Description

A kind of seven flourin propane fire extinction system container value that can automatic alarm
Technical field
The utility model belongs to the fire prevention field, particularly relates to a kind of seven flourin propane fire extinction system container value that can automatic alarm.
Background technology
Heptafluoro-propane (chemical formula is CF3CHFCF3) is a kind ofly to take inhibition as main; have the clean gas extinguishing chemical of physics fire extinguishing function concurrently; have colourless, tasteless, low toxicity, non-conductive, do not pollute protected object; can not cause the characteristics such as damage to property and accurate facility, therefore utilize heptafluoro-propane to be widely used in the self-extinguishing in the places such as machine room, change switchgear house, transformer room, archive office as the gas extinguishing system of extinguishing chemical.Seven flourin propane fire extinction system commonly used mainly consists of parts such as gas cylinder, container value, playpipe, nozzle and selector valve groups at present.Fig. 1 is gas cylinder and container value bonding state schematic diagram in above-mentioned seven flourin propane fire extinction system.Fig. 2 is the container value side structure schematic diagram shown in Fig. 1.Fig. 3 be in Fig. 1 A-A to cutaway view.Fig. 4 be in Fig. 2 B-B to cutaway view.As shown in Fig. 1-Fig. 4, this container value 10 is arranged on the gas outlet of gas cylinder 11, and it mainly comprises valve body 1, cylinder 2, spring 3, piston 4, valve rod 5, main valve lid 6, main valve 7, valve assembly 8 and safety cap assembly 9; Wherein the lower end of valve body 1 is formed with a steel cylinder connector C who is connected with the gas outlet of gas cylinder 11, the middle part, upper surface has been formed through a valve rod hole has been set, be formed with a jet B on upper portion side wall, lower sides is formed with respectively a solenoid valve interface D and a pressure relief opening E simultaneously, and the top intracavity diameter of valve body 1 is less than the lower lumen diameter, form thus a stage between the inner peripheral surface upper and lower; Cylinder 2 is and covers shape, be arranged on the end face of valve body 1, and the middle part, upper surface is formed with a driving gas air inlet A; The middle part of valve rod 5 is run through in the mode that can move up and down the valve rod that is arranged on valve body 1 and Nei, top, hole is set is positioned at cylinder 2 inside, and bottom is positioned at valve body 1 inside; Spring 3 is helical spring, is enclosed within the upper external of valve rod 5; Piston 4 is arranged on the upper end of valve rod 5; Main valve lid 6 and 7 lower ends that are arranged on valve rod 5 of main valve, and be positioned at the stage downside of valve body 1; Valve assembly 8 and safety cap assembly 9 are arranged on respectively on solenoid valve interface D and pressure relief opening E.Before use, at first the steel cylinder connector C on container value 10 is connected on the gas outlet of gas cylinder 11, pass through afterwards jet B to the interior injection seven flourin propane fire extinction of valve body 1 agent 12, under the effect of seven flourin propane fire extinction agent 12, main valve lid 6 and main valve 7 will move down and be separated from the stage place of valve body 1, be with ovable valve stem 5 and piston 4 also together to move down simultaneously, thereby Compress Spring 3, at this moment seven flourin propane fire extinction agent 12 will enter into through the steel cylinder connector C on valve body 1 inside of gas cylinder 11, until the filling extinguishing chemical to required weight, stop injecting, at this moment under the resilient force that main valve lid 6 and main valve 7 will apply at spring 3, reset, thus jet B and steel cylinder connector C are kept apart, thereby extinguishing chemical 12 is encapsulated in gas cylinder 11, then the driving gas air inlet A on cylinder 2 is connected with driving bottle by pipeline, jet B and playpipe on valve body 1 are joined simultaneously.When quasi-operating status, main valve lid 6 and main valve 7 on container value will rely on the elastic force of spring 3 tightly to be against the stage place of valve body 1, therefore jet B and steel cylinder connector C are in mutual isolation, and at this moment the extinguishing chemical 12 in gas cylinder 11 just can't discharge by jet B.When breaking out of fire, come the high pressure nitrogen as driving gas of self-driven bottle the driving gas air inlet A from container value 10 to be entered to the inside of cylinder 2, thereby promote piston 4 downwards, Compress Spring 3 thus, under the drive of piston 4, valve rod 5, main valve lid 6 and main valve 7 also will together move down, main valve lid 6 and main valve 7 are separated from the stage place of valve body 1 as a result, thereby jet B and steel cylinder connector C are interconnected, therefore the extinguishing chemical 12 in gas cylinder 11 will pass through steel cylinder connector C successively, the internal cavity of valve body 1, jet B and playpipe outwards are discharged in corresponding guard plot, to reach the purpose of fire extinguishing.But there is following point in the container value of this prior art: when quasi-operating status, extinguishing chemical should be sealed in gas cylinder 11 fully, and any leakage must not be arranged, otherwise will cause fire extinguishing system to lose efficacy.But, be subject to the impact of external environment and container value 10 self structure, extinguishing chemical 12 in gas cylinder 11 likely can leak from container value 10, and current monitoring means is to utilize Pressure gauge to show the pressure in gas cylinder 11, this method needs the staff initiatively to observe could to find, but the limited amount due to the staff, and system scope is larger, therefore make pressure leakages not to be found in time, like this after leaking appears in extinguishing chemical 12, once fire occur, this gas extinguishing system can't provide the extinguishing chemical 12 of enough consumptions, thereby cause Loss of Life and property.
Summary of the invention
