The utility model has the advantages of simple structure, convenient use and high safety and practicality. Under the emergency condition, when the environment temperature reaches the set value, the utility model can close the steel cylinder.
Description
The utility model relates to the cylinder for liquefied gas self closing device on a kind of cylinder for liquefied gas air valve or similar coal gas, natural gas air valve or other valve.
Cylinder for liquefied gas is the container that China is used to adorn liquefied gas, this type of container, and it closes or opens all that the very important person turns round, in case meet accident, gas cylinder can not in time be closed, and major accident will take place.
The purpose of this utility model just provides a kind of can being installed on the gas tank, when temperature arrives design temperature, can close the cylinder for liquefied gas self closing device of gas check valve automatically.
Solution of the present utility model is such: have the gear that is connected with valve core of steel cylinder, the gear that is meshed with gear is the power output gear of temperature control clockwork spring control device.Utilize temperature controller control clockwork to rotate, the power of rotation outputs to the gear on the valve core of steel cylinder, drives valve core of steel cylinder and rotates, and closes gas cylinder.
The utility model has the advantages that simple in structure, easy to use, safe and practical, can be in case of emergency, when environment temperature reaches setting value, close gas cylinder.
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is first kind of structural representation of the present utility model.
Accompanying drawing 2 is accompanying drawing 1 vertical views when taking off lid 21.
Accompanying drawing 3 is structural representations of structure temperature controller shown in the accompanying drawing 1.
Accompanying drawing 4 is second kind of structural representation of the present utility model.
Accompanying drawing 5 is accompanying drawing 4 structural representations when taking off lid 21.
Accompanying drawing 6 is structural representations of structure temperature controller shown in the accompanying drawing 4.
The utility model includes: gas cylinder knob 1, nut 2, spool 3, air valve nut 4, gear (5,6,8,9,14,15,17), axle (7,10,18,20,27), temperature controller 11, clockwork spring 12, base plate 13, ratchet 16, knob 19, lid 21, fixation clip 22, latch 23, spring 24, fork 25, centering block 26, pin 28, ratchet 29, temperature control sheet 30, test handle 31.
The utlity model has the gear 5 that is connected with valve core of steel cylinder 3, the gear 6 that is meshed with gear 5 is power output gears of temperature control clockwork spring control device.Described temperature control clockwork spring control device has temperature controller 11, the motion that the retaining mechanism on the temperature control sheet 30 of temperature controller 11 can pin temperature control clockwork spring control device.Described retaining mechanism is to have with temperature control sheet 30 to join and the centering block 26 of accompany movement, and centering block 26 pins clockworks, and when moving to desired location, centering block 26 discharges clockworks and breaks away from.Concrete structure is that the fork 25 on the centering block 26 joined with latch 23 in when locking, is following temperature control sheet 30 when moving to desired location, fork 25 and latch 23 disengagings.
For not influencing manual unlocking or close gas check valve, in the clockwork described in the present embodiment, the gear shaft 10 that to have its installation axle hole be long arc shape, two gears are thrown off at ordinary times under the effect of spring 24.
In the embodiment shown in Figure 1, described gear 5 is to be connected as a single entity with gas cylinder knob 1, is installed on the valve core of steel cylinder 3.Clockwork spring 12 is arranged on sidepiece, the disk 30 of temperature controller is shaped as recessed under the normal temperature state, when environment temperature makes this thin slice temperature be elevated to the warning temperature of manufacturing setting, thin slice sharply is deformed into epirelief, thereby impeller-hub 27, be fixed in the fork 25 of axle on 27 and break away from latch 23, the rotation that centering block 26 can't limiting gear 27.
Present embodiment is to adopt fixation clip 22 to be fixed on the air valve nut 4, thereby this device is fixed on the steel cylinder.
In the embodiment shown in Figure 4, described gear 5 is to be connected with valve core of steel cylinder 3, and clockwork spring 12 is arranged on the middle and lower part, and volume is reduced.The disk 30 of temperature controller is shaped as the plane under the normal temperature state.When environment temperature made this thin slice temperature be increased to the warning temperature of manufacturing setting, thin slice sharply was deformed into recessed.Thereby impeller-hub 27 is fixed in the fork 25 of axle on 27 and breaks away from latch 23, the rotation that centering block 26 can't limiting gear 17.
Operation principle of the present utility model is:
When twist knob 19 counterclockwise with hand axle 18 is rotated, gear 15 on the axle 18 and gear 14 engagements, axle 20 clockwise rotates, and clockwork spring 12 tightens, and has ratchet 16 and ratchet 29 to prevent clockwork spring Hui Song on the axle 18.Ratchet is fixed on the gear 17.Gear 17 skies are enclosed within on the axle 18, but are rotated by centering block 26, fork 25 and latch 23 restrictions.Because the axis hole of axle 10 is a long arc shape, at this moment, gear 9 is thrown off with gear 8 owing to be subjected to the effect of spring 24.Therefore not interrupted when rotation air valve knob 1 opens or closes Steel cylinder gas valve.
The disk 30 that has bimetal leaf to make in the temperature controller 11 in the structure shown in the accompanying drawing 1, is shaped as recessed under the normal temperature state.When environment temperature made this thin slice temperature be increased to the warning temperature (as 60 degree) of manufacturing setting, thin slice sharply was deformed into epirelief.Thereby impeller-hub 27 is fixed in the fork 25 of axle on 27 and breaks away from latch 23, the rotation that centering block 26 can't limiting gear 17.In the structure shown in the accompanying drawing 4, the disk 30 of temperature controller is shaped as the plane under the normal temperature state.When environment temperature made this thin slice temperature be increased to the warning temperature of manufacturing setting, thin slice sharply was deformed into recessed.Thereby impeller-hub 27 is fixed in the fork 25 of axle on 27 and breaks away from latch 23, the rotation that centering block 26 can't limiting gear 17.At elastic force effect lower gear 14 turning anticlockwises of clockwork spring 12 and make gear 9 be close to gear 8 driven gears 8 to rotate.Because gear 8 and gear 6 are fixed on the same axle 7.So gear 6 also and then rotates.The gear 5 that is contained in the air valve knob bottom meshes with gear 6, thereby the air valve spool clockwise rotates and closes.
After the utility model installs, can twist knob 19 counterclockwise, tighten clockwork spring 12, upwards mention test handle 31 then, check whether this device can reliably working by gear 15,14.The cylinder for liquefied gas air valve should clockwise rotate at once and close this moment.Experiment finishes, and this handle 31 should be depressed.Twist knob 19 counterclockwise, tighten clockwork spring 12, can drop into monitoring work.For guaranteeing this device reliably working, should often so check.
Utilize the utility model also can be used for similar coal gas, natural gas air valve or other valve, meet heat and close automatically.
