WO/2016/175644 SEALING SHIELD FOR PROTECTING GAS METERS||WO||03.11.2016|
||PCT/MD2015/000003||CERBARI, Serghei||CERBARI, Serghei|
The invention relates to the industrial use of a sealing shield on gas meters, which can be used: in the private sector by installation companies in order to improve and ensure the protection of gas meters, and also more broadly in the context of public services for the installation of sealing shields on existing or newly installed meters. The invention consists of a sealing shield and locking elements in the form of semi-circular catches with a locking system, which completely enclose and protect a gas meter, locking the joint by sealing, and protecting against external unauthorized intervention. As a result of the design of the invention consisting of two separate component parts, the sealing shield can be mounted independently of the meter without the need to dismantle the latter, since the sealing shield is mounted directly on the meter, thereby protecting both the point of entry of the gas pipes (flanges) and existing seals.
