Description
Technical field
The utility model relates to a kind of sentinel valve, particularly a kind of type submerged electromagnetic pulse valve.
Background technique
Type submerged electromagnetic pulse valve is a kind of of sentinel valve, be mainly used in sack cleaner, it utilizes the variation of gas pressure that the pressurized gas in gas bag is jetted in the air chamber of sack cleaner, and the solid dust that makes to be attached on filtering material breaks away from, be the crucial accessory of sack cleaner, be widely used in treating flour dust and the assembling sphere of every profession and trade.
Because type submerged electromagnetic pulse valve is to be connected with gas bag, simultaneously in gas bag, be full of pressurized air, valve seal is mainly to utilize bolt force that O-ring seals is deformed to produce seal pressure to guarantee.And the sealing effect of O-ring seals depends on the coupling of O-ring seals size and groove to a great extent, in prior art, often be designed to the cross section diameter of seal ring, no matter perhaps the seal ring cross section diameter is much, seal ring is than ditch groove width 0.5mm, its defect is easily to damage seal ring and groove, reduces withstand voltage poor ability, and inconvenient maintenance.And the winding-up bobbin seal circle of valve body is due to position relationship, after wear out failure, its dismounting and change is inconvenience comparatively.Simultaneously, in submerging pulse valve, there is defect in spring aspect fatigue life and relaxation resistance, easily causes diaphragm fluctuation of service under gas pressure.
Summary of the invention
The deficiency that the utility model exists for prior art, provide a kind of simple in structure, easy to maintenance, stable type submerged electromagnetic pulse valve.
The utility model is achieved through the following technical solutions: a kind of type submerged electromagnetic pulse valve, comprise electromagnetic priority valve, one-level valve gap, one-level spring, first diaphragm assembly, secondary valve gap, two-level spring, secondary diaphragm unit, valve base, described electromagnetic priority valve is arranged on one-step valve and covers, the one-level valve gap is arranged on secondary valve and covers, and is provided with one-level spring and first diaphragm assembly between one-level valve gap and secondary valve gap; The secondary valve gap is arranged on valve base, is provided with two-level spring and secondary diaphragm unit between secondary valve gap and valve base; Described one-level, two-level spring adopt conical helical spring; On valve base, set base seal circle is arranged in base seal circle groove; In set winding-up sleeve pipe, the bobbin seal circle is set on valve base, described bobbin seal circle is arranged in bobbin seal circle groove, and described base seal circle groove groove width is 1～1.5 times of seal ring cross section diameter, the groove inboard semicircle boss that is uniformly distributed along the circumference; Bobbin seal circle groove is provided with the quick detach notch.
Further technological scheme is: the quantity of described semicircle boss is 8～12; Described one-level spring small end is located at one-step valve and covers, and large end is located on the first diaphragm assembly; Described two-level spring small end is located at secondary valve and covers, and large end is located on the secondary diaphragm unit.
The beneficial effects of the utility model are: because valve base o-ring groove groove width is 1～1.5 times of seal ring cross section diameter, and be provided with the semicircle boss of circumference uniform distribution, make O-ring seals easy to loading and unloading, and be contained in preferably in groove after compression, thereby form rational seal ring decrement and amount of tension, the inefficacy that reduces seal ring damages, and improves sealability; By on bobbin seal circle groove, the quick detach notch being set, be very easy to the dismounting and change of this place's seal ring, simultaneously one-level, two-level spring are used conical helical spring, and make one-level spring small end be located at one-step valve to cover, and large end is located on the first diaphragm assembly; The two-level spring small end is located at secondary valve and covers, and large end is located on the secondary diaphragm unit, is conducive to eliminate resonance, promotes first diaphragm and secondary diaphragm operation stability.
Therefore, the utlity model has simple in structure, easy to maintenance, stable advantage.
