Embodiment Construction

[0036] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0037] The structure of the hydraulic valve with independent control of the load throttle port proposed by the present invention is as attached figure 2 As shown, it includes a hydraulic valve body 1 , a valve core 9 and a displacement sensor 14 .

[0038] A left control port 2 and a right control port 3 are designed on the hydraulic valve body 1, and the valve core 9 can be controlled to slide left and right in the valve body 1 by passing hydraulic oil with a certain pressure into the two control ports. When the pressure in the left control port 2 is higher than the pressure in the right control port 3, the spool 9 moves to the right under the action of the pressure difference, otherwise the spool 9 moves to the left, when the pressures in the two control ports are equal , the spool 9 stops moving.

Abstract

The invention discloses an energy-saving hydraulic valve with independently-controllable load throttle mouths. A spool (9) of the hydraulic valve is provided with a displacement sensor (14). Two protruding shoulders (11 and 12) in the middle of the spool (9) and two load throttle mouths (6 and 7) satisfies the following conditions: when one of the protruding shoulder controls openness of one load throttle mouth, the other load throttle mouth is fully opened. No mutual interference occurs between the two load throttle mouths of the hydraulic valve, the two load throttle mouth can work independently, and energy-saving control of the hydraulic valve system is achieved.

Description

technical field [0001] The invention relates to the technical field of fluid transmission and control, in particular to an energy-saving hydraulic valve with independent control of a load throttle and an energy-saving hydraulic valve control system using the hydraulic valve. Background technique [0002] In traditional hydraulic valve-controlled systems (such as hydraulic valve-controlled cylinders and hydraulic valve-controlled motors), the two load orifices of hydraulic valves are mechanically connected. When the opening degree of one of the load throttling ports is controlled, the opening degree of the other load throttling port is also determined accordingly, that is, the opening degrees of the two load throttling ports are always the same. The role of load throttling is to adjust the hydraulic oil with higher pressure before entering the throttle port into hydraulic oil with lower pressure, so as to obtain hydraulic energy that meets the demand. The pressure difference...
