And it is the extending direction "-" type notch consistent with piston trajectory direction to be depressured mouth；Delivery outlet is located at partition board far from drop
Press the side of mouth；
The one end of partition board far from driving motor is equipped with the runner of connection piston channel and delivery outlet；Equipped at outlet port is equipped with flow velocity
Sensor；Flow sensor and driving motor are all connected with the control unit of the control valve, and control unit is used for according to flow-velocity sensing
The detected value control driving motor work of device.
Preferably：Piston uses rubber bodies.
Preferably：Delivery outlet is located at the one end of partition board far from runner.
Preferably：Flow sensor is located at delivery outlet close to the side of runner and is arranged far from runner.
Preferably：Partition board is arc panel.
A kind of flow velocity adjustment type control valve that the disclosure proposes, it is real to the rate of outflow of equipped at outlet port by flow sensor
When monitor, when flow velocity is too fast, opens decompression mouth at this point, controlling piston movement by driving motor and adjust decompression mouth aperture, just
The hydraulic pressure in output cavity can be alleviated, to by the cooperation for being depressured mouth and delivery outlet, ensure the balance of the control valve input and output,
And delivery outlet is divided by being depressured mouth, to ensure the gentle output of the control valve.Conversely, when close by mobile piston
Piston channel is sealed, decompression mouth is isolated with output cavity, then can avoid decompression mouth and delivery outlet is divided, ensure the output stream of delivery outlet
Speed.
When a kind of flow velocity adjustment type control valve work that the disclosure proposes, input liquid enters output cavity by spool, so
It is exported afterwards by being depressured mouth and delivery outlet.Delivery outlet is output to designated position for that will export intracavity liquid, and decompression mouth is for delaying
The operating pressure of delivery outlet is solved, the hydraulic pressure in output cavity is reduced, mouth aperture is depressured to the defeated of delivery outlet by adjusting to realize
Go out flow velocity to be adjusted.
Description of the drawings
Fig. 1 is a kind of flow velocity adjustment type control valve partial sectional view that the disclosure proposes；
Fig. 2 is the vertical view of Fig. 1.
Specific implementation mode
Referring to Fig.1, a kind of flow velocity adjustment type control valve that the disclosure proposes, valve body 1 are defeated equipped with being connected to output cavity 2
Outlet 3 and decompression mouth 4.Partition board 5 is equipped in output cavity 2, partition board 5 coordinates 2 inner wall of output cavity to form piston channel 6.Piston channel 6
Piston 7 is inside installed, piston 7 is connected with driving motor 9 by piston rod 8, drives piston 7 in work will pass through driving motor 9
Plug moves back and forth in channel 6.Piston channel 6 is sealed close to one end of driving motor 9.Decompression mouth 4 is connected to piston channel 6, and
It is the extending direction "-" type notch consistent with 7 movement locus direction of piston to be depressured mouth 4, in this way, moved by piston 7,
The effective length of adjustable decompression mouth 4, that is, adjust the aperture of decompression mouth 4.Delivery outlet 3 is located at one of partition board 5 far from decompression mouth 4
Side.In present embodiment, when control valve works, input liquid enters output cavity 2 by spool, then by being depressured mouth 4 and defeated
3 output of outlet.Specifically, in present embodiment, delivery outlet 3 is used to liquid in output cavity 2 being output to designated position, is depressured mouth
4 operating pressure for alleviating delivery outlet 3, reduces the hydraulic pressure in output cavity 2, and 4 aperture pair of mouth is depressured by adjusting to realize
The output flow velocity of delivery outlet 3 is adjusted.
The one end of partition board 5 far from driving motor 9 is equipped with the runner of connection piston channel 6 and delivery outlet 3, to ensure that piston is logical
The hydraulic pressure that hydraulic pressure in road 6 goes out at delivery outlet 3 is consistent, to ensure to be depressured the response of 4 aperture of mouth and flow velocity adjusting at delivery outlet 3
Efficiency.Flow sensor 10 is equipped at delivery outlet 3.Flow sensor 10 and driving motor 9 are all connected with the control list of the control valve
Member, control unit are used to control driving motor 9 according to the detected value of flow sensor 10 and work.
In present embodiment, the rate of outflow at delivery outlet 3 is monitored in real time by flow sensor 10, when flow velocity mistake
Soon, illustrate that the hydraulic pressure in output cavity 2 is larger, the input speed of the control valve is too fast, at this point, controlling piston 7 by driving motor 9
Mobile decompression mouth 4 of opening simultaneously adjusts decompression 4 aperture of mouth, can alleviate the hydraulic pressure in output cavity 2, to by being depressured mouth 4 and defeated
The cooperation of outlet 3 ensures the balance of the control valve input and output, and is divided by being depressured 4 pairs of delivery outlets 3 of mouth, to protect
Demonstrate,prove the gentle output of the control valve.Conversely, when by mobile 7 sealing piston channel 6 of piston, will decompression mouth 4 and output cavity 2 every
From, then it can avoid decompression 4 pairs of delivery outlets 3 of mouth and divide, the output flow velocity of guarantee delivery outlet 3.
In present embodiment, piston 7 uses rubber bodies, to ensure effective sealing to piston channel 6.Present embodiment
In, partition board 5 is arc panel, to coordinate 2 inner wall of output cavity to form the piston channel 6 of inner wall smooth, to ensure what piston 7 moved
Steadily.
In present embodiment, delivery outlet 3 is located at the one end of partition board 5 far from runner 11, to ensure that the flow at delivery outlet 3 is even
Speed avoids being influenced by decompression 4 shunting of mouth.Specifically, in present embodiment, it is close that flow sensor 10 is located at delivery outlet 3
The side of runner 11, flow velocity cannot accurately be detected by being mounted on dead angle position in output cavity 2 to avoid flow sensor 10；And it flows
Fast sensor 10 is arranged far as possible from runner 11, is interfered to the detection of flow sensor 10 to avoid runner shunting.
The above, only this disclosure relates to preferable specific implementation mode, but the protection domain of the disclosure not office
