Abstract
The utility model relates to a pneumatic actuator capable of being used on a valve and opening or closing the valve, and discloses an electro-hydraulic linkage actuating mechanism. The scheme includes that the electro-hydraulic linkage actuating mechanism is characterized by comprising a motor, an oil tank, an oil cylinder and a control and actuating device, the control and actuating device consists of an oil way manifold block, a hydraulic lock, a pressure regulating valve and an electromagnetic reversing valve, a coupler, a one-way gear pump and a high-pressure oil filter are sequentially arranged in the oil tank, an output shaft of the motor is connected onto the coupler, the coupler is connected with the one-way gear pump, and one end of the high-pressure oil filter is connected onto the one-way gear pump while the other end of the high-pressure oil filter is disposed on the inner lateral wall of the oil tank. By the aid of the scheme, the electro-hydraulic linkage actuating mechanism overcomes shortcomings of the prior art, and is a novel electro-hydraulic linkage executing mechanism adopting a piston principle and a combined electric and hydraulic mode to realize opening or closing of a valve.
Description
Technical field
The utility model relates to a kind of pneumatic actuator of that use and the straight journey that can open or close valve on valve.
Background technique
At present, the operation that valve is opened or closed is following two kinds of situations basically: 1, manually-operable, and this mode is cumbersome, and particularly large-scale valve operation requires great effort very much, time-consuming; 2, motor directly drives operation, and this mode is more convenient, but very high to the requirement of motor, and breaks down easily, so ideal that neither be very.
Summary of the invention
The utility model overcomes the deficiency that prior art exists, and a kind of piston principle of utilizing is provided, and adopts the mode electronic and associating of surging to realize valve open or the novel electric liquid of the closing actuator that links.
For achieving the above object, the utility model adopts following scheme: a kind of electric liquid interlock actuator, it is characterized in that: include motor, fuel tank, oil cylinder and control actuating device, described control actuating device includes oil circuit integrated package, hydraulic lock, pressure regulator valve and solenoid directional control valve, be disposed with coupling, ratchet pump and high pressure filter in the described fuel tank, the output shaft of motor is connected on the coupling, coupling is connected with the ratchet pump, and high pressure filter one end is connected that the other end is arranged on the madial wall of fuel tank on the ratchet pump.
By adopting such scheme, the electric liquid interlock actuator that this is used on the valve is simple in structure, and operation is convenient, and cost is low, motor is required low, advantages such as long service life.
Further setting of the present utility model is: be set with substrate on the described fuel tank outer wall, oil circuit integrated package, hydraulic lock, pressure regulator valve and solenoid directional control valve are fixed on the substrate; Two hydraulic fluid ports on the oil circuit integrated package link to each other by high-pressure oil pipe with two hydraulic fluid ports on the oil cylinder.
Below in conjunction with accompanying drawing the utility model is described further.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is the utility model embodiment's a schematic diagram.
Embodiment
As depicted in figs. 1 and 2, a kind of electric liquid interlock actuator, include motor 1, fuel tank 2, oil cylinder 3 and control actuating device 4, described control actuating device 4 includes oil circuit integrated package 41, hydraulic lock 43, pressure regulator valve 42 and solenoid directional control valve 44, be disposed with coupling 5, ratchet pump 6 and high pressure filter 7 in the described fuel tank 2, the output shaft of motor 1 is connected on the coupling 5, coupling 5 is connected with ratchet pump 6, and high pressure filter 7 one ends are connected that the other end is arranged on the madial wall of fuel tank 2 on the ratchet pump 6.Adopt such scheme, the electric liquid interlock actuator that this is used on the valve is simple in structure, and operation is convenient, and cost is low, motor is required low, advantages such as long service life.
In the utility model embodiment, be set with substrate 8 on described fuel tank 2 outer walls, oil circuit integrated package 41, hydraulic lock 43, pressure regulator valve 42 and solenoid directional control valve 44 are fixed on the substrate 8; Two hydraulic fluid ports on the oil circuit integrated package 41 link to each other by high-pressure oil pipe 9 with two hydraulic fluid ports on the oil cylinder 3.
The utility model embodiment's working principle: as shown in Figure 3, motor 1 starts, ratchet pump 6 is from fuel tank 2 oil suctions, high pressure oil is squeezed into solenoid directional control valve 44 by oil purifier 7, if 1DT and 2DT be no electric circuit, then solenoid directional control valve 44 is in meta, and this moment, high pressure oil was by pressure regulator valve 42 oil sump tanks 2; When 1DT charged, high pressure oil is by intersecting oil circuit, right one-way valve, Double throttle check valve 10 right one-way valves and high-pressure oil pipe 9 by hydraulic lock 43 enter oil cylinder 3 back cavities, meanwhile, hydraulic lock 43 internal control oil circuits are opened the left side one-way valve, oil cylinder 3 ante-chambers are communicated with fuel tank 2, and piston rod stretches out; Otherwise, but 2DT is when charged, and a telescopic process is finished in the piston rod withdrawal, and no matter what position piston is parked in, and the chamber, front and back of oil cylinder 3 can both keep-up pressure and lock.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
