Automatic filling valve for vertical liquefied gas cylinder

Abstract

The present application relates to a liquefied gas cylinder, in particular to an automatic filling valve for a vertical liquefied gas cylinder, which includes a valve body, and an electronic chip for recording information on the liquefied gas cylinder is connected to the outside of the valve body. The valve body is fixedly connected with a fixed ring, and the fixed ring is fixedly connected with a vertical drainage tube. One end of the drainage tube slides along the horizontal direction and is connected with a blocking block. The blocking block is distributed symmetrically with respect to the axis of the drainage tube. A plurality of blocking blocks move along the axis toward or away from the drainage tube, and when the plurality of blocking blocks are close to each other, the drainage tube is closed, and the outside of the valve core is provided with a drive assembly. On the one hand, this application achieves the purpose of automatic filling by matching the valve with the inflatable gun, and improves the safety of the liquefied gas cylinder. On the other hand, the driving component is located outside the drainage tube, which will not hinder the flow of liquefied gas in the drainage tube. , thereby improving the filling efficiency of liquefied gas.

Description

technical field [0001] The application relates to a liquefied gas cylinder, in particular to an automatic filling valve for a vertical liquefied gas cylinder. Background technique [0002] Liquefied gas cylinders refer to steel cylinders used to store liquefied gas. When there is liquefied gas inside, the pressure is very high, and a slight mishandling may cause an explosion. It is a special equipment. The product itself is made of steel and has a certain compressive capacity. [0003] In order to ensure the safety of liquefied gas cylinders and prevent illegal companies from filling unqualified liquefied gas cylinders privately, when filling liquefied gas cylinders, they must be automatically filled with air guns at designated points of liquefied gas legal operating enterprises. Therefore, the liquefied gas cylinder needs to be installed with a valve matching the filling gun used for fixed-point filling. [0004] At present, the Chinese patent with the notification number...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that: when the above-mentioned valve is working, the wire spring is located in the drainage hole of the valve core, which has a certain hindering effect on the filling of liquefied gas, thereby reducing the efficiency of filling liquefied gas
