How does a One Way Valve control the one way flow of liquid?

A one way valve is a type of valve that allows liquid to flow freely in one direction while preventing liquid from flowing in the opposite direction. The working principle of a only way valve is based on the mechanism of opening or closing the valve core or disc under liquid pressure.

When the liquid flows in the normal direction of the single way valve, the pressure of the liquid will cause the valve core or valve disc to open, allowing the liquid to freely pass through the valve. However, when the liquid attempts to flow in the opposite direction, the pressure of the liquid will cause the valve core or disc to close, preventing the liquid from passing through the valve.

Therefore, a one way valve can ensure that the liquid can only flow in one direction and will not flow in the opposite direction. This design makes single way valves very useful in many applications, such as preventing liquid backflow or preventing liquid backflow in the system.

Where are one way valves used?

Plastic one way valves are commonly used in liquid or gas flow control systems, such as:

1. Drinking water system: used to prevent water backflow or pollution of the water source.

2. Chemical industry: used to control the flow direction of chemicals or other liquids.

3. Agricultural irrigation system: used to control the flow direction of irrigation water.

4. Sewage treatment system: used to prevent sewage backflow or pollution of water sources.

5. Medical equipment: used to control the direction of gas or liquid flow, such as ventilators, infusion sets, etc.

Parameter Specification

What are the specific cases of the application of plastic one way valves in the packaging field?

In the field of packaging, the application cases of plastic one way valves include food packaging, drug packaging, and cosmetic packaging.

In terms of food packaging, plastic one way valves are used to package advanced aquatic products such as whitewater fish, abalone, and sea cucumber. This One Way Check Valve can discharge the air inside the bag, extending the shelf life of the food maintain the fresh taste of the food.

In the field of pharmaceutical packaging, the application cases of plastic bag one way valves include packaging to prevent moisture and oxidation from affecting drugs.

This one way valve can keep the inside of the medicine dry, effectively preventing packaging damage during transportation and storage.

In the field of cosmetic packaging, the application cases of plastic one way valves include packaging with moisturizing effects. This Mini Check Valve can help maintain the original quality and freshness of the product, prevent drying and oxidation, and prevent the invasion of bacteria, mold, and other pollutants.

Can a one way valve reduce pressure?

The main function of a one way valve is to control the one-way flow of fluid and prevent reverse flow of fluid. However, when the opening of the one way valve is insufficient, and the pressure of the fluid in the pipeline exceeds the pressure value of the one way valve opening, the one way Hydraulic Check Valve can play a certain pressure reducing role. This is mainly because the limitation of the opening size of the one way valve can create a resistance. When the fluid in the pipeline passes through the one way valve, it will reduce a certain pressure due to the resistance, thereby playing a role in reducing pressure.
