Embodiment Construction

[0016] The following will be further described in conjunction with the accompanying drawings, not to limit the scope of the present invention.

[0017] see figure 1 As shown, the present invention comprises oil tank 1, oil outlet pipe 15, oil inlet pipe 9, manual reversing valve 6, oil suction oil filter 2, oil pump 3, jacking oil cylinder 11 and pressure gauge 6; The range of pressure gauge 6 is 0-40MPa , used to display the pressure of the oil circuit on site, it is controlled by a pressure gauge switch 5, press the pressure gauge switch 5 by hand, the pressure gauge 6 will display the current pressure; lift the slide valve on the pressure gauge switch 5 to cut off the high-pressure liquid oil circuit At the same time, the pressure medium in the oil pipe between the slide valve on the pressure gauge switch 5 and the pressure gauge can be relieved, and part of the oil can flow back to the oil tank 1. The manual reversing valve 8 is connected to the lock control valve plate 1...

Abstract

The invention relates to a jacking device of a trailer for a secondary natural gas fueling station. The jacking device comprises an oil tank, an oil outlet pipe, an oil inlet pipe, a hand-directional valve, an oil absorption filter, an oil pimp and a jacking cylinder. One end of the oil absorption filter is communicated with the oil tank through the oil outlet pipe, and the other end of the oil absorption filter is connected with the oil pump through the oil outlet pipe. The oil pump is connected with the hand-directional valve through a one-way valve arranged on the oil outlet pipe. Two fast-mounted oil pipes are connected to the hand-directional valve. The other end of each fast-mounted oil pipe is connected to a lock-control valve plate which is internally provided with a hydraulic control one-way valve. The jacking cylinder is connected with the fast-mounted oil pipes through the hydraulic control one-way valve. The jacking device is simple, efficient, practical, low in cost and convenient to use.

Description

technical field [0001] The invention relates to a natural gas filling device, in particular to a trailer jacking device for a natural gas filling substation. Background technique [0002] Natural gas is a high-quality and clean energy and one of the most ideal fuels for environmental protection. At present, the natural gas industry is in a stage of vigorous development, gradually becoming one of the world's preferred energy sources. [0003] The chemical properties of natural gas are relatively stable. Under normal conditions, it does not react with oxygen, nor does it react with concentrated acid, concentrated alkali solution, or oxidant. However, it can react with chlorine gas as long as it is exposed to sunlight or heated, and it can spontaneously ignite when mixed with hydrogen fluoride. , in order to meet the market demand, in the hydraulic refueling sub-station system, the emitted gas medium is toxic. During the lifting process of the trailer, the general contact of t...
