Product Description
Introduction :
A check valve,is a mechanical device, a valve,
which normally allows fluid (liquid or gas) to flow through it in
only one direction.
Check valves are two-port valves, meaning they have two openings in
the body, one for fluid to enter and the other for fluid to leave.
There are various types of check valves used in a wide variety of
applications. Check valves are often part of common household
items. Although they are available in a wide range of sizes and
costs, check valves generally are very small, simple, and/or
inexpensive. Check valves work automatically and most are not
controlled by a person or any external control; accordingly, most
do not have any valve handle or stem. The bodies (external shells)
of most check valves are made of plastic or metal.
An important concept in check valves is
the cracking pressure which is the minimum upstream pressure at
which the valve will operate. Typically the check valve is designed
for and can therefore be specified for a specific cracking
pressure.
Heart valves are essentially inlet and outlet check valves for the
heart ventricles, since the ventricles act as a pump.
Features:
1. Small in size, light in weight, compact in structure, easy in
maintenance.
2. Two torsion springs are used excreting on each of the pair valve
plates. Which close the plates quickly and automatically.
3. The quick-close action prevents the medium from flowing back and
eliminates water-hammer effect.
4. This valve is short in length, so that it is rigid and easy to
mount.
5. It is easy to install on pipeline which is laid horizontally or
vertically.
6. This valve is tightly sealed without leakage under the pressure
water test.
7. Safe and reliable in operation, high
interference-resistance.
8. The connection dimensions of flanges accord with the standards
of GB******4 GB***6.*4
9. The face to face dimensions are in accordance with
GB*******9.ISO******2. The stem of the valve should be
perpendicular to the horizontal level when the valve is mounted on
horizontal pipeline. For vertical installation the direction of
flow should be downward
