Section 1: Self-contained Nitrogen Sealing Valve Imported Product Overview
Germany VordWODEThe imported self-sealing nitrogen valve is primarily used for constant pressure control at the top of storage tanks to protect the materials inside from nitrogenation and ensure tank safety. The nitrogen sealing valve consists of two main parts: a rapid discharge valve (nitrogen discharge valve) and an automatic pressure regulating valve (nitrogen supply valve). The rapid discharge valve is composed of a pressure controller and a single seat cutting valve.
When the pressure inside the storage tank reaches the set pressure, the rapid discharge valve quickly opens to release the excess pressure inside the tank. The low-pressure regulating valve opens the valve to inject nitrogen into the tank when the pressure inside the tank decreases. The low-pressure regulating valve must be used when the pressure is1.0MpaAt pressure, the现场 pressure is high, an automatic pressure regulating valve must be installed to reduce the pressure.1.0MpaThe following is permissible. Pressure can be set in segments, from0.5Kpa Please provide the Chinese content to be translated.66 KpaBelow, medium temperature ≤80℃。
Section II: Imported Self-sealing Nitrogen Shut-off Valve Product Features
(1Operates without external energy, capable of functioning in places without electricity or gas, offering convenience, energy savings, and cost reduction.
(2The nitrogen sealing device provides nitrogen supply, with convenient nitrogen release pressure settings, allowing for continuous operation.
(3The pressure detection diaphragm has a large effective area, with a set spring stiffness that is small, operates sensitively, and ensures a balanced working device.
(4The valve rod features a frictionless design with minimal friction, rapid response, and high control precision.
(5The nitrogen supply unit is operated by a controller, achieving a pressure reduction ratio of100:1Excellent pressure relief and high control accuracy.
(6To ensure the safety of the tank, a breathing valve must be installed on the tank top.
(7The breath valve plays a safety role, avoiding the defect of frequent opening and closing, which is prone to damage in conventional nitrogen sealing devices.
