The utility model has the advantages that：
The utility model hydraulic control one-way valve realizes the break-make of liquid stream by the setting of ball sealer and compensating groove, when liquid stream from
When top connection flows to lower contact, ball sealer is moved in the spherical annular groove of lower contact under the promotion of hydraulic coupling, thus by liquid stream
Channel is closed, and realizes the cut-off of liquid stream；When stream flows to top connection from lower contact, ball sealer is moved under the promotion of hydraulic coupling
In the spherical annular groove of off-load part, enter in compensating groove to make liquid stream pass through the circulation passage between off-load part and lower flowing lumen,
To make liquid stream normal through realizing the circulation of liquid stream.The hydraulic control one-way valve in the application simplifies existing check valve simultaneously
Internal structure makes it rely on hydraulic coupling just to realize the break-make of liquid stream merely, reduces manufacturing cost.
