In the prior art scheme, nuclear power station basket formula filter and valve interior wall are not provided with any potted component, and its impurity often flows out through the edge of filter screen, and its filter effect does not have the requirement of method Full foot protection water pump safe operation.The more important thing is by the pressure drop of filtering later medium has strict requirement, otherwise can make water pump generation cavitation damage, water pump can not be worked, thereby force power plant's generation outage.
In the prior art scheme, asbestos washer is installed at the valve gap place usually, there are a lot of shortcomings in asbestos washer, wash away the lower gasket attenuate through using for many years at water, in a single day final leakage the, asbestos washer are revealed and just can only be checked card son or change pad, and sealing surface must be handled totally when changing pad, asbestos are bonded at and are not easy the place that processing, particularly pipeline can not be shifted on the sealing surface.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of nuclear power station basket formula filter that prevents that impurity from flowing out from the gap between filter screen and the valve interior wall that has is provided.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of nuclear power station basket formula filter comprises valve body, valve gap and filter cylinder, and filter cylinder is positioned at valve body, and the junction of described filter cylinder edge, upper end and valve interior wall is provided with gasket seal.
Further technical scheme is that described filter cylinder upper end is the oblique section, and the edge of this oblique section and the junction of valve interior wall are provided with gasket seal.
As the optimal technical scheme of pad, described pad is the metallic graphite carbon spirotallic gasket.
Be connected with handle on the oblique section that further technical scheme is described filter cylinder, valve gap is run through in this handle upper end.
Further technical scheme is the top that described valve gap is positioned at valve body, valve gap be provided with pad between valve body is connected.
The pairing valve body of described again filter screen bottom is provided with mudhole, and mudhole is connected with blow-off line, and blow-off line is provided with by-pass valve control.
The technical program can also be that described valve gap is provided with lifting bolt.
Compared with prior art, the beneficial effects of the utility model are:
The gasket seal of technical solutions of the utility model by being provided with makes impurity can not flow out along the gap, and filter effect is better; The bottom of valve body is provided with mudhole and blow-off line, is used to discharge impurity and pollutant; And be provided with the metallic graphite carbon spirotallic gasket between valve body and the valve gap, the metallic graphite carbon spirotallic gasket has good anti-leak performance, and changes conveniently, can reduce or stop to leak by increasing tight power; Valve gap is provided with lifting bolt, can play the effect of convenient in carrying.
The more important thing is that by the increase flow area, thereby assurance guarantees to make water pump that cavitation not take place by the pressure drop of the medium of filter, guarantees unit safety operation in the tolerance band of design.
The utility model is installed in the big solid impurity that can remove on the pipeline in the fluid, makes machinery equipment, as compressor, pump etc., instrument energy operate as normal and running, reaches stabilizing technical processes, the effect that guarantees safe production.
