Embodiment
Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
Referring to Fig. 1-Fig. 3, a kind of pneumatic control angle seat valve of the present invention, by viewing window 1, aluminum alloy upper end cap 2, aluminum alloy cylinder barrel 3, indicating arm 4, locking nut 5, spring 6, piston ring 7, suction port 8, aluminum alloy lower end cap 9, oil-impregnated bearing 10, Y-shaped ring 11, polymeric seal assembly 12, Packing spring 13, piston 14, connect 15, valve rod 16, valve body 17, spool 18, valve port 19 forms, wherein, the aluminum alloy upper end cap is connected with the aluminum alloy cylinder barrel by seal ring, viewing window is fixed on aluminum alloy upper end cap central authorities, indicating arm one end is positioned at viewing window, the other end is connected with locking nut, locking nut is connected with valve rod, valve rod is fixed on the central authorities of piston, one end of spring withstands on the aluminum alloy upper end cap, the other end withstands on the piston, the suction port that is used for the unlatching of controlled angle seat valve or closes is positioned at the bottom of aluminum alloy cylinder barrel, described valve rod is connected with the aluminum alloy lower end cap by oil-impregnated bearing, between valve rod and aluminum alloy lower end cap, also be provided with Y-shaped ring, the gap that is used for sealed valve stem and aluminum alloy lower end cap, described aluminum alloy lower end cap is connected with connecting base, connecting base is connected with valve body, be provided with polymeric seal assembly and Packing spring between described valve rod and the connecting base, described valve rod end is connected with spool, this spool is positioned at the upper end of valve port, described aluminum alloy inner wall of cylinder be provided with the reticulate pattern surface, lubricant film can be arranged after smearing lubricating grease on this reticulate pattern surface.
The bottom of described valve body is cylindrical tube, and two ends are used for the connecting media pipeline, and valve body top is cylindrical tube, is used for connecting valve rod, connecting base, and valve body top and valve body lower portion are structure as a whole, and the angle between valve body top and the valve body lower portion is acute angle.
The top of described aluminum alloy cylinder barrel also has additional a suction port, and this suction port is used for angle pedestal valve when closing, and makes valve core reset with pressure one same-action of the control gas of spring force and the input of this suction port.
Working principle: as shown in Figure 2, angle pedestal valve is in closed condition under the effect of spring force under the original state, and medium can not pass through.Behind the control gas that passes into certain pressure at suction port, piston lifts spring-compressed by valve rod band movable valve plug, and medium passes through from valve.Behind the stop supplies control gas, spool resets under spring-force driven dual again, with valve closing.The present invention comes the circulation of control media by gas, easily realize centralized control and remote control, helps enterprise to improve automatization level.The present invention can according to actual needs, join valve body and the final controlling element of different size.
Single action: single action and two moving dividing are arranged.Two moving meanings are to also have a suction port (shown in Figure 3) above piston, in the time of valve closing, not only reset by spring force, can also pass into control gas at this suction port, make valve core reset by spring force and pressure one same-action of controlling gas.Can make like this sealing of spool place better, the pressure medium that can bear is larger.And if two moving, the gas flow in the final controlling element all is to carry out in the environment of sealing, has isolated the impurity such as the steam in the working environment, dust.
Normally closed: have normally closed and often open minute.Normally closed be exactly angle pedestal valve initially be exactly closed condition, pass into control and it opened behind the gas.Often opening is that angle pedestal valve initially is being exactly opening state, passes into control and it is closed behind the gas.Normal opening structure and normally closed structure (seeing Fig. 2) are so slightly different, spring in the normal opening structure final controlling element is below piston, spool is in lifting status always under spring-force driven dual, will pass into control gas spring-compressed in the suction port (normal angle of release seat valve all is two moving angle pedestal valves) on piston when closing, and spool be depressed closed angle pedestal valve.
Obviously, above-mentioned example of the present invention only is for example of the present invention clearly is described, and is not to be restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give all mode of executions exhaustive.Everyly belong to the row that apparent variation that technological scheme of the present invention extends out or change still are in protection scope of the present invention.
