Description
Technical field
The utility model relates to the releasing device of quick release valve in a kind of the inflatable lifesaving appliance assembly, particularly inflatable lifesaving appliance.
Background technique
At present, the safe release device of quick release valve generally adopts the eccentric cam structure in the existing inflatable lifesaving appliance system, starts eccentric cam with drag-line; Make quick release valve striker displacement, further break up the steel cylinder working masks, the tripping force of this its quick release valve of working principle just with the rotation eccentric cam; Striker displacement, working masks broken up and steel cylinder in press all relevant, so its tripping force is very inhomogeneous; Low have 200 ~ 300N, and high have 800 ~ 1000N, under the low temperature extreme case sometimes greater than 1500N; And the ISO15738 standard code, in+65 ℃ ~-30 ℃ temperature ranges, the tripping force of quick release valve should be not more than 150N.So the releasing device of said structure is difficult to reach the industry international standard, the tripping force of inflatable lifesaving appliance gas charging system is unstable, has certain potential safety hazard.In addition; The quick release valve striker that uses at present is only as the usefulness of breaking up (the double insurance of work) diaphragm; After the steel cylinder diaphragm is broken up; Liquid gas in the steel cylinder will overcome the diaphragm back-flexing and retaining could discharge gas behind the resistances such as striker in the middle of the passage, so liquid gas is inhomogeneous in releasing course, phenomenons such as long-pending dry ice obstruction occur through regular meeting owing to diaphragm flexes is inconsistent in the low temperature choosing.
In order to solve above-mentioned deficiency, the patent No. is 200820154230.3, name is called the safe release device and have in the patent documentation of quick release valve of this safe release device, has mentioned that a kind of drag-line is connected with release plug; Release plug is embedded in an end of releasing rod; Releasing rod is contained in the releasing rod fixed base, is arranged with a spring between releasing rod fixed base and the releasing rod, connects a striker on the releasing rod the other end; Striker is provided with hollow section, is equipped with the releasing device of through hole on said striker syringe needle and the hollow section.It is following to draw its working principle according to the said structure description: after release plug is pulled out; The bore of the release plug connecting end of releasing rod just has dwindling to a certain degree; Under the effect of spring, releasing rod will drive striker and break up working masks again, and the tripping force of quick release valve only is stressed between release plug and the releasing rod (striker); So can keep stable tripping force; Generally between 60 ~ 100N, even extreme at low temperatures tripping force can not surpass 150N yet, tripping force can not be lower than 60N to tripping force yet under the high temperature.Its striker is provided with hollow section simultaneously; Be equipped with through hole on said striker syringe needle and the hollow section; Even it is no longer mobile that striker breaks up behind the diaphragm; Liquid gas also can get into through striker head through hole and flow to quick release valve air outlet hole and the air chamber that gets into the inflatable lifesaving appliance in the striker behind the thorax again, and striker keeps its smoothness as the stationary conduit of gas flow and reduces the phenomenon of the long-pending dry ice of generating gasification in the gas flow process.
But as the fast releasing apparatus in a kind of lifesaving appliance, the abominable of its Environmental Conditions, the uncertainty of service time can influence the physical property and the chemical property of himself material to a great extent.Therefore in the above-mentioned patent documentation under this off working state release plug be embedded in releasing rod one end; Release plug is pulled out during working state; The release plug connecting end of releasing rod produces the structure of deformation and the disengaging of releasing rod fixed end, and its poor work stability influences its usability easily; When after striker breaks up diaphragm, no longer moving simultaneously, the words of only establishing through hole at the striker syringe needle can influence the speed of gas flow.
