Abstract
The utility model relates to a filter type metal spiral wound gasket which is characterized by comprising a centring ring, a strengthening ring and a filter screen, wherein filler is arranged between the centring ring and the strengthening ring; and one layer of filter screen or multiple layers of filter screens are fixedly connected on the strengthening ring. The filter type metal spiral wound gasket has the benefits that the gasket can be used for the initial stage of pipeline production, is arranged between the adjacent flanges at the upstream of a voltage regulating and metering device and comprehensively gives play to the sealing and filtering functions, so as to prevent impurities from damaging the core device.
Description
Technical field
The utility model belongs to pipeline and connects pad, relates in particular to a kind of filter-type SW with outside ring.
Background technology
In fuel gas transportation pipeline and relevant device, nucleus equipments such as pressure regulator, flowmeter are all relatively responsive to the impurity that delivery of fuel gas in the pipeline exists, especially large granular impurity.Can contain a large amount of welding slags and other solid particle polluters in the pipeline operation initial stage pipeline, be very easy to make these nucleus equipments to damage.Demand releasing a kind of filter mechanism of simple possible in the industry urgently, to avoid the destruction of impurity to nucleus equipment.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of filter-type SW with outside ring to be provided, be used for pipeline and go into operation the initial stage, be installed between pressure regulation, the measuring equipment upper reaches adjacent flanges, comprehensively bringing into play its sealing and filtration.
The utility model is for realizing above-mentioned purpose; Realize that through following technical scheme a kind of filter-type SW with outside ring is characterized in that: comprise centering ring, reinforcing ring and filter screen; Be provided with filler, affixed one or more layers filter screen on the said reinforcing ring between said centering ring and the reinforcing ring.
Beneficial effect: be used for pipeline and go into operation the initial stage, be installed between pressure regulation, the measuring equipment upper reaches adjacent flanges, comprehensively bring into play its sealing and filtration, to avoid the destruction of impurity to nucleus equipment.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with preferred embodiment, details are as follows to the specific embodiment that provides according to the utility model: see accompanying drawing for details, a kind of filter-type SW with outside ring comprises centering ring 1, aligns with pipe centerline when being used to install; Reinforcing ring 3 and filter screen are provided with filler 2 between said centering ring and the reinforcing ring, and filler is compacted during installation, seal, and easy deformation behind the filler pressurized, reinforcing ring plays booster action to filler; Affixed one or more layers filter screen 4 on the said reinforcing ring, filter screen makes it have filtering function.Filter screen and reinforcing ring adopt welding manner to fix, and are used for the larger particles impurity in the filter pipe, the safety of protection downstream nucleus equipment.
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
Claims (1)
1. a filter-type SW with outside ring is characterized in that: comprise centering ring, reinforcing ring and filter screen, be provided with filler, affixed one or more layers filter screen on the said reinforcing ring between said centering ring and the reinforcing ring.
