Instrument needle valve function is turned on and off the pipeline path

Instrument needle valve function is turned on and off the pipeline path. Good sealing needle valve, needle valve long service life, even after the needle valve sealing surface damage, needle valves only need to replace wearing parts, needle valves can continue to use. Needle valve should be installed so that the flow is consistent with the direction of the arrow on the valve body medium. Needle valves are often used with pressure transmitters, Trunnion ball valves flow meters and other ancillary equipment. Stainless steel needle valve is used to adjust the carrier gas flow rate, and some instruments use it to control the flow of gas and air. Adjustment handle on a connection in a straight shaft, which stem in the lower end of the shaft that was pointed cone valve needle 5, by changing the relative position of the valve needle valve to control the flow. When adjusting the handle rotated in a counterclockwise direction,Instrument needle valve the gap increases with the valve needle valve, gas resistance decreases, thus increasing the outflow from the needle valve gas flow. When adjusting the handle is turned clockwise, the valve needle valve seal will hold him down, the needle valve is closed. Embed a fluorine rubber gasket groove in the middle of the stem. I.e., the seal ring 4, and its surface is coated with silicone vacuum grease, the stem moves when the seal ring is always in close contact with the inner wall of the valve body, the valve body to maintain a sealed state when the needle valve is not working, the needle valve should be full (this point and the regulator valve opposite) to prevent the valve needle stuck in the valve inlet seal also prevents the spring prolonged pressure and failure.
