Description
Technical Field
The utility model relates to a pipeline mouth gag, concretely relates to area is pressed mouth gag suitable for pipeline installs the gate valve additional.
Background
The valve is an indispensable device in industrial production, the gate valve is one of various types of valves, the opening and closing member of the gate valve is a gate plate, the moving direction of the gate plate is perpendicular to the fluid direction, and the gate valve can only be fully opened and fully closed and cannot be used for controlling the flow.
In actual production, the situation that a new pipeline is used for enlarging the production scale on the basis of an original pipeline is rare, a gate valve is usually additionally arranged at the inlet end of the newly arranged pipeline to realize full opening and full closing of the pipeline, the existing mode is to stop the original pipeline and then butt joint the new pipeline and the original pipeline, but stopping the operation of fluid in the original pipeline inevitably delays the existing production, and certain important equipment is stopped and restarted to cause great loss.
Therefore, there is a need in the art for a new technical solution that can open and install a gate valve on an original pipeline under pressure without stopping the operation of the original pipeline.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a mouth gag is pressed in area suitable for pipeline installs the gate valve additional can install the gate valve additional on original pipeline on the basis that does not stop original pipeline to extend out new branch on original pipeline.
An under-pressure mouth gag suitable for additionally installing a gate valve on a pipeline comprises a flange connection body, wherein at least two bearings are fixed inside the flange connection body through snap springs, a driving rod is connected in the bearings in a sliding manner, a saw blade is fixedly connected to the front end of the driving rod, and the rear end of the driving rod is connected with a driving device;
still be provided with the sealing ring in the flange joint body, the fixed one end that keeps away from the saw bit that sets up in the flange joint body of sealing ring, sealing ring and actuating lever sliding connection.
Further, the bearing has a seal cover.
Furthermore, a sealing ring line is arranged on the end face of one side, close to the saw blade, of the flange connection body.
Further, the driving device includes an electric motor and a hydraulic motor.
Adopt above-mentioned technical scheme the utility model discloses following beneficial effect can be brought:
the utility model discloses can install the gate valve additional and take the pressure opening operation on original pipeline under the prerequisite that does not stop original pipeline operation, greatly reduce the loss because of original pipeline outage brings.
Drawings
Fig. 1 is a schematic structural diagram of the present invention (driving device is not shown).
In the figure, 1-flange connection body, 2-driving rod, 3-saw blade and 4-sealing ring line.
Detailed Description
As shown in figure 1, the pressurized mouth gag suitable for the pipeline additionally provided with the gate valve is characterized in that: the pipeline cutting device comprises a flange connecting body 1, wherein the flange connecting body 1 is connected with a gate valve, at least two bearings are fixed in the flange connecting body 1 through clamp springs, a driving rod 2 is connected in the bearings in a sliding mode, a saw blade 3 is fixedly connected to the front end of the driving rod 2, the rear end of the driving rod is connected with a driving device, and actually, a layer of strong magnetic material is preferably arranged at the bottom of the saw blade 3 to ensure that the part sawn from the original pipeline is adsorbed on the saw blade;
still be provided with the sealing ring in the flange joint body 1, the sealing ring is used for preventing the medium in the pipeline from spouting in the flange joint body 1, the sealing ring is fixed to be set up in the one end that the saw bit 3 was kept away from to flange joint body 1, sealing ring and actuating lever 2 sliding connection.
The bearing is provided with a sealing cover, and debris is prevented from entering the bearing to cause damage to the bearing.
The end face of the flange connecting body 1, which is close to one side of the saw blade 3, is provided with a sealing ring line 4, and the sealing ring line 4 enables the flange connecting body 1 to be more tightly connected with the gate valve, so that the medium is further prevented from flowing out of the flange connecting body and the gate valve.
Further, the driving device includes, but is not limited to, an electric motor and a hydraulic motor, and the suitable driving device can be selected according to actual conditions in the field.
For safety, require in principle the utility model discloses the medium pressure in the former pipeline of operation does not exceed eight megapascals, and the pipeline pressure does not suggest to use under the condition that exceeds eight megapascals the utility model discloses carry out the opening operation.
The following brief description of the utility model discloses a work flow:
use the utility model discloses before, at first will weld one section shorter pipeline on original pipeline, then keep away from the one end of original pipeline on this shorter pipeline and install the gate valve additional, later set the gate valve to the state of full open, will again the utility model discloses pass through bolted connection fixed back with the gate valve, start drive arrangement and exert pressure to actuating lever 2 for carry out the opening operation to original pipeline after saw bit 3 passes gate valve and shorter pipeline, pull back the normal position with actuating lever 2 after the opening finishes and close the gate valve, pull down the utility model discloses, later carry out the butt joint of subsequent lateral conduit and gate valve.
