Drip-proof idle rotation-proof water meter connecting component

An anti-dripping, anti-water leakage, anti-idle water meter is provided mainly to solve the problems that flow of pickup of present water meter is great, dripping and leakage and idle of the water meter, characterized in that: a trap valve (2), a magnetic ring (3) with sieve pore and a circular armor plate (4) with sieve pore are orderly fixed from right to left in a connection pipe (1). The circular armor plate (4) is provided with a water inlet passage (5) in upper part; a sliding magnetic ring (6) in built in the left sliding road of the circular armor plate (4) in the connection pipe (1). The sliding magnetic ring (6) is provided with a water outlet passage (7) in lower part. The anti-dripping, anti-water leakage, anti-idle water meter is anti-dripping, anti-water leakage, convenient to mount, low in cost, anti-idle for the water meter.
