Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] refer to figure 1 , detailing the implementation process of the oil pipeline valve switch:

[0031] The oil pipeline valve is provided with a valve pipe 11, and the middle part of the valve pipe 11 is provided with a spherical space, and the valve head 21 is rotatably connected in the spherical space in the middle part of the valve pipe 11. When it is coaxial with the valve pipe 11, the two ends of the valve pipe 11 are connected, which can realize the circulation of the maximum flow rate of oil in the valve pipe 11. When the flow hole on the valve head 21 is perpendicular to the axis of the valve pipe 11, the valve pipe Both sides of 11 are completely blocked by the valve head 21 to realize the disconnection of the pipes at both ends of the valve pipe 11, and the sealing member slides inside the valve pipe 11 and the valve head 21. When the center i...

Abstract

The invention relates to the field of petroleum valves, in particular to a petroleum pipeline valve. The petroleum pipeline valve has the advantage of emergency closing when the valve breaks down and comprises a valve pipe, a valve head and a plugging piece, the valve head is rotatably connected to the valve pipe, the plugging piece is slidably connected to the valve pipe and the valve head, and a circulation hole is formed in the valve head. The petroleum pipeline valve further comprises a spherical bin, the spherical bin is arranged on the valve pipe, and the valve head is rotationally connected into the spherical bin. The petroleum pipeline valve further comprises a plugging piece, a plugging groove and a blind hole, the plugging groove and the blind hole are formed in the middle of the valve head, the axis of the blind hole is perpendicular to the axis of the circulation hole in the valve head, and the plugging piece is connected into the plugging groove and the blind hole in a sliding mode.

Description

technical field [0001] The invention relates to the field of petroleum valves, in particular to a petroleum pipeline valve. Background technique [0002] Control valves are widely used to control the process parameters of gas, liquid, steam and other media such as pressure, flow, temperature, and liquid level to maintain a given value. At present, in modern control, the regulating valve plays a very important role. Whether the regulating valve can work normally directly affects the use effect of the entire pipeline control system. [0003] Patent No. 111795163A discloses an anti-blocking regulating valve, including a valve body, a valve cavity is arranged in the valve body, a valve plate is arranged in the valve cavity, and the valve cavity is divided into an upper valve cavity by the valve plate. and the lower valve chamber, the valve plate is provided with a valve port, and the valve plate is provided with an orifice at the upper end of the valve port; the side of the val...
