Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, the present invention includes screw rod 1 and the fixing nut 10, close installed successively from bottom to up along screw rod 1
Seal 9, the first packing ring 8, lower chock plug 7, breathing chuck 6, upper chock plug 5, second packing ring 4 and traveling nut 2.It is fixing nut 10, close
Seal 9, the first packing ring 8, lower chock plug 7, breathing chuck 6, upper chock plug 5, second packing ring 4 are sequentially overlapped, close connection.First packing ring
8 between lower chock plug 7 and sealing ring 9 so that and lower chock plug 7 does not contact directly with sealing ring 9, play the work for protecting sealing ring 9
With again do not stay gap.Second packing ring 4 avoids traveling nut 2 from being ground in rotation process between traveling nut 2 and upper chock plug 5
Chock plug 5 in damage, reduce contact area, the application of pressure are influenced, so as to influence sealing effect.
Fixing nut 10 is fixedly connected with screw rod 1, and as supporting part, support is sequentially overlapped each accessory on it.
Sealing ring 9, the first packing ring 8, lower chock plug 7, breathing chuck 6, upper chock plug 5, the centre of second packing ring 4 are equipped with through hole,
Screw rod 1 is sealed through sealing ring 9, the first packing ring 8, lower chock plug 7, breathing chuck 6, upper chock plug 5, the through hole of second packing ring 4
The 9, first packing ring 8 of circle, lower chock plug 7, breathing chuck 6, upper chock plug 5, second packing ring 4 can move freely on screw rod 1, replacement side
Just, and alternatively it is applicable in the mouth of pipe without specification.
The outside welding rotation handle 3 of traveling nut 2, traveling nut 2 are threadedly coupled with screw rod 1.Rotation handle 3 is rotated,
Traveling nut 2 is moved along 1 screw thread of screw rod.The main function of traveling nut 2 is pressed to upper chock plug 5, promotes it to press down, and
Breathing chuck 6 and sealing ring 9 is set to be stretched toward both sides.
As shown in Fig. 2, the top half of the latter half of upper chock plug 5 and lower chock plug 7 is pyramidal structure, it is taper respectively
Structure 50 and pyramidal structure 70, the upper port 60 and lower port 62 of breathing chuck 6, which are respectively equipped with, disposes the taper of pyramidal structure recessed
Mouthful.The side wall of the pyramidal structure of upper chock plug 5 and lower chock plug 7 and the angle β of vertical direction are more than the madial wall of conical depression with erecting
Nogata to angle α.Such size design applies pressure to breathing chuck 6 easy to upper chock plug 5, easily produces extruding force, and produce
The contact surface of extruding force is big, promotes breathing chuck 6 to be stretched toward both sides.
The outer wall of breathing chuck 6 is equipped with annular groove 61.After breathing chuck 6 comes into full contact with inside pipe wall, annular groove 61
Gap is left with inside pipe wall, after the releasing of 6 received extruding force of breathing chuck, breathing chuck 6 can easily divide with inside pipe wall
From avoiding breathing chuck 6 and inside pipe wall and completely attach to, form the state of vacuum, be not easy to separate.
Sealing ring 9 at least two, successively installation side by side.Sealing ring 9 is used as sealed source, and seal is more, sealing effect
Better.
The outside diameter of the upper surface of upper chock plug 5 is more than the outside diameter of sealing ring 9.The outside diameter of sealing ring 9 matches with nozzle diameter,
The outside diameter and the diameter more than the mouth of pipe of so upper 5 upper surface of chock plug, therefore on applying pressure to during chock plug 5, upper chock plug 5 is not
The mouth of pipe can be fully sunk in, and can be come into full contact with traveling nut 10, upper chock plug 5 is brought pressure to bear on easy to traveling nut 10.
