Abstract
The utility model relates to a high-temperature cylinder sealing assembly, which comprises a cylinder, a piston and a sealing ring assembly, wherein the piston is arranged in the cylinder; a circumferential sealing ring groove is formed in the cylinder or the piston; the sealing ring assembly is arranged in the sealing ring groove, and comprises a first sealing ring and a second sealing ring; the first sealing ring is arranged deep in the sealing ring groove; the second sealing ring is arranged on the opening of the sealing ring groove. According to the high-temperature cylinder sealing assembly disclosed by the utility model, the cylinder and the piston are sealed by combining the first sealing ring and the second sealing ring, so that the air tightness of the cylinder and the wear resistance of the sealing ring assembly are improved, the working efficiency of the cylinder is increased, wear of the sealing ring assembly is reduced, the maintenance frequency of the cylinder is lowered, and a large amount of labor force and materials are saved.
Description
Technical field
The utility model relates to that high temperature cylinder black box, particularly a kind of tightness are good, the high temperature cylinder black box of long service life, belongs to cylinder part technical field.
Background technique
Air cylinder structure widely uses in TOP-TIP, needs to arrange seal ring and ensure the tightness between cylinder and piston in cylinder; The seal ring of cylinder now using, being mostly a sectional shape is circular seal ring, the poor air-tightness of this seal ring causes the inefficiency of cylinder; And some use the seal ring of special construction in order to improve tightness, easily wearing and tearing after long-time use, when especially work under high-temperature condition, seal ring easily hardens, follows the string, and enhance faster wear, cause cylinder to need often to safeguard, change seal ring, wasted a large amount of manpower and materials.
Model utility content
The utility model object is to provide in order to overcome the deficiencies in the prior art that a kind of tightness is good, the high temperature cylinder black box of long service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of high temperature cylinder black box, comprises cylinder, piston and seal ring assembly; Described piston is arranged in cylinder; On described cylinder or piston, be provided with circumferential seal groove; Described seal ring assembly is arranged in seal groove; Described seal ring assembly comprises the first seal ring and the second seal ring; Described the first seal ring is arranged on the depths of seal groove; Described the second seal ring is arranged on the opening of seal groove.
Preferably, the sectional shape of described the first seal ring is circular.
Preferably, the sectional shape of described the second seal ring is rectangle.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The high temperature cylinder black box of the utility model scheme, between cylinder and piston, seal by the form of the first seal ring and the combination of the second seal ring, the tightness of cylinder and the wear resistance of seal ring assembly are improved, improve the working efficiency of cylinder, the wearing and tearing of seal ring assembly are reduced, reduce the frequency of maintenance of cylinder, saved a large amount of manpower and materials.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the sectional view of high temperature cylinder black box described in the utility model;
Accompanying drawing 2 is the partial enlarged drawing of the sectional view of high temperature cylinder black box described in the utility model;
Wherein: 1, cylinder; 2, piston; 3, seal groove; 4, the first seal ring; 5, the second seal ring.
embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1-2, a kind of high temperature cylinder black box described in the utility model, comprises cylinder 1, piston 2 and seal ring assembly; Described piston 2 is arranged in cylinder 1; On described cylinder 1 or piston 2, be provided with circumferential seal groove 3; Described seal ring assembly is arranged in seal groove 3; Described seal ring assembly comprises the first seal ring 4 and the second seal ring 5; Described the first seal ring 4 is arranged on the depths of seal groove 3; Described the second seal ring 5 is arranged on the opening of seal groove 3; The sectional shape of described the first seal ring 4 is circular; The sectional shape of described the second seal ring 5 is rectangle.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The high temperature cylinder black box of the utility model scheme, between cylinder and piston, seal by the form of the first seal ring and the combination of the second seal ring, the tightness of cylinder and the wear resistance of seal ring assembly are improved, improve the working efficiency of cylinder, the wearing and tearing of seal ring assembly are reduced, reduce the frequency of maintenance of cylinder, saved a large amount of manpower and materials.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
