Abstract
Disclosed is an overloading limiter, and the utility model relates to an overloading limiter for a container, in particular to the technical field of an overloading limiter for the class of a liquefied petroleum gas cylinder. The overloading limiter is composed of a cylinder-shaped valve body with an inlet and an outlet, and the lower end of the valve body is provided with a hinged seat groove which is hinged with a float rod. The other end of the float rod is connected with a float, the inner chamber of the valve body is sheathed with a big valve, and the diameter of the upper end is less than the lower end. A through hole is arranged on the big valve, and a small valve is arranged below the big valve. One end on the float rod which is contacted with the small valve is in concave-convex shape, and the big valve is provided with a spring. The utility model has the advantages of compact structure, artful design, high reliability, low cost and good effect.
Description
Technical field
The utility model relates to the excessive overfill-limiting device of container, relates in particular to the excessive overfill-limiting device technical field of LP gas cylinder class.
Background technique
At present, the excessive overfill-limiting device of known cost container lower, that have certain reliability is made up of valve body, valve rod, float and float lever, when liquid level raises, float drives the float lever mobile valve rod throttle down that moves, thereby reach excessive limit and use usefulness as, but, make valve rod have enough making every effort to overcome to obey filling pressure and cut-off valve, it is enough big that the volume of float is wanted, could reliable limit fill, because the container finish that has is less, the big float of can not packing into, such limit is filled mode just certain degree of difficulty when using.
Technology contents
The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, and is applied widely, and limit is filled effective excessive overfill-limiting device.
The utility model includes the cylinder valve of inlet/outlet, the lower end of valve body offers the hinged seat groove, be hinged with float lever, the other end of float lever connects float, and body cavity is arranged with big valve, and big valve upper end diameter is less than lower end diameter, big valve is provided with through hole, big valve below is provided with little moveable door, is provided with concavo-convexly with the little moveable door contacting point on the float lever, and big valve is provided with spring.
The upper and lower end of said big valve is provided with seal ring.
Said little moveable door and valve body are hinged.
The utility model compact structure, exquisite composition, reliability height, with low cost effective.

Accompanying drawing 1 is the structural representation of the utility model opening state
1 is valve body, the 2nd among the figure, spring, the 3rd, big valve, the 4th, little moveable door, the 5th, float lever, the 6th, float.
Accompanying drawing 2 is structural representations of the utility model closed condition
Embodiment
As shown in the figure, the utility model includes the cylinder valve 1 of inlet/outlet, and the lower end of valve body 1 offers the hinged seat groove, is hinged with float lever 5, the other end of float lever 5 connects float 6, valve body 1 inner chamber is arranged with a big valve 3, and big valve 3 upper end diameter are less than lower end diameter, and big valve 3 is provided with through hole, little moveable door 4 is located at the bottom of valve body 1 inner chamber, and be positioned at big valve 3 belows, be provided with tongue and groove with little moveable door 4 touching positions on the float lever 5, spring 2 is set on the big valve 3.
The upper and lower end of said big valve 3 is equipped with seal ring.
Said little moveable door 4 is hinged with valve body 1.The upper end cylindrical of valve body 1 is provided with screw thread.
Principle of the present utility model is: as shown in Figure 1, entered by valve inlet when filling liquid, at this moment big valve 3 does not block the import of valve body under the effect of spring, and little moveable door is withstood at the protruding place of float lever, and liquid can free in and out.As shown in Figure 2, after liquid level reaches specified altitude, buoyancy of liquid drives float lever 5 and moves, and the little moveable door in the valve body falls into the recess of float lever, and the passage in the valve body is closed by little moveable door 4, and the liquid that fills also continues to enter in the valve body, because the upper and lower area of big valve in the valve body does not wait, the liquid that fills produces a hydraulic coupling that moves big valve in valve body, and filling pressure is bigger, the power of closing is bigger, and valve closing is more reliable.
Claims (3)
1, a kind of excessive limit flushing device, it includes the cylinder valve of inlet/outlet, and the lower end of valve body offers the hinged seat groove, is hinged with float lever, the other end of float lever connects float, it is characterized in that body cavity is arranged with a big valve, big valve upper end diameter is less than lower end diameter, big valve is provided with through hole, big valve below is provided with little moveable door, is provided with concavo-convexly with the little moveable door contacting point on the float lever, and big valve is provided with spring.
According to the said excessive limit flushing device of claim 1, it is characterized in that 2, the upper and lower end of big valve is provided with seal ring.
