Abstract
The utility model belongs to machines and tools used for pipeline plugging operation under pressure and particularly relates to a foldable plug. The foldable plug is composed of a plugging disk, a connecting plate, a connecting pipe, main plates, connecting plates between the main plates, connecting rods, supporting arms, an adjusting bolt, a plugging disk hinge and guide wheels. The foldable plug is characterized in that the plugging disk is composed of a middle petal and two side petals, the plugging hinge is used for connection, one end of one supporting arm and one end of the other one supporting arm are fixed outside the two main plates through movable shafts, and the other ends of the two supporting arms are connected to the two side petals of the plugging disk through movable shafts respectively. One end of one connecting rod and one end of the other connecting rod penetrate through the middles of the two main plates through movable shafts respectively. The other end of one connecting rod and the other end of the other connecting rod respectively penetrate through the connecting plate behind the middle petal of the plugging disk through movable shafts. The connecting pipe is welded to the two main plates in a clamped mode, and three corners of the two main plates are welded through the connecting plates between the main plates. The adjusting bolt is arranged below the space between the two main plates. The two guide wheels are arranged above and below the plugging disk. The foldable plug is suitable for medium-low pressure plugging operation in large pipelines, and the sealing effect is good.
Description
Technical field
The utility model belongs to pipe pressurized shutoff work tool, particularly a kind of folding stopper.
Background technique
When pipe pressurized maintenance operation, after need to ducted liquid or gas being blocked with block head, carry out again maintenance operation, the block head of existing use is circular, need have the shutoff pipe fitting of package size during shutoff, use inconvenient, waste resource, waste of manpower.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of folding stopper, the stifled dish of this folding stopper is to consist of mesopetalum and two side lobes, with stifled dish gemel connection, two support arm one end are fixed on two mainboard outsides with movable axis respectively, the other end is connected on two side lobes of stifled dish with movable axis respectively, two connecting rod one end are through in the middle of two mainboards with movable axis respectively, the other end is through on the connecting plate after the mesopetalum of stifled dish with movable axis respectively, connecting pipe clamp is welded on two mainboards, between three angles of two mainboards, with connecting plate between mainboard, weld, below between two mainboards is provided with adjustment bolt, two upper saw pulleys are in stifled coil upper, below, during shutoff operation, connecting tube is connected with the main shaft on blocking machine, the main shaft of blocking machine moves down stifled dish hinge and opens, stifled dish is for circular, pipe plugging is lived, good sealing effect, shutoff operation is complete, on the main shaft of blocking machine, move, stifled dish hinge is closed, two side lobes of stifled dish turn back.
The technical scheme in the invention for solving the technical problem is: a kind of folding shutoff dish, by stifled dish, connecting plate, connecting tube, mainboard, connecting plate between mainboard, connecting rod, support arm, adjust bolt, stifled dish hinge, upper saw pulley forms, its special way is: stifled dish is to consist of mesopetalum and two side lobes, with stifled dish gemel connection, two support arm one end are fixed on two mainboard outsides with movable axis respectively, the other end is connected on two side lobes of stifled dish with movable axis respectively, two connecting rod one end are through in the middle of two mainboards with movable axis respectively, the other end is through on the connecting plate after the mesopetalum of stifled dish with movable axis respectively, connecting pipe clamp is welded on two mainboards, between three angles of two mainboards, with connecting plate between mainboard, weld, below between two mainboards is provided with adjustment bolt, two upper saw pulleys are in stifled coil upper, below.
The beneficial effects of the utility model are: pipeline tapping is little, are applicable to large-scale pipeline mesolow shutoff operation, good sealing effect, and easy construction, withstand voltage lasting, save manpower and resource.
