As a kind of prioritization scheme, aforementioned controllers connect instrument by CAN bus.
As a kind of prioritization scheme, it is connected through a screw thread between aforementioned pressure sensor and intermediate gas cylinder.
As a kind of prioritization scheme, valve is additionally provided between aforementioned pressure sensor and intermediate gas cylinder.
As a kind of prioritization scheme, said valve is ball valve.
It uses and is threadedly coupled as a kind of prioritization scheme, between aforementioned pressure sensor and valve, valve and intermediate gas cylinder
Between also using be threadedly coupled.
As a kind of prioritization scheme, the connection screw thread between aforementioned pressure sensor and valve is pipe screw thread, and valve is in
Between connection screw thread between gas cylinder be also pipe screw thread.
A kind of loading machine, it is characterized in that：Using above-mentioned LNG loading machine delayed startup devices.
The advantageous effect that the present invention is reached：
1. the present invention detects the gas pressure of intermediate gas cylinder using pressure sensor, and the pressure of intermediate gas cylinder is real-time
Controller is transferred to, when controller detects that the pressure of intermediate gas cylinder reaches the requirement of engine start, just makes starting relay
Coil is powered, at this moment the contact closure of starting relay, and starter motor obtains electric, startup engine.The invention avoids existing skills
In art, key switch is opened, starts engine at once, is completely opened so that engine does not completely vaporize in natural gas
Dynamic the phenomenon that starting, extends the service life of engine.
2. valve is additionally provided between pressure sensor and intermediate gas cylinder, the preferable ball valve of the preferred leakproofness of valve, as far as possible
The phenomenon that reducing gas leakage using being threadedly coupled between valve and intermediate gas cylinder and pressure sensor, is conveniently replaceable pressure
Force snesor and valve, pipe screw thread further improve the leakproofness of junction.
3. controller connects instrument, instrument is equipped with indicator light, when the pressure of intermediate gas cylinder reaches opening for controller setting
During dynamic pressure, indicator light lights, convenient for gas cylinder among driver's real-time monitored pressure and whether reach startup requirement；The opposing party
The design of face, instrument and indicator light also allows for the detection and repair of service worker.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and be not intended to limit the protection scope of the present invention and limit the scope of the invention.
As shown in Figure 1：The invention discloses a kind of LNG loading machines delayed startup device, including switch 1, intermediate gas cylinder 2,
Controller 3, pressure sensor 4, starting relay 5, starter motor 7 and total gas cylinder 8, total gas cylinder 8 are connected by intermediate gas cylinder 2 and sent out
Motivation, intermediate 2 connecting valve 1 of gas cylinder, intermediate gas cylinder 2 are equipped with pressure sensor 4, and pressure sensor 4 connects controller 3, control
Device 3 is connected with the coil of switch 1, starting relay 5, and starter motor 7 connects power supply by starting relay 5.Total gas cylinder 8 is deposited
Liquified natural gas (LNG) is stored up, is equivalent to the mailbox of vehicle.
For the ease of gas cylinder 2 among driver's real-time monitored pressure and whether reach startup requirement, controller 3 is also connected with
Instrument 6, instrument 6 are additionally provided with indicator light 61.Specifically, controller 3 connects instrument 6 by CAN bus.
For the ease of the replacement of pressure sensor 4, preferably it is connected through a screw thread between pressure sensor 4 and intermediate gas cylinder 2.
When needing replacing pressure sensor 4, to prevent intermediate gas cylinder 2 from leakage occurs, it is necessary to cut off intermediate gas cylinder 2 and pressure sensor
