Description
Technical Field
The utility model relates to an oil field well head device accessory technical field, concretely relates to flange formula tee bend end ware.
Background
At present, the cut-off valve connected on the oil field metering room or gathering process flow pipeline mostly adopts a national standard ball valve or a national standard cut-off valve, has large consumption, and has the characteristics of more impurities and strong corrosivity because the medium transported by the oil field is mostly two-phase or three-phase mixed liquid of crude oil, natural gas, water and the like. Due to the reasons, the service life of the valve is short, and the valve is frequently maintained and replaced. The existing block valve has the disadvantages that a valve shell and flange sheets at two ends are integrated, and two ends of a connected gathering and transportation pipeline are elastically fixed, so that when the valve is installed or disassembled and replaced, a special tool is needed to open a certain gap for the flange on the pipeline to install or disassemble the valve, the operation is time-consuming and labor-consuming, and the normal production progress is often delayed. Because a large number of pipeline valves exist in an oil field, and a plurality of blocks are located in remote areas, the installation or replacement of the valves once takes a long time, and the labor efficiency is low; the other disadvantage is that the common pipeline valve has a sealing problem and needs to be integrally replaced, the disassembled valve is scrapped, and the durable parts such as the shell and the like are scrapped, thereby wasting financial resources.
Disclosure of Invention
The utility model aims at providing a flange type three-way stop, which aims at solving two existing problems of valves in oil field production and maintenance, one of which is to solve the problems of large difficulty in valve installation and replacement and more tools to be carried; and secondly, the problem of large waste of valve replacement is solved.
The utility model discloses a flange formula tee bend end device comprises adjusting flange, casing and control valve, the outer wall of casing one end be equipped with the screw thread, adjusting flange is connected with the casing through the screw thread, the other end of casing is equipped with mounting flange, the inside of casing is equipped with the valve casing, feed liquor passageway and liquid outlet channel two parts are separated into with the casing to the valve casing, the lower part of valve casing is equipped with interface channel, interface channel is between 30 ~ 60 with feed liquor passageway's central line contained angle, interface channel is linked together with feed liquor passageway and liquid outlet channel respectively, the inside of valve casing is equipped with the control valve, the control valve is located interface channel's below.
As a further improvement of the utility model, the inlet and the liquid outlet mutually perpendicular of the connecting channel.
As a further improvement of the utility model, the control valve is a stop valve core body or a ball valve core body.
Adopt above-mentioned technical scheme's positive effect: the utility model discloses simple structure directly uses on the gathering line, and it is more convenient that whole change valve or maintenance stop valve core body do not need to use specialized tool, practices thrift maintenance, replacement cost, reduces maintenance, change time, makes things convenient for oil field production.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the assembly structure of the present invention;
FIG. 3 is an enlarged view of portion A of FIG. 2;
fig. 4 is a schematic view of the structure in the state where part a is connected.
In the figure: 1 adjusting flange, 2 casing, 3 control valve, 4 liquid inlet channel, 5 connecting channel, 6 liquid outlet channel, 7 fixing flange, 8 valve casing, matching flange 9 and sealing gasket 10.
The specific implementation mode is as follows:
the utility model discloses a flange type three-way stop, which comprises an adjusting flange 1, a shell 2 and a control valve 3, wherein the outer wall of one end of the shell 2 is provided with screw threads, the inner hole of the adjusting flange 1 is provided with screw threads, and the adjusting flange 1 is connected with the shell 2 through the screw threads; meanwhile, the outer end of the adjusting flange 1 is provided with a sealing section which is used for being matched with a matching flange 9 on the pipeline to play a role in sealing; the distance between the adjusting flange 1 and the shell 2 can be adjusted by rotating the adjusting flange 1, and sealing is ensured; the other end of the shell 2 is provided with a fixed flange 7, the positions of the fixed flange 7 and the adjustable flange 1 can be interchanged, and the adjustable flange 1 can be adopted at both ends; a valve casing 8 is arranged in the casing 2, the casing 2 is divided into a liquid inlet channel 4 and a liquid outlet channel 6 by the valve casing 8, a connecting channel 5 is arranged at the lower part of the valve casing 8, the angle between the central line of the liquid inlet channel 4 and the central line of the connecting channel 5 can be within a given range, the left side of the connecting channel 5 is communicated with the liquid inlet channel 4, the right side of the connecting channel 5 is communicated with the liquid outlet channel 6, and a liquid inlet and a liquid outlet of the connecting channel 5 are mutually vertical (as shown in figure 1); the control valve 3 is arranged in the valve casing 8, the control valve 3 is a stop valve core body or a ball valve core body, the control valve 3 is a non-national standard product widely applied in Daqing oil field areas, such as a KNZ-01 type built-in valve core, and the control valve can be used as long as the function can be achieved, and is not specially limited; the control valve 3 is positioned below the connecting channel 5, and the ascending and descending of the valve heads on the control valve 3 determine the opening and closing of the connecting channel 5.
The adjusting flange 1 is connected with the shell 2 through screw threads and sealed through an O-shaped sealing ring, and the adjusting flange has the effects that when the adjusting flange is mounted and dismounted, the adjusting flange 1 can be rotated to adjust the gap between the flange type three-way stop and the pipeline matching flange 9, and the overlapping degree of the bolt holes in the rotating flange and the center lines of the bolt holes in the pipeline matching flange can be adjusted.
As shown in figure 2, when the adjusting flange 1 on the flange type three-way cut-off device is used, the adjusting flange 1 on the flange type three-way cut-off device is firstly screwed to the position with the minimum distance on a shell, then one side of the shell 2 with the fixing flange 7 is connected with a matching flange 9 on a pipeline through bolts, after the connection is completed, the adjusting flange 1 is rotated towards the outer side of the shell 2 until the adjusting flange is contacted with a sealing gasket 10 of the matching flange 9 on the other side of the pipeline, and then the adjusting flange is screwed up through bolts.
The utility model discloses simple structure directly uses on the ground technology pipeline or between the measurement, and it is more convenient to change flange formula tee bend end ware, does not need extra assembly and disassembly tools, does not need the whole change when changing the control valve, makes things convenient for oil field production.
