Abstract
The utility model belongs to a natural gas pipeline slight-leakage bubble detecting device in alarm devices. The natural gas pipeline slight-leakage bubble detecting device is provided with a three-way valve which is connected with a gas inlet valve, wherein a gas inlet liquid bottle and a gas outlet liquid bottle are connected to the three-way valve in sequence, and are connected in series through a pipeline filled with liquid, an observation window which is made of transparent materials is formed in the gas inlet liquid bottle or the gas outlet liquid bottle, a gas outlet of the gas outlet liquid bottle is connected with a gas bag, the gas bag is connected with a spring, and the gas bag and the spring are together installed in a restraining frame. The natural gas pipeline slight-leakage bubble detecting device has the advantages that whether gas leakage of a pipeline happens or not can be detected according to changes of liquid levels of the two liquid bottles, a user can carry out detection at will at any time, product investment is small, and reliability is high.
Description
Technical field
The utility model belongs to the warning device technical field, particularly the gas leakage alarm device.
Background technique
Along with bottled combustion gas since particularly pipeline gas enters family and place of business, because the security incident that fuel gas pipeline leakage causes is more and more.The existing all gases detection alarm device in market all is to adopt gas sensing member to make, adopt the acoustooptic alarm mode to point out, it detects principle is that gas leaks and reaches finite concentration and just begin to report to the police, and can not report to the police for long-term micro-leakage, can cause big accident to take place for a long time like this.
In order to address this problem, the applicant discloses the novel prevention Fuel Gas Leak Alarm of a kind of multifunctional domestic in first to file, and (patent No.: 03262461.1), it is made of light actiated swicth, pressure sensitive switch, sound light alarming circuit and power supply; Draw two leads by light actiated swicth, a lead connects a contact inserting contact switch in the pressure sensitive switch behind the power supply, and another root lead directly connects another contact of contact switch in the pressure sensitive switch; Sound light alarming circuit two terminates on other two output lines of light actiated swicth.Pressure sensitive switch and light actiated swicth conspire to create a line, are connected with power supply.The structure of this employing light actiated swicth, pressure sensitive switch depends on sensitivity and the reliability of these switches, has still that cost is higher, the unsettled drawback of reliability.
For household gas range, the position of easy gas leakage is kitchen range and suction tude joint, above-mentioned warning device also is to leak the warning of generation back, whether the user can't regularly independently detect joint or pipeline and leak gas, therefore, be badly in need of wanting a kind of user can independently detect the detection alarm device of pipeline gas leakage.
The model utility content
Whether the utility model purpose is the little gas leakage bubble of a kind of natural gas line of design detection device, leak gas in order to can independently detect pipeline at any time.
Specifically, the little gas leakage bubble of natural gas line detection device, it has the three-way valve that is connected with air intake valve, and be connected with air inlet liquid bottle and the liquid bottle of giving vent to anger by the pipeline serial connection that liquid is housed on this three-way valve in turn, and adopt transparent material to make or be shaped on viewing window in air inlet liquid bottle or the liquid bottle of giving vent to anger, be connected with an air bag on the liquid bottle of giving vent to anger the simultaneously air outlet, be connected with spring on the air bag and also be contained in together in the constraint framework.
Whether the utility model advantage is to change to detect pipeline according to liquid level between two liquid bottle to leak gas, and the user can independently detect at any time, and product-specific investments is few, the reliability height.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in the figure, the little gas leakage bubble of natural gas line detection device, it has the three-way valve that is connected with air intake valve 1, and be connected with air inlet liquid bottle 4 and the liquid bottle 5 of giving vent to anger by the pipeline serial connection that liquid 8 is housed on this three-way valve in turn, and adopt transparent material to make or be shaped on viewing window in air inlet liquid bottle 4 or the liquid bottle 5 of giving vent to anger, be connected with an air bag 6 on the liquid bottle of giving vent to anger simultaneously 5 air outlets, be connected with spring 7 on the air bag 6 and also be contained in together in the constraint framework.Air inlet liquid bottle 4 horizontal positions are lower than liquid bottle 5 horizontal positions of giving vent to anger.In air inlet liquid bottle 4 or the liquid bottle 5 of giving vent to anger alarm and alarm switch are housed, alarm is connected with power supply with alarm switch.Alarm switch is the liquid level detecting switch.
Working principle: open air intake valve 1 earlier, gas by air inlet liquid bottle 4 through going out gas-liquid
Body bottle 5 enters in the air bag 6, and spring 7 rises under the effect of air pressure.
When needs detection tabs and Range switch 3 have or not gas leakage, close Range switch 3 and air intake valve 1 earlier, during if any gas leak phenomenon, the pressure in the pipeline descends, and air bag 6 is under the effect of spring 7, and gas promotes liquid 8 and produces the bubble reaction.
Claims (4)
1. detection device is steeped in the little gas leakage of natural gas line, it is characterized in that having the three-way valve that is connected with air intake valve (1), and be connected with air inlet liquid bottle (4) and the liquid bottle of giving vent to anger (5) by the pipeline serial connection that liquid (8) is housed on this three-way valve in turn, and adopt transparent material to make or be shaped on viewing window in air inlet liquid bottle (4) or the liquid bottle of giving vent to anger (5), the liquid bottle of giving vent to anger simultaneously (5) is connected with an air bag (6) on the air outlet, is connected with spring (7) on the air bag (6) and is contained in one together to retrain in the framework.
2. the little gas leakage bubble of natural gas line according to claim 1 detection device is characterized in that air inlet liquid bottle (4) horizontal position is lower than the liquid bottle of giving vent to anger (5) horizontal position.
