Abstract
The utility model provides a cipher anti-theft valve, which is composed of a valve body, an inner valve rod, an outer valve rod, a seal ring and compression nuts, wherein, the inner valve rod is fixed in the outer valve rod which is fixed in the valve body by a compression bolt; the seal ring is arranged between the outer valve rod and the valve body. The cipher anti-theft valve has the advantages of reasonable design, simple structure, easy manufacturing, small size, convenient operation, etc. The utility model can be used for the fuel tank of a vehicle and other special pipelines.
Description
The utility model relates to a kind of valve, specifically a kind of cipher anti theft valve with cipher lock.
On the pipeline of carrying liquid, gas, all want the quantity delivered of mounted valve in order to controlling liquid gas, at present, the various valves that are used for control gaseous, liquid conveying are a lot, have electronic, pneumatic, still manual or the like, but also do not have the valve for guarding against theft of band cipher lock on relevant document, to publish or product public use aborning arranged.With regard to by employed fuel tap in the vehicle oil way, the oil stealer is easy to steal fuel oil in the fuel tank by the fuel tap on the fuel tank, if can use a kind of valve for guarding against theft with cipher lock just can prevent effectively that other people from stealing oil plant by fuel tap.
The purpose of this utility model provides a kind of cipher anti theft valve that is used to prevent other people unauthorised opening use with cipher lock, is mainly used in the safe antitheft of fuel tank.
The purpose of this utility model realizes in the following manner, in valve body, will be compounded in the duct chamber in the lower end fixed valve body of inside and outside valve rod of one by gland nut, be arranged on the inside and outside valve rod of duct chamber and have oil-through hole, when the central lines of duct chamber in oil-through hole on the inside and outside valve rod and the valve body, pipeline is open-minded, oil plant could pass through, otherwise pipeline keeps closing.The upper surface of gland nut and be installed on the dial of inside and outside valve stem tip and be carved with number, dial is controlled the angle of swing of inside and outside valve rod, have only when the number on the gland nut upper surface and when being installed in the number of being carved on the inside and outside valve stem tip dial and rearranging fixing six figure places, on the inside and outside valve rod center line of oil-through hole could with the central lines of duct chamber in the valve body, pipeline could be opened.Equally, when the number on the gland nut upper surface with when being installed in the number of being carved on the inside and outside valve stem tip dial and can not rearranging fixing six figure places, on the inside and outside valve rod center line of oil-through hole can not with the central lines of duct chamber in the valve body, duct chamber is ended by inside and outside valve rod, and duct chamber is obstructed.Each cipher anti theft valve six figure place has nothing in common with each other, and has only user oneself to know, thereby has played antitheft effect.For vehicle, oil circuit is obstructed, can not only prevent stolen, and can prevent to steal car, and oil circuit is obstructed, and vehicle then can't start.
Accompanying drawing 1 is the cross section structure schematic representation of cipher anti theft valve;
Accompanying drawing 2 is the plan structure schematic representation of cipher anti theft valve.
Explain below with reference to Figure of description cipher anti-theft valve of the present utility model being done.
Cipher anti-theft valve of the present utility model, its structure are by valve body 2, inner valve stem 8, outer valve rod 7, sealing ring 5 and clamp nut 6 consist of, and inner valve stem 8 is fixed among the outer valve rod 7, outer valve Bar 7 is fixed on by clamp nut 6 among the valve body 2, and sealing ring 5 is located at outer valve rod 7 and valve body 2 Between.
The bottom of valve body 2 is a duct chamber 1, the lower end of inner valve stem 8, outer valve rod 7 is positioned in the middle of the duct chamber 1, divide on the two side, lower end of inner valve stem 8 and outer valve rod 7 and have the oil-through hole 4,3 that communicates with duct chamber 1 up and down, the center line of the oil-through hole 4,3 of inner valve stem 8, outer valve rod 7 both sides and the center line of duct chamber 1 coincide, and the vertical projection on the cylindrical of the oil-through hole 4,3 of inner valve stem 8, outer valve rod 7 both sides and the center line of inner valve stem 8 does not coincide.
The upper end of inner valve stem 8, outer valve rod 7 is provided with dial 9,10, is carved with digital 11 on the upper surface of dial 9,10 and gland nut 2.
Embodiment:
Its processing and fabricating of cipher anti theft valve of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.But valve body, inside and outside valve rod, gland nut nylon, engineering plastics or metallic material machining are routinely made.Use also very simple and convenient, as make fuel tap on the oil tank of vehicle, just an end of cipher anti theft valve and fuel tank the are fixed together the other end and oil line pipe is connected together and gets final product, the driver wants to open oil circuit, just six figure place sign indicating numbers with dial and on above the gland nut are arranged on six figure places of regulation, are in anti-theft state as making valve closing, just number are dialled unrest, other people are owing to the 6 figure place sign indicating numbers of not knowing to stipulate, so be difficult to valve open.This cipher anti theft valve can prevent that not only fuel oil is stolen, and oil circuit is obstructed can to prevent directly that also vehicle is stolen.
Cipher anti-theft valve of the present utility model is compared with existing technology, have reasonable in design, structure is simple Single, be easy to the characteristics such as processing, volume is little, easy to use, not only can be used on the fuel tank of vehicle, Also can be used on other pipe specials. Thereby, have good value for applications.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
