Description
The utility model relates to a kind of safety installations that uses pipeline gas fuel furnace or kitchen range that is disposed at, especially a kind of domestic gas automatic-closing valve of stopping the supple of gas or steam.
Along with the pipeline combustion gas in the city, industrial and mining enterprise universal day by day, bring great convenience to huge numbers of families, but because stop the supple of gas or steam, casualties that leakage etc. causes or the accident such as fire that causes also happen occasionally.As the water gas plant station of industrial enterprise's construction, because of having a power failure, cut off the water and reason such as equipment imperfection, regular meeting causes and stops the supple of gas or steam, and misfires behind user's opening conduits valve, if forget and shut pipeline valve, will cause accident to leak the coal gas when coming gas.Notification number is the utility model patent of CN2166341Y; provided a kind of " family expenses combustion gas stop the supple of gas or steam automatic protector "; mainly comprise the air supply valve device; also comprise by suction tude; steam outlet pipe; the air-pressure chamber that eardrum forms; eardrum and the dowel bar that connects together with eardrum; this kind automatic protector; utilize the air pressure energy of combustion gas itself to finish whole automatic protection; have certain effect, but its eardrum controls by a spring, spring extends the longest when stopping the supple of gas or steam; the pressure minimum; influence gas sealing, make safety; reliability reduces, and also relatively complicated on this model utility structure.
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and provides a kind of safety reliability good, the more simple home pipeline combustion gas of the structure automatic-closing valve of stopping the supple of gas or steam.
The purpose of this utility model is achieved through the following technical solutions, this home pipeline combustion gas is stopped the supple of gas or steam automatic-closing valve by valve body, the pressure leather cup, iron plate, ring magnet, pull bar and rubber seal are formed, valve body is the cylindrical cavity body, its top center is provided with through hole and step surface, the bottom is provided with the combustion gas inlet hole and communicates with the valve body inner chamber respectively with the combustion gas air outlet hole, ring magnet is fixedly installed on the valve body intracavity bottom, its center hole communicates with inlet hole on the valve body, the pressure leather cup is arranged on the middle part of valve body inner chamber, the valve body inner chamber is separated into, following two-part, pull bar is located in the valve body and is passed valve body top through hole, its bottom is provided with step surface and recess, the recess embedding energy covers the rubber seal of inlet hole, and iron plate is arranged on the below of pressure leather cup, fixedly links with pull bar and pressure leather cup.
For further realizing the purpose of this utility model, can also on described iron plate, add a leakproof rubber seal in the place of corresponding valve body air outlet hole, a spring and pellet shot from a slingshot are installed in perforate on valve body top center through hole side in addition, and on pull bar the corresponding position establish one with the corresponding pellet shot from a slingshot bayonet socket of pellet shot from a slingshot.
The home pipeline combustion gas of the present utility model automatic-closing valve of stopping the supple of gas or steam, when stopping the supple of gas or steam since ring magnet to the attraction of iron plate, iron plate drive pull bar and pressure leather cup are fallen, the rubber seal of pull bar bottom tightly seals inlet hole, this moment magnet suction maximum, when coming gas, though inlet hole pressure is very big, but because of the inlet hole area is very little, the power of generation still can't be backed down rubber seal, has only the pull bar pull-up, pressure leather cup and iron plate are lifted, inlet hole communicates with air outlet hole in the valve body, thus the time iron plate and ring magnet apart farthest, the suction minimum, and pressure leather cup and iron plate lifting surface area are much larger than the inlet hole area, its upward pressure that bears is just much larger than the downward suction of magnet, so even pipeline gas air pressure is very low, as long as gas is arranged, iron plate and pull bar just can not fall, guaranteed that gas circuit is unimpeded, made to the utlity model has safety, good reliability, characteristic of simple structure.
The Figure of description drawing is described as follows:
Fig. 1 is the home pipeline combustion gas automatic-closing valve overall structure schematic representation of stopping the supple of gas or steam.
View when Fig. 2 mentions for pull bar.
Fig. 3 on the iron plate with the valve body air outlet hole corresponding position Lou rubber seal schematic representation of setting up defences.
Fig. 4 establishes pellet shot from a slingshot, spring schematic representation for establishing on the pull bar on pellet shot from a slingshot bayonet socket and the valve body.
Below in conjunction with Figure of description in detail specific embodiments of the present utility model is described in detail.As shown in Figure 1, this home pipeline combustion gas is stopped the supple of gas or steam automatic-closing valve by valve body (1), pressure leather cup (2), iron plate (3), ring magnet (5), rubber seal (7), and pull bar (8) is formed, valve body (1) is the cylindrical cavity body, its top center is provided with through hole and step surface, the bottom is provided with combustion gas inlet hole (6) and communicates with valve body (1) inner chamber respectively with combustion gas air outlet hole (4), ring magnet (5) is fixedly installed on valve body (1) intracavity bottom, its center hole communicates with inlet hole on the valve body (1), pressure leather cup (2) is arranged on the middle part of valve body (1) inner chamber, valve body (1) inner chamber is separated into, following two-part, during actual fabrication, valve body (1) can be by last, following two halves are separately made, unite two into one again, pull bar (8) is arranged in the valve body (1) and passes valve body (1) top center through hole, its bottom is provided with step surface and recess, step surface is corresponding with the step surface at valve body (1) top, recess is embedded in the rubber seal (7) that can cover inlet hole (6), iron plate (3) is arranged on the below of pressure leather cup (2), fixedly link with pressure leather cup (2) and pull bar (8), in the utility model, as shown in Figure 3, can also upward a leakproof rubber seal (9) be set the place of corresponding valve body (1) air outlet hole (4) at iron plate (3).In addition as shown in Figure 4, at valve body (1) but on the top center through hole side perforate pellet shot from a slingshot (11) and spring (12) are installed, offer one and the corresponding pellet shot from a slingshot bayonet socket of pellet shot from a slingshot (11) (10) and go up the corresponding position, make the pellet shot from a slingshot card play further lock function pull bar (8) at pull bar (8).
The utility model working principle is as follows; When pipeline gas is stopped the supple of gas or steam, pressure leather cup (2), iron plate (3) and pull bar (8) fall rapidly under gravity and ring magnet (5) suction, rubber seal (7) is closed tightly with inlet hole (6), cut off gas circuit, pellet shot from a slingshot (11) snaps in bayonet socket (10) at this moment again, pull bar (8) is played further lock function, when pipeline comes gas, although inlet hole (6) pressure is bigger, but because of its area less, make upwards thrust that combustion gas produces much smaller than ring magnet (7) to iron plate (3), the downward suction of pressure leather cup (2) and pull bar (8) assembly parts, leakproof rubber seal (9) has been blocked any possible gas leakage again.When the user need use pipeline gas, as long as firmly upwards mention pull bar (8), take up pressure leather cup (2), iron plate (3) and rubber seal (7) assembly parts, combustion gas inlet hole (6) is communicated with air outlet hole (4), as shown in Figure 2, therefore iron plate (3) and ring magnet (7) are apart farthest the time, the suction minimum, and pressure leather cup (2) lifting surface area is much larger than the area of inlet hole (6), its upward pressure that bears is just much larger than the downward suction of ring magnet (7), so only otherwise stop the supple of gas or steam, pull bar (8) just can not fall, and keeps the unimpeded state of gas circuit.
