Water in pressure chamber can flow to extraneous ring by the gap of valve element 253 and the surface irregularity of the touching position of pressure relief valve body 251
In border, the slow pressure release of hydraulic cavities is realized.
Specifically, the surface irregularity that valve element 253 is in contact with pressure relief valve body 251；And/or, pressure relief valve body 251 and valve
The surface irregularity that core 253 is in contact；When valve element 253 is in contact with pressure relief valve body 251, hydraulic cavities can connect with external environment
It is logical., can also be uneven in pressure relief valve body 251 that is, can be with uneven on valve element 253, can with valve element 253 with
It is uneven in pressure relief valve body 251.It is uneven to be formed by curved surface, it can also be formed by protuberance.So, valve element
253 with pressure relief valve body 251 when being in contact, and rough surface can play a part of current limliting, make the slow pressure release of hydraulic cavities.
When brewing cavity is with hydraulic cavities pressure release, brewing cavity quick pressure releasing, the slow pressure release of hydraulic cavities, until after the completion of brewing cavity pressure release or fast
Want after the completion of pressure release, hydraulic cavities start quick pressure releasing.
Certainly, valve element 253 can also can realize the structure of pressure release with the touching position of pressure relief valve body 251 for other.
Further, during the control of unloading pressure control valve 240 hydraulic cavities pressure release, the hydraulic pressure in hydraulic cavities is more than or equal to pressure release bullet
The elastic force of spring 252, the compression pressure release of valve element 253 spring 252, and valve element 253 is in contact with pressure relief valve body 251, pass through capillary
Groove 2531 is to hydraulic cavities pressure release.Hydraulic pressure in hydraulic cavities is less than the elastic force of pressure release spring 252, and pressure release spring 252 is with movable valve plug
253 reset, and there is distance between valve element 253 and pressure relief valve body 251, hydraulic cavities are by distance to hydraulic cavities pressure release.
Valve element 253 is withstood by the pressure release spring 252 being pressurized to be assemblied in the inner chamber of pressure relief valve body 251.During pressure release, valve element
253 overcome the elastic force of pressure release spring 252 in hydraulic cavities in the presence of the water of elevated pressures so that the same relief valve of valve element 253
Body 251 is in contact, so that the plane relative with pressure relief valve body 251 of valve element 253 or curved surface are compressed.The purpose of capillary channel 2531 exists
In realizing not being fully sealed for two laminating planes or curved surface.It still is able to make current when i.e. valve element 253 is in contact with pressure relief valve body 251
Cross.Slow pressure release is started by capillary channel 2531 in this case.Set when the hydraulic pressure in hydraulic cavities drops to pressure release spring 252
Elastic force when, valve element 253 departs from pressure relief valve body 251 in the presence of pressure release spring 252, and thus the water of hydraulic cavities start quickly to let out
Pressure, now piston head 213 starts Rapid reset in the presence of back-moving spring 215.
