Handheld debugging instrument

Abstract

The invention provides a handheld debugging instrument, which belongs to the technical field of instruments, and solves the problem that the existing balance valve is lack of an appropriate debugging device. The handheld debugging instrument is used for debugging a valve in a pipeline and comprises a shell which can be held by a hand, a controller, a power supply, a display control module and a pressure difference sensor, wherein the controller and the power supply are arranged inside the shell, the display control module is connected to the outer surface of the shell and can be used for displaying and inputting an operation order, the pressure difference sensor can detect the pressure difference between a water inlet and a water outlet of the valve, the power supply, the display control module and the pressure difference sensor are connected with the controller, the controller can receive the circulation capacity information of a debugged valve, inputted by the display control module, and the pressure difference information of the valve, transmitted by the pressure difference sensor, and calculates the flow at the valve, and the controller controls the display control module to display the flow value. The handheld debugging instrument has the advantages of convenience in carrying and operation, precise measurement result and function diversity.

Description

technical field [0001] The invention belongs to the technical field of instruments and meters, and relates to a debugging instrument, in particular to a hand-held debugging instrument capable of debugging a valve arranged in a pipeline. Background technique [0002] The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Among them, the balance valve is used in the water system that requires flow control. As long as it is adjusted once before operation, the system flow can be automatically constant at the required set value. It is suitable for non-corrosive liquid media such as heating and air conditioning. flow con...

AI Technical Summary

Problems solved by technology

However, there is currently a lack of relevant debugging equipment. For example, installing flowmeters at each balance valve is not only costly, but each flowmeter is easily damaged when exposed to the outside, and the portable ultrasonic flowmeter is easily affected by the wall thickness of the pipeline under test The problem that the flow rate cannot be accurately measured due to the influence of factors such as pipe wall material and so on
