Abstract
The utility model relates to an automatic cut-off communicating pipe, which comprises a communicating pipe (1), a pipe seat (2), a valve seat (3), a valve core (4), a valve rod (5), an open valve spring (6), a mounting rack (7), a steel ball spring clinch (8) and an inhaul cable (9). The utility model has the advantages that the automatic cut-off communicating pipe is capable of being used to supply air for an aerostat separation type empennage, can beneficially protect floating gas in a gas bag from leaking when the communicating pipe is damaged or broken caused by the external environment after a balloon empennage and a main bag body are connected through the pipe seats which are arranged on the two ends of the communicating pipe, thereby guaranteeing the rigidity and the shape of an aerostat, and protecting other parts of a system from being damaged.
Description
Technical field
The utility model relates to the pipeline field, relates to the connecting tube of playing interconnect function between two containers of gas or fluid being equipped with particularly.
Background technique
Be used for two connections that the container tax-included price matter of gas or fluid is housed connecting tube.When the balloon empennage of aerostatics balloon and main bag body by this connecting tube two ends base be connected after, when rupturing under the effect of connecting tube in external tensile force, if closing containers and the interface of connecting tube automatically, the flowing medium in the container can leak from jointing.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned deficiency of existing connecting tube, and a kind of automatic cut-off formula connecting tube is provided.
The utility model by connecting tube, base, valve seat, spool, valve rod, open valve spring, scaffold, steel ball spring card, drag-line and form; A pair of base is installed in the connecting tube two ends respectively, valve seat is installed on the base, scaffold is fixed on the valve seat, the cross bar of scaffold is provided with pilot hole, valve rod is installed in the pilot hole of scaffold, one end of valve rod links to each other with spool, spool is positioned at valve seat, valve-closing spring is enclosed within on the valve rod, one end is against on the spool, and the other end is against on the cross bar of scaffold, has locking aperture on valve rod, have the steel ball spring mounting hole in the pilot hole on the scaffold cross bar, the steel ball spring card is installed in the steel ball spring mounting hole; Drag-line one end links to each other with valve rod, and the base that the other end is relative with valve seat links to each other.
The utility model has the advantages that: it can be used for aerostatics separated type empennage air feed aspect; when balloon empennage and main bag body by this connecting tube two ends base be connected after; because when external environment causes connecting tube damage or fracture; buoyancy gas leak in the protection air bag that can be favourable, impaired with the rigidity and the profile protective system miscellaneous part that guarantee aerostatics.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a pair of base 2 is installed in connecting tube 1 two ends respectively, valve seat 3 is installed on the base 2, scaffold 7 is fixed on the valve seat 3, the cross bar of scaffold 7 is provided with pilot hole, valve rod 5 is installed in the pilot hole of scaffold 7, one end of valve rod 5 links to each other with spool 4, spool 4 is positioned at valve seat 3, and valve-closing spring cover 6 is on valve rod 5, and an end is against on the spool 4, the other end is against on the cross bar of scaffold 7, have locking aperture on valve rod 5, have the steel ball spring mounting hole in the pilot hole on the scaffold cross bar, steel ball spring card 8 (being made of steel ball and spring) is installed in the steel ball spring mounting hole; Drag-line 9 one ends link to each other with valve rod 5 by the monaural bolt, and the base 2 that the other end is relative with valve seat links to each other.
Using method and working principle: with aerostatics (balloon) that gas is housed is example, when balloon empennage and main bag body by this connecting tube two ends base be connected after, the spool of connecting tube is by opening valve spring with valve open, and the steel ball by the steel ball spring card sticks into the locking aperture on the valve rod, make the guide rod locking, valve is in open mode, and empennage and main bag body gas communicate.Awing, when external environment cause empennage come off cause connecting tube fracture after, connecting tube base after coming off spurs valve rod (also can directly use the electromagnetism Push-and-pull valve to pass through control electromagnetism Push-and-pull valve throttle down automatically after the connecting tube fracture is judged by system) by drag-line, makes spool with valve closing.Gas in the main bag body is not revealed,,, avoided system equipment impaired, win the repairing time to guarantee the rigidity and the profile of balloon to keep aerial balloon work.Also can directly use the electromagnetism Push-and-pull valve after the connecting tube fracture is judged by system, to pass through control electromagnetism Push-and-pull valve throttle down automatically, realize ending certainly function.Electromagnet is connected power supply when driving valve, and the pulling force of making progress for the monaural bolt makes valve open.
