Description
Technical field
The present invention relates to combustion gas overcurrent automatic disconnecting devices, belong to gas safe equipment technical field.
Background technique
When the hose aging of gas steel pipeline back segment (i.e. gas steel pipeline and safety valve junction to gas cooker section), breakage,
Fall 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.
Summary of the invention
In order to overcome defect existing in the prior art, the purpose of the present invention is to provide a kind of simple and compact for structure, peaces
Dress can automatically cut off the combustion gas overcurrent automatic disconnecting device of combustion gas conveniently, when gas steel pipeline back segment urgency leakage or big leakage.
To achieve the goals above, the invention adopts the following technical scheme: a kind of combustion gas surpasses stream automatic disconnecting device, including
Pipeline upper end is set and with the compression bar of pipeline perforation, the spring being set on the compression bar and pressure cap, setting in lower end of duct
And with pipeline perforation fine tuning group, be arranged in inner wall of the pipe and be located at compression bar side pipeline air outlet on super stream ring,
Filter on super stream sealing shroud for being set on the super stream ring, the pipeline air-inlet port for being arranged in pipeline and being located at the compression bar other side
Net and the ball valve between super stream ring and strainer.
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 the way that the fixation spring coil of the screw thread bottom end is arranged in
It is fixed.
Compared with prior art, the present invention due to using the technology described above, has the advantages that structure is simple,
Low in cost, easy for installation, when gas steel pipeline back segment is suddenly leaked or leaked greatly, using gas, instantaneous pressure becomes in flow process
Change the kinetic energy generated, pushes ball valve to block gas pipeline access, achieve the purpose that automatic cutting in emergency combustion gas, effectively avoid occurring
Gas accidents；, can be according to gas source and the different situations of gas cooker using fine tuning group, it can be to overcurrent automatic disconnecting device
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, and safety can
Lean on, practicability it is extremely strong, suit large area to popularize application.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is retainer spring coil structures schematic diagram；
Fig. 3 is the structural schematic diagram when present invention 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 9, ball
Valve 10, super stream sealing shroud 11, pipeline air outlet 12, super stream ring 13, fine tuning group 14.
Specific embodiment
The present invention is further illustrated in the following with reference to the drawings and specific embodiments:
As shown in Fig. 1~2: a kind of super stream automatic disconnecting device of combustion gas, including be arranged in 1 upper end of pipeline and with pipeline perforation
Compression bar 7, the spring 9 being set on the compression bar, sleeve 8 and pressure cap 6, the fine tuning group that 1 lower end of pipeline is set and is penetrated through with pipeline 1
14, the super stream ring 13 on 1 inner wall of pipeline and being located in the pipeline air outlet 12 of 7 side of compression bar is set, is set in the super stream
Super stream sealing shroud 11 on ring, the strainer 5 on the pipeline air-inlet port 3 for being arranged in pipeline 1 and being located at 7 other side of compression bar, with
And the ball valve 10 between super stream ring 13 and strainer 5.Fine tuning group 14 is preferably coaxially disposed with compression bar 7.Strainer 5 is miscellaneous with preventing
Object enters blocking air flue and the double effects for preventing ball valve from sliding in pipe.Fine tuning group 14 can upper and lower position to ball valve 10 into
Row trace regulation can be automatic to overcurrent automatic disconnecting device so as to according to the different situations of gas source and gas cooker
The air flow value of cutting 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 passes through the progress of fixation spring coil 4 that the screw thread bottom end is arranged in
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 cooker section, falling off or being bitten by muroid leads to combustion gas suddenly leakage, big leakage
When, gas flow rate moment increases, and the gas kinetic energy that instantaneous pressure variation generates in flow process, which lifts ball valve, blocks combustion
The access (as shown in Figure 3) of feed channel air outlet, thus automatic cutting in emergency combustion gas.After pipeline rehabilitation, down by pressure cap 6
Pressure, pressure cap 6 press down compression bar 7, and spring 9 is shunk, and ball valve 10 is supported and fallen within above the fine tuning group of duct bottom by 7 lower end of compression bar,
Gas source is connected.
