Background

According to the requirements of safety and environmental protection, the loading mode of the storage and transportation tank car for hazardous chemicals (oil products and chemical products) is improved from the prior open top loading to the prior closed bottom loading. Before the tank car enters the oil distribution platform and is loaded, the oil gas recovery oil filling riser of the oil loading platform needs to be hermetically connected with an oil gas recovery pipeline on the tank car, namely, an oil gas coupling valve on the oil gas recovery oil filling riser is reliably connected with an oil gas recovery joint on the tank car. And then the dry coupling valve on the liquid phase loading arm is tightly connected with the oil drain valve on the tank car, thereby forming a complete bottom loading loop.

Because the bottom loading belongs to airtight loading, when the inside fluid of liquid phase oil filling riser got into the tank car, the liquid level lifting in the jar compressed the interior oil gas of jar for in jar oil gas passed through the vapor recovery pipeline and got into the vapor recovery system of oil depot. The whole loading process is completely closed, oil and gas cannot be leaked into the air, the environment is effectively protected, and the safety of field loading is greatly improved.

In the operation process, if the oil-gas coupling valve is not reliably connected with an oil-gas recovery joint of the tank car or the oil-gas coupling valve is not smoothly opened, the oil-gas recovery pipeline is not smooth, and the serious consequences of pressure building and explosion in the tank can be caused.

At present, all oil-gas coupling valves used in the field are ordinary non-intelligent oil-gas coupling valves, and do not have the function of intelligently detecting the opening and closing states, so that the risk exists in the field all the time. When manual operation is not in place or the oil-gas coupling valve is disassembled in the middle of aging, the connection is broken, and accidents happen occasionally.

Consequently, for solving unable intellectual detection system of current oil gas coupling valve state, the emergence scheduling problem during the accident, the utility model discloses a detect intelligent oil gas coupling valve of state of opening and shutting.

Detailed Description

To facilitate understanding of the present invention for those skilled in the art, embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides an intelligent oil-gas coupling valve for detecting open-close state, including casing 100, detection device 200 and a plurality of fixing device of setting on casing 100, mount 110, the rubber packing pad 120, end cover 130, valve rod 140, spring 150 of setting in casing 100. The fixing frame 110 is fixedly connected with the inner wall of the shell 100, an oil-gas channel is arranged on the fixing frame 110 to facilitate oil-gas to pass through, a valve rod penetrating channel 111 is arranged at the center of the fixing frame 110, and the rubber sealing gasket 120 is fixed on the fixing frame 110. The sealing end cover 130 is disposed below the fixing frame 110, and a detected magnetic ring 131 is disposed on the sealing end cover 130. The valve stem 140 penetrates through the valve stem penetration passage 111 to be fixedly connected with the sealing end cover 130, one end of the spring 150 is fixedly connected with the inner wall of the valve stem penetration passage 111, and the other end of the spring is fixedly connected with the sealing end cover 130, so that the sealing end cover 130 is tightly attached below the fixing frame 110 in a normal state.
