Abstract

The utility model provides a fast assembly joint for clamping pipes, which belongs to the field of pipe joints and is mainly used for assembly and disassembly of the connection of rubber pipes of large pipe diameters. The fast assembly joint for clamping pipes is composed of a clamping device, two pipe sleeves 3 for outer flanges, two inner pipes 1 and a sealing pad 5. The utility model uses a pipe clamp to replace a plurality of clamping screws which are used in the existing joints for clamping pipes, so the utility model has the advantages of convenient assembly and disassembly and reliable installation, and reduces the labor intensity of operators.

Description

Fast assembling clasp joint for pipe

The utility model belongs to the pipe joint field.

The existing card pipe joint that is used for big caliber sebific duct connection, its clamp device realizes that by many bolts that were distributed in for two outward flange pipe box flange edge garden weeks when practical operation, mounting or dismounting bother, the mounting or dismounting of connecting for big caliber sebific duct bring very big inconvenience, and labor intensity of operating staff is big.

The purpose of this utility model is: a kind of fast assembling-disassembling card pipe joint that big caliber sebific duct connects that is mainly used in is provided, makes its dismounting easy, alleviate labor intensity of operating staff.

The technical solution of the utility model is: the quick-mounting clamp pipe joint, by clamp device; Two outward flange pipe boxes 3, pipe 1 and sealing gasket 5 are formed in two, the pipe clamp 4 that its special way is that clamp device is that two one ends are hinged, the other end can be made up of the half garden ring of tightening after on the bolt card, two halves garden ring inner ring is the draw-in groove of indent, the draw-in groove section is isosceles trapezoid, and one of them half garden ring radially has a strip through-hole; Two outward flanges, pipe box 3 end flange limit sections are corresponding with pipe clamp 4 inner ring draw-in grooves trapezoidal.Its special way is that also the trapezoidal cross-section hypotenuse angle on pipe clamp 4 inner ring draw-in grooves and two outward flange pipe boxes, 3 end flange limits is 5 °～30 °.

The utility model so dismounting has easily improved labor intensity of operating staff, and is installed reliable owing to replaced many bolts as clamp device with pipe clamp.

Cross-sectional schematic when Fig. 1 uses for the utility model,

Fig. 2 is the utility model pipe clamp schematic representation,

Fig. 3 is existing card pipe joint schematic representation.

Below in conjunction with description of drawings the utility model embodiment: as Fig. 1, the quick-mounting clamp pipe joint is by clamp device, two outward flange pipe boxes 3, pipe clamp 4(Fig. 2 that pipe 1 and sealing gasket 5 form that its clamp devices are that two one ends are hinged in two, the other end can be formed with the half garden ring of tightening after on the bolt card), two halves garden ring inner ring is the draw-in groove of indent, the draw-in groove section is the isosceles trapezoid of 5 °～30 ° of hypotenuse angles, to guarantee that certain radially clamping force is converted into axial pressure, one of them half garden ring radially has a strip through-hole, stretches out for sealing gasket 5 ends; Two outward flange pipe boxes, 3 end flange limit sections are the trapezoidal of pipe clamp 4 inner ring draw-in groove correspondences, and its hypotenuse angle also is 5 °～30 °.

When dismounting, tight a bolt or looser a bolt, take off pipe clamp 4 after only needing to block pipe clamp 4 upward and can realize connecting or taking apart sebific duct 2 quickly and easily.Both reduced labor intensity, installed reliable again.

Claims

1, a kind of quick-mounting clamp pipe joint, by clamp device, two outward flange pipe boxes 3, pipe 1 and sealing gasket 5 are formed in two, the pipe clamp 4 that it is characterized in that clamp device is that two one ends are hinged, the other end can be made of the half garden ring of tightening after on the bolt card, two halves garden ring inner ring is the draw-in groove of indent, and the draw-in groove section is isosceles trapezoid, and one of them half garden ring radially has a strip through-hole; Two outward flange pipe boxes, 3 end flange limit sections are corresponding with pipe clamp 4 inner ring draw-in grooves trapezoidal.

2, quick-mounting clamp pipe joint according to claim 1 is characterized in that the trapezoidal cross-section hypotenuse angle on pipe clamp 4 inner ring draw-in grooves and two outward flange pipe boxes, 3 end flange limits is 5 °～30 °.
