Delivery port 4, the body set in deflection tube 2 is in turnover shape；
The big one end of the nozzle diameter of rectifying tube 1 is connected with water inlet deflection tube 7, and water inlet pipe is additionally provided with deflection tube 7 of intaking
6, at least provided with a commutator segment 5 in water inlet pipe 6；
The small one end of the nozzle diameter of rectifying tube 1 is connected with water outlet deflection tube 9.
The fairing of small-bore valve control water meter when in use, first according to water inlet pipe 6, water inlet deflection tube 7, rectifying tube 1, go out
Water deflection tube 9, the order assembly and connection of outlet pipe 8 get up, and when each several part connects, link position will place sealing ring, it is ensured that
The overall tightness of device, to ensure the water inlet 3 of rectifying tube 1 and the direction of delivery port 4 during assembling, to make to connect at water inlet 3
What is connect is the big one end of the nozzle diameter of rectifying tube 1, while ensures correct, the water inlet of the set location and angle adjustment of reflector plate 10
Commutator segment is properly inserted in pipe 6, closes the front end water valve of water pipe system, then the rectification of whole small-bore valve control water meter is filled
Put and be connected in water pipe system, at the same ensure small-bore valve control water meter fairing be set be connected to small-bore valve control water
The front end of table, such current can first pass through the fairing of small-bore valve control water meter, then just flow into small-bore valve control water meter, this
After a little work are all carried out, the front end water valve of water pipe system, integral device can normal work are opened.Current are along water (flow) direction
Direction shown in 15, device each several part is flowed successively through, current can first pass around water inlet pipe 6, and then unstable current can be rectified
Piece 5 is shunted, and can relax after the restructuring of disorderly water stream, and then these current can be flowed into water inlet deflection tube 7, then water
Stream direction is deflected, and the current of deflection obtain buffering once, and these current can enter rectifying tube 1, rectifying tube 1 by water inlet 3
Water inlet 3 is big, and delivery port 4 is small, and when flowing through in rectifying tube 1, the caliber being gradually reduced constrains current, unstable current
Can sufficiently it be buffered, current tend towards stability substantially after rectifying tube 1, then these current outflow delivery port 4, into going out
