Description

A kind of logical sump turn-over stop valve
Technical field
The utility model relates to a kind of logical machine turn-over stop valve.
Background technique
Logical machine fuel evaporation gas is logical machine to one of pollution sources of atmosphere, there are in recent years many developed countries how it to be classified as the pressure standard, for example " Americanologist machine EPA phase III rules " and " the CARB rules " of the U.S., compulsory laws and regulations requirement has been made in discharging to the fuel evaporation pollutant of logical machine, if the made in China logical owner outlet U.S. and Europe, in order to satisfy corresponding Abgasgesetz, necessarily require exactly to install the fuel evaporation pollutant control gear additional at logical machine, one of indispensable parts of such device are exactly the fuel tank turn-over stop valve, its effect is that logical machine is when running into unexpected situation of overturning, prevent fuel oil by outside the fuel evaporation gas drawing-off mouth outflow machine, jeopardize logical machine and personal safety.
At present, all logical machine fuel evaporation pollutant control gear all are at existing fuel tank special-purpose fuel evaporation gas drawing-off mouth to be set, then install the system and devices such as turn-over stop valve additional, this method need to be transformed fuel tank, in fuel tank production, set up process, particularly when logical machine is installed control gear, because the reprocessing of the fuel tank after using welding is very dangerous, changes fuel tank for this reason and then can cause the too high and wasting of resources of expense.And set up the fuel evaporation gas drawing-off mouth and also increased corresponding fittings cost.
Summary of the invention
For above-mentioned technological deficiency, order of the present utility model just is to overcome the deficiency of above-mentioned prior art, provide a kind of simple in structure, easy for installation, the fuel box cover type turn-over stop valve of low cost of manufacture, reduce the manufacture cost of logical machine fuel evaporation pollutant control gear and having the mounting cost of using on the logical sump now, also saved the expense of fuel tank cap.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of logical sump turn-over stop valve, comprise a valve body, in valve body, consist of an active chamber, a spool is arranged in described active chamber, and described spool lower end is provided with spring, and the spring lower end is provided with valve seat, the valve body outside is provided with the installation gum cover, described installation gum cover is located between fuel tank and the described valve body, and described valve body and described valve seat are clamping matching, and the vent of described active chamber and the head of described spool are the pointed cone fitted seal.
Further, described spool is closed the fluid stopping performance by what spring cooperated control spool and active chamber.
Further, the material of described valve seat can be stainless steel, POM and plastics.
Further, the described interface of giving vent to anger adopts stepped design.
Further, described spool can be needle-valve or ball valve.
The beneficial effects of the utility model are: the utility model is integrated turn-over stop valve, fuel tank cap and fuel vapor drawing-off mouth, do not need the fuel vapor drawing-off mouth is set on fuel tank in addition specially, thereby can reduce the manufacturing expense of vehicle fuel oil evaporation pollutant control gear.And this turn-over stop valve or a fuel tank cap, direct forced installation, very convenient, saved the manufacturing expense of fuel tank cap.In addition, the application's fuel box cover type turn-over stop valve is simple in structure, low cost of manufacture, and can be installed in easily and have now on logical sump mouth, the fuel tank of different bores is installed, as long as change the installation gum cover of various outer diameter, just can satisfy installation requirements.And turn 90 degrees the gasoline outflow that can cut off in the fuel tank when turning over, and prevent from causing the fuel evaporation device to damage, and fuel oil leak and cause personnel's danger, realized the function of turn-over stop valve.The employing stepped design of air outlet can satisfy the sebific duct of multiple caliber the cost that this turn-over stop valve effectively reduces mounting cost and the fuel tank cap of fuel evaporation pollutant control gear is installed.And be easy for installation, and can work as fuel tank cap and use.Actual meaning is very great, is worthy to be popularized very much, and has good economic and social benefit.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Logical machine oil box lid type turn-over stop valve of the present utility model comprises a valve body, in valve body, consist of a valve active chamber, a spool is arranged in the valve active chamber, the centre of valve body has one gum cover is installed, and a control spring is placed in the spool lower end, is provided with a stainless steel base in the lower end of valve body, base is that seizing type is connected with valve body, have four to advance vent on valve body four limits, it is drive fit that the size of gum cover and the size of reservoir port are installed, and seals.Also be provided with the mounting spring location on the base, also be provided with air outlet hole, oil gas can be gone out by turn-over stop valve smoothly, the upper air outlet of valve body is exactly the fuel-steam fairlead.
Further, as shown in Figure 1, logical sump turn-over stop valve of the present utility model comprises a valve body 1, at valve active chamber 2 of valve body 1 interior formation, a spool 3 is arranged in valve active chamber 2, and there is spring 4 spool 3 lower ends, and there is valve seat 5 the spring lower end, the gum cover 6 of installation is arranged on the valve body, and valve body 1 is clamping matching with valve seat 5.It is characterized in that, are pointed cone fitted seal at the vent of the lower end of valve body 1 active chamber 2 and the head of spool 3.Under normal circumstances, turn-over stop valve is idle, and the gravity compressed spring 4 of spool 3 does not have the pointed cone of spool 3 and the vents seal of valve active chamber 2, and it is unimpeded keeping oil gas to go out.Only running into logical machine turns over and turn 90 degrees or more when wide-angle, such as Fig. 2, spool begins to start, under the control of spring 4, the head of spool 3 is that pointed cone contacts with the ventilating hole of valve active chamber 2, blocks vents seal, leak thereby realize cutting off fuel oil, prevent from damaging logical machine and jeopardize human-body safety.Realized the function of turn-over stop valve.Original fuel tank 8 will be installed the fuel evaporation device, and fuel tank does not have the fuel-steam drawing-off mouth, and the present as shown in Figure 1 position of reservoir port is the fuel tank cap position, need to open in other place a fuel-steam drawing-off mouth, and the Novel turning flow-stop valve has just been realized the effect of fuel-steam drawing-off mouth, and has made up the function of fuel tank cap.And the fuel tank that can satisfy different pore size by replacing two different installation gum covers as shown in Figure 3 and Figure 4 uses, and adopts forced installation, and is very convenient.As shown in Figure 5, described spool 3 can be needle-valve or ball valve 10, also can be the other forms of valve that meets the utility model design.
