Abstract
An upper and lower end double sensible pressure sealing ring is a sealing ring for fitter equipment which comprises a sealing ring body as a section special-shaped ring, a sealing ring tablet stretching from upper part of the sealing ring, a groove with downward opening in lower end of the sealing ring, a ring-shaped notch inside the sealing ring, a ring-shaped groove formed between sealing ring body and sealing ring tablet. Advantages of the utility model include: under pressure from different directions, excellent pressure sensitivity and sealing effect is achieved, when negative pressure is formed inside, end face can be sealed well, furthermore it possesses large pressure sensible square and good elastic properties, uneasy for retro gradation, long service life. The device can also be applied together with filter and filtering bag produced by domestic and oversea factories.
Description
Technical field
The two pressure-sensitive seal rings in the utility model upper and lower end face relate to a kind of seal ring, the seal ring that especially a kind of filter plant is used.
Background technique
All will use filter plant in a lot of fields, seal ring then is a requisite constituent element in the filter plant.It is circular that seal ring is generally, and now the most general on the market is the O RunddichtringO, and normal and annular groove is used in combination, although it is light that the O RunddichtringO has, compact advantage, but because its simple structure, especially the state lower seal effect in filter apparatus formation negative pressure is general.
General r shape or J-shaped seal ring can only carry out pressure-sensitive to downforce usually in seal process, to the often effectively pressure-sensitive of power of side direction, thereby make sealing effect descend.
On the other side, and the side direction pressure-sensitive of common Z-shaped seal ring is respond well, but insensitive to the downforce pressure-sensitive, thus cause sealing effect also not satisfactory.
Also have v-ring in addition, this seal ring can produce under the situation of negative pressure at device interior, and is poor by external and internal pressure, makes two sides of seal ring closely be attached on the seal face good sealing effect.It is good especially that but v-ring can not provide usually, and the sealing between the seal ring lateral branch support body, and because stress is concentrated, aging even destroyed easily.
Seal ring is stressed often not to be on the single direction, downforce to be arranged, and pressure laterally also has laterally the tiltedly pressure of below.In order to reach good sealing effect, will make the power of all these all directions that are subjected to all change into the power that seal ring and the supporting frame that is enclosed within the outside can be fitted tightly as much as possible, and this be existing numerous seal rings can't finish.
Summary of the invention
The two pressure-sensitive seal ring technical problems to be solved in the utility model upper and lower end face are to provide a kind of when being subjected to the pressure of a plurality of directions, and each position is the seal ring of the good pressure-sensitive of energy all.
For solving the problems of the technologies described above, the utility model provides a kind of upper and lower end face two pressure-sensitive seal rings, comprises seal ring body, wherein, described seal ring is cross section special-shaped ring, the seal ring piece of the upper-end surface of seal ring for stretching out to the inside, and the lower end surface seal ring body is provided with the groove that Open Side Down;
For pressure and the increase lifting surface area of concentrating outside skew back below, sealing ring body inboard is provided with an annular notch, forms an annular groove between seal ring piece and the seal ring body.
For making when being subjected to downforce pressure-sensitive more responsive, the described radial cross section of going up diaphragm seal is shaped as thread form or bar shaped.
In order to reach better sealing effect with the lateral branch support, the exterior edge face of the two pressure-sensitive seal rings in upper and lower end face is the ring surface that fits tightly with outer support.
In order to make seal ring when being subjected to a plurality of direction upward pressure, all can good pressure-sensitive, thus reaching better sealing effect, upper sealing ring sheet and seal ring body fuse in the outside.
Described annular groove be laterally tiltedly down to annular groove.
For making seal ring have the better elastic performance, described seal ring is made of plastics.
The utility model has the advantages that:
1, when being subjected to a plurality of direction upward pressure, all can good pressure-sensitive, sealing effect is good;
2, when inside forms negative pressure, also can be well with end face seal;
3, the pressure-sensitive area is big;
4, elastic performance is good, is difficult for wearing out long service life;
5, with both at home and abroad filter, the filter bag of manufacturer production all can supportingly use.

Embodiment
See also shown in the phantom of the two pressure-sensitive seal rings in accompanying drawing the utility model upper and lower end face, the two pressure-sensitive seal rings in a kind of upper and lower end face, comprise seal ring body 2, wherein, described seal ring is cross section special-shaped ring, the seal ring piece 1 of the upper-end surface of seal ring for stretching out to the inside, the radial cross section of sealing ring plate 1 is shaped as thread form.
The lower end surface sealing is gone back body 2 and is provided with the groove 21 that Open Side Down, and its inboard is provided with an annular notch 22.
Form an annular groove 3 between seal ring piece 1 and seal ring body 2, this annular groove 3 is offered towards outer skew back below, and opening is slightly wide, and certain depth is arranged, but does not destroy the join strength between seal ring piece 1 and the seal ring body 2.
Seal ring piece 1 fuses in the outside of seal ring with seal ring body 2.
The exterior edge face of the two pressure-sensitive seal rings in the utility model upper and lower end face is the ring surface that fits tightly with supporting frame 5 inboards.
The joint of seal ring bottom is affixed with the filter bag 4 sack hot melts that are sleeved on the outside, in case of necessity also can be fixed in the guard in filter bag 4 outsides affixed with cover, place the inside of supporting frame 5 then in the lump.The two pressure-sensitive seal rings in upper and lower end face place on the ladder platform 51 of supporting frame 5, and two pin that form in seal ring body 2 bottoms are in the same plane.
When seal ring was subjected to a plurality of sides and upwards pressure, as downforce, pressure laterally outwards during the pressure of skew back below, all can fit tightly with supporting frame 5, thereby reach efficient sealed effect.
The two pressure-sensitive seal rings in the utility model upper and lower end face are made of plastics.
