Abstract
The utility model relates to a rapid cutting regulating butterfly valve. The utility model is characterized in that a pneumatic actuator of an actuating mechanism and a manual hydraulic system are connected skillfully; two piston rods are connected and arranged at the same center line; the actuating mechanism is directly connected with the butterfly valve; a valve plate shaft and a positioning device are linked directly to improve the regulating precision; the actuating mechanism can receive the exchanging use of the analog quantity and the switch quantity of two signals (a gas signal and an electric signal), and the butterfly valve can be cut off and turned on quickly; the hydraulic system is also provided with a combined hydraulic check valve to make the hydraulic system have the self-locking ability. The utility model is the rapid cutting regulating butterfly valve which is especially suitable for a high-viscosity medium with particles and an oil refining catalytic system.
Description
The utility model is the improvement invention about Pneumatic butterfly valve, be widely used in realizing on the industrial automatic control flow process pipeline such as oil, chemical industry, electric power, metallurgy, light industry regulating automatically or cutting action, be specially adapted to the medium of high viscosity band particle and the fast shut-off of refining catalytic system and regulate butterfly valve.
Existing Pneumatic butterfly valve has ZSCW and two kinds of series of ZMAW, its structure is made up of parts such as ZSC piston or short stroke actuator, valve body, link, positioning work pieces, because (between actuator and valve body, valve body and the positioning work piece) all is partial installation between the parts of this Pneumatic butterfly valve, connect with the parallelogram link, like this, just influenced degree of regulation, this Pneumatic butterfly valve can only be accepted single signal (analog amount or switching value) of planting, and switching value gamut speed is slower, generally in 8-12 second, incompatibility fast shut-off occasion.
In view of the deficiency of known technology, the purpose of this utility model be design a kind of simple in structure, degree of regulation is high, (being analog amount and switching value) exchange is used to accept two kinds of signals, and can fast shut-off and the adjusting butterfly valve of unlatching.
The utility model is finished as follows: oil cylinder (1), cylinder (2), piston rod (10), swing arm (12), positioning work piece (4), hand behaviour mechanism (3), combination Pilot operated check valve (13), equilibrium valve (8,9), switching valve (15), solenoid valve (16,17) etc. are formed long stroke actuators, cylinder (2) is installed with the overlapping disjunctor of oil cylinder (1), the piston rod of cylinder and oil cylinder (10) interconnects, and on same center line.Butterfly valve is made up of valve body (6), valve plate (5), valve shaft (7), swing arm (12) is linked by bearing pin (11) with piston rod (10), and the valve shaft end is provided with groove (19) and is complementary and directly interlock with the convex surface (20) that positioning work piece feeds back cam end portion.
Analog amount adopts valve positioner, and switching value adopts the solenoid valve executive component, and distribute on same loop open circuit and closed circuit structure realize.Butterfly valve adapted pneumatic longstroke servo is accepted the analog amount or the switching value of two kinds of signals (gas signal and electrical signal).When system is in the analog amount adjusting, positioning work piece is accepted external command signal, and cooperate with solenoid valve, positioning work piece output relevant pressure is to cylinder, make piston displacement promote swing arm (12) and convert 0 ° of-70 ° of corner to, swing arm (12) drives 0 °-70 ° of valve plate (5) rotations, and valve plate (5) rotation drives positioning work piece cam (20) by the mechanical structure feedback again and obtains balance.When system need open or during quick closing valve soon, final controlling element is accepted the switching value signal, also cooperate with solenoid valve, connect corresponding loop, qi of chong channel ascending adversely or exhaust fast, reach and open soon or the quick closing valve purpose, the utility model also is equipped with hand-hydraulic mechanism, and is provided with switching valve and combination Pilot operated check valve, and the combination Pilot operated check valve is made up of two one-way valves, and two connecting legs are arranged respectively with they unilaterally connecteds, can reach hydraulic system and have self-lock ability, when pressure system is malfunctioning, promptly available hand-operated hydraulic press structure, therefore, the work of actuator is fool proof reliable.
The utility model is compared with known technology, have various advantages, can with pneumatic, the supporting use of DDZ, it is indispensable kind in the automation control, be used for control gaseous, liquid, steam and contain the fluid flow of suspended particulate, can also be widely used in dense slurry fluid simultaneously.The utility model carries out disjunctor with cylinder, oil cylinder, positioning work piece, valve body to be installed, simple in structure, precision is high, flow resistance is few, and the speed of opening or closing is fast, snap switch amount gamut time 1-4 second, hydraulic system has self-lock ability, and is safe and reliable, and can adapt to two kinds of handshaking uses.
The utility model has following accompanying drawing:
Fig. 1 is a structural drawing
Fig. 2 is the sectional view that piston rod and swing arm link
Fig. 3 is a system schematic
Fig. 4 is the enlarged view of A part among Fig. 1
Accompanying drawing has been represented structural principle of the present utility model, describes embodiment below in conjunction with accompanying drawing:
When system is in analog amount, positioning work piece (4) work, solenoid valve (17) is opened, solenoid valve (16) cuts out, loop a, c communicate, and b, c are obstructed, and hydraulically balanced valve (8) is opened, gas equilibrium valve (9) cuts out, the pneumatic actuator acknowledge(ment) signal makes the cylinder up and down of cylinder (2) cause that pressure reduction produces displacement, promotes piston motion, piston rod (10) drives swing arm (12) and converts 0 ° of-70 ° of corner to, and the valve rotation drives positioning work piece cam (20) by the mechanical structure feedback and obtains balance.
When system need open or during quick closing valve, pneumatic actuator is accepted the switching value signal soon, solenoid valve (16) is opened, and solenoid valve (17) cuts out, and loop b, c communicate, and fast towards exhaust, reach and open soon or the quick closing valve purpose.
When control signal is out of control, adopt the hand-hydraulic system, at first close oil cylinder (1) and go up hydraulically balanced valve (8), after open cylinder (2) and go up gas equilibrium valve (9), and note the switching pointer position of switching valve (15), (upper cylinder half has pressure) need valve closing must switch to down cylinder position with switching valve (15) as manually to valve wide open the time.Be provided with combination Pilot operated check valve (13) in this hydraulic system, because two one-way valves are with two pipeline unilaterally connecteds, it makes hydraulic system have self-lock ability, manually can both obtain desirable work condition state to any position.
