Embodiment
As shown in Figure 1 and Figure 2, a kind of explosion-proof valve described in the utility model, comprise valve chest 1, spool mechanism 2, handle 3, in order to realize the object the utility model proposes, in described valve chest 1, be also provided with anti-explosion mechanism 4, this anti-explosion mechanism 4 comprises sealing glue 41, Returnning spring 42, gum cover 43, water inlet glue 44, and wherein gum cover 43 becomes the glue part of hollow structure, described water inlet glue 44 is set with two ends in Returnning spring 42 with sealing glue 41, and is set in gum cover 43 together with Returnning spring 42; The upper end of described sealing glue 41 is connected with the bottom of spool mechanism 2, and the bottom of described water inlet glue 44 is arranged at the water inlet port of valve chest 1 through gum cover 43.
For make between sealing glue 41 and spool mechanism 2 can be simply, connect reliably, as depicted in figs. 1 and 2, between sealing glue 41 and spool mechanism 2, be also provided with copper packing part 5, the central part of this copper packing part 5 has been made through hole 51, in the outside of copper packing part 5, make a circle groove 52, on this groove 52, be set with cushion rubber 6.Again as shown in Figure 1, this copper packing part 5 is arranged between sealing glue 41 and spool mechanism 2, plays and connects sealing glue 41 and spool mechanism 2, realizes the function of water guide.Described cushion rubber 6 mainly plays sealing and the sealing effect between copper packing part 5 and valve chest 1 inwall in copper packing part 5 peripheries, and the whole via through holes 51 of water are flowed in spool mechanism 2.
For described sealing glue 41 has scientific structure design, reasonable, simple feature, as shown in Figure 2, described sealing glue 41 connects top 411 and forms with four risers 413 of crosswise together with arranging that are between sealing bottom 412 by connecting top 411, sealing bottom 412 and being arranged at, and between riser 413 and riser 413, is also formed with tank hole 414.In like manner, as shown in Figure 2, the limited ring 443 of described water inlet glue 44 by socket top 441, trash rack bottom 442 and in the middle of being arranged at forms, and is wherein socketed top 441 and becomes hollow structure, and this hollow structure is connected with trash rack bottom 442.
For make into water glue 44 with can science between gum cover 43, together with rationally assembling, as shown in Figure 1, gum cover 43 bottoms of described hollow structure also make at the bottom of limited location hole 431, and described water inlet glue 44 is trash rack bottom 442 to be piercing in gum cover 43 belows, bottoms to arrange by its limited ring 443 and 431 mutually spacing assemblings at the bottom of spacing hole.Simultaneously, in order to guarantee the close property of wedge of assembling between gum cover 43 and valve chest 1, as depicted in figs. 1 and 2, the top margin of the gum cover 43 of described hollow structure is also made limited location circle 432, in described valve chest 1, make accordingly the step 11 of the setting-in that matches with this position limit cycle 432, and in the water inlet port of valve chest 1, also make accordingly for the accommodating lumen pore 12 in trash rack bottom 442, between step 11 and lumen pore 12, make for the accommodating cylindrical cavity groove of gum cover 43, described gum cover 43 is by its position limit cycle 432 and the mutually spacing assembling of step 11, so that whole gum cover 43 can positioningly be installed in cylindrical cavity groove.Meanwhile, in order to guarantee the sealing of intersection between the cylindrical cavity groove of gum cover 43 bottoms and lumen pore 12, ，Gai intersection is also provided with packing ring 9 as depicted in figs. 1 and 2.
For fear of the larger impurity of volume in water, enter into valve chest 1, as depicted in figs. 1 and 2, at the mouth end of the lumen pore 12 of valve chest 1, be also separately installed with filtering net plate 7 and for clamping the jump ring 8 of filtering net plate 7.
The working principle of anti-explosion mechanism 4 of the present utility model is roughly such: as shown in Figure 1, water enters from the lumen pore 12 of valve chest 1, flow through into water glue 44, due to Returnning spring 42 effects, between water inlet glue 44 and sealing glue 41, leave gap, water enters into gum cover 43 from gap, through tank hole 414 and through hole 51, enter into spool mechanism 2, from the water outlet port of valve chest 1, flows out.When hydraulic pressure increases, the pressure of water has overcome the active force of Returnning spring 42, make into water glue 44 jack-up upwards, the sealing bottom 412 of sealing glue 41 enters into into the cavity on the socket top 441 of water glue 44, the gap of leaving between water inlet glue 44 and sealing glue 41 is stopped, water is dammed, thereby play explosion-proof effect.When hydraulic pressure recovers normal, under Returnning spring 42 effects, open in the gap of leaving between water inlet glue 44 and sealing glue 41, and water again can proper flow.
