Description

Special rubber ring for cover plate of environmental protection equipment

Technical Field

The utility model relates to an equipment seal field especially relates to a special rubber circle of environmental protection equipment apron.

Background

Along with the continuous reinforcing of people's environmental protection consciousness, environmental protection equipment constantly develops, the society also constantly increases to environmental protection equipment's demand, among this current environmental protection equipment, a dust removal case has, the dust removal case has an air inlet and a gas outlet, there is the filter core dust removal incasement portion, the mist that contains solid particle thing gets into the dust removal case from the air inlet, discharge by the gas outlet after filtering through the filter core, play the effect to gaseous edulcoration, in order can conveniently dismantle, change the filter core, dust removal case side opening, cover the opening with a circular apron, play sealing action, promote sealing performance with the rubber circle between circular apron and the equipment surface, current rubber circle is single-layer construction, the dismouting is inconvenient, easily cause the damage during the dismantlement installation, single-layer rubber circle laminating equipment surface is inseparable enough, sealing performance remains to be promoted.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a special rubber circle of environmental protection equipment apron that sealing performance is better and easy dismounting.

In order to solve the technical problem, the utility model adopts the technical scheme that: the special rubber ring for the cover plate of the environmental protection equipment has the innovation points that: it is inboard to inject one side that environmental protection equipment apron is close to the equipment surface, and the one side of keeping away from the equipment surface is the outside, the special rubber circle of environmental protection equipment apron includes interior rubber ring and outer rubber ring, interior rubber ring is connected with the outer rubber ring outside, outer rubber ring surface is the plane, one side that outer rubber ring was kept away from to interior rubber ring is the arcwall face, and one side that is close to outer rubber ring is the plane, one side that interior rubber ring plane, outer rubber ring are close to interior rubber ring and outer rubber ring junction form one jointly and hold the apron outer annular groove of personally submitting the rectangle along male transversal, interior rubber ring is inside to be hollow.

Furthermore, an annular opening along the circumferential direction of the inner rubber ring is formed in the plane of one side, close to the outer rubber ring, of the inner rubber ring, and the annular opening is communicated with the inner cavity of the inner rubber ring.

The utility model has the advantages that:

1) one side that outer rubber ring was kept away from to interior rubber ring is the arcwall face, and when the apron was screwed up, the arcwall face atress produced deformation, can paste tight equipment surface better, provides better sealing performance, interior rubber ring encircles inside is hollow, can also make when having saved material cost the better laminating equipment surface of arcwall face of one side that outer rubber ring is kept away from to interior rubber ring obtains better sealing performance.

2) The plane of one side of the inner rubber ring close to the outer rubber ring is provided with an annular opening along the circumferential direction of the inner rubber ring, so that the stress at the joint of the inner rubber ring and the outer rubber ring can be shared when the rubber ring is detached, the occurrence of the fracture condition is reduced, and the durability is improved.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is the utility model relates to a main view schematic diagram of the special rubber circle of environmental protection equipment apron.

Fig. 2 is the utility model relates to a cross section schematic diagram of special rubber circle of environmental protection equipment apron.

In the figure: 1. an outer rubber ring; 2. an inner rubber ring; 3. the inner rubber ring is opened; 4. the inner rubber ring is annularly provided with an arc surface.

Detailed Description

The following examples are presented to enable those skilled in the art to more fully understand the present invention and are not intended to limit the scope of the present invention.

1. The special rubber ring for the cover plate of the environmental protection equipment shown in figure 1 is composed of an outer rubber ring 1 and an inner rubber ring 2, one side of the rubber ring close to the cover plate is the inner side, one side of the rubber ring far away from the cover plate is the outer side, the inner rubber ring 2 is connected with the outer side of the outer rubber ring 1, the surface of the outer rubber ring 1 is a plane, one side of the inner rubber ring 2 far away from the outer rubber ring is an arc-shaped surface 4, one side of the inner rubber ring 2 close to the outer rubber ring 1 is a plane, the plane of the inner rubber ring 2, one side of the outer rubber ring 1 close to the inner rubber ring 2 and the joint of the inner rubber ring 2 and the outer rubber ring 1 form an annular groove with a cross section being rectangular, and the groove is used for fixing the rubber ring and the cover plate and increasing the sealing performance.

The arc-shaped surface 4 deforms after being extruded after the cover plate is screwed down, can be tightly attached to the surface of an instrument and provides better sealing performance, and an annular opening 3 along the circumferential direction of the inner rubber ring 2 is formed in the plane of one side, close to the outer rubber ring 1, of the inner rubber ring 2; the inner rubber ring 2 is hollow, the annular opening 3 is communicated with the inner cavity, and the rubber ring with the structure is applied, so that the stress at the joint of the inner rubber ring and the outer rubber ring is reduced when the rubber ring is disassembled and assembled, and the rubber ring is not easy to damage.

The rubber ring special for the cover plate of the environmental protection equipment shown in figure 1 is made of nitrile rubber, and has the advantages of excellent oil resistance, high wear resistance, high heat resistance and strong bonding force.

It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
