How To Find The Cause Of Air Leak Of CAMOZZI Solenoid Valve

Author:QINSUN Released in:2023-04 Click:123

Finding the cause of air leakage from the CAMOZZI solenoid valve

The main reason for air leakage from the CAMOZZI solenoid valve is the impact of gasket wear on the valve.

CAMOZZI valve leakage is divided into two types: internal leakage and external leakage. Internal leakage mainly affects the function of the valve. External leakage not only causes the loss of medium, but also causes accidents to the surrounding equipment and personnel, and pollutes the environment. Great impact.

There are two major leakage parts of the CAMOZZI valve, one is the leakage at the connection flange between the valve body and the bonnet, and the other is the leakage at the gasket. The connecting flange between the valve body and the bonnet is sealed by tightening the bolts and compressing the gasket. The reasons for the leakage are as follows:

The tension of the bolts is reduced by thermal shock, causing The preload force of the bolt toout is not sufficient, or the bolts are not evenly tightened.

The hardness of the gasket is higher than that of the flange, or the contact between the gasket and the flange connection surface is not strict due to aging failure or mechanical vibration.

The precision of the contact surface is low (with grooves, scratches, etc.) and it is corroded or leaked by the medium. The packing is bent during assembly and the local preload force is excessive, exceeding the design limit of the packing, resulting in insufficient local seal-specific pressure.
