A synchronous action shaft flow distribution switch reversing multi-way valve

Abstract

The invention relates to a synchronous action shaft flow distribution switch reversing multi-way valve. The shaft flow distribution switch reversing multi-way valve is a rotary valve structure, including a shaft flow distribution valve body stator and a shaft flow distribution valve body stator which is rotatably installed on the shaft flow distribution valve through clearance fit. The axial distribution valve core rotor in the body stator, the axial distribution valve body stator and the axial distribution valve core rotor are separated into three sealing areas by four sealing rings arranged in sequence from top to bottom, which is used to realize multi-channel The first sealing area for switch reversing, the second sealing area for oil supply on-off and the third sealing area for oil return on-off. A plurality of circular grooves are not connected to each other in the circumferential direction, and the second sealing area and the third sealing area are grooved in the entire circumferential direction. Compared with the prior art, the invention has the advantages of compact and simple structure, convenient adjustment, large flow capacity, simultaneous oil supply / return of multiple actuators, and high repeatability.

Description

technical field [0001] The invention relates to the technical field of fluid control, in particular to a synchronously acting axial distribution switch reversing multi-way valve. Background technique [0002] Conventional switch electromagnetic reversing valve, the structure of the double-coil solenoid valve mainly includes: lock nut + electromagnetic coil + core tube + spring + gasket + valve core + valve body + gasket + spring + core tube + electromagnetic coil + The structure of the lock nut; the structure of the single-coil solenoid valve mainly includes: lock nut + electromagnetic coil + core tube + spring + gasket + valve core + valve body + gasket + spring + end cover; power supply voltage type It can be divided into DC and AC. The power supply voltage value can be selected in a wide range. The movement of the valve core in the valve body is mainly supported by the hydraulic oil film. The coil is in the energized state for a long time, and the spool is easy to get st...

[0002] Conventional switch electromagnetic reversing valve, the structure of the double-coil solenoid valve mainly includes: lock nut + electromagnetic coil + core tube + spring + gasket + valve core + valve body + gasket + spring + core tube + electromagnetic coil + The structure of the lock nut; the structure of the single-coil solenoid valve mainly includes: lock nut + electromagnetic coil + core tube + spring + gasket + valve core + valve body + gasket + spring + end cover; power supply voltage type It can be divided into DC and AC. The power supply voltage value can be selected in a wide range. The movement of the valve core in the valve body is mainly supported by the hydraulic oil film. The coil is in the energized state for a long time, and the spool is easy to get stuck, causing the actuator to fail; and due to the limited installation space, the size of the coil will limit its maximum holding force, affecting its output power characteristics, and the fluid flows through the spool / valve The cavity formed by the body, the hydraulic power generated also limits the flow capacity of the conventional switch electromagnetic reversing valve; the size of the coil also affects its heat dissipation characteristics, and it is easy to burn the coil in a high temperature or high humidity environment. The way of electrical connection affects its waterproof level;
