Abstract
The invention relates to a seal nut, which is composed of a nut base body and a seal ring. A shallow groove is dug on the inner side of the tail portion of the nut base body and used for installing the seal ring, the free end of the shallow groove is provided with an arc hook portion capable of preventing the seal ring from falling out of the inside of the shallow groove, and the ring thickness of the seal ring is larger than the depth of the shallow groove. The seal ring is arranged on the seal nut, thereby being convenient to use and install. Seal materials are high in corrosion resistance and can be resistant to strong corrosive media including acid, alkali and the like and various oils, and the seal nut can be applied to different environments as long as the materials of the nut base body are changed. The seal nut has an anti-loosening function besides seal performance.
Description
Technical field
The invention belongs to mechanical manufacturing field, particularly a kind of sealing nut.
Background technique
Aero-Space and chemical industry container and seal for pipe joints connection need double thread to connect outer the sealing, and sealing part requirement simultaneously is corrosion-resistant, and present seal rings or the alternate manners of adopting seal more, and this mode complex structure is installed inconvenience.Therefore need a kind of effectively sealing thread joint, corrosion-resistant again, Aero-Space and the matching requirements of chemical industry container are satisfied in installation testing simultaneously nut easily.
Summary of the invention
The technical problem that will solve of the present invention provides a kind of sealing nut with sealing function.
A kind of sealing nut is made up of basal body of nut, seal ring; Shallow trench has been dug in inboard at the basal body of nut afterbody, is used to install seal ring, is provided with the arc hook part at the free end of shallow trench, and the arc hook part can prevent that seal ring from deviating from shallow trench; The ring of seal ring is thick should be greater than the degree of depth of shallow trench.
Be with seal ring on the sealing nut, easy to install, the sealing material corrosion resistance is strong, and strong corrosive medium and all kinds of oil plants such as ability acid resistant alkali can be used for varying environment as long as change the basal body of nut material.Except that having sealing, the present invention also has locking effect.
Description of drawings
Fig. 1 is the structural representation of sealing nut of the present invention;
Embodiment
The objective of the invention is to; Adopt stainless steel or other structural steel as basal body of nut 1, a polytetrafluoroethylene seal ring is installed in basal body of nut 1 as seal arrangement, when this nut uses through cooperating with bolt; When reaching mounting torque; Seal ring is installed end face and bolt shank and is all sealed by pressure solution, also has locking effect simultaneously.
As shown in Figure 1, sealing nut is made up of basal body of nut 1, seal ring 2.Shallow trench 3 has been dug in inboard at the afterbody 5 of basal body of nut 1, is used to install seal ring 2, is provided with arc hook part 4 at the free end of shallow trench 3, and arc hook part 4 can prevent that seal ring 2 from deviating from shallow trench 3.The ring of seal ring 2 is thick should be greater than the degree of depth of shallow trench 3.
The present invention selects Austenitic Stainless Steel processing basal body of nut 1 for use; On nut inner thread, being coated with the MoS2 dry lubricant prevents killing; Seal ring 2 adopts polytetrafluoroethylene materials processing; Can be made into the sealing nut of all size, the container or the pipeline that are widely used in chemical industry or military industry acid resistant alkali medium connect.
