Description
Technical Field
The invention relates to the technical field of a snap valve, in particular to a snap valve for an oiling machine.
Background
The gasoline station oil gas recovery means that in the process of loading and unloading gasoline and refueling vehicles, volatile gasoline oil gas is collected, and the purpose of recycling is achieved by one or two methods of absorption, adsorption or condensation and the like, or the pollution of the oil gas is reduced, or the oil gas is changed into liquid from gas state and then changed into gasoline again. The secondary oil gas recovery of a gas station is a ring of oil gas recovery, which prevents the environment from being polluted by the overflow of oil gas in the process of transferring gasoline, and the secondary oil gas recovery is popularized. In the process of automobile refueling, the snapping valve is a safety protection device which is arranged for preventing the oil gun from being removed in time after the oil gun is completely added, and the automobile is directly driven away, so that the automobile, the refueling machine and other related equipment are damaged, and potential safety hazards are caused. The abruption valve is generally arranged between the oiling machine and the oil pipe, and when the conditions occur, the abruption valve can cut off the connection between the oiling machine and the oil pipe, so that safety accidents are prevented.
At present, the existing breaking valves on the market are mostly disposable products, and can cut off an oil way but not cut off an oil gas recovery gas way. When breaking the valve fracture, tanker aircraft and vapor recovery vacuum pump do not have stop work, and the oil circuit has cut off, but the gas circuit still is drawing the air, and a large amount of air gets into underground oil storage tank, because it is not sending out oil outward, and the volume exchange can't be accomplished to lead to a jar internal pressure to increase, for the internal pressure of balanced jar, the vacuum pressure cap of filling station underground oil storage pipe breather pipe upper end is opened, in discharging the atmosphere to oil gas, can lead to the polluted environment. Moreover, when a snap-off accident occurs, the gasoline station cannot be immediately restored because it takes time to replace a new snap-off valve.
Moreover, in the secondary oil gas recovery process, in order to realize 1: 1 volume exchange, and a gas-liquid ratio regulating valve is arranged in a gas recovery link and is generally arranged between an oil pipe and an oil gun. Specifically, in order to arrange a breaking valve and a gas-liquid ratio regulating valve on an oil pipe of an oiling machine, two methods are generally adopted, wherein the first method is to add a short oil pipe, install the breaking valve between the short oil pipe and a long oil pipe, the short oil pipe is connected with the oiling machine, and the gas-liquid ratio regulating valve is installed at an oil inlet position of an oil gun and is connected with the long oil pipe; in another mode, a gas-liquid ratio regulating valve and a breaking valve are directly and serially installed at the tail end of the oil filling gun; the first method wastes a short oil pipe and the second method results in an inflexible and heavy fuel gun.
In addition, current abruption valve directly carries out fixed connection with oil pipe usually, and the both ends of oil pipe are generally the fixed head, and is unable rotatory, and it is not good to place when the oil gun, can produce the distortion on the oil pipe, in order to arrange oil pipe and oil gun in order, needs the waste time.
Therefore, how to solve the technical problems that the prior art is mostly a disposable product, which can cut off an oil path, but does not cut off an oil gas recovery gas path and cannot be recovered immediately after being cut off is an important technical problem to be solved by the personnel in the field.
