Abstract
The utility model discloses a mechanical sealing device used on steaming chambers, broad washing machines and other devices in dyeing and printing industry. The utility model comprises a spring seat arranged in a bearing seat, the spring seat is provided with an adjustment screw hole, the spring seat is mutually engaged with a moving ring for rotation, and a spring is arranged between the spring seat and the moving ring. The inner chamber of the moving ring is provided with an O-shaped sealing ring, and a sealing surface of a static ring is contacted with a sealing surface of the moving ring. The bearing seat is fixed with a sealing washer and a boxboard via a support seat, and the front fork of the bearing seat can press the static ring on the sealing washer via a rigid pressure ring and a rubber ring. The utility model has the advantages of long service life and convenient sealing part installation and change.
Description
The utility model relates to a kind of mechanical seal device that is used on the equipment such as dyeing decatize case, open soaper.
At dyeing, decatize after the pretreatment of fabric is scouringed and bleaching, printed and dyed, washing are all finished by decatize case and open soaper, the mechanical seal device that uses on this kind equipment comprises: bearing support, one end of bearing support directly and boxboard fix, be provided with spring seat in the bearing support, offer the adjusting screw on the spring seat, the transmission that is meshing with each other of spring seat and rotating ring, spring is arranged between spring seat and the rotating ring, be provided with " O " shape seal ring in the rotating ring inner chamber, the sealing surface of stationary ring contacts with the sealing surface of rotating ring; The osculum end and the stationary ring of a tubaeform rubber seal fix, and its other end is that big opening end and boxboard fix.This kind equipment is generally made casing by stainless steel, and fabric guide roll (axle) becomes horizontal parallel to be placed in the casing, and bearing support places outside the casing, is provided with seal arrangement recited above in the bearing support.During work, because the active force of fabric, fabric guide roll (axle) is in the continuous deformation state always, the running that is fabric guide roll (axle) is a kind of typical decentraction running, and this makes tubaeform rubber seal aging easily, and working life is shorter, and, also more numerous and diverse, difficult during replacing.
The purpose of this utility model is to provide a kind of working life longer, installs, changes mechanical seal device easily.
For achieving the above object, the technical solution adopted in the utility model is: described mechanical seal device comprises: bearing support, be provided with spring seat in the bearing support, offer the adjusting screw on the spring seat, the transmission that is meshing with each other of spring seat and rotating ring, spring is arranged between spring seat and the rotating ring, is provided with " O " shape seal ring in the rotating ring inner chamber, and the sealing surface of stationary ring contacts with the sealing surface of rotating ring; Bearing support fixes by bearing and boxboard, is provided with seal washer between bearing and the boxboard, and the front fork of bearing support is positioned at the bearing inwall, and front fork presses against stationary ring on the seal washer by rigidity pressure ring and rubber ring.
For making things convenient for the position of Regulation spring seat, on bearing, also be provided with the adjusting window.
The utility model has the advantages that: one, working life is longer; Two, replacing is installed conveniently; Three, improved work efficiency.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the structural representation of the utility model mechanical seal device.
As shown in Figure 1, described mechanical seal device comprises: bearing support 1, be provided with spring seat 2 in the bearing support 1, offer on the spring seat 2 and regulate screw 16, the transmission that is meshing with each other of spring seat 2 and rotating ring 13, spring 4 is arranged between spring seat 2 and the rotating ring 13, is provided with " O " shape seal ring 14 in rotating ring 13 inner chambers, and the sealing surface 11 of stationary ring 9 contacts with the sealing surface 12 of rotating ring 13; Bearing support 1 fixes by bearing 5 and boxboard 10, is provided with seal washer 8 between bearing 5 and the boxboard 10, and the front fork 3 of bearing support 1 is positioned at bearing 5 inwalls, and front fork 3 presses against stationary ring 9 on the seal washer 8 by rigidity pressure ring 6 and rubber ring 7.In the present embodiment, be provided with three front forks 3 equably.
For making things convenient for the position of Regulation spring seat 2, on bearing 5, also be provided with and regulate window 15, this adjusting window 15 is arranged in three front forks 3 neutral gear each other.
Because stationary ring 9 is directly pressed against on the seal washer 8, saved the tubaeform rubber seal of original use, so the work of this device is more reliable, and install also very convenient.When reality is used, regulate in the screw 16 and be provided with the position of adjusting screw (not shown) with Regulation spring seat 2, and then the contact pressure between the sealing surface 11 of the sealing surface 12 of adjusting rotating ring 13 and stationary ring 9, make it to keep good sealing property.For easy to adjust, on bearing 5, also be provided with and regulate window 15, this adjusting window 15 can only be established one on bearing 5, also can several be set as required.In the present embodiment, the effect of rigidity pressure ring 6 is that the pressure of front fork 3 is passed to rubber ring 7 and stationary ring 9 equably; Another kind of mode of execution can also be arranged; be about to front fork 3 and make ring; can omit rigidity pressure ring 6 this moment; promptly directly pressure is passed to rubber ring 7 and stationary ring 9 equably by the front fork 3 of ring; but for easy to adjust; must offer simultaneously on the front fork 3 of bearing 5 and ring and regulate window 15, this variation also should belong to protection domain of the present utility model.
Claims (2)
1, a kind of mechanical seal device, comprise: bearing support, be provided with spring seat in the bearing support, offer the adjusting screw on the spring seat, the transmission that is meshing with each other of spring seat and rotating ring, spring is arranged between spring seat and the rotating ring, is provided with " O " shape seal ring in the rotating ring inner chamber, and the sealing surface of stationary ring contacts with the sealing surface of rotating ring; It is characterized in that: bearing support fixes by bearing and boxboard, is provided with seal washer between bearing and the boxboard, and the front fork of bearing support is positioned at the bearing inwall, and front fork presses against stationary ring on the seal washer by rigidity pressure ring and rubber ring.
