A flow seat is provided inside the first balance valve seat. An oil pipe interface seat is movably connected to the upper surface of the first balance valve seat. Overflow valve seats are provided on the left and right sides of the first balance valve seat. The outer surface of the first balance valve seat is There is an oil cylinder interface seat on the surface and on the side away from the overflow valve seat. The first balance valve seat includes a force-bearing arc plate. A pressure-reducing spring is movably connected to the inside of the force-bearing arc plate. The upper surface of the force-bearing arc plate A telescopic pressure shaft is movablely connected, and a force-bearing spring seat is provided inside the telescopic pressure shaft. A balance valve installation hole is provided on the outer surface of the connecting column. A second balance valve seat is provided on the surface of the connecting column and inside the balance valve installation hole. In When used, it solves the problem of excessive impact on the balance valve seat when the oil line pressure is too high, protects the balance valve group, and ensures the normal flow of hydraulic oil.
Telescopic arm luffing balance valve, including external telescopic cylinder, first oil inlet, second oil inlet, first oil outlet, second oil outlet, balance valve, pilot port, hydraulic control valve, relief valve and Damping hole, the first end of the balance valve is connected to the second oil inlet, the second end of the balance valve is connected to the second oil outlet, the third end of the balance valve is connected to the pilot port, the first oil inlet is connected to the first oil outlet, and the hydraulic control The first end of the valve is connected to the connecting oil line between the first end of the balance valve and the second oil inlet, the second end of the hydraulic control valve is connected to the connecting oil line between the third end of the balance valve and the pilot port, and the third end of the hydraulic control valve is connected to the first The oil inlet is connected to the first oil outlet. The first oil outlet is connected to the rod cavity of the external telescopic oil cylinder, and the second oil outlet is connected to the rodless cavity of the external telescopic oil cylinder. The telescopic arm provided by the utility model The forklift luffing balance valve is not affected by the load when the amplitude is luffed. The relief valve and the damping hole work together to ensure that the luffing balance valve is in a stable working condition.
