Abstract
The utility model relates to a sealing device for a joint and belongs to the technical field of drilling rig equipment. The sealing device for the joint comprises a main shaft inside a box body, the front end of the main shaft is connected with a rotating sleeve through a flat key, a seal cover is arranged on the outer ring of the rotating sleeve, and one end of the seal cover is connected with the box body through a second bolt. A V-shaped clip textile seal ring is arranged between the seal cover and the rotating sleeve, the other end of the seal cover is connected with a sealing gland through a first bolt, and the sealing gland presses the V-shaped clip textile seal ring into the seal cover. The external end of the sealing gland is connected with an inlet joint, and the inlet joint is connected with a bend pipe. The sealing device for the joint is simple, compact and reasonable in structure, quick-wear parts are easy to replace, manufacturing cost and maintenance cost are low, and the sealing requirement of high-pressure air can be met.
Description
Technical field
The utility model relates to a kind of joint sealing device, belongs to the drilling equipment technical field.
Background technology
In the drilling operation in the open air, operating mode is more abominable, and its part and structure all should be design principles with simple, practicality; Require to install and convenient disassembly, and for ease of maintenaince, be fit to open-air area and use.Seal is a consumable accessory, and structure commonly used all has the limitation that sealing performance is unreliable and replacing is inconvenient, so be not suitable for the sealing of pressure-air.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of joint sealing device that transmits pressure-air that is applicable to is provided, and has guaranteed the sealing fully of contact surface between each part.
The technical scheme that provides according to the utility model, the joint sealing device comprises the main shaft that is positioned at casing, is provided with bearing between casing and the main shaft, it is characterized in that: described front-end of spindle connects pivoted housing by flat key, the pivoted housing outer ring is provided with seal cover, and seal cover one end is by the second bolt connect box.Be provided with V-type folder fabric sealing ring between described seal cover and the pivoted housing, the seal cover other end connects gland by first bolt, and gland presss from both sides the fabric sealing ring with V-type and is pressed in the seal cover.Described gland outer end connects inlet suction port, bridge piece on the inlet suction port.
Further, be provided with bearing gland between casing and the seal cover, spacing by bearing gland to bearing.
Further, be provided with the 2nd O RunddichtringO between main shaft and the pivoted housing.
Further, main shaft one end connects circlip, and circlip is near pivoted housing.
Further, be provided with an O RunddichtringO between gland and the seal cover.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable; Consumable accessory is changed convenient; Manufacturing and maintenance cost are low; Can satisfy the seal request of pressure-air.
Description of drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-bend pipe, 2-inlet suction port, 3-gland, 4-pivoted housing, 5-V-type folder fabric sealing ring, 6-seal cover, 7-bearing gland, 8-bearing, 9-casing, 10-main shaft, 11-first bolt, 12-circlip, 13-the one O RunddichtringO, 14-the 2nd O RunddichtringO, 15-second bolt.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, the utility model mainly comprises the main shaft 10 that is positioned at casing 9, is provided with bearing 8 between casing 9 and the main shaft 10.Described main shaft 10 front ends connect pivoted housing 4 by flat key, and pivoted housing 4 outer rings are provided with seal cover 6, and seal cover 6 one ends are by second bolt, 15 connect boxes 9.Be provided with V-type folder fabric sealing ring 5 between described seal cover 6 and the pivoted housing 4, seal cover 6 other ends connect gland 3 by first bolt 11, and gland 3 presss from both sides fabric sealing ring 5 with V-type and is pressed in the seal cover 6.Described gland 3 outer ends connect inlet suction port 2, and bridge piece 1 on the inlet suction port 2.
Be provided with bearing gland 7 between described casing 9 and the seal cover 6, spacing by 7 pairs of bearings 8 of bearing gland.
Be provided with the 2nd O RunddichtringO 14 between described main shaft 10 and the pivoted housing 4.
Described main shaft 10 1 ends connect circlip 12, and circlip 12 is undertaken spacing near pivoted housing 4 by 12 pairs of pivoted housings of circlip 4.
Be provided with an O RunddichtringO 13 between described gland 3 and the seal cover 6.
Operating principle of the present utility model is: compressed air enters inlet suction port 2 through high-pressure rubber pipe, enters at last in the main shaft 10.Main shaft 10 rotates simultaneously with pivoted housing 4, and V-type folder fabric sealing ring 5 does not rotate, and stops compressed air to leak simultaneously, in when, in the use wearing and tearing taking place, only need dismounting down V-type folder fabric sealing ring 5 change, can continue use.
The utility model is simple in structure, compact, reasonable; Consumable accessory is changed convenient; Manufacturing and maintenance cost are low; Can satisfy the seal request of pressure-air.
