Description

A kind of inner curve valve pneumatic controller

Technical field:

The utility model relates to fields such as oil, chemical industry, metallurgy, pharmacy, is specifically related to a kind of valve pneumatic controller.

Background technique:

Before the utility model uses, China utility model patent 96235310.8 by the agency of about the inner curve Pneumatic gate valve, but also there is following shortcoming in this patent: 1, the distribution of the pneumatic motor of Pneumatic gate valve partly adopts screw to prop up the way generation top power on top, such design shortcoming is: on-the-spot vibration is bigger, long-time vibration can make jackscrew loosening, does not have the effect of jackscrew; On-the-spot corrosivity is strong, and jackscrew is easy and the bearing seat rust is dead, dismantles cumbersome; The jackscrew upper end is exposed outside, and to comparatively ugly on the product appearance, the time has been grown also rotten easily rust.2, the crossbeam of pneumatic motor inside is real crossbeam, and the comparison heaviness that such shortcoming is to make this pneumatic motor to become produces excessive inertia and produces stuck phenomenon with floral disc up and down easily, is installed in and breaks valve rack on the valve body easily.3, the planet carrier center hole is a thread, only singly joins a kind of valve rod of valve, and the onsite user must survey and draw when requiring to change valve again, the waste installation time.Not quick detachable when 4, piston is the solid piston installation and maintenance, because a pneumatic motor uses many group pistons, so the heaviness more that allows this product become.

The field control case partly adopts common pneumatic element (rotary valve), switch is all wanted manually opened or is cut off source of the gas, through field observation for many years, a lot of operators often forget and close rotary valve, thereby make source of the gas apply air pressure to controller, long-term power causes distortion can for the screw rod of valve or twist into twisted shape always.

The model utility content:

The purpose of this utility model provides a kind of inner curve valve pneumatic controller, it utilizes pressurized air that power is provided, and substitutes manual operation, and can realize concentrating the telemechanical control valve to open and close and the aperture adjusting, alleviate labor intensity of operating personnel greatly, exempt the operation of climbing to a higher point.And this product is an intrinsic safety, is suitable for using at various inflammable and explosive work condition environments, and it has a cover handwheel simultaneously, need not pneumatic one manually switching, can supply operation at any time, and operation is lightly nimble.Adopt many rotary types driving mechanism, drive the gate valve screw rod, interrupting in air failure under the situation of air feed still can the maintaining valve invariant position, thus this product more electronic, surge and the cylinder type gate valve is more advanced, convenient, reliable, safety, adaptability is strong.

In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises hollow main shaft 1, handwheel 3, interior gas distribution plate 5, outer gas distribution plate 6, inner curve loam cake 7, T type crossbearer 8, combined cylinders 9, mountain type piston 10, goes up floral disc 11, following floral disc 12, inner curve lower cover 14, ring gear 15, deceleration box 16, planetary pinion 17, planet carrier 18, little axle 19; Hollow main shaft 1 links to each other with planetray reducer 17, hollow main shaft 1 is provided with radially cylinder 9 of three layers of coaxial combination, radially be furnished with six mountain type pistons 10 in the cylinder 9, be provided with floral disc 11 and following floral disc 12 at combined cylinders 9 two ends, gas distribution plate 5 on combined cylinders 9 upper ends, being provided with above the floral disc 11; The mountain type piston 10 of every group of cylinder 9 is over against a T type crossbeam 8, T type crossbeam 8 two ends are provided with roller 21, bearing can be along the inner curve orbiting that is fixed on motor inner curve upper cover body 7 and inner curve lower cover 14, and the inner curve track has acting sections such as 4 or 6 or 8 or 10 or 12.Hollow main shaft 1 upper end has been provided with manual handwheel 3, and valve rod can pass planet carrier 18 center holes and hollow main shaft 1 center hole.

The utility model source of the gas footpath gas source interface is by the effect of interior gas distribution plate 5 and outer gas distribution plate 6, pressure enters every group of combined cylinders 9 active chambers successively, promoting mountain type piston 10 stretches out, mountain type piston 10 promotes main shaft diameter to T type crossbeam 8, make roller 21 along the inner curve orbiting, thereby hollow main shaft 1 is rotated, and by planetary gear speed reducing mechanism ring gear 15, deceleration box 16, planetary pinion 17, planet carrier 18, little axle 19 makes the valve rod moving linearly, if gas distribution plate 5 in changing, the gas source interface of outer gas distribution plate, then change the sense of rotation of hollow main shaft 1, valve rod is then done reversing motion; Then only need to rotate handwheel 3 in the time of manually, handwheel 3 and hollow main shaft 1 drive the valve rod moving linearly by planetary gear speed reducing mechanism ring gear 15, deceleration box 16, planetary pinion 17, planet carrier 18, little axle 19.

The utlity model has following beneficial effect: utilize pressurized air that power is provided, substitute manual operation, and can realize concentrating the telemechanical control valve to open and close and the aperture adjusting, alleviate labor intensity of operating personnel greatly, exempt the operation of climbing to a higher point.And this product is an intrinsic safety, is suitable for using at various inflammable and explosive work condition environments, and it has a cover handwheel simultaneously, need not pneumatic one manually switching, can supply operation at any time, and operation is lightly nimble.Adopt many rotary types driving mechanism, drive the gate valve screw rod, interrupting in air failure under the situation of air feed still can the maintaining valve invariant position, thus this product more electronic, surge and the cylinder type gate valve is more advanced, convenient, reliable, safety, adaptability is strong.
