Abstract

The invention relates to an intelligent control device suitable for various water valves. The intelligent control device comprises a water valve body, a switching power supply, the intelligent controldevice is further provided with a first control circuit, a second control circuit, a water level detection mechanism and a valve element adjusting mechanism; the water level detection mechanism comprises an outer cylinder, an upper inner cylinder, a sliding adjustable resistor, a floater and a linkage rod which are installed together; the valve element adjusting mechanism comprises a motor reducing mechanism, an upper cylinder, a lower cylinder, a lower magnet, an upper magnet and a follow-up rod which are installed together; and the water level detection mechanism and the valve element adjusting mechanism are installed on the water valve body, and the switching power supply, the first control circuit and the second control circuit are installed in a component box and electrically connected with the sliding adjustable resistor and the motor reducing mechanism. According to the intelligent control device suitable for the various water valves, the intelligent control device is simple instructure, convenient to install, low in cost, wider in application range and good in universality, the water level height can be effectively monitored, the water amount is automatically controlled to be at the setting position, the fact that due to any reason, the water pressure is reduced so that water flow in a pipeline can be judged wrongly is avoided, and the accurate control of the liquid flow is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water valve supporting equipment, in particular to an intelligent control device suitable for various water valves. Background technique [0002] Water valve is a kind of equipment that is widely used in production and civil fields. It is mainly divided into gate valve, globe valve, throttle valve, butterfly valve, check valve, ball valve and so on. The regulating stem of water valves is generally divided into single-turn operation or multi-turn operation. For example, the regulating stem of a ball valve rotates left and right to close or open the valve core, and the control of the opening and closing degree of the valve core will not exceed 360 degrees; It is necessary to rotate the valve stem for multiple turns to realize the opening or closing of the valve core, and to realize the control of the opening and closing degree of the valve core. [0003] Due to the need for automatic flow control in many i...

Problems solved by technology

[0005] In order to overcome the existing control equipment for controlling the opening or closing of the water valve spool and the degree of opening and closing of the spool, due to the high cost due to the structure limitation, it can only work correspondingly to control a water valve that adjusts the rotation mode of the valve stem. It has versatility and application limitations, which will bring certain disadvantages to production and after-sales, and the inaccuracy of judging the flow in the pipeline according to the water pressure detection switch signal will affect the correct flow control. The present invention provides The structure is simple, easy to install, and low in cost. It can be directly used for water valves that adjust the one-turn rotation of the valve stem, and is also suitable for water valves that adjust the multi-turn rotation of the valve stem. It can meet various types of water valves as much as possible. Directly installed and used, the buoyancy of the water can effectively monitor the water level in the outlet pipe (that is, the water volume) in real time during the application, and automatically control the water volume at the set position, and will not cause any damage to the pipeline due to the decrease of the water pressure in the pipeline An intelligent control device suitable for various water valves, which effectively ensures the precise control of the liquid flow due to the wrong judgment of the internal water flow
