Abstract

The utility model relates to a jacked-type pressure plugging machine, comprising a connecting clamp (1), a complementary plate (2), a complementary plate feeding shaft (3), a pressure bearing (4), a screw rod (5), a spindle (6), a positioning sleeve (7), a drainage port (8), a rubber pad (9), a reinforcing rib (10) and a handle (11). The jacked-type pressure plugging machine is characterized in that: the whole set of plugging machines are mounted on a pipeline through the connecting clamp (1) which is fastened by a bolt; the spindle (6) and the positioning sleeve (7) are respectively welded at the upper and lower sides of the plugging machine; the spindle (6) is internally provided with the screw rod (5); the pressure bearing (4) is arranged below the screw rod (5); the complementary plate (2) and the complementary plate feeding shaft (3) are welded together; the complementary plate (2) and the rubber pad (9) are spliced with each other. The utility model has the advantages that the jacked-type pressure plugging machine can be applied to leak sources on the pipeline welding line, and is small in volume, large in the plugging area, safe, reliable and simple in structure.

Description

Roof pressing type pressure sealing device

Technical field

Do not stop production when the relating to a kind of pipe-line local leakage device of pressure sealing of the utility model, specifically a kind of roof pressing type pressure sealing device.

Background technique

At present, increasing along with the long oil and gas pipeline of China, corrosive pipeline or alternate manner are to pipeline destroyed, brought great risk for pipeline transport enterprise, when former pressure sealing device had leak source on long oil and gas pipeline, the stopping transportation oil pressure was not implemented the repairing to leak source, but faulty place is arranged also, main performance exists volume excessive in actual use, and the leak stopping area is little, runs into and shortcoming such as can not use when reveal the weld joint.

Summary of the invention

The purpose of this utility model is to provide a kind of volume littler, more withstand voltage, is guaranteeing simpler, more practical pipeline roof pressing type pressure sealing device under the safe and reliable prerequisite.

The technological scheme that its technical problem that solves the utility model adopts is: it comprises connection jig (1), mend plate (2), send and mend plate axle (3), pressure bearing (4), leading screw (5), main shaft (6), abutment sleeve (7), draining hole (8), rubber pad (9), stiffening rib (10), handle (11), it is characterized in that a whole set of leak stopping device being installed on the pipeline by connecting jig (1), it is fastening to use bolt will connect jig (1), main shaft (6) and abutment sleeve (7) are welded on leak stopping device both sides up and down respectively, be provided with leading screw (5) in the main shaft (6), leading screw (5) below is provided with pressure bearing (4), by pressure bearing (4) leading screw (5) bottom is coupled together with sending benefit plate axle (3), again by the woodruff key in the abutment sleeve (7) fixedly make send mend plate axle (3) can be along with the feeding of leading screw (5) is rotated, mend plate (2) and weld together, mend plate (2) and bond together with rubber pad (9) with sending benefit plate axle (3).

The beneficial effects of the utility model are, the utility model is compared with prior art, and this roof pressing type pressure sealing device not only can be applicable to the leak source on the pipe welding seam, and volume is little, and the leak stopping area is big, and is safe and reliable, simple in structure.

Description of drawings

Fig. 1 is an example structure schematic representation of the present utility model;

Fig. 2 is a side-looking structural representation of the present utility model;

Among the figure: connect jig (1), mend plate (2), send and mend plate axle (3), pressure bearing (4), leading screw (5), main shaft (6), abutment sleeve (7), draining hole (8), rubber pad (9), stiffening rib (10), handle (11).

Embodiment

With reference to description of drawings the utility model is done following concrete detailed description; As shown in drawings, concrete structure of the present utility model is by connecting jig (1), mend plate (2), send and mend plate axle (3), pressure bearing (4), leading screw (5), main shaft (6), abutment sleeve (7), draining hole (8), rubber pad (9), stiffening rib (10), handle (11) combines, by connecting jig (1) a whole set of leak stopping device is installed on the pipeline, it is fastening to use bolt will connect jig (1), main shaft (6) and abutment sleeve (7) are welded on leak stopping device both sides up and down respectively, be provided with leading screw (5) in the main shaft (6), leading screw (5) below is provided with pressure bearing (4), by pressure bearing (4) leading screw (5) bottom is coupled together with sending benefit plate axle (3), again by the woodruff key in the abutment sleeve (7) fixedly make send mend plate axle (3) can be along with the feeding of leading screw (5) is rotated, mend plate (2) and weld together, mend plate (2) and bond together with rubber pad (9) with sending benefit plate axle (3).When the oil and gas pipeline stolen (gas) that is perforated, when leak source appears in corrosion failures etc., earlier drainage tube is connected with draining hole (8), drainage tube is put into (gas pipeline in this way in the distance oil saver far away, gas should be lighted), then the leak stopping device directly is buckled on the oil and gas pipeline leak source, the connection jig (1) that carries by the leak stopping device is fastened on the pipeline, rotational lead screw (5) makes mends plate (2) and rubber pad (9) feeding downwards, contact with Pipeline Leakage Point, be rotated further leading screw (5), not leaking outside with leak source oil (gas) is as the criterion, when confirming that oil (gas) nothing leaks outside, plugging device is welded on the pipeline, after welding finishes, is leak stopping device welding end socket, then draining hole is pulled down, welding is installed stops up, so far, whole shutoff process finishes.

Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design concept; common engineers and technicians make the technical solution of the utility model in related domain various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
