Abstract
Double flanges with a replaceable water meter consist of a double-disk jacket, a single-disk jacket, a movable pressure disk, an O-shaped apron and screw bolts. A straight tube is provided on the single-disk jacket, a straight tube jacket mouth is provided on the double-disk jacket, and the straight tube of the single-disk jacket can be suitably inserted into the jacket mouth of the double-disk jacket. The movable pressure disk is nested on the straight tube of the single-disk jacket, the O-shaped apron interpenetrates between the double-disk jacket of the straight tube part of the single-disk jacket and the movable pressure disk, and the movable pressure disk and the double-disk jacket are closely and firmly linked together by the screw bolts. The utility model widely used in various pipeline projects has the advantages of free retractility and reasonable sealing.
Description
The utility model belongs to pipe fitting connecting flange device, particularly relates to a kind of two flanges of interchangeable water meter.
50 millimeters of diameters and above tap water water meter and gate valve adopt two flanges and use Bolt Connection at present, and the straight length that is embedded in underground water supply pipe malleable not, when changing water meter, shed attachment bolt, old water meter is difficult for taking out at every turn, and new water meter is placed on the origin-location, the flat rubber cushion of the sealing at water meter two ends is put into one, and axial float appears in water meter, places two flat rubber cushions and puts to enter again, when radially squeezing into slightly iron with hand hammer between two ring flanges, the ring flange edge ruptures easily.
The purpose of this utility model provides a kind of two flanges of interchangeable water meter, and it can make flange be mounted for scalable and the sealing rational structure, to remedy the deficiency of existing flange mounting structure.
The technical solution of the utility model: a kind of two flanges of interchangeable water meter, it is characterized in that it is made up of double plate cover, single-deck cover, live platen, O type cushion rubber and bolt, said single-deck has put straight tube, double plate has put the straight tube running-on, and the running-on of the straight tube of single-deck cover and double plate cover is can mate plug-in mounting; The platen of living is sleeved on the straight tube of single-deck cover and O type cushion rubber also intert the double plate cover at the straight tube position of single-deck cover with live between the platen, platen alive is connected by bolted with the double plate cover.
Above-mentioned said O type cushion rubber can be that O type side cushion rubber can also be an O type circle cushion rubber.
Superiority of the present utility model is: 1, use this flange component to have flexible freedom, seal rational remarkable advantage, can be widely used in water supply, oil transportation, the various pipework of gas transmission; 2, use this flange component that the indoor water meter of well can radially be rotated, thereby guarantee the horizontal level of dial plate, provide convenience for the metering of checking meter; 3, platen alive in this flange component and double plate cover are fastening by Bolt Connection, make O shape rubber sealing have the hermetically-sealed construction rationality at the straight tube of single-deck cover and the running-on plane of double plate cover; 4, the cover of the double plate in this flange component has bigger morpheme movingly after making up with the single-deck cover, can alleviate the not straight contradiction of tubing that underground tubing produces because of the unequal factor of crustal subsidence.
Below with drawings and Examples explanation the utility model.
Accompanying drawing 1 is two flange arrangement synoptic diagram of the related a kind of interchangeable water meter of the utility model.
Among the figure: 1a is the double plate cover, and 1b is the straight tube running-on that double plate puts, and 2a is the single-deck cover, and 2b is the straight tube that single-deck puts, and 3 are the platen of living, and 4 is O type side cushion rubber, and 5 is bolt.
Embodiment: a kind of two flange (see figure 1)s of interchangeable water meter, it is characterized in that it is made up of double plate cover 1a, single-deck cover 2a, live platen 3, O type side cushion rubber 4 and bolt 5, on the said single-deck cover 2a straight tube 2b is arranged, on the double plate cover 1a straight tube running-on 1b is arranged, the running-on 1b of the straight tube 2b of single-deck cover 2a and double plate cover 1a is can mate plug-in mounting; The straight tube 2b that the platen 3 of living is sleeved on single-deck cover 2a goes up and O type side cushion rubber 4 also intert the double plate cover 1a at the straight tube 2b position of single-deck cover with live between the platen 3, the platen 3 of living overlaps 1a by 5 fastening connections of bolt with double plate.
Claims (2)
1, a kind of two flanges of interchangeable water meter, it is characterized in that it is made up of double plate cover, single-deck cover, live platen, O type cushion rubber and bolt, said single-deck has put straight tube, and double plate has put the straight tube running-on, and the running-on of the straight tube of single-deck cover and double plate cover is can mate plug-in mounting; The platen of living is sleeved on the straight tube of single-deck cover and O type cushion rubber also intert the double plate cover at the straight tube position of single-deck cover with live between the platen, platen alive is connected by bolted with the double plate cover.
2, two flanges of interchangeable water meter according to claim 1 is characterized in that said O type cushion rubber can be that O type side cushion rubber can also be an O type circle cushion rubber.
