Abstract

The utility model relates to a gas-liquid pipeline rehabilitation machine, and belongs to the field of tools for pipelines. The gas-liquid pipeline rehabilitation machine is provided with oil cylinders and is characterized in that a plurality of oil cylinders are evenly arrayed at intervals along a circumference, the lower end of an extensible rod of each oil cylinder is connected with a shoe pressing block, two adjacent shoe pressing blocks are connected through a shaft pin, the upper end of each extensible rod is connected with a piston, oil cylinder cavities below the adjacent pistons are communicated through a pressure-return oil opening, and oil cylinder cavities above the adjacent pistons are communicated through a pressure-boost oil opening. The gas-liquid pipeline rehabilitation machine is simple in structure and compact in size, rehabilitation working to a whole set of pipelines can be completed quickly in a small space, and meanwhile the rehabilitation machine can work under pressure and with water, the difficult technical problem that working under pressure and with water in a traditional rehabilitation method cannot be achieved is completely overcome, rehabilitation of the pipelines can be easy and fast, the using function of the pipelines can be restored quickly after rehabilitation of the pipelines, and economic loss of residents and mines and other enterprises can be lowered.

Description

Gas-liquid pipeline obturator

Technical field

The utility model relates to the pipeline field of tool, at length says it is a kind of gas-liquid pipeline obturator.

Background technique

As everyone knows, traditional pipeline maintenance must stop to press operation, needs long-time maintenance after the maintenance, could recover the use function of pipeline, when pipeline breaks down, stops pressing the operation meeting that the user is brought unnecessary impact and related economic loss.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of gas-liquid pipeline obturator, and it is long fundamentally to solve the pipeline maintenance cycle, can't be with pressure, the technical barrier of submersible.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of gas-liquid pipeline obturator, be provided with oil cylinder, it is characterized in that, a plurality of oil cylinders are spaced around even circumferential, the flexible rod lower end of each oil cylinder is connected with a shoes briquetting, links to each other by pivot pin between two adjacent shoes briquettings, and the flexible rod upper end is connected with piston, the oil cylinder cavity of adjacent piston below is connected through the back pressure hydraulic fluid port, and the oil cylinder cavity of adjacent piston top is connected through the supercharging hydraulic fluid port.

The beneficial effects of the utility model are, simple in structure, sturdy and durable, volume compact can in less space, be finished rapidly a whole set of pipeline rehabilitation operation, simultaneously, can with pressure, submersible, thoroughly having overcome the traditional maintenance method can not with the technical barrier of water, Operating Pressure, make pipeline maintenance more simple, quick, can recover pipeline after maintenance finishes at once and use function, reduce the loss economy of resident, industrial enterprise.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is structural representation of the present utility model.

1. oil cylinders among the figure, 2. supercharging hydraulic fluid port, 3. shoes briquetting, 4. back pressure hydraulic fluid port, 5. pivot pin, 6. piston.

Embodiment

In Fig. 1, the utility model is provided with oil cylinder 1, a plurality of oil cylinder 1 is spaced around even circumferential, the flexible rod lower end of each oil cylinder 1 is connected with a shoes briquetting 3, link to each other by pivot pin 5 between two adjacent shoes briquettings 3, the flexible rod upper end is connected with piston 6, and the oil cylinder cavity of adjacent piston 6 belows is connected through back pressure hydraulic fluid port 4, and the oil cylinder cavity of adjacent piston 6 tops is connected through supercharging hydraulic fluid port 2.

The utility model is sleeved on the pipeline when using, and then seal rubber pad, steel cover mother is enclosed within the piping failure position successively, and shoes briquetting 3 subtend steels cover is female.The hydraulic workstation hydraulic-pressure pump is exported hydraulic oil by fuel-displaced valve, enter oil cylinder 1 through hydraulic oil pipe, through supercharging hydraulic fluid port 2 beginning mineralization pressures, the piston 6 of hydraulic jack stretches out motion with the shoes briquetting 3 at top, because the effect of external force is with the female reduced of steel cover, make the fault pipeline, the steel cover is female to be close to the seal rubber pad three is airtight, after steel overlaps female stabilization, oil return valve open with hydraulic workstation, make hydraulic oil enter back pressure hydraulic fluid port 4, piston 6 is retracted with shoes briquetting 3 just finish whole process, pivot pin 5 connects shoes briquetting 3 and forms circular integral body, makes active force uniform and stable.
