Abstract
The invention provides a gas safety protection device of a gas cylinder and belongs to the technical field of machinery. The problem that an existing gas leakage alarm cannot actively discharge indoor gas out of a room, namely needs people to passively close a valve, open a window and take other measures. The gas safety protection device of the gas cylinder comprises a protective sleeve arranged at the connecting position of a gas pipeline and provided with a cavity, wherein at least two connecting ports are formed in the protective sleeve, and each connecting port of the protective sleeve is of a sealing structure enabling the corresponding gas delivery part and the protective sleeve to be sealed. An exhaust hose is further connected to the protective sleeve. When the gas safety protection device is used, one end of the exhaust hose extends out of the room, and leaked gas is gathered in the protective sleeve and then is discharged out of the room. After the gas safety protection device is arranged at the connecting position of the gas pipeline, the safety of the gas pipeline during gas delivery and gas usage can be improved. The gas safety protection device has the advantages of being simple in structure and convenient to use.
Description
The present invention is invention entitled fuel safety protecting device, Application No. 201010551681.2, and the applying date is

It is combined in one.First O-ring seal 2 is supportted greatly when using；Then gas transmission part is passed through O-ring seal 2；Finally put
Opening sealing ring makes sealing ring and gas transmission part tight fit and the formation sealing of the outer wall of the inwall of sealing ring and gas transmission part.
As depicted in figs. 1 and 2, in order to point out people's gas pipeline junction to have occurred and that gas leakage phenomenon, in
It is that prompting gas cylinder 6 is connected with exhaust hose 5.Exhaust hose 5 is included adapter 1 and is connected with protective jacket 1 cavity with one end
Adapter 2 52；The other end of adapter 2 52 is connected with prompting gas cylinder 6 and port is located at the bottom of prompting gas cylinder 6, adapter 1
With the prompting intracavity inter-connection of gas cylinder 6 and port is located at the top of prompting gas cylinder 6 for one end.During use, point out to need in gas cylinder 6
Load the media such as appropriate water, oil, pass through adapter 2 52 when the combustion gas revealed and enter in prompting gas cylinder 6 and can produce in media as well
Bubble, then people can according to prompting gas cylinder 6 in medium whether create bubble and judge to have occurred and that gas leakage right
Phenomenon.According to practical situation, prompting mode can also be carried out using another way, and that is, exhaust hose 5 is provided with gas leakage
Alarm, when having combustion gas in exhaust hose 5, Fuel Gas Leak Alarm is able to detect that above- mentioned information and then prompting letter occurs
Breath.
As depicted in figs. 1 and 2, protect the company between gas cylinder 8 and gas hose 7 using this fuel safety protecting device
When meeting place, protective jacket 1 is set on the top of gas cylinder 8, and a connectivity port 1a is located at the bottom of protective jacket 1, protection
Sealed using O-ring seal 2 between set 1 and gas cylinder 8 side wall.Another connectivity port 1a is located at the side wall of protective jacket 1
On, gas hose 7 passes from connectivity port 1a, is sealed using seal receptacle 3 between gas hose 7 and protective jacket 1.Then air relief valve,
The part such as stop valve and instrument is respectively positioned in protective jacket 1, because protective jacket 1 is made using nylon material, then still can to cut
Only valve is operated.
Embodiment two
The present embodiment is essentially identical with the structure of embodiment one and principle, and different place is: as Fig. 3 and Fig. 4 institute
Show, protective jacket 1 is in strip.When protecting the junction between pipe 9 and pipe 9 using this fuel safety protecting device, protection
The two ends of set 1 are respectively sleeved on pipe 9, and pipe 9 passes from connectivity port 1a correspondingly.At one connectivity port 1a
Can be sealed using seal receptacle 3 between protective jacket 1 and pipe 9.Can between protective jacket 1 at one connectivity port 1a and pipe 9
So that using the sealing of this sealing structure, its concrete structure is: some circumferences including being fixed on inside protective jacket connectivity port are equal
The sealing strip 10 of even distribution and the fastening piece 11 being located at outside protective jacket connectivity port, this fastening piece 11 is band.This sealing is tied
Structure can make connectivity port 1a larger, facilitates the parts such as instrument, valve and joint to be arranged in protective jacket, when above-mentioned part is installed in place
Being set at protective jacket connectivity port by band afterwards and manipulating band makes connectivity port reduce until sealing strip 10 is resisted against pipe
Outer wall on, then realize the sealing at this connectivity port.
