Description
Technical field
The present invention relates to a kind of valve, the explosion-proof valve of a kind of quick pressure release.
Background technology
After mist of oil in crank case of internal combustion engine causes detonation, high temperature bluster can be produced.To this end, be arranged on the casing of crankcase by explosion-proof valve, when there is pinking, explosion-proof valve is opened rapidly, high temperature bluster carries out pressure release, the flame that goes out, cooling through valve body, close explosion-proof valve the most immediately, and keep sealing, in case fresh air causes secondary detonation in entering crankcase.
Summary of the invention
Defect for prior art, it is provided that the explosion-proof valve of a kind of quick pressure release.
The present invention is realized by following proposal:
A kind of explosion-proof valve, is provided with flame-retardant device in valve pocket described in the valve block fix the valve gap being connected and being formed valve pocket with valve seat including valve seat, being pressed on valve seat by the spring in valve pocket.
The plurality of flame-resistant sheet is perpendicular to valve seat.
Described flame-retardant device includes the flame-resistant sheet that multiple lift direction along valve block is arranged, gap between flame-resistant sheet is through in the lift direction along valve block, described flame-retardant device also includes inner support circle, outer support circle, inner support circle and or outer support circle be provided with equally distributed through hole, described inside and outside bracing ring is expanded metals structure or steel wire.
The plurality of flame-resistant sheet, each two flame-resistant sheet is superposed to one group；One of them flame-resistant sheet is concavo-convex flame-resistant sheet, and another flame-resistant sheet is concavo-convex flame-resistant sheet or is plain film；Multiple salient point and or concave point are distributed on described concavo-convex flame-resistant sheet.
Salient point on described concavo-convex flame-resistant sheet and concave point are two kinds, a kind of for controlling gap convex-concave point, control gap convex-concave point and contact with another flame-resistant sheet；Another kind of is time delay convex-concave point, and time delay convex-concave point contacts with another flame-resistant sheet or do not contacts.
The invention have the benefit that
1. the explosion-proof valve of a kind of quick pressure release of the present invention can reach maximum pressure release within the shortest opening time, and extinguished completely in explosion-proof valve by flame simultaneously, makes to go out flame more rapidly completely.
2. the flame-resistant sheet of the explosion-proof valve of a kind of quick pressure release of the present invention uses the mode of vertical arrangement, it it is up/down perforation between flame-resistant sheet, i.e. flame-retardant device is through in the lift direction along valve block, this just makes a high temperature bluster lift when valve block has just been opened or opened the least just can be distributed to top along flame-resistant sheet passage from bottom to top from bottom, extend through in whole flame-retardant device, be conducive to occurring moment to reach the pressure release of maximum within the shortest opening time in blast, and flame is extinguished completely in explosion-proof valve, make to go out flame more rapidly completely. simultaneously；The countless clearance channel that flame is formed between the flame-resistant sheet of 360 ° of distributions in valve pocket, these passages due on flame-resistant sheet the salient point of regular array in repeatedly bending path, air-flow and flame elapsed time and distance is extended with this, make flame-resistant sheet fully absorb heat, and reduce molecular activity by wall collision effect in the process and reach to go out the purpose of flame.
Accompanying drawing explanation
Fig. 1 is the anti-explosion valve structure schematic diagram of a kind of quick pressure release of the present invention.
Detailed description of the invention
Below in conjunction with Fig. 1, the preferred embodiment of the invention is further illustrated:
As shown in Fig. 1, explosion-proof valve of the present invention, including discoidal valve seat 2, valve gap 11, valve gap 11 and valve seat 2 form valve pocket, are evenly distributed in some guide pin bushings 9 between valve gap 11 and valve seat 2, and the length of guide pin bushing 9 determines the height of valve pocket；Valve gap 11 is fixed with valve seat 2 by bolt 6, pad 5 and is connected, and the screw rod of bolt 6 is arranged in bolt sleeve 4.Being provided with valve block 8, spring 7 in valve pocket, valve block 8 is pressed on valve seat 2 by spring 7；Sealed by " O " RunddichtringO 1 between valve block 8 and valve seat 2, make valve keep sealing under the thrust effect of spring 7；Narrow and small gap is left, to limit the valve block 8 moving direction along guide pin bushing 9 between guide pin bushing 9 and valve block 8；Spring 7 is circular cone compression spring；Flame-retardant device 3 is set in valve pocket.
Flame-retardant device 3 includes inner support circle 10, outer support circle 12, multiple flame-resistant sheet；Each flame-resistant sheet is along the arranged radially of valve seat 2；Flame-resistant sheet is arranged along the lift direction of valve block, and making the gap between flame-resistant sheet is through in the lift direction along valve block, arranges for being perpendicular to valve seat 2.Two bracing rings 10,12 form toroidal cavity, and multiple flame-resistant sheets are the most evenly distributed, are placed in this toroidal cavity；Bracing ring 10,12 is as the fixing and framework of support flame-resistant sheet.Bracing ring 10,12 is provided with equally distributed through hole, has dispersed flame and effectively controls the characteristic of air current flow；Bracing ring 10,12 can use expanded metals structure, such as circular hole net or steel wire.The biggest increase flow resistance in the case of, the cooling capacity of flame-resistant sheet, and the intensity having had can be better profited from, it is ensured that will not produce at explosion time affects the deformation of performance.
The flame-resistant sheet of the explosion-proof valve of a kind of quick pressure release of the present invention uses the mode of vertical arrangement, it it is up/down perforation between flame-resistant sheet, i.e. flame-retardant device is through in the lift direction along valve block, this just makes a high temperature bluster lift when valve block has just been opened or opened the least just can be distributed to top along flame-resistant sheet passage from bottom to top from bottom, extend through in whole flame-retardant device, be conducive to occurring moment to reach the pressure release of maximum within the shortest opening time in blast, and flame is extinguished completely in explosion-proof valve, make to go out flame more rapidly completely. simultaneously；The countless clearance channel that flame is formed between the flame-resistant sheet of 360 ° of distributions in valve pocket, these passages due on flame-resistant sheet the salient point of regular array in repeatedly bending path, air-flow and flame elapsed time and distance is extended with this, make flame-resistant sheet fully absorb heat, and reduce molecular activity by wall collision effect in the process and reach to go out the purpose of flame.
Although technical scheme having been done the most detailed elaboration and having enumerated; it is to be understood that; to those skilled in the art; above-described embodiment is made amendment or uses the replacement scheme of equivalent; this is apparent to those skilled in the art; these modifications or improvements without departing from theon the basis of the spirit of the present invention, belong to the scope of protection of present invention.
