Ultimate Guide to Anti-siphon Countercurrent Vacuum Leakage Test Machine

1. What is an Anti-siphon Countercurrent Vacuum Leakage Test Machine?

The Anti-siphon Countercurrent Vacuum Leakage Test Machine is engineered to simulate negative pressure intrusion, backflow resistance, and anti-siphon performance of intelligent toilets and their accessories.

• Anti-siphon: Prevents siphonage or backflow of contaminated water into the sanitary supply line.
• Countercurrent vacuum: Creates a controlled negative pressure to simulate backflow and detect leakage.
• Applications: Testing smart toilet sitting devices and related components under vacuum and negative pressure conditions.

2. Relevant Standards and Typical Test Methods

Compliance with international standards is critical. The following standards are commonly associated with the Anti-siphon Countercurrent Vacuum Leakage Test Machine:

• JC/T 285-2010: Stool Cleaner – clauses on counter-current and negative pressure performance.
• CBMF 15-2016: Intelligent Toilet – anti-siphon and backflow resistance standards.
• GB 26730-2011: Gravity Flush Device for Sanitary Ware – section on anti-siphon function.

Typical Test Methods:

• Generate negative pressure from 0 – 100 kPa to simulate backflow conditions.
• Anti-siphon test station to ensure resistance to siphonage.
• Leakage test station to identify unintended fluid ingress or egress under vacuum.
