Abstract

The utility model discloses a mechanical seal structure. The mechanical seal structure comprises a seal base, a positioning screw, a spring, a pushing ring, a moving ring, a stationary ring and O-rings, wherein the positioning screw and the seal base are installed in a matched mode, and one end of the seal base is in a stepped shape; one end of the spring is arranged on a step of the seal base in a sleeved mode, the end, opposite to the seal base, of the pushing ring is also in a stepped mode, and the other end of the spring is arranged on a step of the pushing ring in a sleeved mode; the moving ring is installed behind the pushing ring, and the stationary ring is installed behind the moving ring; the number of the O-rings is two, one O-ring is arranged on the stationary ring in a sleeved mode, and the other O-ring is installed in the moving ring. The spring does not bear torque, the moving ring is driven by the pushing ring to rotate, the pushing ring and the seal are designed to be in a coupled state, and the pushing ring is driven by the seal base, so that the seal bears larger torque, the spring is long in service life, and the mechanical seal structure can be suitable for media large in viscosity.

Description

A kind of mechanical seal device
Technical field
The utility model relates to pump mechanical equipment technical field, is specially a kind of mechanical seal device.
Background technique
Now a lot of double mechanical seals are only suitable for the medium less for viscosity, and spring will bear certain moment of torsion, cause spring life to reduce, in some, the design of rotating ring, throw-out collar and sealing seat is reasonable not, cause the mechanical seal life-span to shorten, directly affected working efficiency.
Model utility content
The purpose of this utility model is to provide a kind of mechanical seal device, unreasonable to solve existing machinery sealing configuration, spring short problem in working life.
In order to address the above problem, the technological scheme that the utility model adopts is:
A kind of mechanical seal device, include sealing seat, positioning screwn, spring, throw-out collar, rotating ring, stationary ring and O type circle, it is characterized in that: described positioning screwn coordinates installation with sealing seat, sealing seat one end is stepped, spring one end is enclosed within on sealing seat ladder, one end that throw-out collar is relative with sealing seat is also stepped, the spring the other end is enclosed within on the ladder of throw-out collar, rotating ring is housed after throw-out collar, described stationary ring is arranged on rotating ring rear, O type circle has two, and one is enclosed within on stationary ring, and another is arranged on rotating ring inside.
Described a kind of mechanical seal device, is characterized in that: on described rotating ring, have groove, throw-out collar is provided with boss, and groove coordinates installation with boss.
Advantage of the present utility model:
Spring of the present utility model does not bear torque, and rotating ring is by throw-out collar driven rotary, and throw-out collar and sealing are designed to coupling state, drives throw-out collar by sealing seat, so sealing can be born larger torque, and spring life is long, applicable to the larger medium of viscosity.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of mechanical seal device, include sealing seat 1, positioning screwn 2, spring 3, throw-out collar 4, rotating ring 5, stationary ring 6 and O type circle 7, described positioning screwn 2 coordinates installation with sealing seat 1, sealing seat 1 one end is stepped, spring 3 one end are enclosed within on sealing seat 1 ladder, one end that throw-out collar 4 is relative with sealing seat 1 is also stepped, spring 3 the other ends are enclosed within on the ladder of throw-out collar 4, rotating ring 5 is housed after throw-out collar 4, and described stationary ring 6 is arranged on rotating ring 5 rears, and O type circle 7 has two, one is enclosed within on stationary ring 6, and another is arranged on rotating ring 5 inside.
On rotating ring 5, have groove, throw-out collar 4 is provided with boss, and groove coordinates installation with boss.

Claims (2)
