Abstract
The utility model discloses a flow limiting valve for a high-pressure bottle. The flow limiting valve comprises a valve body, a piston and a conduit. An air vent and a piston mounting cavity are formed in the valve body. The internal diameter of the piston mounting cavity is greater than that of the air vent. The piston is arranged in the piston mounting cavity. One end of the conduit is fixedly arranged on the end part of the piston mounting cavity. The interior of the conduit is communicated with that of the piston. The piston is provided with a side air outlet and a top air outlet. The top air outlet is communicated with the air vent. A spring is sleeved on the piston. One end of the spring is positioned on a step at a junction of the air vent and the piston mounting cavity, and the other end of the spring is positioned on the other end part of the piston. The phenomenon that as the high-pressure bottle is filled with gas, the high-pressure bottle and a bottle valve are popped out under the quick flow of a gas filling the high-pressure to injure others can be prevented.
Description
Technical field
The utility model relates to a kind of flow-limiting valve, particularly relates to a kind of bomb flow-limiting valve.
Background technique
There is no flow-limiting valve in the cylinder valve of existing bomb, broken or after other reasons caused bottle valve fracture, gas can leak in a large number when the bomb bottle valve, bomb and bottle valve all can be jumped out by gas, and be very dangerous.
The model utility content
Based on this, for the problems referred to above, the utility model proposes a kind of bomb flow-limiting valve that can prevent effectively that this type of situation from occuring and minimizing gas leaks in a large number.
the technical solution of the utility model is: a kind of bomb flow-limiting valve, comprise valve body, piston and conduit, described valve inner has vent and piston installation cavity, the internal diameter of piston installation cavity is greater than the internal diameter of described vent, described piston is installed in described piston installation cavity, and an end of described conduit is fixed in the end of described piston installation cavity, described catheter interior communicates with described internal piston, described piston is provided with sidepiece air outlet hole and top air outlet hole, described top air outlet hole communicates with described vent, described piston sleeve is provided with spring, this spring one end is positioned at the ladder that described vent and piston installation cavity have a common boundary, one end is positioned at the other end of described piston.
In embodiment, the end with vent of described valve body is provided with outside thread therein.
In embodiment, described sidepiece air outlet hole comprises four air outlet holes therein.
The beneficial effects of the utility model are: after the bomb bottle valve is broken or accidental falling cause bottle valve when fracture, gas leaks in a large number, gas top power will be with the inner tip of piston top to valve body, then the sidepiece air outlet hole around piston will be ineffective, the top air outlet hole that only has piston is delivery air on a small quantity, can prevent due to the bomb gassy, the gas rapid flow causes bomb and bottle valve to jump out and hurts other people.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated:
Embodiment:
As shown in Figure 1 and Figure 2, a kind of bomb flow-limiting valve comprises valve body 10, piston 20 and conduit 30.Described valve body 10 inside have vent and piston 20 installation cavitys, and the internal diameter of piston 20 installation cavitys is greater than the internal diameter of described vent.Described piston 20 is installed in described piston 20 installation cavitys, and an end of described conduit 30 is fixed in the end of described piston 20 installation cavitys.Described conduit 30 is inner to communicate with described piston 20 inside, and described piston 20 is provided with sidepiece air outlet hole 20a and top air outlet hole 20b, and described top air outlet hole 20b communicates with described vent.Described piston 20 is arranged with spring 40, and these spring 40 1 ends are positioned at the ladder that described vent and piston 20 installation cavitys have a common boundary, and an end is positioned at the other end of described piston 20.
In the present embodiment, the end with vent of described valve body 10 is provided with outside thread 10a.
In the present embodiment, described sidepiece air outlet hole 20a comprises four air outlet holes.
As shown in Figure 1, under normal circumstances, in the flow speed stability situation, the gas in bomb enters from the inlet hole of conduit 30 because flow speed stability at this time, during gas flow to the pressure of intermediate piston 20 elastic force less than spring 40.At this time gas is to give vent to anger from top air outlet hole 20b and these five air outlet holes of sidepiece air outlet hole 20a of piston 20, until the bottle valve air outlet hole.
As shown in Figure 2, in case of emergency, the reason such as break when the high pressure cylinder valve and cause in bomb gas a large amount of during toward the outer effusion of bottle, during gas flow to the pressure of intermediate piston 20 elastic force greater than spring 40.At this moment piston 20 is just up pushed up by the pressure of gas flow, until on piston 20, part and upper air conduit are fitted, at this moment the gas gas of going out from the air outlet hole of piston 20 intermediate portions just can't flow out from the upper air conduit.In bottle, gas can only flow out from the top air outlet hole 20b of piston 20, at this moment reaches the purpose of current limliting.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
