Have groove from the pressing plate edge to the center on pressing plate, be used for oil pipe end and snap in pressing plate.
Described clamping cap is provided be used to the handle that rotatably compresses cap.
Described chuck body is fixed by screws in the outlet of cleaning equipment high-pressure cleaning liquid, and bottom hole docks with the high-pressure cleaning liquid outlet.
Advantage of the present invention is: guarantee the requirement of inner cavity of high-pressure oil pipe cleannes, and simple in structure, easy to use, to increase work efficiency, mould handling is simple and convenient, and is safe and reliable, and cost is low.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the spool schematic diagram.
Fig. 3 is the top view of pressing plate.
Fig. 4 is use state diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As Fig. 1, shown in 2, described inner cavity cleaning clamp for high-pressure oil pipe comprises chuck body 6, and spool 7 is positioned at described chuck body 6 centers, and spool 7 upper ends covers have joint 8, and joint 8 bottoms are threaded with chuck body 6.Overlapping in 7 one weeks of waist of spool has sealing ring 9, and described sealing ring 9 is arranged in the crack of joint 8 bottoms and chuck body.Described spool 7 bottoms and chuck body 6 leave the gap, are provided with base plate 11 below spool 7, fix the first Compress Spring 10(1.5*8*15GB2089 on base plate 11) an end, the lower end that first Compress Spring 10 other ends withstand described spool 7.Described base plate 11 is fixing with body 6 by hexagonal chapiter screw in M6 12.Spool has cavity 7-1 in 7 tops, and cavity 7-1 is at spool 7 top end openings, and spool 7 sidewalls are provided with valve core through hole 7-2, is communicated with the cavity 7-1 that spool 7 is outer and spool 7 is interior.When the first Compress Spring 10 during with spool 7 jack-up, valve core through hole 7-2 is by described sealing ring 9 sealings, and simultaneously, spool 7 bottoms are by base plate 11 and chuck body 6 sealings, and therefore the space between whole spool 7 and chuck body 6 seals.
Be provided with pressing plate 3 on chuck body 6, two guide pillars 4 be installed below pressing plate 3, chuck body 6 are inserted in guide pillar 4 lower ends, and on the guide pillar 4 between chuck body 6 and pressing plate 3, cover has the second Compress Spring 5(1.5*12*30GB2089).Pressing plate 3 upper ends are pushed down by clamping cap 2, and the bottom of clamping cap 2 is connected with the chuck body outer periphery threads.Clamping cap 2 is provided with the handle 1 for this clamping cap 2 of rotation.
Chuck body 6 is fixed in cleaning equipment high-pressure cleaning liquid outlet by hexagonal chapiter screw 13 in M10, and the bottom hole 11-1 at base plate 11 centers exports with high-pressure cleaning liquid and docks, and can effectively prevent oil leakage phenomenon.Pressing plate 3 is connected with chuck body 6 by guide pillar 4, the second Compress Spring 5, assurance pressing plate 3 can with chuck body 6 maintenance levels.
Spool 7 sidewalls can be provided with a circle valve core through hole 7-2(and be illustrated as 2), sealing ring 9 be O type rubber seal, during by jack-up, the sealed circle 9 of described valve core through hole 7-2 seals when spool 7.Joint 8 is threaded with chuck body 6, adds that sealing ring 9 can effectively prevent oil leakage phenomenon.
Handle 1 can make clamping cap 2 rotarily drive pressing plate 3 on chuck body 6 and move up and down, thereby plays compression, unclamp the purpose that is cleaned oil pipe.As shown in Figure 3, have groove 3-1 to the center from pressing plate 3 edges on pressing plate 3, be used for oil pipe end and snap in pressing plate 3.
As shown in Figure 4, oil pipe end 14 sticks into pressing plate 3 centers, and is blocked by nut 15, oil pipe end 14 is stuck in pressing plate 3 times like this, and when pressing plate 3 moves downward, oil pipe end 14 is pushed down, withstand the opening on spool 7 tops, the cavity 7-1 docking in oil pipe and spool 7 forms path.As shown by the arrows in Figure 2, high-pressure cleaning liquid flows to and is: the valve core through hole 7-2 of the space between base plate 11 central through holes, spool 7 and chuck body 6, spool 7 sidewalls, spool 7 internal cavity 7-1 finally enter the oil pipe inner chamber.Complete when cleaning, rotary handle 1 unclamps clamping cap 2, and spool 7 is by jack-up, and the sealed circle 9 of described valve core through hole 7-2 seals, and the cleaning fluid of below no longer flows into the cavity 7-1 in spool 7.Can draw off oil pipe end 14 and nut 15 this moment.
