Description
Technical field
The utility model is related to combustion gas overcurrent automatic disconnecting devices, belong to gas safe equipment technical field.
Background technology
When gas steel pipeline back segment（That is gas steel pipeline and safety valve junction to gas kitchen ranges section）Hose aging, breakage,
Come off or bitten by muroid cause combustion gas suddenly leakage, big leakage when, be often difficult to find in time, it is easy to cause safety accident.
Utility model content
In order to overcome defect in the prior art, the purpose of this utility model is to provide a kind of simple in structure tight
It gathers, is easy for installation, suddenly leakage or when big leakage can automatically cut off the combustion gas overcurrent automatic disconnecting device of combustion gas when gas steel pipeline back segment.
To achieve these goals, the utility model uses following technical scheme：A kind of combustion gas surpasses stream automatic disconnecting device,
Including the compression bar for being arranged on pipeline upper end and being penetrated through with the pipeline, the spring being set on the compression bar and pressure cap, it is arranged on pipeline
Lower end and the fine tuning group penetrated through with pipeline, the super stream for being arranged in inner wall of the pipe and being located in the pipeline air outlet of compression bar side
Ring, is arranged in pipeline and on the pipeline air-inlet port of compression bar opposite side the super stream sealing shroud being set on the super stream ring
Strainer and positioned at it is super stream ring and strainer between ball valve.
The ball valve is aluminium ball, and the diameter of ball valve is not less than the super diameter for flowing sealing shroud.
The pipeline air-inlet port is provided with screw thread, and strainer is consolidated by being arranged on the fixation spring coil of the screw thread bottom end
It is fixed.
Compared with prior art, the utility model due to using the technology described above, has the advantages that：Knot
Structure is simple, of low cost, easy for installation, when gas steel pipeline back segment is suddenly leaked or leaked greatly, utilizes gas wink in flow process
Between pressure change generate kinetic energy, push ball valve block gas pipeline access, achieve the purpose that automatic cutting in emergency combustion gas, effectively
It avoids that gas accidents occur；, can be according to the different situations of gas source and gas kitchen ranges using fine tuning group, it can be automatic to overcurrent
The air flow value that disconnecting device automatically cuts off combustion gas is micro-adjusted, and overcurrent automatic disconnecting device is made preferably to play its effect,
Its is safe and reliable, practicability is extremely strong, and suit large area to popularize application.
Description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is retainer spring coil structures schematic diagram；
Fig. 3 is structure diagram when the utility model automatically cuts off combustion gas；
In figure：Pipeline 1, screw thread 2, pipeline air-inlet port 3, fixed spring coil 4, strainer 5, pressure cap 6, compression bar 7, sleeve 8, spring
9th, ball valve 10, super stream sealing shroud 11, pipeline air outlet 12, super stream ring 13, fine tuning group 14.
Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments：
As shown in Fig. 1~2：A kind of combustion gas surpasses stream automatic disconnecting device, including being arranged on 1 upper end of pipeline and being passed through with the pipeline
Logical compression bar 7, is arranged on 1 lower end of pipeline and is penetrated through with pipeline 1 micro- spring 9, sleeve 8 and the pressure cap 6 being set on the compression bar
Tune group 14, is set in this at the super stream ring 13 for being arranged on 1 inner wall of pipeline and being located in the pipeline air outlet 12 of 7 side of compression bar
The super super stream sealing shroud 11 flowed on ring, the strainer for being arranged in pipeline 1 and being located on the pipeline air-inlet port 3 of 7 opposite side of compression bar
5 and positioned at it is super stream ring 13 and strainer 5 between ball valve 10.Fine tuning group 14 is preferably coaxially disposed with compression bar 7.Strainer 5 has anti-
Only sundries enters in pipe the double effects for blocking air flue and preventing ball valve from sliding.Fine tuning group 14 can be to the upper bottom of ball valve 10
Carry out trace regulation is put, it, can be to overcurrent automatic disconnecting device so as to the different situations according to gas source and gas kitchen ranges
The air flow value for automatically cutting off combustion gas is micro-adjusted, and overcurrent automatic disconnecting device is made preferably to play its effect.
The ball valve 10 is aluminium ball, and the diameter of ball valve 10 is not less than the super diameter for flowing sealing shroud 11.
The pipeline air-inlet port 3 is provided with screw thread 2, and strainer 5 is carried out by being arranged on the fixation spring coil 4 of the screw thread bottom end
It is fixed.
When the normal No leakage of gas pipeline, ball valve is located at gas pipeline bottom, when gas steel pipeline back segment, that is, gas steel pipeline
Hose aging, breakage with safety valve junction to gas kitchen ranges section, coming off or being bitten by muroid leads to combustion gas suddenly leakage, big leakage
When, the increase of gas flow rate moment, the gas kinetic energy that instantaneous pressure variation generates in flow process, which lifts ball valve, blocks combustion
The access of feed channel air outlet（As shown in Figure 3）, so as to automatic cutting in emergency combustion gas.After pipeline rehabilitation, by pressure cap 6 down
Pressure, pressure cap 6 press down compression bar 7, and spring 9 is shunk, and 7 lower end of compression bar supports ball valve 10 above the fine tuning group for falling within duct bottom,
Air source is connected.
