Abstract
The utility model discloses a kind of water test units for detecting GRP pipe circumferential direction failure intensity, blind flange including GRP pipe and set on the GRP pipe both ends, the circumferential direction of blind flange, which extends, is equipped with connecting tube, GRP pipe is bonded and wraps up by the connecting tube, sticking part is equipped with multi-layer sealed circle side by side and is connected and sealed, and the end joining place of blind flange and GRP pipe is sealed equipped with rubber pad.The device has multi-layer sealed effect, rubber pad guarantees sealing effect by the pressure of fastening screw first, multilayer O-ring reaches sealing effect by interior hydraulically-formed glass reinforced plastic pipe expansive force compressing rubber circle, so that the device has axial constraint effect, when guaranteeing that GRP pipe bears interior hydraulic pressure, axially loaded is lower than the 1/2 of circumferential stress, so that circumferential intensity fails prior to axial strength, the failure intensity of acquisition is circumferential failure intensity, safe and efficient.
Description
Technical field
The utility model belongs to pipeline field more particularly to a kind of hydraulic pressure examination for detecting GRP pipe circumferential direction failure intensity
Experiment device.
Background technique
GRP pipe is a kind of lightweight, high-strength, corrosion resistant nonmetal pipeline, and structural pipe wall is rationally advanced, can fill
The effect that material is waved in distribution optimizes all directions intensity distribution under the precursor for meeting use intensity, ensure that the reliable of product
Property and economy, application field are extensive.For the security reliability for further increasing the quality of glass reinforced plastic pipe product and using,
Each glass reinforced plastic pipe manufacturing firm all is making great efforts to strengthen inspection and research technique.
The circumferential failure intensity value of GRP pipe is different with axial failure intensity value, and GRP pipe is by interior hydraulic pressure
When, circumferential the ratio between stress and axially loaded are 2:1；Interior hydraulic pressure failure intensity detection is carried out to GRP pipe, works as glass reinforced plastic
The axial failure intensity of pipeline is lower than the 1/2 of circumferential failure intensity, and under unconstrained state, what is failed first is GRP pipe
Axial strength, and what is actually obtained is axial failure intensity；Therefore, the failure intensity water pressure test of GRP pipe circumferential direction is carried out
When, the axially loaded of GRP pipe need to be constrained.
Utility model content
Purpose of utility model: the purpose of this utility model be it is a kind of can the axially loaded effectively to GRP pipe carry out
Constraint, and then can efficiently and safely test the water test unit of GRP pipe circumferential direction failure intensity.
Technical solution: the utility model detects the water test unit of GRP pipe circumferential direction failure intensity, including glass
Steel conduit and blind flange set on the GRP pipe both ends, the circumferential direction of the blind flange, which extends, is equipped with connecting tube, the connection
GRP pipe is bonded and wraps up by pipe, and sticking part is equipped with multi-layer sealed circle side by side and is connected and sealed, the blind flange and glass
The end joining place of steel conduit is sealed equipped with rubber pad.Preferably, sealing ring is " O " type sealing ring.
Furtherly, water inlet and water outlet, glass are offered on one end blind flange of the GRP pipe of the utility model
The other end blind flange of glass steel conduit is equipped with exhaust outlet.Water pump is connected at inlet and outlet.
It further says, the device of the utility model includes the pressure test table for detecting hydraulic pressure in GRP pipe.
Furtherly, the device of the utility model further includes the connection that the blind flange at GRP pipe both ends is connected
Bar.Connecting rod is fixedly connected on blind flange by nut.
The utility model has the advantages that compared with prior art, the advantages of the utility model are as follows: the device has multi-layer sealed effect, first
First rubber pad guarantees sealing effect by the pressure of fastening screw, and multilayer O-ring is by interior hydraulically-formed glass reinforced plastic pipe expansion
It forces contracting rubber ring and reaches sealing effect, so that the present apparatus has axial constraint effect, guarantee in GRP pipe receiving
When hydraulic pressure, axially loaded is lower than the 1/2 of circumferential stress, so that circumferential intensity fails prior to axial strength, the failure intensity of acquisition
It is safe and efficient for circumferential failure intensity.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of utility model device.
Specific embodiment
The technical solution of the utility model is described in further details with reference to the accompanying drawing.
The water test unit of the detection GRP pipe circumferential direction failure intensity of the utility model, including GRP pipe 1,
The both ends of the GRP pipe 1 are equipped with blind flange 2, and the circumferential direction of the blind flange 2 at both ends extends towards the middle part of GRP pipe
Equipped with connecting tube 3, the both ends of GRP pipe 2 are bonded package by connecting tube 3, and the fitting position setting multilayer of the two is O-shaped close
Seal 4, it is preferred that two layers of O-ring seal 4, blind flange 2 and the GRP pipe 1 at 1 both ends of GRP pipe is set side by side
End joining place is equipped with rubber pad 5 and is connected and sealed, and the blind flange 2 at 1 both ends of GRP pipe is connected by connecting rod 6,
And fixed by nut, as shown in Figure 1.
Wherein, offer water inlet and water outlet on one end blind flange 2 of GRP pipe 1, GRP pipe 1 it is another
One end blind flange 2 is equipped with exhaust outlet.Water pump is connected at inlet and outlet.The device further includes for detecting glass
The pressure test table of hydraulic pressure in steel conduit 1.
The principle detected using the above-mentioned device of the utility model are as follows: injected by water inlet into GRP pipe
Water source, and the gas in GRP pipe is discharged by exhaust outlet, it constantly injects water source and is supervised by pressure test table
It surveys.
