Description

Load valve module

Technical Field

The utility model relates to a valve body technical field specifically is a load valve module.

Background

The speed regulating valve is a combined valve formed by connecting a fixed-differential pressure reducing valve and a throttle valve in series. The throttle valve is used for adjusting the flow passing through, and the constant-differential pressure reducing valve automatically compensates the influence of load change, so that the differential pressure before and after the throttle valve is a constant value, and the influence of the load change on the flow is eliminated.

The pressure in front of and behind the throttle valve is respectively led to the right end and the left end of the valve core of the pressure reducing valve, when the load pressure is increased, the hydraulic pressure acting on the left end of the pressure reducing valve core is increased, the valve core moves to the right, the pressure reducing port is increased, the pressure drop is reduced, and therefore the pressure difference of the throttle valve is kept unchanged, and vice versa. Thus, the flow of the speed regulating valve is constant (is not influenced by load). The speed regulating valve can also be designed into a structure of throttling and then reducing pressure;

however, the load effective adjustment can not be realized by the speed regulating valve alone, the traditional load adjusting system is complex, the integration degree is low, and the use is inconvenient, so that the inventor provides a load valve module by integrating various factors.
