Description
One, technical field
The present invention relates to a kind of product performance test device, a kind of leakage tester of life jacket of saying so more specifically.
Two, background technology
Life jacket is one of personal life-saving appliance indispensable on the boats and ships, is the last resort that personnel save oneself running under the perils of the sea or other emergency situation.Just because of life jacket is so important, can its security effectively be used for life jacket, and can more save life be a vital factor.Common life jacket is that polyfoam or other high buoyant material are made unlimited vest or pullover type with painting cloth, when personnel dress and use except that head whole body be immersed in the water substantially, therefore, if after dressing such life jacket and fall into water the winter of cold, the drowning people will soon be because of forfeiture body temperature threat to life.International Maritime Organization (IMO) is at this shortcoming of common life jacket, and regulation must be equipped with the monoblock type immersion suit that equates with driver and crew's number from July 1st, 2006 on every boats and ships.This immersion suit uses waterproof coldproof material and high buoyant material to make the whole immersion suit of whole body protection according to body shape, the user only has face to expose outside the immersion suit, and the facial edge of opening of immersion suit adopts resilient material and the facial sealing of user to fit, this immersion suit not only can allow the user swim on the water surface, and completely cut off health and contacted with the direct of water, the user can swim in the long period in the water of low temperature and not reason body temperature reduce threat to life.In order to improve the security of this monoblock type immersion suit, International Maritime Organization (IMO) has stipulated detailed safety test index, and wherein the immersion suit leak-testing is topmost test event, and the regulation leak-testing must promptly be carried out full inspection at every immersion suit.At present, the monoblock type immersion suit of selling on the market, its leak-testing does not adopt strict test condition, there is not standardized testing apparatus yet, the most general method of testing is immersed in the water after allowing the tester dress immersion suit exactly, whether the tester only has water to infilter in the immersion suit with somatosensory, or checks in the immersion suit whether the water mark is arranged after the water outlet, judges its sealing with this.This method of testing efficient is very low, immersion suit be put on and restrainted to one of every test just must the tester, immerse in the water again and test, and adopt this method test immersion suit to depend on tester's somatosensory or make inspection occur careless omission often because the inner gauffer of immersion suit is more, cause resultant error bigger, and lack the data that quantize, so can not satisfy the security requirement of International Maritime Organization (IMO).
Three, summary of the invention
1, goal of the invention: the immersion suit leak-testing equipment that the purpose of this invention is to provide a kind of high reliability, its every test condition has all satisfied the safety test requirement of International Maritime Organization's regulation, has higher efficient with respect to existing testing apparatus or method, and this device structure is simple, and is very easy to use.
2, technical scheme: a kind of leakage tester of life jacket of the present invention, it comprises inner splint and the external splint that clamps and seal the immersion suit edge of opening, on inside and outside clamping plate, be respectively equipped with two through holes that connect clamping plate, a through hole is provided with gas injection joint therein, on another through hole, be provided with pressure tapping, on inner splint, be provided with flush bolt, the relevant position is provided with the through hole that flush bolt can pass on the external splint, and the flush bolt end is provided with and screws to seal the nut of inside and outside clamping plate.
Inside and outside clamping plate can be the tabulars that is complementary with the immersion suit opening, also can be and be complementary bowl-shape of immersion suit opening or shape that other is suitable.
Gas injection joint and pressure tapping can be separately positioned on two through holes of inner splint, and after two clamping plate clamped, two joints passed two through holes on the external splint; Also can be separately positioned on two through holes of external splint, corresponding gas injection joint and the pressure tapping setting respectively of two through holes of inner splint is so that the test gas free flow.
On the contacted sealing surface sealing gasket is being set on the inside and outside clamping plate, can the enhanced leaktightness effect, the possibility that reduces to leak.
Gas injection joint can external electric air pump gas injection, if immersion suit is to make regular check on and lack under the situation of electric air pump hand air pump gas injection that also can be easy to use doing on the boats and ships.
Can also be provided with the cavity or the through hole that hold slide fastener on the immersion suit on the external splint, when using two clamping plate to compress immersion suit, and after inflation makes the immersion suit bulging, can not influence sealing because of slide fastener perk roof pressure external splint.
The monoblock type immersion suit is in order to improve sealing property, after the user dresses and pulls on the pressure-sealing zipper that the chest belly is convenient to dress, only leave facial opening, this edge of opening adopts resilient material so that itself and user's face fit tightly and play sealing function, and because immersion suit has adopted insulation material to make, thereby avoid the too fast decline threat to life of user's body temperature in water.When using the sealing of leakage tester test monoblock type immersion suit of the present invention, do not need personnel to dress, only need to put into inner splint in the opening inboard, pull on waterproof slide fastener again, then buckling external splint compresses the immersion suit opening, nut is tightened on the flush bolt, two clamping plate are clamped the immersion suit edge of opening and sealing, by electronic or hand air pump at the gas injection joint injecting gas, when the force value of the gas of input rated pressure or input gas reaches on the tensimeter ratings, whether close gas check valve, saponification liquid is spread upon particularly each seam crossing of immersion suit surface, observing has bubble to produce with check immersion suit sealing property.
3, beneficial effect: the present invention clamps by two clamping plate and sealing immersion suit opening, importing gas again makes the specified test pressure of the inner maintenance of immersion suit to test its sealing property, satisfied the safety test requirement of International Maritime Organization's regulation, in test process, do not need personnel to dress immersion suit, has higher efficient with respect to existing testing apparatus or method, and this device structure is simple, very easy to use, reliability also the sort ofly only wants high many with tester's somatosensory sealing property or the test mode of checking immersion suit internal water mark with respect to original.
