Abstract
The utility model discloses a novel intermediate connecting tube box of indirect cooling tube bundles. The intermediate connecting tube box comprises bolts, an upper connecting tube box body, a lower connecting tube box body and base tubes, the base tubes are connected in the upper connecting tube box body and the lower connecting tube box body, sealing gaskets are arranged at the joint of the upper connecting tube box body and the lower connecting tube box body, the upper connecting tube box body and the lower connecting tube box body are connected through the bolts, adhesives are arranged at the joints of the upper connecting tube box body and the base tubes and the joints of the lower connecting tube box body and the base tubes, and the joints of the upper connecting tube box body and the base tubes and the joints of the lower connecting tube box body and the base tubes are free of being welded by metal. The intermediate connecting tube box is simple in structure, long in service life and easy to maintain.
Description
Technical field
The utility model relates to steam turbine field, specifically a kind of the novel intermediate connection tube case of cooler tube bundle.
Background technology
The indirect air cooling tube bank is mainly used in the exhaust steam of cooling steam turbine afterbody discharging.Generally be arranged in double-curve cooling column bottom surrounding or the inside of tower, utilize water vapour in the principle cooling tube bundle of gravity-flow ventilation in tower, and condense into water it is recycled.Connected mode between tradition between cooler tube bundle is that tube sheet connects, and adopts expanded joint between parent tube and tube sheet, and uses seal with elastometic washer.This connected mode exists rubber ring easily aging, causes recirculated cooling water to be revealed, and needs periodic replacement, and maintenance cost is high.Simultaneously, all corresponding series connection one by one of every foundation pipe between a cooler tube bundle, in case revealing appears in certain foundation pipe of one of them tube bank, all parent tubes of series connection are all blocked together from top to bottom, can not play through-flow and the heat exchange effect.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, long service life, the novel intermediate connection tube case of cooler tube bundle between being easy to safeguard.
The utility model is achieved through the following technical solutions:
The novel intermediate connection tube case of a kind of cooler tube bundle of the present utility model, comprise bolt, upper tube connector casing and lower tube connector casing, and be arranged on parent tube in tube connector casing and lower tube connector casing, described upper tube connector casing and lower tube connector casing junction are provided with sealing gasket, and described upper tube connector casing is connected by bolt with lower tube connector casing.
Technical scheme further, described upper tube connector casing and lower tube connector casing and parent tube junction are equipped with bonding agent, and described upper tube connector casing and lower tube connector casing and parent tube junction are all without metal solder.
Technical scheme further, described parent tube is pipe or elliptical tube.
The beneficial effects of the utility model are: between this enforcement, the novel intermediate connection tube case of cooler tube bundle adopts the compoiste adhering material, and parent tube and bobbin carriage are bonded together.Compound binding agent intensity is greater than weld strength, and the life-span can reach 30 years.Simultaneously, bobbin carriage also plays the effect of mixed warm device, eliminates and respectively arranges recirculated cooling water temperature contrast in parent tube, effectively reduces parent tube bursting by freezing in winter risk.If certain foundation pipe breaks down, the normal use of other parent tubes will can not had influence on after its shutoff.Between the present invention significantly reduces, the maintenance cost of cooler tube bundle more than 30%, has improved the safety coefficient of equipment.It is simple in structure, and long service life is easy to safeguard.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the novel intermediate connection tube box structure of a kind of cooler tube bundle of the present utility model schematic diagram;
Fig. 2 is the generalized section of B-B;
Fig. 3 is the P partial schematic diagram.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the novel intermediate connection tube case of a kind of cooler tube bundle of the present utility model, comprise bolt 4, upper tube connector casing 1 and lower tube connector casing 5, and be arranged on parent tube 2 in tube connector casing 1 and lower tube connector casing 5, described upper tube connector casing 1 and lower tube connector casing 5 junctions are provided with sealing gasket 3, and described upper tube connector casing 1 is connected by bolt 4 with lower tube connector casing 5.
Wherein, described upper tube connector casing 1 and lower tube connector casing 5 is equipped with bonding agent 6 with parent tube 2 junctions, described upper tube connector casing 1 and lower tube connector casing 5 with parent tube 2 junctions all without metal solder.
Described parent tube 2 is pipe or elliptical tube.
The beneficial effects of the utility model are: between this enforcement, the novel intermediate connection tube case of cooler tube bundle adopts the compoiste adhering material, and parent tube and bobbin carriage are bonded together.Compound binding agent intensity is greater than weld strength, and the life-span can reach 30 years.Simultaneously, bobbin carriage also plays the effect of mixed warm device, eliminates and respectively arranges recirculated cooling water temperature contrast in parent tube, effectively reduces parent tube bursting by freezing in winter risk.If certain foundation pipe breaks down, the normal use of other parent tubes will can not had influence on after its shutoff.Between the present invention significantly reduces, the maintenance cost of cooler tube bundle more than 30%, has improved the safety coefficient of equipment.It is simple in structure, and long service life is easy to safeguard.
The above be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work is within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
Claims (3)
