When, entire workflow is as follows：It first checks for confirming and passs the original state whether object cylinder is in no pressure, when it is in no pressure
The first knob electric-controlled switch 19 is closed when power original state, and the second knob electric-controlled switch 20 is in open state, the
Three knob electric-controlled switch 21 are closed, and after checking that confirmation is errorless, then proceed by the operation of article transmission step by step：
The first step opens the balanced valve 25 for being located at and passing and covering outside object cylinder, makes to pass and is communicated with atmospheric environment out of my cabin in object cylinder, and object is passed in confirmation
In cylinder without pressure under the premise of, pass object cylinder outer cover handle 5 by operation the outer cover 4 for passing object cylinder made to rotate displacement, eliminate
After the locking state for passing object cylinder outer cover 4, object cylinder outer cover 4 will be passed and opened；Second step, it would be desirable to which the article of transmission, which is put into, passs object cylinder sheet
In body 3, operation outer cover handle 5 makes to pass the rotation of object cylinder outer cover 4 to locked position, closes balanced valve 25；Third walks, the first rotation of rotation
Button electric-controlled switch 19 is at open state, and starts the first electric control valve 10 by the first control cable 22 and open, storage
High pressure gas in gas tank is entered by first gas pipeline 8 passs object cylinder ontology 3, implements pressurization in object cylinder ontology 3 to passing, is opening
Opening-rotary electric controling switch 20 therewith after electric rotary control switch 19 is opened, electric rotary controls switch 20 and passes through
Control cable 23 start the second electric control valve 15 be at closed state, pass at this time object cylinder ontology 3 be in be completely closed shape
State, with the continuous inflow of high pressure gas, the pressure passed in object cylinder ontology 3 is stepped up, and is passing the pressure liter in object cylinder ontology 3
When height is to close to pressure in cabin 1, rotation third knob electric-controlled switch 21, third knob electric-controlled switch 21, which passes through, controls cable
24 start third electric control valve 16, are at open state, gas will pass through the 4th gas piping 14 and second in cabin 1
Gas piping 12 is connected with object cylinder ontology 3 is passed, to reach the environmental pressure in oxygen cabin cabin 1 and pass in object cylinder ontology 3
Environmental pressure balances；4th step, opening are located at the balanced valve 26 passed on object cylinder inner cover 6, are confirming in cabin 1 and are passing object cylinder ontology
In 3 in the case of pressure complete equipilibrium, object cylinder inner cover 6 will be passed and opened, taking-up is placed on the article passed in object cylinder ontology 3 and is put into cabin
In 1, so as to complete article from the overall process transmitted out of my cabin into cabin.
The above process is the separate operations process being transmitted to article out of my cabin from oxygen cabin in cabin, such as need by cabin by article
It is transmitted to out of my cabin, principle is identical, is operated using opposite step.
The utility model key technology is to design one group of totally three knob Electronic control for carrying special arc groove
Switch, and so that three knob electric controling switch is passed through arc groove and be in engaged state, to realize three knobs
Electric controling switch is in exclusiveness linkage work state, wherein the first knob electric-controlled switch 19 be equipped with the first concave arc slot 19-1,
Second knob electric-controlled switch 20 is set there are two arc groove, is the second concave arc slot 20-1 and third concave arc slot 20-2, third respectively
Knob electric-controlled switch 21 is equipped with the 4th concave arc slot 21-1, and operation principle is as follows with design structure, refers to attached drawing 5：When passing object cylinder
When original state in not pressure, the first concave arc slot 19-1 on the first knob electric-controlled switch 19 upward, at this time with
The first electric control valve 10 being connected, be closed；Second concave arc slot 20-1 courts of the second knob electric-controlled switch 20
To the left, third concave arc slot 20-2 upward, the second motor-operated control valve 15 being connected at this time with the second knob electric-controlled switch 20
In open state；4th concave arc slot 21-1 of third knob electric-controlled switch 21 towards left, at this time with third knob is automatically controlled opens
21 connected third electric control valves 16 are closed to be closed.When pass object cylinder to realize from out of my cabin into cabin transmit article when,
It need to complete to operate according to the following steps：The first knob electric-controlled switch 19 is rotated by 90 ° to the right first, it is automatically controlled to turn the first knob at this time
The first concave arc slot 19-1 on switch 19 towards right, open by the first electric control valve 10 being attached thereto, and and then therewith will
Second knob electric-controlled switch 20 is rotated by 90 ° to the right, turns the second concave arc slot 20-1 directions on the second knob electric-controlled switch 20 at this time
Top, third concave arc slot 20-2 towards right, close, and passs in object cylinder and starts to pressurize by the second electric control valve 15 being attached thereto,
When passing the pressure in object cylinder ontology 3 and the pressure in cabin 1 is close, third knob electric-controlled switch 21 is rotated by 90 ° to the right,
The 4th concave arc slot 21-1 on third knob electric-controlled switch 21 upward, open by the third electric control valve 16 being attached thereto at this time
Open, the gas in oxygen cabin cabin 1 also pressurizes to passing object cylinder ontology 3 simultaneously, until pressure balance, when in oxygen cabin cabin 1 with
It passs to open after the pressure balance in object cylinder ontology 3 to be located at and passs balanced valve 26 on object cylinder inner cover 6 to cabin 1 and pass object cylinder sheet
Pressure in body 3 penetrate through and confirm again, then opens and passs object cylinder inner cover 6 and take out article, to complete from out of my cabin to
The needs of article are transmitted in cabin.
Because the arc on the first knob electric-controlled switch 19, the second knob electric-controlled switch 20 and third knob electric-controlled switch 21 is recessed
Slot is engaged together, is in exclusive linkage status, that is to say, that only rotate to the first knob electric-controlled switch 19
When open position, the second knob electric-controlled switch 20 can realize rotation operation；Then only in the second knob electric-controlled switch 20
Under the premise of completing rotation operation, third knob electric-controlled switch 21 can carry out rotation operation therewith, and three knobs are electronic
Control the combined operation relationship successively of switch, it is ensured that it is not in artificial maloperation to pass when object cylinder transmits article, to thorough
Bottom eliminates the risk that operating personnel are caused with personal injury.
In short, the oxygen chamber safety linkage type of the utility model pass object cylinder fundamentally solve oxygen cabin pass object cylinder transmit article
The possibility of Shi Fasheng maloperations substantially increases the safety and reliability that object cylinder is passed in oxygen cabin, is effectively protected operator
The personal safety of member, is the quantum jump that object cylinder technology is passed in oxygen cabin, has filled up domestic blank, has practical and promotion price well
Value.
