Abstract
The invention provides a check valve for an oil filling gun. The check valve is built-in in the front end of an oil inlet pipe of the oil filling gun. The check valve comprises a rear gland, an O-shaped ring, a valve, a check valve body, a reset spring and a guide shaft, wherein the rear gland is connected with the check valve body through threads, and a connection position between the rear gland and the check valve body is sealed by an O-shaped ring; the check valve body and the guide shaft are integrally formed parts, and the guide shaft is located in the check valve body; the valve sleeves the outer part of the guide shaft, and the valve and the rear gland are subject to end face seal; the rear part of the valve is provided with a reset spring for supporting, and an oil inlet is formed in the rear gland. According to the check valve for the oil filling gun provided by the invention, the valve can be opened when the oil filling gun is used for oil filling, and the valve is closed when an oil way is cut off, therefore the valve control be flexibly controlled to be opened and closed; meanwhile, by adopting a line sealing structure, the sealing property is good, and the leakage cannot be caused.
Description
Technical field
The invention relates to a kind of equipment unit of gas station, especially about a kind of nozzle one-way valve.
Background technique
During 2008 Olympic Games, China Petrochemical Industry transforms Beijing gas station, improves service station environment, reduce gasoline volatilization, achieve good effect, obviously improve the air quality of periphery, in May, 2013, China Petrochemical Industry's bid carries out pipeline modification by for domestic all gas stations, and the volatilization gas of collection is processed again be converted to gasoline, by the end of the end of the year 2012, national gas station statistical magnitude will be 96313, the gasoline gas of annual volatilization has 2,000,000 tons, and economic loss reaches 15,000,000,000 yuan.
During gas station's pipeline modification, use nozzle generally to have oil dripping phenomenon after oiling, not only waste is caused to fuel oil, secondly also again can pollute the environment of gas station, although the amount that water clock occurs each is also few, be accumulated to certain hour, be also a very surprising quantity, the waste caused is also very serious.
As can be seen here, above-mentioned existing nozzle with in use in structure, obviously still has inconvenience and defect, and is urgently further improved.In order to solve above-mentioned Problems existing, relevant manufactures there's no one who doesn't or isn't seeks solution painstakingly, but have no applicable design for a long time to be completed by development, and common product does not have appropriate structure to solve the problem, this is obviously the anxious problem for solving of relevant dealer always.
Summary of the invention
The object of the present invention is to provide a kind of nozzle one-way valve, technical problem to be solved it is possible to open valve while oiling, throttle down while cutting off oil circuit, the folding of sensitive control valve, simultaneously, adopt linear sealing structure, favorable sealing property, can not leak.
The object of the invention is to realize by the following technical solutions.The invention provides a kind of nozzle one-way valve, be built in the front end of nozzle oil outlet tube, it comprises: rear pressing cover, O type circle, valve, check valve body, Returnning spring and the axis of guide, wherein, described rear pressing cover is connected with described check valve body by screw thread, and utilizes described O type circle to seal in joint; The part that described check valve body and the axis of guide are formed in one, and the axis of guide is positioned at check valve body inside; Valve sleeve is located at axis of guide outside, and carries out end face seal with rear pressing cover; The rear portion of valve is provided with Returnning spring and supports.
Object of the present invention also can be applied to the following technical measures to achieve further.
Preferably, aforesaid described nozzle one-way valve, wherein said rear pressing cover is provided with oil inlet hole.
By technique scheme, nozzle one-way valve of the present invention at least has following advantages and beneficial effect: nozzle one-way valve of the present invention can open valve while oiling, throttle down while cutting off oil circuit, the folding of sensitive control valve, simultaneously, adopt linear sealing structure, favorable sealing property, can not leak.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to technological means of the present invention can be better understood, and can be implemented according to the content of specification, and can become apparent to allow above and other object of the present invention, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
