Embodiment
Shown in Fig. 1-2; The described maintenance flushing of the utility model embodiment pressure measurement complex hydraulic valve; Comprise valve body 9; Installation dimension on said valve body 9 upper and lower two attachment faces and port size is identical and be contained on the common manifold block by mounting screw, it is identical that this valve body 9 is reserved top one side installation dimension of manifold block below it like this, so just reached the conducting oil circuit; Said valve body 9 both sides are provided with two ball valves respectively; Promptly wherein a side is provided with ball valve 1, ball valve 44; It is all fixing through corresponding locking nut 10 that opposite side then is provided with ball valve 22, ball valve 33 and each ball valve; Be positioned at four oil circuits are set on this valve body 9; Be oil circuit 1, oil circuit 26, oil circuit 37, oil circuit 48 (following also can represent with oil circuit A, B, P, T respectively), these four oil circuits are surrounded on four ball valves through curvilinear style in the shape of a spiral, and each ball valve inside is respectively arranged with spool 11 and is positioned on the circumferential surface of spool 11 perforate 1 is set respectively.For oil circuit around the path; Be specially: oil circuit 1 wherein passes ball valve one 1 inside and walks around ball valve 44 outsides; Oil circuit 26 wherein passes ball valve 22 inside and walks around ball valve 33 outsides; Oil circuit 37 is wherein walked around ball valve 22 outsides and is passed ball valve 33 inside, and oil circuit 48 is wherein walked around ball valve one 1 outsides and passed ball valve 44 inside.
The described maintenance flushing of the utility model embodiment pressure measurement complex hydraulic valve, the different rotary angle for each ball valve inner spool 11 has produced difference in functionality, specifically comprises following:
⑴ as shown in Figure 3, and when the oil circuit of spool 11 up and down during conducting, valve body 9 is in normal mode of operation;
⑵ as shown in Figure 4, and when shown in spool 11 half-twists during position, it closes upper and lower oil circuit; Reach shown in Fig. 1 in the hydraulic schematic diagram function of four ball valves on P, T, A, the B oil circuit: the valve on it needs repairing or when changing, just can the spool 11 on P, T, A, the B oil circuit be rotated to Fig. 4 position, cuts off this four oil circuits; Need not shut down the valve that to pull down above it to be adorned and keep in repair, after fixing, put in back on the maintenance valve; The spool that will turn over just now this moment again goes back to; Be in Fig. 3 position, its four upper and lower conductings of oil circuit get into normal mode of operation;
⑶ after P, two spools of T, 11 simultaneously outside pines move back certain distance, and P, the conducting of T oil circuit reach the function of washing ball valve shown in Fig. 1 in the hydraulic schematic diagram, open this oil circuit, just can play the short circuit washing capacity to this loop;
⑷ as shown in Figure 5, and when spool 11 different rotation angle, this valve just has different throttling function;
⑸ as shown in Figure 2, and for the perforate 1 of spool 11, it draws the nut termination of leading to spool 11 with oil circuit, and blocks with a R1/4 or M10*1 plug, can adorn pressure measuring tie-in or oil pressure flexible pipe here, can monitor the pressure of A, B, P, four oil circuits of T in real time;
