Description
Technical field
The present invention relates to a kind of air inflation raft measuring cell.
Background technology
Life-float is that boats and ships are equipped with in emergency circumstances region out of danger or from the lifesaving appliance of ship in distress emergency escape and equipment, also to take precautions against natural calamities equipment special as flood fighting.
Life-float is the modern raft ship with synthetic material, comprises the materials such as metal tube, complex pipe, plastic tube, synthetic resin or fiberglass pipe and makes.
Life-float bow portion is provided with head line, and it is the hawser playing connection function between life-float and fixture.Life-float will keep normal floating state after carrying sufficient rated crew member and whole accessory.The tube chamber of life-float floats tire and at least should be separated into 2 independent air chambers, and the setting of floating tire should be able to when arbitrary air chamber be damaged, and life-float still can normally use.
Life-float ship general assembly (TW) should more than 185kg.Outward appearance should be well-balanced, uniform color, must not have come unglued, defect that the impact such as absciss layer, bubble uses, can deposit and unlikely damage under-10 ~+65 DEG C of environment temperatures, and can use within the scope of-1 ~+30 DEG C of coolant-temperature gage.
Life-float at ordinary times packaging and storing in fiberglass cartridge, life-float is arranged on the special raft frame of ship side, raft directly can be thrown in water, life-float both can be shaped automatically in inflation, took for distress personnel, if boats and ships sink too fast, raft is had little time to be thrown in water, when boats and ships sink under water certain depth time, the hydrostatic release unit on life-float frame can be automatically-unhooked, discharges life-float.
Barometrical effect is the intrasystem pressure of instruction, usually adopts mercury gage.Be filled with water silver in heavy sheet glass pipe, and pipe is equipped with mobile scale behind, and mobile scale is by zero degree adjustment meeting the mercury plane place in most piston glass tube B, and when drawdown pump works, A pipe mercury column declines, and B pipe mercury column rises, and both differences, show the pressure of system.Must be noted that during use not make water or booty invade in measuring cell, bubble also must not be had in mercury slug to exist, otherwise impact is measured the accuracy of pressure.The manometric advantage of closed mercury is light and handy convenience, but if any residual air or when introducing water or impurity, then accuracy is affected.This measuring cell will strictly control not allow air enter when loading mercury, method first pure mercury is put into little round-bottomed flask, then the efficient oil pump be connected with measuring cell is pumped to 13033Pa (10-1mmHg) below, and pat little flask, bubble in pump is overflowed, with hair dryer low-grade fever glass tube, gas is extracted out, then mercury is injected U-shaped pipe and stop bleeding and put into air.Open type mercury manometer dress mercury is more convenient, and more accurately, the ratio degree of glass tube used will more than 760mm.The difference of the height of U-shaped pipe two-arm mercury column is the difference of pressure in common pressure and system.
The kind of life-float is varied, Chinese patent ZL201320649937.2 discloses a kind of life-float arranging relief hole, floating tire is provided with at the bottom of this life-float raft, described floating tire comprises floating tire and tire of floating downward, described floating tire and tire of floating downward overlap the upper end at the bottom of raft, described high-pressure inflater is arranged on floating tire and floats downward between tire, floating tire is provided with the arc awning across life-float, described awning and described floating tire junction are provided with weep hole, reflective tape is pasted with outside described awning, the ponding bag of fresh water is contained at described awning inside suspension, outer armrest rope is had in tire arranged outside of floating downward, interior manrope is provided with inside floating tire, at the bottom of raft, bottom hung has compression water bag, raft bottom is provided with relief hole, described relief hole is by outside at the bottom of inner at the bottom of soft pipe connection raft and raft, the inside and outside environment of life-float is made to carry out unimpeded, greatly facilitate the gas replenishment process of high-pressure aerated bottle to life-float like this.
China Patent Publication No. CN 104085514 A discloses a kind of lifesaving appliance and life-float, described lifesaving appliance is made up of the first circle body and the second circle body, first circle body and the second circle body are integral type or are connected by interface components, the first end of the first circle body is connected with the second end of the second circle body and inflates, forms ring life buoy, first circle body and the second circle body are respectively arranged with the first coupling arrangement and the second coupling arrangement, described life-float is combined by the first coupling arrangement and the second coupling arrangement by lifesaving appliance described in several simultaneously.Lifesaving appliance provided by the invention, the ring life buoy of one man relief or use can be formed, also the life-float facilitating many people to rescue and transport can be formed, simple for structure, use flexibly, high to the condition of a disaster change adaptability, life-float provided by the present invention, size is adjustable, and prevents part gas leakage to cause the non-serviceable situation of whole life-float.
It seems from above life-float technical scheme, original liferaft inflate pressure test must be carried out step by step, first life-float is inflated, inflation can only be stopped by estimating force value, be connected on by air intake opening on sphygmomanometer and carry out pressure test, force value can not disposable accurate acquisition, needs repeatable operation, complicated operation, reliability is low.
Summary of the invention
Object of the present invention, is to overcome above-mentioned limitation, thus provides a kind of easy to operate, and reliability is high, economical and practical air inflation raft measuring cell.
