Abstract
The utility model relates to an improved compressor stuffing box which comprises a cylinder body (6) and connecting flanges (1). A group of stuffing boxes (3) are arranged in the cylinder body (6), and each stuffing box (3) is internally provided with one seal ring (2). The improved compressor stuffing box is characterized in that two ends of the stuffing boxes (3) matched with the flanges are respectively provided with cavities for placing the seal rings (2), two cavities are communicated through an axial through hole, and a baffle (5) is arranged at one ends of the stuffing boxes (3) corresponding to one side of the cylinder body (6) and is positioned between two adjacent stuffing boxes (3). The improved compressor stuffing box has the advantages that an improved structural sealing face is easy to process, sealing stability can be guaranteed easily, and sealing reliability is improved.
Description
Technical field
The utility model relates to the seal arrangement of compressor industry, especially a kind of improved compressor packing box.
Background technique
Filler is the main seal element between compresser cylinder and piston rod, it can stop gas to be revealed from cylinder chamber's one lateral axis side, the stuffing box that band fills nitrogen, air extracting seal structure was Split type structure originally, the seal ring that is contained in cylinder side is sealing surface with the internal surface that coordinates of stuffing box, therefore the roughness of the internal surface of stuffing box is had relatively high expectations, need to grind and just can reach requirement, because the area of stuffing box internal surface (endoporus) is less, can't guarantee roughness by grinding in reality processing, therefore cause the increase of air leakage.
The model utility content
The purpose of this utility model is exactly for the sealing that overcomes existing compresser cylinder seals with the internal surface that coordinates of stuffing box by seal ring, and the stuffing box internal surface should not process the defective that satisfies seal request, and a kind of improved compressor packing box is provided.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of improved compressor packing box, comprise cylinder body and adpting flange, be provided with one group of stuffing box in cylinder body, be provided with a seal ring in each stuffing box, it is characterized in that: the two ends of the described stuffing box that coordinates with flange are respectively equipped with the cavity of placing seal ring, two cavitys connect by axial hole, and stuffing box one end corresponding in cylinder body one side is provided with baffle plate, and baffle plate is located between two adjacent stuffing boxes.
The structure of stuffing box is made integrated type, increases a baffle plate; After architecture advances, the sealing surface of stuffing box changes the exterior edge face into by original inner hole surface, directly grinds the exterior edge face and gets final product, and easily guarantees to grind needed roughness, thereby has well guaranteed sealing effect
On the basis of above-mentioned main technical schemes, can increase following further perfect technological scheme:
Described stuffing box is provided with bleed-off passage.
The beneficial effects of the utility model are that the sealing structure face after improving is easy to processing, thus can easily guarantee to seal stable, the reliability that has improved sealing is high.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Description of drawings:
Fig. 1 is plan view of the present utility model.
Embodiment
as shown in Figure 1, a kind of improved compressor packing box of the utility model, comprise cylinder body 6, cylinder body 6 is provided with for the cavity of placing stuffing box 3, opening end at cylinder body 6 is provided with adpting flange 1, be provided with one group of stuffing box 3 in cylinder body 6, be provided with a seal ring 2 in each stuffing box 3, the two ends of the described stuffing box that coordinates with flange 3 are respectively equipped with the cavity of placing seal ring, two cavitys connect by axial hole, stuffing box 3 one ends corresponding in cylinder body 6 one sides are provided with baffle plate 5, baffle plate 5 is provided with axial hole, baffle plate 5 is located at 3 of two adjacent stuffing boxes, described stuffing box 3 is provided with bleed-off passage, be used for extracting out a small amount of leakage gas.
The structure of stuffing box 3 is made integrated type, increases a baffle plate 5, and baffle plate 5 is sealing surface 4 with the fitting surface of stuffing box 3; After architecture advances, the sealing surface of stuffing box 3 changes the exterior edge face into by original inner headed face, directly grinds the exterior edge face of stuffing box 3 and the exterior edge face of baffle plate 5 and gets final product, and easily guarantees to grind needed roughness, thereby has well guaranteed sealing effect.
Claims (2)
1. improved compressor packing box, comprise cylinder body (6) and adpting flange (1), be provided with one group of stuffing box (3) in cylinder body (6), be provided with a seal ring (2) in each stuffing box (3), it is characterized in that: the two ends of the described stuffing box that coordinates with flange (3) are respectively equipped with the cavity of placing seal ring (2), two cavitys connect by axial hole, stuffing box (3) one ends corresponding in cylinder body (6) one sides are provided with baffle plate (5), and baffle plate (5) is located between adjacent two stuffing boxes (3).
