Abstract

The invention discloses a single valve core rotation type hydraulic valve driven by a single motor and relates to the technical field of fluid transmission and control technologies. The single valve core rotation type hydraulic valve driven by the single motor is used to solve the problems that a single valve core hydraulic valve in the prior art cannot have multiple functions and is complex in structure and poor in reliability. The hydraulic valve comprises an angular displacement sensor, a motor, a valve body, a valve core, a pressure sensor, a spring collar, a pressing cover and a controller. The motor rotates to drive the valve core to rotate, the valve core rotates to enable a first through hole to be communicated with an oil return T through hole, or a U-shaped groove is communicated with a working B through hole and a pressure P through hole, or a second through hole is communicated with a working A through hole. The controller obtains angle information through the angular displacement sensor 101 or obtains pressure information through the pressure sensor, and thus functions of a reversing valve and functions of a pressure valve can be achieved.

Description

technical field [0001] The invention relates to the technical field of fluid transmission and control, and more specifically relates to a single-spool rotary hydraulic valve driven by a single motor. Background technique [0002] In the prior art, the single-spool hydraulic valve can only realize a single control mode, and cannot realize multiple different control modes on the same valve body, and has a single function; the existing single-spool hydraulic valve cannot directly realize multiple controls through the rotation of the spool Way. [0003] To sum up, the single-spool hydraulic valve in the prior art has the problem that one valve cannot be used for multiple purposes, and that multiple control modes cannot be realized directly through the rotation of the spool. Contents of the invention [0004] The embodiment of the present invention provides a single-spool rotary hydraulic valve driven by a single motor, which is used to solve the single-spool hydraulic valve i...
