the balancing hole 209, when the water quantity of the pure water inlet 101 is greater than the water quantity of the heating device interface 501 plus the water quantity of the balancing hole 209, the pressure of the balancing diaphragm 201 near the pure water inlet 101 is greater than the pressure far away from the pure water inlet 101, at this time, the pure water can push the balancing diaphragm 201 to move towards the piston cylinder 3 due to the effect of the pure water pressure, the balancing diaphragm 201 is separated from the smooth plane at the top of the cylinder structure 104 on the split base 1, when the heating device is closed, the piston 301 moves towards the bottom 302 of the piston cylinder due to the action of the compressed piston return spring 303 until the piston 301 abuts against the smooth plane at the top of the conical step 208, at this time, the pressure of the balancing diaphragm 201 away from the pure water inlet 101 side rises to push the balancing diaphragm 201 towards the cylindrical structure 104 and contacts with the smooth plane at the top of the cylindrical structure 104 to form a sealing surface, so that the backflow outlet 102 is closed, and at this time, the water source outside the backflow outlet 102 cannot enter the inside of the diversion base 1 in a backflow manner due to the action of the one-way valve assembly 11.
When the water is used in a clean faucet, the piston 301 maintains a smooth planar seal with the top of the tapered step 208, and the corresponding balance diaphragm 201 maintains a smooth planar seal with the top of the cylindrical structure 104, so that no water flows out of the return outlet 102.
When the heating device and the clean water tap use water at the same time, since the elastic force of the piston return spring 303 is smaller than that of the check valve 11, water is preferentially supplied to the heating device; since the resistance of the pure water flowing out of the return outlet 102 by pushing up the balance diaphragm 201 and then pushing up the check valve is greater than the resistance of the pure water flowing out of the pure water tap by pushing up only the check valve, the pure water hardly flows out of the return outlet 102 but flows out of the pure water tap preferentially.
In order to further limit the movement of the piston, as an improvement of the technical scheme, at least two piston bone positions 308 are arranged on the piston barrel bottom 302 above the periphery of the piston overflow hole 306, the piston bone positions 308 enclose a piston cavity 305, the piston 301 comprises a piston head 3011 and a piston seat 3012, the head of the piston seat 3012 is provided with a hole, the piston head 3011 is arranged in the hole of the head of the piston seat 3012, at least two piston protrusions 3013 are arranged at the tail of the piston seat 3012, the direction of the piston protrusions 3013 is perpendicular to the axial direction of the piston seat 3012, and each piston protrusion 3013 is respectively positioned in a gap between the piston bone positions 308. The piston head 3011 is made of rubber or silica gel.
In order to achieve sealing, as an improvement of the technical scheme, the outer ring 203 of the balancing diaphragm 201 is in sealing fit with the inner wall of the shunt base 1, and a U-shaped connecting portion 204 is formed inside the outer ring 203 of the balancing diaphragm 201, and the U-shaped connecting portion 204 is clamped on a clamping ring of the shunt base 1.
In order to realize sealing at the connecting position, a first sealing ring 4 is arranged at the position where the upper end of the piston cylinder cover 304 is matched with the diversion upper cover 5; a second seal ring 307 is provided at a portion of the piston cylinder bottom 302 in contact with the piston cylinder cover 304.

The overpressure plug 802 and the pressure-reducing diaphragm 803 are made of rubber or silica gel; the wire diameter of the decompression spring 7 is not less than 1mm.
When the heating device interface 501 is used, the large-flux water purifier is started, generated pure water flows in from the pure water inlet 101, the piston 301 is pushed to move towards the piston cylinder cover 304 after passing through the water passing hole on the balance diaphragm 201, at this time, the piston return spring 303 is compressed, the water required by the heating device flows out from the heating device interface 501 after passing through the piston cylinder 3 and the notch 309, meanwhile, the piston 301 is separated from the top of the conical step 208, a part of pure water flows towards the reflux outlet 102 through the balance hole 209, when the water quantity of the pure water inlet 101 > the water quantity of the heating device interface 501 + the water quantity of the balance hole 209, the pressure of the balance diaphragm 201 on the side close to the pure water inlet 101 is greater than the pressure on the side far away from the pure water inlet 101, at this time, pure water can push the balance diaphragm 201 to move towards the piston cylinder 3 under the action of the pure water pressure, redundant water flows into the reflux outlet 903 through a gap after the balance diaphragm 201 is separated from the smooth plane on the top of the cylindrical structure 104 on the split base 1, and flows into the reflux outlet 102 through a gap 903 after passing through the balance diaphragm 201 and the smooth plane on the top of the cylindrical structure 104, and flows into the reflux inlet 102 through the reflux inlet 102.
At this time, the large-flux water purifier is in a starting state, tap water turns 90 degrees after passing through the external water source inlet 601, the external water source runner 602 and the pressure reducing component base water inlet 8043, enters the pressure reducing component base water outlet 8044 through a gap between the pressure reducing bone parts 8042, and finally is supplied to the large-flux water purifier through the water purifier water inlet interface 902, when the external water source inlet pressure is higher than 0.15MPa in the starting state of the large-flux water purifier, the water pressure at the water purifier water inlet interface 902 pushes the pressure reducing component 804 to move towards the external water source inlet 601 and compress the pressure reducing spring 7, at this time, the end face distance between the pressure reducing plug 802 and the external water source runner 602 is gradually reduced along with the increase of the water pressure, so that the water quantity flowing into the water purifier water inlet interface 902 is not greatly changed even if the pressure at the external water source inlet 601 is large, the pressure at the water purifier water inlet interface 902 is not obviously increased along with the increase of the pressure at the external water source inlet 601, and the water pressure at the water purifier water inlet interface 902 is lower than the shutdown pressure of the large-flux water purifier, and the pure water entering the water inlet 903 can be reused through the water purifier water inlet interface under the condition that the water purifier is not stopped.
When the pressure reducing component 8 moves towards the external water source inlet 601 under the pushing of the water pressure at the water inlet 902 of the water purifier, the volume of a cavity formed by the pressure reducing upper cover 6 and the pressure reducing component 8 is reduced, and redundant air is discharged from the air holes arranged on the surface of the pressure reducing upper cover 6; when the pressure reducing assembly 8 moves towards the water inlet 902 of the water purifier under the pushing of the pressure reducing spring 7, the volume of a cavity formed by the pressure reducing upper cover 6 and the pressure reducing assembly 8 is increased, and air is supplemented through air holes formed in the surface of the pressure reducing upper cover 6.
When the heating device is turned off, the piston 301 moves towards the bottom of the cylinder under the action of the compressed piston return spring 303 until the piston 301 abuts against the smooth plane at the top of the conical step 208, at this time, since the heating device interface 501 and the balance hole 209 can not flow pure water any more, the pressure of the balance diaphragm 201 away from the pure water inlet 101 side can rise, the balance diaphragm 201 is pushed to move towards the cylindrical structure 104 and contact with the smooth plane at the top of the cylindrical structure 104 to form a sealing surface, so that the backflow outlet 102 is closed, and at this time, tap water at the water inlet interface 902 of the water purifier can not flow back into the diversion base 1 due to the action of the one-way valve assembly 11.
When the water is used in a clean faucet, the piston 301 maintains a smooth planar seal with the top of the tapered step 208, and the corresponding balance diaphragm 201 maintains a smooth planar seal with the top of the cylindrical structure 104, so that no water flows out of the return outlet 102.
When the heating device and the clean water tap are used at the same time, the water is preferentially supplied to the heating device because the elastic force of the wire diameter piston return spring 303 is smaller than that of the one-way valve; because the pure water sequentially pushes up the balance diaphragm 201 and the one-way valve and then overcomes the resistance of tap water at the water inlet interface 902 of the water purifier to enter the large-flux water purifier for reuse, the sum of the resistance is larger than the resistance of water which only pushes up the one-way valve to flow out of the pure water faucet, the pure water almost does not enter the large-flux water purifier for reuse through the backflow outlet 102, but flows out of the pure water faucet preferentially.
As a preferred connection and sealing means, the pressure relief assembly upper cover 801 is connected to the pressure relief assembly base 804 by pressure relief threads 8011; a third sealing ring 805 is arranged at the joint of the upper end of the pressure reducing assembly base 804 and the pressure reducing assembly upper cover 801.
As a preferred connection manner between the backflow outlet 102 and the backflow inlet 903, the backflow outlet 102 is a through hole which forms a sealing fit with the check valve assembly 11, 1-2 sealing rings 12 are arranged at the backflow inlet 903 and form a sealing surface in interference fit with the through hole of the backflow outlet 102, and a supporting part 10 for installing the check valve assembly 11 is arranged in the backflow inlet 903.
As a preferred connection mode of the diversion device and the pressure reducing device, a first boss 14 and a first groove 15 are respectively arranged on one side of the backflow outlet 102 of the diversion base 1 and the diversion upper cover 5, and a round hole is arranged in the center of the first groove 15; the pressure reducing base 9 and the pressure reducing upper cover 6 are respectively provided with a second groove 16 and a second boss 17 at one side of the backflow inlet 903, and a round hole is arranged at the center of the second boss 17; the first boss 14 is matched with the second boss 16, the first boss 15 is matched with the second boss 17, a round hole in the first boss 15 and a round hole in the second boss 17 are coaxial, and the tapping screw 13 is screwed in.
