Description
Technical field
The utility model belongs to underwater units structural member technical field, is to be related to a kind of collection inflation, airtight detection, inner chamber pressure
A kind of underwater units that force value is determined and anti-ambient pressure changes, are specifically related to a kind of underwater sealing nacelle bidirectional bearing inflation
Airtight check device.
Background technology
The inner chamber inflation of underwater sealing nacelle and airtight detection, are all carried out separately, using two kinds of different dresses at present
Put.The usual way of current inner chamber inflation is：The dust cap at inflation inlet is removed, will be directly right with manometric gas-charging connection
Quasi- inflation inlet, opens source of the gas and directly inflates.The usual way of airtight detection is：Will be with manometric device, directly alignment inflation
Mouth measurement chamber pressure, pressure value reaches after requirement, removes inflation and detection means, dust cap is reinstalled into original place, then will be whole
Detected in individual sealing cabin encroached water nacelle other positions whether gas leakage.The maximum drawback of this measure is, if with valve detection, incited somebody to action
Sealed missing inspection at valve interface is caused, and removes valve, a large amount of gas leakages in inner chamber will be caused.If valve changed into unidirectionally
Valve, can no doubt realize airtight detection, still, and when the water of intrusion is deep, ambient pressure increase, check valve can be automatically turned on and put
Gas.
Underwater sealing nacelle is typically all to carry other electronic equipments and use under water, and function is complicated, integrated level
Original text, operating space are narrow and small, check that airtight nacelle is more, complicated.The airtight inspection of inflation of sealing cabin is typically scheduled at general assembly
After total tune, now, lower water checks airtight, and carrying equipment can not be removed, and the risk of airtight inspection is high, and uncontrollable factor is more,
And airtight check device poor operability is inflated, or even can not complete to inflate airtight inspection work.
Utility model content
The utility model is applied to sealed compartment for reason described above and the deficiency of prior art presence there is provided one kind
Body, the device of the small airtight inspection of inflated spatial is simple, convenient, quick, and integrated level is high, occupy little space, cost
It is low.
The technical solution of the utility model is as follows：
A kind of underwater sealing nacelle bidirectional bearing inflates airtight check device, it is characterised in that：Described underwater sealing cabin
Body bidirectional bearing, which inflates airtight check device, includes plug 1, gas-charging connection 2, valve body 3, valve inside 4, spring 5 and regulation switch 6；
The medial end of described valve body 3 is equipped with valve inside 4, spring 5 and regulation switch 6 successively from inside to outside, and valve body 3 is assemblied in close
On batten down wall 7；During inflation, described gas-charging connection 2 inserts the outboard end of valve body 3 from outside, close to valve inside 4 and pushes up and opens valve
Core 4；After the completion of inflation, described plug 1 replaces described gas-charging connection 2 and inserts the outboard end of valve body 3 from outside.
In a preferred technical scheme, described plug 1 is with being provided with the first sealing ring on the contact surface of valve body 3
8。
In a preferred technical scheme, described gas-charging connection 2 with to be provided with second on the contact surface of valve body 3 close
Seal 9.
In a preferred technical scheme, described valve inside 4 is with being provided with the 3rd sealing on the contact surface of valve body 3
Circle 10.
In a preferred technical scheme, it is close that described valve body 3 is provided with the 4th on the contact surface with sealing bulkhead 7
Seal 11.
The utility model proposes underwater sealing nacelle bidirectional bearing inflate airtight check device, including plug, inflation connect
Head, valve body, valve inside, regulation switch.During assembling, first valve inside is arranged on valve body, spring is then installed and regulation is switched,
Afterwards, valve body is arranged on the wall (housing) of sealed compartment, next assembles gas-charging connection, when joint is close to valve inside, and pushed up
When opening, nacelle is inside and outside to be connected, then the joint of external source of the gas is installed into gas-charging connection arrival end, and assembling is finished.Source of the gas is opened to open
Pass can be inflated to sealed compartment, now, and nacelle is inside and outside to be connected, the pressure gauge numerical value at source of the gas, as nacelle air pressure inside
Value.After the completion of inflation, gas-charging connection is changed into plug, block and sealing ring, whole device encroached water are carried on inflation inlet, plug
In, do not interfere with its performance yet.Sealed compartment was used after a period of time, when need to be such as measured to the atmospheric pressure value of inner chamber, will
With manometric gas-charging connection at inflation inlet, you can determine inner chamber atmospheric pressure value.
Underwater sealing nacelle bidirectional bearing of the present utility model inflates airtight check device, in the use condition that space is limited
Under, the function such as integrated inflation, airtight inspection, inside and outside bidirectional bearing.The utility model is simple, convenient, quick, and integrated
Degree is high, occupy little space, cost is low.Show that the utility model can reach goal of the invention and use requirement by test of many times.
