Control sequence；When the reset, first promotion sequence opening plunger retracts reset to pressure spring, and communication port is made to be connected to unloading port, hydraulic
Driving liquid piggybacking body cavity in element is discharged from unloading port, while flexible valve pin being pushed to retract reset.Above-mentioned novel oilway
Opener being provided separately by sequence opening plunger and flexible valve pin on the way both makes sequence difference occur when resetting, can be real
Now specific operation control, is conducive to build hydraulic automated system, practical.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the preferred embodiment in the utility model.
Fig. 2 to Fig. 5 is the working state schematic representation of the opener of Fig. 1.
Specific embodiment
Referring to Fig.1, the utility model provide the preferred embodiment of novel oilway opener on the way, including valve body 100 with
And it is movably arranged on the flexible valve pin 200 in valve body 100.The valve body 100 can be integrally formed, and may be set to be discrete sets
Part, in the present embodiment, the valve body 100 are preferably made of front valve shell 110 and rear valve body 120, the setting of 110 front end of front valve shell
There is limit base 140, limit base 140 is removable to be arranged on front valve shell 110, and 120 rear portion of rear valve body is provided with valve deck 130.It is described
Valve body 100 is stretched out in the front end of flexible valve pin 200, and flexible 200 front of valve pin is provided with the step matched with limit base 140, institute
It states flexible 200 rear portion of valve pin and is provided with sequence opening plunger 210, offered on sequence opening plunger 210 and lead to flexible valve pin 200
Through-hole.The pressure spring 300 of the reset of promotion sequence opening plunger 210 is provided in the valve body 100.It opens at 100 rear portion of valve body
Oil inlet 131 equipped with connection driving liquid, oil inlet 131 are arranged on valve deck 130, and there are two 100 side wall of the valve body settings
The communication port being connected with Hydraulic Elements, it is preferred that in the present embodiment, the Hydraulic Elements are hydraulic cylinder, the valve body
Side wall is additionally provided with unloading port 111；Wherein the communication port includes the first communication port 121 being arranged close to oil inlet 131 and leans on
The second communication port 112 that nearly unloading port 111 is arranged, the first communication port 121 is connected to oil inlet when sequence opening plunger 210 moves forward
131, the second communication port 112 is connected to unloading port 111 when sequence opening plunger 210 retracts reset.
Referring to Fig. 2, Fig. 3, opener is in running order on the way for novel oilway, and driving liquid enters from oil inlet 131, pushes
Sequence opening plunger 210 and flexible valve pin 200 move forward, and the valve pin 200 that stretches stretches out, and limit base 140 limits stretching for flexible valve pin 200
Distance out, after sequence opening plunger 210 moves forward, oil inlet 131 is connected to the first communication port 121, and driving liquid passes through the first communication port
121 reach hydraulic cylinder.Referring to Fig. 4, Fig. 5, opener is in reset state to novel oilway on the way, loses the suitable of driving liquid driving
Sequence opening plunger 210 retracts reset under the action of pressure spring 300, blocks the first communication port 121, and the connection of unloading port 111 second connects
Port 112,100 inner cavity of driving liquid piggybacking valve body in hydraulic cylinder are discharged by unloading port 111, while pushing flexible valve pin
200 retract reset.
Above-mentioned novel oilway opener being provided separately by sequence opening plunger 210 and flexible valve pin 200 on the way, makes two
Person sequence difference occurs when resetting, it can be achieved that specific operation control, is such as applied when on reinforcing bar bending device, and stretch valve pin
200 may act as central pin shaft, and hydraulic cylinder is bending oil cylinder, when bending resets, due to curved pin and reinforcing bar locking central pin shaft, in
Heart pin shaft is difficult to first retract reset, therefore the oil extraction of hydraulic cylinder elder generation resets, and the valve pin 200 that then stretches is resetted again.This is practical
Opener can be used for building hydraulic automated system to novel oil circuit on the way, practical.
The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means
The technical solution of purpose belongs within the protection scope of the utility model.
