Embodiment
[0024] The total pressure of the hydraulic system is 30 kg. The hydraulic pressure in a certain branch route is adjusted to 28 kg according to the needs. Before the total pressure needs to be adjusted to 25 kg, it may meet the 28 kg pressure requirement of the branch route. If the total pressure is adjusted to 25 kg , The pressure and working characteristics of other branch routes are also greatly affected.
[0025] But now, on the branch line that needs to be adjusted to 28 kilograms of pressure, the product of the present invention can be directly inserted into the branch line to adjust the pressure on the branch line to 28 kilograms, and the adjustment speed is more than 5 times faster than the previous method of adjusting the total pressure, and The pressure of other branch routes is not affected, and the working characteristics are not affected.

The invention discloses a work feeding pressure adjusting valve which comprises a cartridge valve and a transition part. The cartridge valve is in drive fit with the transition part. The cartridge valve comprises a cartridge valve body, and a work feeding pressure adjusting valve element located in the cartridge valve body. The middle portion of the cartridge valve body is cooperatively provided with an oil return opening. An oil inlet is cooperatively formed in the position, on the lateral lower side of the position opposite to the oil return opening, of the cartridge valve body. An angle of 90 degrees is formed between the oil return opening and the oil inlet. A cartridge valve gear is cooperatively arranged at the upper portion of the work feeding pressure adjusting valve element. The transition part comprises a transition shaft, a connecting seat, a transition gear and a transition shaft valve body. The transition shaft sequentially penetrates the connecting seat, the transition gear and the transition shaft valve body. The transition gear is matched with the cartridge valve gear to rotate. The work feeding pressure adjusting valve is a novel branch pressure regulating device of a hydraulic system, the hydraulic pressure intensity in a certain branch circuit can be adjusted through the work feeding pressure adjusting valve under the condition that the total pressure intensity of the hydraulic system is not adjusted, and therefore the work requirement can be met.
Description
technical field [0001] The invention relates to a working pressure regulating valve. Background technique [0002] The function of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components and hydraulic oil. Hydraulic systems can be divided into two categories: hydraulic transmission systems and hydraulic control systems. The main function of the hydraulic transmission system is to transmit power and motion. The hydraulic control system must make the output of the hydraulic system meet specific performance requirements. The hydraulic system usually refers to the hydraulic transmission system. The function of the power element of the hydraulic system is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire h...
