Abstract
The utility model discloses a safety pressure-releasing explosion-proof valve for a capacitor. The safety pressure-releasing explosion-proof valve comprises an explosion-proof plug, a first sealing member and an explosion-proof sleeve. The explosion-proof plug is in threaded nesting cooperation with the explosion-proof sleeve, and the first sealing member is arranged between the explosion-proof plug and the explosion-proof sleeve. The safety pressure-releasing explosion-proof valve also comprises a spring and a hold-down block, a through hole is arranged in the axle center of the explosion-proof plug, a spacing structure is arranged at the upper portion inside the through hole, a contraction port is arranged at the lower portion inside the through hole, the hold-down block is arranged between the spacing structure and the contraction port, and the spring is arranged between the spacing structure and the hold-down block. By employing the safety pressure-releasing explosion-proof valve for the capacitor, the pressure can be released in advance before the internal pressure of the capacitor is increased, so that an accident is prevented, and safety is improved.
Description
Technical field
The utility model relates to a kind of capacitor safety relief explosion-proof valve, belongs to capacitor technology field.
Background technology
The capacitor pore nut generally using in the market, as the access way of inner inserts, only has simple sealing function.As shown in Figure 1, existing capacitor is comprised of nut plug 9, nut sleeve 10, seal 11 with pore nut its structure.Between nut plug 9 and nut sleeve 10 by threaded engagement.When reality is used, after the inside of capacitor inserts has been filled by pore nut, will be furnished with in the nut plug 9 precession nut sleeve 10 of seal 11, and tighten.Once after this pore nut is tightened, just just form an integral body with capacitor casing.If increasing appears in capacitor internal pressure, only have its internal pressure by the time to acquire a certain degree, destroy the weak spot in whole housing, just can carry out earth pressure release.Once this situation occurs, be just easy to occur surprisingly, there is potential safety hazard.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art part, and a kind of capacitor safety relief explosion-proof valve is provided, and uses this explosion-proof valve when capacitor internal pressure increases, to shift to an earlier date release pressure, avoids unexpected generation, improves safety guarantee.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A kind of capacitor safety relief explosion-proof valve, comprise: explosion-proof plug, seal one, anti-explosion set, described explosion-proof plug and described nested cooperation of anti-explosion set screw thread, described seal one is between described explosion-proof plug and described anti-explosion set, also comprise spring and lower compact heap, place, described explosion-proof plug axle center is provided with through hole, in described through hole, top is provided with position limiting structure, in described through hole, below is provided with contraction mouth, described lower compact heap is arranged between described position limiting structure and described contraction mouth, and described spring is between described position limiting structure and described lower compact heap.Described anti-explosion set is for being welded on the seal casinghousing of capacitor.
As the improvement of technique scheme, described position limiting structure comprises limited impression and the circlip that is arranged at described through-hole wall, and described circlip is positioned at described limited impression, and described spring is between described circlip and described lower compact heap.Described structure is convenient to processing and the assembling of safety relief explosion-proof valve for capacitor.
As the improvement of technique scheme, also comprise compact heap, described upper compact heap is between described spring and described circlip.Described upper compact heap has further improved the cooperation intensity of described explosion-proof plug intraware, has improved the reliability of capacitor with safety relief explosion-proof valve.
As the improvement of technique scheme, between described lower compact heap and the outward flange of described contraction mouth, be provided with seal two.Sealing property while further having strengthened capacitor internal normal pressure, prevents that ambient atmosphere from entering capacitor internal.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
Capacitor described in the utility model safety relief explosion-proof valve, when the pressure of capacitor internal reaches or is greater than the maximum working pressure of regulation, the assembly that internal pressure will promote to be embedded in described explosion-proof plug inside upwards, the sealing of described so lower compact heap and described explosion-proof plug bottom will destroy, pressure just discharges from the fit clearance of explosion-proof plug and intraware, reduces the internal pressure of capacitor, removes a hidden danger, thereby avoid unexpected generation, improve safety guarantee.

Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As Figure 2-3, be safety relief anti-explosion valve structure schematic diagram for capacitor described in the utility model.Capacitor described in the utility model safety relief explosion-proof valve, comprising: explosion-proof plug 6, seal 1, anti-explosion set 8, and described explosion-proof plug 6 and nested cooperation of described anti-explosion set 8 screw threads, described seal 1 is between described explosion-proof plug 6 and described anti-explosion set 8; Also comprise spring 3 and lower compact heap 4, described explosion-proof plug 6 places, axle center are provided with through hole 61, the interior top of described through hole 61 is provided with position limiting structure, the interior below of described through hole 61 is provided with contraction mouth 62, described lower compact heap 4 is arranged between described position limiting structure and described contraction mouth 62, and described spring 3 is between described position limiting structure and described lower compact heap 4.Described position limiting structure comprises limited impression 64 and the circlip 1 that is arranged at described through hole 61 inwalls, and described circlip 1 is positioned at described limited impression 64, and described spring 3 is between described circlip 1 and described lower compact heap 4; Described structure is convenient to processing and the assembling of safety relief explosion-proof valve for capacitor.
Further, also comprise compact heap 2, described upper compact heap 2 is between described spring 3 and described circlip 1; Further improve the cooperation intensity of described explosion-proof plug intraware, improved the reliability of capacitor with safety relief explosion-proof valve.Between described lower compact heap 4 and the outward flange 63 of described contraction mouth 62, be provided with seal 25; Sealing property while further having strengthened capacitor internal normal pressure, prevents that ambient atmosphere from entering capacitor internal.
During use, first anti-explosion set 8 is welded on the seal casinghousing of capacitor, because being that screw thread is nested between anti-explosion set 8 and explosion-proof plug 6, coordinates, as long as by the explosion-proof plug assembling 6 assembly precession anti-explosion sets 8.When the pressure of capacitor internal is during lower than the pressure of regulation, explosion-proof valve is under the effect of seal 25 and seal 1, in normal sealing state.When if the pressure of capacitor internal reaches or is greater than the maximum working pressure of regulation, the assembly that internal pressure will promote to be embedded in explosion-proof plug 6 inside upwards, descend like this compact heap 4 and the sealing of explosion-proof plug 6 bottoms to destroy, pressure just discharges from explosion-proof plug 6 and the fit clearance of intraware, reduce the internal pressure of capacitor, remove a hidden danger.
Above content is the detailed description of in conjunction with specific embodiments the utility model being done, and can not assert that the concrete enforcement of the utility model only limits to these explanations.For the utility model person of ordinary skill in the field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to the scope of the utility model protection.
