Embodiment 1

[0026] Embodiment 1: A gas cylinder inflation control device, which includes a gas tank 1 (compressed gas inflation equipment) and a gas cylinder 2 as a gas source for gas supply, and the device is suitable for various applications of compressed liquefied gas inflation control, Such as compressed air, oxygen, liquefied petroleum gas, natural gas, inert gas or corrosive gas, etc., wherein, the output end of the gas tank 1 is pressurized by the gas pump (or compressor), and then connected to the gas through the gas connector 10. bottle 2. It also includes a cooling mechanism. The pressure supply main pipe 12 is drawn from the inflation pipe 11 to work on the cooling mechanism. The evaporator 7 at the output end of the cooling mechanism is connected to the gas cylinder through a heat-conducting component, and is controlled by the controller according to the inflation progress in the gas cylinder 2. The power of the air pump increases until the cylinder is full and stops.

Embodiment 2

[0037] Embodiment 2: as Figure 5 As shown, on the basis of the improvement of the condenser in Embodiment 1, in this embodiment, a shaft tube 33 is connected to the rear side of the sealing box 30 through a fixing seat 32, and one end of the handle 34 is set on the shaft through a shaft sleeve 35. On the outside of the tube 33, a connector 36 is arranged at the end of the shaft tube, and a guide rod 39 is set on the other end of the handle through the sleeve 2 37. The front end of the guide rod is designed as an arc-shaped hook body 38 for clamping the gas cylinder. A rear seat and a handle 40 are arranged at the rear end of the guide rod, and a thrust spring is connected between the second axle sleeve and the rear seat.

Embodiment 3

[0038] Embodiment 3: A kind of gas tank inflation control device, such as Figure 6 As shown, the compressed gas from the compressed gas pipeline or the total storage tank 42 is introduced into the compressed gas transport vehicle-mounted gas tank through the inflation pipe, the air pump and the inflation joint 10, and the gas tank as described in Embodiment 1 is arranged near the vehicle-mounted gas tank. Cool down the power system. like Figure 6 As shown in , the dotted line part is the system arranged on the compressed gas transport vehicle. The detailed structure of the system is described in Implementation 1, and will not be described in detail. The system has three external joints: the inflation joint 10 and the pressurization joint 43 And return air joint 44. The inflation joint 10 is connected with the inflation pipe 11 , the booster joint 43 is connected with the booster main pipe 12 , and the air return joint 44 is connected with the return main pipe 13 .

Abstract

The invention discloses a gas cylinder inflation control device. The gas cylinder inflation control device comprises a gas tank serving as a gas source and used for supplying gas and a gas cylinder, wherein an inflation pipe at the output end of the gas tank is connected with the gas cylinder through an inflation connector after being pressurized by a gas pump; the gas cylinder inflation control device further comprises a cooling mechanism, and a pressure supply header pipe is led out of the inflation pipe and used for acting on the cooling mechanism; and an evaporator at the output end of the cooling mechanism is connected with the gas cylinder through a heat conduction component, and a controller controls the power of the gas pump to be increased according to the inflation progress in the gas cylinder till the gas cylinder is filled. According to the gas cylinder inflation control device, refrigeration power can be automatically increased along with temperature rise of the gas cylinder due to increase of inflation pressure, a refrigeration system hardly participates in refrigeration work in the early stage of inflation, refrigeration cooling can be automatically carried out due to temperature rise in the gas cylinder in the later stage of inflation, and the refrigeration degree can be automatically changed along with temperature change of the gas cylinder.

Description

technical field [0001] The invention belongs to the technical field of gas cylinder inflation control equipment, and in particular relates to a control technology applied to compressed gas inflation equipment for gas cylinder inflation. Background technique [0002] Gas cylinders refer to refillable gas under normal ambient temperature (-40-60°C), with a nominal working pressure of 1.0-30 MPa (gauge pressure), and a product of pressure and volume greater than or equal to 1.0 MPa·L. , mobile pressure vessels for liquefied gases and liquids with a standard boiling point equal to or lower than 60°C. Gas cylinders are widely used, whether in the field of production or in the field of life, gas cylinders are almost inseparable. As pressure equipment, its bearing medium is generally flammable, explosive, toxic, and highly corrosive. The use environment is more difficult than other pressure vessels due to its characteristics of movement, repeated filling, unfixed operators and cha...
