Abstract
The utility model relates to an intermediate body washer. The intermediate body washer comprises a washer body, wherein a high seal groove and a low seal groove are formed in the circumferential surface of the washer body; the high seal groove and the low seal groove are annularly arranged and respectively formed in a high position and a low position; the high seal groove is in transition connection to the low seal groove through a bevel edge. The intermediate body washer has the benefits as follows: the part, of the original intermediate body, matched with a piston assembly is made into a single washer; in the aspect of matching, air leakage is unlikely to occur through the matching between the intermediate body and the piston assembly; compared with the original method, the method adopted by the intermediate body washer has the advantages that the intermediate body washer is convenient to mount and high in sealing performance, and separate processing operation is convenient.
Description
Technical field
The utility model relates to packing ring, particularly body packing ring in one.
Background technique
Middle body packing ring on body with piston assembly mating part, generally adopt multiple packing rings, middle body is coordinated with piston assembly easily and leaks gas, be not easy to installation, sealing is poor, machining operation inconvenience.
Model utility content
The utility model has solved above-mentioned deficiency of the prior art, and body packing ring in one is provided.
The utility model solves the technological scheme that its technical problem adopts: this middle body packing ring, comprise washer body, the circumferential surface of washer body is provided with a high-order seal groove and a low-level seal groove, and high-order seal groove and low-level seal groove are height annular and arrange and cross connection by hypotenuse limit.
The beneficial effects of the utility model are: will on original middle body, make single-piece packing ring with piston assembly mating part, and on coordinating, middle body be coordinated with piston assembly and be not easy gas leakage, and with former method ratio, be convenient to install, and good airproof performance, separate machined is easy to operate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Description of reference numerals: washer body 1, high-order seal groove 1-1, low-level seal groove 1-2, hypotenuse 1-3.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in the figure, this middle body packing ring, comprises washer body 1, and the circumferential surface of washer body 1 is provided with a high-order seal groove 1-1 and a low-level seal groove 1-2, and high-order seal groove 1-1 and low-level seal groove 1-2 are height and arrange and cross connection by hypotenuse 1-3 limit.To on original middle body, make single-piece packing ring with piston assembly mating part, and on coordinating, middle body be coordinated with piston assembly and be not easy gas leakage, and with former method ratio, be convenient to install, good airproof performance, separate machined is easy to operate.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
