Abstract

The invention relates to a plunger pump valve bank which comprises a valve seat. The plunger pump valve bank is characterized in that liquid inlet cavities are formed in the outer wall of the valve seat, the two end faces of the valve seat are both planes, the plane at one end of the valve seat is the liquid inlet plane, and the plane at the other end of the valve seat is the drainage plane; the liquid inlet plane is provided with an annular groove communicating with the liquid inlet cavities; a liquid inlet valve plate is arranged outside the liquid inlet plane of the valve seat and provided with liquid inlets, and a sealing surface is located between the outer edge of the liquid inlet valve plate and the outer edge of the liquid inlet plane; the liquid inlet plane is provided with drainage cavities, and the drainage cavities and the annular groove are arranged at intervals; the drainage plane is provided with liquid outlet cavities, and drainage channels enabling the drainage cavities and the liquid outlet cavities to communicate are formed in the valve seat; a drainage valve plate is arranged outside the drainage plane of the valve seat and provided with drainage holes, and a sealing surface is located between the outer edge of the drainage valve plate and the outer edge of the drainage plane. The plunger pump valve bank provided by the invention is small in size, high in pump efficiency and capable of effectively lowering the valve play flow rate.

Description

technical field [0001] The invention relates to a plunger pump valve group. Background technique [0002] The main components of the reciprocating plunger pump are power, hydraulic power and power source. The main power components are crankshaft, fuselage, connecting rod, crosshead and connecting rod. The main hydraulic components are the pump body, the box body, the plunger, the packing, the guide sleeve, the inlet and outlet valve groups, the inlet and outlet water collectors, and the drainage components. The power source is composed of electric motor (diesel engine), reducer (transmission pulley, transmission belt), shield, base and so on. The reciprocating plunger pump is a positive displacement pump with high pressure, small flow and high efficiency. Under the condition of the same power, the pressure is high and the flow rate is small. On the contrary, the flow rate is large and the pressure is small. The power mechanism is basically similar, and the hydraulic mecha...
