A throttle device for a boiler high-pressure feed pump

Abstract

This utility model discloses a throttling device for a boiler high-pressure feedwater pump, relating to the field of high-pressure feedwater pump technology. It includes a housing and pipes. The pipes are fixedly connected to one side wall of the housing. A first inlet pipe, a second inlet pipe, a first outlet pipe, and a second outlet pipe are respectively fixedly inserted into the two side walls of the housing. The distances from these pipes to the main pipe, from closest to farthest, are: first inlet pipe, first outlet pipe, second inlet pipe, and second outlet pipe. This utility model uses a motor to drive a rotating wheel, which in turn drives a piston to move, dynamically changing the number of inlets and outlets that are open. This allows for flexible adjustment of the pump flow rate, meeting the precise flow control requirements under different operating conditions, solving the problem of the flow rate not being able to be arbitrarily changed, and improving the applicability of the throttling device.
