Abstract
The utility model discloses a bubble detection and warning device of natural gas pipeline micro leakage. The bubble detection and warning device of natural gas pipeline micro leakage aims to enable a user to detect whether gas of the pipe leaks at any time independently. Particularly, the bubble detection and warning device of natural gas pipeline micro leakage is provided with a leakage detection valve installed on a gas inlet pipe. The bubble detection and warning device of natural gas pipeline micro leakage is characterized in that a gas inlet liquid bottle and a gas outlet liquid bottle are installed at the two ends of the leakage detection valve, the gas inlet liquid bottle and the gas outlet liquid bottle are connected with each other in series through a pipeline filled with liquid, and an observation window made of transparent materials is manufactured in the gas inlet liquid bottle or the gas outlet liquid bottle. The bubble detection and warning device of natural gas pipeline micro leakage has the advantages that the user can detect whether the gas of the pipe leaks through change of the level of liquid between the two liquid bottles, the user can conduct detection at any time independently, production investment is small and the 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 that the little gas leakage bubble of a kind of natural gas line of design detects and warning device, leak gas in order to can independently detect pipeline at any time.
Specifically, the little gas leakage bubble of natural gas line detects and warning device, have be used to the leak detection valve that is installed on the admission line, it is characterized in that at leak detection valve two ends air inlet liquid bottle and the liquid bottle of giving vent to anger by the pipeline serial connection that liquid is housed, 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.
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
Figure is the utility model structural representation.
Embodiment
As shown in the figure, the little gas leakage bubble of natural gas line detects and warning device, have be used to the leak detection valve 3 that is installed on the admission line, it is characterized in that at leak detection valve 3 two ends air inlet liquid bottle 4 and the liquid bottle 5 of giving vent to anger that is connected in series by the pipeline 7 that liquid is housed being housed, and adopt transparent material to make in air inlet liquid bottle 4 or the liquid bottle 5 of giving vent to anger.Be lower than the liquid bottle 5 horizontal position the bests of giving vent to anger with air inlet liquid bottle 4 horizontal positions.In air inlet liquid bottle 4 or the liquid bottle 5 of giving vent to anger alarm 9 and alarm switch 8 are housed, alarm 9 is connected with power supply with alarm switch 8.Alarm switch 8 is the liquid level detecting switch.
Working principle: open leak detection valve 3 and air intake valve 1 earlier, after gas entered pipeline and kitchen range 6, the pressure of liquid bottle 4, liquid bottle 5 equated at this moment, and both sides liquid is in state of equilibrium (kitchen range switch 2 is in closed condition).
Need to detect when having or not gas leakage, close leak detection valve 3 earlier, when as kitchen range switch 2 and joint gas leakage being arranged, because gas leakage pressure descends, both sides form pressure difference.Air inlet liquid bottle 4 promotes liquid and descends under the effect of gas pressure, the liquid of the liquid bottle of giving vent to anger simultaneously 5 rises, and opens alarm switch 8 automatically, and alarm 9 begins to report to the police, and produces the bubble indication simultaneously.
After detecting end, open leak detection valve 3, the liquid of the liquid bottle of giving vent to anger 5 descends, and alarm switch 8 disconnects, and alarm stops to report to the police and bubble is indicated.
Claims (4)
