Embodiment
Below in conjunction with accompanying drawing the utility model is made a detailed description:
In order to overcome the deficiencies in the prior art, the utility model provides a kind of Pull breaking ualve at this, as shown in Figure 1, stupid device comprises air inlet valve body 1, be respectively arranged with in the cylindrical both sides of air inlet valve body 1 two blocking-up plugs 6 and blocking-up obturating plug 4 and with both work in coordination sealing gasket 7, pinch roller 16, pin 17 and the Returnning spring 5 of work.Between being threaded of blocking-up obturating plug 4 and air inlet valve body 1, be provided with copper sealing gasket I 3, the other end be provided with middle cover 10 and outlet nozzle 14 and and middle cover the work in coordination collar 11, limit spring 12, Stainless Steel Ball 18 and the air inlet valve body 1 of work and the copper sealing gasket II 9 between the middle cover 10, also have and outlet nozzle 14 work in coordination guard shield 19, circlip 21, guard shield packing ring 13, nonreturn valve core 20 and the spring seat 23 of work and the gas outlet valve spring 22 that cooperates nonreturn valve core 20 to work.Be provided with work in coordination 2 spring energy-storage circles 2 and being used to of work of outlet nozzle 14 cylindricals in the inside cavity of air inlet valve body 1 and locate blocking-up plug 6 the drainages cover 15 that flows to of boot media and the wavy spring 8 of supporting drainage cover 15 simultaneously, wherein and bottom and all be provided with spring energy-storage circle 2 between the fitted seal of outlet nozzle 14 in the top of air inlet valve body 1 inside.
The intake interface screw thread bottom of air inlet valve body 1 is provided with 2 medium channel 24 and blocking-up plug sealed cavity passage 26, be provided with a trapezoidal positioning through hole 25 that overflows flowing medium that is used to orient the valve 14 and the valve inner of draining in valve body middle and lower part near inlet end, at main medium channel 30 and 8 assist medium passages 28 that flow to that the center and the hole wall of outlet nozzle 14 is provided with 1 outflow, also have the cooperation hole wall of drainage cover 15 to be provided with 10 medium channels that flow to 29 and 2 blocking-up plug positioning holes 27.
Described Pull breaking ualve is broken the automatic sealing device that separates the two ends, back and is comprised respectively under normal or improper situation:
A, inlet end: the moment that Pull breaking ualve is being broken, blocking-up plug 6 can promote to move forward the conical surface that makes sealing gasket 7 with the pinch roller 16 of its work of working in coordination fast with sealing gasket 7 because of the disengaging of outlet nozzle and contact the formation sealing fully with the sealing tapering that cavity inside is filled in the valve body blocking-up under the active force of the automatic elongation of Returnning spring 5 meetings, fluid is closed in the air inlet valve inner;
B, outlet side: the moment that Pull breaking ualve is being broken, fluid in the pipe can cause fluid to flow in the opposite direction because of low inside and high outside pressure reduction characteristics, move forward front end and the formation contact seal of outlet nozzle 14 internal cavities edges that makes nonreturn valve core 20 in these moment nonreturn valve core 20 meetings in the effect of gas outlet valve spring 22 and flowing medium, fluid is closed in air inlet valve body 1 inside.One complete, the working procedure of intact Pull breaking ualve (emergency shutoff device) is: working medium at first enters blocking-up plug 6 internal cavities passages by the flow through passage of both sides, screw thread bottom of import tapped hole passage, by the cooperating of blocking-up plug 6 with Returnning spring 5 and drainage cover 15 and outlet nozzle 14,12 medium channels that working medium overlaps 15 surfaces through drainage enter the main outflow medium channel of outlet nozzle inside again through 8 medium channels of outlet nozzle 14, fluid promotes nonreturn valve core 20 and moves through gas outlet valve spring 22 and enter outlet tapped hole passage and flow out Pull breaking ualve and enter storage device simultaneously.This Pull breaking ualve can be used for abominable working environment uses down such as low temperature (low pressure) for a long time.When bearing certain pulling force, Pull breaking ualve can automatic disconnection, prevents to break the loading and unloading pipe and cause leakages/seepage because of car or operator's mistake/the forget operation of sauntering of being not intended to of loading and unloading tank car, prevents unexpected generation and causes the bigger harm and the loss of personnel and equipment.This valve break or come off after need manual reset and can repeat to break use; Valve has: two kinds of Placements of endosiphuncular tube screw thread and interior straight pipe thread; Working principle is described as: the bypass formula that leaks is controlled the sealing Pull breaking ualve automatically.
