Abstract
The utility model discloses a preventer is proclaimed oneself to high pressure, press the cap including the packing box, the packing box is pressed and is being set up the polished rod passageway in the cap middle part, presses to be connected on the cap lateral wall with polished rod passageway looks vertically packing box setting up the seal cover, is located the packing box and presses the vertical through -hole that is setting up on the seal cover of cap, and this through -hole arranges with the polished rod passageway is coaxial that sliding fit is setting up sealed in the seal cover, seal piece also to set up the polished rod passageway, the seal cover constitute by the nickel aluminum bronze, setting up screw plug in the seal cover outside end, in the screw plug terminal surface with sealed piece outside terminal surface between the seal cover in setting up the spring, gland through threaded connection to seal cover outside end, the outer end face centre of screw plug is setting up compression screw, compression screw follows the gland center wear out, setting up carbon packing in the seal cover annular space between gland and the screw plug.
Description
Technical field
This utility model relates to the high-pressure self-sealing preventer of a kind of oil field production and application.
Background technology
The patent No. that the applicant declares is the novel two-stage lubrication self-sealed blow-out preventing device of ZL201520218819.5, and in most of oil wells, result of use is relatively good, is a kind of normal pressure preventer, can't resolve the packing box oil well applications problem adding belt.And this type of well has 5000-6000 mouth at present, cause when light rod-broken large area to run oil contaminated environment, oil field needs a kind of on-line pressure sealant device to solve oil field needs.
Summary of the invention
The purpose of this utility model is in that to provide a kind of high-pressure self-sealing preventer, it is possible to solves oil-well packing box and adds belt oil-leakage-prevention demand, eliminates the problem that this type of oil well large area runs oil contaminated environment.
nullThe purpose of this utility model is realized in，A kind of high-pressure self-sealing preventer，Including packing box pressing cap，Polished rod passage is set in the middle part of packing box pressing cap，The packing box pressing cap sidewall perpendicular with polished rod passage is connected sealing shroud is set，To be positioned on the sealing shroud of packing box pressing cap vertically arranged through hole，This through hole is coaxially arranged with polished rod passage，It is slidably matched in sealing shroud and sealing block is set，Sealing block is also provided with polished rod passage，Described sealing shroud is made up of nickel-aluminum bronze，In sealing shroud outboard end, screw plug is set，In sealing shroud between screw plug inner face and described sealing block end face outside, spring is set，Sealing shroud outboard end is threaded connection gland，Screw plug outer face centrally disposed clamping screw，Clamping screw passes from described gland center，In sealing shroud annular space between gland and screw plug, graphite packing is set.
This utility model adjusts the sealed environment between sealing block and polished rod by clamping screw and spring, by installation graphite packing, sealing shroud end is carried out further dual-seal simultaneously, can solve the problem that oil-well packing box adds belt oil-leakage-prevention demand, eliminate the problem that this type of oil well large area runs oil contaminated environment, improve oil well per unit area yield, reduce crude oil waste, easy to use.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Fig. 1 is that master of the present utility model looks cross-sectional view.
Detailed description of the invention
A kind of high-pressure self-sealing preventer, as shown in Figure 1, including packing box pressing cap 1, polished rod passage is set in the middle part of packing box pressing cap 1, packing box pressing cap 1 sidewall perpendicular with polished rod passage is connected sealing shroud 3 is set, to be positioned on the sealing shroud of packing box pressing cap vertically arranged through hole, this through hole is coaxially arranged with polished rod passage, being slidably matched in sealing shroud and arrange sealing block 2, sealing block 2 is also provided with polished rod passage, polished rod passes from polished rod passage.Described sealing shroud 3 is made up of nickel-aluminum bronze, in sealing shroud 3 outboard end, screw plug is set, spring 4 is set in the sealing shroud between screw plug inner face and described sealing block end face outside, sealing shroud outboard end is threaded connection gland 7, screw plug outer face centrally disposed clamping screw 5, clamping screw 5 passes from described gland 7 center, arranges graphite packing 6 in the sealing shroud annular space between gland and screw plug.
