Abstract
The utility model relates to a mechanical sealing device, in particular to a mechanical sealing element with rotating force, which is designed aiming at solving the technical problem that the existing like products have poor structure and sealing reliability. The mechanical sealing element comprises a stationary seal ring, a press cover of the stationary seal ring, an O-shaped ring of the stationary seal ring, a rotating seal ring, an O-shaped ring of the rotating seal ring, a rotating seal ring seat, a spring and a spring seat, wherein the spring is arranged between the spring seat and the rotating seal ring seat which is connected with the rotating seal ring; the rotating seal ring is closely matched with the stationary seal ring; the O-shaped ring of the stationary seal ring is positioned between the stationary seal ring and the press cover of the stationary seal ring; and the O-shaped ring of the rotating seal ring is arranged between the rotating seal ring and the rotating seal ring seat as well as a pump shaft. The mechanical sealing element has the key design points that the two ends of the spring are provided with inner hook heads which are respectively matched with slot holes on the rotating seal ring seat and the spring seat. The mechanical sealing element has simpler structure and good sealing reliability, and is suitable for being taken as structural improvement of similar mechanical sealing elements.
Description
Technical field
The utility model relates to mechanical seal device, is a kind of mechanical sealing element that has rotating force.
Background technique
The application area of mechanical sealing element is comparatively extensive, but its purpose plays effective seal exactly, applies in the pump housing as mechanical sealing element, can effectively prevent the leakage of various liquid or air-flow when pump work.
Patent No. ZL200520014137.9 as the Chinese patent literature publication, November 1 2006 notice of authorization day, the model utility name is called " detachable mechanical sealing spare ", and the main points of this model utility are to be with retaining ring in one section end of axle sleeve, and retaining ring is provided with set screw; Another of axle sleeve section end connects spring seat and O shape circle; The stage casing of axle sleeve promptly is provided with location piece, O shape circle, gland nut, stationary ring sealing gasket, stationary ring, rotating ring, O shape circle, rotating seat, spring, driving pin, O shape circle between retaining ring and the spring seat.This detachable mechanical sealing spare is easy with the water pump spindle socket, axially spin stabilization.When indivedual obturators need to change, then only need whole axle sleeve split out water pump spindle, can on worktable, operate, created bigger operating platform and working environment preferably to the maintenance man.
The deficiency that above-mentioned Sealing exists is that structure is comparatively complicated, and sealing reliability is not good enough.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of mechanical sealing element that has rotating force to related domain, makes it solve the structure and the not good enough technical problem of sealing reliability of existing like product.Its objective is and be achieved through the following technical solutions.
A kind of mechanical sealing element that has rotating force, the sealing part comprises stationary ring, seal end plate, stationary ring O type circle, rotating ring, rotating ring O type circle, rotating seat, spring, spring seat, be provided with spring between spring seat and the rotating seat, rotating seat connects rotating ring, rotating ring and stationary ring closely cooperate, be provided with stationary ring O type circle between stationary ring and the seal end plate, be provided with rotating ring O type circle between rotating ring and rotating seat, pump shaft.Its main points are that described both ends of the spring is provided with interior eave tile, interior eave tile cooperates with slotted eye on rotating seat, the spring seat respectively, make spring seat when rotated, spring seat provides rotating force by spring to rotating seat, and the assurance rotating ring closely contacts with stationary ring and plays better sealing effect.
Described spring seat connects pump shaft by fastening screw trip bolt, and pump shaft drives the spring seat rotation.
The utility model structure is comparatively simple, and sealing reliability is good, is suitable as the architecture advances of similar machines Sealing.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model, has omitted seal end plate among the figure.
Above figure number and title 1, stationary ring, 2, stationary ring O type circle, 3, rotating ring, 4, rotating ring O type circle, 5, rotating seat, 6, spring, 7, spring seat, 8, fastening screw trip bolt, 9, pump shaft.
Embodiment
Now in conjunction with the accompanying drawings, structure of the present utility model and principle are further described.
This mechanical sealing element that has rotating force comprises stationary ring 1, seal end plate, stationary ring O type circle 2, rotating ring 3, rotating ring O type circle 4, rotating seat 5, spring 6, spring seat 7, fastening screw trip bolt 8.By fastening screw trip bolt spring seat is connected pump shaft 9, be provided with the spring of eave tile in the band between spring seat and the rotating seat, be provided with rotating ring O type circle between rotating seat and the rotating ring, make to produce sealing between rotating ring and the pump shaft; Be provided with stationary ring O type circle between stationary ring and the seal end plate, make to produce sealing between stationary ring and the pump shaft; Rotating ring closely contacts with stationary ring and produces sealing.Owing to be provided with the spring of eave tile in the band between rotating seat and the spring seat, make spring seat when rotated, produce rotating force between rotating seat and the spring seat, thereby guarantee between rotating ring and the stationary ring contact more tight, seal more reliably, use this kind spring promptly to improve the sealing reliability of this mechanical sealing element.
