Description
Technical field
The utility model relates to design and the manufacture of valve, is widely used in liquid in the instrumentation pipelines such as all kinds of flows, differential pressure, pressure of industrial automation control system or keying and the control gear of gas.
Background technique
At present, the instrument three valve groups of extensive use all realize sealing by filler, during operation, need rotatable handle or handwheel band ovable valve stem directly under the effect of stuffing box packing internal spiral lifting, to carry out and open and close, because valve rod spiral lifting produces very large frictional force and friction ractor in stuffing box packing, so easily wear and tear and operate effort, affect working life and the pressure-resistant seal performance of valve.
Summary of the invention
Large in order to overcome existing instrument three valve group packing seal position frictional force and friction factor, deficiency easy to wear, the invention provides a kind of filler and spool and do not rotate double-sealing and upper valve rod sealing configuration again, make its friction factor minimum, sealability excellence, safe and reliable, long service life, operates free and relaxed.
The technical solution of the utility model is:
1, a kind of Novel meter three valve groups, by spool, valve gap, filler, Packing seat, steel ball, gland, locknut, valve rod, sealing gasket, seal ring, sealed pressure pad, gland nut, the compositions such as valve body, it is characterized in that: valve body is three integrated carriers of valve being processed into by a cuboid, three internal thread valve pocket B that coordinate with valve gap are distributed in two ends and the medium position of valve body, the perpendicular both sides end face of internal thread valve pocket B at valve body two ends have respectively into, outlet screw thread, import thread bottom hole A communicates with internal thread valve pocket B lower hole E, outlet thread bottom hole C communicates with internal thread valve pocket B, two ends internal thread valve pocket B base apertures F, one end communicates with middle part internal thread valve pocket B lower hole D, and the other end communicates with middle part internal thread valve pocket B, there is respectively a symmetrical mounting hole G internal thread valve pocket B both sides, middle part.
2, one end of spool is cone, and the top opposite position of cone is equipped with an angle and is connected with cylindrical, and the other end is hole, and the bottom in hole is plane, uniform multiple apertures on the relevant position of its circumference; The lower end surface of valve rod is circular arc, is inserted in the hole of spool, and circular arc end face is contacted with the base plane in hole, has both been conducive to active force and has been uniformly distributed at the center of spool, is conducive to again reduce frictional force; In each aperture, pack the steel ball of same size into, steel ball is placed in the groove of stem lower portion simultaneously, valve rod is screwed in gland together with spool and the steel ball that is contained in aperture simultaneously, make spool by steel ball and valve rod active couple together, the active linkage structure of formation steel ball.The two ends of filler have respectively Packing seat to be placed in the bottom in valve gap, valve rod and spool pass valve gap and filler and Packing seat to appropriate location, locknut is threaded to the thread root of gland, gland is screwed in valve rod and valve gap, make its end face push down Packing seat and filler, and valve rod is threaded to the topmost part, form bonnet assemblies.
3 valve gaps screw in respectively three internal thread valve pocket B of valve body fastening, form linearly firmly to seal between the internal thread valve pocket B oral area of valve gap and valve body; Regulate and screw gland, make it promote Packing seat filler is pressed between spool and valve gap, form packing seal structure, locknut is screwed to locking.In the upper end of gland, be provided with top sealing configuration again, sealing gasket, seal ring and sealed pressure pad are placed between valve rod and gland respectively in order, regulate and screw gland nut and make to seal between its seal ring and valve rod and gland.Rotatable handle or handwheel, band ovable valve stem spiral lifting, under the effect of the active linkage structure of steel ball, makes spool in stuffing box packing, not rotate upper and lower straight line motion, carries out and opens and closes.
While 4, opening valve, the interior step H closure of the reverse angle of spool and valve gap, forms and opens back seal structure.
5, three integrated each architectonicals of valve, communicate with both sides valve while opening middle valve, and while closing middle valve and both sides valve cuts off.
Advantage of the present invention and beneficial effect are:
1, combined type valve gap design, makes valve can keep highly complete sealability and operating characteristics in various severe applied environments.
2, spool rotary lifting movement not in filler, frictional force and fricting movement amount minimum, the sealability of valve is more excellent, and the life-span is longer.
3, between valve rod and spool, adopt the active linkage structure of steel ball, spin friction active force is dropped to minimum, make the operation of valve free and relaxed.
4, because packing seal is at spool and valve gap bottom position, isolated with medium, be conducive to the lubricated impact that is not subject to medium of all motive position such as screw thread and the active linkage structure of steel ball.
5, You San road packing seal structure, has formed the reverse sealing function of spool while opening valve and the retrocession function of packing seal function and seal ring sealing, and sealability is more safe and reliable.
6, due to the seal action of upper sealing gasket, make it with outside isolated, be not subject to external environment influence.
7, prevent from becoming flexible after valve closing, be particularly suitable for being applied in the occasion of vibrations.
