Abstract
The utility model relates to the pipe joint of a pressure vessel with a flange plate. A glandless flange connection device for a pipeline can be used at a joint between the circular pipeline of metal, rigid plastics, and cement and the flange plate of equipment. The glandless flange connection device is mainly composed of a rubber seal air ring with an end housing, a rubber seal barrel with an outer conical shape, a heteromorphic flange plate with an end housing and a conical barrel, connecting bolts, a gasket, and nuts. The rubber seal air ring and the rubber seal barrel can be made into a one-body element, and can also be made into a two-body element. When the glandless flange connection device is connected with the flange plate of equipment, a common compensator can be saved; the glandless flange connection device can work with water. The utility model has the advantages of low labor intensity, simple structure, quick connection, and good sealing performance.
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 flange plate of the pipeline of the metal of garden shape, rigid plastics, cement and equipment.
At present, annexes such as the pipe fitting of pipeline and flanged dish, equipment, valve are connected and mostly are welding, or with the tray short tube, insert the dish short tube and add expansion bend and connect.This Placement uses pipe fitting wide in variety, existing field boundary inconvenient operation, the corresponding engineering cost that increased.
The purpose of this utility model is to avoid the deficiency in the above prior art, and a kind of simple in structure, easy to connect, good seal performance, the corresponding low non-bonnet (NB) flanged ends device of cost are provided.
Formation of the present utility model:
The outside of the garden shape pipeline of these piecing devices is an external conical shape rubber seal tube, the outside of rubber seal tube is a flange plate that has inner conical-tube, is provided with rubber seal annular pad between the pipeline of this flange plate and existing flanged dish, pipe fitting, valve, the equipment and links together by connecting bolt, spring washer, nut.Rubber seal annular pad in this piecing devices, external conical shape rubber seal tube can be made as integral piece, also can be made as two body spares.Saved the gland of extruding rubber seal in these piecing devices, please referring to ZL94244012.9, two patents of ZL94223083.3.
The utility model further specifies middle in conjunction with the accompanying drawings embodiment:
To be pipeline look sectional structure chart with the master of non-bonnet (NB) flanged ends device with accompanying drawing.
In the diagram zero, parts and position sequence number thereof:
1, the flange plate on existing pipeline, pipe fitting, valve, the equipment, 2, fill up with the rubber seal annular end between the flange plate, 3, special-shaped flange plate, 4, external conical shape rubber seal tube, 5, the inner conical tube of flange plate, 6, Oil, Water, Gas, pipeline, 7, rubber gasket 2, tube 4 intersection connecting line.
This pipeline mainly is made of flange plate, connecting bolt, packing ring, nut with non-bonnet (NB) flanged ends device,
By connecting bolt and flange plate 1 match for special-shaped flange plate 3, its dish 1, be provided with rubber seal annular pad 2 between 3, flange plate 3 is provided with inner conical-tube 5, be provided with external conical shape rubber seal tube 4 between the inside of the outside of pipeline 6, flange plate inner conical-tube 5, its tube 4 is located on the rubber seal annular pad 2.
Both can be made as same integral piece said rubber gasket 2, rubber seal tube 4, also can be made as two body spares of pad 2, tube 4 by the connecting line 7 at 45 ° of inclination angles.
The material of said special-shaped flange plate 3 can be metal, also can be rigid plastics.
Good effect of the present utility model:
These piecing devices can make garden shape pipeline and various pipeline with ring flange, pipe fitting, Valve, equipment connect, and can save expansion bend commonly used when connecting, and can be with water to do Already, low, the good seal performance of labour intensity, connection rapidly simple in structure, cost is also corresponding Reduce.
