Abstract
The utility model discloses a ratio adjusting valve comprising a pressure sensor, a PLC, a three-position five-way double electric control electromagnetic valve, a butterfly valve, a potentiometer and a transmitter. The output end of the pressure sensor is connected with the input end of the PLC, the output end of the PLC is connected with the control end of the three-position five-way double electric control electromagnetic valve, and the three-position five-way double electric control electromagnetic valve is connected with a valve driving air cylinder of the butterfly valve; the potentiometer is in linked with a valve of the butterfly valve; and the potentiometer and the transmitter output valve position signals of the butterfly valve to the PLC. As the ratio adjusting valve adopts the three-position five-way double electric control electromagnetic valve to substitute the original three-position four-way electromagnetic valve, the cost of the apparatus is greatly saved; the self structure of the three-position five-way double electric control electromagnetic valve can effectively solve the problem of lower unit flow of compression air of a driving transmission actuator, so that the valve operation is more reliable; and meanwhile, the potentiometer is adopted to substitute the original conduction plastic which is easily abraded, so that the operation is more reliable.
Description
Technical field
The utility model relates to a kind of ratio adjusting valve.
Background technique
Ratio adjusting valve is owing to the size of control valve unlatching accurately, and its purposes is comparatively extensive, all can bring into play its effect in fields such as the energy, metallurgy, environmental protection, agriculturals.At present, ratio adjusting valve mostly is imported product, but because it has adopted the driver of the three position four-way electromagnetic valve of offshore company's manufacturing as butterfly valve on valve control device, its import price higher (price surpasses 200,000 RMB), and maintenance cycle is long.Because the structure of its three position four-way electromagnetic valve is limit, and it is lower to transmit the compressed-air actuated specific discharge that drives butterfly valve, the butterfly valve valve causes valve in time to open opening the moment moment of torsion deficiency of closed condition valve simultaneously.This intrinsic defect may cause PLC to detect the signal that puts in place less than valve opening in back 10 seconds of action, then judges the valve opening failure, and PLC also will change valve open failure processor over to, cause entire equipment out of service.Simultaneously because it has adopted conductive plastic to follow the output element that the butterfly valve valve motion is used as its valve position feedback signal, in actual use, because valve moves more in day-to-day operation, make that the conductive plastic wearing and tearing are very fast, cause PLC can accurately not receive valve position signal, cause the regulating valve position inaccurate.
The model utility content
Higher for solving existing ratio adjusting valve price, occur easily during operation that valve can't normally be opened and the valve location is prone to wrong technical problem, the utility model provides a kind of price lower, and the ratio adjusting valve of the switching value of stable and reliable operation control.
The scheme that the utility model solves the problems of the technologies described above is: a kind of ratio adjusting valve, comprise pressure transducer, PLC, actuating valve, butterfly valve and butterfly valve valve location feedback device, the output terminal of described pressure transducer communicates to connect the input end to PLC, the output terminal of described PLC communicates to connect the control end to actuating valve, described actuating valve is connected to the valve driving cylinder of butterfly valve, described butterfly valve valve location feedback device is connected to the valve of butterfly valve, the output terminal of variable resistor device communicates to connect the input end to PLC, and its described actuating valve is the two automatically controlled solenoid valves of three-position five-way.
Above-mentioned a kind of ratio adjusting valve, its described butterfly valve valve location feedback device is potentiometer and transmitter, the driving gear that the resistance adjustment rotating shaft of described potentiometer is connected with a joggle and is fixed to the rotatingshaft of butterfly valve valve by Positioning Gear, the shell of potentiometer fixes and does not rotate by being connected and fixed part, the input end of described transmitter is connected to the output terminal of potentiometer, and the output terminal of transmitter is connected to the input end of PLC.
Technique effect of the present utility model is, adopted the domestic general and automatically controlled solenoid valve of three-position five-way that price is lower as driving element, makes installation cost be saved greatly, by the original price that surpasses 200,000 yuan, drops to less than 10,000 yuan.Because the structure of the automatically controlled solenoid valve of three-position five-way self can effectively solve the lower problem of compressed-air actuated specific discharge that transmits actuate actuators, make the valve operation comparatively reliable.Adopt potentiometer to substitute original conductive plastic more easy to wear simultaneously, make operation more reliable.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a circuit block diagram of the present utility model;
Fig. 2 is a potentiometer scheme of installation of the present utility model.
Embodiment
Referring to Fig. 1, the pressure of the water level in the pressure transducer measuring cell, and the pressure simulation signal delivered to PLC, PLC receives the pressure simulation signal of 4-20mA, and provide control command and drive the automatically controlled solenoid valve of three-position five-way, the output terminal of solenoid valve is connected to the valve driving cylinder of butterfly valve again.The twin coil of solenoid valve not simultaneously electric, a coil gets and drives butterfly valve when electric and open valve, another coil gets electric throttle down, location valve during the twin coil dead electricity, so both can regulate butterfly valve valve and control its open degree.
Referring to Fig. 2, the butterfly valve valve is that open and close is rotated in the axle center with rotatingshaft (3), be fixed with driving gear (4) on its rotatingshaft (3), potentiometer (1) comes the sensing valve position by Positioning Gear (2) the engagement driving gear (4) in the resistance adjustment rotating shaft (6).When the butterfly valve valve event, rotatingshaft (3) rotates the resistance that changes potentiometer by the resistance adjustment rotating shaft (6) that gear-driven mode drives potentiometer (1), the potentiometer shell fixes by fixed block (6), do not rotate with resistance adjustment rotating shaft (6), the change in resistance of transmitter induced potential device (1) becomes send output corresponding 4-20ma electric current and send PLC to, PLC to receive the position that both can confirm valve opening after the feedback signal that transmitter transmits.
Claims (2)
1. ratio adjusting valve, comprise pressure transducer, PLC, actuating valve, butterfly valve and butterfly valve valve location feedback device, the output terminal of described pressure transducer communicates to connect the input end to PLC, the output terminal of described PLC communicates to connect the control end to actuating valve, described actuating valve is connected to the valve driving cylinder of butterfly valve, described butterfly valve valve location feedback device is connected to the valve of butterfly valve, the output terminal of butterfly valve valve location feedback device communicates to connect the input end to PLC, it is characterized in that described actuating valve is the two automatically controlled solenoid valves of three-position five-way.
2. a kind of ratio adjusting valve according to claim 1, it is characterized in that, described butterfly valve valve location feedback device is potentiometer (1) and transmitter, the driving gear (4) that the resistance adjustment rotating shaft (5) of described potentiometer (1) is connected with a joggle and is fixed to the rotatingshaft (3) of butterfly valve valve by Positioning Gear (2), the shell of potentiometer fixes and does not rotate by being connected and fixed part (6), the input end of described transmitter is connected to the output terminal of potentiometer (1), and the output terminal of transmitter is connected to the input end of PLC.
