Preferably, the oil through is provided with more than one, the pressure regulation efficiency of pressure regulator valve can be improved.
Preferably, the oil through is around 360 ° of the first valve body front end equidistant arrangement, pressure oil can be even into the One valve inner so that the pressure regulation of pressure regulator valve is more stablized.
Preferably, the spout hole is provided with more than one, the pressure regulation efficiency of pressure regulator valve can be improved.
Preferably, being to be detachably connected between first valve body and the second valve body.
Pressure regulator valve principle:When operating pressure exceedes the pressure of factory setting in hydraulic system, pressure oil can pass through first The oil through of valve body front end enters the first valve inner, and pressure oil pushes pressure regulation top cylinder open, then is flowed out by spout hole, finally flows Oil return box, realizes the pressure regulation of hydraulic system.
The beneficial effects of the utility model are:The lifting valve of the pressure-adjustable is by being provided with pressure regulator valve, and the pressure regulator valve can spirit The pressure oil pressure of regulation lifting valve living, it is safe.In addition, oil through and spout hole are provided with more than one, Ke Yiti The pressure regulation efficiency of high pressure regulator valve;Oil through is around 360 ° of the first valve body front end equidistant arrangement, and pressure oil can be even into first Valve inner so that the pressure regulation of pressure regulator valve is more stablized.
