Description

Technical Field

[0001] The utility model relates to the technical field of stop valves, in particular to a stop valve with automatic liquid volume control function. Background Art

[0002] A stop valve is a valve whose opening and closing part is a plug-shaped disc, whose sealing surface is a plane or a cone, and whose disc moves in a straight line along the center line of the valve seat.

[0003] The stop valve is mainly composed of a valve body, a valve stem, a valve disc, a packing, a valve cover and a bracket. Its working principle is to rely on the pressure of the valve stem to make the sealing surface of the valve disc fit closely with the sealing surface of the valve seat to prevent the flow of the medium.

[0004] When in use, the existing stop valve cannot automatically make corresponding adjustments according to the size of the liquid flow in the valve body, and thus cannot automatically control the flow of the liquid; therefore, in order to solve the above problem, a stop valve with automatic liquid flow control is proposed. Utility Model Content

A battery is installed on the upper valve cover, and the battery is electrically connected to the motor. When liquid flows into the valve body, the water flow sensor can detect the flow rate and flow of water, and transmit the sensed signal to the flow meter. The flow meter receives the signal and displays the flow value of the water body. The flow meter transmits the analyzed and measured flow value to the controller. When the detected flow is small, the controller starts the motor to work and rotates the gear. With the cooperation of the teeth, the valve stem drives the conical blocking block to move up, so that the opening can be enlarged, thereby expanding the flow of the liquid. When the detected flow is large, the controller starts the motor to work and rotates the gear. With the cooperation of the teeth, the valve stem drives the conical blocking block to move down, so that the opening can be smaller, thereby reducing the flow of the liquid, so that the corresponding adjustment can be automatically made according to the detected flow size, so that the flow of the liquid can be automatically controlled.

[0007] Preferably, a flow meter is installed on the valve body, a water flow sensor is installed on the inner wall of the valve body, the water flow sensor is connected to the flow meter via a data line, a controller is installed on the upper valve cover, the controller is connected to the motor via a data line, and the controller is connected to the flow meter via a data line. When using the device, by setting up the water flow sensor, the liquid flow can be monitored in real time, and by setting up the flow meter, the flow information sensed by the water flow sensor can be received and transmitted to the controller in time, so that the controller can control the operation of the motor in time.

[0008] The utility model is beneficial in that:

[0009] 1. When liquid flows into the valve body, the utility model can detect the flow rate and flow of water through the water flow sensor, and transmit the sensed signal to the flow meter. The flow meter receives the signal and displays the flow value of the water body. The flow meter transmits the analyzed and measured flow value to the controller. When the detected flow is small, the controller starts the motor to work, and the gear and the teeth cooperate to make the valve stem drive the conical blocking block to move up, so that the opening can be enlarged, thereby increasing the flow of liquid. When the detected flow is large, the controller starts the motor to work, and the gear and the teeth cooperate to make the valve stem drive the conical blocking block to move down, so that the opening can be smaller, thereby reducing the flow of liquid, so that the corresponding adjustment can be automatically made according to the detected flow, so that the flow of liquid can be automatically controlled;

[0010] 2. When the utility model is used, by setting a water flow sensor, the liquid flow can be monitored in real time. By setting a flow meter, the flow information sensed by the water flow sensor can be received and transmitted to the controller in time, so that the controller can control the motor operation in time.
