Description
Technical field
Fire-fighting domain is the utility model is related to, a kind of gas pipeline contact is especially designed and changes valve waste gas collection device.
Background technology
, can be residual toward contact inside its maintenance sites pipeline when flammable explosive gas tie-in point leakage maintenance or replacing valve
Some are stayed to put unnet residual air.If do not handled before construction totally, once blast may be produced, trigger fire by running into spark
Calamity.
Utility model content
The purpose of this utility model is to provide a kind of gas pipeline contact and changes valve waste gas collection device, passes through the present apparatus
Flammable explosive gas tie-in point, which is leaked, helpdesk or need to be changed at valve, and the collection of remaining combustion gas and clear is carried out before construction
Reason, ensure the safety progress of maintenance engineering.
To achieve the above object, the utility model is realized using following technical scheme：
A kind of gas pipeline contact changes valve waste gas collection device, including gas reservoir, conduit, vavuum pump, gas
Collecting hood；Gas reservoir connects vavuum pump by conduit, and vavuum pump connects gas collection cap by conduit.
The gas collection cap includes upper tube half, lower tube half, is flexible coupling, and connects between upper tube half and lower tube half for embedded
Connect, be fixed with and be flexible coupling at the both ends of upper tube half/lower tube half, the one end being flexible coupling is provided with VELCRO adhesive tape, and the other end, which is provided with, is
Band.
Compared with prior art, the beneficial effects of the utility model are：
A kind of gas pipeline contact changes valve waste gas collection device, by the present apparatus to flammable explosive gas tie-in point
Leakage helpdesk need to be changed at valve, and the collection and cleaning of remaining combustion gas are carried out before construction, ensures the safety of maintenance engineering
Carry out.
Brief description of the drawings
Fig. 1 is the structural representation that a kind of gas pipeline contact of the utility model changes valve waste gas collection device.
Fig. 2 is the expanded schematic diagram of gas collection cap.
Fig. 3 is the schematic diagram that gas collection cap is wrapped on service pipe.
Fig. 4 is Fig. 3 A-A direction views.
In figure：1- gas reservoirs, 2- conduits, 3- vavuum pumps, 4- service pipes, 5- gas collection caps, 5-1 upper tube halfs,
5-2 lower tube halfs, 5-3 frenulums, 5-4 are flexible coupling, 5-5 VELCROs adhesive tape, 6- valves.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings：
See Fig. 1, a kind of gas pipeline contact changes valve waste gas collection device, including gas reservoir 1, conduit 2, vacuum
Pump 3, gas collection cap 5；Gas reservoir 1 connects vavuum pump 3 by conduit 2, and vavuum pump 3 connects gas collection by conduit 2
Cover 5.
See Fig. 2, Fig. 4, the gas collection cap 5 includes upper tube half 5-1, lower tube half 5-2, be flexible coupling 5-4, upper tube half 5-1
It is connected between lower tube half 5-2 for embedded, is fixed with the 5-4 that is flexible coupling at upper tube half 5-1/ lower tube halfs 5-2 both ends, is flexible coupling
5-4 one end is provided with VELCRO adhesive tape 5-5, and the other end is provided with frenulum 5-3.VELCRO adhesive tape 5-5 primary and secondary patch is separately fixed at
Be flexible coupling 5-4 inside and outside two sides.
See Fig. 4, conduit 2 connects with upper tube half 5-1/ lower tube halfs 5-2, in upper tube half 5-1 and lower tube half 5-2 interface
On, side (upper tube half 5-1/ lower tube half 5-2) is provided with groove, opposite side (lower tube half 5-2/ upper tube half 5-1) is provided with fin, groove
With fin mutual cooperation grafting.
In use, seeing Fig. 3, upper tube half 5-1 and lower tube half 5-2 is mutually fastened in the outside of the leak of service pipe 4, so
Upper tube half 5-1 and lower tube half 5-2 end are wrapped by being flexible coupling for upper tube half 5-1 both ends afterwards, and glued by VELCRO
Band 5-5 is adhesively fixed.
The remainder for the 5-4 that is flexible coupling is wrapped on service pipe 4, then work will be wrapped in by the frenulum 5-3 of end
The 5-4 that is flexible coupling made on pipeline 4 is tightened.
In order to adapt to the pipeline of multiple diameter specification, so upper tube half 5-1's and lower tube half 5-2 is relatively large in diameter, in order to
Use is closed on various service pipes 4, upper tube half 5-1 and lower tube half 5-2 both ends pass through magic using the 5-4 parcels that are flexible coupling
Tired prick of adhesive tape 5-5 and frenulum 5-3 is pasted to fix.
Gas collection cap 5 is installed, valve 6 is opened, opening vavuum pump 3 can be by residual in service pipe 4
Residual air is extracted.Though not accomplishing to be fully sealed at the 5-4 parcels that are flexible coupling, have no effect on to the flammable explosive gas of residual
Extract and clear up.
The space that the test side of coal gas detection instrument can also be wrapped in together between upper tube half 5-1 and lower tube half 5-2
Position (will be close to leakage point), pumping, and meanwhile the content of observation flammable explosive gas, so that it is determined that gas extraction amount.
