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.

The utility model provides an intelligent water gauge of positive reverse measurement, include: be responsible for 1, be water inlet 10 and delivery port 5 respectively at the person in charge 1 both ends, be responsible for and set gradually first check valve 2 on 1, table body 7 and second check valve 6, it has first through-hole to open on the person in charge 1, the second through-hole, third through-hole and fourth through-hole, first through-hole is located between water inlet 10 and the first check valve 2, the second through-hole is located between first check valve 2 and the table body 7, the third through-hole is located between table body 7 and second check valve 6, the fourth through-hole is located between second check valve 6 and the delivery port 5, be connected with first branch pipe 8 between first through-hole and the third through-hole, be connected with second branch pipe 3 between second through-hole and the fourth through-hole, be provided with third check valve 9 on the first branch pipe 8, be provided with fourth check valve 4 on the second branch pipe 3. The main pipe 1, the first branch pipe 8 and the second branch pipe 3 are all stainless steel pipes, and the meter body 7 can use the existing common flow meter.
