Description of drawings
Fig. 1 is the layout sketch map of the utility model excavator with the horizontal main valve revolution of two revolutions pipeline.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but not as the qualification of the utility model.
Please referring to shown in Figure 1; The utility model excavator is with the horizontal main valve revolution of two revolutions pipeline; Wherein horizontal main valve 0 is placed on the main valve frame 1; Comprise that some sebific ducts, the first revolution pipeline 2, the second revolution pipeline 3, first fen oil clot 4 and 5, the first fens oil clots 4 of second fen oil clot and second fen oil clot 5 are one-in-and-two-out and divide oil clot.The first revolution pipeline, 2 one ends connect a main valve hydraulic fluid port 6; The other end connects first fen oil clot 4 inlet; 4 outlets of first fen oil clot are connected with two rotary motors, 8 main hydraulic fluid ports over against main valve frame 1 through two 7 in some sebific ducts, 7 '; The second revolution pipeline, 3 one ends connect another main valve hydraulic fluid port 9; The other end connects second fen oil clot 5 inlet, and oil clot 5 outlets in second fen are connected with two rotary motors, 8 main hydraulic fluid ports over against main valve frame 1 through other two 10 in some sebific ducts, 10 ', and first turns round pipeline 2 and second turns round pipeline 3 and all passes through from main valve frame 1 below.
