The joint has the characteristics of reliable, reasonable and simple structure, simplicity in operation, low cost and the like.
Description
Technical field:
The present invention relates to the constituent field in the power electronics, relate more specifically to a kind of novel constituent joint.
Background technique:
Constituent is widely used in the direct-current transmission converter valve cooling current, and the pipe joint performance of constituent directly has influence on sealing, the switching performance of water circuit system.In the engineering practical application, owing to leakage and obstruction accident that the reason of water swivel causes are of common occurrence, therefore to the appropriate design of water pipe adapter with select that long-time running seems extremely important to converter valve for use.
The pipe collar Placement problem of current employing is more: the one, and the steel pipe collar is that silk is linked to each other with composite pipe (as polyethylene pipe), must keep straight during connection, takes a lot of work, takes material, difficulty of construction is big; The 2nd, when the composite pipe had bending or alignment error big, the easiest fracture was leaked; The 3rd, the steel pipe collar involves great expense.What another was commonly used is flanged ends, but the quality requirement of flange plate welding is higher, and it is solid reliable that weld seam is not only wanted, and also want sealability strong, and when the centre needs to change a pipe joint period of the day from 11 p.m. to 1 a.m, flange plate often is difficult to butt joint, and it is not corresponding a circular hole that connects to occur.
Summary of the invention:
The purpose of this invention is to provide a kind of novel constituent joint, have reliable, reasonable, easy structure, simple to operate during use, lower-price characteristic.
For achieving the above object, the present invention is by the following technical solutions:
A kind of novel constituent joint provided by the invention, comprise dowel screw and locking nut, described dowel screw inside is hollow, be provided with two taper bush between described dowel screw and the locking nut, the center of circle of described lining and the axis coinciding of described dowel screw, the conical surface shape of a described lining is identical with the interior shape of described dowel screw one end, and the conical surface shape of described another lining is identical with the interior shape of described locking nut one end.
In a kind of novel constituent joint technological scheme provided by the invention, described two taper bush adopt the relative arrangement in the awl end.
In another preferred a kind of novel constituent joint technological scheme provided by the invention, the top of a described lining extend in the end of described dowel screw, the sealing butt joint, dock with the bottom of another lining the bottom of a described lining, the bottom of described another lining extend in described locking nut one end, the sealing butt joint, an end of described dowel screw is connected with described locking nut one end.
In the preferred a kind of novel constituent joint technological scheme more provided by the invention, the end face away from nut one end on the cylindrical of described dowel screw has groove.
In another preferred a kind of novel constituent joint technological scheme provided by the invention, described cylindrical is positioned at the middle part of dowel screw.
In another preferred a kind of novel constituent joint technological scheme provided by the invention, described groove is furnished with the O RunddichtringO.
In another preferred a kind of novel constituent joint technological scheme provided by the invention, described O RunddichtringO is a rubber ring.
Because the beneficial effect that has adopted technique scheme, the present invention to obtain is:
1, water swivel dowel screw and radiator intake-outlet have good switching performance directly by the locking that is threaded, and quick-detach is easy for installation soon.
What 2, the O RunddichtringO adopted is that the high requirement of thread seal accuracy of screw machining has been avoided in end face seal, has excellent sealing performance.
3, economic performance: the Placement of this water swivel is compared with the flange Connecting format, but economical with materials expense 30%.
4, because it simple in structure, install, change convenient simple and direct, can improve 5～10 times of construction efficiency.
5, the water pressure resistance ability is strong, can bear 2MPa hydraulic pressure.
6, latus rectum is big, and flow resistance is little.

Fig. 1 is a kind of structural representation of novel constituent joint;
Fig. 2 is a kind of seal ring schematic representation of novel constituent joint;
Wherein, 1-dowel screw, 2-lining, 3-locking nut, 4-groove, 5-O RunddichtringO.
Embodiment
The invention will be described in further detail below in conjunction with embodiment.
Embodiment 1:
Shown in Fig. 1-2, a kind of novel constituent joint of this example invention, comprise dowel screw 1, locking nut 3, lining 2, groove 4 and O RunddichtringO 5, dowel screw 1 inside is the screw of hollow, be provided with lining 2 between dowel screw 1 and the locking nut 3, lining 2 is provided with two, two linings 2 are taper, the axis coinciding of the center of circle of lining 2 and dowel screw 1, the conical surface shape of a lining 2 is identical with the interior shape of dowel screw 1 one ends, and the conical surface shape of another lining 2 is identical with the interior shape of locking nut 3 one ends.
Two taper bush 2 adopt the relative arrangement in the awl end, the top of a lining 2 extend in the end of dowel screw 1, the sealing butt joint, dock with the bottom of another lining 2 bottom of a lining 2, the bottom of another lining 2 extend in described locking nut 3 one ends, the sealing butt joint, an end locking nut 3 one ends of dowel screw 1 connect.
End face away from nut one end on the cylindrical of dowel screw 1 has groove 4, and the cylindrical end face is at the middle part of dowel screw 1, and groove 4 is furnished with O RunddichtringO 5, and O RunddichtringO 5 is a rubber ring.
Dowel screw 1 outside thread directly is connected with the locking of radiator internal thread, and O RunddichtringO 5 is arranged on radiator intake-outlet end face, and O RunddichtringO 5 produces seal action with end face.When fluid pressure action during in fastened O RunddichtringO 5 inner chambers, the interior pressure that produces will be dispersed throughout the total inner surface of O RunddichtringO 5, the interior pressure that acts on O RunddichtringO 5 edges can produce bigger pressure to sealing surface, interior pressure is high more, the pressure of O RunddichtringO 5 is also big more, sealing effect is just obvious more, thereby prevents the leakage of fluid.
Water pipe inserts locking nut 3, lining 2 and dowel screw 1 successively, under locking nut 3 pretightening force effects, lining 2 one ends and dowel screw 1 form conical surface seal, and lining 2 the other ends and water pipe hug, avoid water to show out, play good sealing effect from pipe outer wall.
This water swivel advantage is that the water pressure resistance ability is strong, can bear 2MPa hydraulic pressure; Latus rectum is big, and flow resistance is little; The selfsealings performance is strong, anti-corrosive properties good, and is easy for installation, can guarantee long-time, highly reliable work, and joint can separate fast in use simultaneously, to make things convenient for the replacement of component maintenance.
Should be noted that at last: above embodiment is only in order to illustrate that technological scheme of the present invention is not intended to limit, although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement the specific embodiment of the present invention, and do not break away from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of this claim scope.
