The utility model solves the technological scheme that its technical problem adopts:
A kind of rotary-open type damping check valve, comprise the tubular valve body that two-port is arranged respectively to fluid inlet and fluid output, encapsulate flap, rocking bar, the described rocking bar one end be provided with valve seat at described valve body inner fluid suction side, driving described encapsulate flap to be connected with valve seat folding is connected encapsulate flap, the other end is hinged on valve interior wall by rocker shaft, it is characterized in that, on the surface of contact of described encapsulate flap and valve seat, being wholely set evagination O-ring seals with encapsulate flap.
Described rocking bar is wholely set with it axle sleeve through rocker shaft, described axle sleeve is held spaced point of axle sleeve by two and is formed, a torsion spring is set with at the position that described rocker shaft is corresponding with described interval, described one end is pressed on the flap back side, and the other end is stuck in the jump-ring slot that valve interior wall is arranged.
The axis hole that the axle sleeve of described encapsulate flap is arranged is its major axis slotted hole parallel with valve axis.
Described encapsulate flap and rocking bar are sulfidization molding integral pieces.
Described valve body is provided with suspension ring.
The beneficial effects of the utility model are: on encapsulate flap, be wholely set evagination O-ring seals with it, instead of face sealing, improve sealability with linear sealing; Especially turn increase torsion spring, like this, in the pressure of the top of torsion spring elastic force, add the impacting force to encapsulate flap, even if occur that fluid return pressure is too small, also can not produce contact gap, further enhancing the leakproofness of encapsulate flap and valve base chamber surface of contact; Encapsulate flap and rocking bar make sulfidization molding integral piece, not only eliminate nut, packing ring, save goods, materials and equipments, simplified assembling process, improve packaging efficiency, and reduce water hammering, energy-conserving and environment-protective; The utility model is for the integral structure of encapsulate flap and rocking bar, the axis hole that encapsulate flap shaft puts is set to slotted hole, like this, utilize the gap of rocker shaft and axis hole, coincide at elastic force effect lower Disc and contact surface of valve seat energy Automatic Levelling, avoid the assembling defect because machining error causes, guarantee valve seal performance; In addition, described valve body arranges suspension ring, during mounted valve, just with hoist, valve can be sling easily in engineering like this, easy construction, quick.
