The
invention
- The
problem to be solved:
High quality can be produced and in the
same time production cost reduced,
significantly comparing to the
traditional technology.
|
- Definition:
The flanged gate valve is
designed to be mounted between flanges.
The gate is mountable into the
single-piece cast housing through the
flow tunnel. The gate body is supported
by bearing, and the lug of the guide rail
is made of the same material as the gate
body
|
- Presentation:
The gate valve housing is made
of a one piece eliminating the bonnet.
The gate is mounted into the housing
through the tunnel. The tunnel is widened
in the direction of the valve mounting to
facilitate the guide lug approach. After
mounting the gate through the tunnel the
guide bearing of the gate can be mounted
in the fully open state of the valve. The
bearing is secured by sealed bolts. The
cast gate body is rubber coated. The
sealing surface of the gate is horseshoe
shaped on the top and sides. On the
bottom a large diameter cylindrical
surface is formed joint by radius to the
sealing surface on the sides. The bottom
part of the sealing surface wraps around
the spindle cavity. The gate body is
effectively open from the bottom so that
to avoid blocking of the movement of the
spindle.
The economical design of this gate valve,
as compared to the conventional gate
valve design, results in substantial
weight reduction. The size reduction
facilitates the mounting of this valve
between the flanges similarly to the
blade type gate valve. For the mounting
bolts, holes located on the upper and
center part of the flanges are threaded
blind holes, the rests are through holes.

- Advantages:
-No centre beading, consequently its
machining, sealing and securing are
saved.
-The valve guide is made of the same
material
-The slide way eliminates fretting
corrosion
-Single-piece cast housing has increased
rigidity
|
- Stage
of development: Operation is
introduced by an prototype, model is can be seen.
|
- Documentation
available: Yes,
partially available.

The
inventor(s)
- Self
introduction:
I had worked for a industrial valve
manufacturer factory as a designer,
responsible for the development of valves
for pipelines.
Since I have been retired I started to
use AUTOCAD system, and I work on the
developing of valves according to my
conception.
