Embodiment
See the accompanying drawing that the embodiment of the present invention is shown, hereafter in more detail the present invention will be described.But the present invention can realize in many different forms, and should not be construed as by the restriction in the embodiment of this proposition.On the contrary, it is abundant and complete open in order to reach for proposing these embodiments, and makes those skilled in the art understand scope of the present invention completely.In these accompanying drawings, for clarity sake, may be exaggerated size and the relative size in layer and region.
The invention provides a kind of explosion-proof end cover, be applicable to inflammable and explosive, need carry in the chamber resettling of larger pressure, the present invention's transformation and technologic transformation by structurally transforming explosion-proof end cover, on material, this explosion-proof terminal is had, and intensity is large, easy to make, low cost and other advantages.
With reference to Fig. 1-2, explosion-proof end cover includes an end cap body 1, and end cap body 1 is installed to one end on target cavity chamber in hollowing out shape, forms a columniform cavern part 105; The present invention by cutouts on end cap body, thus is conducive to the weight reducing explosion-proof end cover, is conducive to saving raw material, reducing costs.
In the present embodiment, be provided with some stiffening ribs 101 in cavern part 105, some stiffening ribs 101 are arranged along the radial direction of described cavern part 105, and some stiffening ribs 101 enclose circumference around the center one of cavern part 105 is uniformly distributed; One end of some stiffening ribs 101 is connected on the madial wall of cavern part 105, and the core that the other end of some stiffening ribs 101 is pooled to cavern part 105 forms a solid section 102; One side of stiffening rib 101 is also connected on the end face of cavern part 105; Wherein, arranging number and can adjusting as the case may be of stiffening rib 101, such as, is evenly equipped with six stiffening ribs 101 in the present embodiment in cavern part 105.The present invention by arranging some stiffening ribs 101 in cavern part 105, thus strengthens the intensity of explosion-proof end cover, and some stiffening ribs 101 are arranged radially, further strengthen the intensity of explosion-proof end cover.
In the present embodiment, the exterior edge face of solid section 102 is provided with a depressed part 1021, depressed part 1021 can one be cylindrical or conical etc., and concrete shape and the concrete size of depressed part 1021 all can design as the case may be, are not restricted herein.Because some stiffening ribs 101 collect the solid section 102 linking together and intersect to form, solid section 102 is thicker, and in injection moulding process, enter thick portion even, therefore stress concentrates on solid section 102; After long-time, the stress slow release in solid section 102, makes solid section 102 occur seminess, thus causes the liquid in chamber to ooze out from cracks; The present invention, by forming a depressed part on the end face of solid section 102, plays dispersive stress, prevents the effect that stress is concentrated, thus avoids phenomenon explosion-proof end cover occurring crackle.
In the present embodiment, the outer side wall that end cap body 1 is installed to one end on target chamber is provided with screw thread 103, and this end cap body 1 is installed on target chamber by screw thread; The end face of end cap body 1 target chamber is dorsad provided with a hexagonal hole 104, and in time being installed on target chamber by explosion-proof end cover, explosion-proof end cover is installed on target chamber by hexagonal hole 104 by setting tool.
In the present embodiment, explosion-proof end cover adopts the direct molding and forming of plastics, and end cap body 1 and stiffening rib 101 are one-body molded; Wherein, explosion-proof end cover adopts the PPS(polyphenylene sulfide of 60%) the GF(glass fibre of+40%) make, and add stabilizer wherein, and the ratio of PPS and stabilizer is 25:1.The present invention adopts above-mentioned material molding and forming to obtain explosion-proof end cover, makes this explosion-proof end cover have higher intensity.
Explosion-proof end cover adopts molding and forming to make, plastics in injection machine melting and be injected into corresponding die for molding obtain explosion-proof end cover, 4th district are divided in the cylinder that shoots material of wherein injection machine, the outlet of cylinder of shooting material is provided with nozzle, Mold Temperatures set on nozzle is 300 DEG C, and the temperature starting tactic 4th district backward from nozzle is set as 320 DEG C, 315 DEG C, 310 DEG C, 290 DEG C respectively.The present invention by carrying out segment design in injection machine injection molding cavity from end to the mold temperature of nozzle, thus prevents plastics melt too early and shunt; Temperature setting is too low, and plastics can not melt completely, and the interiors of products produced can not merge completely, and product easily ftractures.; Temperature setting is too high, causes plastics, and institute's production product performance decline, and do not reach.The present invention by above-mentioned technologic change, thus ensure that the explosion-proof end cover of molding and forming has higher intensity.
The present invention adopts explosion-proof end cover made of plastic, replaces metal explosion-proof end cover of the prior art, and its structure is light, and cost is lower, and can directly molding and forming, easy to make; Meanwhile, the present invention passes through the improvement to plastics, and to the structural improvement of explosion-proof end cover, the explosion-proof end cover that these plastics made are made has higher intensity simultaneously, larger pressure can be carried, and can be explosion-proof, be applicable to inflammable and explosive, need carry in the chamber resettling of larger pressure.
Because those skilled in the art should be understood that the present invention can not depart from the spirit or scope of itself with many other concrete forms realizations.Although described case study on implementation of the present invention, the present invention should be understood and should not be restricted to these embodiments, within the spirit and scope of the present invention that those skilled in the art can define as appended claims, make change and amendment.
