Abstract
The invention discloses a heating furnace burner valve actuator. The heating furnace burner valve actuator comprises a cylinder and a transducer, wherein the cylinder consists of an upper cylinder body, a membrane, a tray, a piston rod, a spring, a lower cylinder body, a fixed sleeve and a double-fisheye bearing, the transducer consists of a stroke regulator, a supporting seat, a shift fork and a swing arm. The heating furnace burner valve actuator has the main advantages that the service life of an actuating mechanism is prolonged and maintenance is reduced. The movement of the piston rod adopts a rolling bearing guide structure and the double-fisheye bearing, thus eliminating the friction of the membrane and the cylinder wall, prolonging the service life of the membrane, and eliminating the blocking phenomenon of the actuator in maximum or minimal openness.
Description
Technical field
The present invention relates to a kind of valve actuating device, relating in particular to a kind of E80 is special-purpose row oven burner valve actuating device.
Background technique
Present similar technology or akin product are external import; Domestic also do not have similar or approximation technique at present; It is poor that the major defect of external like product shows as working life; Break time is long, often occurs that diaphragm damages, final controlling element occurs getting stuck at maximum or minimum position, and phenomenon, connecting rod fracture easily, the phenomenons such as instrument of needs special use when installing and using.Can't satisfy oven quantity-produced particularity.
Summary of the invention
The present invention seeks to provides a kind of oven burner valve actuating device to the defective that existing technology exists.
The present invention adopts following technological scheme for realizing above-mentioned purpose:
A kind of oven burner of the present invention valve actuating device is made up of cylinder and transducer, and wherein cylinder comprises: upper cylinder body, diaphragm, pallet, piston rod, spring, lower cylinder body, fixed cover and Pisces axis oculi hold; Transducer comprises: travel adjustment, supporting base, fork and swing arm; Isolate through diaphragm between upper cylinder body and the lower cylinder body, pallet is arranged at the bottom that the lower cylinder body top is a diaphragm, between the bottom of lower cylinder body and the pallet spring is set; The bottom of lower cylinder body is provided with fixed cover; One end of piston rod is connected with pallet, and the other end of piston rod gets into fixed cover and flexibly connects with a end that the Pisces axis oculi holds, and the other end that the Pisces axis oculi holds gets in the supporting base and flexibly connects with an end of swing arm; One end of swing arm is fixed in the supporting base through fork, the corresponding travel adjustment that is provided with swing arm in supporting base bottom.
Preferably, said diaphragm top is provided with the diaphragm gland.
Major advantage of the present invention is the working life of having improved actuator, has reduced maintenance.Adopted rolling bearing guide structure, Pisces axis oculi to hold for the motion of piston rod; Having stopped the imbalance mill that diaphragm and cylinder ward off examines; Improve the working life (reaching working life 1,000,000 times) of diaphragm; Fast shut-off time≤1s has stopped the stuck phenomenon that final controlling element occurs in the maximum or minimum aperture of frequent switch.

Embodiment
Like Fig. 1, shown in Figure 2; A kind of oven burner of the present invention valve actuating device is made up of cylinder and transducer, interfixes through screw 17, packing ring 19 and spring washer 18; Wherein cylinder comprises: upper cylinder body 4, diaphragm 9, pallet 10, piston rod 11, spring 15, lower cylinder body 16, fixed cover 20 and Pisces axis oculi hold 33; The Pisces axis oculi holds 33 two ends and is fixedly connected with locking nut 32 through bolt 21, nut 23, and transducer comprises: travel adjustment, supporting base 22, fork 26 and swing arm, through covering capable nut 1 and 5, O type circle 2 and 7, screw 3 piston rod 11 and upper cylinder body 4 and lower cylinder body 16 are fixed simultaneously; On the said nut 5 nut fixed cover 6 is set also; Be symmetrical set case lid 24 on the supporting base 22 and be fixedly connected with the two ends of fork 26, a side of supporting base 22 also is provided with cover plate 30, and said cover plate 30 is fixing with supporting base 22 through screw 31; Isolate through diaphragm 9 between upper cylinder body 4 and the lower cylinder body 16; And interfix through screw 12, packing ring 13 and spring washer 14, it is the bottom of diaphragm 9 that pallet 10 is arranged at lower cylinder body 16 tops, between the bottom of lower cylinder body 16 and the pallet 10 spring 15 is set; The bottom of lower cylinder body 16 is provided with fixed cover 20; One end of piston rod 11 is connected with pallet 10, and the other end of piston rod 11 gets into fixed cover 20 and holds an end of 33 with the Pisces axis oculi and flexibly connects, and the Pisces axis oculi holds that 33 the other end gets in the supporting base 22 and flexibly connects through coupling shaft 25, nut 27 with an end of swing arm; One end of swing arm is fixed in the supporting base 22 through fork 26, the corresponding travel adjustment that is provided with swing arm in supporting base 22 bottoms.Travel adjustment is made up of bolt 29 and nut 35.
Said diaphragm 9 tops are provided with diaphragm gland 10.What the present invention was that E80 series oven burner special valve actuating device (claiming scrolling film plate formula actuator again) adopts is the cylinder of column construction form.Its working principle: under the effect of gas, the part between pallet and the sleeve lining becomes circular arc, when pallet moves up and down; This circular arc is done nonslipping rolling along sleeve lining and pallet outer wall, makes the cylinder moving of straight journey become the motion of angle stroke through transducer, thus the switch of control valve; Because the support of rolling bearing is arranged, actuator is when work, and pallet can not squint because of the variation of stroke; Even touch cylinder wall, and can not produce mill and examine, thus the working life of having improved diaphragm greatly; Improved 30% than the external like product life-span approximately, reduced maintenance.Scrolling film plate formula actuator adopts flexible membrane, and this diaphragm places between the diaphragm case of two drawings or casting, go up bellows in two synthetic air chambers and be make pressure-tight.Scrolling film plate formula actuator has " scope " spring usually, and with the power that balance actuator produces, the pneumatic signal of regulating system is received pressure-tight air chamber; The increase of signal or minimizing form a power; In order to overcome the unbalanced force that pressure drop causes in air chamber, the frictional force in (stuffing box) and the spring force of actuator are because the wiper seal air chamber of scrolling film plate formula actuator is positioned at the top of diaphragm; When pressure increased in this air chamber, valve rod moved downward.
