Abstract
The utility model provides a novel electric regulating valve, comprising an electromotor (1), a valve body (2), etc., the electric regulating valve is characterized in that, a through connection is adopted for a water outlet (13) and a water inlet (12), a rotatable disc type valve core (8) with high sealing performance is selected for the valve core, the electromotor (1) drives the disc type valve core (8) to rotate via a phase-change gear control valve stem (6), a flow monitor (9) and a temperature inductor (10) are respectively disposed at the internal and the external of the valve body (2), the flow monitor (9) and the temperature inductor (10) are connected with a controller (11) on the electromotor (1), and precision control is realized. The valve body (2) system is advantaged by simple structure, no leakage, and long service lifetime. The novel electric regulating valve is advantaged by high precision during work, sensitive reaction, simple control, and reliable work performance. A one-chip microcomputer can be used to control on-off time, and control is directly completed via calculation, purpose of no mechanical fault despite of mechanical structure is reached, manpower is saved, and cost is reduced.
Description
Technical field
The utility model relates to a kind of modulating valve, relates in particular to a kind of electric modulating valve.
Background technique
Electric control valve is a kind of industrial automation control appliance, and it is controlled through the area of passage convection cell that changes valve.On commercial production, be widely used in control procedures such as control flow rate, temperature, pressure.Electric control valve generally is made up of several sections such as servoamplifier, electric operationg station, electric actuator and valves.The valve position signal that control signal that servoamplifier is sent automation control appliance and electric actuator are sent compares calculating, valve is carried out operations such as open and close through actuator.Not enough below present electric control valve ubiquity: system complex, whole system is made up of four independent parts; Precision is low, and the common product intrinsic error is 4 percent, and return difference can reach more than 3 percent, and the dead band can reach 3 percent; Weight is big, processed complex; Control signal is an analog amount, and directly control can not use a computer.
Summary of the invention
In order to solve the problems of the technologies described above; The utility model provides a kind of structure simpler; Available Single-chip Controlling, reliable operation, long service life, control accuracy height; The electric modulating valve that product weight is low is made up of motor (1), valve body (2), valve gap (3), valve disc (4), valve seat (5), valve rod (6), stuffing box gland (7), dish formula spool (8), flow monitor (9), temperature inductor (10), controller (11), water inlet (12), water outlet (13), it is characterized in that water outlet and water inlet adopt the through design that is connected; Spool in the valve body is chosen the strong rotatable dish formula spool of seal; Motor drives the rotation of dish formula spool through one group of covert gear control valve bar, and motor is provided with flow monitor and temperature inductor respectively inside and outside valve body, and it is connected in the controller on the motor.
The beneficial effect of the utility model is: the utility model valve system constitutes simple, does not have leakage, long service life.Its validity when work is high, is quick on the draw, and control is simple, reliable working performance.Available Single-chip Controlling switching time, use to calculate directly to accomplish and control, be the purpose that mechanical structure does not have mechanical fault though reach, saved manpower, reduced cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
According to shown in Figure 1, valve body (2) is provided with water inlet (12) and water outlet (13), and valve disc (4) is combined closely on above-mentioned valve body (2) by valve gap (3) and valve seat (5), and dish formula spool (8) is connected valve rod (6) lower end and drives it through valve rod (6) and rotatablely moves.Valve gap (3) inside is provided with the sealing configuration of being made up of stuffing box gland (7), has avoided the corrosion of valve rod (6).Valve rod (6) is provided with covert gear away from the other end of spool, forms covert gear train with the covert gear that is connected on motor (1) transmission shaft, has realized the function of covert driving.Water inlet (12) inside is provided with one group of flow detector (9) to fluid; When flow in the water inlet (12) is lower than or exceeds normal range of operation; To carry out the order adjustment to motor (1) through the controller (11) that is arranged on the motor (1), to recover the valve normal working.Equally, being arranged at the outside one group of temperature inductor (10) of valve, can be that standard is passed through controller (11) and motor (1) instructed change, the unmanned control of automation of finally realizing valve with the surrounding working environment temperature.
Claims (1)
1. electric modulating valve; Constitute by motor (1), valve body (2), valve gap (3), valve disc (4), valve seat (5), valve rod (6), stuffing box gland (7), dish formula spool (8), flow monitor (9), temperature inductor (10), controller (11), water inlet (12), water outlet (13); It is characterized in that water outlet (13) and water inlet (12) adopt the through design that is connected; Spool in the valve body (2) is chosen the strong rotatable dish formula spool (8) of seal; Flow monitor (9) and temperature inductor (10) are set inside and outside valve body (2) respectively, and are connected on the controller (11) of motor (1).
