Description

Household fuel gas prevents escape protection device

Technical field

The utility model relates to a kind of coal gas and prevents escape protection device, and more particularly it is that a kind of household fuel gas or piped gas leak cut-out source of the gas and alarm protecting apparatus.

Background technology

Natural gas, liquefied petroleum gas, piped gas are as fuel most economical, cleaning, huge numbers of families have day by day popularly been entered, but because above-mentioned gas has inflammable and explosive characteristics, careless slightly during use, break, come off as rubber tube, stove fire is put out in wind, and soup overflows stove fire or the toilet bathing of going out of falling forward, even switch gas leakage, forgets situation such as close.All can cause fuel gas to leak in a large number, the personnel that cause poison, chamber breath, run into kindling material in addition burn, explosion accident.

In the existing precautionary technology, adopt the air-sensitive detector, amplify through electronics, trigger sound and light alarm, the shortcoming of this series products is only to report to the police, and when unmanned on the scene, not only wasted a large amount of energy, and can't fundamentally stop major accident generation hidden danger.

Summary of the invention

The purpose of this utility model provides a kind of household fuel gas and prevents escape protection device, and in use, fault can in time be turn-offed source of the gas and warning after leaking accidentally, thereby has controlled the generation of accident effectively and guaranteed life and property safety.If when gas-jar or piped gas had the people on the scene or unmanned on the scene in family's use, it had automatic closing function and reports to the police the generation that can thoroughly stop various accidents.

The purpose of this utility model is achieved in that a kind of household fuel gas prevents escape protection device, and it comprises decompressor 11, and air-sensitive circuit supervision device is characterized in that it also has a control actuating unit; The control actuating unit is installed in the top of decompressor, and air-sensitive circuit supervision device is connected by electromagnet 5 with the control actuating unit;

In described control actuating unit, motion bar 13 two ends are respectively and manually open handle 1 and rubber valve 7, manually open handle and are followed successively by set screw 12, spring 2, locator 3, axle sleeve 6 for 1 time and all are sleeved on the motion bar 13; Rubber valve 7 is positioned at directly over the low pressure gas outlet 14, and decompressor 11 two ends are air inlet pipe joint 10 and escape pipe joint 8; Between rubber valve 7 and motion bar 13, be caulking gum pad 9; Location hook 4 is between locator 3 and electromagnet 5, and shell is 16.

Described air-sensitive circuit supervision device is by gas-sensitive head 15, amplifier GB1, GB2, relay 20, full-bridge rectifier 21, electromagnet 5, warning musical film 18, and amplifier BG3, BG4, loudspeaker 19 are formed.

In use in order to prevent that spark from producing, described locator 3, axle sleeve 6, set screw 12 are plastic products to the utility model.

Being shaped as of rubber valve 7

Shape, good seal performance, the plane that it can sealing low pressure gas outlet 14, periphery that again can sealing low pressure gas outlet 14.

The utlity model has following advantage: 1. gas-jar and gas piping user can both use, and have guaranteed the security of the lives and property.2. after the gas leak, can in time automatically shut down total source of the gas, and report to the police and announce user's coal gas, and check reason in leakage.3. after coal gas automatically shut down, the user had got rid of fault, must enter automatically and user mode by just supplying gas after the manually-operated.4. coal gas decompression and anti-leak are also used in this device.

Description of drawings

Fig. 1 is the utility model control actuating unit structure cut-away view;

Fig. 2 is the utility model air-sensitive circuit supervision device circuit figure.

The specific embodiment

Describe performance of the present utility model in detail below in conjunction with accompanying drawing.

When gas leak, gas-sensitive head 15 resistances diminish, and the GB1 base voltage raises, promote the conducting of GB2 negative voltage, at this moment the closed conducting of normally opened contact J1, the J2 of relay 20, full-bridge rectifier 21 has voltage, delivers to electromagnet 5 after rectification, electromagnet 5 adhesives drive location hook 4, location hook 4 is separated with locator 3, and at this moment compression spring 2 opens motion bar 13 is pressed down, and promotes rubber valve 7, make low pressure gas outlet 14 closures, Gas shutoff.Thereby serious consequence and personal safety as well as the property safety after having prevented to leak.

When closing coal gas, the closed conducting of the normally opened contact J1 of relay 20, voltage is given warning musical film 18, sends chimes of doom by loudspeaker 19 through BG3, BG4 amplifier after amplifying, and prompting coal gas user coal gas is leaking, and the inspection reason is also handled.

After customer inspection and handling the gas leak fault, will manually open and draw back locator hook 4 on the handle 1, and can normally use coal gas automatically from new location.
