A Manufacturing Method of Hydraulic Mechanism with Manual Pneumatic Actuator
The utility model relates to a hydraulic mechanism with a manual pneumatic actuator, which comprises a hydraulic cylinder, a balance valve, a paddle, a manual pump, a cylinder head, a fuel tank, a piston rod, a handle and a cylinder. The piston rod is installed below the cylinder, there is an oil tank in front of the cylinder, there is a manual pump above the oil tank, there is a paddle on one side of the manual pump, one end of the paddle is connected with a handle, the cylinder head is installed on the upper surface of the cylinder, the oil tank is fixed on one side of the cylinder head, there is a hydraulic cylinder in the middle above the cylinder head, there are four hydraulic outlets on the hydraulic cylinder, two hydraulic outlets are connected through a pipe, and a balance valve is set in the middle of the pipe, The other two hydraulic outlets are connected to both sides of the manual pump.
When installing the fuel tank, the fuel filler must face upward.
The piston rod of the hydraulic cylinder extends into the cylinder and is fixed between the cylinder pistons with a fixing block. It moves axially and does not affect each other radially.
The hydraulic cylinder is a closed structure.
Whether there are oil bearings and sealing rings between the piston rod of the hydraulic cylinder and the cylinder head. After being stretched into the cylinder, the cylinder is also sealed.
Compared with the prior art, the utility model has the following beneficial effects:
When the pneumatic device fails, the utility model can freely switch to the manual state. The valve is closed or opened by hydraulic principle, which is convenient for manual switching, safe and reliable, and easy to operate.
The hydraulic piston rod of the hydraulic cylinder extends into the cylinder and is fixed with a fixed block with the cylinder piston. It moves axially and does not affect each other radially.
The hydraulic cylinder is sealed. There are oil bearings and sealing rings between the hydraulic piston rod of hydraulic cylinder 1 and cylinder head 5. After extending into the cylinder, the cylinder is also sealed.
Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in the art that these embodiments can be changed, modified, replaced and changed without departing from the principle and spirit of the utility model. The scope of the utility model is limited by the appended claims and their equivalents.
