Brief description of the drawings
Figure one is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings, utility model of the present invention is further explained.
As shown in figure, instrumentation tubes 2 are direct-burried steam instrumentation tubes, are heat-insulation layer between outer tube 1 and instrumentation tubes 2.Typically
It is high-temperature steam in instrumentation tubes 1, temperature can reach 100-250 degrees Celsius, and instrumentation tubes 2 are connected with water collector 21, in instrumentation tubes 2
High-temperature 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
Store 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, dividing plate 16 above
Lower section be provided with a baffle plate 14, the bottom of the baffle plate 14 and cooling water tank is not attached to, and so, lower header will be divided into two phases
Logical two parts.During work, the bottom memory of water tank has the normal-temperature water of certain altitude.A row is provided with the side of cooling water tank 13
Water pipe 11, the outlet of drainpipe 11 are connected in sump.When the water in cooling water tank 13 gradually increases, water level exceedes drainpipe
During 11 water inlet, it 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.That section that drain pipe 3 is located at cooling water tank top is provided with a work gate valve 51 and starts gate valve
52, both are concatenated with drain pipe 3, work gate valve 51 generally normally open, starting 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, this section of auxiliary gate valve 53 of drain pipe series connection one and sensing gate valve are parallel with gate valve 52 is started
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 bigger, 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 it will not emit steam in discharge.
Heat-insulation layer can produce moisture at work, if do not discharged, heat-insulation layer can gradual 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
