Description
Technical field
The present invention relates to the gas cylinder technical field, relate in particular to a kind of constant force cylinder valve emergency shutdown system for canned hazardous gas steel cylinder.
Background technique
In the municipal administration of the canned hazardous gas of present domestic use steel cylinder, the chemical industry, because hazardous gas not only has toxicity, explosion hazard, also has severe corrosive, cause pipeline and equipment in the system seepage or leakage to occur, parts need frequent dismounting and change, even break, and can cause a large amount of leakages.Therefore, industry has strict demand to transportation, storage and the use of hazardous gas, and has formulated corresponding safety standard and safety measure, to avoid or to reduce the person, property loss.
The general procedure of processing hazardous gas spillage is: when indoor generation gas leakage accident, the emergency processing personnel need to dress siren suit in the place (outdoor) of safety, put on resuscitation apparatus and enter the gas leakage scene, close first the valve on the gas cylinder, cut off dangerous matter sources, the people withdraws from the room again, falls by the gas treatment that the gas leakage neutralising arrangement will leak, and the people also checks spot failure in the return chamber again.In the practical operation, since operator to the fear of toxic and harmful, have nervous psychology, subjectivity thinks that the valve of closing on the gas cylinder is more tight better, cause operational torque much larger than specified value, damaged artificially unconsciously cylinder valve, can again operate leakage accident when serious, cause the loss of personnel's life and business property; What is more, in breaking out of fire with the place of explosion risk is arranged, can only take passive quarantine measures, can't cut off dangerous matter sources from the source, and consequence is even more serious.
The present another kind of measure of processing the canned hazardous gas spillage of steel cylinder both domestic and external proposes pneumatic valve to be installed gathering steel pipe, and when gas leakage occured, instantaneous closing gathered the steel pipe valve, makes hazardous gas no longer enter follow-up equipment.This cover pneumatic valve can effectively solve gathering the problem of leaking behind the steel pipe, but in recurrent leakage before gathering steel pipe, when occuring such as urgencies such as the perishable parts that easily go wrong most break, can't in time close dangerous matter sources, and make this processing invalid.
Summary of the invention
Deficiency for the prior art existence, the object of the present invention is to provide a kind ofly be directly installed on the cylinder valve, and can be by the emergency shutdown system of remote control, in case the discovery hazardous gas spillage can cut off the hazardous gas source quickly and accurately, stop to leak to enlarge.
For achieving the above object, technological scheme of the present invention is: a kind of constant force cylinder valve emergency shutdown system, it comprises control unit and shutoff device, described shutoff device is installed on the cylinder valve of canned hazardous gas steel cylinder, described control unit is installed away from described shutoff device, by electronic or pneumatic mode, controls described shutoff device, make described shutoff device produce the constant moment of closing, close cylinder valve.
Preferably, shutoff device comprises Power Component, transmitting assemblies and fixing-assembly, and transmitting assemblies connects respectively Power Component and fixing-assembly, and the successively coaxial direction assembling of Power Component, transmitting assemblies and fixing-assembly, forms the tubbiness ectosome.
Preferably, control unit comprise control unit with its monitoring unit that is connected respectively, alarm unit, danger button, described monitoring unit, alarm unit are used for finding dangerous information, in case dangerous information occurs, control unit sends the corresponding actions instruction to described shutoff device, control Power Component output constant moment is finished transmitting assemblies to close the action of gas cylinder valve.
Compared with prior art, the technique effect of technical solution of the present invention is: constant force cylinder valve emergency shutdown system of the present invention can be under the condition that does not change existing equipment, directly be installed on shutoff device on the cylinder valve, by the control unit output of installing away from gas cylinder, produce constant moment loading on cylinder valve, close quickly and accurately cylinder valve, prevent hazardous gas to continue to enlarge.In the operation, personnel do not need to enter the deathtrap, have protected personal security, have reduced device damage, have reduced the environmental pollution that hazardous gas spillage causes.The successively coaxial direction assembling of Power Component, transmitting assemblies and fixing-assembly forms the tubbiness ectosome, and is light and handy compact, is fit to little space and uses.In the municipal administration of using the hazardous gases such as poisonous and harmful, chemical industry, a kind of new measure that toxic and harmful leaks of processing has been proposed.
