Abstract
The utility model relates to a valve technique, particularly a controlling and regulating valve which comprises solid suspended substance particles and easily deposited fluid. The utility model is composed of a cambered cone-shaped valve core, a core sleeve, a drive rod, a valve sleeve, etc. and is easy to be made into a linear valve. Owing to the small friction surface of an opening and closing regulating element in the valve, the utility model can effectively prevent moving parts from being clamped and blocked by particles in the fluid to be stably used for control sections for a long time.
Description
The utility model relates to the control valve technology, is a kind of anti-blockage type arc-taper plung-core control valve.Its control spool is arc subulate, can be used on and contain the solid suspension composition granule, is easy to deposition, easily stops up the flow volume delivery of fluid and regulates control.
Domestic so far common control valve has butterfly valve, angle type plunger valve, introduce day having of present technique production and singly sit modulating valve, cage type regulating valve etc., the spool of these valves is little, the distance that its aperture of spool moves is short, the moving element attrition surface is big, granule in the fluid enters easily resistance to be increased be directed at actuator and drives motionless and stuck, large particle stops up the space of the control fluid of spool and valve core housing easily again and makes flow interrupt control out of control, frequent even the final controlling element of failsafe valve is burnt out, make the manufacture control Halfway Stopping, be difficult to long-term work in the controlling unit of above-mentioned fluid.
The utility model purpose is embodied in, and solves in the production with simple anti-blocking arc-taper plung-core control valve at a low price and contains solid suspended particle, easily the regulating and controlling problem of deposits fluid.
The utility model purpose is achieved in that anti-blockage type arc-taper plung-core control valve mainly comprises arc-taper plung-core, plug core ring set, plug core driveshaft, valve inflow entrance or outflow opening, valve pocket, lubricating cup and seal ring.Its arc-taper plung-core is the tapered plug core that the parabolic degree is arranged, and it and plug core ring set are contained on the same axis in the valve pocket.Plug core ring set is fixed in the valve pocket, and plug core driveshaft one end links to each other with arc-taper plung-core, and the other end passes valve pocket and passes seal ring, passes lubricating cup and links to each other with outer driving arrangement.Under the effect of external force (as final controlling element), make driveshaft drive arc-taper plung-core, along the axial motion of plug core ring set, make between arc-taper plung-core and the plug core ring set and form the different fluid space, valve inflow entrance or outflow opening are connected to an integral body with valve pocket.
Arc-taper plung-core is a shape that is rotated into along central shaft by parabola, also can be formed along central shaft rotation by part parabola, and arc-taper plung-core is by (r R)
2=1-n L design parabola can get linear control valve, appoint and get parabola and get the nonlinear Control valve.
Plug core ring set is a hollow cylindrical sleeve or hollow annulus, and internal diameter is less than or equal to the effectively maximum diameter of the section of use of arc-taper plung-core.
The arc-taper plung-core effectively maximum outside diameter of section equates with valve inflow entrance internal diameter or positive and negative 40% value of valve inflow entrance diameter.
Owing to adopt such scheme, the diameter of arc-taper plung-core is more than or equal to the straight warp of pipe conveying fluid, can be smoothly when valve reaches maximum by straight through for conveyance conduit directly through the particle of 1/4th sizes, moving element has seldom overcome granule and has entered in the gap of attrition surface owing to rub relatively in the valve; Prevented that actuator from taking place because of resistance increases stuck phenomenon.
