Main functions

Objective

Design and production of a leak-test bench for ball valves. This air-tightness check on valves is carried out at the end of the production line before the products are marketed.

PROBLEMATIC ISSUES

Solution and Result

The proposed equipment is a system for gripping and tightening 1/4-turn valves, with a view to carrying out leak tests with an air injection system equipped with a micro-flow measurement.

For each type of valve, the tooling consists of two identical parts that seal the valve on a flat surface and position the ball valve. The ergonomics of the bench have been optimised, and tooling movements are made using the two buttons on the front of the control console.

The control system (internal PC) has a set of predefined programs depending on the type of valves to be tested. It displays messages on the control panel indicating the various test stages to the operator (identify yourself, identify the product, identify the test programme used, position the valve, open the valve, close the valve, etc).

The Human Machine Interface enables :

To ensure the safety of operators during the leak test phase, an emergency stop button is located on the front of the bench. It activates the engine stop command.

Before being put on the market, all valves undergo air-tightness tests (leakage measurement).

The verification system checks the closing and opening functions of the tool, with controlled tightening. The air injection and leakage measurement system is controlled via specific software using the control panel;
