DETAILED DESCRIPTION
[0023] In order to make the skilled in the art better understand the technical scheme of the utility model, the utility model is described in detail below in conjunction with the drawings, and the description of this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the utility model.
[0024] The utility model discloses a valve, its mainly includes the frame 3 that constitutes by the inner transverse board 1 and the outer frame 2, the hydraulic cylinder 7 of fixed mounting in the inside frame 3, the slide connection of the shutter 19 with the track 6, the track 6 that constitutes by the recess 5 of setting in the inner wall of outer frame 2 and the through groove 4 in the middle part of inner transverse board 1, the shutter 19 is fixedly connected with the hydraulic cylinder 7, through the hydraulic cylinder 7 drive shutter 19 along track 6 sliding, realize the effective opening and closing of shutter 19, thereby can control the opening and closing of material mouth, control the flow of material, and simultaneously, the inner transverse board 1 divides the frame 3 inside into shutter body closed area 8 and shutter body open area 9, when material discharges, the hydraulic cylinder 7 drive shutter 19 slides to shutter body open area 9, conversely, when not discharging material, the hydraulic cylinder 7 drive shutter 19 slides to shutter body closed area 8, the above is the introduction of the valve of present.
[0025] From the above, the existing valve has the following defects when in use, namely, in the unexpected situation, such as power failure or high temperature condition causes hydraulic system failure (when power failure, the hydraulic cylinder 7 lacks the hydraulic pump driven by power to provide the pressure of hydraulic oil, when the hydraulic system fails, such as the control pressure of hydraulic system is lower than the normal value, the throttling resistance in control pipeline is too large, the valve core is stuck or the valve hole is blocked, etc.), the hydraulic cylinder 7 cannot work normally, the shutter 19 cannot close in time, causing material loss, which not only wastes resources, but also may cause pollution to the production environment, and even causes safety accidents.
[0026] Based on the above problems, the utility model adopts the following improvement mode to solve, such as Figures 1-9As shown, a quick closing gate valve is provided, which is based on the prior art. An electromagnet 10 is fixedly connected to the end of a hydraulic cylinder 7. A first permanent magnet 11 is connected to one end of the gate 19 near the gate body opening area 9. The electromagnet 10 and the first permanent magnet 11 are attracted to each other under the condition of power supply, thereby realizing the stable adsorption connection between the hydraulic cylinder 7 and the gate 19. When the gate 19 is driven by the hydraulic cylinder 7 to be located at the gate body opening area 9, the gate 19 stores potential energy. When the electromagnet 10 is powered off, the gate 19 is separated from the hydraulic cylinder 7 to release the potential energy. The released potential energy is used to drive the gate 19 of the gate body opening area 9 to the gate body closing area 8, thereby realizing the timely closing of the discharge port to prevent material loss. In addition, a controller is further provided. The controller can control the strength of the magnetism of the electromagnet 10 by controlling the current size of the electromagnet 10. For the gate 19 with large volume and heavy weight, the electromagnet 10 needs strong magnetism, and the current needs to be large. For the gate 19 with small volume and small weight, the electromagnet 10 needs weak magnetism, and the current needs to be small. At the same time, the controller can also monitor the working state of the hydraulic cylinder 7 to determine whether the electromagnet 10 and the first permanent magnet 11 need to be disconnected. For example, the pressure sensor signal of the hydraulic system can be monitored, the flow of the oil inlet and outlet of the hydraulic cylinder 7 can be monitored, the travel position of the hydraulic cylinder 7 can be monitored in real time, for the electric hydraulic cylinder 7 or the hydraulic cylinder 7 with an electrical control element, the controller can monitor the related electrical signals (such as motor current, solenoid valve state, etc.), to determine the working state of the hydraulic cylinder 7, thereby facilitating the timely and quick closing of the gate 19 in unexpected situations. The principle of the controller monitoring the hydraulic cylinder 7 belongs to the prior art, and will not be described in detail here.
[0027] Further, as Figures 5-6As shown, the potential energy stored by the above-mentioned gate 19 is divided into two cases according to the use state of the valve, wherein for the valve used in the transverse state, a spring 12 can be installed in the gate body open area 9, one end of the spring 12 is fixedly connected with the gate 19 and the crossbar 20 inside the frame 3 in the gate body open area 9, at this time the potential energy stored by the gate 19 is elastic potential energy, when the gate 19 is in the gate body open area 9, the gate 19 compresses the spring 12, thereby storing elastic potential energy, when the gate 19 is separated from the hydraulic cylinder 7, the spring 12 restores the deformation to release the elastic potential energy, and drives the gate 19 to the gate body closed area 8, because the spring 12 has elastic ability, it is easy to change direction during compression and reset, a guide rod 15 is installed inside the spring 12 to guide the spring 12, the guide rod 15 can be an integral long rod (not shown in the figure), the guide rod 15 is in sliding connection with the frame 3, when the hydraulic cylinder 7 is normally used, the guide rod 15 is driven to slide along the frame 3 to adapt to the extension or compression of the spring 12, and the guide rod 15 can also be separately arranged, such as Figures 5-6 As shown, the guide rod 15 includes a fixed part 16 and a movable part 17 in sliding connection with the fixed part 16, a sliding groove 18 with the same length as the movable part 17 is formed in the fixed part 16, one end of the movable part 17 close to the fixed part 16 extends into the sliding groove 18, in order to avoid the movable part 17 from sliding out of the fixed part 16, the length of the movable part 17 is set to be greater than the width of the gate body closed area 8, and one end of the fixed part 16 away from the movable part 17 is fixedly connected with the frame 3, one end of the movable part 17 away from the fixed part 16 is fixedly connected with the gate 19, when the hydraulic cylinder 7 drives the gate 19 in the gate body open area 9 to slide along the track 6 to the gate body closed area 8, the gate 19 drives the movable part 17 to slide along the sliding groove 18, thereby unfolding the guide rod 15 and driving the spring 12 to reset along the guide rod 15, when the gate 19 is completely in the gate body closed area 8, one end of the movable part 17 close to the fixed part 16 is still in the sliding groove 18.
[0028] Further, as shown in Figures 7-9 In addition, for the valve used in the vertical state, the potential energy of the above-mentioned gate 19 can also be gravitational potential energy, when the gate 19 is in the gate body open area 9, the gate 19 is at a higher position, storing gravitational potential energy, when the gate 19 is separated from the hydraulic cylinder 7, the gate 19 falls due to gravity, releasing the gravitational potential energy, and falling to the gate body closed area 8 to achieve the closing of the material port, as shown in Figure 9As shown, for the valve in the vertical state, the potential energy of the shutter 19 can also be the combined gravitational potential energy and elastic potential energy. When the shutter 19 is in the open area 9 of the shutter body, the shutter 19 is in a higher position, the spring 12 is compressed, and the gravitational potential energy and the elastic potential energy are stored. When the shutter 19 is separated from the hydraulic cylinder 7, the shutter 19 falls due to gravity, the spring 12 resets, the gravitational potential energy and the elastic potential energy are released, the shutter 19 falls to the closed area 8 of the shutter body, the material port is closed, and the speed of the shutter 19 falling is further accelerated.
[0029] Further, as shown, Figures 2-6 For the valve in the horizontal state, when the spring 12 drives the shutter 19 to slide to the closed area 8 of the shutter body by releasing the elastic potential energy, in order to avoid the reciprocating motion of the shutter 19 under the elastic action of the spring 12, which affects the rapid closing of the shutter 19, a second permanent magnet 13 is fixedly installed at one end of the shutter 19 away from the first permanent magnet 11, a third permanent magnet 14 is installed inside the track 6 and cooperates with the second permanent magnet 13, and when the shutter 19 slides to the closed area 8 of the shutter body, the third permanent magnet 14 and the second permanent magnet 13 are attracted to each other by magnetic force within a certain distance, so that the shutter 19 is rapidly closed.
