Abstract
The invention discloses a quick coupling for pump test. One end of a seamless steel pipe A is connected with a flange, the other end of the stainless steel pipe A is connected with a male quick coupling body, and one end of a stainless steel pipe B is connected with a female quick coupling body, wherein the male quick coupling body is mutually matched with the female quick coupling body; a rotating ring is mounted on the male quick coupling body; a movable seat is mounted on the rotating ring; one end of a loose joint bolt is mounted on the movable seat, and the other end of the loose joint bolt is mounted on a clamping groove seat which is mounted on the female quick coupling body; the male quick coupling body and the female quick coupling body are fastened through the loose joint bolt and a nut. The quick coupling has the characteristics that the quick coupling is simple in structure and high in practicability; the workload of connection of a pump test pipeline is reduced, the test rate of a centrifugal pump is increased, the test time of the centrifugal pump is shortened, and can be saved by at least 30 percent, and all pump testing requirements can be met.
Description
Technical field
The present invention relates to Practical technical field, be specifically related to a kind of pump testing rapid pipe joint.
Background technique
Centrifugal pump is of a great variety at present, performance parameter is different, even same pump, because casting accuracy there are differences, field condition difference, fed sheet of a media difference, medium temperature is different ... each operating point is corresponding different performance parameter all, therefore, centrifugal pump is different from other batch productions, the product of stable performance, different on-the-spot service conditions requires us to test each pump, to reaching desired performance parameter, the test of pump is that workload is large naturally, a more step operation consuming time, in the past, in the connection of our factory pump testing pipeline, substantially all adopt flange to connect (certainly, some pipeline must adopt flange connection), this connecting means speed is slower, in the product demand growing with each passing day, raise the efficiency and seem particularly important.
Summary of the invention
The original DN200 bore of our factory adopts flange to connect with lower pipeline, connect component more, single pump pipeline connects consuming time more, therefore, the object of the invention is to reduce the workload that pump testing pipeline connects, improve the test rate of centrifugal pump, cancel the original flange of small-bore pump and connect, a kind of pump testing rapid pipe joint is provided.
The technological scheme that the present invention adopted is for achieving the above object: pump testing rapid pipe joint, seamless steel pipe A one end adpting flange, the other end connects the public body of rapid pipe joint, seamless steel pipe B one end connects rapid pipe joint parent, the public body of rapid pipe joint and rapid pipe joint parent cooperatively interact, on the public body of described rapid pipe joint, swivel becket is installed, active base is installed on swivel becket, loose joint bolt one end is arranged in active base, the other end is arranged on draw-in groove seat, described draw-in groove seat is arranged on rapid pipe joint parent, the public body of described rapid pipe joint and rapid pipe joint parent are by loose joint bolt, fastening nuts.
Between the public body of described rapid pipe joint and rapid pipe joint parent, pad is installed.
Described loose joint bolt is arranged in active base by straight pin.
The upper pressure measuring tie-in of installing of described seamless steel pipe A.
Feature of the present invention is: simple in structure, practicability is high, has reduced the workload that pump testing pipeline connects, and improves the test rate of centrifugal pump, shortens the centrifugal pump test time, can save at least 30% time, can realize all pump testing requirements.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Wherein: 1, flange 2, pressure measuring tie-in 3, seamless steel pipe A 4, swivel becket 5, active base 6, straight pin 7, the public body 8 of rapid pipe joint, rapid pipe joint parent 9, loose joint bolt 10, pad 11, draw-in groove seat 12, nut 13, seamless steel pipe B.
Embodiment
As shown in Figure 1, the present invention is pump testing rapid pipe joint: the upper pressure measuring tie-in 2 of installing of seamless steel pipe A3, described seamless steel pipe A3 one end adpting flange 1, the other end connects the public body 7 of rapid pipe joint, seamless steel pipe B13 one end connects rapid pipe joint parent 8, the public body 7 of rapid pipe joint cooperatively interacts with rapid pipe joint parent 8, and between the two, be provided with described in pad 10, on the public body 7 of rapid pipe joint, swivel becket 4 be installed, active base 5 is installed on swivel becket 4, loose joint bolt 9 one end are arranged in active base 5 by straight pin 6, the other end is arranged on draw-in groove seat 11, described draw-in groove seat 11 is arranged on rapid pipe joint parent 8, the public body 7 of described rapid pipe joint and rapid pipe joint parent 8 are by loose joint bolt 9, nut 12 is fastening.Number of assembling steps of the present invention: one, by flange 1, pressure measuring tie-in 2 and seamless steel pipe A3 welding; Two, swivel becket 4 is welded together with active base 5, and loose joint bolt 9 use straight pins 6 are fixed in active base; Three, the assembly of step 2 is packed on the seamless steel pipe A3 of step 1, and by welded together with seamless steel pipe A3 public rapid pipe joint body 7; Four, by welded together to draw-in groove seat 11, rapid pipe joint parent 8 and seamless steel pipe B13; Five, in rapid pipe joint parent 8, put into rubber sheet gasket 10, fastening by loose joint bolt 9, nut 12 with rapid pipe joint parent 8 public rapid pipe joint body 7.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technological scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
