In order to overcome above-mentioned defect and the deficiency of prior art, the second object of the present invention is to provide a kind of powder storehouse, comprise Cang Ding, described Cang Ding is provided with top, storehouse flange, described powder storehouse also comprises any one powder storehouse pressure relief valve above-mentioned, and Flange joint is pushed up by safety flange and described storehouse in the bottom of described powder storehouse pressure security valve body.
Powder storehouse of the present invention pressure relief valve can realize valve gap parking position accuracy by increasing guide ring, effectively prevents valve gap from opening rear run-off the straight at safety valve and causing the inaccurate defect that resets.
Accompanying drawing explanation
Fig. 1 is the example structure schematic diagram of powder storehouse of the present invention pressure relief valve.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, powder storehouse pressure relief valve embodiment of the present invention comprises: valve gap 1, valve body, guide ring 2; Wherein, valve gap 1 is arranged on the top of valve body, and can arrange sealing gasket 10 between valve gap 1 and valve body; Guide ring 2 is positioned at valve inner and is connected with valve gap 1; The outer wall of guide ring 2 matches with the inwall of valve body, can move up and down at valve inner.During specific operation, valve gap 1 can be connected by sealing gasket 10 with valve body, to strengthen sealing effect.
Preferably, in order to strengthen guide effect, namely the increase outer wall of guide ring 2 and the inwall of valve body coordinate the area of (contact), guide ring 2 can be hollow cylindrical structure, and certainly, the height of cylinder is larger, the area of contact of the two is also larger, and guide effect is also better.
Preferably, in order to avoid the lifting height of valve gap 1 is excessive, fly out and cause danger, above-mentioned powder storehouse pressure relief valve can also comprise: the lifting height for limiting valve cap 1 is less than the bounding means 4 of predeterminable range, and bounding means 4 is connected with guide ring 2 and is positioned at the below of guide ring 2.
During specific operation, bounding means 4 can comprise: connecting rod 41 and pin 43; Connecting rod 41 connects guide ring 2 and pin 43 respectively, as welded with pin 43 with guide ring 2 respectively; Pin 43 is positioned at the below of valve body bottom, and the length of pin 43 is greater than the ultimate range of valve body bottom point-to-point transmission.Like this, namely the position that pin 43 rises to adjacent valve body bottom is stopped by valve body bottom, the structure of certain bounding means 4 is as shown in Figure 1 that one exemplifies, various structures form can be had as required, as when the height of guide ring 2 is enough, bounding means 4 can only comprise pin 43, and namely connecting rod 41 can omit.
During specific operation, connecting rod 41 can be connected with valve gap 1 by screw rod 11; Because connecting rod 41 is connected with guide ring 2, the annexation between guide ring 2 and valve gap 1 can be achieved by screw rod 11.The shape of connecting rod 41 can be arranged according to actual needs, and as shown in Figure 1, connecting rod 41 can form tuning-fork type structure with screw rod 11 entirety.
Preferably, in order to effectively prevent rainwater weather from causing powder to lump the defect causing safety valve to lose efficacy, above-mentioned powder storehouse pressure relief valve can also comprise: protective cover 5 and protective cover supporting rib 6, and protective cover 5 is connected with valve body by protective cover supporting rib 6.More preferably, in order to more protection lid supporting rib 6 is connected with valve body, protective cover supporting rib 6 can by being connected with valve body with larynx hoop 3.Certainly, protective cover supporting rib 6 and valve body Placement can have multiple, arrange according to actual needs.
During specific operation, above-mentioned powder storehouse pressure relief valve is when being applied to powder storehouse, and the storehouse that its valve body bottom can be pushed up on 9 by safety flange 7 and storehouse is pushed up flange 8 and is connected, like this, the inconvenience can avoiding the inner mounting safety valve from powder storehouse is set by safety flange 7, decreases the difficulty of installing and safeguarding; Meanwhile, powder storehouse pressure relief valve pushes up flange 8 by safety flange 7 and storehouse and pushes up 9 with storehouse and be connected, and adds valve gap 1 and storehouse and pushes up distance H between 9, effectively prevent valve body and is overflowed material and bury and the defect that causes safety valve to lose efficacy.
The mechanism of above-mentioned powder storehouse pressure relief valve is summarized as follows: when the pressure in powder storehouse is lower than setting value, and between valve gap 1 and valve body, sealing gasket 10 ensure that the seal request that powder storehouse works; When the pressure in powder storehouse exceedes setting value, valve gap 1 moves upward together with guide ring 2 and bounding means 4, is mixed with the gas of powder by promoting gap pressure release, pressure excessive in release powder storehouse; When lifting height exceedes certain distance, limiting valve cap 1 continues to raise, in order to avoid valve gap flies out cause danger by bounding means 4; Along with the decline of storehouse internal pressure; valve gap 1 is automatically reset by bounding means 4 under the effect of guide ring 2; stop exhaust pressure relief; guide ring 2 plays guiding and location in decline process; valve gap is effectively prevented to tilt to cause the inaccurate problem that resets; thus effectively protect powder storehouse safety, ensure that carrying out smoothly of production.
Be understandable that; in Fig. 1, guide ring 2 adopts hollow cylindrical structure to be only in the mode realizing Anti-inclining to exemplify; can change the shape of guide ring 2 during specific operation as required, the guide ring namely avoiding valve gap 1 to tilt with other difformities all belongs within protection scope of the present invention.
Various embodiments of the present invention can realize valve gap parking position accuracy by increasing guide ring, effectively prevent valve gap from opening rear run-off the straight at safety valve and causing resetting inaccurate defect; Preferably, effectively prevent rainwater weather cause powder to lump and then the problem that causes safety valve to lose efficacy by increasing protective cover, safe and reliable; Safety valve and Cang Ding take flange connection, decrease the difficulty of installing and safeguarding, easily safeguard, add simultaneously valve push up as relief opening and storehouse between height, effectively prevent valve body to be overflowed material and bury and cause safety valve to block the phenomenon of inefficacy, overall structure is simple, and cost is low.
These are only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
