Abstract

PURPOSE:To shut off a gas passage in the casing of a safety valve under vibration such as an earthquake to prevent the discharge of gas, by providing a vibration-sensitive mechanism located in the gas passage and including a metal ball which can be attracted on a valve seat by a magnet. CONSTITUTION:The casing 5 of a safety valve is mounted just near a liquefied gas cylinder. A vibration-sensitive mechanism, which comprises an upper and a lower magnets 10, 12 and a metal ball 8 located in a cylindrical spacer 6 between the magnets, is provided in the center of the lower part of the casing 5 of the safety valve. Normally, gas flows into a joint 7 in the direction of an arrow in the drawing. When the safety valve casing 5 is inclined beyond a set angle by vibration or the like, the metal ball 8 is attracted on a valve seat 11 by the upper magnet 10 to stop the flow of the gas. When the joint 7 is damaged by a dropped thing or the like at the occurrence of an earthquake, the gas excessively flows temporarily so that the metal ball 8 is attracted by the upper magnet 10 to close the valve seat 11 to stop the flow of the gas.

Description

【発明の詳細な説明】 地震の虚動や、自動車事故など不慮のとき。[Detailed description of the invention] In case of unforeseen circumstances such as an earthquake or a car accident.

を誘発することが想定されている。It is assumed that if a gas cylinder falls over and a rubber hose comes off, or if a large earthquake occurs, falling objects such as roof straw may break the regulator in the high-pressure piping system, releasing raw gas and causing a large explosion due to fire. has been done.

本発明によるものを図面によって説明すれば。The present invention will be explained with reference to the drawings.

いる。At the center of the lower part of the main body 5, there are magnets 10 and 12 on the top and bottom, and a metal ball 8 is placed in a cylindrical spacer 6 in the middle.
It has a built-in "special mechanism that uses a vibration-sensing element."

平常時ガスは矢印の方向から流入しているが。Normally gas flows in from the direction of the arrow.

突然、大きな衝撃振動が加わると、直立している円筒型

斜角度（３５°以上）によって。When a large shock vibration is suddenly applied, the cylindrical cylinder that is standing upright will resonate and try to topple over due to the set tilt angle (35 degrees or more).

金属ボール８は、上部マグネット１０に吸引されて弁座
１１に吸着されるので、ガスは遮断される。Since the metal ball 8 is attracted by the upper magnet 10 and adsorbed to the valve seat 11, the gas is blocked.

The gas pressure is added and the valve seat 11 is tightened, so that the gas is shut off. In addition, this device can also respond to raw gas release accidents caused by damage to gas equipment caused by snow damage in areas with heavy snowfall.
