ADR aluminum manhole cover for tank trailer

Introduction:

ADR manhole cover (manlid) is installed on the top of tank trailer to prevent the inside fuel from leakage when tank tanker is over rolled,with PV vent valve inside to adjust the pressure.When there is pressure differences inside and outside the tanker,it will automatically inlet or exhaust air to adjust the pressure so that it can ensure the safety and environmental protection.It is suitable to transport petroleum,diesel etc.

 

Specification:

1.Material:aluminum alloy 

2.Max emergency flow rate: 7000m³/h(when 34KPa)

3.Emergency Open Pressure: 21Kpa-32Kpa

4.Working Temperature:-20~+70ºC
5.Install Method: Flange

Functions:

1.Emergency Exhausting Device:

When the tanker truck in the high temperature condition,manlid will automatically exhaust the air inside to release the pressure,ensuring the safety of the tanker.

2.Secondary Open:

when open the upper blinder plate,it will release the pressure out to prevent the operator against dangerous Kick-Back that can experience due to build up of residual pressure.

3.With PV vent:

with the functions of anti-flow when the tanker is over rolled and high sensitivity  to inlet or exhaust air. Positive pressure: +6~+8KPa   Negative pressure: -2~-3KPa

4.With the key: to lock the manhole for fuel tanker safe.
