Description
Affiliated technical field
The utility model relates to coal gas technical field safe in utilization, and is specifically a kind of when low pressure or regional coal gas occurring and exceed standard for gas fittings, facility, gas fittings, facility purged fast the safety installations of nitrogen or steam before cutting off coal gas automatically.
Background technique
At present, be used for device that gas pipe line purges and have only a kind ofly basically, the short tube of a band manually-operated gate promptly is installed on gas pipe line.This " simple blowing cleaner " can only manually connect nitrogen or steam line temporarily and realize purging before maintenance gas fittings, pipeline.Stipulate according to GB6222-2005 " industrial enterprise's gas safety rules ": scurry in steam or the nitrogen tube for preventing coal gas, only when logical steam or nitrogen, could be communicated with steam or nitrogen tube with gas pipe line, when stopping using, should disconnect or stifled blind plate.So when coal gas generation pressure sharply descend, leak, when catching fire, " simple blowing cleaner " is the function that can't realize fast automatic purging.
Summary of the invention
In order to solve the deficiency that existing coal gas blowing cleaner exists, the utility model provide a kind of simple in structure, reflection fast, purge effective coal gas and purge safety installations fast.
The technological scheme that its technical problem that solves the utility model adopts is: this coal gas purges safety installations fast, comprise gas pipe line, mainly be partition apparatus and water injecting device that is connected with partition apparatus and the water supply installation that on gas pipe line, is provided with the V-type water-sealed type, the left side horizontal pipe of V-type water seal is connected with gas pipe line, V-type water seal bottom connects U type waste pipe and be provided with a dynamoelectric water valve door on U type waste pipe, and the water pipe of water supply installation is provided with the dynamoelectric water valve door; Said partition apparatus is made of V-type water seal and the left side horizontal pipe that is connected with the V-type water seal and right side horizontal pipe, is respectively equipped with gas check mortor operated valve on left side and the right side horizontal pipe; Said water injecting device connects water tank by the U type water injecting pipe of V-type water seal top, U type water injecting pipe is provided with the dynamoelectric water valve door, water tank is connected by dunnage with case lid, between leave the gap, water pipe tube head above the case lid is communicated with the case lid plane, and the water pipe that water tank connects above is provided with the dynamoelectric water valve door.
The utility model advantage compared with prior art:
The one, two check mortor operated valves of V-type water seal and both sides are formed reliable partition apparatus, can prevent that fully coal gas from scurrying into the blowing medium pipeline personnel's intoxication accident takes place.
The 2nd, water tank effectively separates with water supply line, can prevent that coal gas or blowing medium from polluting water system.
The 3rd, U type filling pipe is adopted in V-type water seal upper right, can prevent former thereby cause entering in the pipeline air because of the moisturizing valve is not opened, water tank lacks water, Water filling valve are poorly sealed etc.
The 4th, can cooperate the fast shut-off valve together to incorporate the PLC automatic control cabinet into, realize safety control automatically.
