The valve body 1 is equipped with sealing ring with 2 joint face of valve seat.
First liquid outlet 8 and third liquid outlet 10 are symmetrical arranged above and below.
Working principle of the utility model is:
The inlet of the liquid delivery outlet different from liquid can be connected to by the utility model, be achieved the purpose that point to conveying.
When the liquid of input only needs to convey at one, handwheel 4 is rotated with 6 slide downward of ovable valve stem, makes the valve being fixedly mounted on valve rod 6
Core I 11 and spool II 12 closes the upper and lower port of valve seat, so that the first liquid outlet 8 and third liquid outlet 10 are closed, together
When, rotating wheel 17, band moving gear I 19 is rotated, and is rotated with it with 19 pitch wheel II 21 of gear I, thus band
Valve ball 16 on turn axis II 20 rotates, and the through-hole gone on valve ball 16 goes out liquid zone 14 for second and is connected to the second liquid outlet 9,
To be delivered to the second liquid outlet 9 for the liquid of input is single；If rotating 4 band of handwheel when input liquid needs to convey at two
6 upward sliding of ovable valve stem, so that the spool I 11 being fixedly mounted on valve rod 6 and spool II 12 opens the upper and lower port on valve seat
It is logical, thus the first liquid outlet 8 starts to be connected to third liquid outlet 10, meanwhile, valve ball 16 is rotated 90 degree by rotating wheel 17, is made
Second goes out liquid zone 14 and the second liquid outlet 9 closure, so that it is separately defeated from the first liquid outlet 8 and third liquid outlet 10 to input liquid
It send, similarly, the liquid of input can also export simultaneously in three liquid outlets.
It by the setting of anti-backflow device, can cause damages to avoid liquid reflux, when the liquid of entrance is flowed into from valve body 1
Out behind liquid zone, by the effect of fluid pressure, the sliding block 24 that spring 25 connects is compressed and is moved forward, thus by sliding slot 23 with
The connectivity part of fixing seat 22 is opened, and input liquid flows into fluid hole 26 from sliding slot 23, to flow to liquid outlet；Work as liquid reflux
When, the tension of spring 25 holds out against sliding block 24 in fixing seat 22, to the connectivity part of sliding slot 23 and fixing seat 22 be closed, gear
The liquid firmly flow backwards.
