Abstract
An automatic switching device for a gas stove pipeline structurally comprises a main pipeline and a gas stove. A main control valve is arranged between the main pipeline and the gas stove, a portion of the main pipeline between the main control valve and the gas stove is divided into two branches, the two branches are combined at the end of the gas stove and communicated with the gas stove, a normally closed standby valve is arranged on one of the two branches, a normally open automatic valve is arranged on the other branch, and a timer is arranged at the position of the gas stove and connected with a controller for the automatic valve. By the aid of the automatic switching device, gas leakage accidents caused by not timely closing of the main control valve can be effectively avoided, and gas use safety is improved.
Description
Technical field
The utility model relates to a kind of gas safe protector, specifically a kind of gas burning hood pipeline recloser.
Background technology
At present, the gas burning hood that uses in people's life, open the master control valve, the stone or metal plate for standing a stove on as a precaution against fire of lighting gas burning hood can burn, and is safe when having people's normal operating to use, in case operating personnel leave between the operating period at gas burning hood, in time do not close fire, if flare is put out by water or because other reasons extinguishes, and combustion gas will be in to emit from the stone or metal plate for standing a stove on as a precaution against fire and do well always, gas leakage bring great threat can for people's life security.
Summary of the invention
The purpose of this utility model is to provide a kind of gas burning hood pipeline recloser, and this device can be avoided improving the security that combustion gas is used because in time not closing the generation of the gas leakage accident that the master control valve causes.
The technical scheme in the invention for solving the technical problem is:
Gas burning hood pipeline recloser, comprise trunk line and gas burning hood, be provided with the master control valve between trunk line and the gas burning hood, the part of described trunk line between master control valve and gas burning hood is divided into two branch roads, and two branch roads are at the gas burning hood end and be one and be communicated with gas burning hood; Article two, a branch road in the branch road is provided with normally closed service valve, and another branch road is provided with the automatic valve of often opening; Described gas burning hood place is provided with timer, and described timer is connected with the controller of automatic valve.
The beneficial effects of the utility model are: the utility model can be regularly and the steam line that can automatically cut off by automatic valve combustion gas, effectively avoids improving the security of combustion gas use because in time not closing the generation of the gas leakage accident that the master control valve causes.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 trunk line, 2 master control valves, 3 automatic valves, 4 service valves, 5 timers, 6 gas burning hoods.
The specific embodiment
As shown in Figure 1.Gas burning hood pipeline recloser, comprise trunk line 1 and gas burning hood 6, be provided with master control valve 2 between trunk line 1 and the gas burning hood 6, the part of described trunk line 1 between master control valve 2 and gas burning hood 6 is divided into two branch roads, and two branch roads are at the gas burning hood end and be one and be communicated with gas burning hood 6; Article two, a branch road in the branch road is provided with normally closed service valve 4, and another branch road is provided with the automatic valve 3 of often opening; Described gas burning hood 6 places are provided with timer 5, and described timer 5 is connected with the controller of automatic valve 3.
During use, master control valve 2 is opened and the stone or metal plate for standing a stove on as a precaution against fire of gas burning hood 6 is lighted, then set burning time at timer 5, behind the arrival setting-up time, timer 5 sends signal to the controller of automatic valve 3, the controller of automatic valve 3 sends signal, the controller of automatic valve 3 cuts out automatic valve 3, and trunk line 1 is cut off, and stops air feed, avoided improving the security that combustion gas is used because in time not closing the generation of the gas leakage accident that master control valve 2 causes.
