Abstract
The utility model discloses a high -low pressure pipeline drilling fluid emptying devices, including the pin thread thread protector, the handle be connected with the pin thread thread protector, the top of pin thread thread protector connect tee junction spare, conduct is lost heart mouthful in two relative ports of tee junction spare, in two relative ports of tee junction spare another is connected with the pin thread thread protector, the air inlet is connected to a third port of tee junction spare, and the air inlet is connected with high -pressure gas -supply pipe, and a mouthful run -on air traffic control loses heart. The utility model discloses a department sets up tee junction spare at the pin thread thread protector, after dismantling the kelly, directly cup joints the connection to this device pin thread thread protector on the kelly pin thread, with gas motor pipeline connection to air inlet, open the gate of high -low pressure pipeline after, open compressed air, the drilling fluid of drain on -line. After having arranged the interior drilling fluid of pipeline, kelly and trachea on -line have the incomplete existing gas body, when unloading the trachea line, spout outward through the orad that loses heart, are convenient for improve the efficiency of operation to the disassembling operation of air inlet department.
Description
Technical field
This utility model relates to emptier, is exactly a kind of high-low pressure pipeline drilling fluid emptier.
Background technology
Winter construction, owing to temperature is low, high pressure line easily freezes, and the way generally used is that kelly bar unloads after drawing in rat hole, and rotary hose is pounded, and ejects the drilling fluid in pipeline by compressed air, is then shut off standpipe gate.This way needs rigger to climb up faucet, and rotary hose is pounded down, under get into the end before connect again, troublesome；It addition, worn in winter medicated clothing is thicker, climb up climb down dangerous；Also can because of the surplus drilling fluid of rotary hose spread everywhere, not environmentally.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of high-low pressure pipeline drilling fluid emptier, and this apparatus structure is simple, it is possible to avoids attendant and climbs the danger of faucet, improves working performance.
For solving above-mentioned technical problem, this utility model following technological means of employing:
A kind of high-low pressure pipeline drilling fluid emptier, including pin thread thread protector, the handle being connected with pin thread thread protector, the top connecting tee connector of described pin thread thread protector, three-way connector is connected with pin thread thread protector relative to another in two ports as leakage port, three-way connector relative in two ports one；3rd port of three-way connector connects air inlet, and air inlet is connected with high pressure gas pipeline, and leakage port connects evacuated tube.
This utility model is by arranging three-way connector at pin thread thread protector, after dismantling kelly bar, this device pin thread thread protector is directly socketed and is connected on kelly bar pin thread, it is connected to air inlet by gas motor line, after opening the gate of high-low pressure pipeline, open compressed air, get rid of the drilling fluid in pipeline.In drained pipeline after drilling fluid, in kelly bar and gas pipeline, there is survival gas, when unloading gas pipeline, outwards sprayed by leakage port, it is simple to the disassembling section at air inlet, improve the efficiency of operation.
Further optimal technical scheme is as follows:
Control valve it is provided with at described leakage port.By arranging control valve, it is possible to use leakage port is opened or closes by valve, it is beneficial to the adjustment of the duty of this device.Above-mentioned valve is long operation handle valve, and the valve of long operation handle can facilitate the operation opened, close of valve.
Being arranged with connecting hole on described pin thread thread protector, connecting hole is connected with handle threads.By above-mentioned setting, handle is easier to be connected with pin thread thread protector or dismantle, to facilitate the assembling of this device to use.
The handheld terminal of described handle is provided with branch sleeve；Branch sleeve is threadeded with the handheld terminal of handle.By arranging branch sleeve, when needing bigger power to rotate this device, branch sleeve can be connected to the handheld terminal of handle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: 1. air inlet；2. pin thread thread protector；3. handle；4. leakage port.
Detailed description of the invention
Below in conjunction with embodiment, further illustrate this utility model.
See Fig. 1 to understand, a kind of high-low pressure pipeline drilling fluid emptier of the present utility model, by pin thread thread protector 2, the handle composition being connected with pin thread thread protector 2, the top connecting tee connector of described pin thread thread protector 2, three-way connector is connected with pin thread thread protector 2 relative to another in two ports as leakage port 4, three-way connector relative in two ports one；3rd port of three-way connector connects air inlet 1, and air inlet 1 is connected with high pressure gas pipeline, and leakage port 4 connects evacuated tube.
It is provided with control valve at described leakage port 4.By arranging control valve, it is possible to use leakage port 4 is opened or closed by valve, it is beneficial to the adjustment of the duty of this device.Above-mentioned valve is long operation handle valve, and the valve of long operation handle can facilitate the operation opened, close of valve.
Being arranged with connecting hole on described pin thread thread protector 2, connecting hole is connected with handle threads.By above-mentioned setting, handle 4 is easier to be connected with pin thread thread protector 2 or dismantle, to facilitate the assembling of this device to use.
The handheld terminal of described handle 4 is provided with branch sleeve；Branch sleeve is threadeded with the handheld terminal of handle 4.By arranging branch sleeve, when needing bigger power to rotate this device, branch sleeve can be connected to the handheld terminal of handle.
This utility model is by arranging three-way connector at pin thread thread protector 2, after dismantling kelly bar, this device pin thread thread protector 2 is directly socketed and is connected on kelly bar pin thread, it is connected to air inlet 1 by gas motor line, after opening the gate of high-low pressure pipeline, open compressed air, get rid of the drilling fluid in pipeline.In drained pipeline after drilling fluid, in kelly bar and gas pipeline, there is survival gas, when unloading gas pipeline, outwards sprayed by leakage port 4, it is simple to the disassembling section at air inlet 1, improve the efficiency of operation.
Owing to the foregoing is only detailed description of the invention of the present utility model; but protection of the present utility model is not limited to this; any those skilled in the art it is contemplated that the change of equivalent of the technical program technical characteristic or replacement, all contain within protection domain of the present utility model.
