Problems solved by technology

The existing thimble valve cannot automatically stop the valve core on the mouth of the pressure cylinder when the ambient temperature rises, so the gas source cannot be cut off in time; when a fire occurs, if these gas cylinders are not cut off in time, it may cause disasters such as explosion

Embodiment Construction

[0031] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Such as Figure 1 to Figure 5 As shown, a thimble-type valve with temperature-sensitive fusing in this embodiment includes a valve body 1, and the valve body 1 is provided with an air inlet passage 2 for gas or liquid flow and a valve chamber 3 communicating with the air inlet passage 2, The valve body 1 is provided with a valve needle 4 that can slide in the intake passage 2 and is made of a low-melting point substance. The low-melting point substance has the characteristic that it begins to deform or melt when the temperature is higher than 100 ° C. The intake passage 2 There is a step hole 5 between the valve chamber 3, and the valve needle 4 is provided with a sealing step 6 that can cooperate with the step hole 5 in the intake passage 2 to close the intake passage 2. In this embodiment, the valve needle 4 adopts a low Made of high-density ...

Abstract

The invention discloses a temperature sensing fusing ejector pin type valve. The valve comprises a valve body. The valve body is internally provided with an air inlet channel, a valve cavity and a valve pin, wherein the air inlet channel allows air or liquid to flow and communicates with the valve cavity, and the valve pin can slide in the air inlet channel and is made from low-fusing-point matter; a stepped hole is formed between the air inlet channel and the valve cavity; and a sealing step capable of being matched with the stepped hole in the air inlet channel to close the air inlet channel is arranged on the valve pin. The valve pin is made from the low-fusing-point matter, after the valve pin is installed, when a fire occurs, the valve pin or a spring seat deforms in a temperature sensing fusing mode, a spring and the valve pin are shortened due to loss of support, the valve pin cannot normally eject open a valve core on an air source, the air source is cut off, and a bigger danger is avoided. The temperature sensing fusing ejector pin type valve is simple in structure, ingenious in design and obvious in effect, and improves the safety of the ejector pin type valve in fires.

Description

[0001] 【Technical field】 [0002] The invention relates to a thimble valve, in particular to a thimble valve with temperature sensing and fusing. [0003] 【Background technique】 [0004] Thimble valves are often used in industry and medical treatment. For example, in factories, hospitals and other places, gas cylinders containing oxygen, liquefied petroleum gas and other gases are often used. Before use, a pressure reducing valve needs to be connected. Between the pressure reducing valve and the gas cylinder There is a thimble valve connected between the ports, and the gas in the gas cylinder can be released and exported through the top of the valve needle of the thimble valve and the valve core on the gas cylinder mouth, and then the gas is transported to the place of use through the pressure reducing valve and the pipeline . Existing thimble valves cannot automatically stop the valve core on the mouth of the top pressure gas cylinder when the ambient temperature rises, so th...
