Embodiment
A kind of pipeline gas safety self closing stop valve as depicted in figs. 1 and 2, comprise valve body 6 and the loam cake 2 that is installed in valve body 6 tops, the two ends, the left and right sides of described valve body 6 are respectively arranged with outlet passageway 9 and gas-entered passageway 5, on the described the valve body 6 and inboard that is positioned at outlet passageway 9 is provided with vent 8, be provided with valve port 17 in the described valve body 6, the top of described valve port 17 is a upper cavity 10, the below of described valve port 17 is a lower chamber 7, on the described valve body 6 and be positioned at upper cavity 10 and be provided with cylinder 1 and cylinder 2 13, described cylinder 1 and cylinder 2 13 lay respectively at the left side and the right side of valve port 17, the two ends that the top of described cylinder 1 and cylinder 2 13 is provided with spacer 11 and described spacer 11 are separately fixed on cylinder 1 and the cylinder 2 13, on the described the valve body 6 and inboard that is positioned at cylinder 1 and cylinder 2 13 is provided with annular seal groove, be provided with seal ring 14 in the described annular seal groove, the middle part of described spacer 11 is equipped with down core bar 15, the described upper end of core bar 15 down is provided with permanent magnetic alloy 15-2, the described middle part of core bar 15 down is provided with briquetting 15-1, the outer rim that the top of described spacer 11 is provided with epithelium 4 and described epithelium 4 is fixed on the inwall of valve body 6, the middle part of described epithelium 4 is equipped with the last core bar 3 coaxial with following core bar 15, and described upper end of going up core bar 3 passes from loam cake 2.
During use, when this self closing stop valve was in original state, upper cavity 10 and lower chamber 7 were isolated fully.Because last core bar 3 and spacer 11 are made of iron, following core bar 15 is an aluminum, under the magneto motive acting in conjunction of the magnetic force of spacer 11 and permanent magnetic alloy 15-2 and last core bar 3 and permanent magnetic alloy 15-2, make core bar 15 down remain on its descending bottom and the briquetting 15-1 on it be pressed on the seal ring 14 valve port 17 blocked, at this moment, upper cavity 10 and lower chamber 7 are isolated mutually, and no combustion gas is passed through in the valve body 6.When normal use, the part that last core bar 3 stretches out loam cake 2 is mentioned, thereby core bar 3 moves up in the drive, core bar 3 core bar 15 under driving under the magnetic force of permanent magnetic alloy 15-2 is up together up to being blocked up route by spacer 11 on this moment, this moment, valve port 17 was opened, and pressure gas enters lower chamber 7 from gas-entered passageway 5, enters in the upper cavity 10 from lower chamber 7 by valve port 17 again, then enter in the outlet passageway 9 from upper cavity 10 by vent 8, this state is a normal working; Incoming pressure going up in limited time when combustion gas greater than the normal operating pressure of setting, move upward under the effect of the pressure of epithelium 4 in entering into upper cavity 10, simultaneously, epithelium 4 drives goes up the magnetic force that core bar 3 breaks away from permanent magnetic alloy 15-2, at this moment, thereby following core bar 15 makes briquetting 15-1 be pressed on the seal ring 14 under the magnetic force between permanent magnetic alloy 15-2 and the spacer 11 valve port 17 is blocked, upper cavity 10 and lower chamber 7 are isolated mutually, no combustion gas is passed through in the valve body 6, and this is the high pressure sealing state.When the high pressure sealing state; when no external force is done the time spent; briquetting 15-1 is pressed on the seal ring 14; the closed state of valve port 17 can not change; this self closing stop valve can not move with the manifold pressure variation; in the time of can guaranteeing in the room nobody like this, combustion gas can not revealed, thereby reach protection user purpose of safety.After abnormal state disappears, when needing proper functioning, can will go up core bar 3 pull-ups, the operation of proceeding proper functioning gets final product.When this self closing stop valve must have certain pressure to exist, be placed on normal working manually in pipeline.When normal working, when gaseous-pressure during less than the working pressure set, such as: stop the supple of gas or steam, gaseous-pressure is unusual, gas appliance takes off pipe, pipeline breakage etc., core bar 15 was descending fast under spacer 11 made under the magnetic force of permanent magnetic alloy 15-2 with following core bar 15, thereby valve port 17 is blocked by briquetting 15-1, upper cavity 10 and lower chamber 7 are isolated, and be the low pressure closed condition this moment.
As shown in Figure 1, preferred way is, on the described the epithelium 4 and position that is positioned at its outer rim inboard is the arcuate structure 4-1 to lower recess, by design arcuate structure 4-1, by the design of this arcuate structure 4-1, epithelium 4 is driven go up has enough range abilities when core bar 3 moves up.The end that described upward core bar 3 passes loam cake 2 is provided with handle 1, can will go up core bar 3 pull-ups easily during use and come.Described gas-entered passageway 5 and outlet passageway 9 are positioned on the same horizontal axis.
As shown in Figure 2, preferred way is, the lower end surface of described briquetting 15-1 is provided with and the corresponding annular outer 15-3 of annular seal groove, can realize the sealing good to seal ring 14 by annular outer 15-3 is set, and realizes that upper cavity 10 and lower chamber 7 better isolate.The cross section of described annular outer 15-3 is a flexuose, makes annular outer 15-3 that the sealing effect of seal ring 14 is reached best like this.On the described valve body 6 and be positioned at lower chamber 7 and be provided with sleeve 16, the described lower end of core bar 15 down extend in the sleeve 16 and can move up and down in sleeve 16, realized leading role that following core bar 15 is moved up and down guaranteeing the work of this self closing stop valve safety and stability by sleeve 16.The two ends of described spacer 11 are fixed on the top of cylinder 1 and cylinder 2 13 respectively by screw 1 and screw 2 12.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
