Abstract
The utility model discloses a novel electric flow valve. The novel electric flow valve comprises a motor (1), a valve body (2) and the like, and is characterized in that: a water outlet (13) is connected with a water inlet (12) in a through way; a valve plug is a rotary butterfly valve plug (8) with high tightness; the motor (1) controls a valve rod (6) through a phasing gear to dive to the butterfly valve plug (8) to rotate; and a flow monitor (9) and a temperature sensor (10) are arranged inside and outside the valve body (2), and are connected to a controller (11) on the motor (1) to realize accurate control. The utility model has the advantages that: the valve body (2) is simple in system construction, and the novel electric flow valve does not leak, and has long service life. The novel electric flow valve is high in accuracy, reacts sensitively, is easy to control, and is reliable in working performance during work. The opening and closing time can be controlled by a singlechip, and the novel electric flow valve is directly controlled by calculation, the aim that the novel electric flow valve has a mechanical structure, but does not have mechanical failure is fulfilled, 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 flow, 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; Be made up of motor (1), valve body (2), valve gap (3), valve disc (4), valve seat (5), valve rod (6), stuffing box gland (7), butterfly 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, the spool in the valve body is chosen the strong rotatable butterfly spool of seal; Motor drives the rotation of butterfly spool through one group of covert gear control valve bar; Motor is provided with flow monitor and temperature inductor respectively inside and outside valve body, it is connected in the controller on the motor, realizes according to external environment condition flow accurately being controlled.
The beneficial effect of the utility model is: 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 butterfly 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.
