Abstract
The utility model relates to a piston rod is with combination sealing member, it mainly by: cylinder, recess, sealing member, piston, rectangle retaining ring, sealing ring, elastomer constitute. The piston is provided with a groove, the sealing element is arranged in the groove, two symmetrical rectangular check rings are arranged on two sides of the sealing element, a sealing ring is arranged between the two rectangular check rings, an elastic body is arranged between the inner side of the sealing ring and the inner sides of the two rectangular check rings, and the cylinder barrel and the piston are sealed through the sealing element. This product simple structure, reasonable in design, the sealing ring cross section of this sealing member adopts the chevron shape, and the during operation can bear the high pressure, and wear resistance is good, is equipped with the elastomer in the sealing member, and accessible elastomer has an elastic compensation to inside to outside after the sealed face wearing and tearing of sealing ring, has prolonged the life of sealing member, has reduced manufacturing cost.
Description
Technical Field
The utility model relates to a piston rod is with combination sealing member.
Background
At present, the sealing ring of an integrated structure is adopted between the retainer ring and the retainer ring of the existing piston sealing element, the corrosion resistance and the wear resistance are poor during the working process, an elastic body is not arranged in the sealing element, the elastic compensation can not be realized from the elastic body to the inside and the outside after the sealing surface of the sealing ring is worn, the sealing element is troublesome to replace after being worn, the time and the labor are wasted, and the production cost is increased.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned shortcoming, provide a piston rod is with combination sealing member, it has mainly solved current piston seal spare, adopts the sealing ring of a body structure between retaining ring and the retaining ring, and the during operation is corrosion-resistant, wear resistance is poor, does not have the elastomer in the sealing member, can not have an elastic compensation scheduling problem to inside outside through the elastomer after the sealed face wearing and tearing of sealing ring. The utility model aims at realizing like this, the piston rod is by with the combined seal spare: cylinder, recess, sealing member, piston, rectangle retaining ring, sealing ring, elastomer constitute. The piston is provided with a groove, the sealing element is arranged in the groove, two symmetrical rectangular check rings are arranged on two sides of the sealing element, the sealing ring is arranged between the two rectangular check rings, the cross section of the sealing ring is in a shape like a Chinese character 'shan', an elastic body is arranged between the inner side of the sealing ring and the inner sides of the two rectangular check rings, and the cylinder barrel and the piston are sealed through the sealing element. This product simple structure, reasonable in design, the sealing ring cross section of this sealing member adopts the chevron shape, and the during operation can bear the high pressure, and wear resistance is good, is equipped with the elastomer in the sealing member, and accessible elastomer has an elastic compensation to inside to outside after the sealed face wearing and tearing of sealing ring, has prolonged the life of sealing member, has reduced manufacturing cost.

1-cylinder 2-recess 3-sealing member 4-piston 5-rectangular retainer ring 6-sealing ring 7-elastomer.
Detailed Description
The best embodiment of the present invention will be described in detail below with reference to the accompanying drawings, wherein the combined sealing member for the piston rod is composed of: the cylinder barrel 1, the groove 2, the sealing piece 3, the piston 4, the rectangular retainer ring 5, the sealing ring 6 and the elastic body 7. The piston 4 is provided with a groove 2, the sealing element 3 is arranged in the groove 2, two symmetrical rectangular check rings 5 are arranged on two sides of the sealing element 3, a sealing ring 6 is arranged between the two rectangular check rings 5, the cross section of the sealing ring 6 is in a shape of Chinese character 'shan', an elastic body 7 is arranged between the inner side of the sealing ring 6 and the inner sides of the two rectangular check rings 5, and the cylinder barrel 1 and the piston 4 are sealed through the sealing element 3.
During operation, sealing member 3 is installed in recess 2, and the both sides of sealing member 3 are equipped with two symmetrical rectangle retaining rings 5, can effectually prevent that sealing ring 6 from extruding, and accessible elastomer 7 has an elastic compensation to inside to outside after the sealed face wearing and tearing of sealing ring 6.
