Abstract

The utility model relates to a multifunction combination sealing device which is the improvement of a present sealing device. The opening of a piston ring is provided with an opening baffle sheet and the support sheet of the opening baffle sheet. By using the device, the defects of short service life, easy fail, and poor sealed effect of the present sealing device can be solved.

Description

Multifunction combination sealing device

The utility model relates to seal arrangement, particularly the seal arrangement of piston ring.

Disclose for No. 88206484 by a section clips trapezoidal and a section polygonal piston ring and a garden cylindricality with the most approaching prior art of the utility model such as Chinese patent and to have formed, spring sheet is equipped with in lower end in clips, this structure lost efficacy spring sheet easily and causes clips not have seal action under the effect of high temperature, high pressure.

The purpose of this utility model is: the combined multifunctional seal arrangement that designs a kind of simple in structure, easily manufactured, good sealing effect.

The purpose of this utility model realizes as follows: the opening at piston ring is equipped with opening catch and opening catch supporting spring.

Above-mentioned said opening catch cross section is rectangular thin slice, and opening catch supporting spring processes groove by the piston ring two ends and constitutes.

Above-mentioned said opening catch and supporting spring are made of a part, and its cross section is the opening rectangle, and the front is the I font, shown in Fig. 4,5,6.

Above-mentioned said opening catch is two opening garden ring plates, its opening and gap-clearance of piston rings staggered positions, and its piston ring cross section is a spill.

The utility model has been owing to structurally guaranteed that sealing effect is good, therefore the working life that can improve piston.

Fig. 1 is a kind of embodiment view of the utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the view of facing upward of Fig. 1;

Fig. 4 is an another embodiment view of the present utility model;

Fig. 5 cuts open the back piston panoramic view for the B-B of Fig. 4;

Fig. 6 is that the g of Fig. 5 is to view;

Fig. 7 is that two kinds of materials are in conjunction with the piston structure view of making;

Most preferred embodiment of the present utility model, as shown in Figure 1, 2, opening catch 3 cross sections are rectangular thin slice, opening catch supporting spring 4 is made of the groove that piston ring 2 two ends process, and also can be that rectangular garden ring constitutes by the cross section of band opening, as Fig. 3.1 is piston among the figure.

The opening catch also can be made of a part with supporting spring, and as Fig. 4, its cross section is the opening rectangle, and the front is the I font, shown in Fig. 5,6.

The third embodiment of the present utility model, opening catch are two opening garden ring plates, and the opening staggered positions of its opening and piston ring is installed, and its piston ring cross section is a spill.
