and a flow velocity sensor is arranged on the other side of the flow channel and is electrically connected with the control box.
Furthermore, the bottom of the valve core is a valve core end part, the valve core end part is hemispherical or inverted conical, and the maximum diameter of the valve core end part is matched with a reserved transverse gap of the flow channel.
Furthermore, an anti-seepage rubber mat is arranged at the bottom of the valve channel.
To sum up, the utility model discloses compare the beneficial effect who has in traditional technical means and be:
1. the utility model discloses can realize the cut-off of valve, improve in the past can produce the problem of leaking after flow control valve closes.
2. Utility model's the steerable flow size of flow control valve, detectable velocity of flow is fast, effectively monitors velocity of flow.
Drawings
The foregoing and other objects, features, and advantages of the invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1. the anti-seepage rubber gasket comprises a first cylinder, 2, a second cylinder, 3, a first connecting rod, 4, a connecting frame, 5, a control box, 6, a valve core, 7, a valve core end part, 8, a flow channel, 9, a second connecting rod, 10, a transverse gap, 11, a valve, 12, a valve channel and 13.
Detailed Description
In the following, the preferred embodiments of the present invention will be explained, and various changes and modifications can be made by workers without departing from the technical spirit of the present invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
The invention will be further described with reference to the following description of the drawings:
referring to fig. 1, the flow control valve includes a valve core 6, a flow channel 8, a cylinder, a connection frame 4 and a control box 5, the cylinder includes a first cylinder 1 and a second cylinder 2, the first cylinder 1 is fixedly connected with the valve core 6 in the flow channel 8 through a first connecting rod 3 which is movable up and down in the connection frame 4, the control box 5 is fixedly arranged on the side surface of the connection frame 4, and the control box 5 is electrically connected with the first cylinder 1. The bottom of the valve core 6 is a valve core end part 7, the valve core end part 7 is hemispherical or inverted conical, and the maximum diameter of the valve core end part 7 is matched with a transverse gap 10 reserved in the flow channel 8.
In the above flow rate regulating valve, the first cylinder 1 is mainly responsible for controlling the up-and-down movement of the valve core 6 in the flow rate channel 8, the end portion 7 of the valve core also moves up and down along with the valve core 6, and the valve core end portion 7 is hemispherical or inverted conical, so that the flow rate can be controlled by controlling the up-and-down movement of the valve core 6. The fluid flows through the gap between the end 7 of the valve core and the flow channel 8, the gap gradually increases with the upward movement of the valve core 6, and conversely, the gap gradually decreases, and the flow rate also increases or decreases.
A valve channel 12 perpendicular to the flow channel 8 is arranged on one side of the flow channel 8, the top end of the valve channel 12 is fixedly connected with a second cylinder 2, the bottom of the second cylinder 2 is connected with a valve 11 in the valve channel 12 through a second connecting rod 9, and the second cylinder 2 is electrically connected with the control box 5; and a flow velocity sensor is arranged on the other side of the flow channel 8 and is electrically connected with the control box 5.
The control box 5 is internally provided with a circuit board for controlling the second cylinder 2 to pull the valve 11 to open and close up and down through the second connecting rod 9, so that the problem of leakage still occurring after the flow regulating valve is turned off is avoided. Meanwhile, the flow velocity sensor can monitor the flow, detect whether leakage exists after the valve 11 is closed, and feed a new signal back to the control box 5 and the upper computer to make judgment and response in time.
The bottom of the valve channel 12 is provided with an anti-leakage rubber mat 13, and the anti-leakage rubber mat 13 further enhances the anti-leakage function and prevents part of the fluid from permeating into the flow channel 8 from the valve 11.
