The purpose of this utility model realizes by following technical proposal: a kind of double spool eccentric rotary regulating valve, comprise main valve plug, auxiliary valve core, valve rod, rotating shaft, trim ring, sealing seat and the valve body with valve pocket, valve body two ends have the import and outlet that are communicated with valve pocket, it is characterized in that, described main valve plug and auxiliary valve core are arranged in described valve pocket, described valve rod is connected pivotly with described valve body, described main valve plug is positioned at entrance point and is arranged on one end of described valve rod prejudicially, the entrance point of described valve body is provided with protruding step, described sealing seat one end face and step lean, the other end and trim ring lean, described trim ring is connected with valve body screw thread, described auxiliary valve core is positioned at outlet end and is rotatably connected in rotating shaft, and described rotating shaft two ends are fixed on valve body, described main valve plug have gear one, described auxiliary valve core have gear two, and main valve plug and auxiliary valve core are engaged by gear one and gear two and linked.
Main valve plug is engaged by gear train with auxiliary valve core, and main valve plug is active rotation, auxiliary valve core driven rotation, when main valve plug turn to several angle make import be in sealing state time, auxiliary valve core also just turns to the position making outlet be in sealing state.Major-minor spool seals respectively, plays double sealing effect, realizes dual fail-safe.
In above-mentioned double spool eccentric rotary regulating valve, described main valve plug has sealed department one and rotation section, and described sealed department one is in umbrella, and rotation section has hexagonal attachment hole, described gear one is positioned on rotation section.Attachment hole is Hexagon, conveniently rotates together with valve rod.
In above-mentioned double spool eccentric rotary regulating valve, described auxiliary valve core has sealed department two and follower, and described sealed department two is in umbrella, and described follower has the through hole passed for rotating shaft, described gear two is positioned on follower.
In above-mentioned double spool eccentric rotary regulating valve, described sealing seat is that rubber material is made.When main valve plug rotates, the contact jaw of sealing seat rubs mutually with the sealed department of spool, can remove the impurity on spool sealed department, plays the function of automated cleaning spool.
In above-mentioned double spool eccentric rotary regulating valve, described gear one is identical with the profile of tooth of gear two, and the number of teeth is identical.
Compared with prior art, this double spool eccentric rotary regulating valve has a valve rod just can drive two valve core rotation, main valve plug sealing import, and auxiliary valve core sealing outlet, realizes double seal.

Fig. 1 is structural representation of the present utility model.
In figure, 1, main valve plug; 2, auxiliary valve core; 3, valve rod; 4, rotating shaft; 5, trim ring; 6, sealing seat; 7, valve pocket; 8, valve body; 9, import; 10, export; 11, step; 12, gear one; 13, gear two; 14, sealed department one; 15, rotation section; 16, sealed department two; 17, follower.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this double spool eccentric rotary regulating valve comprises main valve plug 1, auxiliary valve core 2, valve rod 3, rotating shaft 4, trim ring 5, sealing seat 6 and has the valve body 8 of valve pocket 7, and valve body 8 two ends have the import 9 and outlet 10 that are communicated with valve pocket 7.Main valve plug 1 and auxiliary valve core 2 are arranged in valve pocket 7, and valve rod 3 is connected pivotly with described valve body 8.Main valve plug 1 is positioned at import 9 end and is arranged on one end of described valve rod 3 prejudicially, and import 9 end of valve body 8 is provided with protruding step 11.Trim ring 5 is threaded with valve body 8, and sealing seat 6 one end face and step 11 lean, and the other end and trim ring 5 lean.Auxiliary valve core 2 is positioned at outlet 10 end and is rotatably connected in rotating shaft 4, and rotating shaft 4 two ends are fixed on valve body 8, main valve plug 1 have gear 1, auxiliary valve core 2 have gear 2 13, and main valve plug 1 and auxiliary valve core 2 are engaged by gear 1 and gear 2 13 and linked.Gear 1 is identical with the profile of tooth of gear 2 13, and the number of teeth is identical.
Main valve plug 1 has sealed department 1 and rotation section 15, and sealed department 1 is in umbrella, and rotation section 15 has hexagonal attachment hole, and described gear 1 is positioned on rotation section 15.Auxiliary valve core 2 has sealed department 2 16 and follower 17, and sealed department 2 16 is in umbrella, and follower 17 has the through hole passed for rotating shaft 4, gear 2 13 is positioned on follower 17.
Sealing seat 6 is made for rubber material, can rub mutually during main valve plug 1 rotates with the front end of sealing seat 6.Valve long-term with fluid contact after, especially contain the water body of mineral substance, spool face can cover one deck foreign material, time more long more difficult cleaning.So the rotation of each main valve plug 1 all can rub with sealing seat 6, be equivalent to the impurity that sealing seat 6 wipes spool arcuate surface, play automatic cleaning function.
Working principle: when actuator driven valve rod 3 rotates, valve rod 3 rotates with the main valve plug 1 in moving valve 8, and due to gearing relationships, auxiliary valve core 2 also rotates thereupon.Main valve plug 1 and auxiliary valve core 2 turn on the contrary, reach the object synchronously opened or closed, play double sealing effect.Even if the main valve plug of first 1 seals loosely, the auxiliary valve core 2 of second is still in sealing state, plays double insurance effect.
