Introduction
KAQ41F gas
ball valve is a kind of valve used to cut off, distribute and
change the direction of medium flow in the pipeline. It only
needs to be operated with a rotation of 90 degrees and a small
turning torque to close tightly. It is most suitable as a switch
or a shut-off valve. The ball valve has a compact structure,
reliable sealing performance, simple structure, and easy
maintenance. The sealing surface and the spherical surface are
usually in a closed state, which is not easy to be eroded by the
medium. It is easy to operate and maintain. It is suitable for
natural gas and other media, mainly used to cut off or connect
the pipeline Medium. This product is suitable for major gas
companies and gas distribution stations, city gate stations, gas
distribution stations, gas pressure regulating stations,
long-distance pipelines and urban gas pipeline
networks.

Use
Range of Product
The ball valve produced by
KMO is suitable for the opening and closing devices that control
the connection or cut off of the pipeline medium under various
pressures, temperatures and mediums of medium and small caliber
pipelines; relying on the pressure of the medium to press the
ball on the valve seat at the outlet end, Its use pressure and
diameter are subject to certain restrictions. Adopt 90°
transmission, so the switch is convenient and quick, and can be
quickly opened and closed.
Operation principle and structure
description
1. The
channel of the ball valve is smooth, which is convenient for
cleaning the pipeline and conveying media.
2. The seal adopt PTFE (Teflon) and other materials, with good
lubricity and elasticity, small friction with the sphere, and
long-life.
3. Quick opening and closing, only need to turn the ball 90° when
opening and closing, convenient and rapid.
4. The fluid resistance of the ball valve is low. When fully
opened, the cross-sectional area of the ball aisle, the valve
body aisle and the connecting pipe are equal, and it can be
imagined in a straight line, the medium flows through the ball
valve, which is equivalent to flowing through a straight pipe.
The fluid resistance of the ball valve is the smallest among
various valves.
5. The drive modes that can be configured are manual, worm gear
drive, pneumatic, electric (explosion-proof), which can realize
automatic control remotely and can meet the user's various
working conditions.
Note for
Installation
1. Before installation,
please check carefully whether the valve mark is in accordance
with the requirements for use.
2. Before installation, please check the valve channel and
sealing surface with a clean soft cloth to remove dirt.
3. Before installation, please check whether the manual device is
flexible and free of jamming.
4. When the valve is in the center of the pipeline, please
tighten the diagonal bolts first.
5. It is not allowed to install valves while welding pipeline
flanges or immediately after welding.
6. It is not allowed to use wrenches or other objects as levers
of the transmission device to operate the valve.
7. All bolts on the pipeline should be tightened.
8. The valve in the middle of the pipeline flange should avoid
being squeezed.
9. Keep a space for inspection and maintenance.
10. Under normal working conditions, the valve should be kept
fully open or fully closed. It is forbidden to partially open the
door in order to adjust the fluid flow.
11. Clean the valve frequently to prevent the dust, grease or
residual liquid accumulated on the valve body and valve stem from
wearing and corroding the valve.
Usage and
Maintenance
When the valve is in using,
it should be repaired regularly to check the sealing situation.
If it is aging, invalid or the body is corroded, it should be
repaired or replace in time.
Turn 90° counterclockwise
to open the valve and turn 90° clockwise to close the
valve.
If there are any problems
when the valve is in use, it should be stopped immediately to
find out and fix.
Generally, the ball valve
does not have a heat-insulating function. When the medium is a
high-temperature or low-temperature fluid, a warning sign should
be set up if it will harm to people skin.
The valve surface and valve
stem are easy to stick ash, oil and residual medium, which will
damage the valve, even will be a gas explosion. So the valve
should be cleaned frequently to ensure that it is working
normal.
KMO reminds that it must
make sure that the fittings on the valve body and the downstream
pipeline have been relieved of pressure before , then people can
disassemble and decomposition to repair.
If the components need to
be replaced, the replaced must be consistent with the material
and size of the original parts. Valve O-rings and gaskets can be
ordered as spare parts for repair and maintenance
If the item is disassembled
and reassembled, people should be keep carefully to avoid
damaging to the sealing surface of the components.
The disassembled individual
parts can be cleaned by dipping. Metal parts that have not been
decomposed can be scrubbed with clean detergent silk
cloth.
Non-box parts should be
taken out after cleaned, and should not be soaked for a long
time.
The cleaned parts need to
be assembled in time, and should not be uncovered for a long
time, otherwise it will rust or be contaminated by
dust.
Use grease for lubrication.
Apply a thin layer of grease on the surface of the seal mounting
groove, apply a thin layer of grease on the rubber seal, and
apply a thin layer of grease on the sealing surface and friction
surface of the rod.
Before assembly, keep the
inner cavity clean.
