Abstract
The utility model discloses a seal structure of a heat exchanger. The seal structure comprises a shell flange and a first seal ring. A second flange and a second seal ring are arranged between the shell flange and an end cap. An inner torus surface of the second flange consists of a large-diameter torus surface on the left and a small-diameter torus surface on the right. A ring protrusion is arranged on the lower portion of the right end face of the second flange, matched with the large-diameter torus on the right side of the shell flange and opposite to the second seal ring arranged in the large-diameter torus. Each bolt penetrates an end cap bolt hole, a second flange bolt hole and a threaded hole of the shell flange. The seal structure has the remarkable advantage of preventing lubricating oil and water from being mixed with each other after the seal ring is broken.
Description
Technical field:
The utility model relates to the hermetically-sealed construction of a kind of hot swapping, particularly a kind of heat exchanger.
Background technology:
Tubular heat exchanger is gone here and there chamber for fear of You Heshui, between the general flange at housing two ends and front and rear cover, O RunddichtringO is set, this hermetically-sealed construction is in use when aging the breaking of O RunddichtringO caused profit string chamber, once there is lubricating oil and cooling water string chamber, in lubricating oil, contained after water, can have a negative impact to engine, now not only change O RunddichtringO, also will be by whole oil changes.
Summary of the invention:
The purpose of this utility model is to provide a kind of hermetically-sealed construction that prevents a kind of heat exchanger in profit string chamber.
The technical scheme that realizes the utility model object is, a kind of hermetically-sealed construction of heat exchanger, comprise shell flange and the first sealing ring, it is characterized in that: between shell flange and end cap, be also provided with the second flange and the second sealing ring, the large diameter circle face that the interior anchor ring of described the second flange is left side and the small-diameter circular anchor ring on right side form, the bottom of the right side of described the second flange arranges the prominent body relative with the second sealing ring being located in this large diameter circle of the annular matching with the large diameter circle on described shell flange right side, bolt is through at above-mentioned bolt of cover via hole, in the screwed hole of the second flange bolt via hole and shell flange.
The utility model has sealing ring compared with the prior art damage after oil and water can not go here and there the remarkable advantage in chamber.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Accompanying drawing is elaborated to the utility model with the following Examples.Tubular heat exchanger is comprised of housing 1, cooling tube 2, dividing plate 3, housing two end flanges 4, the first sealing ring 5, end cap 8.The utility model damages for solving sealing ring the defect that causes profit string chamber, between shell flange and end cap, set up a second annular flange 6, and the second sealing ring 7 is set between end cap and the second flange, with screw 9, be through at above-mentioned bolt of cover via hole, in the second flange bolt via hole and shell flange screwed hole, make it to be tightly connected, the left side of the interior anchor ring of described the second flange for large diameter circle face right side be small-diameter circular anchor ring, the bottom of its right end face of described the second flange is for stretching in interior and relative with the first sealing ring prominent body of annular of large diameter circle in shell flange left side outward, in the large diameter circle face of described the second flange, be provided with the second sealing ring, the prominent body of the overhanging annular of the bottom of end cap inner face is placed in the large diameter circle of the second flange and relative with the second sealing ring.
The utility model is owing to setting up the second flange and the second sealing ring between shell flange and end cap, when there is oil leak, illustrate that the first sealing ring breaks, now lubricating oil can not enter in water cavity, when the second sealing ring breaks, cooling water in water cavity can only can not be gone here and there chamber and enter in oil pocket and engine by external leakage, and it is that sealing ring that this hermetically-sealed construction can accurately be judged impaired, and guarantees can not go here and there chamber accident.
