Abstract
The invention provides a miniature friction-less multifunctional valve, comprising a valve body, a valve cover, a valve base, a sealing ring, a pressing plate, a valve pin, a sleeve, a cam, a valve rod, a seal housing, a pressing cover and an O-shaped ring, characterized in that : the valve base is screwed into the valve body on the left end, on the joint of them, a seam-cross screw is mounted, the valve pin is supported in the channel between the valve body and valve cover by the sleeve, between the inner chamber steps of the valve body and the valve pin convex bench, a spring is arranged, the spring is positioned by a guide bar, the guided bar is inserted into the relative holes of valve body and valve cover through the valve pin convex bench, the valve bar is fixed to the cam by bolts or welding. The invention can realize reliable switching, and also can be used for adjusting, and there is no friction on between the sealing faces, which prolongs the useful life.
Description
Technical field [0001] The invention relates to a fine and small non-friction multifunctional valve on a pipeline which can not only cut off but also regulate medium flow, and is a valve device. Background technique [0002] For all kinds of valves currently used in metallurgy, petrochemical, municipal and other fields, although the ball valve only needs to be rotated 90° when opening and closing, the opening and closing is rapid and the seal is reliable, but it can only be used for interception, not for flow adjustment; Although the flow valve can both cut off and adjust the flow of medium, but to complete an opening and closing action, the valve stem needs to rotate dozens of times, and the opening and closing time is too long. Contents of the invention [0003] In order to overcome the shortcomings of the existing ball valves that cannot adjust the flow rate and the opening and closing time of the stop valve and the throttle valve are too long, the present invention pro...
