Abstract
The utility model relates to the pipe joint of a pressure vessel with a flange plate, which is composed of a rubber irregular sealing ring, a circular press cover, the flange plate, and connecting screws. An axial sleeve pipe is arranged on the flange plate, and the end port of the sleeve pipe is engaged with one side of the rubber irregular sealing ring. The pipe joint of a pressure vessel with a flange plate enables the pipelines of different diameters to connect pipelines with corresponding flange plates, pipe components, valves, and equipment, which can save a compensator, and has the advantages of convenient assembly and disassembly and good sealing performance; the pipe joint of a pressure vessel with a flange plate can work with water; the pipe joint of a pressure vessel with a flange plate can be used for connecting under the condition of the poor centering performance of a pipeline and a connected pipeline.
Description
The utility model relates to the pipe coupling of the pressurized container with flange plate, and this piecing devices can use the joint between the pipeline of the metal of garden shape, rigid plastics, cement.
At present, the Placement between the pipeline of pipeline and flange plate, pipe fitting, valve, the equipment mostly is dead and is connected (welding together), connect, long between trouble, left alone without help man-hour when changing; Another kind of Placement is to adopt tray short tube, slotting dish short tube to add expansion bend and connect, this Placement, and the pipe fitting of use is wide in variety, and the execute-in-place inconvenience increases engineering cost.
The purpose of this utility model is to avoid the deficiency in the above prior art, and provide a kind of wide adaptability simple in structure, connection, the reliable and stable piping flange dish piecing devices of sealability, this connection set requires not strict to master and slave pipeline to neutrality.
Formation of the present utility model:
Position, termination at existing pipeline is provided with piping flange dish piecing devices, and its device is made of a special-shaped rubber seal, garden shape gland, flange plate, a several screw.Be provided with a hollow rubber seal washer between the flange plate on flange plate in this device and pipe fitting or valve or the equipment also together by several bolts, packing ring, nut check.
The utility model further specifies middle in conjunction with the accompanying drawings embodiment:
Accompanying drawing is that pipe fitting, valve, equipment are looked sectional structure chart with the master of piping flange dish piecing devices,
In the diagram zero, parts and the explanation of position sequence number thereof:
1, flange plate, 2, gland, 3, screw, 4, nut, 5, the rubber fixing ring, 6, garden shape pipeline, 7, the axial sleeve pipe on the flange plate, 8, connecting bolt, 9, the hollow rubber seal washer, 10, flange plate.
This pipe fitting, valve, equipment mainly are made of flange plate, connecting bolt, packing ring, nut with piping flange dish piecing devices, it is characterized in that:
On the outer diameter tube of the position, termination of garden shape pipeline 6, be provided with a rubber fixing ring 5, on a circle external diameter of 5 and an end face, be provided with a garden shape gland 2, be connected, tighten together by several screws 3 between the flange plate 1 of gland 2 and pipeline 6 outsides, and be provided with hollow rubber seal washer 9 between the flange plate 10 of flange plate 1 and the pipe fitting that needs be connected or valve or equipment and link together by several bolts 8.
Have an axial sleeve pipe 7 on the said flange plate 1, an end of sleeve pipe 7 is an inner conical, and an end male cone (strobilus masculinus) of this inner conical face and rubber fixing ring 5 matches.
The quantity of said several screw 3, several bolt 8, the diameter of looking pipeline 6 can be the 3-48 root.
The material of said gland 2, flange plate 1 can be metal and also can be rigid plastics.
Good effect of the present utility model:
This flange disc joint device can make the pipeline of size diameter be connected with corresponding pipeline, pipe fitting, valve, equipment with ring flange, can save expansion bend, easy accessibility, energy submersible, good seal performance, can also use this device to be connected under the situation of poor with the centering of connected piece at pipeline (that is: the center line decentraction of master and slave pipeline member).
Claims (4)
1, a kind of pipe fitting, valve, equipment mainly are made of flange plate, connecting bolt, packing ring, nut with piping flange dish piecing devices, it is characterized in that:
On the outer diameter tube of the position, termination of garden shape pipeline 6, be provided with a rubber fixing ring 5, on a circle external diameter of 5 and an end face, be provided with a garden shape gland 2, be connected, tighten together by several screws 3 between the flange plate 1 of gland 2 and pipeline 6 outsides.
2, piping flange dish piecing devices according to claim 1 is characterized in that having an axial sleeve pipe 7 on the said flange plate 1, and an end of sleeve pipe 7 is an inner conical, and an end male cone (strobilus masculinus) of this inner conical face and rubber special-shaped seal ring 5 matches.
