For water sealed tank, " should arrange U-shaped spill pipe (must not establish cutting-off valve), the water seal height of spill pipe should be more than or equal to the maximum operating pressure (gauge pressure) of gas-phase space in 1.75 times of water sealed tanks to code requirement, and overfall tube diameter is minimum is DN50.Its high some place pipeline lower inner surface should be in same level height with the water seal liquid level required." for current torch project; the system pressure in water sealed tank is increasing; maximum operating pressure even reaches more than 50KPa; if according to the spill pipe of the existing form of criterion settings; the foundation elevation of water sealed tank can reach more than 7.5m; for general horizontal water sealed cans, height of foundation reaches more than 7.5m, and the infrastructure cost increased also is high.
Model utility content
For the technical problem that the water sealed tank infrastructure cost solving prior art existence is high, the utility model provides a kind of U-shaped spill pipe of built-in type, adopts buried mode to install spill pipe, not only reduces the height on water sealed tank basis, infrastructure cost is low, and maintenance is all very convenient.
For achieving the above object, the technological scheme that the utility model adopts is: buried spill pipe, comprises pre-buried buried pipe and U-shaped outlet pipe, and built-in pipe needs to bury in advance puts preassignment place, fixing for single unit system.The bottom of pre-buried buried pipe is pre-buried to below ground, standpipe is fitted with in pre-buried buried pipe, the top of standpipe extends to the outside of pre-buried buried pipe, standpipe is arranged in pre-buried buried pipe by the first flange group, outlet pipe comprises the first vertical tube, bending tube and the second vertical tube, first vertical tube is connected by bending tube with the second vertical tube, first vertical tube to be inserted in standpipe and to be fixed by the second flange group, the top of bending tube is communicated with vacuum breaker adapter, the overflow water of the second vertical tube goes out mouth down and arranges, the standpipe part extended to outside pre-buried buried pipe is communicated with S type intake pipe.
When liquid level in water sealed tank exceeds setting value, the overflow water of discharging in water sealed tank enters into standpipe by intake pipe, and the water in standpipe is discharged by outlet pipe.Vacuum breaker adapter is used for the degree of vacuum automatically eliminated in pipeline, makes water cut, prevents the siphonage that may occur.
Wherein, the buried spill pipe of water sealed tank, concrete size, height and structure size calculate according to actual needs to be determined, spill pipe is safety installations, and after careful design, whole equipment safety is reliable.
First flange group comprises flange one and flange two, and flange one is sleeved on the top of pre-buried buried pipe, and flange two to be sleeved on standpipe and to be connected with flange one by many bolts.
Second flange group comprises flange three and flange four, and flange three is sleeved on the top of standpipe, and flange four to be sleeved on outlet pipe and to be connected with flange three by many bolts.
First flange group and the second flange group are used for the connection between pipe, play good sealing and fixed effect.
Wherein, as preferably, vacuum breaker adapter is arranged upward.
