Abstract

The invention discloses a sensor valve body for a natural gas pipeline, comprising a flow limiting portion and a flow metering portion; the flow limiting portion is provided with an intake passage, agas transition groove and a first exhaust passage; the intake passage and the first exhaust passages are both connected with the gas transition groove; the flow metering portion is provided with a rotor mounting groove and a second exhaust passage; and the second exhaust passage is in communication with the first exhaust passage and passes through the upper portion of the rotor mounting groove. The mechanism of the present invention is simple and easy to install and manufacture.

Description

technical field [0001] The invention relates to the field of natural gas transportation, in particular to a sensor valve body for a natural gas pipeline. Background technique [0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oil field gas, gas field gas, mud volcano gas, coal bed methane, and biologically generated gas, etc.). The definition of "natural gas" that people have used for a long time is a narrow definition from the perspective of energy, which refers to the mixture of hydrocarbon and non-hydrocarbon gases naturally stored in the formation. In petroleum geology, it usually refers to oil field gas and gas field gas. Its composition is dominated by hydrocarbons and contains non-hydrocarbon gases. [0003] In the process of natural gas transportation, it is necessary to adjust the flow of natural gas through the flow regulating valve...
