Abstract
The utility model relates to a well head packing installs ware additional, including the cassette of joint in sealed ware groove, offered uncoveredly on the cassette, this is uncovered fixes a position the groove joint that the bayonet socket is used for and seals up the ware down for fixing a position down the bayonet socket, is connected with the regulation pole in the cassette rear end, is provided with the axle sleeve on the regulation pole, has worn a pivot in the axle sleeve, the axle sleeve is stretched out at the pivot both ends to stretch out the distolateral depression bar that is connected with two, be provided with packing gland between two depression bars. This application can realize that laborsaving, quick, stable the installing additional of packing pushes down, shortens the packing and installs the time additional, through on -the -spot on probation contrast, can shorten the single and change packing operating time 4 minute, makes to change packing operating efficiency and improve, and oil well production prescription improves. This application is whole being fixed on the packing box when using, and operation process is stable more, safety, when installing the packing additional, packing gland is the face contact with the packing, can not harm the packing.
Description
Technical field
The utility model relates to a kind of well head packing installation device of the oil pumping well head packing that changes the outfit.
Background technology
Along with oil field development is deeply carried out, oil well comprehensive water cut progressively rises, and the wearing and tearing of oil pumping well head packing are in quickening, and the replacing of packing becomes more frequent, because changing downtime that packing causes also in increase, have impact on the production timeliness of rod-pumped well.
The common packing that installs additional operates at present: one is press down with flat mouth bottle opener; Two is press down with " cross instrument ".Because the annular space of polished rod and packing box inwall is narrow and small, packing operates more difficult in process of press in, and common way to be piecemeally progressively pressed into, and mainly there is following problem: it is comparatively sharp 1, to play rim of the mouth, easily causes damage to rubber packing; 2, press down that contact surface is little, pressure is uneven easily causes bottle opener instantaneous sliding motion, cause operator's crank; 3, press down effort, operation is more difficult.
Summary of the invention
The purpose of this utility model is a kind of well head packing installation device that can install well head packing fast additional of design.
The purpose of this utility model is achieved in that well head packing installation device comprises the deck being connected in sealer groove, described deck offer uncovered, this is uncovered is lower limited bayonet, lower limited bayonet is used for, with the groove clamping of sealer, being connected with adjusting rod, adjusting rod upper end is provided with axle sleeve in deck rear end, a rotating shaft is installed with in axle sleeve, axle sleeve is stretched out at described rotating shaft two ends, and stretches out side two and be connected with depression bar, between two depression bars, be provided with packing gland.
Owing to carrying out technique scheme, laborsaving, quick, stable the installing additional that the utility model can realize packing presses down, and shortens packing and adds ETL estimated time of loading, the contrast on probation through scene, can shorten single and change 4 minutes packing operating times, replacing packing operating efficiency is improved, oil well production timeliness improves.The utility model in use entirety is fixed on packing box, and operating process is more stable, safety; When installing packing additional, packing gland and packing are that face contacts, and can not damage packing.
Accompanying drawing illustrates: the technical solution of the utility model is provided by the following drawings and embodiment
Fig. 1 is well head packing installation device structural representation.
Legend: 1, connecting rod, 2, packing gland, 3, upper limited bayonet, 4, depression bar, 5, rotating shaft, 6, card edge, 7, lower limited bayonet, 8, deck, 9, back seat, 10, adjusting rod, 11, axle sleeve.
Embodiment: as shown in Figure 1, well head packing installation device comprises the deck 8 being connected in sealer groove, described deck 8 offers uncovered, this is uncovered is lower limited bayonet 7, and lower limited bayonet 7 is for the groove clamping with sealer, adjusting rod 11 is connected with in deck 8 rear end, adjusting rod 11 upper end is provided with axle sleeve 11, is installed with a rotating shaft 5 in axle sleeve 11, axle sleeve 11 is stretched out at described rotating shaft 5 two ends, and stretch out side two and be connected with depression bar 4, between two depression bars 4, be provided with packing gland 2.
Be connected with back seat 9 in deck 8 rear end, back seat 9 is erect side by side adjusting rod 10.
Described depression bar 4, deck 8 are positioned at the homonymy of adjusting rod 11.The parallel laying of two depression bars 4, can ensure packing uniform force when pressing down packing gland 2 like this, prevents from damaging packing.
Described adjusting rod 11 bottom is screw rod, and itself and back seat 9 spin.By adjusting the height of adjusting rod 11, the distance between packing gland 2 and deck 8 can be adjusted, thus the demand of packing changed by the sealing ring meeting different model.
Described packing gland 2 is for having the annulus of opening, and its both sides, top are fixed between depression bar 4 by connecting rod 1.The opening of described packing gland 2 is upper locating fastener 3, described packing gland 2 lower circumferential with treat pressure-conducting disk root circumference coincide.If when changing the outfit packing, sealer is connected with polished rod, polished rod is positioned at locating fastener 3.
Lower limited bayonet 7 both sides on described deck 8, for card is along 6, is blocked along 6 and are stretched into sealer groove, contact with groove upper and lower end face.
During use, by lower limited bayonet 7 and the clamping of sealer groove, packing is contained in advance sealer upper port place subsequently, lower moulded rod 4, drive packing gland 2 to press packing downwards, packing uniform stressed presses down and puts in place, completes packing and installs.
Above technical characteristic constitutes most preferred embodiment of the present utility model, has best implementation result, can meet the visual effect of valve switch.
