Authentication is through the back, and check valve open in usual is by the solenoid valve locking, and later inflation equipment begins to aerify to liquefied gas cylinder, during not through the authentication, the solenoid valve is out of work, and check valve open in usual is closed under the effect of pressure differential, and the purpose is aerifyd in the restriction of getting up, and simple structure is reliable, and is with low costs.
Description
Technical field
This utility model relates to the valve technology field of cylinder for liquefied gas, is especially for cylinder for liquefied gas intelligent valve control field.
Background technology
Existing liquefied gas cylinder valve includes tradition common valve and intelligent valve；Existing liquefied gas cylinder valve exists following not enough:
Common valve, do not possess Intelligent Recognition and control function, owing to steel cylinder must be examined by force for 4 years, within 15 years, renew, and a piece of information label indicates the information such as the date of production with tradition common valve simple in construction and only steel cylinder, actually user usually selects simple and crude informal gas station nearby because of price or distance reason, and potential safety hazard is huge, and tradition common valve structure cannot effectively prevent the generation of this potential safety hazard.
Intelligent valve, although above-mentioned technical problem can be solved, but owing to existing intelligent valve structure is complicated, cost is high；And, intelligent valve is between main valve mechanism and steel cylinder, adds gas leakage point, there is leakage possible after closing valve switch, poor stability, and available additional solenoid is controlled and does not has restriction control action.
Summary of the invention
In sum, the purpose of this utility model is to solve the intelligent valve poor stability of existing cylinder for liquefied gas, and reliability is not enough, and proposes a kind of valve mechanism being applicable to cylinder for liquefied gas Based Intelligent Control.
By solving the technical problem that this utility model is proposed, the technical scheme used is: a kind of valve mechanism being applicable to cylinder for liquefied gas Based Intelligent Control, include valve body, be provided with in valve body into outlet passageway, valve body is provided with the main valve mechanism controlling to be turned on and off into outlet passageway；It is characterized in that: described entering is additionally provided with the check valve open in usual for stoping illegal inflation in outlet passageway, be additionally provided with the electromagnetic valve stoping check valve action open in usual when legal inflation on valve body, and electromagnetic valve is electrically connected with control module.
Described electromagnetic valve includes and is in, for the piston limiting check valve open in usual, the latch that opening remains stationary as, and drives the latch back-moving spring that latch resets and the electric magnet driving latch to move axially.
Described entering outlet passageway and include and be vertically connected with vertical passageway and interconnection, described check valve open in usual is located in interconnection.
Described check valve open in usual includes piston, drives piston to be in the piston reset spring of opening position, and the fixed cover for piston limit；The sidewall of described piston is provided with the draw-in groove coordinating clamping with electromagnetic valve；Described fixed cover is connected with interconnection inner wall tightening.
Described valve body is provided with the valve pocket loaded for electromagnetic valve, and the accent of valve pocket is provided with fit sealing part.
The beneficial effects of the utility model are: be connected with setting up communication between charger in control module of the present utility model, and after authentication is passed through, solenoid valves, check valve open in usual is by electromagnetic valve locking, and charger starts to inflate to cylinder for liquefied gas afterwards；Between control module and charger not authenticated time, electromagnetic valve does not works, owing to the air pressure in the air filling gun of charger is more than the air pressure of cylinder for liquefied gas, under the effect of pressure differential, check valve open in usual is closed, get up restricted charging purpose, simple and reliable for structure, low cost；It addition, after main valve mechanism closes, the combustion gas in cylinder for liquefied gas cannot be introduced in check valve open in usual, there is not extra gas leakage hidden danger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the preferred specific embodiment of accompanying drawing and this utility model, structure of the present utility model is further described.
With reference to shown in Fig. 1, this utility model has included valve body 1, is provided with into outlet passageway 2, is provided with the main valve mechanism 3 controlling to be turned on and off into outlet passageway 2 on valve body 1 in valve body 1；Described enters the check valve open in usual 4 being additionally provided with in outlet passageway 2 for stoping illegal inflation, is additionally provided with the electromagnetic valve 5 stoping check valve 4 open in usual action when legal inflation on valve body 1, and electromagnetic valve 5 is electrically connected with control module.
At present the outlet passageway 2 that enters in valve body 1 has generally comprised and has been vertically connected with vertical passageway 21 and interconnection 22, vertical passageway 21 is fastened and connected with steel cylinder, interconnection 22 connects for the balanced valve connecting gas-fired equipment, or docks with the charge gun of charger；Main valve mechanism 3 is located in vertical passageway 21, and interconnection 22 is located at by check valve open in usual 4 of the present utility model, stops using at gas-fired equipment, in the case of main valve mechanism 3 closes, can thoroughly prevent check valve 4 open in usual from leaking gas.
Described electromagnetic valve 5 includes and is in, for the piston limiting check valve open in usual, the latch 51 that opening remains stationary as, and drives the latch back-moving spring that latch resets and the electric magnet 52 driving latch to move axially；Moving axially downwards under after electric magnet 52 is energized, latch 51 is by magneticaction, latch 51 bottom is inserted in check valve 4 open in usual, thus interferes check valve 4 open in usual action, locking check valve open in usual 4.
Described check valve open in usual 4 is in opening under normal conditions, combustion gas freely can be flowed through interconnection 22 by steel cylinder to gas-fired equipment direction, after the charge gun connecting charger, if in the case of not interfered by electromagnetic valve 5, when the air pressure of charge gun end is more than air pressure in steel cylinder, check valve 4 open in usual is automatically switched off by gaseous-pressure.
Check valve 4 open in usual includes piston 41, drives piston 41 to be in the piston reset spring 42 of opening position, and the fixed cover 43 for piston limit；The sidewall of described piston 41 is provided with the latch 51 with electromagnetic valve 5 and coordinates the draw-in groove 411 of clamping；Described fixed cover 43 is connected with interconnection 22 inner wall tightening.Namely time not authenticated between control module and charger, control module is considered illegally to inflate, it is not powered on due to electromagnetic valve 5 during illegal inflation, the locked piston of latch 51 41 can not be driven, piston 41 is owing to closing air inlet after the gas momentum that discharged by charger charge gun after moving right compression piston back-moving spring 42, gas cannot pass through check valve 4 open in usual, the most just cannot be inflated steel cylinder；After illegal charge operation releases, making piston 41 reply normal position under piston reset spring 42 acts on, check valve 4 open in usual recovers opening automatically.
Described valve body 1 is provided with the valve pocket loaded for electromagnetic valve, and the accent of valve pocket is provided with fit sealing part.
