Description
Technical field
The present invention relates to a kind of steam point vapour device, more particularly, to a kind of energy-saving facile type steam point vapour device.
Background technology
The operation of current many equipment needs to use steam, and general factory is all that the steam of main pipe rail is passed through into gas-distributing cylinder
Distinct device is respectively supplied to after dividing vapour.And the steam pressure that different equipment needs is different, therefore, typically on steam pipework
Pressure-reducing valve is set to be supplied again after being depressurized.
Pressure 8-10bar, pressure 4.5-6bar after decompression before general steam pressure-reducing；Use vapour load：Winter average 20T/H,
Summer average 6T/H, therefore summer steam consumption is fewer than winter a lot.Existing system does Stress control using big valve, according to the above
Parameter, when in the winter time big valve can just realize control require.But be due to Load in Summer it is small, it is necessary to quantity of steam it is smaller,
Therefore big valve is needed to be maintained at small guide vane for a long time, this mode of operation has following drawback：On the one hand to big Valve controlling essence
Degree has certain influence, because the sealed regulating valve of level Four is to allow the presence of certain leakage rate, certainly will be steamed if valve selection is big
Vapour leakage rate is just big；And valve is big in itself, thermal loss caused by radiating is also more.On the other hand due to the frequent pneumatic frequent tune of meeting
Section, therefore the service life and precision of valve can be influenceed, certain waste is also resulted in addition；Therefore need to enter current configuration
Row adjustment.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of structure setting is simple
Energy-saving facile type steam point vapour device.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of energy-saving facile type steam point vapour device, including vapour source, steam input pipe, gas-distributing cylinder and steam output pipe
Road, described steam input pipe one end is connected with vapour source, and the other end is connected with steam pressure-reducing pipeline, steam pressure-reducing pipeline with
Gas-distributing cylinder is connected, and described steam output circuit is connected with gas-distributing cylinder, described steam input pipe and meanwhile with 4 steam pressure-reducings
Major diameter pneumatic pressure-release valve is provided with pipeline and a steam by-pass pipeline connection, two of which steam pressure-reducing pipeline, in addition
Minor diameter pneumatic pressure-release valve is provided with two steam pressure-reducing pipelines.
Relief line stop valve is equipped with every steam pressure-reducing pipeline.
By steam flow, described relief line stop valve is arranged on major diameter pneumatic pressure-release valve or minor diameter Pneumatic decompression
In front of valve.
Described steam by-pass pipeline is provided with bypass line stop valve.
Described major diameter pneumatic pressure-release valve is connected pneumatic pressure-release valve source of the gas with minor diameter pneumatic pressure-release valve by pipeline.
Described major diameter pneumatic pressure-release valve is DN250 pneumatic pressure-release valve.
Described minor diameter pneumatic pressure-release valve is DN100 pneumatic pressure-release valve.
Described steam pressure-reducing pipeline is parallel-connection structure with steam by-pass pipeline.
By setting a plurality of steam pressure-reducing pipeline, and the Pneumatic decompression of different size is set on steam pressure-reducing pipeline
Valve, can be according to the situation of the different steam consumption of Various Seasonal, from opening corresponding pneumatic pressure-release valve.When Load in Summer is small
Wait, from the steam pressure-reducing pipeline where two minor diameter pneumatic pressure-release valves of unlatching, and by other steam pressure-reducing pipelines and steam
Siphunculus road is turned off；When winter load is big, one of major diameter pneumatic pressure-release valve and a minor diameter pneumatic pressure-release valve
The steam pressure-reducing pipeline at place is opened, and other steam pressure-reducing pipelines are turned off with steam by-pass pipeline, now, separately there is one group big
Steam pressure-reducing pipeline where diameter pneumatic pressure-release valve is as standby.
Compared with prior art, the present invention has advantages below and beneficial effect：
First, it is provided with 4 steam pressure-reducing pipelines, and the Pneumatic decompression of different size is set on steam pressure-reducing pipeline
Valve, can be according to the situation of the different steam consumption of Various Seasonal, from opening corresponding pneumatic pressure-release valve.It can avoid subtracting because pneumatic
Control is unstable caused by pressure valve type selecting is excessive, increases the possibility of " vibration ", especially in load small summer；
The 2nd, the pressure-reducing valve of different-diameter is set, and minor diameter pneumatic pressure-release valve can also reduce leakage rate and the radiating of steam
Loss, plays a part of energy-conservation.
3rd, compared to the aperture size of adjustment major diameter pneumatic pressure-release valve, operated using minor diameter pneumatic pressure-release valve is convenient,
Improve control convenience.
