Description

Highway unloads oil gas liquid separation device Technical Field The utility model relates to the technical field of highway oil discharge, in particular to a highway oil discharge gas-liquid separation device. Background The highway oil discharge process of the finished oil depot generally adopts a pipeline centrifugal pump as an oil discharge pump, a pump filling process is needed before the oil discharge operation of the centrifugal pump, a vacuum system or a pressure exhaust (gravity exhaust) method is adopted in the traditional process part, and most of the processes are provided with an oil resistance exhaust valve for exhausting pipeline gas, so that the pump filling effect is realized. The problems existing in the prior art are as follows: The vacuum system has higher manufacturing cost, larger occupied area for the transformation process and complex process. Gravity exhaust or pressure exhaust, which is time-consuming and incomplete, and can not accurately judge whether pump priming (exhaust) is completed. The oil-blocking exhaust valve is characterized in that 1, the exhaust port is blocked by suddenly pilling in the exhaust process, and the exhaust is stopped, and the problems that when the air pressure of a pipeline is high or the air flow is provided with oil products, the large exhaust port is suddenly pilled to stop the exhaust exist in many floating ball type exhaust valves; 2. when the operation is not performed for a long time, the floating ball of the small exhaust port is easy to lose efficacy due to adhesion; 3. in the process of the secondary operation after the oil discharge of the large exhaust port floating ball is finished, the floating ball is easy to run off due to improper reset, and the loss is caused to the maintenance management in the future. Disclosure of utility model The utility model aims to solve the problems that the existing highway oil discharge pump filling process has high manufacturing cost, complex process, incomplete exhaust and incorrect judgment of whether pump filling is finished or not and misoperation risk. In order to achieve the above purpose, the utility model adopts the following technical scheme: The highway oil-gas-liquid separation device is characterized by comprising a first automatic reset valve arranged at the upper end of a filter before a pump of an oil discharge pump and a cylinder body arranged above the filter before the pump, wherein the upper end of the first automatic reset valve is connected with one end of a three-way pipeline, two ends of the three-way pipeline are respectively connected with a second automatic reset valve and a third automatic reset valve, a first viewing cup mirror is connected between the second automatic reset valve and the upper part of the side wall of the cylinder body, a second viewing cup mirror is connected between the third automatic reset valve and the lower end of the cylinder body, the upper end of the cylinder body is connected with an exhaust pipe, a separation silk screen is arranged at the upper part in the cylinder body, and a liquid level meter is arranged on the front surface of the outer wall of the cylinder body. The improvement is that the three-way pipeline is DN15 three-way pipeline. The improvement is that the lower end of the cylinder body is provided with a bracket. It is further improved that the separation silk screen is arranged in the barrel in five places. The further improvement is that the liquid level meter is a glass tube U-shaped liquid level meter. The further improvement is that the first automatic reset valve, the second automatic reset valve and the third automatic reset valve are spring automatic reset valves. The further improvement is that a flowmeter is connected between the oil discharge pump and the pre-pump filter. The further improvement is that the exhaust pipe is provided with an exhaust valve. After the technical scheme is adopted, compared with the prior art, the method has the following beneficial effects: The device has the advantages that the device can effectively exhaust pipeline gas and effectively pump, is simple in structure, convenient to operate, free of automatic equipment in the device, capable of reducing operation termination caused by automatic faults, free of floating balls and other non-fixed parts, and capable of avoiding the failure of sticking of the floating balls, so that the pump can not be pumped on site; the double-hand operation of the exhaust and oil discharge operation reduces the leakage risk caused by misoperation, and the whole process has no open flow operation and reduces the risk.
