Abstract
The invention provides an angle valve and a steel bottle. The angle valve comprises a hand wheel assembly, a valve rod, sealing devices, a locking nut, a valve, a valve rod and valve connection mechanism, a valve body and a limiting ring. The valve is installed in a valve cavity of the valve body. The valve rod and valve connection mechanism connects the valve rod with the valve and transmits torque. The upper end of the valve rod penetrates the locking nut matched with an opening end of an upper cavity body of the valve cavity of the valve body and then extends out. The sealing devices are arranged between the locking nut and the valve rod and between the locking nut and the opening end of the upper cavity body of the valve cavity of the valve body. The hand wheel assembly is connected with the upper end of the valve rod in a threaded manner. The outer side surface of the limiting ring is in close fit with the side surface of the upper cavity body of the valve cavity of the valve body. An inner hole of the limiting ring limits the valve rod, a connection piece or the valve body adjacent to the limiting ring to penetrate the inner hole. The steel bottle comprises the angle valve. According to the angle valve and the steel bottle, the limiting ring structure in close fit with the upper cavity body of the valve cavity of the valve body is adopted, and therefore elements of the angle valve are difficult to detach in the non-damage state, an anti-filling structure of the angle valve is effectively prevented from being manually damaged, and safety of the valve is improved; and the angle valve and the steel bottle are simple in structure, high in safety and high in concealment.
