Abstract
Leak exhausting and explosion protection device for liquified petroleum gas steel cylinder is a kind of safety protection device of household liquified petroleum gas stove and accessory equipment, and it is to be made of the hollow tank body of sealing around and get rid of the danger passage and the air supply channel that depend on the hollow tank body.Petroleum gas steel bottle is closed in the hollow tank body.Gas leak phenomenon as in use having taken place in steel cylinder, and this device not only can send signal alarm, and can automatically burn or emission treatment to this hazardous gas, prevents that the petroleum gas that steel cylinder leaks from causing fire accident at space clustering.
Description
The present invention relates to a kind of safety protection device of household liquified petroleum gas stove and accessory equipment.
Reasons such as the liquefied petroleum ga steel cylinder in the petroleum gas stove and accessory equipment may be aging because of sealing part, and perhaps valve damages, and perhaps the local corrosion of bottle is serious, and a petroleum gas leakage phenomenon in the bottle takes place.If the ambient air stream that steel cylinder is deposited is in bad order, just the gas that leaks out can slowly be assembled, when reaching certain concentration, even a Mars can cause that all the gaseous combustion blast causes the serious consequence of loss of life and property.
In order to prevent that accident from taking place, at present people adopt the electronics automatic measuring unit of a kind of being commonly called as " Electronic Nose ", and it can be monitored automatically to airborne petroleum gas content, when airborne petroleum gas reaches certain concentration, just can send alarm signal, the caveat people take protection measure.Aforesaid electronic detecting device is though can play certain effect that prevents, the function that it self does not eliminate danger to the fire accident that gas leakage in the liquefied petroleum ga steel cylinder causes.
During gas leakage, gas is collected in the space, and this moment, whether, danger still existed regardless of the people; Even the people who is expert at has heard alarm signal,, all may cause the consequence of petroleum gas combustion explosion if handle accidentally.
Task of the present invention is to provide a kind of device that can get rid of the danger automatically, this device not only can be in liquefied petroleum ga steel cylinder gas leakage the time signal and report to the police, and can handle automatically hazardous gas simultaneously, improve the purpose of using petroleum gas stove and accessory device security thereby reach.
The present invention realizes as follows: device is made of with the passage of getting rid of the danger the hollow tank body of sealing around and the air supply channel that depends on the hollow tank body.Liquefied petroleum ga steel cylinder is sealed in hollow jar.The main effect of air supply channel is that the petroleum gas in the liquefied petroleum ga steel cylinder is drawn hollow tank body supplies with the petroleum gas stove use, and the effect of the passage of getting rid of the danger is that then the petroleum gas of liquefied petroleum ga steel cylinder leakage in hollow jar drained into outdoor automatic ignitor device carries out combustion disposal (also can directly drain into the open air).By with upper type, the fire accident of having avoided liquefied petroleum ga steel cylinder in use to cause fully because of gas leakage.
Below in conjunction with apparatus structure schematic representation that provides in the accompanying drawing and embodiment the present invention is done concrete description.
Fig. 1 is a kind of structural representation of this device.Fig. 2 is the partial schematic diagram of this structure.
With reference to Fig. 1: Mi Feng hollow tank body can be by jar (1), side's lid (2) and handle top cover (3) formation on every side.Liquefied petroleum ga steel cylinder (6) places in the hollow tank body.The top, the outside of jar (1) He Fanggai (2) respectively has a week to form the closed circuit tank that is used for retaining (4), (5) (as shown in Figure 2).Clear water is housed, in order to the side's of sealing lid (2) and handle top cover (3) and jar (1) and the square air gap that covers (2) junction in the tank.Steel cylinder output pipeline (7), bubble display unit (8) and its input pipeline (9), output pipeline (10) have constituted an air supply channel.Wherein, bubble display unit (8) aims at and is provided with the working life of improving cylinder valve.A certain amount of clear water (13) is arranged in the bubble display unit (8).One end of input pipeline (9) with imbed in the water end of output pipeline (10) and water surface maintenance certain distance.When gas passes through bubble display unit (8), will produce bubble in the water, can carry out the operation of throttle down, and avoid causing valve to damage the valve overtorquing because of psychological application by the bubble of observing in the water.In addition, an emergency cock (12) can be set also on this passage, so that cylinder valve is done emergent the use when malfunctioning.
The passage of getting rid of the danger is made of baroswitch (14), bubble display unit (15) and its input pipeline (16), output pipeline (17).One of output pipeline (17) is connected to and is installed on outdoor automatic ignitor (18).The gas of leakage in hollow tank body is arranged to automatic ignitor (18) through this passage of getting rid of the danger.If outdoor air ventilation is all right, also output pipeline (17) directly can be drawn the open air, the gas that leaks is arranged to the space.The bubble display unit of this passage (15) (the same bubble display unit of its structure (8)) aims at the air pressure in the rising input pipeline (16) and is provided with, be used for guaranteeing the reliability of baroswitch action, baroswitch (14) control alarm system (when passage connect automatic ignitor if get rid of the danger, this switch was also controlled the automatic ignitor igniting simultaneously).
When this device is done the Open valve operation: turn handle top cover (3), liquefied petroleum gas cylinder valve is opened, and petroleum gas flows to petroleum gas stove by air supply channel and uses.
During the throttle down operation: handle top cover (3) is torqued-up to till the bubble of cannot see in the bubble display unit (8).
When getting rid of the danger: the gas that leaks in hollow tank body is arranged to automatic ignitor (18) from the passage of getting rid of the danger, and the leakage pressure in the input pipeline (16) touches baroswitch (14) action; This moment, alarm buzzer sent alarm signal, automatic ignitor igniting, and the gas that drains into automatic ignitor is met the fire burns disappearance at the spout place of automatic ignitor.Passage is directly to draw the open air if get rid of the danger, and when alarm buzzer signaled, gas drained into the space and scatters and disappears from output pipeline (17).People hear alarm signal, can take measures at leisure, and the gas leakage steel cylinder is keeped in repair, handles.
