Description
Technical Field
The utility model relates to a mechanical equipment field relates to an oil pipe blanking plug particularly.
Background
The blanking plug is often used in the construction and the maintenance of the pipeline in the oil field, the blanking plug is placed at the position of a pipeline opening needing to be blocked during use, the length of the placed pipeline is the length of the blanking plug, and then compressed air is injected to the specified pressure through the air inlet valve, so that the maintenance can be carried out. The existing oil pipe blanking plug is complex in design, high in cost, complex and tedious in operation, poor in working stability and not suitable for being used in small-size maintenance of oil field pipelines.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides an oil pipe blanking plug, and structural design is simple, low cost, and the reliable operation, operation are very simple and convenient, are fit for using when the small-size maintenance of oil field pipeline.
In order to achieve the above object, the present invention provides the following technical solutions:
the oil pipe blanking plug comprises a cylindrical plug sleeve with an open end, a plugging air bag is fixed in the plug sleeve and extends out of the open end of the plug sleeve, an end plate is arranged at the end part of the plugging air bag, a layer of elastic protection layer is arranged between the end plate and the plug sleeve to wrap the plugging air bag, a tubular vent pipe is communicated with the center of the sealing end of the plug sleeve and is communicated with the sealing of the plugging air bag, a remote control electromagnetic valve is installed on the vent pipe, and a plurality of annular hanging rings are arranged at the sealing end of the plug sleeve.
As the further optimization of the technical scheme, the plug sleeve, the end plate and the vent pipe are all made of stainless steel, and the plug sleeve is connected with the vent pipe through welding.
As a further optimization of the technical scheme, the plugging air bag is made of a rubber material and is connected with the plug sleeve and the end plate through an adhesive.
As a further optimization of the technical scheme, the elastic protective layer is made of hard elastic cloth and is connected with the plug sleeve and the end plate through an adhesive.
As a further optimization of the technical scheme, the lifting rings are all made of stainless steel and are all connected with the plug sleeves through welding.
The beneficial effect of adopting above technical scheme is: when the oil pipe blanking plug is used, the rope can be tied on the hanging ring, and a conveying pipe of the air compressor is communicated with the vent pipe in a sealing mode. And (5) putting down the rope to place the plug sleeve and the plugging air bag at a proper position of the underground pipeline of the oil field. The air compressor inflates the vent pipe to force the plugging air bag to expand to enable the elastic protection layer to prop against the inner wall of the underground pipeline, so that the aim of plugging the underground pipeline of the oil field is fulfilled, and maintenance and construction can be carried out. And the vent pipe is disconnected, so that the air of the plugging air bag can be discharged, and the oil pipe plug can be smoothly withdrawn from the pipeline. The oil pipe blanking plug is simple in structural design, low in cost, reliable in work, very simple and convenient to operate and suitable for being used in small-sized maintenance of oil field pipelines.
