Embodiment
[0026] Example: see Figure 1-Figure 4 , wherein, a pipeline throttle valve includes a valve body 1 , a liquid inlet pipe 2 , a liquid outlet pipe 3 and a throttle pipe 4 . The liquid inlet pipe 2 is fixedly mounted on one side of the valve body 1, the liquid outlet pipe 3 is fixedly mounted on the other side of the valve body 1, the throttle pipe 4 is fixedly embedded in the middle of the top of the valve body 1, and the valve body 1. A valve stem 5 is inserted through and installed inside. A throttling mechanism 6 is embedded in the inner wall of the throttle tube 4 close to the valve stem 5 . A connection mechanism 7 is installed at the outer bottom of the valve stem 5, a feedback mechanism 8 is embedded in the liquid inlet pipe 2 and the liquid outlet pipe 3, and the throttling mechanism 6 includes an adjusting screw 601, a fixed tooth plate 602, a movable clamp arm 603, a rotating tooth Ring 604 , telescopic tooth plate 605 , brake pad 606 and cutoff plate 607 . The cu...

The invention belongs to the technical field of petroleum pipeline transportation and discloses a pipeline throttling valve. It includes a valve body and a throttle tube, the throttle tube is fixedly embedded and installed in the middle of the outer top end of the valve body, the flow divider is evenly socketed and installed at the outer bottom edge of the valve stem, and the fixed teeth The disk is sleeved and mounted on the top of the valve stem, the movable clip arm is rotatably mounted on both sides of the fixed toothed disk, and the rotating gear ring is welded and mounted on the top of the movable clip arm. In the present invention, the adjusting screw is screwed outward to unscrew the telescopic tooth plate upwards, and the two movable clamp arms can be tightened by cooperating with the engagement between the two sides of the outer wall of the telescopic tooth plate and the rotating gear rings at the tops of the two movable clamp arms. The friction between the brake pad and the fixed tooth disc at the top of the valve stem can increase the resistance when the valve stem rotates, and can reduce the rotation speed of the cutoff plate, thus realizing the throttling of the oil inside the valve body function, while improving the range and accuracy of throttling.
Description
technical field [0001] The invention relates to the technical field of petroleum pipeline transportation, in particular to a pipeline throttle valve. Background technique [0002] Oil and gas field refers to the sum of oil reservoirs, gas reservoirs and oil and gas reservoirs in the same area controlled by a single local structural unit. Oil and gas fields produce oil and gas. In order to collect and transport these resources to the outside, in many cases, it is necessary to set up throttle valves in these fluid pipelines by changing the throttle section or throttle length, controlling the flow rate of the fluid to control the flow of the pipeline, and realizing the flow of the fluid in the pipeline. throttling and step-down. [0003] However, when the existing pipeline throttling valve is used, the oil throttling range of the valve body is small, the adjustment accuracy is poor, and the use of the device is not scientific. Contents of the invention [0004] The object o...
