Abstract
The utility model discloses a taking-out tool for a wellhead valve steel ring. The taking-out tool is applicable to taking-out of the wellhead valve steel ring on an oil production and gas production tree at a wellhead of an oil field. One end of a rod is inserted into one end of a central hole of a pushing block and welded, a cylindrical end of a conical head is inserted into the other end of the central hole of the pushing block and welded, sponge is coated on outer walls of the conical head and the pushing block, the other end of the rod is inserted into the central hole at the bottom of a copper bar seat and welded, a cylindrical copper bar is arranged in the copper bar seat, and the outer diameter of the copper bar is equal to the inner diameter of the copper bar seat. The taking-out tool for the wellhead valve steel ring has the advantages that the wellhead valve steel ring on the oil production and gas production tree can be taken down safely and quickly, hidden danger caused by spark is eliminated, requirements for construction quality are met, construction speed and production efficiency are improved, and the tool is easy to process and can be popularized.
Description
Technical field
The utility model relates to oil field operation rig tool technical field, particularly a kind of safe, take off the aid of the well-head valve steel ring on the well mouth of oil well oil recovery christmas tree fast.
Background technology
At present, oil field oil recovery christmas tree is a control head necessary in the petroleum exploration and development, between its flange, the connection of gatehouse all uses steel ring.The long-term use influenced by air, oil, gas, water, wax between steel ring and steel ring slot and can produce corrosion and fouling, only depends on the adjacent side jarring to be difficult to take out, and spanner, pipe wrench kind tool power are grabbed the incessantly inside and outside shiny surface of steel ring for a short time, and power is destroyed the sealing surface of steel ring greatly again.Take out difficulty, cause prolong man-hour; Cause workpiece to damage, cause the blowout out of control risk to increase; In well when operation that contains natural gas, instrument is prone to produce spark with the steel surface bump, is the major hidden danger of blast and fire.
The utility model content
The purpose of the utility model is: provide a kind of well-head valve steel ring to take out instrument, can take off well-head valve steel ring on the oil field oil recovery christmas tree, and can subdue the potential safety hazard that spark produces, increase work efficiency, reduce labour intensity.
The technical scheme that the utility model adopts is: the well-head valve steel ring takes out instrument, comprises conical head, the piece that pushes, the body of rod, copper rod seat, copper rod and sponge.It is characterized in that: the body of rod is the cylinder bodily form, and an end of the body of rod is inserted into the interior and welding of an end of the centre bore of the piece that pushes, and the cylinder end of conical head inserts the interior and welding of another section of the centre bore of the piece that pushes; On the outer wall of the conical head and the piece that pushes, be enclosed with sponge, sponge fully absorbs water, and produces spark when preventing conical head and pushing the piece impact; The described piece that pushes is the hexagon cylinder and centre bore is arranged; One end of conical head is the cylinder bodily form, and the other end is a cone; The other end at the body of rod inserts in the copper rod seat bottom centre hole and welding; Described copper rod seat is that a cylindric end has the end, in the bottom of copper rod seat centre bore is arranged; A tubular copper rod is arranged in the copper rod seat; The external diameter of copper rod is identical with the internal diameter of copper rod seat.The effect of copper rod avoids producing spark during by hammering, and to cause that natural gas dodges quick-fried.
At the two ends of the piece that pushes chamfering outside the circular arc is arranged.
The material of conical head is an alloy steel, and the hardness of conical head can be carried out snaking to the periphery of steel ring apparently higher than steel ring.
The distance that pushes between piece and the copper rod seat is 120~150 millimeters.
The use that summary well-head valve steel ring takes out instrument helps to understand the utility model.After sponge fully absorbs water, utilize the peripheral snaking of conical head to steel ring, Wicresoft makes protruding to the steel ring outer surface; The block alignment that pushes is made protruding steel ring outer surface, the hammering copper rod, and after impact force that the piece that pushes makes progress was greater than the clamping force of ring recess to steel ring, steel ring was boosted taking-up.
The beneficial effect of the utility model: the utility model well-head valve steel ring takes out instrument, can take off well-head valve steel ring on the oil recovery christmas tree safely, fast, and the potential safety hazard that blowout of spark produces has satisfied the construction quality requirement, has improved speed of application and production efficiency.Processing is simple, is beneficial to popularization.
Description of drawings
Fig. 1 is that the utility model well-head valve steel ring takes out the tool construction generalized section.
Among the figure, 1-conical head, the 2-piece that pushes, the 3-body of rod, 4-copper rod seat, 5-copper rod, 6-sponge.
