Abstract
The utility model relates to a packing gland, in particular to a novel packing gland of an oil production mouth. The utility model adopts a technical scheme that: the packing gland mainly consists of a gland body, a step, an inner hole and a screw hole; the inner hole passing through the gland body from top to bottom is arranged in the gland body; the protruding step is arranged on the outer side of the top part of the gland; and the screw hole is drilled on the step. The packing gland has the advantages of eliminating potential safety hazard in operation of adding a packing, preventing people from being hurt by a falling object, reducing the labour intensity of workers, along with simple structure and convenient operation.
Description
One, technical field:
The utility model relates to a kind of packing pressure cap, particularly a kind of novel oil production well head packing pressure cap.
Two, background technology:
At present, during the on-the-spot replacing in oil field packing, generally adopt iron wire or cloth that packing box is hung on the polished rod eye, need oil pumper must be parked in bottom dead centre, not only safety factor is low, and operation sequence is many, and cause packing box to come off easily, and injure accident by a crashing object, cause personal injury.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of novel oil production well head packing pressure cap is provided, and can avoid injuring by a crashing object accident, causes personal injury.
Its technical scheme is: mainly be made up of pressure cap body, step, endoporus, screw, be provided with in the described pressure cap body and connect endoporus up and down, top outer is provided with outstanding step, is drilled with screw on described step.
The beneficial effects of the utility model are: solved the potential safety hazard that adds in the packing operation, can avoid injuring by a crashing object accident, caused personal injury; In addition, not only simple in structure, and also easy to operate, reduced worker's labour intensity.
Four, description of drawings:
Accompanying drawing 1 is a side structure schematic diagram of the present utility model;
Accompanying drawing 2 is stereograms of the present utility model;
Among the last figure: step (1), endoporus (2), pressure cap body (3), screw (4).
Five, the specific embodiment:
In conjunction with the accompanying drawings 1 and 2, the utility model will be further described:
The utility model mainly is made up of pressure cap body 3, step 1, endoporus 2, screw 4, be provided with in the described pressure cap body 3 and connect endoporus 2 up and down, top outer is provided with outstanding step 1, on described step 1, be drilled with screw 4, a last screw rod in the screw, the length of screw rod and the equal in length of screw, rubber cushion can be equipped with in the inner of screw rod.
During operation, only needing the big packing pressure cap on the packing box is unloaded, is to move on to suitable position on the shallow bid root pressure cap with the utility model, screw rod is tightened, and like this, the large and small pressure cap of packing can not glide, and when finishing the replacing packing, will to packing box, get final product on the large and small pressure cap again.
