Abstract
The utility model relates to a light diving respirator, belonging to the improvement of the technology of a diving device. The utility model comprises a high-pressure air bottle, a back support group, and a set of improved safe decompression air supply device composed of a reducer, air supply adjustors, a middle pressure guide pipe and a safety valve, wherein, the reducer is connected with the air supply adjustors through the middle pressure guide pipe; the reducer is provided with a plurality of interfaces provided for connecting with three air supply adjustors. The safety valve is arranged in the interface of the safety valve of the reducer. The arrangement of the safety valve further enhances the safe performance of the light diving respirator. The safety of a diving person and an instrument is ensured. Since plastic materials are adopted by the casing of the air supply adjustors, the back support, etc., the total weight is lightened.
Description
The utility model belongs to the technological improvement of underwater breathing apparatus.
The coastal line of China is very long, and marine resources are very abundant, asks for the inexorable trend that resource is economic development to the ocean, by the diving equipment, can be engaged in activities such as resource exploration, archaeology, underwater photography and scuba diving under water under water, diving body-building under water.Domestic diving breathing apparatus safety measure of having produced is not well established at present, corrosion resistant performance is poor, and single unit system is heavier.
The purpose of this utility model provides a kind of in light weight, withstanding corrosion, safe and reliable light diving breathing apparatus.
The utility model is made up of high-pressure gas bottle, back bracket group, bottle valve and safety relief gas feeder.The safety relief gas feeder is made up of pressure reducer, safety valve, middle pressure conduit and gas supply regulator.The bottle valve of high-pressure gas bottle is connected with the pressure cap of pressure reducer, and twists solid with handle.Pressure reducer interface of the present utility model is many, can be for connecing 3 gas supply regulators, therefore can for 1-3 people under water (in 40 meters) be engaged in under-water operation and various underwater movement.Safety valve is arranged in the relief valve connection of pressure reducer.Pressure reducer links by middle pressure conduit and gas supply regulator.
During use, open bottle valve, the high pressure gas in the high-pressure gas bottle (20-2MPa) enter in the relief chamber of pressure reducer by valve base (spray orifice that valve is chewed), by the equilibrium activity of piston and the stressed generation of piston spring, form one 0.8 in the relief chamber
± 0.1Stable middle pressure of MPa.Because submerged depth does not wait, cavity pressure is corresponding to change, 10 meters of every submerged depths, and cavity pressure just increases 0.1MPa automatically, and pressure keeps relative stability.High pressure gas drop to 0.8
± 1When pressing among the MPa, enter gas supply regulator by middle pressure conduit again.When the diver is air-breathing by the mouth tool in the air feed adjusting, form relative negative pressure in the air supply chamber, the diaphragm in the gas supply regulator caves in, force the upper end of lever to move down, make valve opening, medium pressure gas is through decompression for the second time, flow in the air supply chamber, in by this mouthful tool pneumatic transmission being entered the mouth again.During dive, external pressure is greater than the air feed intraventricular pressure, and diaphragm is subjected to hydraulic pressure and caves in, and the compressing lever makes valve opening, increases air feed automatically, reaches the inside and outside weighing apparatus that flattens.Stop when the diver is air-breathing, or dive is when stopping, internal and external pressure balance, valve closes envelope, stops air feed.When breathing or diver when rising, the interior pressure of air supply chamber is greater than extraneous hydraulic pressure, and outlet valve is opened, and unnecessary gas and breath are discharged in air supply chamber the extraneous water.So gas supply regulator can automatically adjust with diving depth and respiratory movement, adjusting the pressure balanced while, can need regulate gas supply flow according to human body again, it is comfortable that the diver is breathed under water.
The housing of gas supply regulator of the present utility model, back bracket have adopted withstanding corrosion, high-temperature resistance plastice, and not only quality is good, and cost is low, have also reduced the weight of diving breathing apparatus.Spring in the utility model has all been done qualitative processing, through 1 * 10
5Fatigue life, cyclic test was qualified, did not have corrosion through 72 hours salt spray tests.Adopt phosphatization in the bomb, adopt the electrostatic spraying new process outward, improved antiseptic property, prolonged service life.
Accompanying drawing 1 is a surface structure scheme drawing of the present utility model, and Fig. 2 is the pressure reducer structural representation, and Fig. 3 is the safety valve structure scheme drawing, and Fig. 4 is the gas supply regulator structural representation, and Fig. 5 is the A-A diagrammatic sketch of gas supply regulator.The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model is made up of high-pressure gas bottle 1, back bracket group 7, bottle valve 2 and safety relief gas feeder.The supporting plate of back bracket group 7 is fixed on the high-pressure gas bottle 1.Bottle valve 2 is arranged on the air extractor duct end of high-pressure gas bottle 1.The safety relief gas feeder is made up of pressure reducer 3, safety valve 4, gas supply regulator 6 and middle pressure conduit 5.Pressure reducer 3 is made up of handle 8, coupling link 9, pressure cap 12, filter 11, shutter spring 13, valve base 14, valve body 18, piston 15, piston spring 16 and adjustment cap 17.Piston 15, piston spring 13 are packed in the valve body 18, adjust cap 17 with screw thread and valve body 18 bindings.Valve base 14, shutter spring 13, in the valve body 18 of packing into, filter 11 is placed on the shutter spring 13, is fixed with pressure cap 12.Pressure cap 12 and valve body 18 are with threaded connection.Handle 8, coupling link 9 and pressure cap 12 are with threaded connection.Pressure cap 12 links with bottle valve 2, and twists solid with handle 8.
In the relief valve connection 10 of pressure reducer 3, be provided with safety valve 4 in order to improve safety performance and safety method.Safety valve 4 is made up of valve body 20, spring 21, valve 22O shape seal ring 24, upper cap nut 23, pack into the front end of inner chamber 19 of valve body 20 of valve 22, spring 21 is contained on the valve 22, and upper cap nut 23 is connected with valve body 20 with screw thread, and spring 21 withstood, O-ring seals 24 is enclosed within on the valve body 20.
When the diver dives under water, open bottle valve 2, the high pressure gas in the high-pressure gas bottle 1 enter the relief chamber of pressure reducer 3 by valve base 14, because the equilibrium activity of piston 15 and piston spring 16 stressed generations produces one 0.8 in the relief chamber of pressure reducer 3
± 0.1Stable middle pressure of MPa, this medium pressure gas enters gas supply regulator 6 by middle pressure conduit 5 again.When diver's through port tool 33 is air-breathing, form relative negative pressure in the air supply chamber 32, diaphragm 29 caves in, force lever 30 upper ends to move down, make valve opening, in calm the anger after air valve seat 25 carries out being decompressed to normal pressure the second time, flow in the air supply chamber 32, through port tool 33 is sent in diver's mouth.The carbon dioxide of discharging is discharged in the extraneous water effusion water surface by breathing valve 34.During dive, external pressure is greater than pressing in the air supply chamber 32, and diaphragm 29 is subjected to hydraulic pressure and caves in, and compressing lever 30 makes valve opening, increases air feed automatically, reaches the inside and outside weighing apparatus that flattens.Stop when the diver is air-breathing, or dive is when stopping, internal and external pressure balance, valve closing stops air feed.In a single day malfunctioning when pressure reducer 3, cause secondary pressure to increase, when surpassing specified value, over-pressure gas can be entered in the water by safety valve 4, to protect the safety of the person and utensil.
