Problems solved by technology

[0014] In the past, the discharge valve used in the hydrogen storage container is a spring type that adjusts the pressure release amount by changing the compression force of the spring. However, due to the complicated structure of the device, it has the following disadvantages: it is extremely difficult to miniaturize to be able to Responding to the following hydrogen storage containers that are increasingly required to be miniaturized: Hand-held or portable sizes, especially cell phone fuel cell tanks or fuel cell tanks for portable power supply equipment, etc., and the construction cost cannot be reduced

Embodiment

[0040] Hereinafter, preferred embodiments of the relief valve of the present invention will be described together with the drawings.

[0041] exist figure 1 In , symbol 1 represents a container with a built-in hydrogen storage alloy (not shown), and the container 1 may be a metal having appropriate strength and toughness such as aluminum or various steels. Furthermore, the container 1 may be an engineering plastic such as nylon or a compound of plastic and metal that satisfies the strength and toughness according to the type of gas.

[0042]On the upper part of the container 1, that is, on the end surface 1a, a circular housing recess 6A is formed in plan view, and an opening is formed at the center of the bottom surface 2A of the housing recess 6A to communicate with the housing recess 6A. 2a, and a through-shaped hole 3 is formed at the center of the bottom of the concave portion 2. On the hole 3, an elastic material such as rubber is provided in the state of blocking the h...

Abstract

A safe valve function can be obtained by pressing an elastic body into a hole of a container containing a hydrogen storing alloy or the like. A relief valve comprises an elastic body (4) joined to a hole (3) of a container (1) and a retaining plate (6) for pressing the elastic body and has a structure in which when the pressure of hydrogen or the like in the container (1) rises, gas or the like is released to the outside from between an outer surface (3a) of the hole (3) and the elastic body (4) via an escape hole (5) for the gas or the like of the retaining plate (6).

Description

technical field [0001] The present invention relates to a relief valve, and to a new and improved technique for obtaining the function of a relief valve by extrusion disposing an elastomer into a hole of a container containing a hydrogen storage alloy, gas or liquid. Background technique [0002] Conventionally, a technology has been developed that utilizes a hydrogen storage alloy capable of storing hydrogen in low-pressure compression as a hydrogen source for hydrogen energy devices represented by fuel cells. Also, when the pressure of the hydrogen storage container rises, a device for releasing the pressure, which is used in other fields, is used as in the general pressure container. [0003] For example, a spring type relief valve is also designed to be used in hydrogen storage containers. The spring type relief valve adjusts the pressure release amount by changing the compression force on the spring. [0004] In addition, in Patent Document 1 and Patent Document 2, who...
