Description
Technical Field
The invention relates to the technical field of refueling operation, in particular to an emergency treatment method for oil spilling of a well bolt of a plateau pipe network.
Background
The well bolt of the underground pipe network of the apron mainly comprises an oiling bolt bottom valve, a guide valve and a self-sealing oil cavity outlet joint. The principle is that the oil pressure in the apron oil delivery pipe network and the self spring pressure balance principle are utilized to control the opening and closing of the guide valve and the oil cavity, so that the operation of oiling and closing the apron pipe network is realized. When an airplane is refueled, aviation fuel in a apron underground pipe network is input into an airplane fuel tank through a refueling rubber tube and a refueling pump on a pipeline refueling truck, specifically, one end of the refueling rubber tube is provided with a ground well joint for being connected with a ground well bolt, the other end of the refueling rubber tube is connected with a refueling port of the airplane fuel tank, one end of the refueling rubber tube, which is provided with the ground well joint, is required to be moved to the ground well bolt from the refueling truck, the ground well joint is butted with the ground well bolt, the refueling operation can be carried out by opening the ground well bolt, the ground well bolt is closed after the refueling operation is completed, the ground well joint and the ground well bolt are disconnected, and the refueling rubber tube is withdrawn.
In the existing well plug, the isolation valve is opened by pressing down the top plug structure of the pilot valve, and the pilot valve is closed by pulling a pull ring of the pilot valve through external force. Under the non-operation state, the well lid need be covered in order to protect the ground well bolt to the bolt well that ground well bolt place, and the pull ring of guided valve need be accomodate in the bolt well, therefore work direct pulling pull ring need squat down or bow to take out ground well bolt from the bolt well that ground well bolt place and carry out the manual work pulling, and the inconvenient long time that consumes of operation. After normal operation is finished, the guide valve is closed for enough time to operate, but once oil spilling and oil leaking happen, workers need to operate for a long time at a close distance from the oil leaking well bolt, oil is prone to splashing on the workers, and even oil pressure impact or injection into an eye entrance can be caused, so that the workers are injured and poisoned.
The current practice is to use the rope bolt to close the distance that the pilot valve was operated with the extension on the pull ring of pilot valve to make when needing to carry out emergency operation and close the pilot valve, can follow the operation of distant place, avoid the staff to close a long-time operation in oil leak point closely. However, the guide valve is still closed by manual pulling, certain operation time is still needed from the lifting of the rope to the pulling of the force to close the guide valve, and meanwhile, the extended rope can be easily wound on an oil filling rubber pipe or other field devices, so that clamping stagnation occurs when the rope is pulled, and the guide valve cannot be closed from a distance.
Disclosure of Invention
The invention aims to overcome the defects that the operation time for closing a ground well bolt is long, workers need to manually pull a pull ring of a guide valve by strength, and clamping stagnation is easy to occur when the ground well bolt needs to be closed remotely in the prior art, and provides an emergency treatment method for oil spilling of a ground well bolt of a apron pipe network. The traction rope is arranged on the oil filling rubber tube, the length of the traction rope is shortened, the traction rope is prevented from being dragged and abraded on the ground, clamping stagnation caused by the fact that the overlong traction rope is wound on other devices is avoided, meanwhile, the well plug can be closed only by pressing down a switch to start the driving device, operation is simple, and operation time is saved.
The purpose of the invention can be achieved by adopting the following technical scheme:
an oil spill emergency treatment method for a ground well bolt of a plateau pipe network comprises the following steps:
s1: after the refueling rubber tube moves to the position of the well bolt, pulling out one end of a hauling cable from a cable winder arranged at one end of the refueling rubber tube close to the well joint, and bolting one end of the hauling cable to a pull ring on a guide valve of the well bolt;
s2: butting a ground well joint on an oiling rubber pipe with a ground well bolt, and then pressing a bolt inserting mechanism at the top of a pilot valve so as to open the ground well joint for oiling;
s3: if the well plug needs to be closed emergently in the case of oil spilling during the oiling operation, the switch is pressed down to start the rotary driving device, so that the rotary driving device generates acting force on the rope winder to pull the traction rope, and the guide valve is closed;
s4: if the oil spilling condition can not be controlled after the pulling rope is pulled to close the ground well bolt, the connection between the ground well joint and the ground well bolt is disconnected, the connection between the pulling rope and the guide valve or the connection between the rope winder and the oiling rubber tube is released, the oiling rubber tube and the pipeline oiling vehicle are withdrawn from the site, and the closing valve of the apron underground pipe network is closed or the oil supply of the apron underground pipe network is cut off.
According to the invention, the traction rope is arranged on the refueling rubber tube, so that the traction rope moves to the well plug along with the refueling rubber tube, and then the traction rope is pulled out from the refueling rubber tube to be connected with the pull ring on the guide valve. On the haulage rope integration and the refuelling rubber tube, the staff removes the convenience and is difficult to omit and lose the haulage rope when removing to the bolt from the pipeline tank service truck. And because the ground well joint on the refueling rubber tube needs to be butted with the ground well bolt, the distance between the rope winder arranged at one end of the refueling rubber tube close to the ground well joint and the ground well bolt is shorter, so that the length of the traction rope is shorter, and the traction rope is reduced from being abraded or being wound on other devices to cause clamping stagnation when being dragged on the ground. If the emergency such as oil spilling oil leak appears in the in-process of refueling operation, when needing emergency shut-off guide valve, only need starting switch, rotary driving device drive ropewinder produces the pulling force to the haulage rope, make the pull ring of haulage rope pulling guide valve close the guide valve, staff's operation is from the operation of picking up the rope and pulling the rope with strength, reduce into the operation of pressing the switch, staff's reaction time and operating time have so significantly reduced, reduce the volume of revealing of oil, simultaneously still can be for the back no matter withdraw or speedily carry out rescue work all striven for the time. The switch can set up on refueling the rubber tube, also can add remote control module, realizes opening and closing of control rotary drive device on the tank service truck.
The oil spilling condition of the well bolt can be basically divided into different reasons of poor sealing, unreliable connection, overpressure use and the like, the well bolt needs to be closed in an emergency when the oil spilling condition occurs, and the oil spilling and the oil leaking can be prevented after the well bolt is closed under most conditions. And the leakage cannot be prevented after the guide valve of the well bolt is closed, the oil pipe needs to be separated from the connection between the oil filling rubber pipe and the well bolt and an aircraft oil tank, a pipeline refueling truck is arranged to withdraw, and the oil is prevented from leaking oil by closing the isolating valve of part of the oil circuit of the underground pipe network of the apron or cutting off the whole underground pipe network of the apron. And (4) after the reason of oil spilling is checked and the intact state of the well plug facility equipment is confirmed, retesting, and putting into secondary use after the test is qualified. When the connection between the refueling rubber pipe and the ground well bolt is cut off, the refueling rubber pipe connected through the traction rope needs to be cut off from the guide valve except for the connection between the ground well joint and the ground well bolt, the traction rope can be cut off from the pull ring of the guide valve, or the traction rope can be cut off, or the traction rope and the refueling rubber pipe can be cut off, but the cutting-off needs convenient operation.
Further, in step S3, when the rotation driving device drives the pulling rope to pull the pull ring of the pilot valve, the torque sensor identifies the torque output by the rotation driving device and transmits a signal to the control device, and when the control device identifies that the torque output by the rotation driving device exceeds a certain value, it is determined that the pulling force of the pulling rope exceeds the pulling force required for closing the pilot valve, the pilot valve is successfully closed, and the control device controls the rotation driving device to stop.
The torque sensor and the control device are used for limiting the torque output by the rotary driving device, so that the guide valve is prevented from being damaged due to overlarge pulling force of the traction rope, and meanwhile, the traction rope can be ensured to have enough pulling force to close the guide valve.
Further, in the step S1, after the pulling rope is pulled out of the rope winder, the pulling rope extends along the refueling rubber hose until the pulling rope moves to a position close to the refueling joint, and then extends downward to be connected with the pull ring of the pilot valve.
