SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide a condenser return water room, improve the gas tightness greatly.

In order to achieve the above object, the technical solution of the present invention is to provide a condenser water return chamber, which comprises a housing, a partition plate disposed in the housing, a connecting flange fixed to one end of the housing, an interface flange connected to the connecting flange, and two connecting pipes fixedly disposed on the side of the housing and connected to the inner cavity of the housing, wherein a sealing gasket is disposed between the connecting flange and the interface flange and fixedly connected to the connecting flange via a plurality of fasteners, the connecting flange is provided with a plurality of first through holes matched with the fasteners, the interface flange is provided with second through holes matched with the fasteners, the sealing gasket is provided with third through holes matched with the fasteners, the sealing gasket is circular, a side surface of the sealing gasket is provided with a first convex ring concentrically disposed with the sealing gasket and having a circular shape, the opposite side of sealed pad is provided with rather than concentric setting and is the annular second protruding circle of circle, first protruding circle and the second protruding circle is located respectively the both sides of third through hole, flange with set up on the connection terminal surface of interface flange with first protruding circle matched with first recess, the interface flange with set up on the connection terminal surface of flange with second protruding circle matched with second recess.

The further improvement is that: the two connecting pipes and the shell are welded and fixed through the connecting pipe flanges.

The further improvement is that: the outer surface of the shell is symmetrically provided with two lifting lugs.

The further improvement is that: the shell and the connecting flange are fixed in a welding mode.

The utility model has the advantages and the beneficial effects that: through carrying out the innovative design to sealed the pad, increased protruding circle respectively in its both sides, and flange on the casing has also been done the improvement with interface flange's the face of being connected and has been set up with protruding circle matched with recess, when the assembly, the protruding circle of sealed pad both sides is located two recesses respectively, rethread fastener with flange and interface flange locking, if careless certain fastener does not lock and cause sealed pad to take place when small the deformation, because it still can guarantee fine gas tightness effect with the restriction of recess of protruding circle.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-4, a condenser backwater chamber comprises a housing 1, a partition plate 2 disposed in the housing 1, a connecting flange 3 fixed to one end of the housing 1, an interface flange 4 connected to the connecting flange 3, and two connecting pipes 10 fixedly disposed on a side surface of the housing 1 and communicated with an inner cavity of the housing 1, wherein a sealing gasket 5 is disposed between the connecting flange 3 and the interface flange 4 and fixedly connected to the connecting flange through a plurality of fasteners, a plurality of first through holes matched with the fasteners are disposed on the connecting flange 3, a second through hole matched with the fasteners is disposed on the interface flange 4, a third through hole matched with the fasteners is disposed on the sealing gasket 5, the sealing gasket 5 is annular, a first convex ring 6 concentrically disposed with the sealing gasket 5 and having an annular shape is disposed on a side surface of the sealing gasket 5, the opposite side of sealed pad 5 is provided with rather than concentric setting and is annular second protruding circle 7, first protruding circle 6 and second protruding circle 7 is located respectively the both sides of third through hole, flange 3 with seted up on the connection terminal surface of interface flange 4 with first protruding circle 6 matched with first recess 8, interface flange 4 with seted up on the connection terminal surface of flange 3 with second protruding circle 7 matched with second recess 9, connecting bolt is preferably chooseed for use to the fastener.
