1. What is an umbrella valve?
The structure of the umbrella valve is an umbrella shape, and the end is enlarged beyond the outer circle of the installation hole. After installation, the positioning purpose is achieved. At the same time, the cylindrical section of the valve diaphragm and the installation hole are designed for interference assembly. The umbrella valve is made of silicone or rubber. After the valve diaphragm is assembled to the accessory, the buckle column end close to the umbrella shape can be directly fixed.
Silicone umbrella valve
The silicone umbrella valve is characterized by its unique umbrella structure. This valve can automatically open when subjected to a certain pressure, and automatically close after the pressure is released, which plays a good role in pressure regulation. Silicone umbrella valves play an important role in respiratory equipment, fluid control systems and other fields, bringing great convenience to people’s lives.
2. What is the function of the umbrella valve?
The umbrella valve is designed to solve the installation troubles of the one-way valve diaphragm (the one-way valve diaphragm with a sealing function and a flat structure) and the poor reliability and air tightness. The umbrella cap of the umbrella diaphragm is compressed to deform and shrink the umbrella mouth of the umbrella diaphragm, and the edge of the umbrella mouth fits the end face of the valve body. The contact area between the umbrella mouth and the one-way valve increases, and the umbrella mouth tightly covers the exhaust holes around the installation hole, which can improve reliability and air tightness. Air tightness is generally used in medical accessories, and water tightness is generally used in drinking water and food-grade liquid equipment. The pressure value of the umbrella surface can be tested according to the glue position and depth.
The lightweight umbrella anti-reverse valve allows the fluid to flow in one direction and prevents the fluid from flowing back in the opposite direction. b. This valve is automatically operated, easy to install, and suitable for any installation direction. (Even if it is installed upside down, it will not affect its work)
3. What are the optional materials for umbrella valves?
Umbrella valves are made of rubber, and the materials available are Silicone/VMQ, Viton/FKM, Fluorosilicone/FVMQ, NBR, EPDM, etc. Different materials have different functions according to different application scenarios. So when customers buy products, we must understand the actual application environment of the product and choose different materials.
4. How are umbrella valves classified according to their application areas?
As a high-precision, high-reliability control valve, silicone umbrella valves can be widely used in many fields such as automation control and fluid control. Whether it is to prevent liquid overflow, simplify the drinking process, or control flow, silicone umbrella valves can play their unique advantages.
