Abstract

The invention relates to the technical field of valves, in particular to a throttle valve and a hydraulic system. The throttle valve includes a valve body and a valve element; the two ends of the valve body are provided with a first valve port and a second valve port, the valve element includes a first end portion adjacent to the first valve port, a second end portion adjacent to a second valve port and a main body portion, and the valve element is provided with a throttle passage; when liquid flows from the first valve port to the second valve port, the second end portion can abut against the second valve port, one end of the throttle passage is in communication with the first valve port through an inner cavity of the valve body, and the other end of the throttle passage is in communication with the second valve port; and when the liquid flows from the second valve port to the first valve port, the first end portion can abut against the first valve port and seal the first valve port. The hydraulic system includes the above throttle valve. According to the throttle valve and the hydraulic system, throttle of the liquid flowing from the first valve port to the second valve port can be carried out, the liquid flowing from the second valve port to the first valve port can be blocked, and the compactness is further improved easily.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a throttle valve and a hydraulic system. Background technique [0002] The throttle valve is a valve that controls the flow of liquid by changing the throttle section or throttle length. At present, there are mainly two types of throttle valves used in hydraulic systems. The first type is a two-way throttle valve. The orifice on the two-way throttle valve flows out, that is, the two-way throttle valve can play a two-way throttling effect on the liquid; the second is a one-way throttle valve, when the liquid passing through the valve body flows in a specific direction, the liquid It can only flow out from the orifice of the one-way throttle valve to throttle the liquid, and when the liquid flows in the opposite direction to the specific direction, the one-way throttle valve opens without any throttling of the liquid Function, that is, the one-way throttle valve can only play a on...
