Abstract
The utility model relates to an electric speed regulation butterfly valve, comprising an electric device, a driving device, a control device and a butterfly valve. The motor of the electric device uses two-speed motor. After a logic controller is installed in the control box of the control device, the utility model can satisfy that the butterfly valve has two stages closing valve speed of high speed and slow speed, and the switching speed of the regulation butterfly valve to prevent the water hammer breaking the pump unit and the pipe network system, and the utility model ensures normal operation when medium is conveyed.
Description
The utility model relates to valve, particularly relates to the butterfly valve of electronic speed governing.
During water pump assembly pipe network system water delivery operation, during as if chance power failure suddenly or water pump assembly stall, the pressure in the pipe network raises, and causes backwater to the impact failure of pipe network water pump assembly.
In order to protect water pump assembly and pipe network system safe operation, a kind of regulable speed type electric butterfly valve has adopted variable-frequency control technique, but during the low speed throttle down, still can not effectively eliminate or suppress the destruction of water hammer to water pump assembly and pipe network.Another kind of electronic quick opening valve, its unlatching, throttle down speed are quick, but to inhibition ability shortcoming, the very flexible of water hammer.
The purpose of this utility model: provide a kind of speed governing and quick closing valve to close the butterfly valve of two stages pass valves slowly, make it have the function of gate valve and safety check, and effectively preventing the destruction of water hammer to the water pump assembly pipe network system, assurance water pump assembly and pipe network system are moved reliably.
The technical solution of the utility model realizes as follows:
The utility model comprises control gear, Electric actuator, transmission device, butterfly valve, the motor of its Electric actuator adopts double-speed motor, when making the water pump assembly stall, when butterfly valve cuts out, have quick closing valve and close the speed in two stages slowly, in the control box of control gear, be provided with a logic controller.
Its logic controller is PLC or impulse timer, and the start-stop frequency of control double speed Electric actuator is regulated butterfly switch speed, makes butterfly valve have the function of speed governing.
Advantage of the present utility model is as follows:
The utlity model has fast and the pass valve speed in two stages at a slow speed, and control system can satisfy the requirement of adjusting butterfly switch speed, effectively prevent or suppress the destruction of water hammer water pump assembly and pipe network system.Its manufacturing and maintenance are simple, with low cost.
Embodiment in conjunction with the accompanying drawings, the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Fig. 2 is the controlling party block diagram among Fig. 1.
Among Fig. 1: double-speed motor (1) is connected transmission device (2) and is connected with butterfly valve (3) with transmission device (2), and logic controller (burst length dimension electrical equipment) (5) is in the control box (4) of control gear.
Among Fig. 2: control power supply------logic controller---output signal---Electric actuator---transmission device---valve of going into signal.
Input signal, logic controller, output signal, double-speed motor and control power supply link; When the water pump assembly pipe network system is moved, need quick closing valve, close slowly and various speed is opened or when closing butterfly valve, the frequency of the different situations that input signal is selected for use is input to logic controller, logic controller is defeated by output signal according to input signal, the frequency drives transmission device that Electric actuator receives according to output signal, the butterfly valve action.
Claims (2)
1. an electronic speed-regulating butterfly valve comprises Electric actuator, transmission device (2), control gear, butterfly valve (3), it is characterized in that: the motor of its Electric actuator is double-speed motor (1), is provided with a logic controller (5) in the control box (4) of control gear.
2. electronic speed-regulating butterfly valve according to claim 1 is characterized in that: logic controller (5) is PLC or impulse timer.
