Abstract
The invention relates to a gas device, in particular to a gas emergency cut-off valve capable of automatically cutting off gas supply under the condition of gas leakage or temperature abnormality, belonging to the gas valve manufacturing industry. The gas emergency cut-off valve comprises a valve body, a sealing pad, a valve rod, a permanent magnet, an electromagnetic coil and a return spring. Under a normal condition, the gas emergency cut-off valve can be manually opened, and under other conditions, the electromagnetic coil can be used for generating magnetic force in a mode of powering on the electromagnetic coil so as to drive an armature to downwards move and ensure that the armature is separated from the suction of the permanent magnet, and the valve is closed under the action of the return spring.
Description
Technical field:
The present invention relates to a kind of gas combustion apparatus, especially ought meet in the situation of gas leakage or temperature anomaly, can cut off voluntarily the combustion gas emergency switching-off valve of gas supply, it belongs to the manufacturing of gas valve.
Background technique:
Current along with improving constantly that city environmental protection requires, a large amount of uses of clean energy resource (liquefied petroleum gas (LPG), coal gas, rock gas), bring great convenience to the people's life.The a large amount of use of combustion gas is the performance of social progress and urban modernization, it has reduced the degree of municipal pollution widely, also bring great convenience and efficiency to people, but meanwhile also caused many disasters to society, the harm that gas leakage brings and day sharp increase simultaneously.Compared with blast that gas accidents causes with coal-fired accident, fire, more have disguise and emergentness, be more difficult for discovering thereby more dangerous, the loss that its harm consequence causes to people's lives and properties and social public security is immeasurable.In recent years for problems, many enterprises have released the warning device of some gas leakages and fire, play certain effect, but this class warning device function singleness in the market, the generation that mostly can only report to the police and can not further cut off combustion gas and then thoroughly stop accident, still leaves hidden danger.There are in recent years some imported products in reporting to the police, to close combustion gas, but eventually because price is more high-leveled and difficult to popularize.The invention provides a kind of easy for installation, use simply, can, immediately by the device of fuel gas shutoff in the time having fire occur or have gas leakage, fundamentally play the effect of protection use gas safety.
Summary of the invention:
The object of the invention is: provide a kind of easy for installation, use simple automatic gas emergency switching-off valve.As a kind of gas combustion apparatus, it on the one hand can cut off voluntarily fuel gas supply in the time there is gas leakage or temperature anomaly, thereby effectively avoids the generation of larger harm and spreading of disaster, provides safely Passive Defence for user with gas; Also can carry out active protection by user's manual opening-closing on the other hand, effectively take precautions against the potential safety hazard existing in use gas process.
To achieve the object of the present invention, the technical solution adopted for the present invention to solve the technical problems is: general cut-off valve is by valve body, valve gap and air locking composition, it is characterized in that: at valve interior wall, sealing gasket is equipped with in central authorities, valve rod and Returnning spring, the outside that valve rod leads to valve body is connected with handle, centre and valve gap connecting place at valve rod seal by O type circle, bottom at handle is peripherally equipped with armature, handle links together by bayonet lock and armature, permanent magnet is equipped with on top at armature, at the electromagnetic coil that is peripherally equipped with of permanent magnet and armature, permanent magnet and electromagnetic coil are fixed together, armature and electromagnetic coil are slidably matched, at the radome that is peripherally equipped with of electromagnetic coil, central interior in the upper end of handle is equipped with thermometer bulb, the push rod of thermometer bulb is connected with connecting rod, connecting rod links together by bayonet lock and armature.In the time that handle is outwards extracted, handle band ovable valve stem moves up together with sealing gasket, by valve opening, in the time that handle band moving armature is moved upwards up to permanent magnet together, permanent magnet holds armature, handle cannot be fallen, keep the opening state of valve, in the time that extraneous ambient temperature raises, the thermometer bulb of handle inside is heated and promotes thermometer bulb push rod and move down, thermometer bulb push rod promotes connecting rod and moves down together with armature, and armature departs from the attraction of permanent magnet, under the effect of Returnning spring, makes valve closing.In addition, in the time having other abnormal conditions to occur, can be by the mode that electromagnetic coil is switched on power, make electromagnetic coil produce magnetic force, band moving armature moves down, and makes armature depart from the attraction of permanent magnet, under the effect of Returnning spring, makes valve closing.
Permanent magnet of the present invention can be contained in the periphery of handle bottom, handle links together by bayonet lock and permanent magnet, armature is equipped with on top at permanent magnet, at the electromagnetic coil that is peripherally equipped with of permanent magnet and armature, armature and electromagnetic coil are fixed together, permanent magnet and electromagnetic coil are slidably matched, at the radome that is peripherally equipped with of electromagnetic coil.
Electromagnetic coil of the present invention can remove, bottom at handle is peripherally equipped with armature, handle links together by bayonet lock and armature, permanent magnet is equipped with on top at armature, at the radome that is peripherally equipped with of permanent magnet and armature, permanent magnet and radome are fixed together, and armature and radome are slidably matched, and this kind of mode cannot be accepted the mode throttle down by electromagnetic coil is switched on power.
Thermometer bulb in the present invention can remove, bottom at handle is peripherally equipped with armature, handle links together by bayonet lock and armature, permanent magnet is equipped with on top at armature, at the electromagnetic coil that is peripherally equipped with of permanent magnet and armature, permanent magnet and electromagnetic coil are fixed together, armature and electromagnetic coil are slidably matched, at the radome that is peripherally equipped with of electromagnetic coil, armature and radome are slidably matched, this kind of mode is by the mode throttle down that electromagnetic coil is switched on power, by manually pulling the mode Open valve of handle.
The invention has the beneficial effects as follows: on the one hand in the time there is gas leakage or temperature anomaly, can cut off voluntarily fuel gas supply, thereby effectively avoid the generation of larger harm and spreading of disaster, provide safely Passive Defence for user with gas; Also can carry out active protection by user's manual opening-closing on the other hand, effectively take precautions against the potential safety hazard existing in use gas process.
