Description

Valve for liquefied gas steel cylinder Technical Field The utility model relates to the technical field of valves, in particular to a valve for a liquefied gas steel cylinder. Background The liquefied gas cylinder is a refillable metal pressure vessel for storing and transporting liquefied petroleum gas, and is usually made of steel material, and has pressure resistance and sealing property, and the valve is used as a storage and release part for controlling the liquefied gas in the liquefied gas cylinder, and the performance of the valve is directly related to the use safety. However, due to the lack of a corresponding limiting structure, the valve of the existing liquefied gas steel cylinder is easy to accidentally open due to accidental collision or misoperation in the use process, and the liquefied gas in the liquefied gas steel cylinder leaks, so that serious safety accidents such as fire and explosion can be caused, and certain potential safety hazards can be caused to the property safety of personnel. Disclosure of utility model The utility model aims to provide a valve for a liquefied gas steel cylinder, which has the advantages of having a corresponding limiting structure, reducing the probability of opening the valve due to accidental collision or misoperation when the valve is not in use and improving the overall use safety. The valve for the liquefied gas steel cylinder comprises a valve main body, wherein a valve rod is arranged at the middle end of the top of the valve main body, a plunger rod is fixedly connected to the top of the valve rod, a fixed cylinder is fixedly connected to the top of the valve main body, an outer tooth ring is fixedly connected to the surface of the fixed cylinder, a pressing spring is fixedly connected to the top of the fixed cylinder, a fixed sleeve is movably connected between the upper end of the fixed cylinder and the top of the fixed disc, an inner tooth ring is fixedly connected to the lower end of an inner cavity of the fixed sleeve, the inner tooth ring is meshed with the outer tooth ring, a fixed column is fixedly connected to the top of the fixed sleeve, a hand wheel is placed at the upper end of the fixed column, an inserting hole is formed in the middle end of the fixed column, and the surface of the plunger rod is movably connected to the surface of the inserting hole.
