Abstract
The utility model discloses a pressurized drilling work joint for a gas pipe, which aims to provide a pressurized drilling work joint for a gas pipe with the advantages of compact structure, less maintenance expenses, less investment and high safety performance. A connecting pipe of the joint is fixedly connected with a user pipe in a T shape; a groove is arranged on the inner wall at the upper part of the connecting pipe; a sealing plate is arranged in the groove; a positioning screw is arranged at the upper end of the sealing plate; an O-shaped sealing ring is arranged between the sealing plate and the groove on the inner wall of the connecting pipe. The pressurized drilling work joint for a gas pipe of the utility model is used for being connected with a gas main pipe at the time of pressurized drilling work. Because a gate valve is omitted, the construction investment of pipe network can be reduced. A gate well can not be bricked, and the utility model has the advantages of less maintenance expenses, less leakage points, high safety performance, low cost of pressurized drilling work and compact structure. The utility model is more suitable for the situation of the burying depth of the existing main pipe relative to other adjacent pipelines, and is convenient for the pressurized drilling work.
Description
Technical field
The utility model relates to a kind of joint, in particular, relates to a kind of gas pipeline band that is applicable to and presses the joint of bore operation.
Background technique
At present, when existing gas pipeline band presses bore operation user pipe to be connected with main pipe, adopt the first end of flange short circuit to be connected with main pipe, the other end is connected with gate valve, and the other end of gate valve connects user's pipe again.This Placement complex structure, the relative buried depth of main pipe of operation is shallow now, closely waits the enforcement that has restricted band pressure bore operation with other pipeline distance of vicinity.And need build the lock well in the joint, and increased the expense of maintaining, also increased a leak point simultaneously, there is potential safety hazard.And lock well and main pipe are too near, are not easy to maintenance.The relative buried depth of main pipe of operation is shallow now, and existing connection request main pipe buried depth is dark, therefore, the main pipe of existing certain areas can not adapt to the existing needs that connect air feed, some users can not be connected with main pipe, thereby can not air feed, make troubles for people's life.And gate valve all need be used in each joint, and the pipeline network construction investment is big.
The model utility content
The purpose of this utility model is, a kind of compact structure is provided, and the maintaining expense is little, little investment, and the gas pipeline band that Safety performance is high is pressed the bore operation joint.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of gas pipeline band is pressed the bore operation joint, it is characterized in that, connecting tube and user's pipe are fixedly connected into " " type, described connecting tube upper inside wall is provided with groove, be provided with sealing plate in the described groove, described sealing plate upper end is provided with positioning screwn, and described sealing plate is provided with the O RunddichtringO with between the connecting tube inboard wall groove.
Described O RunddichtringO is fixed in the ring groove on the sealing plate circumference, described sealing plate, is drive fit between O RunddichtringO and the connecting tube.
The end of described connecting tube is connected with flange, and described flange is connected with the end cap that is positioned at the connecting tube end by bolt, is provided with the O RunddichtringO between described flange and the end cap.
Described sealing plate be provided with push rod device on leading screw and the corresponding blind hole of feed rod.
Gas pipeline band of the present utility model presses the bore operation joint to have following advantage:
1. use gas pipeline band of the present utility model to press the bore operation joint to omit gate valve, reduced the investment of pipeline network construction.
2. can build the lock well, reduce the expense of safeguarding maintenance, reduce the leak point, Safety performance improves, and has lowered the cost of band pressure bore operation.
3. gas pipeline band of the present utility model is pressed bore operation joint structure compactness, more can adapt to the near situation of shallow and contiguous other pipeline of the relative buried depth in existing principal road, and convenient band is pressed bore operation.
Description of drawings
Fig. 1 is the schematic representation that the utility model gas pipeline band is pressed the bore operation joint;
Fig. 2 is the schematic representation that the utility model gas pipeline band is pressed bore operation joint installation exercise.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
The schematic representation of the utility model gas pipeline band pressure bore operation joint as shown in Figure 1, connecting tube 1 and user manage 10 and adopt welding manner to be fixedly connected into " " type, the connecting tube upper inside wall is provided with groove, is fixed with sealing plate 2 in the groove, and the sealing plate upper end is provided with positioning screwn 9.Sealing plate is with being provided with O RunddichtringO 4 between the inboard wall groove on the connecting tube.The quantity of positioning screwn is 4.In order to prevent the pipeline leakage, be connected with flange 8 in the end of connecting tube, flange is connected with the end cap 5 that is positioned at the connecting tube end by bolt 7, is provided with O RunddichtringO 6 between flange 8 and the end cap 5.
Operation for convenience, O RunddichtringO are fixed in the ring groove on the sealing plate circumference, sealing plate, are drive fit between O RunddichtringO and the connecting tube.In order to improve sealing effect, use 2 O RunddichtringOs.
For easy to operate, use push rod device that sealing plate is located, therefore sealing plate be provided with push rod device on leading screw 13 and feed rod 14 corresponding blind holes 3.
The schematic representation that the utility model gas pipeline band is pressed bore operation joint installation exercise before the operation, will have earlier that corresponding blind hole 3 is connected standby with the feed rod 14 of push rod device with leading screw 13 on the sealing plate 2 of O RunddichtringO as shown in Figure 2.Press connecting tube part one end of bore operation joint to be welded on the combustion gas main pipe 16 on gas pipeline band of the present utility model, again user's tubular portion and user are managed welding well.Suppress qualified after, special-purpose gate valve 11 1 ends of holing are connected with the other end of connecting tube by flange 8, the other end of gate valve is connected with driling machine.After boring is finished, close gate valve and pull down rig.Have O RunddichtringO and sealing plate end cap group 12 and the gate valve 11 of push rod device be connected by flange, flange is with the sealing of combustion gas oil-resistant rubber insert.Gate valve is all opened, and shakes crank 15 drive leading screws and sealing plate is shifted onto in the groove of connecting tube inwall, positioning screwn is tightened and welded dead.Pull down push rod device and gate valve.Pressing end cap gets final product.
Although relate to a kind of gas pipeline band and press the bore operation joint to carry out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
