Steam inlet tube 7：Steam utilization steam heat is introduced to be heated.Heated using steam, can be inflammable
Quick-fried region is used.
U-shaped water-collecting tray：Making the U-shaped water-collecting tray of two pieces altogether with 0.3~0.5mm iron sheets, (the first U-shaped water-collecting tray 9 and second is U-shaped
Water-collecting tray 14), liner heat-preservation cotton layer 11 and waterproof waterproof plastic tarpaulin 17 (as shown in Figure 5 b) of layer, water-collecting tray catchment and play guarantor
Warm layer pad effect, this part need to be processed guarantee according to body size and match with valve body, liner waterproof plastic tarpaulin aspect product
Need to be more roomy than other positions, so can be when poorly sealed, can carry out wrapping to whole valve body prevent steam from leaking, water-collecting tray
Carried out coupling guarantee globality with attachment bolt 16 with heat-insulation layer, condensate is collected back in middle part processing collection water outlet
Receive, above design basis is low-pressure steam (160 DEG C, 0.65MP).Preferably, it can also set and seal in Ji Shuipaifangkouchu
Pad.
Heat-preservation cotton layer 11：(the first U-shaped U type water-collecting trays of water-collecting tray 9 and the 2nd are folded up between the two pieces water-collecting tray of making
14) heat in heating, is prevented to scatter and disappear, it is ensured that the efficiency of heating surface and heating uniformity.
Top bolt 12：Heating unit is positioned on valve body 100, the welded nut and by the spiral shell being screwed on pipeline
Bolt is affiliated in the raised position of valve body, you can limits device is moved axially along pipeline, can also ensure that device is fixed on valve body.
Bottom bolt 13：For fixing heat pipes, swung while limiting heater, it is ensured that device is not sent out
Life is crooked.
Pipe is prepared according to body size and placed on valve, by two blocks of iron sheets for being used to manufacture U-shaped water-collecting tray of lower honest material
In sandwich heat-preservation cotton, perforated with iron wire after colligation on the valve body, U-shaped water-collecting tray height need to be higher than the steam opened in heating tube
Showerhead hole, U-shaped water-collecting tray is wrapped up using waterproof plastic tarpaulin, and waterproof plastic tarpaulin should be greater than U-shaped water-collecting tray, and by by tarpaulin
It is bundled on valve body to fix water-collecting tray while playing sealing function.Check the tightness that water-collecting tray is engaged with valve body, it is ensured that steam
Vapour will not largely leak from there.Steam is passed through from top to heat valve body both sides, steam condensate falls into collection after heating
Collected in water pond through collecting water outlet.
Steam passes through pipeline and both sides connecting tube 5 from the 7 of the steam inlet tube on heating unit top enter heating unit
Gate valve body both sides are delivered to respectively, then are sprayed from the steam jet of the perforate of heating tube gate valve plate guide groove position is added
Heat.Wherein, all pipelines of heating unit are coupled using pipe screw thread, can carry out dismountable.Being coordinated according to body size can
Installation can be adjusted by changing connecting tube, be can adjust heating tube shower nozzle to the distance of valve body using loose joint and threaded fitting, utilized
Internal thread elbow nozzle adjustable can meet valve plate guide groove to valve plate guide groove position using the heating tube shower nozzle for changing different length
Longer gate valve heating.Device regulation can be placed directly on valve after installing and be heated without special stand.Further,
Installing heat-insulation layer additional outside heating unit prevents heat from distributing.It is further to make U-shaped catchment using heat-insulation layer liner iron sheet
Disk, the middle part of water-collecting tray sets floss hole 10 to be collected to condensate.
Made using present apparatus heating valve body both sides guide groove position after tar softening gravity flow, it is ensured that valve plate flexible movements, this dress
Demountable assemble type structural shape is set to, materials are simple, meet various by the combination of replaceable connecting tube different length size
Gas gate valve heating of the specification without muff, therefore the device has wide variety of value.
Combined valve heater structure with heating function provided herein is simple, materials are easy, processes, grasp
Make it is convenient, primarily directed to the heating of the large-scale gate valve without insulation jacket, particularly medium crystallization, the solidification in gas are influenceed
When valve can not be acted, by the direct adjunction to guide groove, soften crystallization and coking, it is ensured that valve is normally-open, for changing
Work enterprise easily fires region and used, with preferable promotional value.
In summary, the application can avoid valve plate because of the medium hardening in pipeline, and valve can not be opened and closed, it is to avoid be opened by force
Damage to valve, reduces steam consumption, improves heating effect.In addition to applying in large-scale gate valve, it can also apply
In in other chemical gases pipelineds, for example, containing easily crystallization, Yi Jijiao in medium, easily firing and itself being without heating and thermal insulation
The online large-scale gate valve of chuck.
Although above by describing the utility model with reference to exemplary embodiment, those skilled in the art should
This understands, in the case where not departing from the spirit and scope that claim is limited, can be to exemplary implementation of the present utility model
Example carries out various modifications and changes.
