Abstract
The utility model relates to a rubber mat used in a heat exchanger slab. The rubber mat comprises a rubber mat body, wherein the rubber mat body adopts a tenon buckle structure and is matched with a concave-convex groove of the heat exchanger slab; the rubber mat body has an upper main sealing surface and a lower main sealing surface; and a first main sealing surface of the rubber mat body is boss-shaped, and a second main sealing surface is flat or is concave. Compared with the prior art, the rubber mat has challenges of high pressure, high temperatures, expansion and retraction of materials and the like in certain applications, and can execute the hydraulic or atmospheric pressure sealing function well and improve the reliability of the heat exchanger slab greatly at the same time.
Description
Technical field
The utility model relates to the heat exchanger field, is specifically related to the rubber cushion for heat exchanger plate.
Background technology
plate type heat exchanger is comprised of one group of corrugated metal plate, the hole, angle is arranged on plate, pass through for the two media that conducts heat, metal sheet is arranged in a framework that fixed pressure plate and movable pressure plate arranged, and clamp with bolt, rubber sheet gasketing is housed between plate, the fluid passage is sealed, and guide cold, hot fluid alternately flow in separately passage, the flow of fluid, physical property, Pressure Drop and temperature difference have determined specification and the quantity of plate, corrugated plating has not only aggravated turbulent extent, and form many strong points, be enough to bear the pressure differential between medium, form corrugated passage between each plate, carry out heat exchange by plate, liquid-liquid, liquid-vapour carries out the ideal equipment of heat exchange.
The further design main points of many heat exchangers relate to the use of the pad in heat exchanger plate, and such pad must be subject in some applications high pressure, high temperature, material and expands and shrink and carry out its hydraulic pressure or pressurized seal function when other challenge.Pad is extremely important in various application reliably, and existing rubber cushion reliability is not high, easily produces between pad and plate and slides.
The utility model content
The utility model purpose: the purpose of this utility model is the problem that exists in order to solve above-mentioned rubber cushion for heat exchanger plate, provides a kind of sealing property the better rubber cushion that is used for more reliably heat exchanger plate.
Technical scheme: the utility model for achieving the above object, the technical scheme of employing is:
A kind of rubber cushion for heat exchanger plate, comprise the rubber cushion body, described rubber cushion body is the tenon buckle structure, and the tongue and groove of rubber cushion body and heat exchanger plate is complementary, described rubber cushion body has two primary sealing areas in up and down, and the first primary sealing area of described rubber cushion body is boss-shaped.
The second primary sealing area of described rubber cushion body is plane or concavity.
Beneficial effect: compared with prior art, rubber cushion described in the utility model is subject in some applications high pressure, high temperature, material and expands and shrink and when other challenge, can well carry out its hydraulic pressure or pressurized seal function, greatly improve the unfailing performance of heat exchanger plate.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1 rubber cushion.
The specific embodiment
As shown in Figure 1, a kind of rubber cushion for heat exchanger plate, comprise rubber cushion body 1, rubber cushion body 1 is the tenon buckle structure, and rubber cushion body 1 is complementary with the tongue and groove of heat exchanger plate, and rubber cushion body 1 has two primary sealing areas in up and down, the first primary sealing area of rubber cushion body 1 is boss-shaped, the second primary sealing area is plane or concavity, and what the plate of large specification adopted is concavity, and what the plate of small dimension adopted is the plane.Rubber cushion described in the utility model is subject in some applications high pressure, high temperature, material and expands and shrink and when other challenge, can well carry out its hydraulic pressure or pressurized seal function, has greatly improved the unfailing performance of heat exchanger plate.
Claims (2)
