Background technique
At present, in engineering for hydrophobic, the draining of direct-burried prefabricated thermal insulation steam pipe line, common practices is, at hydrophobic point, hydrophobic pipe fitting is installed, the water of condensation fairlead of hydrophobic pipe fitting is connected to drain valve group, the condensate water discharge of drain valve group is introduced the sump unit of hydrophobic well chamber, and drainage sump chamber and drain valve group well chamber are separate.In startup running, need operating personnel to enter into hydrophobic well valve group well chamber, manually open the bypass valve of hydrophobic valve terminal and close hydrophobic branch valve, guarantee that initial start stage water of condensation can be discharged to sump unit by static pressure, after startup heating coil completes, need operating personnel again to enter into hydrophobic well chamber, close the bypass valve of hydrophobic valve terminal and open hydrophobic branch valve, start regular hydrophobic function in pipeline performance process.Water of condensation in sump unit needs operating personnel to utilize the regular pump drainage of submersible pump.This hydrophobic point builds and the method for operation exists the deficiency that investment is large, operation is loaded down with trivial details, manual work workload large, line service amount is large, and often due to the defective well chamber ponding that causes of well chamber sealing, valve group seriously corroded, service life of equipment shortens greatly, urgently improves.
Summary of the invention
The object of this invention is to provide a kind of non-maintaining direct-burried prefabricated thermal insulation pressure reduction white-out water vapor pipe fitting, integrate hydrophobic, draining and hydrophobic well chamber function, exempt the upkeep operation of later stage water-pumping/draining, alleviate relevant operating personnel's labor intensity, improve the operating condition of hydrophobic point.
For achieving the above object, the present invention is achieved through the following technical solutions:
Non-maintaining direct-burried prefabricated thermal insulation pressure reduction white-out water vapor pipe fitting, comprise water collect tank, forced-ventilated one-way valve, working pipe linkage section and collector pipe, water collect tank is located at the below of working pipe linkage section, one end of collector pipe is connected with working pipe linkage section is vertical, the other end of collector pipe is plugged on water collect tank, described forced-ventilated one-way valve is arranged on collector pipe, on water collect tank, be also inserted with hydrophobic fairlead and forced-ventilated for airduct, forced-ventilated is positioned at the top of water collect tank for the outlet of airduct, the entrance of hydrophobic fairlead is positioned at the bottom of water collect tank, the entrance of described control valve airduct, forced-ventilated is all located at the top of working pipe linkage section for the entrance of airduct and the outlet of hydrophobic fairlead, working pipe linkage section, water collect tank, forced-ventilated connects into an entirety for airduct and hydrophobic fairlead by thermal insulation layer and steel closed shell.
The two ends of described working pipe linkage section respectively minimum exposed 150mm are used for being connected to relevant steam line.
Compared with prior art, the invention has the beneficial effects as follows:
1) the present invention is applicable to running temperature below 350 ℃, on the direct-burried prefabricated thermal insulation steam line of working pressure below 2.5MPa, by the organic assembling of water collect tank, forced-ventilated one-way valve, hydrophobic fairlead and corresponding airduct, can realize the function of hydrophobic, draining and hydrophobic well chamber, for dredging out along journey water of condensation and starting the discharge of water of condensation simultaneously.
2) in service needs artificially safeguards and draining, save the construction investment of the hydrophobic well of steam pipe line chamber, and having reduced hydrophobic well chamber makes regular check on and the expense of draining, reduce construction cost, accelerate engineering construction progress, reliable, good economy performance, has obvious Practical significance.
