Problems solved by technology
[0003] (1) The existing liquid filling gun is manually operated, and the existing liquid filling gun itself has a large weight, and all operations require manual operation. The labor intensity of the operator is high, and the physical strength of the operator is very high;
[0004] (2) When filling continuously for a long time, the surface of the liquid filling gun is so icy that the freezing gun cannot be operated;
[0005] (3) The handle has a large rotation radius, which requires a large operating space and is extremely inconvenient to operate;
[0006] (4) The structure is relatively complicated, the production and maintenance are troublesome, and the customer's use and maintenance costs are high

Embodiment Construction
[0060] The present invention will be further described below with reference to the accompanying drawings and examples, and the embodiments of the present invention include but not limited to the following examples.
[0061] like Figure 1-11 As shown, this embodiment provides a kind of LNG program pneumatic filling gun, which mainly includes components such as a liquid filling channel, a casing, a piston, a jaw assembly, a valve assembly, etc. In this embodiment, two mutual The independent cavity drives the piston action through the switching of the air pressure in the cavity, and then drives the valve assembly and claw assembly to move, thereby realizing the push-button control of the filling and withdrawing action of the liquid filling gun, which is different from the existing ones. Compared with advanced manual liquid filling gun, the operation is simple, light and fast.
[0062] This embodiment adopts the following scheme to realize aerodynamics. There are two cavities in...

The invention discloses an LNG-form pneumatic liquid feeding gun. By means of the LNG-form pneumatic liquid adding gun, the problems that in the prior art, operation remains unchanged, and gun bodies are frozen easily are solved. The liquid feeding gun comprises a liquid feeding channel (83), a shell, a claw assembly, a valve assembly and a piston(15); the shell comprises a gun head (1), a cylinder block (11) and a cylinder cover (17); two cavities which are isolated through the piston(15) and not directly communicated with each other are formed in the shell, namely the upper cavity (51) and a lower cavity (52); the upper cavity (51) and the lower cavity (52) drive the piston(15) to act through pressure change in the cavities, and the valve assembly and the piston(15) make piston motion relative to the shell together. According to the LNG-form pneumatic liquid feeding gun, a liquid feeding opening is locked / released through the claw assembly, and the shell is a non-heat-conductive split type shell, so that the front end and the rear end of the LNG-form pneumatic liquid feeding gun do not conduct heat with each other, and the interior and the exterior of the LNG-form pneumatic liquid feeding gun do not conduct heat with each other.
Description
technical field [0001] The invention relates to a filling device for liquefied natural gas, in particular to an LNG program pneumatic liquid filling gun. Background technique [0002] In the prior art, the LNG filling gun is manually operated. When filling the LNG vehicle, the operator docks the filling gun with the gas filling port installed on the LNG vehicle, and then rotates the handle forward, that is, along the In the direction of the filling nozzle, lock the liquid filling gun tightly on the gas filling port. While this process is going on, the channel of the liquid filling gun is connected with the gas filling port, and the LNG liquid is started to be filled into the LNG vehicle through the channel of the liquid filling gun; after the filling is completed, The operator rotates the handle backward to the initial state, presses the handle backward, opens the jaws to release the gas filling port, pulls out the liquid filling gun, and separates the liquid filling gun fro...
