Metering device for condensate natural gas pipelines facilitating use of turbine flowmeter

[0019] Such as figure 1 As shown, a condensate natural gas pipeline metering device that is convenient to use a turbine flowmeter includes a fluid pipeline 1 and a metering device 5 arranged on the fluid pipeline 1, and a separation tank 4 is connected in series on the fluid pipeline 1, The separation tank 4 is located at the front end of the metering device 5, and the fluid pipeline 1 on the outlet side of the separation tank 4 is connected to the top or the side of the separation tank 4, and a spiral separator 41 is also arranged in the separation tank 4, and the spiral separation The device 41 is a barrel-shaped structure with an inlet at the lower end, an outlet on the side, and a spiral flow channel between the inlet and the outlet. The fluid pipeline 1 on the outlet side of the separation tank 4 is connected to the outlet of the spiral separator 41. , The separation tank 4 is also provided with a liquid outlet pipe 3, and a shut-off valve 6 is connected in series on the liq

[0022] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, the fluid pipeline 1 on the inlet side of the separation tank 4 is connected to the top of the separation tank 4 as a structural form that also reduces the influence of the airflow at the inlet of the separation tank 4 on the condensate.

[0023] In order to facilitate the regular removal of solid impurities in the separation tank 4, the bottom of the separation tank 4 is also provided with a drain pipe 2.

[0024] As a structure convenient for draining the accumulated liquid in the separation tank 4 , the inlet section of the liquid outlet pipe 3 is connected to the bottom of the separation tank 4 .

[0025] As a structural form with simple manufacture and convenient installation, the separation tank 4 is a pressure vessel with elliptical heads at both ends.
