Detailed description of the invention
Fig. 1 is a kind of box-like piston ring structure schematic diagram of hydrogenation stations high pressure hydrogen compressor set proposed by the present invention；
Fig. 2 is A partial enlarged view in Fig. 1.
Specific embodiment
Shown in referring to Figures 1 and 2, a kind of box-like piston ring of hydrogenation stations high pressure hydrogen compressor set proposed by the present invention, packet
Include plug ring 1 and lower plug ring；
Notch is equipped on upper plug ring 1 and lower plug ring；
Upper plug ring 1 is located at notch two sides and forms the first section 11 and the second section 12, and the first section 11 is cut flat with including first
Face and the second tangent plane, the first tangent plane are vertically arranged, and the second tangent plane is obliquely installed, 12 shape of the second section and the first section
11 shape is correspondingly arranged；
Lower plug ring is located at notch two sides and forms third section 21 and the 4th section 22, and third section 21 includes third tangent plane
With the 4th tangent plane, third tangent plane and the 4th tangent plane are obliquely installed, the shape pair of the 4th section 22 and third section 21
It should be arranged.
The present invention is in use, since the first section 11 includes the first tangent plane and the second tangent plane, due to the first tangent plane
Be not generally aligned in the same plane with the second tangent plane, the first section 11 and the second section 12 against when can effectively improve upper plug ring
1 sealing effect.Since third section 21 includes third tangent plane and the 4th tangent plane, since third tangent plane and the 4th is cut flat with
Face is not generally aligned in the same plane, third section 21 and the 4th section 22 against when can effectively improve the sealing effect of lower plug ring
Fruit.The incision site of plug ring 1 and lower plug ring is staggered again when use, can better ensure that sealing effect of the invention.
In present embodiment, third tangent plane and the 4th tangent plane inclined direction are on the contrary, in this way can be effective
Lower plug ring is reduced in use, the issuable shaking in lower plug ring notch place.
