Abstract
A pipe plug at a water injection end of a pipeline is provided with separating gaskets, sealing rings, a water injection pipe and a clamping nut. An outer end plate and an inner end plate are respectively sleeved at two ends of the water injection pipe; a plurality of sealing rings and separating gaskets are sleeved on the water injection pipe which is arranged between the outer end plate and the inner end plate; one end of the water injection pipe, which is provided with the outer end plate, is connected with a water injection valve through a flange; one end of the water injection pipe, which is connected with the flange, is provided with external threads; and the external threads are provided with the clamping nut which is located at one side of the outer end plate. The pipe plug at the water injection end of the pipeline has the advantages of being simple in structure, convenient to operate, capable of being used for multiple pressure testing mediums to meet requirements of high pressure testing, capable of achieving a water injection function, convenient to achieve integral disassembly and assembly and capable of achieving partial replacement in the case of abrasion, reducing the production costs and improving the economy benefits at the same time.
Description
Technical field
The present invention relates to pipe close, relate in particular to a kind of pipeline water filling end pipe close when water supply line is carried out pressure test.Belong to building fields such as petrochemical industry and municipal water supply.
Background technique
At present, when water supply line was carried out pressure test, water supply line water filling end common structure was the blind flange of band perforate, adopted blind flange to be connected with the end face of flange of pressure testing pipeline, and connected waterflood-transmission line in the perforate of blind flange.Because this structure only is applicable to the pipeline of end face of flange, when running into the pipeline that does not have flange, its straight length will be as pressure testing water filling end, usually need the interim flange of welding, connect the pressure testing blind flange again, after pressure testing finishes, with interim flange and the excision of part straight length.
Existing pipeline pipe close when water supply line is carried out pressure test mainly comprises: two kinds of mechanical expansion-fastening type and shutoff air sac types.Wherein, the volume and weight of mechanical expansion-fastening type pipe close is all bigger, need adjust repeatedly during use.Shutoff air sac type pipe close then needs to be equipped with special high-pressure air source, and, can not realize water filling.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and a kind of pipeline water filling end pipe close is provided, and it is simple in structure, easy to operate, not only can be used for multiple test medium, satisfies the requirement of high pressure pressure testing; And, can realize water filling and shutoff function; Simultaneously, realize integral disassembly, assembly easily, when wearing and tearing take place, may carry out local replacing, reduced cost of production, improved the Economy benefit.
The objective of the invention is to be realized by following technological scheme:
A kind of pipeline water filling end pipe close is characterized in that: be provided with separate spacers, seal ring, water injecting pipe, turnbuckle, wherein, the two ends of water injecting pipe are respectively installed with an outer end plate and inner end plate; Be set with several seal rings and separate spacers on the water injecting pipe between this outer end plate and the inner end plate; The end that the water injecting pipe of outer end plate is installed links to each other with water injection valve by flange, and an end of the water injecting pipe that is connected with flange is provided with outside thread, and turnbuckle is installed on the outside thread, and turnbuckle is positioned at outer end plate one side.
Described seal ring adopts rubber material to make, and separate spacers adopts metallic material to make, and separate spacers is arranged between two adjacent seal rings, and on the same group seal ring is not separated.
Beneficial effect of the present invention: the present invention is owing to adopt technique scheme, and it is simple in structure, easy to operate, not only can be used for multiple test medium, satisfies the requirement of high pressure pressure testing; And, can realize water filling and shutoff function; Simultaneously, realize integral disassembly, assembly easily, when wearing and tearing take place, may carry out local replacing, reduced cost of production, improved the Economy benefit.

Major label description in figure:
1. water injection valve, 2. flange, 3. pad, 4. outer end plate, 5. separate spacers, 6. seal ring, 7. inner end plate, 8. water injecting pipe, 9. turnbuckle, 10. pressure testing pipeline.
Embodiment
As shown in Figure 1, the present invention is provided with pad 3, outer end plate 4, separate spacers 5, seal ring 6, inner end plate 7, water injecting pipe, turnbuckle, and wherein, the two ends of water injecting pipe 8 are respectively installed with an outer end plate 4 and inner end plate 7; Be set with several seal rings 6 and separate spacers 5 on the water injecting pipe 8 between outer end plate 4 and the inner end plate 7; The end that the water injecting pipe 8 of outer end plate 4 is installed links to each other with water injection valve 1 by flange 2, and an end of the water injecting pipe 7 that is connected with flange 2 is provided with outside thread, and turnbuckle 9 and pad 3 are installed on the outside thread, and turnbuckle 9 is positioned at outer end plate 4 one sides; The remaining part of water injecting pipe 8 is smooth surface.
Above-mentioned seal ring 6 adopts rubber materials to make, and separate spacers 5 adopts metallic material to make, and separate spacers 5 is arranged between two adjacent seal rings 6, and on the same group seal ring 6 is not separated, and sticks together under the state of being squeezed to prevent seal ring 6.
Working principle of the present invention: as shown in Figure 2, during use, the present invention is installed in the pressure testing pipeline 10.When turnbuckle 9 was tightened, the distance between inner end plate 7 and the outer end plate 4 was furthered; Simultaneously, after seal ring 6 is squeezed and is out of shape, and the increase of the frictional force between pressure testing pipeline 10 inwalls, thus, realized the shutoff to pressure testing pipeline 10.And the waterflood path when forming pressure testing between the water injection valve 1, flange 2, water injecting pipe 8.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
