I have two networks and for each one I use a PC. These network should remain separate because one is an internal network that must be protected and another is the Internet. How can I access these networks with only one PC and to be sure that my intranet is fully protected from the Internet threats ?

2One PC connected to a secure and an unsecured network is a huge security risk.– Ron Maupin ♦Commented Oct 19, 2016 at 1:10

I assume you want to access both networks directly at the same time.
In a professional environment you would use VLANS, which gives you the ability to access multiple networks directly from a single network card and thus system.
The cheap/SOHO option would be to use two network cards.
In both cases you would place very strict rules on the configuration of said system:
1) No routing/(P)NATing/VPN/tunnels or other funny stuff
2) A correctly configured firewall
3) An up to date OS with a strict updating policy
accessing your 2 networks with only one PC it ok, but if you want to fully Protect your intranet, I suggest to use a KVM, this will give you the impression of using a single monitor.
