Moisture discharged by humidity discharging pipe, because floating ball device prevents ponding from humidity discharging pipe pours in down a chimney heat-insulation layer.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
Below in conjunction with the accompanying drawings, further explaination is of the invention.
As shown in figure 1, instrumentation tubes 2 are direct-burried steam instrumentation tubes, it is heat-insulation layer between outer tube 1 and instrumentation tubes 2.General work
Make to be high-temperature steam in pipe 1, temperature can reach 100-250 degrees Celsius, and instrumentation tubes 2 are connected with the height in water collector 21, instrumentation tubes 2
Warm steam can produce condensate, and the temperature of condensate is generally 70-80 degrees Celsius.The cooling water tank 13 of the present invention is typically embedded in cellar for storing things
In well, the cooling water tank 13 is divided into upper water box 9 and lower header by a dividing plate 16, is used to install relevant device above, dividing plate 16
Lower section is provided with a baffle plate 14, and the bottom of the baffle plate 14 and cooling water tank is not attached to, and so, lower header will be divided into two and communicate
Two parts.During work, the bottom memory of water tank has the normal-temperature water of certain altitude.A draining is provided with the side of cooling water tank 13
Pipe 11, the outlet of drainpipe 11 is connected in sump.When the water in cooling water tank 13 gradually increases, water level exceedes drainpipe 11
Water inlet when, will be automatically drained out.
Water collector 21 is connected with a drain pipe 3, and the other end of the drain pipe 3 is by the top of cooling water tank 13, from dividing plate
16 enter the left side of cooling water tank.Drain pipe 3 is located at that section on cooling water tank top provided with a work gate valve 51 and starts gate valve
52, both concatenate is generally normally open with the gate valve 51 that in drain pipe 3, works, and starts switch of the gate valve 52 when equipment debugging.
Closed when equipment is installed during not enabled, to ensure the safety of equipment debugging.After equipment debugging is good, operating valve is normally opened, starts lock
Valve 52 is closed.One section of drain pipe is parallel with gate valve 52 is started, this section of drain pipe series connection one aids in gate valve 53 and sensing gate valve
54.After equipment is started shipment, auxiliary gate valve 53 is normally opened, and sensing gate valve 54 is temperature sense or pressure sensitive.After condensation flow, sensing
Gate valve 54 completes switching function at temperature or Stress control.During work, the condensed water in direct-burried instrumentation tubes can be gathered in product
In hydrophone, because the steam pressure in direct-burried instrumentation tubes is than larger, condensed water can be pressed into the water level in cooling water tank higher than row
It will be discharged during the inlet port of water pipe.The condensed water of high temperature becomes normal temperature after the normal-temperature water cooling water of cooling water tank simultaneously
Water, thus will not emit steam in discharge.
Heat-insulation layer can produce moisture at work, if do not discharged, heat-insulation layer can gradually fragmentation, largely effect on heat-insulation layer
Heat insulation effect.Sleeve 4 is cased with the outside of drain pipe 3, space is left between the sleeve pipe 4 and drain pipe 3, forming one can
To pass through the pipeline of water.In the porch of the pipeline and direct-burried instrumentation tubes 2 and the heat-insulation layer of outer tube 1.The pipeline is in cooling water
The humidity discharging pipes of case Duan Houyu mono- are connected, and the other end of humidity discharging pipe 7 is placed in above cooling water tank, and set in outlet an elbow.The humidity discharging
Pipe 7 is provided with a gate valve and ball-cock assembly, and the ball float of ball-cock assembly sets the water with the normal-temperature water of the bottom of cooling water tank by a connecting rod
The appropriate location in face.Passed through in the connecting rod and a soft seal cover 10 is provided with baffle plate 13.Whole humidity discharging process is, when in humidity discharging pipe
Moisture（Vapor）Gradually increase, pressure gradually increases, reach after certain value, ball-cock assembly is opened, moisture discharge.As moisture row
After going out, pressure reduction, ball float rises, and ball-cock assembly is closed.If encounter cooling water tank ponding, ball-cock assembly rises, and ball-cock assembly is closed
Close, it is to avoid ponding pours in down a chimney into heat-insulation layer.
A balance pipe 8 is also set up in cooling water tank, the balance pipe one end is placed in above the water surface of cooling water tank, the other end
It is placed in outside cooling water tank, and keeps outlet less than the outlet of humidity discharging pipe.When whole equipment works, the steam pressure in drain pipe
The pressure of the water of cooling water tank can be higher than, can so be ensured, the steam water of drain pipe will not pour in down a chimney.It is whole if meeting flood
Individual to store into meeting by water submerged, the pressure of the water of cooler bin can become big.The balance pipe is exactly to keep the water in condensation water tank to exist
Normal pressure is kept in ponding, the pressure of steam in drain pipe is not above.
An observation panel is additionally provided with above cooling water tank, observation panel is provided with a removable cover 6.The observation panel is used to usually examine
Used when repairing.
