Problems solved by technology

[0002] With the application and popularization of LNG facilities, there are more and more urban LNG buses, taxis, short-distance passenger vehicles, and transport vehicles. Different liquid filling vehicles have different heights from the filling port to the ground. The weight of the filling gun is generally heavy. When the distance between the filling port of the filling truck and the ground is high, the heavy filling gun will often increase the work intensity of the filling personnel. At the same time, the filling gun is heavy. Among them, there are many mechanical parts for adding liquid, which will easily lead to aggravated wear of each part, leakage, or even unusable

Abstract

The invention provides an air pressurization type sealing quick insertion gun head. The air pressurization type sealing quick insertion gun head comprises insertion gun nozzle grooves, sealing gasketinner chambers, fixed rods, tension springs, polytetrafluoroethylene sealing balls, buffer springs, connecting rods, buffer plates and protective pads, the insertion gun nozzle grooves are symmetrically arranged in the left side and the right side of an insertion gun seat, the sealing gasket inner chambers are arranged at the left sides of the insertion gun nozzle grooves, the tension springs arearranged at the internal right sides of the sealing gasket inner chambers, the polytetrafluoroethylene sealing balls are arranged on the left end surfaces of the tension springs, and the above designsolves the problem of incomplete sealing storage of an original liquid charging gun. The fixed rods are arranged at the left side and the right side of the rear end surface of the liquid charging gun,the buffer springs are mounted at the internal rear sides of the fixed rods, the connecting rods are mounted on the front end surfaces of the buffer springs, the buffer plates are mounted on the front end surfaces of the connecting rods, and the protective pads are arranged on the front end surfaces of the buffer plates, and the above design solves the problem of very easy wearing of the originalliquid charging gun. The air pressurization type sealing quick insertion gun head has the advantages of reasonable structure, safety in use, wearing avoiding and good sealing effect.

Description

technical field [0001] The invention relates to an air-pressurized sealed quick-insertion gun head, which belongs to the field of mechanical automation. Background technique [0002] With the application and popularization of LNG facilities, there are more and more urban LNG buses, taxis, short-distance passenger vehicles, and transport vehicles. Different liquid filling vehicles have different heights from the filling port to the ground. The weight of the filling gun is generally heavy. When the distance between the filling port of the filling truck and the ground is high, the heavy filling gun will often increase the work intensity of the filling personnel. At the same time, the filling gun is heavy. Among them, there are many mechanical parts for adding liquid, which will easily lead to aggravated wear of each part, leakage, or even unusability. It can be seen that the prior art needs to be further improved, and there is an urgent need for an air-pressurized sealed quick...
