It states fore-stock and after-poppet to correspond and hinged, is connected with the rubber bag tank between adjacent fore-stock and adjacent after-poppet
Wall；
The through-hole of the utricule head end is hinged with the valve body 3 of taper, and the head end of the valve body is opening-like, the opening of the valve body
Place is equipped with adjusting nut 31, and the inside of the valve body is equipped with for closing the ringent regulating mechanism, the regulating mechanism packet
Containing the valve inner is arranged in and is hollow loop bar 32, it is equipped with valve rod 33 in the loop bar, the head end of the valve rod is set
There is the spool 34 for blocking the adjusting nut, spring 35 is arranged on the loop bar, the top of the spring is arranged in institute
The bottom of spool is stated, and in its natural state, the spool resists the adjusting nut under the action of the spring and realizes sealing, is pressing
Under power effect, the spool and valve rod can be moved into loop bar.The bottom end of the valve body and the head end of the utricule are hinged, and institute
The tail end for stating valve body is equipped with front support rod 4, and the tail end of the front support rod is equipped with the crossbeam 41 in solid cylinder, the valve body tail
End is equipped with inlet opening 36；The front apron 37 for limiting the fore-stock is additionally provided on the side wall of the valve body.
The through-hole of the utricule tail end is connected with sleeve 5, and the rear mounting circular ring is set in the lateral wall of the sleeve simultaneously
It achieves a fixed connection with the sleeve, the through-hole of utricule tail end is equipped with back support rod 6, and the head end of the back support rod passes through described
The head end side wall of sleeve and the inside that the utricule is arranged in, the back support rod is additionally provided with for blocking holding for the inlet opening
Pressing plate 61, the head end of the back support rod are equipped with the slot 62 of strip, and the crossbeam is arranged in the slot, and crossbeam can
It is moved along the slot, the cunning in prismatic table shape for blocking the utricule tail end through-hole is additionally provided on the support rod
Block 63, the sliding block are arranged inside the utricule, and the bottom of the sleeve and the upper surface of sliding block are equipped with sheet rubber 64, institute
Center to the tail end for stating back support rod is arranged at the outside of the utricule；
The outside of the sleeve is equipped with the rear baffle 51 for facilitating back support rod to operate for providing fulcrum.
The u-bracket includes chassis 21 and the side stand 22 that chassis both ends are arranged in, and the end of the side stand is supported
The firmly ship wall of hull broken hole surrounding, the chassis are equipped with the through-hole passed through for back support rod tail end.The u-bracket is matched with
Retaining mechanism, the retaining mechanism include the external screw thread (not shown) being arranged on the latter half of side wall of the back support rod and with
The fixture nut 23 that external screw thread matches is symmetrically arranged with a pair of of handle 24 in the fixture nut.
Of the invention specifically used steps are as follows: under original state, as shown in figure 4, pushing back support rod 6 to arrive the limit forward
Position, bearing plate 61 resists the bottom of valve body 3 at this time, and sliding block 63 is in fore-stock 14 and the hinged position of after-poppet 15, preceding branch
The crossbeam of strut 4 is in the caudal end of slot, utricule strip at this time, convenient for placing.
When broken hole, which occurs, in hull needs leak stopping, in conjunction with shown in Fig. 1, Fig. 2 and Fig. 4, the utricule under original state is protruded into
Broken hole holds back support rod 6, and resists the similar movement that opens an umbrella of rear baffle 51(), along water (flow) direction by back support rod caudad
After drag, until the crossbeam of front end panel be in the front end of slot, bearing plate 61 is far from valve body at this time, the abutting sleeve 5 of sliding block 63, and
And under the supporting role of sliding block 63, fore-stock 14 and after-poppet 15 are strutted, and under the keeping out of front apron 37, fore-stock 14 is by boring
Shape becomes disc, and (1. since utricule is made of bracket and rubber cyst wall, and with the rotation of bracket, rubber cyst wall can be transported therewith
It moves without damaging；2. the length of suitable fore-stock, after-poppet, the position made may be selected by wired experiment
Under, fore-stock state in a vertical shape).
At this point, the inlet opening 36 of valve body 1 is unobstructed, since the pressure of water flow is bigger, and utricule inner hollow at this time, pressure
Power is smaller, therefore water flow can squeeze spool 34, make between spool and adjusting nut 23 occur water inlet space, at this time water flow constantly into
The inside for entering and thering is inlet opening to enter utricule, and with the continuous injection of water flow in utricule, utricule constantly struts to block
Broken hole (as depicted in figs. 1 and 2).
Along with utricule constantly strut, while at broken hole side wall extruding, the intracorporal inside water pressure of capsule be higher than outside
Hydraulic pressure, in the case where inside water pressure and spring 35 act on, adjusting nut 31 is realized in spool ejection is closed.
U-bracket is finally inserted in back support rod, using on back support rod external screw thread and fixture nut, handle will be entire
Device for plugging is fixed, and is in device for plugging under stable working condition.
By above mode, water-bag type lost circulation plug peculiar to vessel provided by the present invention, by utilizing front support rod, rear support
Bar adjusts the inner space of utricule, using the impact force of water flow at valve body and ship broken hole make water flow enter in utricule and by
Step struts utricule, cooperates sliding block to blocking at ship broken hole, and reaching reduces operation difficulty, realizes fast blockage and raising
The purpose of the safety coefficient of ship and ship's staff.
Above-described is only the preferred embodiment of water-bag type lost circulation plug peculiar to vessel disclosed in this invention, it is noted that
For those of ordinary skill in the art, without departing from the concept of the premise of the invention, several changes can also be made
Shape and improvement, these are all within the scope of protection of the present invention.
