Abstract

The invention relates to a pressure vessel valve which is simple in structure and fine in safety and reliability, can avoid opening by mistake, and is suitable for automatic locking. The pressure vessel valve comprises a valve body, a valve rod, a lock rod and a hand wheel. The valve rod comprises a conical section and a cylindrical section. The valve body comprises a first cylindrical cavity, a conical cavity and a second cylindrical cavity. The diameter of an upper port of the conical cavity is smaller than that of the second cylindrical cavity so as to form an annular platform at the bottom of the second cylindrical cavity, and a lockout groove is arranged on the annular platform. A middle lower section of a tube body of the lock rod is sleeved on a cylindrical section of the valve rod, and a pair of waist-shaped holes is radially arranged on a middle upper section of the tube body. A spring pin is arranged in a pin hole of the lock rod, and the pair of waist-shaped holes extends from two ends of the spring pin. An annular boss is arranged at the bottom of the lock rod, an annular lock pin sleeved on the tube body is arranged at the upper end of the annular boss, a pressure ring is arranged at the lower end of the spring pin, and a spring is arranged between the pressure ring and the annular lock pin. A protrusion suitable for being matched with the lockout groove is arranged on a lower end face of the annular lock pin.

Description

[0001] This application is a divisional application, the application number of the original application: 201110086790.6, the application date: 2011-04-07, and the name of the invention "Pressure Vessel Valve Suitable for Automatic Locking" technical field [0002] The invention relates to a pressure container valve suitable for automatic locking, which is suitable for metal containers of liquefied pressure gases such as liquefied petroleum gas, coal gas, dimethyl ether and natural gas. Background technique [0003] Existing pressure vessel valves include: a valve body, a tapered valve stem that is sealingly fitted in the valve body and a handwheel connected to the top of the valve stem. The side wall of the valve body is provided with an exhaust port, and the lower end of the valve stem is axial There is a vent hole, which communicates with the vent port on the side wall of the valve stem; when the vent port on the side wall of the valve stem is in the same direction as the v...
