Specific embodiment
Below in conjunction with attached drawing, specific embodiments of the present invention will be described in further detail.
It is provided, a kind of flow control valve of the high-performance without water hammer, including valve body 1, is equipped in valve body 1 into logical by Fig. 1 to Fig. 3
Road 2 and out channel 3 are sealed and installed with valve deck 4 on valve body 1, which is characterized in that be equipped between the stand in channel 2 and out channel 3
It is embedded in valve body 1 and by stand in channel 2 and the horizontal valve seat 5 of the blocking in channel 3 out, sealing rotation connection is erected on the valve deck 4
To valve shaft 6, the lower end of valve shaft 6 is cased with the spool 7 of plate-like, and spool 7 is connect with 5 rotary seal of valve seat, and valve seat 5 is equipped with first
Arc groove 8, spool 7, which is equipped with, to be equipped with the second arc groove 9 of 8 face of the first arc groove, valve rod positioned at 7 top of spool
Protrusion 10, is equipped with the pressure spring 11 for making spool 7 compress valve seat 5 covered on valve shaft 6 between protrusion 10 and spool 7, valve shaft 6 is stretched upwards
Valve deck 4 and extension end are equipped with driven wheel of differential 12 out, and cylinder body 13, the lower end of valve body 1 and stand in channel are fixed on the valve body 1
2 are connected, and piston 14 is equipped in cylinder body 13, and the upper end of piston 14 is fixed with piston rod 15, and the upper end fixation of piston rod 15 is with teeth
Item 16 is equipped with transmission shaft 17 by bearing block on cylinder body 13, is equipped on transmission shaft 17 and 16 meshed gears 18 of rack gear, transmission
The drive bevel gear 19 engaged with driven wheel of differential 12 is installed, the fluid pressure in stand in channel 2 is bigger, the first arc on axis 17
The area of 9 face of slot 8 and the second arc groove is smaller.The effect of pressure spring 11 increases the active force between spool 7 and valve seat 5, improves
Sealing performance between spool 7 and valve seat 5.
The cylinder body 13 is connected by water inlet pipe 20 with stand in channel 2, and water inlet pipe 20 extend into the middle part of stand in channel 2.
