Description
Technical field
The utility model relates to chemistry, metallurgical class, oil, coal gas and coking industry; Containing the industrial gas ejector of carbon monoxide, espespecially a kind of gas pipe line liquid seal device.
Background technique
Gas pipe line fluid-tight is exactly make the height of water in gas pressure and water seal reach pressure balance by certain water level, with the condensed water got rid of in coal gas or the sealing keeping gas collecting tube, general said water seal should refer to the water seal of gas pipe line, effect is the water in purging line, requirement is the degree of depth (static pressure of formation) that liquid-discharging tube inserts in water, the pressure of gas in pipelines must be greater than, one is also had to be that gas pipe line is before burner, water seal is installed, prevent gas pressure too low or stop suddenly coal gas time, there is tempering, the not water seal of same-action, purposes is different, principle and structure are also different, water seal mainly divides two classes, one is overflow water seal, water seal height and the Inserting Tube degree of depth are determined by technological requirement and Equipments Setting, in order to discharge ponding or prevent equipment superpressure, can from equipment pressure release during superpressure, two is maintenance water seals, in order to completely cut off with system or miscellaneous equipment, overhaul after equipment carries out replacing and blow down.
The water seal of prior art is all delivery pipe arm is directly inserted below tank liquid level form water seal usually, can effectively seal, play explosion-proof, safe effect, but once gas pressure is excessive in gas pipe line, coal gas will be pressed into tank and cause leakage, once pipeline leaking from tank of forming that instantaneous pressure coal gas will be a large amount of, cause security incident.
Summary of the invention
A kind of gas pipe line liquid seal device is provided for the problems referred to above the utility model, this device structure reasonable standard, easy to operate, effectively can carry out fluid-tight to gas pipe line, when coal gas effectively can be imported gas holder by pipeline formation instantaneous pressure, coal gas be collected to process later.
For solving the problems of the technologies described above, the utility model provides a kind of gas pipe line liquid seal device, comprise delivery pipe, arm, spring, sealing bucket, bellows, water tank, piston, gas holder, it is characterized in that: bottom delivery pipe, be provided with arm, arm outer wall top is provided with fixed block, fixed block bottom connects sealing bucket by spring, branch pipe wall is provided with back-up ring, back-up ring bottom is provided with piston, piston base connects the thin end by spring, the thin end, is arranged on sealing bottom of the barrel, arm outer wall bottom is provided with seal ring, sealing bucket upper inside wall is provided with flange, sealing bottom of the barrel connects water tank by bellows, water tank upper is connected with gas holder.
As further improvement of the utility model, bottom described seal ring, be provided with seal ring.
As further improvement of the utility model, in the middle part of described sealing bucket, be provided with fixing frame.
Working principle:
The utility model is by rational structural design, fluid-tight effect is formed by injecting water in sealing bucket, when delivery pipe inside forms instantaneous pressure, in pipeline, coal gas promotes piston movement by spring picture sealing bucket thin end transmission of pressure, when pressure is excessive, the thin end, is damaged, the water of sealing bucket inside flow in water tank, coal gas flows to gas holder and stores, the spring that fixed block bottom is arranged pulls sealing bucket up to move, the seal ring of arm outer wall is formed with the flange of sealing bucket inwall and coordinates, female seat circle and flange are formed and are sealed and matched, due to the setting of bellows, effectively sealing bucket can be pulled, arranging of fixing frame can effectively prevent piston from dropping to water tank upper blocking water tank.
The utility model compared with prior art has following beneficial effect:
1, this device structure reasonable standard, easy to operate, effectively can carry out fluid-tight to gas pipe line, collects to process later when coal gas effectively can be imported gas holder by pipeline formation instantaneous pressure to coal gas;
2, the spring that fixed block bottom is arranged pulls sealing bucket up to move, and the seal ring of arm outer wall is formed with the flange of sealing bucket inwall and coordinates, and female seat circle and flange are formed and be sealed and matched, and due to the setting of bellows, can effectively be pulled by sealing bucket.
