Description
The present invention relates to the clamping element of a kind of annular garden plate-like, being used to connect two the pipe terminations that will dock mutually connects together, a flange plate that can easily promote or like parts are respectively arranged on two pipe terminations, they can clamp mutually, two flange plate respectively have the annular chamber of a clamping usefulness, a clamping element that can promote is respectively arranged on each pipe termination, clamping element can be inserted in the annular chamber and go, clamping element relies on the warp-wise gripper edge of inner ring to be bearing on the pipe termination, because the radially gripper edge of the outer ring of clamping element and the gripping surface of flange plate annular chamber overlap joint, the clamping element external diameter that axially causes that is added in clamping element increases, internal diameter dwindles, and gives at the seam crossing around butt joint again and has placed seal ring earlier.
Above-mentioned pipe connects can take from European publication file 0087702.This pipe connection can be assemblied in smooth, has only gone on the pipe termination of burr, and at this moment, it is suitable only to need as unique assembling supplementary means, the wrench of the usefulness that tights a bolt.The dismounting that pipe connects is also very simple.This structure for the sealing of high pressure, confirms very effective in practice especially.
With regard to this known structure, each clamping element becomes the garden dish of convex to constitute by one at least, and this garden dish can become dish shape spring, perhaps become toothed, the clamping element of garden plate-like.Each clamping element radially, the gripper edge on the inner ring can sharpening, so just can under the effect of power, attach the slight distortion closure of formation between clamping element and tube outer wall when tightening pipe and connect.
A kind of similar pipe connects also can use F.P. 2237102.In this special use, clamping element is become narrower plane inclination into about 30.But studies show that, tilt big like this clamping element when tightening the pipe connection, generally can change plastic deformation over to from resiliently deformable, reach to the original function of clamping element and after assembling, can not get guaranteeing, in addition, the oblique position of this form needs Bolt Connection to produce very big power, and this just forces people to adopt than the much bigger Bolt Connection of this class pipe connection size.
If the pipe that is coupled to each other is by brittle material,, connects with the pipe of setting forth at the beginning and also can go wrong for example by containing phenolic resin and filler is formed.When tightening the pipe connection, the ascending pipe sub-surface, the gripper edge on the inner ring of clamping element causes the fracture of body sometimes.
Task of the present invention is, in practice for very successful pipe connects the clamping element that development makes new advances, with the application area of this novel clamping element energy enlarged pipe connection.
The method that the present invention finishes this task is that the ring part of clamping element is made certain shape.
At this moment, the cross section of the ring part of clamping element can be an arc shaped surface, and this arc shaped surface mainly determined by a radius, and forms arc of the identical garden shape of thickness.
Use such clamping element, when the bending of radius changes, can calculate and determine a stroke that becomes with structure height.If arc-shaped sections is arranged to the plane inclination of clamping element in an acute angle, this stroke can also greatly increase.Can under the very little situation of structure, obtain very considerable big stroke with this class clamping element.Here saying that give an example in the tilt angle of being mentioned can be 15 °.
According to another kind of scheme, the annular of clamping element can be made of the constant outer garden ring of width, and inside, the fish plate that is approximated to the tangent line trend with the clamping element inner diameter hangs on the ring of outer garden, and fish plate is tapered towards its empty end.This fish plate can have good coupling according to the spring characteristic curve and the tube outer diameter of clamping element material.According to the difference of the oblique position in slit and be used on the pipe with different masterpieces, at this moment spring pressure can be transferred softerly, thereby adapts to more crisp and harder tubing, for example plastic pipe, use softer spring, the pipe that for example is made of the PYC material also has this advantage again.
The ring part of clamping element can have the fish plate that is made of the slit its outer placing, and the outer diameter of these fish plates and clamping element is approximated to the tangent line trend.Concerning this class clamping element, if one radially, slit on the inner ring and one are radially, slit on the outer ring resembles mutual convergence the arrow, just more favourable, outer slit of Gou Chenging and interior slit just in the arrow scope, link together on the Zhou Fangxiang of garden like this, at this moment, the slit of subordinate can form about 120 ° angle mutually.This clamping element is specially adapted to very the not pipe in garden, and those inwalls have coating or wall very thin thereby can only bear the pipe of very little mechanical force, for this clamping element, can make the arrow-shaped of cutting off in the middle of constituting become nominal fracture position, like this, the dish-shaped piece of each horn shape arrangement just constitutes has separately had the clamping element of spring performance one by one.This clamping element also can influence on the very sensitive pipe mechanical property when being used in those devices in two.
The ring part of clamping element also can be made of a narrow outer garden ring, and inside radially fish plate hangs on the ring of this garden.This class only has the clamping element of inside radial gap when tightening the pipe connection, needs sizable tension moment.But the power of radial effect on flange plate parts and re-entrant part is very little, and this point is for by more crisp material, for example the re-entrant part and the flange plate parts advantageous particularly that constitute of aluminium or plastics.
In the structural type of another kind of slight change, the existing inside radial gap of the ring part of clamping element, also have and be arranged between these slits, recess on the outer ring, at this moment comparatively favourable way is, make the radial depth big manyfold of the length of radial gap than recess, when tightening the pipe connection, this clamping element only needs less tension moment, the radial force that but acts on re-entrant part and the flange plate parts is very big, particularly the tube outer diameter that is in the positive error scope is had this situation, this clamping element is suitable for by by the flange plate parts and the re-entrant part that for example constitute by the Tough material of DIN17100.
For the clamping element that radial gap is only arranged on inner ring, if ring part is cut just more favourable on a certain position.This class clamping element can be used on the steel pipe of glaze, because glaze is coated on the pipe shell, thereby causes the increase of pipe housing diameter.If the clamping element in the standard of use will damage the glaze layer on the pipe shell.The clamping element that cuts also can be used for coated pipe.
The material available quality of clamping element is the steel of CK75, and material also can use the cold-strip until C95 preferably through the Overheating Treatment austempering.
