Enhance heating pipe and be equipped with multiple pressure regulator valves, heating mantle is arranged on pressure regulator valve, the heated set temperature after heating of gas is kept
In T2DEG C, heater wire is arranged on heater wire heating pipe, the heated line temperature after heating of gas is maintained at T3DEG C, T1Less than T2,
T2Greater than T3, T3Greater than T1, gas passes sequentially through warm-up block, regulating valve, heater wire heated transportation.In order to guarantee that gas conveys
Efficiency, the scheme that this programme can be conveyed simultaneously using a plurality of pipeline, as shown in Figure 1, i.e. preferably segmented formula heat gas conveying
System includes two gas transfer pipelines, and the end of above-mentioned two gas transfer pipelines is connected to gas delivery main road, gas
Delivery main road is equipped with pneumatic filter, and heat gas is exported through pneumatic filter.Above scheme is used in air shooter
The mode of road subsection setup heating source improves heating power at the position for needing to reinforce heating, improves gas temperature, avoid
Gas delivery problem caused by low temperature.
As shown in Figure 2,3, the warm-up block of this programme includes module housing, is equipped with spiral pipe, spiral shell in module housing
It revolves shape insides of pipes and is equipped with electric heating circuit, electric heating loop heating flows through the gas of spiral pipe.In order to realize conveying control
It makes, is successively arranged pressure transmitter, gas along gas conveying direction on the preliminary preheating pipe of the upstream of the warm-up block of this programme
Dynamic control valve.
As also shown in e.g. figs. 4-7, the heating mantle internal layer of this programme is equipped with the heater strip that bending extends, and one end of heating mantle is equipped with
Multiple buttons, the other end of heating mantle are equipped with multiple button holes, and button and button hole fastening cooperate, and heating mantle passes through above-mentioned fastening
Cooperation is locked on pressure regulator valve.In order to improve the effect of pipeline pressure regulation, along gas conveying side on the enhancing heating pipe of this programme
To being equipped with pressure regulator valve A, pressure regulator valve B, enhancing heating pipe between pressure regulator valve A and pressure regulator valve B is equipped with pressure gauge, on pressure regulator valve B
It is additionally provided with pressure transmitter.
This programme discloses a kind of segmentally heating system of special gas supply, carries out to entire special gas heating system
Gradation study.First to gas source come out gas carry out unified heating, to the gas flowed through no matter the temperature for Chu Laiing how much,
30 degree, rated power 2400W all are previously heated to, is then entering subsequent equipment distributor box-board, this ensure that
The temperature of gas source is not very low.Secondly, the important pressure regulator valve flowed through to centre has carried out individually after the heating of (preheating) module
Heating.Heating mode originally is single, and the heating power to pressure regulator valve is also every meter of 30W, but actually pressure regulator valve is to need most
The component of heat compensation is heated and carried out, so this programme has individually carried out independent heating design to pressure regulator valve, devises one
Heating jacket (heating mantle) of a shape as pressure regulator valve, directly individually covers on pressure regulator valve, at the same heating power also from
30 W before greatly improve 600W till now, sufficiently meet the demand for heat of pressure regulator valve, while heating temperature is set as 37
Degree is set slightly higher than the temperature of front.Disk heating and pipeline heating, this programme after pressure regulator valve still use
Heater wire heating mode originally, temperature are set in 35 degree, every meter of 30W of power.In this way, the heating system of entire special gas supply
System, segmentally heating temperature is 30 degree, 37 degree, 35 degree respectively, and heating power is 2400W, 600W, 30w/m respectively.Such point
Section heating mode effectively avoids the heating " blind spot " in entire heating system, solves the difficulty in gas conveying, whole
A gas supply system becomes very unimpeded, effective, and flow is also sufficiently ensured.Gas first passes around heating by pipeline
Block (warm-up block) is tentatively heated, and is carried out pressure regulator valve local heating using pressure regulator valve, is protected pressure regulator valve, increases pressure regulator valve
Service life is finally heated by disk entirety heater wire, again to guarantee the temperature and flow velocity of gas.Meanwhile this programme
Heater wire can be divided into left and right disk, once single disk heat damage, another disk is unaffected can still to work.Heat small jacket
(heating mantle) heats main valve member, carries out local heating to main valve member, guarantees in this way when gas is by these valve members, gas
It can sufficiently be heated, it is also ensured that this part valve member will not cause to drip because of heating temperature unevenness and ice condition goes out
It is existing, valve is preferably protected, valve service life is increased.This programme uses the preliminary heat gas of heat block, enters master in gas
Heat block heating is first passed through before wanting pipeline, makes gas that there is certain temperature, can make subsequent heating more uniform in this way, it can also
To play the role of tentatively protecting the pipeline and valve member in disk below.This programme controls multiple heating modes using multilist,
It is controlled using multiple temp controlled meters, heating module is segmented, so that better heat gas, is that gas obtains sufficiently
Production equipment is entered back into after heating.
Existing scheme heating mode is heated pipeline and valve member by canoe using heater wire, and is led to outside
It crosses heat-preservation cotton package and carries out Heat preservation.This programme carries out Heat preservation by heater wire heat-preservation cotton in prior art basis
Outside, it increases HEATING BLOCK (heating module) and heats small jacket for pressure regulator valve customization and carry out segmentally heating, to make
Gas flowing is more stable, the icing phenomenon that drips caused by flow velocity is too fast is prevented, to increase using equipment life.This programme changes
Existing heating mode is become, has realized heating section, different heating temperatures is set, different heating powers, Lai Shixian are designed
Special gas supply is convenient, unimpeded.Based on the above feature, the Segmented heating gas delivery system of this programme compares existing scheme
With substantive distinguishing features outstanding and significant progress.
This programme Segmented heating gas delivery system is not limited to content disclosed in specific embodiment, in embodiment
The technical solution of appearance can the understanding based on those skilled in the art and extend, those skilled in the art combine according to this programme
The simple replacement scheme that common knowledge is made also belongs to the range of this programme.
