Tunnel type outer diameter measuring device for valve rod

Abstract

The invention relates to the technical field of valve rod outer diameter measurement, in particular to a tunnel type outer diameter measuring device for a valve rod, which comprises a mounting plate, and a folding supporting mechanism is fixedly arranged on the bottom side of the mounting plate; the measuring table is arranged above the mounting plate, a limiting clamping mechanism is fixedly arranged on the inner side of the measuring table, a mounting frame is fixedly arranged on the top side of the measuring table, and an outer diameter measuring device is fixedly arranged on the inner side of the mounting frame; a controller; a display; the storage battery, the controller and the displayer are located at one end of the top side of the mounting plate, the storage battery is detachably connected to the bottom side of the mounting plate, and the controller and the displayer are electrically connected with the storage battery through wires. The tunnel type outer diameter measuring device for the valve rod is convenient to fold, store and move, is provided with a protection mechanism, and is high in measuring efficiency and applicability; and installation, placement and measurement of the valve rod are facilitated.

Description

technical field [0001] The invention relates to the technical field of measuring the outer diameter of a valve stem, in particular to a tunnel-type outer diameter measuring device for a valve stem. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. The valve is the control component in the fluid delivery system, with the functions of cut-off, regulation, flow diversion, reverse flow prevention, pressure stabilization, diversion or overflow pressure relief, etc. Features. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems. There are various types and specifications. Valves can be used to control air, water, steam, various ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the valve stem in the prior art often needs to use an outer diameter measuring device to measure the outer diameter of the valve stem. The existing outer diameter measuring device has low working efficiency and can only measure one at a time. , and can only move in one direction, the measuring device is too large, it is troublesome to carry, it is not easy to carry and use, it does not have a protection mechanism, and it is not portable, and a tunnel-type outer diameter measuring device for valve stems is proposed
