Background technique
At present, for hydrophobic, the draining of direct-burried prefabricated thermal insulation steam pipe line in engineering, common practices is at the hydrophobic pipe fitting of hydrophobic installation, the water of condensation fairlead of hydrophobic pipe fitting is connected to drain valve group, the condensate water discharge of drain valve group introduces the sump unit of hydrophobic well room, and drainage sump chamber and drain valve group well room are separate.In startup optimization process, operating personnel is needed to enter into hydrophobic well valve group well room, manually open the bypass valve of hydrophobic valve terminal and close hydrophobic branch valve, ensure 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 room, 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.There is the deficiency that investment is large, operation is loaded down with trivial details, manual work workload is large, line service amount is large in this hydrophobic method built and run, and often cause well room ponding because the sealing of well room is defective, 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 water drainage steam fittings, integrate hydrophobic, draining and hydrophobic well room function, exempt the upkeep operation of later stage water-pumping/draining, alleviate the labor intensity of relevant operating personnel, 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 water drainage steam fittings, 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, water collect tank is also inserted with hydrophobic fairlead and forced-ventilated confession airduct, forced-ventilated supplies the outlet of airduct to be positioned at the top of water collect tank, 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 minimum exposed 150mm of difference of described working pipe linkage section is used for being connected with associated steam pipeline.
Compared with prior art, the invention has the beneficial effects as follows:
1) the present invention be applicable to running temperature below 350 DEG C, working pressure is on the direct-burried prefabricated thermal insulation steam line of below 2.5MPa, by the organic assembling of water collect tank, forced-ventilated one-way valve, hydrophobic fairlead and corresponding airduct, the function of hydrophobic, draining and hydrophobic well room can be realized, for dredging out along journey water of condensation and starting the discharge of water of condensation simultaneously.
2) artificial maintenance and draining is not needed in running, save the construction investment of the hydrophobic well room of steam pipe line, and decrease hydrophobic well room and make regular check on the expense with draining, reduce construction cost, accelerate engineering construction progress, reliable, good economy performance, has obvious Practical significance.
