Embodiment
Be illustrated in figure 1 as a kind ofly for the Pull breaking ualve on the filling machine, comprise air inlet nozzle 1, air inlet nozzle 1 forms a seal chamber with middle cover 3 and guide pin bushing 9; Middle cover 3, one end and air inlet nozzle 1 are threaded connection, the other end socket outlet nozzle 2; Outlet nozzle 2, outlet nozzle 2 forms seal chamber with middle cover 3 and guide pin bushing 9, and inside is provided with a spool 8; Guide pin bushing 9, guide pin bushing 9 are socketed in respectively on the outer wall of air inlet nozzle 1 and outlet nozzle 2 joints, and described guide pin bushing 9 inwalls are provided with annular groove, and the hole is installed in the annular groove of guide pin bushing 9 with back-up ring 16; Returnning spring 10 is arranged between air inlet nozzle 1 and the guide pin bushing 9, is used for when Pull breaking ualve is broken guide pin bushing 9 being resetted, and makes guide pin bushing 9 and middle cover 3 form seal chamber; At least one seal ring 19 is arranged between air inlet nozzle 1 and the middle cover 3, between guide pin bushing 9 and the air inlet nozzle 1, between guide pin bushing 9 and the outlet nozzle 2, between guide pin bushing 9 and the middle cover 3, between middle cover 3 and the outlet nozzle 2, be used for the close encapsulation cavity; Main spring 11 is arranged between spring seat 7 and the spacer shell 5, provides Pull breaking ualve to break required pull-off force; Spacer shell 5 is connected with middle cover with connecting sleeve 4 and is connected by Cock screw 15; Steel ball 14 is arranged in the circular hole of spring seat 7, and an end is stuck in the groove of outlet nozzle 2 outer walls, and the other end withstands on the spacer shell 5, and steel ball 14, main spring 11, spring seat 7 form a whole by shaft block ring 17 and spacer shell 5; Safety cover 6 is connected with spacer shell 5 by screw thread, and the surface of Pull breaking ualve is played a protective role; Spool 8 is arranged in the outlet nozzle 2, is used for preventing when Pull breaking ualve is broken the fluid reverse leakage; Compress Spring 12 is arranged between spool 8 and the valve core housing 13; Spacing back-up ring 18 is arranged in the air outlet hole of outlet nozzle 2, and valve core housing 13 is limited in the outlet nozzle 2.
During this Pull breaking ualve normal operation, fluid enters the air inlet nozzle 1 of Pull breaking ualve by high pressure hose, inlet hole on air inlet nozzle 1 enters middle cover 3 inner chambers, fluid enters outlet nozzle 2 fluid passages by outlet nozzle 2 left end pores, high pressure draught is pushed the spool 8 in outlet nozzle 2 passages open, and then fluid flows out Pull breaking ualve through the through hole on the valve core housing 13.
When the under tension of Pull breaking ualve two ends, power is delivered to power on the spring seat 7 by steel ball 14, spring seat 7 compression main springs 11, and outlet nozzle 2 moves right, and after steel ball 14 enters in the spacer shell 5 right side grooves, breaks away between outlet nozzle 2 and the Pull breaking ualve.Because outlet nozzle 2 moves right, this moment, guide pin bushing 9 moved right along air inlet nozzle 1 and outlet nozzle 2 outer surfaces under the spring-force driven dual of Returnning spring 10, seal ring 19 and middle cover 3 deadends of guide pin bushing 9 right-hand member outer walls form sealing state, block the high-pressure liquid that flows into from air inlet nozzle 1.After Pull breaking ualve is broken, outlet nozzle 2 pulls, when the pressure fluid reverse leakage, spool 8 is oppositely mobile under High Pressure, by being sealed and matched and the double seal of seal ring 5 with outlet nozzle 2 cambered surfaces, and form sealing state between the outlet nozzle 2, block the passage of outlet nozzle 2, thereby can prevent outlet nozzle end fluid generation reverse leakage.
After this Pull breaking ualve is broken; can be by safety cover 6 be applied left pressure to spacer shell 5; or apply certain pressure by frock to spacer shell 5; compression main spring 11; when the groove on outlet nozzle 2 surfaces aligns steel ball 14, remove the external force that acts on the spacer shell 5, spacer shell 5 moves to right under the effect of spring force; steel ball 14 is embedded in the groove on outlet nozzle 2 surfaces, and this moment, Pull breaking ualve can normally use again.
This Pull breaking ualve is by spring seat 7 compression main springs 11, make main spring 11 produce the size that pulling-out force is controlled in axial deformation, the pulling-out force of Pull breaking ualve can accurately be controlled, and can come the pulling-out force of Pull breaking ualve is regulated by the spring of replacing different-stiffness or the amount of deformation of Regulation spring.Main spring 11 provides axial elastic force in the Pull breaking ualve, and does not need to carry out precompressed, all adopts screw thread to connect between each parts, makes the assembling of Pull breaking ualve more convenient.
