Abstract
The utility model relates to a tubular heat exchanger with double sealing rings. The heat exchanger is internally provided with a plurality of parallel tube nests, the two ends of the tube nests are fixedly connected with a tube plate of the heat exchanger, the two ends of the tube nests are provided with end socket covers which are internally provided with grooves, and the grooves are internally provided with the sealing rings for sealing the tube nests. Compared with the prior art, the tubular heat exchanger has the advantages that the double sealing rings can be used in the end socket covers of any heat exchanger, a better sealing effect is achieved, the sealing rings are made of rubber materials and have certain shrinking and tensioning functions, and the sealing rings can be firmly clamped in the clamping grooves of the end socket covers and cannot fall off easily.
Description
Technical field
The utility model relates to a kind of pipe heat exchanger, especially relates to a kind of pipe heat exchanger with Double seal ring.
Background technology
Heat exchanger is simple in structure, lightweight now, and cost is lower, in identical shell situation, can arrange some heat transfer pipes compared with the tubular heat exchanger of other patterns more.But the temperature difference of the fluid between housing and pipe layer can not be too large, because the temperature difference is when too large, can produce larger thermal stress, make tube-to-tube sheet connection junction get loose and produce leakage.In addition this class heat exchanger is fixed because of tube sheet, so in maintenance, when retubing or cleaning shell, all more difficult.It is less scaling that this heat exchanger is applicable to shell side medium, or have fouling but can carry out the occasion of Chemical cleaning; Shell wall and tube wall because of the difference of the swell increment that temperature difference causes little, though or the large not high situation of shell side pressure of differential expansion.
Utility model content
The purpose of this utility model is exactly to provide in order to overcome the defect of above-mentioned prior art existence the pipe heat exchanger with Double seal ring that a kind of scope of application is wide, safe and reliable, airtight performance is good.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of pipe heat exchanger with Double seal ring, some tubulations that be arranged in parallel in heat exchanger, the two ends of tubulation are fixedly connected with the tube sheet of heat exchanger, and the two ends of described tubulation are provided with end socket cover, in this end socket cover, offer groove, in this groove, be provided for sealing the sealing ring of tubulation.
Described groove is provided with twice, is equipped with a sealing ring in each groove, like this by two seals circle is set, even if a sealing ring damages, still can reach the effect of sealing.
Described sealing ring is the sealing ring of quality of rubber materials, and sealing ring can be stuck in the groove in end socket cover firmly. can better seal.
Compared with prior art, the utlity model has following advantage:
One, the scope of application is wide: Double seal ring design can be used in the end socket cover of any heat exchanger, makes it reach better sealing effectiveness;
Two, safe and reliable: this adopts Double seal ring design, for after preventing that one of them sealing ring from damaging, can not reach the effect of sealing, thereby use double containment exactly, ensured its sealing effectiveness;
Three, airtight performance is good: sealing circle adopts quality of rubber materials, has certain contraction and tensioning function, can be stuck in firmly in the middle of the draw-in groove of end socket cover, is difficult for dropping.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is that sealing ring, 2 is that groove, 3 is end socket cover.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
A kind of pipe heat exchanger with Double seal ring, some tubulations be arranged in parallel in heat exchanger, the two ends of tubulation are fixedly connected with the tube sheet of heat exchanger, the two ends of tubulation are provided with end socket cover 3, in this end socket cover 3, offer groove 2, for the utility model, in end socket cover 3, offer twice groove 2, the sealing ring 1 that is provided for sealing tubulation in groove 2, said structure as shown in Figure 1.
The structure of end socket being overlapped to 3 parts is below further described, the groove 2 of offering on end socket cover 3 has twice, is equipped with a sealing ring 1, like this by two seals circle 1 is set in each groove, even if a sealing ring 1 damages, still can reach the effect of sealing.The sealing ring that the sealing ring 1 using is quality of rubber materials, sealing ring 1 can be stuck in the groove 2 in end socket cover firmly, can better seal, especially in the larger occasion of variations in temperature, due to temperature difference, the gap of sealing place can be had a greater change, by the sealing ring 1 of quality of rubber materials is set, the contraction itself possessing and tensioning function are that it can change along with the variation in gap, thereby make heat exchanger have good sealing property.
Claims (3)
1. with a pipe heat exchanger for Double seal ring, some tubulations that be arranged in parallel in heat exchanger, the two ends of tubulation are fixedly connected with the tube sheet of heat exchanger, it is characterized in that,
