Fracturing high pressure manifold quickly separating device

The utility model relates to a quickly separating device of fracturing high pressure manifold, including sealing up the packing, going up valve body, hydro -cylinder seat, to go up valve body one end and connect for the union, the other end has 8 stoppers through the bolt fastening, and the bolt overcoat has the pretension spring, and the spring has certain pretightning force. Down valve body one end connects for the union, and inside the valve body was placed in to the other end, the stopper was overcome spring -load and is impressed in the annular groove at valve body middle part down under the piston action, and the valve body is fixed under the messenger. During switch among the operatable hydraulic control system, hydraulic oil connect to get into the hydro -cylinder from the oil feed, the elasticity that return spring is overcome down in the effect of hydraulic oil pressure to the piston moved to the left side, and the stopper outwards opens under the spring -load effect and loses fixing of under to valve body, and upper and lower valve body can separate.
