Embodiment Construction

[0041] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples are only used to explain the present invention, but not to limit the scope of the present invention.

[0042] A kind of manual hydraulic switching device for hydraulic valve driving device of the present invention, such as Figure 1-10 As shown, the hydraulic valve driving device has a hydraulic cylinder, and the hydraulic cylinder has two working oil chambers, including a mounting block 1, a handle 2, a rotating member 3 and a rotation positioning mechanism 4 for rotating and positioning the position of the handle 2;

[0043] The handle 2 is located above the mounting block 1 and is rotated to connect the handle 2 and the mounting block 1 through the rotating member 3. The rotating member 3 is provided with a third oil passage 31, and the mounting block 1 is provided with a rotating member 3 that can be converted to communicate with the ...

Abstract

The invention relates to a manual and hydraulic switching device for a hydraulic valve driving device, the hydraulic valve driving device is provided with a hydraulic cylinder, the hydraulic cylinder is provided with two working oil cavities, and the hydraulic cylinder comprises a mounting block, a handle, a rotating piece and a rotary positioning mechanism for fixing the position of the handle; the handle is located above the mounting block, the rotating piece is rotationally connected with the handle and the mounting block, a third oil channel is formed in the rotating piece, a first oil channel and a second oil channel which can be communicated with the third oil channel in a convertible mode are formed in the mounting block, and the first oil channel and the second oil channel are correspondingly communicated with the two working oil cavities respectively; the rotary positioning mechanism is movably connected with the handle, and one end of the rotary positioning mechanism is movably inserted into the mounting block to fix the position of the handle. When the hydraulic cylinder is in a manual mode, the two working oil cavities of the hydraulic cylinder are communicated, no pressure difference exists, the position of a piston in the hydraulic cylinder can be adjusted at will, and therefore manual operation is more convenient; the device is ingenious in structure, manual and hydraulic switching is convenient and fast, reliability is high, and meanwhile manual operation of the hydraulic valve driving device is more labor-saving.

Description

technical field [0001] The invention relates to a hydraulic valve driving device, in particular to a manual hydraulic switching device used for the hydraulic valve driving device. Background technique [0002] The valve driving device is a device used to operate and control the valve and connected with the valve. The purpose of use is to make the operation of the valve labor-saving, convenient and rapid, or to realize automatic control or remote control. Among them, the hydraulic valve driving device is a device that drives the valve to rotate through hydraulic oil. During the manual operation process of the existing hydraulic valve driving device, due to the pressure difference between the two working oil chambers, the manual operation is laborious. [0003] Therefore, how to provide a manual hydraulic switching device that can make the manual operation of the hydraulic valve driving device labor-saving is a technical problem that those skilled in the art need to solve urge...
