Steam trace heat leak proof gas drainer

Product introduction

Steam trace heat leak proof gas drainer is mainly composed of gas drainer body and gas drainer anti-leakage device. Steam heat tracing anti-leakage gas drainer main functions: one is to use the height of the water seal sealed gas, condensate discharge; Second, it can reflect the level of sealing water level in the drainer; Third, once the water seal in the drainer is broken down, the gas device is sealed by the gas drainer to prevent the leakage of gas, to prevent a large number of gas leakage. By controlling the leakage of gas, prevent the occurrence of gas poisoning and fire.

Working principle

The float is made of stainless steel empty cylinder, the specific gravity is lighter than water, the lower part of the rubber cone, and the outer shell rubber cone, forming a sealing surface, when the water level is normal, the gas pipeline drainage device is filled with water, water will be separated from the gas and the atmosphere, with the rise of the water level, the excess water through the leakage device discharge. When the gas pressure is greater than the water seal height of the drainer, the water seal of the drainer is broken down, and the drainage outlet of the leakage prevention device is tightly sealed, so as to prevent the gas leakage.

Selection parameter

1. Installation form horizontal/vertical (maximum)/square vertical installation height, need to leave 1.5 meters, (excluding gate valve) horizontal installation height, need to leave 1.2 meters square installation height can be 1 meters below

2. Heat tracing mode electric heat tracing/steam heat tracing/no heat tracing (annual temperature above 0℃)

3. Water seal height commonly used 4 meters, 3 meters, gas pipe network (most less than 25Kpa) pressure +500mm +800 water seal, and pipe network pressure multiplied by 1.2 times, choose the maximum.

4. Imported commonly used DN50 DN80 DN100 DN125 DN150 DN200 5. Plate thickness has no requirements: 1) usually 8mm. 2) some requirements of the top plate and the bottom plate 10mm, the other 8mm. 3) the standard requirements of the cylinder is not less than 6mm. Pipe fitting shall not be less than 5mm. 6. Not less than carbon steel q235b stainless steel not less than 304
