The further improvement project of the utility model is that one end that the water injection pipe is connect with piston rod end passes through fixation Sealing plate A sealing is connected, the one end of the exhaust pipe far from water injection pipe is sealed by being fixedly connected with sealing plate B.
The further improvement project of the utility model is that the water injection pipe is fixed with the flanged plate A for connecting measured tube, The exhaust pipe is fixed with the flanged plate B for connecting measured tube towards one end of water injection pipe.
The further improvement project of the utility model is that the water injection pipe is connected to by water inlet pipe with water pump, the water inlet Connection is equipped with water injection valve on pipe.
The further improvement project of the utility model is that the snorkel is equipped with exhaust valve.
The further improvement project of the utility model is to be respectively provided with support water filling on the bracket A and bracket B The support base of pipe, measured tube or exhaust pipe.
The further improvement project of the utility model is that the support base includes pedestal, and the lower end of the pedestal is fixed on Bracket A or bracket B, the top of the pedestal are equipped with pressing plate corresponding with water injection pipe, measured tube and exhaust pipe outside diameter, the pressure One end of plate is movably connected with the base by loose-leaf, and the other end of the pressing plate is fixedly connected by bolt with pedestal.
The utility model compared with prior art, has following obvious advantage:
One, preload pressure is provided to pipeline using jack, realizes that water injection pipe, measured tube are connected to exhaust pipe, is not necessarily to It is fastenedly connected using bolt, can be improved detection efficiency, reduce old.
Two, one end that water injection pipe and exhaust pipe are not connect with measured tube is sealed using sealing plate A and sealing plate B, is connected Structure is simple.
Three, in the connecting pin mounting flange plate of water injection pipe and exhaust pipe and measured tube, can facilitate water injection pipe, exhaust pipe with Connection between measured tube.
Four, water pump is connect by water injection valve with water injection pipe, can be prevented when hydraulic pressure is excessive, water flow is overflowed from water inlet pipe Come.
Five, snorkel is equipped with exhaust valve, can prevent the generation of " vent plug " phenomenon, can once reach boost effect, Without boosting repeatedly, to improve working efficiency.
Six, in the lower section of water injection pipe, measured tube and exhaust pipe, setting support base can enhance the stability that pipeline connects.
Detailed description of the invention
Fig. 1 is a kind of schematic front view of pipe flange detection device;
Fig. 2 is the schematic front view of support base.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, the utility model includes horizontal jack 1, and jack 1 is fixed on bracket A2, jack 1 Piston rod end be fixed on one end of water injection pipe 4, one end that the water injection pipe 4 is connect with piston rod end is welded with sealing plate A41 sealing.The other end of water injection pipe 4 is welded with flanged plate 42, and flanged plate 42 is bonded phase with the flanged plate 61 of 6 one end of measured tube It is logical.The tube wall of water injection pipe 4 is respectively communicated with equipped with water pump 7, pressure gauge 44 and drainpipe 45, and connection is equipped with draining on drainpipe 45 Valve.Water injection pipe 4 is connected to by water inlet pipe 43 with water pump 7, and connection is equipped with water injection valve on water inlet pipe 43.
Water injection pipe 4 is coaxially arranged with exhaust pipe 5, and exhaust pipe 5 is fixed on bracket B8, the one end of exhaust pipe 5 towards water injection pipe 4 It is welded with flanged plate 53, flanged plate 53 is connect with the other end flanged plate 62 of measured tube 6.The one end of exhaust pipe 5 far from water injection pipe 4 It is welded with sealing plate B51 sealing.The tube wall of the exhaust pipe 5 is communicated with snorkel 52, and snorkel 52 is equipped with exhaust valve.
