Abstract
The invention discloses a special nut for a steam boiler. The special nut for the steam boiler comprises a nut main body, wherein the nut main body is a hexagonal nut, a threaded hole is formed in the center of the nut main body in a penetrating manner, an internal thread is arranged on the inner side wall of the threaded hole, frosted carbon fibers are arranged on the ring wall of the internal thread, the internal thread is bulged on a frosted carbon fiber surface by 8 to 15 mm, a chamfered edge wall is arranged on the outer side of the nut main body, polished and then plated with chrome. According to the invention, the friction force of the outer ring and the surface of the inner ring of the nut can be increased, the nut is corrosion resistant, moisture-proof, high-temperature resistant and skid-proof, is suitable for the steam boiler, and not only can resist high-temperature steam, but also has difficulty in loosing for abrasion.
Description
Technical field
The present invention relates to nut field, particularly relate to a kind of steam boiler specialized nut.
Background technology
Nut is exactly nut, is threaded together the part for playing the role of fastening with bolt or screw rod, all manufacturings machinery must a kind of element according to the difference of material, be divided into several big types such as carbon steel, rustless steel, non-ferrous metal (such as copper).Nut is the part got up by plant equipment compact siro spinning technology, and by the screw thread of inner side, equivalent specifications nuts and bolt just can link together.Nut is available for plurality of devices and uses, but must be adaptive by specific nut ability for the nut on special equipment, nut on steam boiler is also to fasten with specific nut, but traditional steam boiler nut corrosion resistance, moisture resistance and heat-resisting quantity are poor, the situation having corrosive wear after long-time use occurs, and have impact on the service life of nut.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of steam boiler specialized nut, by increasing capacitance it is possible to increase the friction dynamics of nut outer ring and inner peripheral surface, nut is corrosion-resistant, moistureproof, high temperature resistant and anti-skidding, it is adaptable to steam boiler.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of steam boiler specialized nut, including nut body, described nut body is hex nut, described nut body central authorities offer screwed hole, described screwed hole is offered on described nut body, described screwed hole medial wall is provided with female thread, described female thread circle wall is provided with frosted carbon fiber, described female thread protrudes frosted carbon fiber face 8-15mm, being provided with incline wall, polishing on described incline wall outside described nut body, after the polishing of described incline wall, chromium plating processes.
In a preferred embodiment of the present invention, frosted carbon fiber is fixed on described female thread circle wall by the way of spraying.
In a preferred embodiment of the present invention, the upthrow light frosted of described nut body upper and lower end face processes, and described nut body upper and lower end face also is provided with frosted carbon fiber.
The invention has the beneficial effects as follows: the present invention can increase the friction dynamics of nut outer ring and inner peripheral surface, nut is corrosion-resistant, moistureproof, high temperature resistant and anti-skidding, it is adaptable to steam boiler, not only high temperature steam, and the most easy to wear and loosening.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of steam boiler specialized nut one of the present invention preferred embodiment；
In accompanying drawing, the labelling of each parts is as follows: 1, nut body；2, screwed hole；3, female thread；4, incline wall.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of steam boiler specialized nut, including nut body 1, described nut body 1 is hex nut, described nut body 1 central authorities offer screwed hole 2, described screwed hole 2 is offered on described nut body 1, described screwed hole 2 medial wall is provided with female thread 3, described female thread 3 encloses wall and is provided with frosted carbon fiber, described female thread 3 protrudes frosted carbon fiber face 8-15mm, it is provided with incline wall 4 outside described nut body 1, polishing on described incline wall 4, after the polishing of described incline wall 4, chromium plating processes.
Enclose on wall it addition, frosted carbon fiber is fixed on described female thread 3 by the way of spraying.
It addition, the upthrow light frosted of described nut body 1 upper and lower end face processes, described nut body 1 upper and lower end face also is provided with frosted carbon fiber.
nullThe operation principle of the present invention be nut body 1 be hex nut，Nut body 1 central authorities offer screwed hole 2，Screwed hole 2 is offered on nut body 1，Screwed hole 2 medial wall is provided with female thread 3，Female thread 3 encloses wall and is provided with frosted carbon fiber，Frosted carbon fiber is fixed on female thread 3 by the way of spraying and encloses on wall，Female thread 3 protrudes frosted carbon fiber face 8-15mm，Incline wall 4 it is provided with outside nut body 1，Polishing on incline wall 4，After incline wall 4 polishing, chromium plating processes，The upthrow light frosted of nut body 1 upper and lower end face processes，Nut body 1 also is provided with frosted carbon fiber on upper and lower end face，Enclose to arrange frosted carbon fiber on wall and polish chromium plating at incline wall 4 at female thread 3 and process，The friction dynamics of nut body 1 outer ring and inner peripheral surface can be increased，Nut is corrosion-resistant、Moistureproof、High temperature resistant and anti-skidding，It is applicable to steam boiler，Not only high temperature steam，And it is the most easy to wear and loosening.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the invention content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in the scope of patent protection of the present invention.
