Abstract
The utility model relates to a removable aeration sealing plug which comprises a rubber airtight pad, The removable aeration sealing plug is characterized by comprising an anchor-shaped steel ring used as an aeration sealing skeleton, wherein the exterior of the circumference of the upper part of an anchor hook of the anchor-shaped steel ring is provided with rubber airtight pads, and the rubber airtight pads are closely connected with the circumference of the upper part of the anchor hook of the anchor-shaped steel ring. According to the removable aeration sealing plug provided by the utility model, the middle of the aeration sealing plug is inflated, the removable aeration sealing plug can temporarily seal wide openings such as towers, tanks and grooves, the sealing effect is good, the removable aeration sealing plug has wide applicable caliber range, and the movement as well as the displacement and disassembly are convenient.
Description
Technical field
The utility model relates to seal arrangement, and particularly, the utility model relates to a kind of movably gas-flow closure plug.Described gas-flow closure plug middle part can be inflated, and can carry out provisional sealing to open ports such as tower, tank, grooves, its good sealing effect, and applicable bore scope is wide, can the conveniently moving dismounting.
Background technique
The gas-flow closure plug can be used for the open ports such as tower, tank, groove are carried out provisional sealing, requires its good sealing effect, and applicable bore scope is wide, and can the conveniently moving dismounting.
The patent No. is that the utility model patent that " 95209544.0 ", name are called " inlet sealing plug for steam generator " discloses a kind of sealing plug, but the sealing plug structure is excessive, steam raising plant is contained in inside, therefore be not suitable in the chemical industry, and, lack maneuverability in its tower tank groove maintenance.In addition, the steam inflation is used in the sealing of this whole device inflation, easily causes unnecessary system's band water.
The patent No. is that " 200820179199.9 ", name are called that " utility model patent of Inflatable closure plug discloses a kind of sealing plug; the sealing plug is designed to the gas-flow closure plug of straight cylinder type; this can not be applicable to the different bore scope of each equipment room of chemical industry equally; seal such as the manhole of need to different size, then easily causes the waste of unnecessary equipment.
In addition, when the device of not finding similar structure in the present existing patent can be used in the sealing of uncovered manhole, carry out the sealing of charging arm in the time of also filling of tank cars can being used in.
The model utility content
For overcoming the problems referred to above, the utility model purpose is, a kind of movably gas-flow closure plug is provided, and described a kind of movably gas-flow closure plug is that a kind of sealing principle is simple, the packed-piston that Applicable scope is extensive.When packed-piston of the present utility model is specially adapted to the maintenance of chemical industry, the temporary sealing of vehicle opening when the sealing of manhole and product loading and unloading are dispatched from the factory.
A kind of movably gas-flow closure plug technological scheme of the present utility model is as follows:
A kind of movably gas-flow closure plug, comprise the rubber air packing, it is characterized in that, described movably gas-flow closure plug also comprises: as the anchor shape steel ring of described gas-flow closure plug skeleton, described anchor shape steel ring below is formed be used to the grasp of filling in the manhole that needs sealing, described grasp upper periphery edge is provided with the rubber air packing, and the grasp top periphery of described rubber air packing and described anchor shape steel ring is fitted.
Thus, can inflate venting seals.
According to removable pneumatic sealing plug of the present utility model, it is characterized in that, the grasp top of described anchor shape steel ring is fixedly connected with flat board, and the loading and unloading suspension ring are set on the flat board.
According to removable pneumatic sealing plug of the present utility model, it is characterized in that, described rubber air packing top of fitting with the grasp top periphery of anchor shape steel ring is provided with air valve.
According to removable pneumatic sealing plug of the present utility model, it is characterized in that, described rubber air packing of fitting with the grasp top periphery of anchor shape steel ring extends to the grasp middle part downwards.
According to removable pneumatic sealing plug of the present utility model, it is characterized in that, described air valve runs through on the flat board that is arranged at grasp top.
According to removable pneumatic sealing plug of the present utility model, it is characterized in that, described grasp is del.
During use, the piston that at first with grasp is del is filled in the manhole that needs sealing, then pour air from the inflation inlet that runs through the air valve on the flat board that is arranged at grasp top, so that the rubber air packing expands, the rubber air packing can be so that rubber sheet gasket and Manhole Sealing Joints agree with after expanding, preventing effectively that internal gas is excessive spills, and only need to exit during dismounting to fall piston and draw off and get final product.The utility model is simple to operation.
Description of drawings
Figure 1 shows that movably gas-flow closure plug schematic diagram of the present utility model.
Among the figure, 1 is the suspension ring of installing/dismounting, and 2 is the inflated rubber gasket, and 3 is charging valve, and 4 is the internal steel skeleton, and 5 is grasp.
Embodiment
Below, for embodiment, specify movably gas-flow closure plug of the present utility model.
Embodiment 1
A kind of movably gas-flow closure plug, comprise the rubber air packing, anchor shape steel ring as described gas-flow closure plug skeleton, described anchor shape steel ring below is formed be used to the grasp of filling in the manhole that needs sealing, described grasp upper periphery edge is provided with the rubber air packing, and the grasp top peripheral shape of described rubber air packing and described anchor shape steel ring is fitted.Described rubber air packing of fitting with the grasp top periphery of anchor shape steel ring extends to the grasp middle part downwards.
Described anchor shape steel ring cross section is circular, and its grasp top is fixedly connected with flat board, and the loading and unloading suspension ring are set on the flat board.Simultaneously, be used for the air valve of gas-flow closure plug inflation is run through the flat board that is arranged at grasp top.In the present embodiment, described grasp is del.
When using this piston to seal, at first piston is filled in the manhole that needs sealing, then pour air from inflation inlet, so that the rubber air packing expands, can be so that rubber sheet gasket and Manhole Sealing Joints agree with after the expansion, preventing effectively that internal gas is excessive spills, and only need to exit during dismounting to fall piston and draw off and get final product, simple to operation.
When packed-piston of the present utility model is specially adapted to the maintenance of chemical industry, the temporary sealing of vehicle opening when the sealing of manhole and product loading and unloading are dispatched from the factory.
