24.2 form the compressing to 15 thick column of cylinder, 15.2 outer end face；It is equipped with inclined-plane 15.4 in 15.1 side of slide plate of cylinder 15.
The present invention use process is as follows：
The connecting tube A2 of the application assembled and connecting tube B9 are connected to the discharging of liquid material conveyance conduit by short circuit
On mouth pipeline, it is then turned on equipment normal operation, raw material liq enters mobile valve rod 19 by the pore of connecting tube A2 at this time
The pore of 17 and connecting tube B9 of perforation is flowed；Equipment passes through pulling when there is interface loosening or pipeline burst problem
At this moment the becket bridle 7 of drawstring 6 moves the slide plate 15.1 of cylinder 15 simultaneously outside control-rod 14 by the shallow slot 28.5 of control-rod 14 via protrusion
28.3 slide into deep trouth 28.1, and further the first outer retraction perforation 22 after moving some loosening of the buttress shaft 15.3 of acquisition cylinder 15, at this moment justifies
The buttress shaft 15.3 of column 15 loses the control to 26 the other end face of valve pipe, and the expanding ring 20 that spring 10 heads on mobile valve rod 19 is outside
It is mobile, while the perforation 17 of mobile valve rod 19 deviates the pore of connecting tube B9 and connecting tube A2, that is, moves valve rod 19 by connecting tube
The pore closing of the pore and connecting tube A2 of B9, obtains preferable plugging effect, liquid just no longer flows；At this moment pipe can be repaired
Road, the becket bridle 7 of drawstring 6 can be placed on by the present invention can and locate conveniently, occur emergent pulling when dangerous situation convenient for pipeline.
In actual use, can lead sealing be set in the suitable position of 14 tablet 27 of control-rod, to prevent staff from arbitrarily opening
It opens；The casing of protection can be also set outside spring 10.
Part not in the detailed description of the invention is the prior art.
