Problems solved by technology

[0003] Several Y-shaped skeletonless sealing rings can be superimposed in one group, and the two sealing brackets in the two groups of Y-shaped skeletonless sealing rings can be installed opposite to each other to seal the hydraulic cylinder. When the hydraulic cylinder works frequently, the environment is harsh or After working for a period of time for a long time, it may cause damage to one or several Y-shaped skeletonless sealing rings in a group. Since the Y-shaped skeletonless sealing ring is installed on the cylinder body of the hydraulic cylinder, if it cannot be removed from the exposed cylinder body To disassemble the damaged Y-shaped skeletonless seal ring, the hydraulic cylinder needs to be completely disassembled. A lot of manpower and material resources are often wasted due to the replacement of a set of Y-shaped skeletonless seal rings, and the replacement cycle is long, which cannot meet the requirements of modern mechanical hydraulic equipment. requirements

Embodiment Construction

[0015] The invention is an easy-to-replace Y-shaped skeleton sealing ring. A T-shaped steel ring is inlaid in the Y-shaped skeleton sealing ring. The internal thread configured in the middle can easily pull out the damaged Y-shaped skeleton sealing ring from the hydraulic cylinder, saving replacement time and avoiding a lot of waste of manpower and material resources.

[0016] The Y-shaped skeleton sealing ring 2 of the present invention is an improved type of the Y-shaped non-skeleton sealing ring 1. One end of the Y-shaped non-skeleton sealing ring 1 has a square flat end and the other end has a semicircular cross-sectional structure. The sealing bracket, the square flat end and the two sealing brackets are all made of non-metallic materials.

[0017] The Y-shaped skeleton sealing ring 2 of the present invention has the same outline and structural dimensions as the Y-shaped non-skeleton sealing ring 1, so the Y-shaped skeleton sealing ring 2 can form a series of products acc...

Abstract

The invention discloses a Y-shaped frame sealing ring convenient to replace. The Y-shaped frame sealing ring (2) is an improvement of a Y-shaped frame-free sealing ring. A sectional structure of one end of the Y-shaped frame-free sealing ring is a square flat end while a sectional structure of the other end of the same is provided with two sealing supports connected by two semi-circles, a T-shaped steel ring (2.1) is arranged inside the square flat end, the diameter of the big end of the T-shaped steel ring is larger than that of the small end of the T-shaped steel ring, an inner thread (2.1.1) is arranged in an inner hole of the small end, an outer end face of the small end is aligned with the square flat end, both the big and the small end are embedded in the square flat end, the big end is arranged reversely to the two sealing supports, and both the big end and the small end are provided with a same symmetrical central line which is in superposition with a central line of the two sealing supports. Via the inner thread, a damaged Y-shaped frame sealing ring can be easily pulled out from a hydraulic oil cylinder, so that replacing time is saved, and large waste of manpower and material resources is avoided.

Description

technical field [0001] The invention belongs to the technical field of sealing rings, and in particular relates to a Y-shaped skeleton sealing ring which is easy to replace. Background technique [0002] figure 1 It is a schematic diagram of the structure of the Y-shaped skeletonless sealing ring. One end of the Y-shaped skeletonless sealing ring 1 has a square flat end in cross section, and the other end has a semicircular cross-sectional structure of two sealing brackets. The square flat end and the two sealing The brackets are all made of non-metallic materials. [0003] Several Y-shaped skeletonless sealing rings can be superimposed in one group, and the two sealing brackets in the two groups of Y-shaped skeletonless sealing rings can be installed opposite to each other to seal the hydraulic cylinder. When the hydraulic cylinder works frequently, the environment is harsh or After working for a period of time for a long time, it may cause damage to one or several Y-shap...
