Abstract

The invention discloses a liquefied gas rapid mounting and dismounting connector, and belongs to the technical field of petrochemical engineering. The liquefied gas rapid mounting and dismounting connector is characterized in that a connecting pipeline is provided with a plunger, a bracket and a connecting rod linear restraining block; the connecting rod linear restraining block restrains the bracket, the plunger is connected with a connecting rod, the connecting rod is in threaded connection with a plunger driving screw through the bracket, and the plunger driving screw is connected with a first hand wheel outside of the connecting pipe through a first rotating shaft; a flow guiding sealing device is arranged in the plunger and comprises a flow guiding hole seal and a flow guiding pipe, the outer wall of the flow guiding pipe is provided with a thread, flow guiding holes are formed in the outer walls of the two ends of the flow guiding pipe, one end of the flow guiding pipe is connected with the flow guiding hole seal, and the other end of the flow guiding pipe is inserted into a sliding groove and is in threaded connection with the sliding groove; and the sliding groove is connected with a second rotating shaft through pin bolts, and the second rotating shaft penetrates through the outer wall of the connecting pipeline to be connected with a second hand wheel. The liquefied gas rapid mounting and dismounting connector is mainly used for the liquefied gas filling process, the residual fluid amount is decreased, the flow guiding sealing device is designed in the connector,opening and closing are easy, a locking rod is adopted for fixing, connection is fast and convenient, the connection reliability is improved, and the filling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to a fast loading and unloading joint for liquefied gas. Background technique [0002] With the seriousness of environmental protection, the consumption of natural gas, liquefied petroleum gas and other gaseous fuels has accelerated, and the transportation volume of natural gas, liquefied petroleum gas and other gaseous fuels has increased sharply. The inland transportation methods of liquefied gas are mainly pipeline transportation and vehicle filling transportation. Pipeline transportation is suitable for mass and fixed-point transportation. Vehicle filling transportation is flexible and convenient, and is suitable for sales network terminal transportation. [0003] Car filling transportation is a way for cars to carry liquefied gas tanks to carry liquefied gas. The transportation process involves the loading and unloading process of liquefied gas. The traditional...
