A kind of tilted conical surface multiple-way valve
Technical field the utility model relates to a kind of tilted conical surface multiple-way valve that gathering lines such as oil, chemical industry use.When making the rotation fuse turn to certain angle by (electronic or manual) motivational drive, the inner public water conservancy diversion metering of middle rotation fuse duct is communicated with the some oil inlet holes of valve body tilted conical surface, thereby realize metering rotation gating, and other valve body tilted conical surface oil inlet hole comes liquid to compile to flow out from the lower chamber side opening to enter gathering line.
Background technique is applied to the multiple-way valve of petroleum industry field at present, mainly contains two kinds of forms: plane sealing (seeing patent 200420006528.1) and cylinder sealing.Its structural feature of plane sealing rotation multiple-way valve is uniform several filler openings on planar circumferential, (", 4 " or 5 ") as 3; when the pressure rank is higher; mean that body size is big, wall thickness is thicker, price is higher, just lost the superiority under high pressure stage sorrow of separation condition like this when the filler opening size is big.Yet its valve base sealing ring wear compensation is to be provided by elastic element for cylinder sealing rotation multiple-way valve, when an amount of seal wear end cycle, need stop well servicing, at this moment need to open flange that comes the liquid entrance of cylinder sealing rotation multiple-way valve, regulate to make the elastic element pressurized with special-purpose adjustment means, and then apply valve base sealing ring seal pressure and resume production.The utility model is the multiple-way valve between a kind of tilted conical surface seal form of plane sealing and cylinder sealing.The compensation of soft or hard bivalve seat seal wears can be provided with the axial external world by elastic element and apply, and bidirectional modulation compensate for wear amount so just prolongs a life cycle.
The summary of the invention the purpose of this utility model provides a kind of multiple-way valve of tilted conical surface seal form, it is characterized in that: a kind of multiple-way valve between plane sealing and cylinder sealing, the axis normal of soft or hard bivalve seat seal ring is in the inclined-plane that matches, soft or hard bivalve seat seal ring seal specific pressure is to provide by elastic element, when compensate for wear exhausts, under situation about not stopping production, can go forward one by one downwards by the adjusting nut of rotary valve mandrel upper end by the valve body peripheral operation, at this moment obtain a sin α * Δ y compensation rate at soft or hard bivalve seat seal ring, continue to keep production and effectively prolong a life cycle.
The utility model is achieved like this: this tilted conical surface seals multiple-way valve by valve body, lower slider support ring, " O " shape seal ring down, rotary spool, interior six side's adjusting nuts, ripple spring seat ring, inner ring ripple spring, outer ring ripple spring, auxiliary seal are scraped husky ring, soft seal ring, scrape husky ring " o " shape seal ring, soft seal ring " o " shape seal ring, seal washer, valve body " o " shape seal ring, connecting bolt, nut, spindle nose " O " shape seal ring, tapered roller bearing, fixing bolt, regulate fixed plate, adjusting nut, compositions such as bonnet.When making the rotation fuse turn to certain angle, realize that the inner public water conservancy diversion metering of rotation fuse duct is communicated with the some oil inlet holes of valve body veneer, thereby realize metering rotation gating by (electronic or manual) motivational drive.
The utility model compared with prior art has the following advantages: 1, the axis normal of soft or hard bivalve seat seal ring is in the valve body that matches (1) inclined-plane, soft or hard bivalve seat seal ring seal specific pressure is that the elastic element by separately provides, and it is harmonious to reach the compensate for wear amount.2, under situation about not stopping production, can go forward one by one downwards by the adjusting nut (21) of rotary spool (4) axle upper end in the valve body peripheral operation, be delivered on the rotary spool (4) by tapered roller bearing (18), obtain a sin α * Δ y compensation rate at soft or hard bivalve seat seal ring place and continue sealing compensation, the manufacture cycle is effectively prolonged.

Embodiment
With one 8 logical individual well inlet DN100mm latus rectum, the tilted conical surface multiple-way valve of metering outlet DN100mm and collection output DN200mm is an example: valve body in Fig. 3 (1) is the casting processing part, dip hatch comes the consistent DN100mm of liquid mouth flange with 8 individual wells, collection outlet flange is that DN200mm all forms with valve body (1) butt welding, valve body (1) scrapes husky ring (9) with auxiliary seal and soft seal ring (10) fitted seal bevel angle is 15 °, take sclerosis and polishing to handle to valve body (1) tilted conical surface, rotary spool (4) cast inblock processing, soft seal ring (10) the processing axis normal of rotary spool (4) is in the tilted conical surface of valve body (1), become 15 ° with horizontal plane, it is the same that the matching trim processing that auxiliary seal is scraped husky ring (9) and soft seal ring (10) is processed with cylinder sealing multiple-way valve, and bonnet (22) is finished through casting processing.During assembling seat ring parts: interior six side's adjusting nuts (5) are screwed into the valve seat mouth lower curtate of rotary spool (4), put into ripple spring seat ring (6) successively, inner ring ripple spring (7), outer ring ripple spring (8), scrape husky ring " o " shape seal ring (13), auxiliary seal is scraped husky ring (9), the soft seal ring (10) of band soft seal ring " o " shape seal ring (11).Pack into rotary spool (4) assembly in the valve body (1) and aim at an individual well and come the liquid flange mouth, seat upper sealing washer (12) between bonnet (22) and valve body (1), cover bonnet (22), tighten 16 M36 stud bolts (16) nuts (15), come the liquid flange mouth to enter with six side's adjustment means in special-purpose from individual well, six side's adjusting nuts (5) make inner ring ripple spring (7) and outer ring ripple spring (8) elastic element pressurized maximum distortion in regulating, scraping husky ring (9) and soft seal ring (10) to auxiliary seal applies and seals the maximum contact specific pressure, put into tapered roller bearing (18) at the upper tip of rotary spool (4), screw in adjusting nut (21), put interior six sides in adjusting nut (21) upper end and regulate fixed plate (20), tighten anti-turn screw (19).
