Specific embodiment
As shown in Figure 1, improved hydraulicdirectional control valve, including valve body 1 and set on the driving end 2 at 1 both ends of valve body, valve body 1
Spool 3 is inside set, 3 both ends of spool are equipped with limited block 19, are equipped with oil duct 10, first passage mouth 11, second channel mouth in valve body 1
12, third channel mouth 13,3 both ends of spool are equipped with pillar 14, and 1 both ends of valve body are equipped with the spring cavity 17 being connected to driving end 2, spring
Reset spring 4 is equipped in chamber 17, driving end 2 includes shell 16 and the push rod 5 being set in shell 16, and push rod 5 is close to spool 3 one
End is set in spring cavity 17, and is equipped with limited block 15, and the both ends of reset spring 4 are sheathed on one end of pillar 14 Yu push rod 5 respectively,
5 other end of push rod is fixed by connecting column 8 with the cam 7 for being set to lower section, and cam 7 is connect by shaft 9 with motor 6, driving chamber 2
Outboard end is equipped with hand push rod 18, and hand push rod 18 is flexibly connected with push rod 5.
When left side push rod 5 is by the rotation compression reseting spring 4 of cam 7, and after spool 3 is pushed to the right, oil duct 10
It is connected to first passage mouth 11, second channel mouth 12 is connected to third channel mouth 13；When right side push rod 5 passes through the rotation of cam 7
Compression reseting spring 4 is compressed, and after spool 3 is pushed to the left, oil duct 10 is connected to third channel mouth 13, first passage mouth 11
It is connected to second channel mouth 12.
The utility model is structurally reasonable, easy to use, stable working, and noise is small when use, and equipment attrition is small, service life
It is long.
