Abstract

The utility model relates to a packing sealing ring of a gas compressor, comprising a ring body which is formed by three sections of arc-shaped ring blocks with the same shapes and structures; the outer surface of the ring body is provided with a groove which is internally provided with a ring-shaped spring. The end surfaces of the two sides of the arc-shaped ring blocks are planes passing throughthe central axis of the ring body or inclined planes parallel to the central axis of the ring body or composite planes; the composite planes are formed by two planes in a cross manner; and the two planes are respectively parallel to the central axis of the ring body. The packing sealing ring of the gas compressor has wide application range, good sealing effect and convenient installation and use.

Description

Gas compressor packing seal ring

Technical field

The utility model relates to a kind of gas compressor packing seal ring.

Background technique

On the packing seal ring of the middle use of gas compressor requires basis in good sealing property, also to have elasticity preferably.Common seal ring elasticity is little, can only be fixedly mounted on usually on sealed, can not adapt to the requirement of different-diameter Sealing, and sealing effect is undesirable.

Summary of the invention

The purpose of this utility model provides a kind of gas compressor packing seal ring of applied widely, good sealing effect.

For achieving the above object, the utility model is by the following technical solutions:

Gas compressor packing seal ring described in the utility model is characterized in that: comprise by three sections shapes, structure just as the ring body that constitutes of arc ring piece, the outer surface belt of ring body is fluted, and the spring of ring-type is installed in the groove.

Described arc ring piece end faces of both sides is the plane by the ring body medial axis.

Described arc ring piece end faces of both sides is the inclined-plane parallel with the ring body medial axis.

Described arc ring piece end faces of both sides is a composite surface, and this composite surface is made of two crossing on the same levels, and described two planes are all parallel with the ring body medial axis.

After adopting technique scheme, applied widely, the good sealing effect of this gas compressor packing seal ring, easy to install.

Description of drawings

Fig. 1 is a kind of embodiment's of the utility model a structural representation;

Fig. 2 is Fig. 1 embodiment's a longitudinal sectional view;

Fig. 3 is the another kind of embodiment's of the utility model a structural representation;

Fig. 4 is another embodiment's of the utility model a structural representation.

Embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

As shown in drawings, gas compressor packing seal ring described in the utility model, ring body 1 by three sections shapes, structure just as arc ring piece constitute, fluted 2 at the outer surface belt of ring body 1, the spring of ring-type is installed in the groove 2, spring does not all draw in each accompanying drawing.

Described arc ring piece end faces of both sides also is and the surface of contact of contiguous another arc ring piece, and the shape of this surface of contact can have multiple, and this surface of contact can be the plane 21 of passing through ring body 1 medial axis as shown in Figure 1; Also can be the inclined-plane 22 parallel with ring body 1 medial axis as shown in Figure 3, inclined-plane 22 be by ring body 1 medial axis; Can also be composite surface 23 as shown in Figure 4, this composite surface 23 be made of two crossing on the same levels, and described two planes are all parallel with ring body 1 medial axis.

Each arc ring piece joins end to end and constitutes ring body 1 circlewise, and spring housing is fixed each arc ring piece in the groove 2 of ring body 1 outside.Like this, this gas compressor packing seal ring can be sleeved at an easy rate to be needed on the axle of the sealing part, easy to install, applied widely, good sealing effect.
