Description
Technical field
This utility model belongs to pressure regulator valve technical group field, relates to combination type weakening noise reduction pressure regulator valve group.
Background technology
Being cardinal task in iron and steel enterprise's environmental protection, the main target of improvement is flue gas, airborne dust and noise,
This three is referred to as the three disasters.Flue gas and airborne dust are under modern technologies effect and under the promotion of market access condition
All achieving good effect, the evil of noise is the most fundamentally governed only, powerful strange
The sound has broken the normal order of work of work on the spot person, is the old problem of iron-smelter headache, the most thorny
The most helpless.The source of this noise is exactly the pressure regulator valve group of blast furnace gaspipe network end.
Between Zao Nian, the blast furnace volume of China is little, and great majority are low pressure atmospheric operations, pressure regulator valve group
Effect be not the most prominent, vibration and noise is the most usual.In the last few years, strengthening smelting carried out by blast furnace,
High pathogenic wind-warm, high blast increase furnace top pressure.Do comprehensive utilization the most in the recent period, do not waste the energy,
UTILIZATION OF VESIDUAL HEAT IN, TRT differential pressure power generation is widely used, and original pressure regulator valve group can not meet and changes use
The requirement of situation, creates altofrequency vibration and is intended to deaf shriek with ear-piercing.For solving the problem existed,
A lot of iron-smelters have carried out the improvement of planform with equipment manufacturing to traditional valve group, even have individual
Other enterprise spends high price to order external product, but its result produces little effect.Our company is also together with several refinings
Several preproduction has been done in ironworks, is analysed scientifically traditional product during being rebuffed, tradition
The structure of pressure regulator valve group is as shown in Figure 1:
Two ends are respectively arranged with a macroporous plate, and centre is provided with several (3～4) arm, macroporous plate and coal gas
Supervisor's Flange joint, arm determines latus rectum by coal gas inflow-rate of water turbine and pressure regulation ratio, the middle part peace of arm
Dress butterfly regulation valve, regulation valve is set the aperture being automatically adjusted butterfly plate by furnace top pressure, and butterfly plate aperture is more
Little, furnace top pressure is the highest, and furnace top pressure changes with butterfly plate aperture, it is achieved regulatory function.This butterfly plate
As the functional part of regulation flow in the regulation environment that valve is low at pressure, pressure reduction is little, flow velocity is low of shape
No problem, but high pressure, High Pressure Difference, high flow rate situation under, it may occur that following feelings
Condition: 1. valve plate and valve rod are conjoined structure, in suspended state between opening and closing, rushing at air-flow
Can vibrate under hitting；2. valve is in closedown, opening process, and butterfly valve is arc-shaped motion, air-flow
Eddy current can be produced；3. regulation valve is not total enclosing valve, and standard specifies permission 5～the leakage rate of 10%,
This leakage-gap can make medium cross stream the birdie screamed accompanied, and pressure is the biggest, and flow velocity is the fastest, makes an uproar
Sound is the biggest.It is therefore seen that the vibration of pressure regulator valve group and noise the most thus produce.
The defect of the tradition congenital existence of pressure regulator valve group, it is impossible to meet the working condition changing state of arts,
Today that particularly environmental protection is above all, industry colleague and device fabrication producer start to improve, transform this
Individual equipment, has mainly done such work:
A () replaces down regulation valve, use airtight eccentric-butterfly-valve instead:
This change is to turn round and look at name not have pragmatic, and airtight leakage of eccentric-butterfly-valve is conditional on, and it needs
Constant temperature and pressure friction, this is because this butterfly valve is linear sealing, sealing surface is the least, meets vibration close
Front cover can be subjected to displacement, and will leak after displacement.It addition, all metal materials are fine in the operation of rolling
Dimension shape is different, and horizontal and vertical difference is very big, and its contraction percentage of area difference is very big, and
Expand and shrinkage ratio is the most different, will change if not constant temperature and pressure, so, national standard
This valve of clear stipulaties can not be as reliable shearing device, it is necessary to configuration blind plate or blank-plate valve.
B the decompression of () dilatation reducing is slowed down:
It is feasible on this theoretical method, is the most but impracticable, a seat height stove one hour ten
Several～hundreds of thousands m3Coal gas, in pressure regulator valve group dilatation, only reaching what decompression was slowed down, its amount is the least,
Not interfering with entirety, such as river sea-scatter salt in the same direction, water will not be spoiled.
In sum, existing pressure regulator valve group cannot effectively reduce vibration, reduce noise, it is impossible to very well
Ground meets use demand.
