Description
Technical field
The utility model relates to a kind of belt carcass O shape and encloses whole split type mechanical seal device, mainly is applicable in the rotating machinery that adopts integral seal.
Background technique
Split type mechanical seal commonly used uses seal ring that two kinds of forms are arranged: a kind of is that whole O shape is enclosed direct angle and cut off, and characteristics are that the seal ring profile is not had binding character, satisfy seal request substantially; Another kind is a spherical joint O shape circle, and characteristics are that the seal ring profile is had binding character, satisfy seal request, and joint is difficult for installing and damaging easily.The elastic tissue of split type mechanical seal commonly used is whole with end cover all, the user can't be according to self use condition adjusting axle to reduced size and there is not good centering function, and the rotating machinery that adopts integral seal is in place under repair with very inconvenient when changing seal arrangement.
Summary of the invention
At the deficiency of existing split type mechanical seal, the utility model provides a kind of belt carcass O shape to enclose whole split type mechanical seal device.
To achieve these goals, the measure taked of the utility model is:
A kind of belt carcass O shape is enclosed whole split type mechanical seal device, comprise rotating seal component and standstill seal assembly, the standstill seal assembly is by end cap and the stationary ring that is attached thereto, and elastic element is formed, the end cap that is provided with pin by screw on main shaft, be disposed with end bracket enclosed pad and belt carcass O shape circle between end cap and the stationary ring, the elastic element that links together with end cap is fixed on the main shaft, described rotating seal component comprises drive sleeve and the rotating ring that links together by pin, between the drive sleeve on the main shaft and main shaft and rotating ring, respectively be provided with a belt carcass O shape circle by screw, belt carcass O shape circle links to each other with drive sleeve sealing gasket on being connected drive sleeve, and rotating ring and stationary ring link together;
Described elastic element comprises spring and spring seat, and Placement is an external-mounted structure;
Described spring seat is provided with the centring means limiting stopper;
Described belt carcass O shape circle is connected with the rubber pipe of extension spring or coil component spring steel wire for inner socket joint;
Described end bracket enclosed pad is the L type, and the one end links to each other with pad, and the other end is connected with belt carcass O shape circle.
The beneficial effects of the utility model: belt carcass O shape is enclosed whole split type mechanical seal device and is used belt carcass seal ring and extension spring or the combination of coil component spring steel wire socket joint can retrain the seal ring profile also to satisfy seal request and install and be not easy to damage installation and easy to maintenance simply again; Using the external mounted elastic element is that end cover and spring seat are separated, thereby the user can satisfy seal request to reduced size according to the suitable adjusting axle of self use condition, the subsidiary centring means of spring seat can be got preferably and play positioning action, make the more accurate of mechanical seal installation, function is more reliable.

Embodiment
A kind of belt carcass O shape is enclosed whole split type mechanical seal device, comprise rotating seal component and standstill seal assembly, the standstill seal assembly is by end cap 1 and the stationary ring 10 that is attached thereto, and elastic element is formed, the end cap 1 that is provided with pin 2 is fixed on the main shaft by screw 3, be disposed with end bracket enclosed pad 4 and belt carcass O shape circle 9 between end cap 1 and the stationary ring 10, the elastic element that links together with end cap 1 is fixed on the main shaft, described rotating seal component comprises drive sleeve 5 and the rotating ring 8 that links together by pin 2, be fixed on by screw 3 and respectively be provided with a belt carcass O shape circle 9 between drive sleeve 5 on the main shaft and main shaft and the rotating ring 8, belt carcass O shape circle 9 links to each other with drive sleeve sealing gasket 11 on being connected drive sleeve 5, and rotating ring 8 and stationary ring 10 link together; Described elastic element comprises spring 7 and spring seat 12, and Placement is an external-mounted structure; Described spring seat 12 is provided with centring means limiting stopper 6; Described belt carcass O shape circle 9 is connected with the rubber pipe of extension spring or coil component spring steel wire for inner socket joint; Described end bracket enclosed pad 4 is the L type, and the one end links to each other with pad 13, and the other end is connected with belt carcass O shape circle 9.Belt carcass O shape circle 9 stop media between machine spindle and the seal arrangement, reveal between drive sleeve 5 and the rotating ring 8 and stationary ring 10 and end cover 1 between reveal, stationary ring 10 and rotating ring 8 relative rotations, thus sealing surface fits tightly the leakage of prevention medium; The external mounted elastic element is supported spring 7 by spring seat 12, and spring 7 is compressed the back and applies axial thrust to stationary ring 10 simultaneously, guarantees the sealing surface applying.
The beneficial effects of the utility model: belt carcass O shape is enclosed whole Split type mechanical seal device and is used belt carcass sealing ring and extension spring or coil component spring bearing steel wires insert group to close can to retrain the sealing ring profile also can satisfy seal request and install to be not easy simply again to damage installation and easy to maintenance; Using the fitted outside elastic element is that end cover and spring base are separated, thereby the user can satisfy seal request to reduced size according to the suitable regulating shaft of self operating position, the subsidiary centring means of spring base can play positioning action preferably, make the more accurate of mechanical seal installation, function is more reliable.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in this area.
