Accommodation groove 364 is offered in side valve seat 361.The accommodation groove 364 has the first side wall 365, described, the first side wall 365
It is arranged far from the side valve mouth 302, offers first through hole 366 on the first side wall 365, the first through hole 366 is used for
The fluid media (medium) for allowing the primary valve 301 to flow to the side valve mouth 302 flows out the main valve housing 31.The main valve housing 31 is equipped with
Second sidewall 313 offers the side valve mouth 302, the second sidewall 313 and first side in the second sidewall 313
Wall 365 is oppositely arranged.Certainly, in other embodiments, the first side wall 365 can also be connected with the second sidewall 366
Or it is perpendicular.Further,
Side of the side valve core 362 far from the side valve mouth 302 is arranged in the side elastic component 363.Specifically, described
One end of side elastic component 363 offsets with the side valve core 362, and the other end and the accommodation groove 364 are far from the side valve mouth 302
The first side wall 365 offset.When the second sidewall 313 is oppositely arranged with the first side wall 365, the side elastic component
363 other end offsets with the second sidewall 313.
When the fluid media (medium) that the primary valve 301 flows into oppresses the side valve core 362, the side elastic component 363 is pressed
Contracting to open the side valve mouth 302, enables fluid media (medium) from institute so that the side valve core 362 leaves the side valve mouth 302
It states primary valve 301 and flows into the side valve mouth 302.When the main valve plug 33 disconnects the primary valve 301 and the side valve mouth 302
Afterwards, the side elastic component 363 is also used to side valve core 362 described in the elastic recovery power drive by its own towards close to the side
The direction of valve port 302 is mobile, to seal the side valve mouth 302.Later, since the fluid media (medium) outside the side valve mouth 302 is to institute
It states side valve core 362 and applies the power towards the side valve mouth 302, the side valve core 362 is tightly pressed on the side valve mouth
On 302, the side valve mouth 302 is sealed, prevent fluid media (medium) is from flowing into the primary valve 301 from the side valve mouth 302.
The course of work of the hydraulically-controlled one-way valve 100 is described below:
When the control element 40 drives the main valve plug 33 towards close to the movement of the direction of the primary valve 301, institute
It states primary valve 301 to be connected with the side valve mouth 302, the fluid media (medium) that the primary valve 301 flows at this time reaches the side valve
At mouth 302, and pressure is applied to the side valve core 362, forces the side elastic component 363 to be compressed, 362 court of side valve core
It is mobile to the direction far from the side valve mouth 302, the side valve mouth 302 is opened, enables fluid media (medium) from the primary valve 301
Flow into 302 mouthfuls of the side valve.After the main valve plug 33 disconnects the primary valve 301 with the side valve mouth 302, the side bullet
Property the side valve core 362 as described in the elastic recovery power drive of its own of part 363 towards close to the side valve mouth 302 direction move
It is dynamic, reseal the side valve mouth 302.Then, described after the control element 40 removes the pressure to the main valve plug 33
Control element 40 is resetted under the action of the restoring force of the main elastic component 34, and the main valve plug 33 is in the auxiliary elastic component
It is resetted under the action of 35 elastic-restoring force, the primary valve 301 and the side valve mouth 302 is disconnected.Later, if having
When fluid media (medium) is want to enter the main valve housing 301 from the side valve mouth 302, the fluid media (medium) applies the side valve core 362
One pressure towards the side valve mouth 302, so that the side valve core 362 is tightly pressed on the side valve mouth 302, thus
Fluid media (medium) cannot flow into the primary valve 301 from the side valve mouth 302.
Compared with prior art, the hydraulically-controlled one-way valve 100 of the utility model, since the side valve door component 36 has back
Function is pressed, not needing in addition one counterbalance valve of increase can be achieved with the one-way flow of fluid media (medium), so as to effectively reduce processing
Process, and reduce production cost.
Those skilled in the art it should be appreciated that more than embodiment be intended merely to illustrate that this is practical new
Type, and be not used as the restriction to the utility model, as long as implementing in the spirit of the utility model to above
Suitably change and change made by mode and all falls in the range of the requires of the utility model protection.
