Abstract

The invention discloses a tee high-frequency electro-hydraulic exciting vibration valve which comprises a valve body, a valve core and a valve sleeve, wherein the valve body is provided with an oil inlet, an oil outlet and an oil return opening, wherein the oil inlet is communicated with a high-pressure oil tank; the oil outlet is communicated with a hydraulic cylinder; the oil return opening is communicated with an oil return oil tank; the valve core and the valve sleeve are positioned in the valve body; the valve sleeve is embedded in a hole of the valve body; the valve core is positioned in the valve sleeve, and is provided with four shoulders, wherein two shoulders at the outer side are support shoulders, and two shoulders in the middle are operating shoulders; grooves are respectively processed axially on the two operating shoulders uniformly, and the grooves of the two operating shoulders are misplaced mutually; valve sleeve windows which are matched with the grooves of the shoulders are uniformly formed circumferentially on the part of the valve sleeve corresponding to the operating shoulders; the distance between the valve sleeve windows is equal to the distance between two operating shoulders; at least three oil wedges are axially formed on the valve sleeve corresponding to the support shoulders at intervals of equal circular arcs; the oil outlet is communicated with a throttle valve; and the throttle valve is installed on the valve body. According to the invention, the shaft diameter deviation is avoided effectively, and the operating stability is good.

Description

technical field [0001] The invention relates to a high-frequency electro-hydraulic excitation valve. Background technique [0002] The existing high-frequency electro-hydraulic vibration valve includes a valve body, and the valve body is provided with an oil inlet connected to the high-pressure oil tank, an oil outlet connected to the hydraulic cylinder, and a return port connected to the oil return tank. oil port; the valve body contains a valve core and a valve sleeve, the valve sleeve is nested in the hole of the valve body, the valve core is inserted into the valve sleeve, and the valve core is connected with the transmission mechanism through a sleeve coupling; There are shoulders, and a certain number of grooves are evenly opened in the circumferential direction of the shoulders, and the grooves on two adjacent shoulders are misaligned; the positions on the valve sleeve corresponding to the middle two shoulders are uniformly opened in the circumferential direction and ...
