In the cylindrical plug, square channel normal growth; In the tapered plug, the channel into a ladder type. 0. Below 4, reperfusion tightly closed fat ability guarantee to fulfill the requirements of tightly closed. The style to make the structure of the cock and lighter, but also had a certain loss. This default can be make the plug valve is suitable for use in tall pressure, can reach C12500 level. 。 To achieve such a high pressure can still keep tightly closed, mainly depends on the plug and body tightly closed to the machining precision and surface finish. Pressure balance inverted cone plug valves, valve plug by elements of the cover the screw in the position adjustment, and tightly closed agent from filling the body at the end of the valve stem. Taper of the plug and body tightly closed to absolutely identical, and surface finish Numbers must be in R. In order to avoid the media pressure to push the plug valve seat, valve plug end with balanced holes, small head of equilibrium and the plug hole with medium to small head end only check valve, it can make the medium pressure in the cavity at the ends of the valve plug. The valve tightly closed also depend on the plug and body tightly closed between agent to achieve success. Q: principle of conical plug valve tightly closed a: t cock valve is closed or plunger type rotary valve, rotated 90 degrees to make the valve plug of tong road intersection of the body through or separate, to achieve a valve open or closed. Plug valve is the most suitable for as truncation and through media and shunt is suitable for use, but according to the nature of the suit to use and tightly closed surface erosion resistance, sometimes also can be used for throttling. Cock valve can into cylindrical or conical valve plug patterns. At this time will not because the media pressure will plug into the Marine valve seat cone surface and can not operate. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
