Description

Rubber gasket for sealing heat exchanger

Technical Field

The utility model belongs to the technical field of plate heat exchanger, concretely relates to sealed heat exchanger cushion.

Background

The plate heat exchanger is formed by a plurality of corrugated thin plates which are sealed at certain intervals by gaskets, and are overlapped and locked by frames and compression screws, the plate and the gasket are provided with four corner holes, the four corner holes form a fluid distribution pipe and a fluid collection pipe, and simultaneously, cold and hot fluids are reasonably separated and respectively flow in flow channels at two sides of each plate to carry out heat exchange through the plate. The sealed cushion is made by rubber materials and is located between two slabs, and the heat exchanger sealed cushion receives the impact at work, thereby joint strip receives outside power and probably arouses the displacement to lead to the sealing force not enough, and because the adhesive tape junction is in the same place for later stage postvulcanization cross-linking, the junction area is little, probably splits under the circumstances of many times atress work, will influence the heat transfer effect in the use.

Disclosure of Invention

For solving the above-mentioned not enough problem of sealing because displacement and adhesive tape vulcanize and the fracture leads to easily that the cross-linking area is little, the utility model discloses a sealed heat exchanger cushion, simple structure, loading and unloading are convenient, can prevent the whole displacement of cushion, reach the sealed effect of long-term work.

In order to achieve the purpose, the technical scheme of the invention is as follows:

the utility model provides a sealed heat exchanger cushion, contains the cushion body, the cushion body inlays on heat transfer plate recess, the cushion body comprises angle hole parcel adhesive tape and linear adhesive tape, be connected with many brace rods between angle hole parcel adhesive tape and the linear adhesive tape, linear adhesive tape with angle hole parcel adhesive tape equidistance outwards is equipped with the spacing lug of a plurality of rubbers, the recess of inlaying of heat transfer plate is equipped with the depressed part that corresponds with it.

Furthermore, the joint of the supporting rib and the corner hole wrapping rubber strip and the linear rubber strip is provided with a rubber limiting bump towards the direction of the heat exchange plate, and a concave part corresponding to the heat exchange plate is arranged in the embedding groove of the heat exchange plate.

Furthermore, a plurality of T-shaped clamping rubber strips are arranged on the outer side of the rubber mat body, and the heat exchange plate sheets are provided with corresponding embedding grooves.

Furthermore, the number of the rubber limiting convex blocks is equal to that of the concave parts.

Furthermore, the number of the T-shaped clamping rubber strips is equal to that of the embedding grooves.

The utility model has the advantages that:

the limiting lug is arranged outwards on the outer side of the rubber mat body, so that the rubber mat is prevented from deviating from the groove due to the outward expansion bulge caused by the pressing of the rubber mat, and when the rubber mat is influenced by the pressing, the limiting lug limits the rubber mat in the groove, and displacement cannot be generated; the limiting bump is arranged at the joint of the supporting rib, the corner hole wrapping rubber strip and the linear rubber strip, so that the area of the joint is increased, the pressed easy-cracking path is lengthened, the pressure bearing capacity and the anti-cracking capacity are also enhanced, and the sealing performance is improved.

Detailed Description

The present invention will be further elucidated below with reference to the accompanying fig. 1-3 and the embodiments, it being understood that the embodiments described below are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

It should be noted that the terms "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1, a rubber gasket for a sealed heat exchanger comprises a rubber gasket body 1, grooves corresponding to the heat exchange plates 7 are formed in the heat exchange plates 7, and the rubber gasket body 1 is embedded in the grooves of the heat exchange plates 7. The rubber mat body 1 is composed of an angle hole wrapping rubber strip 3 and a linear rubber strip 2, the angle hole wrapping rubber strip 3 and the linear rubber strip 3 seal the outer peripheries of two heat exchange plates 7 to form a space for flowing of fluid needing heat exchange.

As shown in fig. 1 and 2, the corner hole wrapping rubber strip 3 and the linear rubber strip 2 are connected with a plurality of supporting ribs 5 at the corner hole connection part, the rubber material of the supporting ribs 5 has a certain supporting property, the supporting ribs 5 and the connection part of the corner hole wrapping rubber strip 3 and the linear rubber strip 2 are provided with rubber limiting lugs 6 in the heat exchange plate 7, the limiting lugs at the connection part increase the contact area of the connection part, so that the easy-cracking path under pressure is lengthened, the pressure bearing capacity and the anti-cracking capacity are both increased, and meanwhile, the sealing effect is not influenced by limiting, fixing and shifting easily.

Linear adhesive tape 2 with 3 equidistance outwards of angle hole parcel adhesive tape is equipped with a plurality of rubber limit protruding blocks 6, the recess of inlaying of heat transfer sheet 7 be equipped with the depressed part that limit protruding block 6 corresponds, at the heat exchanger during operation, the cushion body pressurized receives outside effort, sets up limit protruding block 6 and the depressed part of inlaying that corresponds in the cushion body 1 outside, when the pressurized receives outside effort, the restriction does not take place the displacement in original position, improves sealing performance.

The outer side of the rubber mat body 1 is provided with a plurality of T-shaped clamping rubber strips 4, the heat exchange plate pieces 7 are provided with corresponding embedding grooves, and the T-shaped clamping rubber strips 4 completely fix the rubber mat body 1 on the heat exchange plate pieces 7.

In conclusion, the limiting convex blocks arranged outwards on the outer side of the rubber mat body prevent the rubber mat from deviating from the grooves due to outward expansion of the rubber mat under pressure, and the limiting convex blocks limit the rubber mat in the grooves without displacement when the rubber mat is influenced by pressure; the limiting bump is arranged at the joint of the supporting rib, the corner hole wrapping rubber strip and the linear rubber strip, so that the area of the joint is increased, the pressed easy-cracking path is lengthened, the pressure bearing capacity and the anti-cracking capacity are also enhanced, and the sealing performance is improved.

It should be noted that the appended drawings illustrate only the technical idea of the invention and are not intended to limit the scope of the invention in such shapes, and that those skilled in the art can make various modifications and decorations without departing from the principle of the invention, which fall within the scope of the appended claims.
