Abstract
The invention discloses a hydraulic gate valve. A valve seat and a gate plate are installed in a valve body, a valve frame is installed at the top of the valve body, the top of the gate plate is connected with the bottom end of a piston rod, the top of the piston rod is connected with a piston, the piston is installed in a cylinder body, the cylinder body is fixedly installed on the valve frame, hydraulic pipes are arranged at the top and the bottom of the cylinder body and are connected with an outlet of a hydraulic pump, a reversing valve is arranged at the intersection of the hydraulic pipe at the top of the cylinder body and the hydraulic pipe at the bottom, and an overflow valve is arranged at the outlet of the hydraulic pump. The hydraulic gate valve is reliable in structure, rapid to turn on/off, large in driving force, capable of decreasing flushing of silt to a valve seat hard seal and small in pressure loss.
Description
technical field [0001] The invention relates to the field of valves, in particular to a hydraulic gate valve. Background technique [0002] A valve (famen) is a control component in a fluid delivery system, with functions such as cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, diversion or overflow pressure relief. [0003] Valves for fluid control systems, from most Simple There are quite a variety of varieties and specifications of various valves used in various globe valves to extremely complex automatic control systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. [0004] The control of the valve can adopt a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electro-hydraulic, electro-hydraulic, gas-hydraulic, spur gear, bevel gear drive, etc.; can be driven ...
