Abstract
The utility model relates to a fully-sealed turning connection device which is installed on crane pipes. A casing is composed of a big press cover and an outer thread disc, and a box disc type ball friction rotating mechanism is arranged in the casing, and is sealed by a rubber ring. The utility model solves the problem the crane pipe steering devices have the defects of large size, easy corrosion, inconvenient maintenance, short service life, etc. The utility model can be used on pipelines for conveying gas and liquid, and is particularly suitable for the use of crane pipe pipelines of various calibres for receiving and sending oil in oil depots.
Description
The utility model is a kind of hermetically sealed the steering gear that is installed on the oil filling riser.
In oil plant storehouse or gas station, there is a kind of pipeline when stretching, to be stepped shaft, and collapsible, be commonly referred to " oil filling riser ".Flexible, the rotation of oil filling riser are to realize by the commutator that is connected on the pipeline.Relatively Chang Yong a kind of commutator structure is such: between inside and outside two covers twice ring shaped slot is arranged, ball is encapsulated in the groove, realize the connection and the rotation of two covers.This commutator is rotated flexibly, and is oil-proof.Shortcoming is, the first, and volume is big, can not use on small-bore pipeline; The second, inconvenient maintenance; The 3rd, the blow-by of ball attachment portion, the corrosion of easily intaking; The 4th, rubber ring is fragile.
The purpose of this utility model provides a kind of novel fully-sealed loose joint that turns to, and not only turns to flexibly, and is oil-proof, and overcomes the easy-to-rust that existing product exists, inconvenient maintenance, and volume is big, problems such as rubber seal rapid wear.
The purpose of this utility model is achieved through the following technical solutions.
The hermetically sealed loose joint outward appearance that turns to is the garden cylindricality, is adopted to be threaded by tapped big gland and an outside thread dish to constitute shell.Internal thread ball box is connected and is with the cross section respectively two circular grooves of ball dish formation of convex with outside thread ball box, the dress ball has constituted rotating mechanism in the circular groove.A rubber seal, leakage proof are arranged between outside thread ball box, outside thread dish and the ball dish.Non-leakage for adjusting the rubber seal assurance, between outside thread ball box and outside thread dish, add asbestos packing.Big gland is pressed in water tight packing between the slit of internal thread ball box and the formation of ball dish.When turning to loose joint to be connected with pipeline, one terminates on the ball dish, and the other end is connected on the outside thread dish.
The utility model has the advantages that: hermetically sealed; Volume is little, is adapted to the pipeline of various bores; Easy to maintenance; Long service life.
Be illustrated below in conjunction with accompanying drawing.
The loose joint that turns to shown in the figure one is connected to form shell by a big gland 2 and an outside thread dish 11 that has internal thread.Internal thread ball box 5, outside thread ball box 6 form circular groove 8 with ball dish 7 respectively, in the ring shaped slot 8 ball are housed, and this part is the utility model rotating mechanism.Be rubber seal 10 between outside thread ball box 6, outside thread dish 11 and the ball dish 7, asbestos packing 9, water tight packing 3, big gland plate hole 1, ball box plate hole 4, pipeline 12 is connected with ball dish 7, outside thread dish 11 at two ends respectively.
Claims (3)
1, a kind ofly is installed in hermetically sealed on the oil filling riser and turns to loose joint, feature of the present utility model is: big gland 2 and outside thread dish 11 with internal thread connect and compose shell of the present utility model, internal thread ball box 5, outside thread ball box 6 form ring shaped slot 8 respectively with ball dish 7, ball is contained in the ring shaped slot 8, has sealing rubber ring 10, ball dish 7, outside thread dish 11 to be connected with the pipeline 12 at two ends respectively between outside thread ball box 6, outside thread dish 11 and the ball dish 7.
2, the hermetically sealed loose joint that turns to according to claim 1 is characterized in that between big gland 2, internal thread ball box 5 and the ball dish 7 water tight packing 3 being arranged.
3, the hermetically sealed loose joint that turns to according to claim 1 is characterized in that between outside thread ball box 6 and the outside thread dish 11 one deck asbestos packing 9 being arranged.
