Abstract
The utility model relates to an emergency disengaging device of a liquid transferring duct used on an oil transferring arm, which comprises cone valves. The inner parts of two butt-jointed pipe-shaped the valve seats for the cone valves are respectively provided with a cone valve unit with the same structure; the inner parts of two upper cone valves are respectively provided with a cone valve core, a guide spring seat and a reset spring; the outer ends of the two butt-jointed valve seats with flanges for the cone valves are provided with a three-slice snap ring with a V-shaped clamping groove, wherein, every two of the three slices are hinged with each other. The snap ring is also orderly provided with a power separating mechanism of the cone valve, wherein, the power separating mechanism is composed of an oil cylinder, a connecting rod of a piston, a shearing swing rod, and a safe shear pin of the snap ring. The utility model has the advantages of simple structure, convenient operation, quick shut down, low cost, etc.
Description
The utility model belongs to the pipeline road technical field, specifically a kind of fire protection equipment that is arranged on the overhanging terminal flange-interface of oil-feeding arm.
The fire safety of petroleum chemical industry is vital problem.With the oil transport pipeline is example, the oil-feeding arm that is connected with transport pipe and being subjected between the oil pipe to flange docks, and no segregating unit when fire or other urgency take place, can't break away from, and is unfavorable for control and eliminates dangerous situation.At present, a kind of disengaging structure of Cai Yonging is two ball valve forms in the world, although the more preceding a kind of bigger improvement that has of this linkage structure, can in time break away from when dangerous situation occurring, but the involving great expense of its equipment, closing velocity is still rapid inadequately, and sealability is bad, the operating mechanism complexity.
The purpose of this utility model provides a kind of cone valve type structure and adopts hydraulic operated liquid-transport pipe-line emergency separating device.
The purpose of this utility model is achieved in that it comprises two cone valves, it is characterized in that in the pipeline shape cone valve valve seat of two butt joints, being respectively arranged with a cone valve unit that structure is identical, in two cone valve unit, be respectively arranged with the conical surface spool of the mutual apical grafting of its cone top part, respectively be provided with one along the compressed Returnning spring of guide spring seat in the awl bottom of conical surface spool; Be provided with one two outer ends of pipeline shape cone valve valve seats that have chimb and a butt joint by mutually hinged and have three snap rings of V-arrangement draw-in groove in twos, on snap ring, also be disposed with the cone valve power extractor structure that the oil cylinder, piston rod, shearing fork and the snap ring safety shear pin that separate snap ring formed.On the chimb of two pipeline shape cone valve valve seat outer ends that connect, also be evenly distributed with pressure spring in addition.When oil-feeding arm normally sent combustable liquid, then liquid was by the cone valve of two unlatchings; In case operation field generation fire or other emergency situation, as long as the hydraulic handle of pulling control system, under the effect of pressure oil, the piston rod of power cylinder just stretches out, promote to shear fork simultaneously and cut off safe shear pin, three snap rings also are compressed spring simultaneously and push open, can be disconnected from each other under the effect of Returnning spring separately by two flange plate being mediated, thus simultaneously conical surface spool is pressed against on separately the right angle valve port, then two cone valves cut out and prevented the excessive of combustable liquid in the pipeline.
The utlity model has simple in structure, easy to operate, in case when operation field generation fire or other emergency situation, can realize the automatic disengaging of conveyance conduit in several seconds, therefore break away from rapidly, but also have characteristics such as cost is low, good seal performance, applied range.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation that partly cuts open of the present utility model
Fig. 2 is snap ring of the present utility model and detachment dynamic mechanism structure for amplifying schematic representation
Shown in Fig. 1-2,1,5 is pipeline shape cone valve valve seat two butt joints and that have right angle valve port and chimb, in this valve seat 1,5, respectively be provided with the cone valve unit of a same structure, in two cone valve unit, be respectively arranged with the conical surface spool 2 of the mutual apical grafting of its cone top part, respectively be provided with in the awl of conical surface spool 2 bottom one along tubular guidewire to spring seat 4 compressed Returnning springs 3, between two pipeline shape cone valve valve seats that connect, also be equipped with seal ring 6.Be provided with one by mutually hinged and have three snap rings 8 of V-arrangement draw-in groove in twos at the outer end jointing of the pipeline shape cone valve valve seat 1,5 of two butt joints, on snap ring 8, also be disposed with the oil cylinder 9, the piston rod 10 that separate snap ring, shear the cone valve power extractor structure that fork 11 and snap ring safety shear pin 12 are formed.An also even distribution 6-8 pressure spring 7 on the chimb of two pipeline shape cone valve valve seat outer ends that connect in addition.When the oil-feeding arm that is arranged on port and pier is normally carried combustable liquid, then liquid is by the cone valve inner space of two unlatchings, in case operation field generation fire or other emergency situation, very important person when control in the hydraulic handle of pulling control system, under the effect of pressure oil, the piston rod of power cylinder 9 just stretches out, promote to shear fork 11 simultaneously and cut off safe shear pin 12, three snap rings 8 also are compressed spring 7 simultaneously and push open, can be disconnected from each other under the effect of Returnning spring separately by two flange plate being mediated, simultaneously conical surface spool is pressed against on the right angle valve port separately, can realize that in seconds two cone valves cut out, thereby prevented the excessive of the interior combustable liquid of pipeline, elimination has also been controlled fire, has guaranteed the safety of harbour and boats and ships.
