And through the setting of guiding gutter make the guide part when not separating with flowing back passageway, can realize switching on of liquid through the guiding gutter, guarantee spacing prerequisite like this, can ensure the steady removal of flowing back case.
Further setting the following steps: an annular flow guide ring surrounding the circle center of the guide part is arranged between the outer peripheral wall of the guide part and the liquid discharge valve core, the flow guide ring is communicated with the flow guide groove, and the position, close to the flow guide ring, of the outer wall of the liquid discharge valve core is matched with the valve seat to form sealing.
Through adopting above-mentioned technical scheme, the area of contact of sealed face between setting up increase liquid and flowing back case and the disk seat of water conservancy diversion ring for liquid passes through the water conservancy diversion ring and can applys even effort to sealed face, thereby realizes better separation between disk seat and the flowing back case between the two and this kind sets up and makes the flowing back case when moving back to the disk seat, can ensure its removal precision.
Further setting the following steps: one end of the liquid drainage channel, which is close to the liquid drainage valve core, is excessively inclined to form a first sealing inclined surface with an outward flaring, and a second sealing inclined surface matched with the first sealing inclined surface is arranged on the liquid drainage valve core.
Through adopting above-mentioned technical scheme, better supporting tight seal can be realized to the cooperation between first sealed inclined plane and the sealed inclined plane of second to promote the sealed grade of flowing back case.
Further setting the following steps: one end of the liquid suction channel, which is back to the liquid discharge valve core, gradually inclines towards the liquid discharge channel, so that the liquid suction channel forms an inclined arrangement, and one end of the liquid suction channel, which is close to the liquid discharge valve core, penetrates through the peripheral wall of the valve seat.
Through adopting above-mentioned technical scheme, the imbibition passageway that sets up through the slope reduces the effort that the liquid through imbibition passageway applyed to the high-pressure cylinder liner inner wall, makes the operation of hydraulic end mechanism more stable, life is longer.
Further setting the following steps: the periphery wall of the valve seat is provided with spiral grains.
Through adopting above-mentioned technical scheme, the convenient installation that can realize the disk seat of setting up of spiral line and this kind of mounting means has very high leakproofness.
Further setting the following steps: one end of the liquid discharge channel, which is back to the liquid discharge valve core, is gradually expanded outwards to form an inclined guide surface.
Through adopting above-mentioned technical scheme, the setting of slope guide face plays better guide effect to the liquid through flowing back passageway, and better guide liquid enters into flowing back passageway to reduce the impact of liquid to the disk seat.
To sum up, the utility model discloses following beneficial effect has: the utility model discloses have bigger suction capacity and design stable in structure, still have higher sealing performance.
