工作原理： working principle:

步骤一、第一手动油泵1工作给单向节流式平衡阀B口供压力油，调整第一手动油泵1和第一压力表2，将油压调整至25MP并保压5分钟，观察第一压力表2油压变化，如压力表有回落，则单向节流式平衡阀内部漏油，在出油口能看到油液溢出。 Step 1. The first manual oil pump 1 works to supply pressure oil to port B of the one-way throttling balance valve. Adjust the first manual oil pump 1 and the first pressure gauge 2. Adjust the oil pressure to 25MP and keep the pressure for 5 minutes. Observe the first The oil pressure of pressure gauge 2 changes. If the pressure gauge falls back, the one-way throttling balance valve is leaking oil, and oil overflow can be seen at the oil outlet.

步骤二、第二手动油泵6工作给单向节流式平衡阀X口供压力油，将单向节流式平衡阀内单向阀打开使B口压力油流向A口回油箱，第一压力表2回零，X口压力卸掉后重复步骤一操作判断单向节流式平衡阀漏油故障。 Step 2. The second manual oil pump 6 works to supply pressure oil to the X port of the one-way throttling balance valve. Open the check valve in the one-way throttling balance valve so that the pressure oil from the B port flows to the A port and returns to the oil tank. The first pressure Return gauge 2 to zero, remove the pressure at port X and repeat step 1 to judge the oil leakage fault of the one-way throttling balance valve.
