Ordinary cylindrical plug valves often use four kinds of tightly closed way, it is using tightly closed agent, using the valve plug expansion, use 0 tightly closed circle, unfair cock wedge seat tightly closed circle. Cylindrical oil plug valve tightly closed against the plug and body tightly closed between agent to achieve. Because of the tightly closed surface position in the whole paper is trying to take care and do not contact with the liquid medium, so the lubricating oil plug valve is especially suitable for use in abrasive medium. 。 Once because the necessities to protect or former because tightly closed agent choose not ready, or in a tightly closed between the surface had formed crystals and plug in the body can't turns, is sure to execute completely finishing or repair the valve. Tightly closed agent is perfusion with screw or injection gun by the valve plug stick tightly closed, because this when the valve is in use, can be tightly closed after injection supplies agent to help to remedy the tightly closed is not sufficient. Q: cylindrical plug valves introduction a: cylindrical plug valves used in a certain extent, depends on what initiation tightly closed between plug and body condition. Cylindrical plug valve, the valve body is equipped with a teflon sleeve and the valve plug tightly closed, it USES compression nut pressure inside the body, by the valve plug expansion force of teflon sleeve to tightly closed. But not suitable for throttling lubricating oil plug valve, this is because the throttling special cases from rinse tightly closed tightly closed surface agent, so often closed, Industrial Valves for seat tightly closed to our buyer. The lack of this valve is to add tightly closed agent done regularly to be artificial, think appropriate semi-automatic injection is used to overcome the lack of, but need to increase the cost of shipping facilities with valve.
