Description

Leak-proof gas drainer

technical field

The utility model relates to a gas drainer, in particular to an anti-leakage gas drainer.

Background technique

The principle of the gas drainer is to seal the drain pipe at the lower part of the gas pipeline with a certain height of water, so that the gas will not leak, and the gas condensate in the pipeline can be automatically discharged. The water at a certain height is calculated. Under the condition of normal gas pressure, the drainer can operate safely, but when the gas pressure fluctuates and causes the water level of the drainer to drop or there is sewage for other reasons, the water is not enough to seal the gas, and finally a large amount of gas leaks and an accident occurs.

Utility model content

In order to overcome the above existing problems, the utility model provides an anti-leakage gas drainer which is easy to maintain and can make the gas pipeline drainer run safely.

The technical scheme that the utility model adopts is:

The anti-leakage gas drainer includes a drainer body, which is divided into four chambers a, b, c, and d sequentially from left to right through a partition, and the upper end of the chamber a is connected to an inlet valve and is equipped with The exhaust port, the inlet valve connecting pipe reaches the bottom of chamber a, the upper part of the partition between chamber a and chamber b is provided with a communication hole, the upper ends of chambers b and c are provided with inspection holes and the interior Equipped with an anti-leakage device, the anti-leakage device includes an anti-leakage pipe and a floating ball connected by a traction rope, a sealing baffle, and the sealing baffle is used to close or open the anti-leakage pipe, and the anti-leakage pipe is arranged at b The bottom of the chamber and chamber c are connected to chambers b, c and chambers c, d. The bottoms of the three chambers a, b, and c are provided with sewage hand holes, and the chamber d is provided with longitudinal partitions to Chamber d is divided into two chambers d1 and d2, the partition plate forms a communication hole with the top of chamber d, and an overflow port is provided below chamber d2.

The utility model has the advantages: the drainer has four chambers, providing space for gas blocking, the middle two chambers are equipped with anti-leakage devices, and the right chamber is equipped with partitions, which provide multiple guarantees for preventing gas leakage .
