Abstract

The invention discloses a combined valve for a reciprocating pump. The combined valve comprises a valve seat, an outlet valve component and an inlet valve component, the outlet valve component and the inlet valve component are horizontally mounted at two ends of the valve seat respectively, the outlet valve component comprises an outlet valve, an outlet valve gland, an outlet valve guide sleeve and an outlet valve spring, and the inlet valve component comprises an inlet valve, an inlet valve gland and an inlet valve spring. Parts of the combined valve can be assembled easily and compactly, so that structural space demand is small; the combined valve is simple and convenient to mount and demount, stable in structure, high in volume efficiency, working efficiency and pressure bearing capacity and long in service life.

Description

technical field [0001] The invention relates to the technical field of pump valves for water pumps, in particular to a combination valve for reciprocating pumps. Background technique [0002] The inlet and outlet valve of the reciprocating pump is one of the important parts of the pump operation, and it is also one of the most important wearing parts in the reciprocating pump. The quality of its design will affect the working performance and service life of the pump. As the main part of the hydraulic end, the inlet and outlet valves are installed in the cylinder of the pump head, and its structure plays a decisive role in the volumetric efficiency of the pump, the volume of the cylinder of the pump head and the difficulty of maintenance. Compared with reciprocating pumps with other pump and valve structures, the reciprocating pump with horizontal combination valve has the characteristics of easy maintenance and relatively compact structure of the pump head. [0003] However...
