Model utility content
The technical problems to be solved in the utility model is to provide the connection set of the better high-pressure oil pipe of a kind of sealing effect.
In order to solve the problems of the technologies described above, the connection set of high-pressure oil pipe of the present utility model, comprises U-shaped pipe, pad and flange plate; The mouth of pipe place of described U-shaped pipe is provided with conical pipe, and the outer wall of described conical pipe is taper; It is equal with the external diameter of described U-shaped pipe and be less than the external diameter of the other end that described conical pipe connects the external diameter of U-shaped pipe one end; Described pad is socketed on outside described U-shaped pipe; Described pad is funnel shape pad, and described pad comprises interconnective taper pad and cylindricality sleeve pipe; Described taper pad is towards described conical pipe, and geomery and the described conical pipe boundary dimension of described taper pad inner chamber are suitable; Described cylindrical sleeve bore and described U-shaped pipe external diameter suitable; Described flange plate is socketed on outside described U-shaped pipe by sleeve joint hole; Described sleeve joint hole comprises the taper sleeve joint hole and cylindricality sleeve joint hole that are interconnected; The geomery of described taper sleeve joint hole and the boundary dimension of described taper pad suitable and towards described taper pad; The geomery of described cylindricality sleeve joint hole and the boundary dimension of described cylindricality sleeve pipe suitable; Described flange plate two ends are symmetrically arranged with bolt hole.
Two mouth of pipe places of described U-shaped pipe are provided with described conical pipe, pad and flange plate.
Described flange plate two ends are symmetrically arranged with two bolts hole respectively.
Described conical pipe inwall is cylindrical, and the internal diameter of described conical pipe is equal with the internal diameter of described U-shaped pipe.
The outer wall of described conical pipe is conical.
Adopt structure of the present utility model, due to the funnel shape pad arranging conical pipe and correspondence at U-shaped pipe mouth of pipe place, the distortion of pad can be reduced, even can increase the thickness of pad, thus make up the distortion under flange plate pressure, thus improve sealing effect.Taper sleeve joint hole and the cylindricality sleeve joint hole of corresponding pad are set in flange plate, because capacity is fixed, the deformation of conical pipe can be controlled, thus avoid U-tube and conical pipe to break, reduce the generation in gap, improve sealing effect.

Fig. 2 is the structural representation of flange plate in Fig. 1;
Fig. 3 is the structural representation of Fig. 1 Intermediate gasket.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1, Figure 2 and Figure 3, the connection set of high-pressure oil pipe of the present utility model, comprises U-shaped pipe 1, pad 3 and flange plate 2.
The mouth of pipe place of U-shaped pipe is provided with conical pipe 4, and the outer wall of conical pipe is taper.It is equal with the external diameter of U-shaped pipe and be less than the external diameter of the other end that conical pipe connects the external diameter of U-shaped pipe one end.The shape of conical pipe can be circular cone, triangular pyramid or rectangular pyramid etc.By arranging conical pipe, pad and flange plate can be avoided to come off.Adopt U-shaped pipe due to certain elastic strain can be produced, certain buffering can be obtained in the process that high-pressure oil pipe is run at equipment, reduce high-pressure oil pipe and be out of shape and break.
Pad is socketed on outside U-shaped pipe.U-shaped pipe is through the two ends of pad.Pad is funnel shape pad, and pad comprises interconnective taper pad 32 and cylindricality sleeve pipe 31.Taper pad is towards conical pipe, and geomery and the conical pipe boundary dimension of taper pad inner chamber are suitable, can be the circular cone corresponding with conical pipe, triangular pyramid or rectangular pyramid etc., can closely be socketed in outside conical pipe to make taper pad.By arranging taper pad, taper pad can be avoided to be crushed under the pressure of flange plate and to produce gap, making taper pad thickening under compression on the contrary, thus make more to seal between conical pipe and flange plate.Cylindrical sleeve bore and U-shaped pipe external diameter suitable, the profile of cylindricality sleeve pipe can be tri-prism, quadrangular or cylinder etc.Being fixedly connected with taper pad by arranging cylindricality sleeve pipe, taper pad can being made up and compressed under flange plate pressure, improve sealing.
Flange plate is socketed on outside U-shaped pipe by sleeve joint hole.U-shaped pipe passes flange plate two ends from sleeve joint hole.Sleeve joint hole comprises the taper sleeve joint hole 21 and cylindricality sleeve joint hole 22 that are interconnected.The geomery of taper sleeve joint hole and the boundary dimension of taper pad is suitable and towards taper pad, the shape of taper sleeve joint hole can be circular cone, triangular pyramid or the rectangular pyramid etc. corresponding with taper pad, to make more to seal between pad and flange plate.The geomery of cylindricality sleeve joint hole and the boundary dimension of cylindricality sleeve pipe suitable, can be tri-prism, quadrangular or cylinder etc.The length of cylindricality sleeve joint hole is less than or equal to the length of cylindricality sleeve pipe, can reduce between flange plate and U-shaped pipe and have gap, improves sealing, improves the soundness of flange plate.Flange plate two ends are symmetrically arranged with bolt hole 23.By arranging bolt hole, by bolt by corresponding with the flange plate of high-pressure oil pipe for flange plate fixing, time as connected two U-shaped pipes, can be bolted to connection by the flange plate of bolt by two U-shaped pipes, thus two U-shaped seals of tube are communicated with.By all arranging bolt hole at flange plate two ends, making to connect between flange plate more accurate, improving the connection sealing that high-pressure oil pipe connects U-shaped pipe.
As shown in Figure 1, two mouth of pipe places of U-shaped pipe are provided with conical pipe, pad and flange plate, and the high-pressure oil pipe that U-shaped pipe two ends are connected all can improve the sealing effect of connection.
As shown in Figure 2, flange plate two ends are symmetrically arranged with two bolts hole respectively, arrange more bolt hole and make to connect more firm, can improve the sealing effect of connection further.
As shown in Figure 1, conical pipe inwall is cylindrical, and the internal diameter of conical pipe is equal with the internal diameter of U-shaped pipe.Conical pipe inwall is cylindrical, and namely conical pipe inner chamber is cylindrical, and conical pipe outer wall is taper, thus improves the pipe thickness of conical pipe, reduces and is out of shape because of flange plate pressure and breaks, and improves sealing effect, improves and connects compact type.
As shown in Figure 1, the outer wall of conical pipe is conical, makes the gap between pad less, uniform force, thus makes the sealing effect of connection better.
