Abstract
The utility model relates to an automatic protector for gas combustion, comprising a casing. An air inlet pipe and an air outlet pipe are arranged on the casing. The middle part of the casing is provided with a boss which protrudes towards the center. The boss divides a casing inner cavity into an upper gas chamber and a lower gas chamber. A closed interface is formed between the boss and the lower gas chamber, and a baffle plate is arranged between the interface of the upper gas chamber and the boss. A slide bar is moveably inserted into the center of the baffle plate. The upper end part of the slide bar is provided with a position pin, and the lower end part of the slide bar is provided with a covering cap which is cooperated with the closed interface by sealing. The upper end part of the slide bar is cooperated with a reset mechanism arranged at the upper part of the slide bar and positioned outside the casing. The utility model overcomes the defects of complicated structure and lower reliability of the common protector for gas combustion in the prior art. When the gas delivery leather hose (ducts) segment takes places imperceptible gas leakage, the gas source can be automatically cut at once without any external force and power supply through the above design. The utility model has the advantages of simple structure, convenient assembly, long service life, and strong reliability.
Description
Affiliated technical field
The utility model relates to a kind of automatic protecting gas fuel device.
Background technology
Because combustion gas belongs to the clean and environment-friendly energy and aboundresources, the continuous enhancing with environmental consciousness of improving constantly along with people's living standard, combustion gas uses popularity rate also more and more higher, combustion gas brings numerous simultaneously also dangerous constantly easily securities of the lives and property of people to people, now since the various security incidents of using combustion gas to take place also get more and more.Although occurred multiple combustion gas security personnel product at present on market, these products all exist the defective that can not be ignored, and some has introduced magnetic valve in structure, but its structure is too complicated, and will lose all protection functions in case have a power failure; Some has introduced superfine spring in structure, repeatedly using rear spring that " distortion " can take place, and bigger change can take place spring force, thereby influences security personnel's performance of product greatly, even loses whole protection functions.
Summary of the invention
In order to overcome the complex structure of general gas protective device in the prior art, the problem that reliability is lower, the utility model provides a kind of automatic protecting gas fuel device, this automatic protecting gas fuel device simple in structure, need not external force and power supply supply, safe and reliable.
The technical scheme that its technical problem that solves the utility model adopts is: comprise housing, on housing, be provided with air inlet pipe and escape pipe, the housing middle part is provided with to the outstanding boss in center, boss is divided into upper chamber and lower chamber with the housing inner chamber, form closed interface between boss and the lower chamber, interface portion installing baffle plate with upper chamber, the slide bar activity is plugged on the baffle plate center, the upper end of slide bar is provided with alignment pin, the bottom of slide bar is provided with the block that is sealed and matched with closed interface, and the upper end of slide bar is positioned at the outer resetting-mechanism of housing with its top and matches.
Closed interface is tapered.
Resetting-mechanism comprises release link and back-moving spring, and back-moving spring is sleeved on outside the release link, and release link is passed housing location and relative with slide bar.
The utility model is by above-mentioned specific design, can eradicate thoroughly that gas transmission leather hose (pipeline) comes off because of taking place when using combustion gas, aging cracking, the security incident of breaking etc. and to cause, and do not need any external force and power supply supply, also can cut off source of the gas immediately automatically even trickle gas leakage takes place, have the advantage of simple in structure, easy to assembly, long service life, good reliability in gas transmission leather hose (pipeline) section.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
As shown in the figure, the utility model comprises housing 1, on housing 1, be provided with air inlet pipe 2 and escape pipe 3, housing 1 middle part is provided with to the outstanding boss 4 in center, boss 4 is divided into upper chamber 5 and lower chamber 6 with housing 1 inner chamber, form closed conical interface 9 between boss 4 and the lower chamber 6, interface portion installing baffle plate 7 with upper chamber 5, slide bar 8 activities are plugged on baffle plate 7 centers, the upper end of slide bar 8 is provided with alignment pin 13, the bottom of slide bar 8 is provided with the block 10 that is sealed and matched with closed interface 9, match with the resetting-mechanism that its top is positioned at outside the housing 1 in the upper end of slide bar 8, resetting-mechanism comprises release link 11 and back-moving spring 12, and back-moving spring 12 is sleeved on outside the release link 11, and release link 11 is passed housing 1 location and relative with slide bar 8.Under normal air feed situation, block 10 is positioned on the baffle plate 7 by slide bar 8 and alignment pin 13, and air-flow can smooth and easyly enter upper chamber 5 from lower chamber 6.If because of aging cracking takes place in gas transmission leather hose (pipeline), break, the gas leakage that comes off etc. and cause, then upper chamber 5 can be because of obtaining enough gas make-up (restriction of 10 owing to block a shot of coming through 10 next doors of blocking a shot from lower chamber 6 in moment, the maximum stream flow that flows into upper chambers 5 from lower chamber 6 just also has only or is slightly larger than the required maximum stream flow of gas kitchen ranges normal combustion), being directed at upper chamber 5 air pressure die-offs, and the air pressure of lower chamber 6 does not almost have change in a flash at this, block 10 rapid risings tightly are attached on the closed conical interface 9, thereby be implemented in the automatic source of the gas that cuts off of moment, reach the automatic protecting purpose.After finding and getting rid of the gas leakage accident, think to recover again normal air feed, only with hand is down pressed release link 11 gently, the bottommost of release link 11 can withstand the top of slide bar 8, and slide bar 8 down pushed away, block 10 and closed interface 9 are broken away from, gas in the lower chamber 6 can enter upper chamber 5 rapidly, make the upper chamber 5 and the gas pressure of lower chamber 6 reach balance again, block 10, slide bar 8 and alignment pin 13 fall to being positioned at again on the baffle plate 7 once more, again recover normal air feed, realize automatic, efficient, reliable protection function.
