The combination valve is fixedly connected with cluster spring piece by the moving block on the inside of which, and cluster spring piece
One end is fixedly connected through the outlet of plunger with the fixed block being arranged on plunger outer wall, is also pacified on the right flank of combination valve
Equipped with hydraulic cylinder is installed with the right side of pressure sensing, and pressure sensor, hydraulic cylinder is slided with hydraulic motor by connecting rod
Dynamic connection, the hydraulic cylinder are provided with valve bonnet by slide.
Used as a kind of preferred technical scheme of the utility model, the inner surface of the bent axle is installed with bearing shell, bearing shell
Connecting rod is connected with by connecting bolt.
Used as a kind of preferred technical scheme of the utility model, the right-hand member of the connecting rod is also installed with crosshead pin,
And crosshead pin is embedded on the inwall of seal box.
As a kind of preferred technical scheme of the utility model, intermediate bar is provided with by oil sealing on the O-ring, and
The left end of intermediate bar is connected on seal box.
Compared with prior art, the beneficial effects of the utility model are：The plunger type water injection pump, by arranging magnetic device,
Promote fuselage to rotate under the drive of bent axle, transmission device is automatically opened up, pressure sensor is set, open bent axle
When, can drivening rod slide in and out, and the valve that is connected not only makes the convenient movement of connecting rod, and makes plunger more
Plus convenient transmission pressure, the relative minimizing of water injection pressure is made, cluster spring piece is installed on combination valve, combination valve can be made to perceive pressure
Power, can effectively reduce machine and damage because pressure-bearing is overweight.
