Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.
The first embodiment is as follows:
as shown in fig. 1-3, the utility model discloses a throttle valve testing tool for a fuel booster and an exhaust valve, which comprises a tool body, wherein the tool body is connected with an oil duct respectively connected with a pressure regulating valve and a tested throttle valve in parallel, the tool body is also provided with a connecting port for connecting an oil pump, the connecting oil duct of the connecting port and the pressure regulating valve is provided with a pressure gauge, and the connecting oil duct of the connecting port and the throttle valve is provided with an energy accumulator.
The top surface of the tool body is provided with a pressure gauge and a pressure regulating valve, and the pressure regulating valve is connected with an oil duct in the tool body through an outer pipeline.
The oil pressure gauge is used for monitoring and adjusting the system pressure and observing the pressure when the throttle valve is opened, and can also be replaced by a pressure sensor and an intelligent instrument, so that the system precision is higher and more intelligent; the pressure regulating valve is used for regulating the pressure of hydraulic oil in the system and can be a manual pressure regulating valve or an electric control proportional pressure regulating valve; the connecting port and the threaded hole for connecting the throttle valve to be tested are oppositely arranged on two sides of the tool body, wherein the connecting port is used for connecting an oil pipe between the oil pump and the testing tool and can be a flange interface or a threaded interface in any form; the side surface of the tool body is also provided with an energy accumulator; the accumulator may be a gas-filled or spring-loaded accumulator, and is used to store and stabilize the hydraulic energy output by the oil pump.
An extension plate is arranged at the bottom of the tool body, and a bolt for fixing the tool body is arranged on the extension plate; taking a 60ME-C model as an example, after the throttle valve testing tool is fixed on a bench worker workbench, a throttle valve 3 to be tested is installed in a threaded hole 7 of a testing tool body 1;
connecting an outlet of an oil outlet pipe of the hydraulic device 2 to a connecting port 8 of an inlet of the tool body 1, and simultaneously confirming that the oil level of hydraulic oil in an oil tank of the oil pump is within an allowable range;
