Valve of liquefied gas cylinder

Abstract

The invention discloses a valve of a liquefied gas cylinder. The valve comprises a valve body, a driving ring sliding seat, a driving ring, a first wire spring, an insert sleeve, a connecting rod and a second wire spring, wherein a gas filling hole is formed in the side wall of the valve body; the driving ring sliding seat is fixedly connected with the valve body; the driving ring comprises a lantern ring part and an extension part, the lantern ring part sleeves the driving ring sliding seat, a raised abutting part is arranged on the outer wall of the lantern ring part, and the extension part comprises a clamping hole; one end of the first wire spring abuts against the abutting part and the other end of the first wire spring abuts against the inner wall of the valve body; the insert sleeve is fixed in the valve body and comprises a vent hole; the connecting rod is inserted in the vent hole and can move along the vent hole, and a first sealing piece and a clamping part are fixedly arranged on the connecting rod; and one end of the second wire spring abuts against the clamping part, and the other end of the second wire spring and the inner wall of the insert sleeve are fixed relatively. The valve of the liquefied gas cylinder can be matched with an electronic identity identification type liquefied gas filling gun with an electromagnet in the prior art for use, thereby avoiding the reuse of the unchecked and scrapped liquefied gas steel cylinders and simultaneously avoiding the phenomenon of non-fixed point filling of the liquefied gas steel cylinders.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a valve for a liquefied gas cylinder. Background technique [0002] In recent years, liquefied petroleum gas, as a new type of fuel, has rapidly entered thousands of households due to its convenience and cleanliness. However, there are potential safety hazards in liquefied petroleum gas cylinders filled with liquefied petroleum gas, which will endanger personal and property safety. [0003] In order to ensure the safety of users' lives and property, the filling of liquefied gas cylinders adopts a fixed-point filling method, so as to establish a complete management file for liquefied gas cylinders, so as to prevent the use of uninspected and scrapped liquefied gas cylinders. However, due to the chaotic management of liquefied gas cylinders by liquefied gas operating companies and their supply stations, it is common for liquefied gas cylinders to be filled at non-fixed locations, or...
