Specification
A QVF fluid flow teaching
system module designed to study the operation of valves and flow meters
and the pressure loss characteristics of pipeline fittings. Incorporating
a PVC rough bore pipe and smooth bore pipe, 900 bend, 900 tee, gradual
expansion, sudden contraction, 1800 bend, globe valve, ball valve, control
valve, diaphragm valve, venturi meter, orifice meter and a variable
area flow meter, all manufactured in borosilicate glass. Supplied with
a pressure transducer and indicator, interconnecting pipework and supporting
structure. Complete with an installation and maintenance manual and
tool kit.
Experimental Capabilities
- Pressure loss through
pipeline and fittings
- Pressure loss/flow rate
relationship, through different valve designs
- Determination of valve
constants
- Relationship between pressure
drop and flow through an orifice meter, venturi meter and variable
area flowmeter
- The operation of valves
and flow meters
Water is used in all experiments.
Other fluids may be used to investigate pressure drop characteristics
over wide range of Reynolds numbers.
The experiments are also
designed to provide training in chemical process equipment operation.
Optional Manuals
The equipment can be supplied
with the following manuals:
Tutor's manual: The
basis of a lecture course on valve design, flow measurement and friction
in pipeline systems. Also including operating instructions, experiments,
typical results and answers to student questions.
Student manuals provide
the basics of valve design, flow measurement and friction in pipeline
systems and practice with plant operating instructions.
Experiment booklets
provide step-by-step instructions for performing the experiments, data
to be recorded and questions to be answered.
Additional copies of the
student manuals and experiment booklets can be reordered.
Description
The equipment consists of
three test circuits fixed to a free-standing, plastic coated backboard
housing the pressure tapping selection valves, digital pressure indicator,
pressure transducer and variable area flowmeter. The fluid flowrate
through each circuit is controlled by a flow control valve and measured
by the variable area flowmeter.
Each circuit can be tested
individually by means of isolation valves. The pressure at each point
in the circuit is given by the digital pressure meter and simply selected
by means of multiport selection valves.
The equipment is designed
for direct connection to the main water supply or an optional recirculation
pump can be supplied.
Circuit one contains a length
of smooth and rough bore pipe and various pipeline fittings to allow
determination of pressure loss at various flowrates.
Circuit two contains four
valves and allows the pressure loss, operating characteristics and the
valve constant for each valve design to be determined.
Circuit three contains a
venturi meter and orifice meter and, together with the variable area
flow area, allows the relationship between pressure loss and flow to
be investigated.
Note
This unit is supplied pre-assembled.
A mimic diagram, fixed to the backboard, ensures simple identification
of components.
Options
Either steam or electric
heating.
