Description
Technical Field
The utility model relates to a high-pressure hydrogen is thermal safety relief device for bottle.
Background
High pressure hydrogen is typically stored in puncture-resistant high pressure hydrogen cylinders, which typically include a thermal safety vent (TPRD), wherein the TPRD is in communication with the interior of the high pressure cylinder, and in an emergency (e.g., in the event of a fire), the glass bulb with air bubbles inside the TPRD is ruptured by thermal expansion of the gas, and the piston is displaced by internal pressure to open the gas vent valve to discharge the hydrogen from the hydrogen cylinder.
In the existing TPRD, hydrogen in a hydrogen cylinder cannot be directly discharged under the condition that a glass ball with air bubbles in the inner part is not broken, and only a gas outlet valve is opened to discharge the hydrogen in the hydrogen cylinder through a discharge valve in a pipeline, so that the operation is inconvenient and the cost is increased.
Disclosure of Invention
An object of the utility model is to provide a convenient operation's novel high-pressure hydrogen is hot safe discharge device of integrated form for bottle.
The technical solution of the utility model is that:
the utility model provides a novel high-pressure hydrogen is hot safe relief device of integrated form for bottle, characterized by: the thermal safety relief device is arranged in a relief device mounting groove in the cylinder valve and can move left and right along the relief device mounting groove, the front end of the thermal safety relief device is in a protruding form, the protrusion extends into a first channel communicated with the interior of a cylinder, a step plane at the rear end of the protrusion is in a surface contact sealing form with the cylinder valve, and a second channel is arranged between a step structure at the rear end of the protrusion and the relief device mounting groove; the second channel is communicated with the discharge outlet through a third channel; the bleeder valve is provided with a fourth channel communicated with the first channel and a fifth channel communicated with the second channel.
The first channel, the second channel, the third channel, the fourth channel and the fifth channel are all in a curve form.
The utility model discloses not only convenient operation and reduce cost have still reduced entire system's volume and weight.
The utility model discloses with TPRD and relief valve integrated design to hydrogen cylinder bottle valve on, the TPRD passageway adopts three bends, and the relief valve passageway adopts four bends, TPRD and relief valve sharing hydrogen escape canal, reach the operation requirement of safe quick relief. Not only convenient operation and cost reduction, but also the volume and weight of the whole system are reduced.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic flow chart of the present invention.
Fig. 2 is a sectional structural view of the present invention.
Detailed Description
A novel integrated thermal safety relief device for a high-pressure hydrogen cylinder comprises a thermal safety relief device 8 and a relief valve 5 which are arranged in a cylinder valve 1, wherein the thermal safety relief device is arranged in a relief device mounting groove in the cylinder valve and can move left and right along the relief device mounting groove, the front end of the thermal safety relief device is in a protrusion 11 form, the protrusion extends into a first channel 2 communicated with the inside of the cylinder, a step plane at the rear end of the protrusion is in a surface contact sealing form with the cylinder valve, and a second channel 9 is arranged between a step structure at the rear end of the protrusion and the relief device mounting groove; the second channel is communicated with the discharge outlet 6 through a third channel 7; the bleeder valve is provided with a fourth channel 3 communicated with the first channel 2 and a fifth channel 4 communicated with the second channel 9 respectively.
The first channel, the second channel, the third channel, the fourth channel and the fifth channel are all in a curve form.
As shown in fig. 1, hydrogen gas may flow to the vent outlet 6 through two passages, TPRD8 on the vent apparatus inlet 10 and the vent valve 5.
The TPRD channel adopts three bends (a first channel, a second channel and a third channel), the bleeder valve channel adopts four bends (a first channel, a second channel, a fourth channel and a fifth channel), and the ratio of the TPRD channel to the bleeder valve channel can be 4: 1 (the ratio of the average diameter of the first channel, the second channel and the third channel to the average diameter of the first channel, the second channel, the fourth channel and the fifth channel is 4: 1), wherein the TPRD and the relief valve share one hydrogen discharge channel to meet the use requirement of safe and rapid relief; of course, the above ratio can be adjusted according to actual conditions.
In fig. 2, TPRD8 and the relief valve 5 are integrated on the cylinder valve 1, when TRPD8 works, the high-pressure hydrogen in the cylinder pushes the thermal safety relief device to the left, the step plane at the rear end of the protrusion is separated from the cylinder valve contact surface, the high-pressure hydrogen in the cylinder flows through the first channel 2, the second channel 9 and the third channel 7 to the relief outlet 6, and in the process, the first channel 2 and the second channel 3 are in a closed state; the TRPD (8) does not work, when the system is overhauled, the first channel 2 and the second channel 3 are opened, high-pressure hydrogen in the bottle flows through the second channel 3, the third channel 4 and the fourth channel 7 through the first channel 2 to flow to the discharge port 6, and in the process, a step plane at the protruding rear end of the thermal safety discharge device and the bottle valve are in a surface contact sealing mode (the first channel and the second channel are not communicated).
