Description
Technical field
The utility model is related to a kind of gas station's operation and damages control system of overflowing, and fuel-economizing improvement is mainly carried out on nozzle.
Background technology
The mode refueled in gas station has two kinds, and one kind is that staff holds nozzle and refueled to in-car, another
It is that driver oneself holds nozzle to in-car oiling.Both oiling modes all have the problem of easy oil spilling is lost, and this is asked
Topic be primarily present in nozzle draw close and separate with automobile during, nozzle is in the process drawn close and separated with oiling center
In., may be when nozzle gun barrel have in place also when holding nozzle, the switch of nozzle is encountered in just error, so as to go out
The situation of existing oil leak.The first oiling mode, due to the skilled operation of staff, only may can overflow a small amount of oil.Second
Oiling mode is planted, because driver's refueling operation is more not familiar, it is thus possible to more oil can be overflowed.
Utility model content
The purpose of this utility model is that a kind of gas station's operation is provided to solve the above problems damages control system of overflowing
System.
The utility model is achieved through the following technical solutions above-mentioned purpose：
Control system of overflowing, including nozzle are damaged in a kind of gas station's operation, and the gun barrel of the nozzle is connect by sealed pipe
Head is connected with flowline, the flowline and is provided with one-way safety valve mechanism, the one-way safety valve mechanism it is fuel-displaced
Direction is consistent with the fuel-displaced direction of the gun barrel of the nozzle.
A kind of technical scheme selected as the utility model, the one-way safety valve mechanism include being fixed on it is described go out
Guide cylinder at oil pipe axis, it is enclosed in the guide cylinder and slidable guide rod and the sealing that is connected with the guide rod
Horn mouth is provided with plug, the flowline, the sealing-plug is the truncated cone-shaped structure matched with the bell-mouth structure of air, institute
The bigger diameter end for stating sealing-plug is connected and miner diameter end is towards the bell-mouthed inner side with the guide rod, is cased with the guide rod
The sealing-plug is pressed in the compression spring at the horn mouth.
A kind of technical scheme selected as the utility model, the guide cylinder is arranged on the flowline by fixed mount
Interior, one end of the compression spring is pressed on the fixed mount and the other end is pressed in the bigger diameter end of the sealing-plug.
A kind of technical scheme selected as the utility model, the sealing-plug is by hard round platform and is enclosed on the hard circle
Rubber sleeve composition on platform extrados, the bigger diameter end of the hard round platform is fixedly connected with the guide rod.
The beneficial effects of the utility model are：
The utility model is connected to the flowline with one-way safety valve mechanism at the gun barrel of nozzle so that work as oiling
The switch of rifle is depressed into can just open and be refueled to a certain degree, if being generally that nozzle switch is encountered in error,
It is not in then the situation of oil spilling.
Brief description of the drawings
Fig. 1 is partial cross structural representation of the present utility model；
Fig. 2 is the cross section structure diagram of sealing-plug described in the utility model；
In figure：1- nozzles, the sealed pipe joints of 2-, 3- flowlines, 4- sealing-plugs, 5- horn mouths, 6- compression springs, 7-
Guide cylinder, 8- fixed mounts, 9- guide rods, 41- hard round platforms, 42- rubber sleeves.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, the utility model includes nozzle 1, and the gun barrel of nozzle 1 is connected by sealed pipe joint 2
It is connected in flowline 3, flowline 3 and is provided with one-way safety valve mechanism, the fuel-displaced direction of one-way safety valve mechanism is with refueling
The fuel-displaced direction of gun barrel of rifle 1 is consistent.
When refueling, the switch of nozzle 1 is opened, the oil of nozzle 1 enters in flowline 3.If the switch of nozzle 1
Pressure is not in place, then the pressure suffered by one-way safety valve mechanism is smaller, then it is remained turned-off, and is not in the situation of oil spilling；
If the switch pressure of nozzle 1 is full, the pressure suffered by one-way safety valve mechanism is sufficiently large and opens it, so as to just may be used
Refuel.Flowline 3 and nozzle 1 are the Demountables being connected by sealed pipe joint 2, therefore are easy to safeguard and more
Change.
A kind of technical scheme selected as the utility model, one-way safety valve mechanism includes being fixed in flowline 3
Guide cylinder 7 at axis, it is enclosed in guide cylinder 7 and slidable guide rod 9 and the sealing-plug 4 that is connected with guide rod 9, flowline
Horn mouth 5 is provided with 3, sealing-plug 4 is the truncated cone-shaped structure matched with the structure of horn mouth 5, and the bigger diameter end of sealing-plug 4 is with leading
Connected to bar 9 and miner diameter end is towards the inner side of horn mouth 5, be cased with being pressed in sealing-plug 4 into the compression at horn mouth 5 on guide rod 9
Spring 6.Nozzle 1 is when fuel-displaced, and oil is main to be needed to overcome the pressure of compression spring 6, promotes left end of the sealing-plug 4 into figure to push away
It is dynamic so as to occur oily gap between the horn mouth 5 of sealing-plug 4 and flowline 3, so as to be refueled.If nozzle 1 is switched
Pressure is not in place, then oil pressure not enough, can not push sealing-plug 4 open.
A kind of technical scheme selected as the utility model, guide cylinder 7 is arranged in flowline 3 by fixed mount 8, pressure
One end of contracting spring 6 is pressed on fixed mount 8 and the other end is pressed in the bigger diameter end of sealing-plug 4.
A kind of technical scheme selected as the utility model, sealing-plug 4 is by hard round platform 41 and is enclosed on hard round platform 41
Rubber sleeve 42 on extrados is constituted, and the bigger diameter end of hard round platform 41 is fixedly connected with guide rod 9.The sealing-plug that rubber sleeve 42 is
4 when being crushed at horn mouth 5, can good seal, be not in the situation of oil spilling.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
Any modifications, equivalent substitutions and improvements made within new spirit and principle etc., should be included in guarantor of the present utility model
In the range of shield.
