Abstract
The utility model relates to a special ring flange for connecting various pipelines and gate valves, which mainly comprises a flange body and a connecting tube embedded in the flange body. The utility model is characterized in that two seal grooves are arranged on the flange body, a plurality of sealing rings are arranged respectively in the seal grooves. Two semicircular lock grooves with same shape and dimension are positioned respectively in the inner bore of the flange body and on the connecting tube. A plurality of lock steel balls are positioned in the space created by the two semicircular lock grooves. Compared with the prior art, the utility model can realize the random rotation and the rotation about an axis of the flange body or of the connecting tube and can greatly enhance the work efficiency of installation and maintenance of the pipelines and the gate valves, moreover, the utility model has the advantages that the structure is simple, the product is easy to process and implement.
Description
The utility model relates to a kind of special flange dish that various pipelines are connected with gate valve.
In used pipeline and gate valve flange connecting, mainly contain two kinds of structures: a kind of is that the connecting tube of flange plate and flange body are welded together; Another kind is to adopt screw thread that the connecting tube of flange plate and flange body are linked together.All there are two very big defectives in the flange plate of these two kinds of structures: the one, and the flange body blue disk axis of winding separately rotates, in case when needing to rotate because of installing or keeping in repair, flange body must rotate with connecting tube, and connecting tube often is subjected to the restriction of the other end flange plate and connection gate valve mounting point thereof and does not allow to rotate, and has so just caused flange body not rotate by certain requirement winding orchid disk axis; The 2nd, flange body can not move along the flange plate axis separately, in case because of installing or maintenance needs when mobile, flange body must move with connecting tube, and connecting tube is under general situation, because of can't move along the flange plate axis by the link position restriction, so just caused flange body not move along axis by certain requirement.These two defectives have caused the installation, maintenance work difficulty of the pipeline that connects with flange plate at need and gate valve very big, the high pressure flange dish of some specific uses particularly, because of limited by service condition, do not allow welding between two flange plate, be threaded and must adopt, in order to guarantee the sealing of connecting thread, connecting thread is tightened moment of torsion in accordance with regulations, so just caused the position of flange body upper bolt hole to be difficult to determine.
The purpose of this utility model provides a kind of adjustable flange plate, and it can not only make the blue disk axis of flange body winding rotate arbitrarily, and can make flange body make corresponding mobile along the flange plate axis.
Realize that the technological scheme that the purpose of this utility model adopted is:
This flange plate mainly is made up of flange body and the connecting tube that is set in it.Be characterized in: the flange body endoporus is provided with two seal grooves, and seal ring is housed respectively in the seal groove.On the left side of seal groove one locking steel ball pilot hole is arranged, a semicircle type locking slot is arranged at locking steel ball pilot hole bottom, in the internal thread on locking steel ball pilot hole top a sunk screw plug is arranged.The semicircle type locking slot of one identical shaped and size is arranged on the position of the corresponding locking of connecting tube steel ball pilot hole semicircle type locking slot, and the space that forms at two semicircle type locking slots is built-in with some locking steel balls.Left end at flange body locking steel ball pilot hole has a fixing screw hole, on the position of the corresponding fixing screw hole of connecting tube a semicircle type positioning hole is arranged, and countersunk head set screw pin lower end is pressed on the positioning hole by fixing screw hole.
Adopt the model utility of technique scheme, the blue disk axis of flange body winding is rotated arbitrarily, can also make flange body make corresponding mobile along the flange plate axis, satisfy various need the use in pipeline that flange plate connect and the gate valve and use, can improve pipeline and gate valve installation, maintenance working efficiency greatly, and its simple in structure, easy processing, easily implement.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is adjustable flange plate and gate valve flange connection diagram.
Fig. 3 is the A-A sectional drawing of Fig. 1.
1. flange bodies, 2. seal grooves, 3. seal grooves, 4. connecting tubes, 5. seal rings, 6. seal rings, 7. sunk screw plugs, 8. sunk screw pins, 9. semicircle type locking slots, 10. locking steel balls, 11. semicircle type locking slots, 12. fixing screw holes, 13. semicircle type positioning holes, 14. locking 16. connecting bolts, 17. connecting bolt holes, steel ball pilot hole 15. connecting bolt holes 18. nuts, 19. nuts, 20. gate valve flanges, 21. gasket rings among the figure
Referring to Fig. 1-Fig. 3, be provided with two seal grooves 2,3 at the middle part of flange body 1 endoporus, seal ring 5,6 is housed respectively in the seal groove 2,3.On the left side of seal groove 2 a locking steel ball pilot hole 14 is arranged, a semicircle type locking slot 9 is arranged at the bottom of locking steel ball pilot hole 14, in the internal thread on the top of locking steel ball pilot hole 14 a sunk screw plug 7 is arranged.The semicircle type locking slot 11 that one identical shaped and size is arranged on the position of the semicircle type locking slot 9 of the corresponding locking of connecting tube 4 steel ball pilot holes 14 bottoms.The space that forms at two semicircle type locking slots 9,11 is built-in with some locking steel balls 10.Left end at flange body 1 has a fixing screw hole 12, and a semicircle type positioning hole 13 is arranged on the position of connecting tube 4 corresponding fixing screw holes 12, and countersunk head set screw pin 8 lower ends are pressed on the semicircle type positioning hole 13 by fixing screw hole.
Referring to Fig. 2, connecting bolt 16 passes connecting bolt hole 15,17, connecting bolt 16 two ends link together the flange 20 of the flange body 1 of adjustable flange plate with gate valve with nut 18,19, the flange body 1 of the adjustable flange plate of gasket ring 21 sealings and the end face of the flange 20 of gate valve make the endoporus of two flange plate can not communicate with the external world.Seal ring 5,6 is the outer rim of sealed joint pipe 4 and the gap between flange body 1 endoporus effectively.Locking steel ball 10 by semicircle type locking slot 9 on the flange body 1 and the semicircle type locking slot 11 on the connecting tube 4, is linked to be an integral body to flange body 1 and connecting tube 4.Unclamp set screw pin 8, locking steel ball 10 rotates flange body 1 or connecting tube 4 flexibly.Unclamp set screw pin 8, locking steel ball 10 is taken out, can realize that flange body 1 is moved to the left or connecting tube 4 moves right along axis along axis.Flange body 1 reinstalls 9,11 li of locking slots to locking steel ball 10 with before gate valve flange 20 is connected, and tightens sunk screw plug 7, tightens sunk screw pin 8 and promptly realizes resetting.
