Embodiment
Below in conjunction with accompanying drawing detailed description is made in invention:
The present invention provides a kind of Pull breaking ualve; Shown in Fig. 1-4: include the valve block A101 and the valve block B102 that set up relatively; For breaking district 120, it is connected said valve block A101 and valve block B102 the place and all has internal thread between valve block A101 and the valve block B102.In Pull breaking ualve of the present invention, also comprise being provided with first joint 103, second joint 104, wherein first joint is connected with valve block A101, and second joint 104 is connected with valve block B102.Pull breaking ualve of the present invention can apply on the LNG filling machine, is fixedly connected with liquid feeding base on the liquid filler through first joint 103,104 realizations of second joint and flexible pipe.First joint 103 of this moment, second joint 104 all have outside thread, and first joint 103 is connected with valve block A101 internal thread through outside thread so, and second joint 104 passes through outside thread and is connected with valve block B102 internal thread.
Wherein the inside of valve block A101 and valve block B102 constitutes the passage that has taper respectively.Because valve block A101 and valve block B102 set up relatively, the cone shape hole 110 in valve block A101 and valve block B102 also is to exist relatively so.Be provided with the spool A105 and the spool B106 that valve core case 107 and valve rod 108 are made up of in valve block A101, valve block B102 inside this moment.The valve rod 108 that spool A105 and spool B106 are corresponding is middle parts of passing the other end of valve block A101 and valve block B102, and on the valve rod that passes 108, is provided with collar 109, is used to limit valve rod 108 and in valve block A101 and valve block B102, moves.Can know that by figure the valve rod 108 that spool A105 under the normal condition and spool B106 are corresponding is to holding state.
As shown in the figure, be distributed with a plurality of through holes 111 on every side at valve block A101 and the corresponding cone shape hole 110 of valve block B102.Wherein also be provided with pulling ring 112 on the valve block B103; Pulling ring 1 flexibly connects with clamp 113; Wherein clamp 113 the other ends are the connecting end 114 that has the inclined-plane; This end snaps onto on the valve block A101, and the intermediate portion of clamp 113 is the convex portion 121 that is stuck on the valve block B102 periphery, and its medi-spring 115 is stuck between valve block A101 and the pulling ring 112.In LNG aerating using process, when the LNG filling machine after aerating is accomplished because special circumstances, the liquid feeding rifle does not leave car body; Automobile starting leaves, and very big power is passed on the flexible pipe, breaks split plot 120 on this moment and the Pull breaking ualve that flexible pipe links to each other; Yielding and rupture under the effect of power, post-rift Pull breaking ualve still exists huge pressure in the pipeline at its two ends; Wherein the valve rod top of the top valve stem of spool A and spool B no longer holds, and under pressure, two spools all move to the fracture port place; Wherein spool A under high pressure breaks away from restriction and fits with the cone shape hole inwall in the valve body A101, seals up the liquid feeding part of pipeline.In like manner, spool B under high pressure breaks away from restriction and fits with the cone shape hole inwall in the valve body B102, avoids the interior liquid of pipeline to spill and hurts sb.'s feelings.
Said first joint 103, second joint 104 have a ring-type projection 117.
Also comprise and be provided with outer cover 116; The valve block A101 and the valve block B102 of Pull breaking ualve intermediate portion are covered; Said outer cover 116 two ends just are positioned at ring-type projection 117 places of first joint 103, second joint 104; Outer cover 116 can play a protective role, and such as playing the effect of protecting Pull breaking ualve inside self and protecting the effect of LNG to operator's injury, in addition outer cover 116 can also play decorating action.And be provided with at packing ring 118 at first joint 103, second joint, 10 places.
Through Pull breaking ualve of the present invention have simple in structure, can use repeatedly, easy to install, with low cost, airtight performance is good; Pull breaking ualve of the present invention can use in the environment of ultralow temperature high pressure, is suitable for applying on the LNG liquid filler, and Pull breaking ualve according to the invention adopts the design of little leakage formula, makes to break the back sealing load and can reduce gradually; Pull breaking ualve of the present invention adopts the outer cover design can avoid the liquid splash in the pipeline, and human body is damaged; Adopt the outer cover design also to have the profile beautiful decoration; Guarantee the safe in utilization of LNG liquid filler, be beneficial to popularization, normal life cycle is long; Can reduce maintenance cost, sealability is stable, long service life.
