Abstract

The utility model relates to a leakage stopping device with oil and pressure for a crude oil conveying pipe line. The utility model is capable of effectively stopping leak points of a piping accessory on a pipe line. The utility model comprises a tension screw rod 3, screw stoppers 8, an open pore valve 9, a drainage flexible tube 11, a hermetic open pore device 12, etc., wherein, the side part of a tube 4 is provided with the tension screw rod 3, and the middle of the top part of the tube 4 is provided with an open pore short joint 6; the screw stopper 8, a screw stopper cap 7, the drainage flexible tube 11, a quick connecting head 10, the open pore valve 9 and the screw stopper 8 which are arranged in the open pore short joint 6 are successively connected. Due to the function of the drainage, even if the pressure of a trunk line is well above 0.5 MPa, the leakage stopping device has better function of leakage stopping with oil and pressure provided the flow of the leak points is not greater than the flow of the drainage, namely, the internal pressure of the leakage stopping device is not greater than 0.2 MPa. The utility model which is especially suitable for stopping the leakage of an oil conveying pipe line with leak points on an accessory can shorten first-aid repairing time and ensure that the pipe line is clear.

Description

Oil pressure leak stopping device
The utility model relates to the effectively oil pressure leak stopping device of piping attachment place leak source on the shutoff pipeline of a kind of oil transmission line.
At present, used leak stopping device, piping attachment (valve, pipe nipple etc.) is arranged when locating the repairing of leakage of oil on to oil transport pipeline, by the time after the oil transport pipeline stopping transportation, piping attachment place leak source is oil-proof, just can carry out the shutoff soldering, and this just makes owing to reasons such as oil transport pipeline potential difference cause the more than or leakage of oil overlong time of leakage of oil, can not in time repair, in time resume production.
The purpose of this utility model is to provide a kind of timely oil pressure shutoff leak source when in petroleum pipeline certain pressure being arranged, and promptly and rapidly recovers the oil pressure leak stopping device that oil transportation is produced.
The utility model is achieved in that and includes tight riding chain bar 1, welded plate 2, tight power leading screw 3, pipe 4, end socket 5, perforate pipe nipple 6, plug cap 7, plug 8, perforate valve 9, rapid pipe joint 10, drainage flexible pipe 11, airtight trepanning device 12, tight riding chain bar 1 is arranged in the bottom of pipe 4, the sidepiece of pipe 4 has tight power leading screw 3, welded plate 2 respectively with pipe 4, tight power leading screw 3 connects, end socket 5 is arranged at the top of pipe 4, the crown center of pipe 4 has perforate pipe nipple 6, perforate pipe nipple 6 inner screw plugs 8, plug cap 7, drainage flexible pipe 11, rapid pipe joint 10, perforate valve 9, plug 8 connects successively.
The utility model also adopts following technological scheme:
Perforate pipe nipple 6 is welded in the top of end socket 5.
2 of pipe 4 and welded plates have Stamping Steel Ribbon 13.
Tight riding chain bar 1 can be a chain, also can be wire rope.
Plug 8 is communicated with airtight trepanning device 12.
The length of drainage flexible pipe 11 is greater than 10 meters.
Advantage of the present utility model is: when bearing pressure in leak stopping device chamber, sealing part is non-leakage, and the whole pressure capability of bearing increases, because the effect of drainage, even the pressure of main line is higher than 0.5Mpa, as long as the leak source flow is not more than the drainage flow, promptly leak stopping device internal pressure is not more than 0.2Mpa, and plugging device all has the effect of oil pressure leak stopping preferably, this device has the leak stopping of annex leak source to petroleum pipeline, especially suitable, can shorten the repairing time widely, guarantee that petroleum pipeline is unimpeded.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the flourishing schematic representation of Stamping Steel Ribbon.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, end socket 5, perforate pipe nipple 6 have constituted the leak stopping end socket, and its main effect is that the accessories cover of leakage of oil is carried out shutoff in leak stopping end socket the inside.
As shown in Figure 2: Stamping Steel Ribbon 13 is made up of saddle type seal groove and O type Stamping Steel Ribbon, and its effect is a sealing leakage of oil face.
Welded plate 2 is heat insulation, it is an arc plate, its end is after Stamping Steel Ribbon is compressed, be not more than 3mm with the gap of pipeline surface, be convenient to welding, its main effect is that the heat that the welding of leak stopping end socket and pipeline produces is deflected from Stamping Steel Ribbon, prevents to burn out Stamping Steel Ribbon and produces leakage of oil, reaches the purpose of oil pressure leak stopping with this.
Tight power leading screw 3, tight riding chain bar 1 have been formed tight force mechanisms, and its effect is exactly that effect by tight power is attached to the seal arrangement of leak stopping end socket on the pipeline firmly, prevents leakage of oil.
Perforate pipe nipple 6, perforate valve 9, drainage flexible pipe 11 have been formed drainage mechanism, and its effect is draining into place of safety with leaking into crude oil normal pressure in the leak stopping end socket chamber, be convenient to the welding procedure of end socket, and the length of drainage flexible pipe 11 is more preferably greater than 10 meters.
Airtight trepanning device 12, plug 8 have been formed airtight down plug mechanism, its effect be exactly after the end socket welding is finished plug 8 times in pipe nipple 6, to reach the purpose of shutoff.
During use, the leak stopping device of the drainage flexible pipe 11 that installs in advance is buckled on the leak source, promptly tighten tight power leading screw 3, make the leak stopping device be attached on the pipe firmly, because the seal action of Stamping Steel Ribbon, the leakage of oil that leak source is produced is guided to apart from the following 10 meters places far away of wind direction of leakage of oil point by perforate valve 9 and drainage flexible pipe 11, and clear up the sump oil at leak source scene rapidly, make it to possess the condition of getting angry, after affirmation can be got angry, be welded on welded plate 2 on the petroleum pipeline securely immediately, and accomplish fluently various stiffening plates, close perforate valve 9 and pull down drainage flexible pipe 11, and rapid first-class band plug 8 airtight trepanning devices 12, following good plug 8, pull down perforate valve 9, first-class plug cap 7 is welded on plug cap 7 on the perforate pipe nipple 6, and the overall process of entire belt oil leak stopping just is through with like this.
