Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.
The multi-check valve water supply device shown in fig. 1 comprises a water inlet 5, a first check valve 3 and a water outlet 6 which are connected through pipelines to form a first water supply passage 1; the water inlet 5, the water pump 7, the second check valve 4 and the water outlet 6 are connected in sequence through pipelines to form a second water supply passage 2. The connection direction of the first check valve 3 and the second check valve 4 is from the water inlet 5 to the water outlet 6.
Under the less condition of water pressure of water inlet 5, water pump 7 gets into operating condition, carries out the pressure boost to the rivers that get into water pump 7 from water inlet 5 for the water pressure of delivery port 6 is greater than the water pressure of water inlet 5, and under the effect of first check valve 3, first water supply route 1 ends.
Under the condition that the water pressure of the water inlet 5 is high, the water pump 7 can stop working; the water can be directly supplied through the first water supply path 1; compared with the first water supply passage 1, on the second water supply passage 2, after water flow enters the water inlet end 8 of the water pump from the water inlet 5, the water pressure reaching the water outlet end 9 of the water pump is far lower than the water pressure of the water inlet 5 under the action of internal resistance of the water pump; the water pressure of the water flow entering the second check valve 4 is lower than the water pressure of the water inlet 5, the water pressure entering the first check valve 3 is the water pressure of the water inlet, namely, the water pressure entering the first check valve 3 is greater than the water pressure entering the second check valve 4, so that the water pressure at the water outlet end of the first check valve 3 is greater than the water pressure at the water outlet end of the second check valve 4, the water outlet end of the first check valve 3 and the water outlet 6 are communicated, the actual water pressure at the water outlet end of the second check valve 4 is equal to the water pressure at the water outlet end of the first check valve 3, the second check valve 4 acts, and the second water supply.
