Silicone Umbrella Valve,High Quality Silicone Rubber Umbrella Valve Manufacturer
 

Product Introduction

 

Umbrella valves are also widely used, which can be used for fluid control functions in a variety of fluid medical equipment, household appliances, automobiles and toys, such as one-way check valves for (disposable) breathing masks, also used in automotive fuel tanks Container exhaust valve, piston pump and diaphragm valve.

 

Umbrella valve is a kind of elastic valve assembly. If you like, you can use diaphragm seal disk or umbrella. These elastomer parts are used as sealing elements in backflow prevention devices such as check valves, exhaust or pressure relief valves and metering valves. When installed in a valve seat, the convex diaphragm will flatten against the valve seat and absorb a certain amount of valve seat unevenness and generate a certain sealing force.

Product Pictures

 

Once sufficient pressure is generated by the head pressure to lift the convex diaphragm from the valve seat, the umbrella valve will allow forward flow, so it will allow the flow at a predetermined pressure in one way and immediately prevent it in the opposite way Reflux.

 

Compared with other types of valves (such as spring-loaded disc valves), the main advantage is that the umbrella valve uses its elastic material properties and preloaded convex shape to form a sealing force on the valve seat, and it uses a central stem Keep at avoiding additional components such as springs, and avoid using one or more central or circumferential disc positioners. This simplifies the design of the components, makes the valve suitable for the smallest application space, reduces the number of parts in the valve, simplifies assembly, and is very cost-effective.

Installation

 

1) Pull-in

These are the most common and are perfect for hand assembly. To install a long tail through the center hole of the valve seat, pull it out, and then pop the valve into place

2) Push-in

These types are preferred when it is difficult to place a long tail in the center hole. For example, deep inside the bottom of a cylinder. Or when the upstream side of the valve is not accessible. For example, when placing the valve on a tank wall that cannot reach the inside of the tank. This type can also be used for automatic assembly.

3) Belleville type

The name speaks for itself, and the shape of the membrane looks like a Belleville spring washer, fixed by an elastic hinge in the middle. That's it! Usually, once a predetermined pressure is reached, the valve will suddenly open suddenly. This is very different from an umbrella valve with an inverted stem, which is more restrictive.

The central valve stem is located downstream of the valve and is held in place by a retainer. The holder may be a separate part or an integral part of the device, wherein the holder is integrated therein, such as a cap or cover above the umbrella valve. This valve seat has only one flow hole and is therefore easier to manufacture.

Check valves are used to control the direction of fluid flow. Designs can include umbrella valves, duckbill valves, Belleville valves and diaphragm valves.

One-way valves can be designed to provide customers with the head loss and flow rate required for a particular application.

A variety of materials and designs are available to handle different fluids and conditions of use.

Silicone duckbill valve is mainly used in patient valve of manual resuscitator.
