In the following, applicant will refer to attached drawing 1-2 and a kind of detection oil and gas pipeline of the application described above
The concrete composition of the safety device of gas leakage come introduce in detail the application it is a kind of detect oil and gas pipeline gas leakage peace
The application method of full protection device: firstly, in the initial state, the limited spring 8 is in compressive state always, described in upside
Contact-making switch 3 is in close state, and the downside contact-making switch 3 is in the open state, the connecting spring 12, the lifting bullet
Spring 24 and the compressed spring 31, which are in, draws high state, remaining spring is in normal condition, and the cam 36 is located at the lifting
The downside of plate 48, described to push wheel 72 and be in horizontality with the lever 67, the electromagnet 16 is in the open state always；
When the outlet pipe 4 between the two pieces of fixed blocks 14 in left and right is there are after leak case, at the catch bar 7 of left side
Air pressure reduce, the air pressure at the catch bar 7 of right side is constant, and the left side connecting spring 12 resets, to drive left side institute
It states catch bar 7 to move right, to drive the upside contact bar 5 to move right, so that 5 right end of contact bar be made to contact
Contact-making switch 3 described in side, to make the driving motor 42 work, to drive the drive shaft 34 to work, to drive institute
The rotation of cam 36 is stated, to drive the lifter plate 48 to move upwards, to drive second demarcation plate 55 and described second
Cutoff plate 51 moves upwards, so that the rotate gear 52 is driven to rotate, so that first demarcation plate 54 is driven to move downward,
To drive the pressing plate 59 to move downward, to drive first cutoff plate 60, the pressing lever 57 and the pressing
Block 56 moves downward, to make first cutoff plate 60 that the venting cavity 50 be truncated with second cutoff plate 51, when described
Lifter plate 48 during moving upwards the adjustable spring 38 drawn high, when the adjustable spring 38 elastic force be equal to it is described convex
When taking turns the frictional force between 35 and the 34 of the driving, the lifter plate 48, which moves upwards, drives the cam 36 to move right,
When the lifter plate 48 moves upward to top side, the cam 36 is located in the driving chamber 47, the driving motor 42
It works on and the cam 36 is driven to rotate；
When the first cutoff plate 60 is contacted with 50 lower end wall of venting cavity, wheel 72 is pushed described in 61 lower end of the knock-pin drive
Rotation, to drive 67 right end of lever to rotate down, to drive 67 left end of lever to rise, to drive the lift
It rises block 64 to rise, to drive the limitation bar 68 to move upwards, to make the gag lever post 27 lose limitation, to make described
Trapezoid block 25 moves right under the action of compressed spring 31, so that 25 left end of trapezoid block be made to leave the pressure stabilizing
Chamber, to make the lifting spring 24 reset, to drive the lifting plate 21 to move downward, to make first cutoff plate
The natural gas in 60 left sides enters in the pressure stabilizing cavity 22, to make air pressure and the atmospheric pressure in 60 left side of the first cutoff plate
Equal, to slow down leakage, the air pressure at the catch bar 7 of right side is reduced, so that the right side catch bar 7 be driven to transport to the right
It is dynamic, it is contacted so that the downside contact bar 5 be driven to move right with the downside contact-making switch 3, to make the driving motor
42 stop working, and the cam 36 just rotates a circle at this time, and the right side catch bar 7, which moves right, drives the connecting column 17
It is moved right with the sliding panel 18, to drive the hydraulic plate 43 to move downward, to drive the hydraulic stem 46 to the left
Movement, so that the cam 36 be driven to reset, the adjustable spring 38 is drawn high；
After the completion of leakage processing, the briquetting 46 is pulled up, to drive the pressing plate 49 to move upwards, thus band
First cutoff plate 60 is moved to move upwards with first demarcation plate 54, by the transmission of the rotate gear 52, described
Two cutoff plates 51 decline with second demarcation plate 55, to drive the lifter plate 48 to decline, to make the venting cavity 50
Again it penetrating through, the knock-pin 61 moves upwards, so that the wheel 72 that pushes is resetted, so that the lever 67 is resetted,
To make the limitation bar 68 reset, the decline of the lifter plate 48 drives the trapezoid block 25 to move downward, the compression bullet
Spring 31 is drawn high, and when the spring block 30 resets, the gag lever post 27 moves upwards under the action of electromagnet 29, and
Positioned at 68 left side of the limitation bar, 25 left end of trapezoid block drives the rising of lifting plate 21, thus drive closed plate 20 to
Upper movement, so that the natural gas in the pressure stabilizing cavity 22 is discharged, device resets.
The beneficial effects of the present invention are: present apparatus structure is simple, it is convenient to operate, the device after leakage is completed to repair, according to
It is old to utilize again, so that the practical efficiency of device is improved, and the device autostable can judge whether to reveal,
Even if to can still work in the case where nobody, to improve safety, and the device is in the defeated of truncation natural gas
After sending, stablize the air pressure leaked out, to reduce the leakage rate of natural gas and slow down the leakage speed of natural gas, to improve
Safety.
The above, the specific embodiment only invented, but invent protection scope be not limited thereto, it is any without
The change or replacement that creative work is expected are crossed, should all be covered within the protection scope of invention.Therefore, the protection scope of invention
It should be determined by the scope of protection defined in the claims.
