The working principle is as follows: the anti-backflow device is installed, and a water path of the anti-backflow device is connected to a main water path close to a water tank for secondary water supply through a water inlet pipe 102 and a water outlet pipe 103 in the main cavity assembly 1;
when the water supply system is used normally, the pressure pump connected with the water tank for secondary water supply is started, and the secondary water supply at the tail end can be used;
after the water in the water tank is pressurized for the second time by the pressurizing pump, the water enters the anti-backflow device through the water inlet pipe 102, due to the pressure of the secondary water supply, a water source with certain pressure can enter the anti-backflow cavity 202 through the neutral position between the water inlet pipe 102 and the main support frame 204, since the plunger seat 205 is slidably connected in the inner cavity of the anti-backflow cavity 202 after being sealed by the sealing ring 215, and a top spring 213 is connected between the rear end of the bullet socket 205 and the bottom cavity of the anti-backflow cavity 202, when the pressure of the water source is greater than the pressure of the top spring 213, the external water source pushes the plunger holder 205 to move toward the bottom cavity of the anti-backflow cavity 202, and a front limit plate 209 coupled to the rear end of the plug seat 205 is overlapped on the rear end of the water passing hole 203, therefore, an external water source can be communicated with the space formed by the outer wall of the main fixed seat 201 and the inner cavity of the main cavity 101 through the inner cavity of the anti-backflow cavity 202 and the plurality of groups of water through holes 203;
at this time, because the plunger seat 205 in the main anti-reflux assembly 2 is in an open state, and the linkage sealing plate 303 in the linkage anti-reflux assembly 3 is in magnetic transmission connection with the plunger seat 205, when the plunger seat 205 is opened, the plunger seat 205 can drive the outer magnetic ring 402 to move towards the water outlet end of the main cavity 101 through the magnetic force of the inner magnetic ring 401, so as to drive the main rack 404 to move, the main rack 404 drives the joint gear 408 to rotate coaxially through matching with the main gear 405, so that the joint gear 408 drives the joint rack 409 to move upwards, so as to drive the outer magnetic strip 413 to move upwards through the joint rack seat 410, the outer magnetic strip 413 drives the linkage sealing plate 303 to move upwards through the magnetic force of the inner magnetic strip 412, so that the linkage sealing plate 303 is also in an open state;
the water source entering the inner cavity of the main cavity 101 enters the latch post 305 through the spring-actuated water inlet tube 311 in the linkage anti-backflow assembly 3, the water source pushes the spring-actuated rear seat 309 to move towards the direction of the linkage sealing plate 303, the spring-actuated rear seat 309 elastically drives the latch 306 to move towards the direction of the linkage sealing plate 303 through the spring-actuated spring 308, after the pressure of the water source is dynamically balanced with the elastic force of the spring-actuated spring 308, the latch 306 can be elastically clamped in the latch clamping hole 307, the linkage sealing plate 303 is locked at the opened position, and the passing performance of the water source at the water outlet end of the main cavity 101 cannot be influenced;
at this time, after entering the main cavity 101, an external water source can supply water to a user at the tail end through the water outlet pipe 103;
at the moment that a pressure pump of the secondary water supply tank stops, certain negative pressure can be generated on water supply connected with the secondary water supply tank, so that water in a water supply pipeline can flow back into the water supply tank, if a water source at the tail end does not generate impurities such as bacteria for a long time, water flowing back to the tail end of the water supply tank can pollute the water supply tank, and the water safety of a tail end user is finally influenced;
after the secondary water supply tank booster pump stops, due to the reduction of the water source pressure and the generation of instant negative pressure, the elasticity of a top spring 213 in the main anti-reverse flow assembly 2 is larger than the pressure of the water source, so that the elastic plug seat 205 moves towards the direction of the water inlet end of the main cavity 101 and finally moves to the front end of the inner cavity of the anti-reverse flow cavity 202, the water supply source is isolated from the water path communication of the water through hole 203, and the water inlet end of the main cavity 101 is sealed;
meanwhile, when no water source pressure exists at the rear end of the springing rear seat 309, the springing buckle 306 is driven to move in the direction away from the springing buckle clamping hole 307, and finally the springing buckle is separated from being matched with the springing buckle clamping hole 307;
when the plunger seat 205 moves towards the water inlet end of the main cavity 101, the plunger seat 205 can drive the outer magnetic ring 402 to move towards the water inlet end of the main cavity 101 through the magnetic force of the inner magnetic ring 401, so as to drive the main rack 404 to move, the main rack 404 drives the joint gear 408 to rotate through the matching with the main gear 405 coaxially, so that the joint gear 408 drives the joint rack 409 to move downwards, so that the joint rack seat 410 can drive the outer magnetic strip 413 to move downwards, the outer magnetic strip 413 drives the linkage sealing plate 303 to move downwards through the linkage with the magnetic force of the inner magnetic strip 412, so that the linkage sealing plate 303 can move downwards to the front of the water outlet end of the main cavity 101, and the sealing of the water outlet end of the main cavity 101 is realized through the sealing matching of the linkage sealing plate 303 and the linkage sealing plate sealing strip 302;
through the mode that the water source drives the main anti-backflow assembly 2 and the linkage anti-backflow assembly 3 to link, the dual anti-backflow effect of a secondary water supply pipeline can be achieved without external driving, and the water source anti-backflow system is simple in structure, energy-saving and environment-friendly.
Preferably, the front end of the elastic rod 206 is further fixedly connected with a rear limiting plate 208, and the rear limiting plate 208 is located outside the main support frame 204 and used for limiting the elastic rod 206, so that the elastic rod 206 is not separated from the main support frame 204, and therefore, the function of the main anti-reverse flow assembly 2 can be stably realized.
Preferably, the plurality of magnetic coupling seats 210 form a ring-shaped structure centered on the axial center of the anti-backflow cavity 202 for mounting the inner magnetic ring 401.
Preferably, a position in the inner cavity of the latch post 305, which is close to the latch water outlet pipe 312, is fixed with a latch rear limit 310 for limiting the sliding position of the latch rear seat 309, so that the latch rear seat 309 cannot be separated from the inner cavity of the latch post 305, and the limiting function of the latch 306 can be realized.
Preferably, a check valve 314 is further fixedly mounted at a position where the bouncing water outlet pipe 312 is connected with the inner cavity of the main cavity 101, and the check valve 314 enables water in the inner cavity of the main cavity 101 to enter the snapping column 305 only through the bouncing water inlet pipe 311 and to flow back to the inner cavity of the main cavity 101 through the bouncing water outlet pipe 312.
