Detailed Description

The arrow type check valve is installed between the drill pipe and the drill bit for preventing the backflow of the drilling fluid from the shaft bottom. Its body is a conversion connector, and other parts are installed in the inner hole of the connector. When the backflow occurs, the arrow type valve core can tightly compact the valve base, so the fluid can not flow upwards through the check valve. When the drilling fluid normally circulates, the arrow type valve core falls on the lower support, the drilling fluid can pass through the check valve without pressure drop.
