Abstract
Automatically the device of coal gas leather hose valve can be closed when the utility model discloses a kind of gas leak.When pipeline causes gas leak because of corrosion or other reason, great potential safety hazard may be formed to the person of people and property safety.Automatically can close the device of coal gas leather hose valve when the utility model provides a kind of gas leak, when gas leak, gas flowmeter can detect the leakage of coal gas automatically, automatically closes the valve in coal gas leather hose.Technical scheme is: the gas outlet of gas tank body of the present utility model is connected with pressure-reducing valve, magnetic valve side is connected with the gas outlet of pressure-reducing valve, magnetic valve opposite side is connected with gas flowmeter by leather hose, the gas flowmeter other end is connected with gas range, and gas range is provided with gas source switch.When gas leak, gas flowmeter can detect the leakage of coal gas automatically, and control system can close the magnetic valve in coal gas leather hose automatically, the potential safety hazard brought with gas leakage preventing.
Description
Technical field:
The utility model relates to a kind of safety device, specifically, automatically can close the safety device of coal gas leather hose valve when especially relating to a kind of gas leak.
Background technology:
In daily life, coal gas also also exists potential safety hazard while providing convenience for people's life.When pipeline causes gas leak because of corrosion or other reason, great potential safety hazard may be formed to the person of people and property safety.At present, lack and a kind ofly automatically can detect gas leak and automatically close the safety device of valve in coal gas leather hose.
Summary of the invention:
Automatically can close the device of coal gas leather hose valve when the purpose of this utility model is to provide a kind of gas leak, when gas leak, gas flowmeter can detect the leakage of coal gas automatically, automatically closes the valve in coal gas leather hose.
In order to achieve the above object, the technical solution of the utility model is: the device automatically closing coal gas leather hose valve during a kind of gas leak is made up of gas tank, sleeve, servomotor, pressure-reducing valve, gas flowmeter, leather hose, button, gas source switch, gas range etc.
The gas outlet of gas tank body of the present utility model is connected with pressure-reducing valve, magnetic valve side is connected with the gas outlet of pressure-reducing valve, magnetic valve opposite side is connected with gas flowmeter by leather hose, and the gas flowmeter other end is connected with gas range, and gas range is provided with gas source switch.
During use, the handle on first swivel gas tank body, makes the valve open of gas tank body, then rotary air source switch, carries out normal cooking process, does not now allow the gas flowmeter in device detect leather hose gas flow in control system.After using gas range, first reversely rotate gas source switch, make the valve closing of gas range, then reversely rotate the handle on gas tank body, make gas tank valve closing.When people are at the valve of closing gas range, but when not reversely rotating the handle on gas tank body, control system will make gas flowmeter in running order, be used for detecting the gas flow size in leather hose.When coal gas is not revealed, in leather hose, the gas flow values of gas coming through flowmeter is zero; When revealing appears in the coal gas in leather hose, when the gas flow values of gas coming through flowmeter is non-vanishing, then the buzzer installed in a device sends " drip drip " sound, and Controlling solenoid valve is closed by control system, thus close the flowing of coal gas in leather hose.Controlling solenoid valve is opened at set intervals, if when the gas flow values of gas coming through flowmeter still has numerical value in the short period of time in leather hose, then still have gas leak in leather hose, then continue shut electromagnetic valve; If when the gas flow values of gas coming through flowmeter trends towards zero in the short period of time in leather hose, then close buzzer, and make magnetic valve be in lasting open mode, in leather hose, there is no gas leak.
The beneficial effects of the utility model are: the device automatically closing coal gas leather hose valve during a kind of gas leak, when gas leak, gas flowmeter can detect the leakage of coal gas automatically, automatically controls to close the magnetic valve in leather hose, the potential safety hazard brought with gas leakage preventing.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In above-mentioned accompanying drawing, the meaning of each numbering is: 1: gas tank body; 2: pressure-reducing valve; 3: magnetic valve; 4: gas flowmeter; 5: leather hose; 6: gas range; 7: gas source switch.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1: the device automatically closing coal gas leather hose valve during a kind of gas leak, comprise gas tank body (1), pressure-reducing valve (2), magnetic valve (3), gas flowmeter (4), leather hose (5), gas range (6), gas source switch (7).
The gas outlet of gas tank body (1) of the present utility model is connected with pressure-reducing valve (2), magnetic valve (3) side is connected with the gas outlet of pressure-reducing valve (2), magnetic valve (3) opposite side is connected with gas flowmeter (4) by leather hose (5), gas flowmeter (4) other end is connected with gas range (6), and gas range (6) is provided with gas source switch (7).
During use, handle on first swivel gas tank body (1), make the valve open of gas tank body (1), then rotary air source switch (7), carry out normal cooking process, now in control system, do not allow the gas flowmeter (4) in device detect leather hose (5) gas flow.After using gas range (6), first reversely rotate gas source switch (7), make the valve closing of gas range (6), then reversely rotate the handle on gas tank body (1), make gas tank valve closing.When people are at the valve of closing gas range (6), but when not reversely rotating the handle on gas tank body (1), control system will make gas flowmeter (4) in running order, be used for detecting the gas flow size in leather hose (5).When coal gas is not revealed, in leather hose (5), the gas flow values of gas coming through flowmeter (4) is zero; When revealing appears in the coal gas in leather hose (5), when the gas flow values of gas coming through flowmeter (4) is non-vanishing, the buzzer then installed in a device sends " drip drip " sound, and Controlling solenoid valve (3) is closed by control system, thus close the flowing of coal gas in leather hose (5).Controlling solenoid valve (3) is opened at set intervals, if when the gas flow values of gas coming through flowmeter (4) still has numerical value in the short period of time in leather hose (5), then still there is gas leak in leather hose (5), then continue shut electromagnetic valve (3); If when in leather hose (5), the gas flow values of gas coming through flowmeter (4) trends towards zero in the short period of time, then close buzzer, and making magnetic valve (3) be in lasting open mode, leather hose does not have gas leak in (5).
