Abstract
The utility model relates to a sealing module for connecting a condenser tube plate with a water room, and solves the problems of difficult sealing of the tube plate and a water room flange, complex processing and welding technique of the tube plate and water room method, higher mounting cost and weak sealing effect in the prior art. The sealing module comprises a supporting frame and a sealing washer, wherein the supporting frame is inlaid on the sealing washer, and is arranged in the joint of the tube plate and the water room flange. The sealing module is applied in the connection of the condenser water room.
Description
Technical field
The utility model relates to the black box that a kind of vapour condenser tube sheet is connected with hydroecium.
Background technique
Vapour condenser is the important heat transmission equipment in electric power station system Rankine cycle, and cold side medium is 0.3～0.5MPa recirculated cooling water, and as the water of river, lake and sea of closed cycle water, open type, shell-side is higher steam and the water of condensation of quality that approaches vacuum pressure.In order to overhaul conveniently, the flange that is connected to of condenser water box and tube sheet is connected.Vapour condenser profile is huge, and the cold side quantity of circulating water needing is also larger.1000000 nuclear power generating sets condenser tube board sizes even reach 3850 * 6650 * 46, and hydroecium flange thickness reaches 75.So connection of thick large flange and tube sheet, very high to the flatness requirement of tube sheet, hydroecium flange, from technique manufacture angle, reach seal request more difficult, the processing of tube sheet and hydroecium flange, assembly welding technique complexity, installation cost is higher, and sealing effect is bad.
Model utility content
The utility model is in order to solve tube sheet in prior art, hydroecium flange seal difficulty, tube sheet and the processing of hydroecium flange, assembly welding technique complexity, installation cost is higher, and the bad problem of sealing effect, and then the black box that provides a kind of vapour condenser tube sheet to be connected with hydroecium.
The utility model is to address the above problem the technological scheme adopting to be: described black box comprises supporting frame and gasket seal, and gasket seal is embedded on supporting frame, and supporting frame is arranged on the jointing of tube sheet and hydroecium flange.
The beneficial effects of the utility model are: adopt black box of the present utility model, guaranteed the sealing of tube sheet 3 and hydroecium flange 4, sealing effect has strengthened 40%-60%, simultaneously less demanding to the flatness of the surface of contact of tube sheet 3 and hydroecium flange 4, save the operating time, quick and easy for installation, reduce and the corrosion of prevention to link, the present invention also has feature simple in structure, easy to use.
Accompanying drawing explanation
Fig. 1 is that the utility model is used schematic diagram, and Fig. 2 is that gasket seal 2 is embedded in the structural front view on supporting frame 1, and Fig. 3 is the cross-sectional view of Stamping Steel Ribbon 2-1.
Embodiment
Embodiment one: the black box that a kind of vapour condenser tube sheet of present embodiment is connected with hydroecium is described in conjunction with Fig. 1-Fig. 3, described black box comprises supporting frame 1 and gasket seal 2, gasket seal 2 is embedded on supporting frame 1, and supporting frame 1 is arranged on the jointing of tube sheet 3 and hydroecium flange 4.
Embodiment two: the black box that a kind of vapour condenser tube sheet of present embodiment is connected with hydroecium is described in conjunction with Fig. 1-Fig. 2, described gasket seal 2 is to be connected and composed in turn by the different Stamping Steel Ribbon 2-1 head and the tail of a plurality of length, the cross section of Stamping Steel Ribbon 2-1 is trapezoidal, on trapezoidal upper base, be processed with rectangular slot 2-2, on trapezoidal bottom, be processed with " V " type mouth 2-3, other is identical with embodiment one.
Embodiment three: the black box that a kind of vapour condenser tube sheet of present embodiment is connected with hydroecium is described in conjunction with Fig. 1 and Fig. 2, the groove width of described rectangular slot 2-2 is d, and the numerical value of d is 3mm, and the groove depth of rectangular slot 2-2 is h, the numerical value of h is 3.5mm, and other is identical with embodiment two.
Embodiment four: the black box that a kind of vapour condenser tube sheet of present embodiment is connected with hydroecium is described in conjunction with Fig. 1-Fig. 3, described Stamping Steel Ribbon 2-1 is the Stamping Steel Ribbon 2-1 that any one rubber material is made in ethylene propylene diene rubber, neoprene, nitrile butadiene rubber or fluorine rubber, and other is identical with embodiment three.
Embodiment five: in conjunction with Fig. 1-Fig. 3, the black box that a kind of vapour condenser tube sheet of present embodiment is connected with hydroecium is described, support frame as described above 1 is rectangular framework, and other is identical with embodiment one.
Working principle
Supporting frame 1 and gasket seal 2 are arranged between tube sheet 3 and hydroecium flange 4, and be fixedly connected with by link, when work, the water of condenser water box flows to " V " type mouth 2-3, increase the pressure at " V " type mouth 2-3 place, two sidewall outward pressures of " V " type mouth 2-3 are increased, and then increase the sealing of tube sheet 3 and hydroecium flange 4, solved the problem of tube sheet 3 and hydroecium flange 4 poor sealing.
