Liquefied gas steel cylinder and safety valve thereof

Abstract

The invention discloses a liquefied gas steel cylinder and a safety valve thereof. The safety valve comprises a valve body, an entrance and an exit are arranged on the valve body, a valve core and a valve port which is communicated with the entrance and the exit are arranged in a valve cavity; a coil and an iron core are arranged on the periphery of the valve body, and the coil and the iron core are matched with each other; the safety valve also comprises a driving part which can slide along the periphery of the valve body, the driving part is opposite to the valve core, and the driving part and the valve core can attract with each other; when power is on, the iron core adsorbs the driving part to slide along the periphery of the valve body, and the driving part drive the valve core to move towards the iron core so as to block the valve port. The safety valve can achieve cutting off an access merely through an electric control so as to achieve safety control of a pipeline simply and conveniently. In addition, through adsorption functions of the driving part and the valve core outside the valve body, the safety valve drives the valve core inside the valve cavity to move so as to block the valve port or break away from the valve port, achieves control across separated space, and guarantees good sealing property. Therefore, the safety valve can be better applicable to products with a certain leakage risk, such as the liquefied gas steel cylinder.

Description

technical field [0001] The invention relates to the technical field of valve bodies, in particular to a liquefied gas cylinder and a safety valve thereof. Background technique [0002] In daily life, dangerous media are transported in many pipelines, such as the outlet pipeline of liquefied gas cylinders, natural gas pipelines, etc. Liquefied petroleum gas cylinders are still widely used in households that have not yet connected to natural gas, as well as some restaurants and open-air dining. Once this kind of pipeline leaks (such as the aging of the liquefied gas rubber hose, forgetting to close the valve after using the liquefied gas, etc.), there may be dangers such as fire and explosion, which may cause casualties and huge property losses. At present, there is no valve suitable for shutting off such pipeline leakage. [0003] In view of this, it is urgent to provide a safety valve that can easily shut off the pipeline when leakage occurs. Contents of the invention ...
