Abstract
The utility model relates to a constant-pressure sleeving-placing device applied to an oil field steam delivery pipeline. The technical scheme is that an upper-portion sleeve is connected and fixed with a lower-portion connector, one side of the lower-portion connector is provided with a steam medium inlet, a sealing seat is installed at the upper end, a through hole is formed in the center of the sealing seat, and the sealing seat and the upper-portion sleeve are communicated through the through hole. A central sealing rod is installed at the upper portion of the sealing seat and consists of a sealing head at the bottom and a central rod at the top, the sealing head is in matched connection with the through hole of the sealing seat, and the central rod is connected with a guide cap at the top of the upper-portion sleeve. A weighting block is installed on the central sealing rod, and the central sealing rod is pressed on the sealing seat through gravity. The constant-pressure sleeving-placing device has the advantages that the satiations of manual inspection and judgment and manual valve opening/closing in an existing pipeline conveying system are improved, the purpose of adjusting the opened/closed valve is achieved by increasing and decreasing the weighting block, and the problem that an adopted remote control system is high in cost is avoided.
Description
Technical field
The utility model relates to a kind of oil field steam pipeline duct device, and particularly a kind of level pressure cover is put device.
Background technique
Now in steam conveying pipeline, because delivery line is longer, the loss of course of conveying or have leak source, easily cause the vapor pressure of carrying not reach usage requirement, the equipment that affects normally moves, in order to address this problem, conventionally adopt lower-cost pressure gauge to detect, professional is responsible for inspection unlatching or throttle down, and Remote Automatic Control System, because cost is higher, seldom uses.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provide a kind of level pressure cover to put device, solve in existing pipeline transport system, by manually checking, judging, the present situation of manually opened/throttle down, according to different pressure increase and decrease weights, utilize deadweight, reach the object that regulates On/Off valve.
Its technological scheme is: comprise bottom joint, sealing seat, central seal bar, upper sleeve, guiding cap, weight, described upper sleeve and bottom joint are connected and fixed, one side of described bottom joint is provided with steam medium entrance, sealing seat is installed in upper end, the center of described sealing seat is provided with through hole, by through hole, sealing seat is communicated with upper sleeve; The top mounting center seal bar of sealing seat, central seal bar is connected to form by the sealing head of bottom and the center-pole at top, and described sealing head and the through hole of sealing seat are connected, and center-pole is connected with the guiding cap at upper sleeve top; Weight is arranged on central seal bar, by gravity, central seal bar is pressed on sealing seat.
The top bump of above-mentioned guiding cap is also pressed on the outer wall of upper sleeve, and the lower central of guiding cap is provided with guiding groove, and insert in guiding groove the upper end of center-pole.
Between above-mentioned sealing head and center-pole, be provided with supporting base, described weight is arranged on supporting base, and center-pole is inserted in the center hole of weight.
The beneficial effects of the utility model are: improve in existing pipeline transport system, by manually checking, judging, the present situation of manually opened/throttle down, in this device, increase and decrease weight according to different pressure, utilize the deadweight of weight, reach the object that regulates On/Off valve, also avoided employing tele-control system, the problem that its cost is higher.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is sealing seats of the present utility model and the figure that coordinates of central seal bar;
Accompanying drawing 3 is structural drawing of weight of the present utility model;
In upper figure: bottom joint 1, sealing seat 2, central seal bar 3, upper sleeve 4, guiding cap 5, weight 6; Through hole 2.1, sealing head 3.1, center-pole 3.2, supporting base 3.3, center hole 6.1.
Embodiment
1-3 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises bottom joint 1, sealing seat 2, central seal bar 3, upper sleeve 4, guiding cap 5, weight 6, described upper sleeve 4 is connected and fixed with bottom joint 1, one side of described bottom joint 1 is provided with steam medium entrance, sealing seat 2 is installed in upper end, the center of described sealing seat 2 is provided with through hole 2.1, by through hole 2.1, sealing seat 2 is communicated with upper sleeve 4; The top mounting center seal bar 3 of sealing seat 2, central seal bar 3 is connected to form by the sealing head 3.1 of bottom and the center-pole 3.2 at top, described sealing head 3.1 is connected with the through hole 2.1 of sealing seat 2, and center-pole 3.2 is connected with the guiding cap 5 at upper sleeve 4 tops; Weight 6 is arranged on central seal bar 3, by gravity, central seal bar 3 is pressed on sealing seat 2.
Wherein, the top bump of guiding cap 5 is also pressed on the outer wall of upper sleeve 4, and the lower central of guiding cap 5 is provided with guiding groove, and insert in guiding groove the upper end of center-pole 3.2.
In addition, between sealing head 3.1 and center-pole 3.2, be provided with supporting base 3.3, described weight 6 is arranged on supporting base 3.3, and center-pole 3.2 is inserted in the center hole 6.1 of weight 6.
Steam medium is entered by bottom joint 1, is not reaching under working pressure condition, and weight 6 is pressed on central seal bar 3 under Action of Gravity Field, seal bar bottom and sealing seat 2 are closed state, now, this device is air-tight state, and steam medium can not pass through sealing seat 2; In the time that pressure progressively reaches usage requirement, steam is greater than weight deadweight applied pressure at the interior pressure to sealing seat hole of bottom joint 1, make the direction lifting of central seal bar 3 along guiding cap 5, seal bar bottom and sealing seat 2 are opening state, now, this device is circulation status, the flow process that makes steam medium enter back through upper sleeve.
