Abstract
The utility model discloses a tapered screw assistant sealing device, comprising a tapered plug, an end face sealing screw sleeve, and a combining sealing pad, wherein the end sealing screw sleeve is arranged on screw thread in the middle of the tapered plug; the outer end face of the end sealing screw sleeve is provided with a combining sealing pad; and when used, the tapered screw assistant sealing device is screwed on a tapered screw hole and forms the end face sealing through the tightly joint among a machine processing surface on the outer end of the tapered screw hole, an outer end face of the end face sealing screw sleeve, and the combining sealing pad, thereby solving the oil leakage problem of the tapered screw thread connection, and making the utility model have more reliable and better sealing capability, simple manufacturing, environmental protection and sanitation, and more convenient operation.
Description
Technical field
The utility model relates to a kind of awl screw auxiliary sealing device that is converted to end face seal by the tapered thread sealing.
Background technique
In engine building, the oily point of attachment of a lot of mistakes all adopts the tapered thread sealing, and the component that also need assemble other after some measuring instruments, tapered plug or the test need be loaded onto in some position when engine test, be coated with the sealer assembling as before test, adopting, after solidifying, sealer just is difficult to pull down the tapered plug of measuring instrument or shutoff screw, simultaneously recoat the poorly sealed phenomenon in sealer assembling back, do not allow to be coated with sealer before solid the test and assemble in the connection place because the difficult cleaning of the cull of screw causes; As adopt raw meal belt to twine sealing, and then have the hidden danger of quality that pollutes, stops up oil duct, and after pulling down the associated part that is assemblied in screw, the raw meal belt that remains in the screw being difficult to cleaning, also can cause to recoat the poorly sealed hidden danger of quality in sealer assembling back; As not taking seal approach in process of the test, even twist tapered plug to such an extent that tightly also can't effectively seal again and produce seepage, coherent detection is inaccurate and pollute Engine Surface when causing test.
Summary of the invention
Technical solution of the present utility model is such, it is a kind of on original tapered plug basis that the purpose of this utility model is to provide, increase the swivel nut and the combination seal pad that are convertible into end face seal and form solution tapered thread connection leakage of oil, make sealing reliable, and it is easy to manufacture, fitting operation is easy to use, the awl screw auxiliary sealing device of environmental protection sanitary.Comprise tapered plug, end face seal cover, combination seal pad.Feature is that tapered plug is set with the end face seal cover outward, between the end face of end face seal cover and the body end face combination seal pad is housed, and the threaded body termination of tapered plug is contained in the awl screw.
Tapered plug termination external diameter has tapered thread and middle part that flat thread is arranged, and tapered thread and flat thread are twisted and inserted body awl screw, awl screw and the engagement of tapered plug outer cone thread, and flat thread connects with the end face seal cover.Use the thread locking adhesive sealed attachment between the two, also available combination seal rubber pad sealed attachment.The endoporus unthreaded hole of awl screw and tapered plug, inner bolt hole connect.
The flat thread engagement of the inner bolt hole of end face seal cover and tapered plug is tightly connected with thread locking adhesive, also available combination sealing gasket sealed attachment between the two.Unthreaded hole, the inner bolt hole of end face seal cover connect.
Tapered plug exposes the summation of tapered thread length L less than the effectively degree of tightening of the thickness of combination seal pad and tapered thread.
The utility model has the advantages that,, solved tapered thread and connected the leakage of oil problem that make sealing more reliable, better tightness has advantages such as easy to manufacture, easy to operate, environmental protection sanitary by the tapered thread sealing is converted to end face seal.
