CHECK VALVE AND PUMPING SYSTEM |
| 摘要 |
A check valve (100) has a valve seat (20), and a valve disc (30) which closes the valve seat (20) in an openable/closable manner by linear reciprocating oscillation in the direction approaching or departing away from the valve seat (20), the check valve (100) being configured, as a lift-type check valve, to allow therein the inflow direction (D1) of a fluid (F) flowing into the valve seat (20) and the passing direction (D2) of the fluid (F) passing through the valve disc (30) to cross each other, the valve disc (30) being provided with, on the inflow side (primary side) thereof, a deflection surface (40) on which the fluid (F) is deflected from the inflow direction (D1) to the passing direction (D2). |

1. A lift-type check valve comprising a valve seat, and a valve disc which closes the valve seat in an openable/closable manner by linear reciprocating oscillation in the direction approaching or departing away from the valve seat, being configured to allow therein the inflow direction of a fluid flowing into the valve seat and the passing direction of the fluid passing through the valve disc to cross each other,
the valve disc being provided with, on the inflow side thereof, a deflection surface on which the fluid is deflected from the inflow direction to the passing direction. |
