The jerking mechanism explosion discharge valve having the self-locking function provided by the utility model can implement automatic pressure relief and automatic resetting seal, accordingly, the changing and the maintenance of the parts can not be performed by the manual work, and the using of the utility model is convenient.
Description
Technical field
The utility model relates to a kind of jerking movement mechanism explosion-released valve, particularly a kind of jerking movement mechanism explosion-released valve with auto-lock function.
Background technique
Traditional explosion-released valve is when the system pressure superpressure, the explosion rupture of diaphragm, and the moment pressure release is finished, and the explosion diaphragm can only disposablely use, and needs artificial the replacing when reusing, and therefore uses and safeguard very inconvenience.
The model utility content
Technical problem to be solved in the utility model provides a kind of jerking movement mechanism explosion-released valve with auto-lock function, and it can realize need not artificial the replacing and maintenance, and easy to use.
For solveing the technical problem, the utility model provides a kind of jerking movement mechanism explosion-released valve with auto-lock function, it is characterized in that, it comprises flange, first block, first connecting rod, gland, second connecting rod, be wrenched spring, starting bar, channel bar, second block, the jerking movement spring, striking plate, the 3rd block and valve body, flange, gland and valve body form a Seal cage, striking plate is positioned on the inboard of valve body, striking plate is connected with an end of jerking movement spring, the other end of jerking movement spring is connected with the 3rd block, one end of first connecting rod is connected with gland, the other end of first connecting rod is connected with a rotating shaft, be wrenched spring and channel bar between second connecting rod and starting bar, first block and second block lay respectively at the both sides of second connecting rod.
Preferably, described first block, first connecting rod, second connecting rod, be wrenched spring, starting bar, channel bar, second block and be arranged in a pressure release cavity.
Positive progressive effect of the present utility model is: the jerking movement mechanism explosion-released valve that the utlity model has auto-lock function can realize need not artificial the replacing and maintenance, and is reusable, and easy to use, the safety coefficient height.
Description of drawings
Fig. 1 is the utility model one embodiment's a structural representation.
Embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, the jerking movement mechanism explosion-released valve that the utlity model has auto-lock function comprises flange 1, first block 2, first connecting rod 3, seal ring 4, gland 5, second connecting rod 6, be wrenched spring 7, rotating shaft 8, starting bar 9, channel bar 10, second block 11, jerking movement spring 12, striking plate 13, the 3rd block 14, valve body 15 and pressure release cavity 16, first connecting rod 3 and second connecting rod 6 constitute the double-toggle connecting rod, flange 1, gland 5 forms a Seal cage with valve body 15, gland 5 is to be connected with valve body 15 by seal ring 4, striking plate 13 is positioned on the inboard of valve body 15, striking plate 13 is connected with an end of jerking movement spring 12, the other end of jerking movement spring 12 is connected with the 3rd block 14, one end of first connecting rod 3 is connected with gland 5, the other end of first connecting rod 3 is connected with rotating shaft 8, be wrenched spring 7 and channel bar 10 between second connecting rod 6 and starting bar 9, first block 2 and second block 11 lay respectively at the both sides of second connecting rod 6, first block 2, first connecting rod 3, second connecting rod 6, be wrenched spring 7, rotating shaft 8, starting bar 9, channel bar 10, second block 11 is arranged in pressure release cavity 16.
When over-pressure gas enters jerking movement mechanism explosion-released valve, at first impact striking plate 13, striking plate 13 upsets make striking plate 13 impact starting bar 9, and starting bar 9 is along rotating shaft 8 upsets, and compress channel bar 10 and be wrenched spring 7, thereby open first connecting rod 3, make first connecting rod 3 break away from second blocks 11 and form toggles, and first connecting rod 3 is blocked by first block 2 and unlocks to 2 motions of first block, this moment, gland 5 was released because of the tension active force of first connecting rod 3, thereby was opened and pressure release by over-pressure gas.In pressure release, striking plate 13 resets rapidly under the effect of jerking movement spring 12 and is blocked by the 3rd block 14, after over-pressure gas is released, gland 5 falls after rise under action of gravity, at channel bar 10 be wrenched and cross toggle position under the effect of spring 7 and blocked by second block 11 and form locking, under the spring force effect of being wrenched spring 7, strain first connecting rod 3 simultaneously, make the spring 7 of being wrenched between first connecting rod 3 and the starting bar 9 cross toggle position, thereby form gland 5 from compressing sealing and locking, can't open gland 5 from outside external force this moment.
The jerking movement mechanism explosion-released valve that the utlity model has auto-lock function comprises jerking movement mechanism and double-toggle connecting rod, and the high mechanical gain when relying on the double-toggle connecting rod to form, the mechanical jerking movement that jerking movement mechanism is produced are finished and packed up fast and release fast.Its basic principle is that the power that acts on member surpasses certain limit, and this power accumulates to a threshold state and causes unexpected motion and cause producing mechanical jerking movement, when causing the double-toggle connecting rod and arriving toggle at the volley, makes high mechanical gain approach infinity.And the destruction toggle then only needs a very little opening force.
Though more than described embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these mode of executions.Therefore, protection domain of the present utility model is limited by appended claims.
