Abstract

The utility model discloses a sealing structure of a low pressure compressor air valve cover. The sealing structure of the low pressure compressor air valve cover comprises an air cylinder (300), an air valve cover (100) and a press valve cover (200). The air valve cover (100) comprises a cover body (1). Connecting counter bores (2) are evenly distributed on the edge of the circumference of the cover body (1), and the air valve cover (100) is fixedly connected with the air cylinder (300) through bolts at a position corresponding to the connecting counter bores (2). The cover body (1) is provided with a protruding end (1a) facing the press valve cover (200), the protruding end (1a) is closely abutted on the press valve cover (200), a continuous solid structure is placed on the top of the cover body (1), an annular groove (3) is formed at the protruding end (1a) along the circumference direction, and an O-shaped sealing ring is placed inside the annular groove (3). The sealing structure of the low pressure compressor air valve cover is simple in structure, convenient to install and good in sealing effect due to the fact that the number of leakage points is reduced.

Description

Low pressure compressor air valve cap sealing configuration
Technical field
The utility model relates to a kind of air valve cap sealing configuration of low-pressure gas compressor.
Background technique
In prior art, compressor valve lid sealing configuration comprises cylinder, air valve cap and pressure valve bonnet, and air valve cap and cylinder are bolted to connection, and pressure valve bonnet is arranged in cylinder.At the top of air valve cap, fastening screw is set and holds out against pressure valve bonnet, the fastening screw outer end is with nut braking, sealing.In this structure, screw thread easily causes gas leakage.
Therefore those skilled in the art are devoted to develop a kind of compressor valve lid sealing configuration of good sealing effect.
The model utility content
Because the defects of prior art, technical problem to be solved in the utility model is to provide a kind of compressor valve lid sealing configuration of good sealing effect.
For achieving the above object, the utility model provides a kind of low pressure compressor air valve cap sealing configuration, comprises cylinder, air valve cap and pressure valve bonnet; Described air valve cap comprises lid; The circumferential edges of described lid is evenly equipped with the connection counterbore; Described air valve cap and cylinder are bolted to connection at corresponding described connection counterbore place; Described lid has the protruding terminus towards described pressure valve bonnet, and this protruding terminus is near described pressure valve bonnet; The top of described lid is continuous entity structure; Described protruding terminus along the circumferential direction is provided with annular groove; Be provided with " O " shape seal ring in described annular groove.
Better, the degree of depth of described annular groove is 5.65mm, width is 9.5mm.
Better, the quantity of described connection counterbore is 8.
The beneficial effects of the utility model are: the utility model is simple in structure, and is easy for installation, and owing to having reduced the leak point, so good sealing effect.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the structural representation of air valve cap in the utility model one embodiment.
Fig. 3 is the left view of Fig. 2.
Fig. 4 is the partial enlarged drawing at I place in Fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figures 1 to 4, a kind of low pressure compressor air valve cap sealing configuration comprises cylinder 300, air valve cap 100 and pressure valve bonnet 200.
Air valve cap 100 comprises lid 1, and the circumferential edges of lid 1 is evenly equipped with 8 and connects counterbores 2, and air valve cap 100 and cylinder 300 are fixedly connected with by the bolt (not shown) at corresponding connection counterbore 2 places.
The top of lid 1 is continuous entity structure.Lid 1 has the protruding terminus 1a towards pressure valve bonnet 200, and this protruding terminus 1a is near pressure valve bonnet 200.Protruding terminus 1a along the circumferential direction is provided with annular groove 3, is provided with " O " shape seal ring 4 in annular groove 3.
The degree of depth L1 of annular groove 3 is 5.65mm, and width L2 is 9.5mm.
In the assembly process of air valve cap, because " O " shape seal ring 4 will produce distortion, therefore play the effect that compresses and seal.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all technician in the art comply with design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
