Abstract

The utility model discloses a throttle pipe sleeve and a refueling pipeline with the throttle pipe sleeve. The throttle pipe sleeve comprises an annular throttle plate with throttle holes, wherein the edge of the outer circle of the annular throttle plate transversely extends out towards two sides of the annular throttle plate so as to form an auxiliary end portion. According to the throttle pipe sleeve and the refueling pipeline with the throttle pipe sleeve, due to the fact that the throttle holes are integrated onto a pipe sleeve of a flexible joint of a fuel oil pipeline, connection tightness of the pipeline can be guaranteed only through one part, and furthermore the throttle pipe sleeve and the refueling pipeline with the throttle pipe sleeve have a throttling function. When the throttle pipe sleeve and the refueling pipeline with the throttle pipe sleeve are used, a user only needs to simply replace the pipe sleeve, no complicated installation step is needed, experimental time is reduced, and convenience is improved.

Description

A kind of throttling pipe box and the filling conduit that contains this throttling pipe box

Technical field

The filling conduit that the utility model relates to a kind of throttling pipe box and contains this throttling pipe box.

Background technique

Fuel loading system needs throttle orifice to control flow and calculates refueling time.In the middle of actual experiment, need to be by the replacement of a series of different size inner diameter hole, test repeatedly, statistics could finally obtain the size of best throttle orifice.And the existing device with throttle orifice, extra being fit in fuel loading system conventionally, need to expend more manpower and time, can not reach easy effect.

Model utility content

Because prior art exists above-mentioned problem, the utility model proposes a kind of throttling pipe box, it can address the above problem effectively.

The utility model addresses the above problem by the following technical programs:

A throttling pipe box, comprises that one is provided with the ring Rectifier plate of throttle orifice, by the edge of the cylindrical of this ring Rectifier plate, to both sides horizontal extension, forms auxiliary end.

Throttling pipe box is added and is made by metal material machine.

The utility model also proposes a kind of filling conduit that contains throttling pipe box, it also comprises pipeline, the flange that is fixed on described pipeline one end that two needs connect, is arranged in the seal ring between described flange and described throttling pipe box and is fixed on the joiner joint that described throttle pipe puts, and one end of described flange is sheathed in the auxiliary end of described throttling pipe box.

Because the utility model is integrated into throttle orifice in the pipe box of flexible joint, only need component to guarantee the sealing that pipeline connects, possessed again the requirement of throttling; In use, as long as simple, replace pipe box, do not need complicated installation steps, can shorten experimental period, improve convenience.

Accompanying drawing explanation

Fig. 2 is the utility model embodiment's use view;

Fig. 3 is the sectional view of the utility model embodiment's use state.

Embodiment:

Below in conjunction with embodiment, describe the utility model in detail.

Shown in Figure 1, be the utility model embodiment's throttling pipe box, comprise that one is provided with the ring Rectifier plate 1 of throttle orifice 11, by the edge of the cylindrical of this ring Rectifier plate 1, to both sides horizontal extension, form

auxiliary end

12 and 13.

Described throttling pipe box is added and is made by metal material machine.

Shown in Fig. 2 and Fig. 3, use the filling conduit of throttling pipe

box connecting pipeline

2 and 3, also comprise

pipeline

2 and 3, the flange 4 that is individually fixed in described

pipeline

2 and 3 one end that two needs connect, be arranged in the seal ring 5 between described flange 4 and described throttling pipe box and be fixed on the joiner joint 6 that described throttle pipe puts, one end of described flange is sheathed in the

auxiliary end

12 and 13 of described throttling pipe box.

During use, first at two, need the pipeline 2 of connection and 3 the upper flange 4 of terminal part difference spinning (or welding); Then in the end recesses of flange 4, card is established a seal ring 5, coordinates with throttling pipe box the effect of playing sealing; Then the auxiliary end of throttling pipe box is filled in respectively in the one end that the flange on two pipelines is provided with to seal ring, finally fixing by coupling piece joint 6.Two pipelines are fixed on two auxiliary end of throttling pipe box by flange seal, when refueling, oil passes through from throttle orifice, realizes current limliting object, and there will not be the problem of leakage.

Convenience of the present utility model is to manufacture the throttling pipe box of a series of different internal orifice dimensions, conveniently in test, obtains the test data of desirable flow control, thereby determines the required pipe box size of system.

Throttling pipe box of the present utility model is integrated into throttle orifice among the pipe box of flexible joint, and the sealing that only needs simple component can complete pipeline is communicated with, and can play again the characteristic requirements of throttling.

Should be understood that these mode of executions are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
