Detailed Description

FIG. 1 is a schematic view of the present invention; fig. 2 is a partially enlarged view of a portion a in fig. 1. It should be noted that in the description of the present specification, the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

The utility model provides a pressure disk assembly with combined seal circle, includes pressure disk body 1, sealing washer I4 and sealing washer II 6, is provided with in the sealing washer I4 and prevents the cracked clamp cloth 401 of sealing washer I4, so design can improve the structural strength of sealing washer I4, prolongs the life of sealing washer. Sealing washer I4 is installed in the axial upper portion of pressure disk body 1, sealing washer II 6 is installed in the axial lower part of pressure disk body 1. The sealing washer I4 adopts piece formula pressure disk sealing washer, and sealing washer II 6 adopts "O" type circle formula pressure disk sealing washer, can also adopt other sealing washers that can realize the same function certainly, and this is the technological means that this technical field person can understand, no longer gives unnecessary details here. In this embodiment, the pressure disk is circular structure, and sealing washer I4 and sealing washer II 6 also are radial confined annular structure, and during the installation, pressure disk body 1, sealing washer I4 and sealing washer II 6 are coaxial, and the axial is pressure disk body's axis direction, radially is the diametric (al) of pressure disk, the direction of perpendicular to axis promptly.

In this embodiment, pressure disk body 1 has middle cover 5, middle cover 5 is radial confined annular structure, and the radial outside of pressure disk body 1 is located to middle cover 5 cover with detachable mode, sealing washer I4 is located the 5 axial tops in the middle of, sealing washer II 6 is located the 5 axial belows in the middle of.

In this embodiment, the top of the middle sleeve 5 is provided with a groove 502, the groove 502 is provided at the inner edge of the top surface of the middle sleeve 5, the bottom surface of the sealing ring i 4 is provided with a boss 402 conforming to the groove 502, the boss 402 is provided at the inner edge of the bottom surface of the sealing ring i 4, and the boss 402 radially limits the sealing ring i 4 by being engaged with the groove 502. After the boss 402 is inserted into the groove 502, the seal ring i 4 is radially restrained from moving radially.

In this embodiment, still include gland 3, gland 3 passes through screw 2 and installs in pressure disk body 1's top surface with detachable mode, sealing washer I4 is installed in position department between gland 3 and middle cover 5, and gland 3's diameter is greater than pressure disk body 1, so set up can guarantee that gland 3 and middle cover 5 form the centre gripping spacingly to sealing washer I4 in the axial. Gland 3 and intermediate sleeve 5 are spacing with sealing washer I4 in the axial for sealing washer I4 is unable axial at the axial takes place to remove, and consequently, the axial of sealing washer I4 and radially all by spacing, can't turn over gland 3 and intermediate sleeve 5, and then improved gland component's leakproofness.
