Description
Technical Field
The utility model relates to a compressor technical field, the utility model provides an explosion-proof gland structure for reciprocating compressor.
Background
The reciprocating compressor is a positive displacement compressor which changes the internal volume of a compression cavity by one or more pistons making reciprocating motion, and mainly comprises a motion mechanism, a working mechanism and a machine body, wherein the working mechanism comprises a cylinder, a piston, an air valve and the like, the air valve is a key part of the air valve, a cover plate and a sealing ring are required to be arranged at the air valve for fixing and sealing, the existing cover plate mode adopts a structure of a flat cover and a compression screw, as shown in figure 1, the flat cover is fixed on a cylinder body through a bolt, a small-diameter compression screw is further installed on the flat cover to abut against the air valve, the fixing mode adopts point contact, the air valve is easily damaged when the adjusting force is excessively applied, the screw is easy to loosen during long-term operation, and the economy of the installation screw is not good.
Disclosure of Invention
In order to solve the current mode of screw fixation and cause the damage to the pneumatic valve easily, compress tightly the not good problem of effect for a long time, the utility model provides an explosion-proof gland structure for reciprocating compressor, it can conveniently realize the reliable fixed to the pneumatic valve, can not cause the damage to the pneumatic valve, and economic nature is good.
The technical scheme is as follows: the utility model provides an explosion-proof gland structure for reciprocating compressor, its includes the cylinder block, install the apron through the bolt on the cylinder block, its characterized in that, pneumatic valve installation department is provided with the step hole, be provided with the sealing washer on the step face in step hole, sealing washer outer lane part support in step face, inner circle part support in the pneumatic valve, be provided with the bulge loop in the middle of the apron inboard just the bulge loop is pushed down the sealing washer, the lower terminal surface of bulge loop has seted up the round recess, the groove position with the pneumatic valve with the boundary of step face corresponds.
It is further characterized in that the radial cross-section of the groove is triangular;
the middle of the cover plate is outward arched, and a cavity is reserved between the inner side of the middle of the cover plate and the air valve.
Adopt the utility model discloses afterwards, the bulge loop on the apron passes through the sealing washer and pushes down the pneumatic valve, changes into the face contact from original point contact, can not cause the damage to the pneumatic valve, and area of contact is bigger moreover, and better realization pneumatic valve compresses tightly fixedly, and economic nature is good.
Drawings
FIG. 1 is a schematic diagram of a prior art structure;
FIG. 2 is a schematic view of the present invention;
FIG. 3 is a schematic view of the convex ring contacting the sealing ring.
Detailed Description
Referring to fig. 2 and 3, the explosion-proof gland structure for the reciprocating compressor comprises a cylinder body 1, wherein a cover plate 3 is installed on the cylinder body 1 through a bolt 2, a step hole is formed in the installation position of an air valve 4, a sealing ring 6 is arranged on a step surface 5 of the step hole, the outer ring part of the sealing ring 6 is supported on the step surface 5, the inner ring part of the sealing ring 6 is supported on the air valve 4, the air valve 4 is slightly higher than the step surface 5 and is about 0.03-0.05mm, a convex ring 7 is arranged in the middle of the inner side of the cover plate 3, the convex ring 7 presses the sealing ring 6, a circle of groove 8 is formed in the lower end surface of the convex ring 7, the radial cross section of the groove 8 is triangular, the position of the groove 8 corresponds to the boundary between the air valve 4 and the step surface 5, the pressing surface of the sealing ring 6 can be divided into two parts, and the inner side can better press the air valve 4.
Be outside arch in the middle of the apron 3, leave cavity 9 between inboard and the pneumatic valve 4 in the middle of the apron 3, still played explosion-proof effect, make the utility model discloses a product possesses better economic nature.
Claims (3)
