[0016] Such as figure 1 As shown, the gas-liquid separation chamber is set at the bottom of the valve body and consists of a valve seat, a lower valve body, and a filter screen. The internal conical structure and side-opened double-hole drainage and multi-layer filter screen form an ideal collision and gravity In the oil and gas separation chamber, the gas-liquid mixture flows through the mesh filter bed, the gas rises along the fluid channel, and the liquid settles and flows back into the pipe to achieve preliminary oil and gas separation; the gas flow removal chamber (exhaust process) is set on the upper part of the valve body, Composed of fluid, air float, adjusting polished rod, spring, adjusting screw and upper valve body, etc., the air flow can be completely introduced into the oil mist trapping section. The exhaust test condition of air float is at ambient temperature 15-28℃, pressure>1 ×10 2 Pa gas can be discharged continuously; the oil mist trap is installed on one si...
