Further, described aqueduct on-off system is electric gate valve, and described relief tube on-off system is electric gate valve.
Further, also comprise entrance flow switch and rate of discharge switch, described inlet flow rate switch is arranged on aqueduct, and described rate of discharge switch is arranged on relief tube.
Be further, also comprise controller, described controller comprises signal input part and signal output part, described inlet flow rate switch is connected with the signal input part of controller, described rate of discharge switch is connected with the signal input part of controller, and the electric gate valve that described aqueduct on-off system adopts, is connected with the signal output part of controller, the electric gate valve that described relief tube on-off system adopts, is connected with the signal output part of controller.
The beneficial effects of the utility model are: because the utility model is directly connected reservoir by aqueduct with pressurized water seal, utilize the existing hydraulic pressure of reservoir to carry out pressurising to pressurized water seal, thereby saved baroque external device (ED).The aqueduct on-off system of the utility model design with, relief tube on-off system is used in conjunction with can be by carrying out pressurising to pressurized water seal, pressurize and pressure release ensure stretching out of pressurized water seal and retract.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Component, position and numbering in figure: aqueduct 1, aqueduct on-off system 2, relief tube 3, relief tube on-off system 4, pressurized water seal 5, inlet flow rate switch 6, rate of discharge switch 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, high pressure gate antipriming of the present utility model, comprise aqueduct 1, aqueduct on-off system 2, relief tube 3, relief tube on-off system 4 and pressurized water seal 5, described aqueduct 1 is connected with pressurized water seal 5, described relief tube 3 is communicated with pressurized water seal 5, aqueduct on-off system 2 is arranged on aqueduct 1, and relief tube on-off system 4 is arranged on relief tube 3.The utility model is directly connected reservoir by aqueduct 1 with pressurized water seal 5, utilize the hydraulic pressure that reservoir self has to carry out pressurising to water seal, the hydraulic pressure of introducing applies certain back pressure to water seal back makes pressurized water seal 5 to the overhanging function that compresses pressurized water seal 5 end sockets and realize sealing of moving, and baroque external device (ED) has been saved in this design of the present utility model.Be arranged on aqueduct on-off system 2 on aqueduct 1 for controlling being communicated with of aqueduct 1 and reservoir, to ensure that pressurized water seal 5 stretches out and aqueduct 1 and reservoir reliable connected when pressurized water seal 5 sealing.The relief tube on-off system 4 being arranged on relief tube 3 can be to carrying out pressure release to pressurized water seal 5 in the time that pressurized water seal 5 need to be retracted.
As shown in Figure 1, described aqueduct on-off system 2 is electric gate valve, and described relief tube on-off system 4 is electric gate valve.Employing electric gate valve can ensure the reliable on off of pipeline, and electric gate valve can be easy to be connected to realize automation control with electrical control system.
As shown in Figure 1, also comprise entrance flow switch 6 and rate of discharge switch 7, described inlet flow rate switch 6 is arranged on aqueduct 1, and described rate of discharge switch 7 is arranged on relief tube 3.Whether inlet flow rate switch 6 for detection of having current to flow to pressurized water seal 5 by aqueduct on-off system 2, and whether rate of discharge switch 7 flows out from pressurized water seal 5 for detection of having current to pass through relief tube on-off system 4.Show that when inlet flow rate switch 6 has stream illustrates that aqueduct on-off system 2 opens when signal, pressurized water seal 5 is communicated with reservoir.When having, rate of discharge switch 7 shows that stream illustrates the air in pressurized water seal 5 and drains when signal, can close relief tube on-off system 4.
