Description

Technical Field

[0001] The utility model relates to the technical field of proportional relief valves, in particular to a novel high-temperature pressure-regulating proportional relief valve. Background Art

[0002] A proportional relief valve is a hydraulic control valve that can change the parameters (pressure) of the output oil proportionally with the changes in the parameters of the input electrical signal (current or voltage). This type of valve works in conjunction with an electronic amplifier, which provides an appropriate drive current to the proportional valve to calibrate the valve adjustment to correspond to the input signal supplied to the amplifier. As an important remote pressure regulating component, the allowable temperature of the proportional relief valve generally does not exceed 80 degrees Celsius.

[0003] However, the existing proportional relief valve is greatly affected by the temperature of the oil flowing through it during use. Under the influence of the high temperature of the oil for a long time, it is easy to cause working failure and damage to internal components, which seriously reduces the overall service life.

[0010] As a preferred solution, an output pipe is fixedly installed at the output end of the valve body, and a rubber pad is fixedly connected to the right side of the output pipe.

[0011] As a preferred solution, a filling pipe is fixedly connected to the upper end of the front surface of the cooling box, and a sealing cover is threadedly connected to the front surface of the filling pipe.
