Medical Silicone Umbrella Exhalation Air Valve Seals

The structure of the (liquid) silicone umbrella air valve is in the shape of an umbrella, and the end is larger than the mounting hole, so as to achieve the purpose of positioning after installation. At the same time, the cylinder segment of the valve diaphragm and the mounting hole are designed for interference assembly, and the umbrella check valve is made of silicone or rubber or liquid silicone material.

(LSR) Silicone umbrella air valves are designed to solve one-way valve diaphragm (one-way valve diaphragm seal role, structure belongs to the planar) installed trouble and poor reliability and air tightness and set, umbrella cap compression of diaphragm make umbrella mouth contraction deformation of diaphragm, umbrella edges and body end joint, umbrella mouth contact area increase with one-way valve, umbrella mouth will install the vent cover closely around the hole, you can improve reliability and air tightness. Air tightness is generally used in medical accessories, and water tightness is generally used in drinking water equipment. The pressure value of silicone umbrella surface can be tested according to the glue position and depth.
