Abstract
The utility model relates to a safety pressure limiting valve used for a gas burner, which is a device automatically cutting off gas source when the gas leaks. The utility model is characterized in that the device is inside provided with an iron core, a coil curl and an armature, wherein, the armature is connected with the connecting bar of the pressure limiting valve. When the gas leaks, an alarm can carry out alarm; electric current can flow through the coil curl; electromagnetic force can be generated; the armature can be movably sucked; the connecting bar is driven to close a gas inlet. The utility model has simple structure, high reliability and convenient installation.
Description
The utility model relates to a kind of gas cooker pressure-limit valve device of the security personnel's of having effect.
The general employed pressure-limit valve of gas cooker only has the pressure limiting effect, when coal gas takes place to leak, can not close automatically, easily causes blast or fire.Also have numerous kinds of coal gas leakage alarming devices on the market, this device sends acoustooptic alarm, the timely throttle down of reminds people in the time of only working as gas leakage, to avoid fire, but when unmanned guard, even if the timely throttle down of gas leakage, still often blast fire casualty.
The purpose of this utility model is that the coal gas pressure-limit valve is necessarily transformed, and itself and coal gas leakage alarming device are organically combined, and when gas leakage, the energy automatic-closing valve cuts off source of the gas, has the pressure-limit valve device of security personnel's effect.
The purpose of this utility model is to realize like this, former pressure-limit valve upper body is connected with security personnel's valve body, two valve bodies are connected together by the hole, have the hole on the pressure-limit valve pressure adjustable cap, the connecting rod that the connection support that armature is housed passes hole and pressure-limit valve is connected together, device has coil and iron core in security personnel's valve body, has the hole on the safety valve and is convenient to coil lead is drawn.The safety valve body device has security personnel's valve gap, and iron core, coil are enclosed in the safety valve.For ease of assembling, can be on coil carrier with coil.The coal gas leakage alarming device can be as the sensor of security personnel's pressure-limit valve, and the output terminal that two of coil terminates at alarm gets final product.Safety valve covers and has the hole, can be with the light emitting diode device in the warning device on the hole.The connection support of device armature and the connecting rod of pressure-limit valve can be connected with the attaching nut, and security personnel's valve body can be made with aluminum material.For ease of regulating pressure, can have two jacks on the pressure adjustable cap 13.
Concrete structure of the present utility model can be referring to accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the electrical schematic diagram of coal gas leakage alarming device.
Among the figure, the 1st, suction tude, the 2nd, suction tude filter screen rubber ring, the 3rd, suction tude filter screen, the 4th, suction tude O-ring seal, the 5th, handwheel, the 6th, pressure-limit valve caulking gum film, the 7th, sealing film trim ring, the 8th, connecting rod, the 9th, tower spring, the 10th, nut, the 11st, spring, the 12nd, attaching nut, the 13rd, pressure adjustable cap, the 14th, coil, the 15th, coil carrier, the 16th, light emitting diode, the 17th, safety valve loam cake, the 18th, iron core, the 19th, fairlead, the 20th, armature, the 21st, security personnel's valve body, the 22nd, pressure-limit valve upper body, the 23rd, screw, the 24th, pressure-limit valve lower body, the 25th, steam outlet pipe, the 26th, valve rod, the 27th, screw, the 28th, screw rod packing ring, the 29th, valve rod rotating shaft, the 30th, inlet hole, the 31st, hole, the 32nd, hole, the 33rd, connect support, the 34th, hole, 35, the 36th, jack
When gas leakage, warning device work has electric current to flow through in the coil 14 as can be seen from Figure, produce electromagnetic force, inhale moving armature 20, because armature 20 and connecting rod 8 link together, valve rod 26 will be raised, inlet hole 30 will be closed, the while alarm equipment alarm, light emitting diode is lighted, and informs that people's coal gas has gas leakage, so that in time get rid of, and can avoid coal gas to continue to leak outside.
The utility model is to have equipped safety valve at former pressure limiting valve body, and is very easy to use because and gas leakage alarm device organically be bonded together, therefore, overcome old-fashioned alarm and only reported to the police and can not cut off the drawback of source of the gas. No matter there are people, left unguarded all can play security personnel's effect.
The utility model changes a little (gas-sensing probe, safety valve connection screw socket) and also can be applicable to the aspects such as channelization coal gas and industry (such as acetylene gas).
