Abstract
The present invention relates to a gap automatic safety pressure regulator. Said pressure regulator includes leather cover, upper cover gas chamber, pressure-regulating gas chamber, gas inlet tube, gas outlet tube, clamping plate, pressure-regulating spring, pressure bar, control chamber and safety spring. Said invention also provides the connection mode of all the above-mentioned components and its working principle. If the gas is leaked, the gas source can be automatically cut off by means of safety pressure regulator.
Description
Affiliated technical field
The present invention relates to a kind of automatic protective pressure regulator for fuel gas.
Background technique
At present, the use popularity rate of China resident family combustion gas is more and more higher, combustion gas brings numerous simultaneously also dangerous constantly easily securities of the lives and property of people to people, now because various security incidents such as the gas leakage that the use combustion gas causes, poisoning, fire, blast are also increasing.Although on market, also occurred some security personnel's products of developing out at gas pressure regulator, governor safety at present, but these products all exist the defective that can not be ignored: what have has introduced combustion gas gas sensing electronic equipment in structure, its structure is complexity but also impracticable not only, in case do not had electricity will lose all protection functions; What have only can report to the police when the gas leakage accident takes place and can not cut off source of the gas automatically.Therefore, we can say in existing pressure governor product, the gas leakage if in a single day its inner skin lid breaks, gas leakage just can not stop voluntarily, and this has brought serious threat for security of the lives and property of people.
Summary of the invention
The general gas pressure governor can not cut off the problem of source of the gas automatically in the prior art when leaking gas in order to overcome, the invention provides a kind of automatic protective pressure regulator for fuel gas, this automatic protective pressure regulator for fuel gas simple in structure, gas leakage the time need not external force and the power supply supply can be cut off source of the gas voluntarily, and is highly sensitive, safe and reliable.
The technical solution adopted for the present invention to solve the technical problems is: comprise upper gas-covering chamber and the pressure chamber separated by the skin lid, the two ends of pressure chamber are provided with suction tude and steam outlet pipe, clamping plate are positioned in the skin lid and with skin and cover interlock, be provided with pressure adjusting spring between clamping plate and the last tegmental wall, the depression bar that the clamping plate connecting rod interlock of skin lid below is movably hinged, the capping cap of depression bar end matches with the outlet end of suction tude, breathing pipe is set in upper gas-covering chamber, breathing pipe communicates with the control room, be provided with in the control room piston and with the magnet of piston interlock, the button of pulling in magnet and the pressure chamber matches, and pulls and withholds the spring by security personnel, and the spring of ensuring public security is relative with an end of depression bar.
Breathing pipe is arranged in the tegmental wall, and the below of skin lid is provided with supporting plate.
In clamping plate, be provided with spring and position-limited lever, an end top pressure spring of position-limited lever, the other end give prominence to outside clamping plate and be arranged on " people " shape on push rod in the air valve on the tegmental wall match.
The present invention can eliminate the security incident of breaking and leaking gas and cause because of gas pressure regulator, governor skin lid, and not need any external force and power supply supply by above-mentioned specific design, has simple in structure, highly sensitive, safe and reliable advantage.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present invention is described.
Accompanying drawing is a structural representation of the present invention.
As shown in the figure, the present invention includes upper gas-covering chamber 2 and the pressure chamber 3 separated by skin lid 1, the below of skin lid 1 is provided with supporting plate 18, the two ends of pressure chamber 3 are provided with suction tude 4 and steam outlet pipe 5, clamping plate 6 are positioned in the skin lid 1 and with skin and cover 1 interlock, in clamping plate 6, be provided with spring 19 and position-limited lever 20, one end top pressure spring 19 of position-limited lever 20, the other end give prominence to outside clamping plate 6 and be arranged on " people " shape on push rod 22 in the air valve 21 on the tegmental wall 7 match, be provided with pressure adjusting spring 8 between clamping plate 6 and the last tegmental wall 7, skin covers the depression bar 10 that clamping plate connecting rod 9 interlocks of 1 below are movably hinged, the capping cap 11 of depression bar 10 ends matches with the outlet end of suction tude 4, breathing pipe 12 is set in upper gas-covering chamber 2, and this breathing pipe 12 can design in last tegmental wall 7, and breathing pipe 12 communicates with control room 13, be provided with in the control room 13 piston 14 and with the magnet 15 of piston 14 interlocks, the button 16 of pulling in magnet 15 and the pressure chamber 3 matches, and pulls button 16 and presses security personnel's spring 17, and security personnel's spring 17 is relative with an end of depression bar 10.Under user mode, automatic protective pressure regulator for fuel gas is received on the gas cylinder, open the angle valve of steel cylinder, have a large amount of combustion gas and enter pressure chamber 3 through inlet hole this moment, rubber skin lid 1 can be heaved the push rods of going up in sliding and the pushing tow air valve 21 rapidly by clamping plate 6 drive position-limited levers 20 22 rapidly makes its unlatching, allow upper gas-covering chamber's 2 interior gas and ambient airs carry out the minimum gas exchange fast, air valve 21 can be closed again automatically then, position-limited lever 20 also can continue to go up sliding, until upper gas-covering chamber's shell wall that withstands on the top and stagnation.When rubber skin lid 1 has taken place to break for a certain reason, the back combustion gas of breaking must flow into upper gas-covering chamber 2 from pressure chamber 3 continuously, because this moment, air valve 21 was in closed condition, so this moment, upper gas-covering chamber's 2 interior air pressure can become big by automobile, because control room 13 communicates through breathing pipe 12 roads with upper gas-covering chamber 2, so the air pressure in control room 13 also can become big together when the change of upper gas-covering chamber's gas 2 pressure is big, after the gas atmosphere in the control room 13 reaches a certain size, rubber seal piston 14 can be pushed the left side to by controlled room 13 interior gases, because magnet 15 is connected as a single entity with rubber seal piston 14, so magnet 15 also can be pushed to the left side simultaneously, strong magnetic force lower plate button 16 at magnet 15 can be inhaled to the right rapidly, and plate button 16 and security personnel's spring 17 are broken away from.In the moment of taking place to break away from, original security personnel's spring 17 that always is in confined state can flick and head on tightly depression bar 10 rapidly finally can make capping cap 11 tightly seal the outlet end of pushing down suction tude 4 downwards, thereby cut-out source of the gas, stop combustion gas to continue to enter pressure chamber, finally realize the function of automatic protecting through inlet hole.For fear of taking place, automatic protective pressure regulator for fuel gas in long-term using process, may bring some negative effects to the pressure regulating performance and the product itself of pressure governor because of variation such as the temperature of pressure governor outside air, air pressure, humidity, we have designed air valve 21, so that make upper gas-covering chamber 2 and the outer air of pressure governor can often carry out " gas exchange ".Even do not increase design air valve 21, just upper gas-covering chamber 2 is in closed state, at this moment still proper functioning in the same old way of automatic protective pressure regulator for fuel gas.
