The utility model plays the effect of U type water seal because cylindrical shell is set to the U type to gas, and water seal height plays a water seal effect in the hydathode, and water plays secondary water seal effect in the U type tube body, has the effect of dual fail-safe.In the leading portion standpipe of U type tube body, be provided with the ball float of the soft anticorrosion cushion rubber of band shape, reliable fit by soft anticorrosion cushion rubber of annular and the anticorrosion flange annular distance of lightweight on the ball float, play the effect of closing or opening the fluid passage, thereby the control fluid flows, and has avoided gas to external leakage.
What time following the concrete characteristics of this programme also have:
1, soft anticorrosion cushion rubber casting of annular is an one on ball float and its, the matching of band preserving and sealing circle flange annular distance with its below, its effect has two aspects: the one, and when puncturing U type tube body water level, water seal reduces, ball float descends rapidly and closes the fluid passage, and gas pressure is big more in the pipeline, and it closes tight more.The 2nd, obstruction is arranged when gas pipe line, when cleaning by the blowback hole flushing on the hydathode, ball float and go up the soft anticorrosion cushion rubber of annular with matching of the band preserving and sealing circle flange annular distance of its below, can play seal action again.
2, be provided with the flange filter screen above the ball float in the leading portion standpipe of U type tube body, its effect has three aspects: the one, filter the impurity in the water of condensation, and the 2nd, the height that the control ball float moves, in case gas leakage is arranged, ball float can cut off coal gas rapidly.The 3rd, when preventing to be negative pressure in gas pipe line or the hydathode with ball float suction drain device.
3, above the ball float in the back segment standpipe of U type tube body the buoy indicating arm is set, is used for reflecting the water level height of hydathode or the state that water seal punctures.
4, at U type tube body middle part the connecting tube and the control of restarting leakage preventer is set
Valve, this setting is played starter gate valve and the effect of the valve that resets: during startup, to the hydathode water filling, the control valve of opening on connecting tube makes the water in the hydathode flow into the back segment standpipe of U type tube body by the ball float in the leading portion standpipe of the curved reverse impact U type tube body of U type, ball float is floated, and device starts; After water seal is breakdown, ball float falls to tightly being pressed on the anticorrosion ring center hole, behind hydathode water filling again, the control valve of opening on connecting tube makes the water in the hydathode flow into the back segment standpipe of U type tube body by the ball float in the leading portion standpipe of the bend pipe reverse impact U type tube body of U type tube body, ball float is separated with band preserving and sealing circle flange annular distance, thereby reach the purpose that restarts leakage preventer.
5, material and size requirement: the material of the ball float in the leading portion standpipe of U type tube body is an expanded polypropylene, possesses soft corrosion-resistant requirement, and diameter is 50mm; The material of the ball float in the back segment standpipe of U type tube body is: stainless steel, possess the corrosion-resistant requirement, and diameter is 50mm; Flange seal circle and the annular distance material at flange seal circle center are: teflon, possess soft corrosion-resistant requirement, and the annular distance diameter at flange seal circle center is 50mm.
