Description
The utility model relates to a kind of closer, particularly a kind of liquified petroleum gas cylinder safety shutoff that catches fire.
LP gas cylinder as is installed improper or is pressed valve gas leakage etc. in use, all can cause fire, and the people's lives and property is caused damage.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and when a kind of meeting accident is provided, the liquified petroleum gas cylinder that can the close the gas cylinder angle valve immediately automatically safety shutoff that catches fire.
The purpose of this utility model can reach by following measure: the utility model comprises that steel cylinder carries circle, angle valve, it is characterized in that: the closer housing is fixed on steel cylinder and carries on the circle, in the closer housing, be equipped with and close power plant automatically, switch handgrip one end is fixed on the angle valve, the other end passes the closer housing, stretches out outside it.
The purpose of this utility model can also reach by following measure: close power plant automatically and comprise inflammable line, drive handle, spring, inflammable line fixed bolt, spring fixed bolt, one end of spring is fixed on the spring fixed bolt, the other end and drive are joining, the other end and the inflammable line that drive handle join, the other end of inflammable line lays out the outside of closer housing and is fixed on the inflammable line fixed bolt, drives being passed by the switch handgrip.On the closer housing, also be carved with and start scale.
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a worm's eye view of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
Adopt according to Fig. 1, Fig. 2, the utility model is carried circle 1, angle valve 2, movable fixing female 3, shell set screw 4, housing 5, switch handgrip 7, is closed power plant etc. automatically and form by steel cylinder.Automatically close that power plant comprise inflammable line 6, drive 8, spring 9, inflammable line fixed bolt 10, spring fixed bolt 11 etc.Closer housing 5 is fixed on steel cylinder by the shell retaining screw and carries on the circle 1; Spring fixed bolt 11 is housed in housing 5, one end of spring 9 is fixed on the spring fixed bolt 11, and the other end joins 8 with drive, and the other end and the inflammable line 6 that drive 8 join, the other end of inflammable line 6 lays out the outside of housing 5, and is fixed on the inflammable line fixed bolt 10; Switch handgrip 7 one ends are fixed on the angle valve 2, and the other end passes housing 5 and drives 8, stretches out outside it.The position corresponding with switch handgrip 7 is carved with and started scale on housing 5.
When using at ordinary times, can shift switch handgrip 7 on the position that opens or closes onto easily, but also can determine the position of switch handgrip 7, thereby open or close angle valve 2 according to scale.Just in case when catching fire, fire can be met inflammable line 6(and make with nylon), it is blown, under the effect of spring 9, can switch handgrip 7 be retracted the position of pass to 8 by driving, thereby cut off source of the gas.
The utility model has following advantage compared to existing technology:
1. when catching fire when meeting accident, the source of the gas of autoshutdown gas cylinder plays the safeguard protection effect immediately.
2. simple and reasonable, reliable in action, easy to use, be fit to vast family and use.
