The air bleeding valve can be removed after the completion of experiment.It is of course also possible to installation air bleeding valve be omitted, in water filling for a period of time afterwards by institute
Exhaust can equally be achieved the purpose that by stating gas vent and blocking.
Be referring next to Fig. 3, Fig. 3 the spigot-and-socket hydraulic pipeline pilot system of the utility model practical application in section
Figure.As shown in figure 3, after the end of the test, axial force-resisting positioning pin 5 can be mounted in the gas vent 28, the axial force-resisting is fixed
Position pin 5 and the gas vent 28 are detachably connected, and the axial force-resisting positioning pin 5 is used to prevent the socket pipeline 1 and described
Socket duct 2 is disconnected from each other.Specifically, it in order to ensure the safety of the socket type pipeline, is installed on the gas vent anti-
The axial force-resisting positioning pin 5 is threadedly coupled, the axial force-resisting by axle power positioning pin 5 with the gas vent 28 after the end of the test
Positioning pin 5 passes through the gas vent 28 but the not interior contact with first section 21, and design is advantageous in that in this way, i.e.,
So that the socket pipeline 1 and the socket duct 2 disengagement problem is occurred, the axial force-resisting positioning pin 5 can first with the interface
26 contact and limit the relative displacement between the socket pipeline 1 and the socket duct 2.In addition, the axial force-resisting positioning
Pin 5 is not in contact with the inner wall of first section 21, to not interfere with the spy of the socket type pipeline flexible interface rotation
Property.Although attached drawing with axial force-resisting positioning pin 5 be preferred embodiment be described, it is apparent that can be in other ways
It substitutes, such as locating ring.
It is finally the partial enlarged view of the spigot-and-socket hydraulic pipeline pilot system of the utility model refering to Fig. 4, Fig. 4.Such as Fig. 4
Shown, the axial force-resisting positioning pin is provided with 4 and is homogenously connected to the gas vent 28, and attached drawing is with 4 axial force-resistings
Positioning pin 5 is what preferred embodiment was described, it is apparent that the axial force-resisting positioning pin that other quantity can also be arranged is implemented.
Below in conjunction with the accompanying drawings to the application method and operation principle of the spigot-and-socket hydraulic pipeline pilot system of the utility model
It is described briefly.
Before on-test, first, the primary seal part 4 is installed in the interface portion, then, is inserted described
Mouth pipeline 1 is pushed into first section 21, and the experiment sealing ring 12 is installed on the rake 11, finally, pushes
The socket pipeline 1 makes the rake 11 be tightened against with second changeover portion 24.When starting experiment, first, it will try
Water is tested to be added in the toroidal cavity 3 by the water filling port 27, meanwhile, the gas vent 28 is opened, the annular is emptied
Then gas in cavity 3 waits for closing the gas vent 28 after gas discharge, finally, one section is stood after the completion of water filling pressurization
Time observes the water leakage situation of the connected pipeline.After the end of the test, first, the socket pipeline 1 is withdrawn into described
The experiment sealing ring 12 is then removed for use later, finally, is installed on the gas vent 28 by the first section 21
Axial force-resisting positioning pin 5 prevents the socket pipeline 1 and the socket duct 2 disconnected from each other.
So far, it has been combined preferred embodiment shown in the drawings and describes the technical solution of the utility model, still, this
Field technology personnel are it is easily understood that the scope of protection of the utility model is expressly not limited to these specific implementation modes.
Under the premise of the principles of the present invention, those skilled in the art can make the relevant technologies feature equivalent change
