Abstract
The utility model relates to an electromagnetic shielding waveguide filter, which can be used in places required to carry out electromagnetic shielding, such as precise instrument and meter rooms, meter checking rooms, computer rooms, etc. The electromagnetic shielding waveguide filter is used for preventing electromagnetic wave from radiating interference of electromagnetic wave towards inside or outside of rooms through pipelines when various electromagnetic shielding rooms use the water pipelines. The electromagnetic shielding waveguide filter is composed of a tubular shell body (1), a filtering inner core (2), a pipe hoop (3), an insulating pipe (4) and a diameter changing pipe hoop (5). The long direction of the filtering inner core is distributed with phi 8 mm circular holes which are arranged into honeycomb shape and are provided with zinc coating layers. The development of the electromagnetic shielding waveguide filter solves the problem that the electromagnetic wave can not radiate interference towards inside and outside of the rooms through pipelines when various electromagnetic shielding rooms are provided with heating pipelines. The winter heating cost of the shielding rooms is reduced; the investment cost for building large shielding rooms is reduced.
Description
The utility model relates to a kind of electromagnetic shielding waveguide filter, and it is applicable to the precision instrumentation chamber, the instrument check chamber, and computer floors etc. need carry out the place of electromagnetic shielding.When being used for all kinds of EM shielded room and using the caliducts heating, stop electromagnetic wave by pipeline to indoor or to the Electromagnetic Interference of outdoor radiation.In like manner this electromagnetic shielding waveguide filter also be applicable to stop when all kinds of EM shielded room are used running water electromagnetic wave by pipeline to indoor or to the Electromagnetic Interference of outdoor radiation.
EM shielded room is used the problem that air-conditioning send the method for dim wind to solve warming mostly at present, the use cost height, and technical sophistication, and indoor temperature does not reach instructions for use.A lot of applying units require to use simultaneously common caliduct heating, can satisfy the heating requirement like this, reduce use cost.But present EM shielded room can not get using the application of caliduct heating, and reason is not have this filter to solve the problem that shielded enclosure uses the caliduct heating in the market.
The purpose of this utility model is to propose a kind of electromagnetic shielding waveguide filter, and when using common caliduct heating the winter that solves all kinds of large-scale EM shielded room, electromagnetic wave can not be by pipeline to indoor or to outdoor interference problem of carrying out electromagenetic wave radiation.
The purpose of this utility model is achieved in that a kind of electromagnetic shielding waveguide filter is by tubular shell (1), filtering inner core (2), pipe collar (3), insulated tube (4), reducing pipe collar (5) is formed, filtering inner core (2) is the cylindrical steel equipment structure, vertically be furnished with the circular hole of Φ 8mm and be arranged in cellular, distance is 2mm between circular hole and the circular hole, filtering inner core (2) outer wall has zinc coat, and be welded on 1/4th places, tubular shell (1) right-hand member inboard, there is screw thread at tubular shell (1) two ends, and with good with insulation, intensity is higher, the insulated tube that resistant to elevated temperatures polytetrafluoroethylmaterial material is made (4) carries out threaded connection by pipe collar (3), also has reducing pipe collar (5) to be connected between the insulated tube at two ends (4) and the caliduct.
The drawing explanation:
Fig. 1 is the utility model structural representation, 1 tubular shell wherein, 2 filtering inner cores, 3 pipe collars, 4 insulated tubes, 5 reducing pipe collars.
Fig. 2 is the A-A profile of Fig. 1.
Structural representation when Fig. 3 uses for the utility model, the wherein body of wall of screen 8 EM shielded room of 6 electromagnetic shielding waveguide filters, 7 EM shielded room.
In conjunction with the accompanying drawings structure of the present utility model is specifically described:
The utility model is a kind of electromagnetic shielding waveguide filter, and its production cost is low, handling ease.The structure of waveguide filter is by tubular shell (1), filtering inner core (2), and pipe collar (3), insulated tube (4) and reducing pipe collar (5) are formed.Tubular shell (1) is made with common coating steel pipe, and the selection of caliber is amplified two-stage to the diameter of the caliduct that is used, can select for use the coating steel pipe of Φ 80mm to do housing when being Φ 50mm as the caliduct diameter.Filtering inner core (2) is the cylindrical steel equipment structure, vertically be furnished with the circular hole of Φ 8mm and be arranged in cellular, distance is 2mm between circular hole and the circular hole, filtering inner core (2) outer wall has zinc coat, and be welded on 1/4th places, tubular shell (1) right-hand member inboard, there is screw thread at tubular shell (1) two ends, with good with insulation, intensity is higher, the insulated tube that resistant to elevated temperatures polytetrafluoroethylmaterial material is made (4) carries out threaded connection by pipe collar (3), also has reducing pipe collar (5) to be connected between the insulated tube at two ends (4) and the caliduct.The electromagnetic shielding waveguide filter in use should be good with the welding of the screen (7) of EM shielded room body of wall (8) inwall, can not be by pipeline to indoor or to the outdoor interference of carrying out electromagenetic wave radiation thereby reach electromagnetic wave.
The utility model has solved all kinds of EM shielded room in this field when caliduct is installed, stop electromagnetic wave by pipeline to indoor or to outdoor interference problem of carrying out electromagenetic wave radiation, greatly reduce the expense of large-scale shielded enclosure warming, reduced the investment cost of building large-scale shielded enclosure.The product handling ease of this electromagnetic shielding waveguide filter, reliable in quality.With standard machinery processing, reduced the cost of producing the electromagnetic shielding waveguide filter.
