Remote control floating ball valve device with protection and automatic control of water inlet flow

Abstract

The invention discloses a remote control floating ball valve device with protection and automatic control of a water inlet flow. The device comprises a motor speed reducing mechanism, a switch power supply, a single-chip module, a potentiometer, a driving gear, a driven gear, a water pressure sensor and an outer shell; the driven gear is mounted at the upper end of the potentiometer; the potentiometer and the motor speed reducing mechanism are mounted in the outer shell; the driving gear is mounted at the middle part of a power output shaft of the motor speed reducing mechanism; a flange plateon an output power shaft of the motor speed reducing mechanism is connected with a flange plate at the front end of an adjusting valve rod of a needle valve mechanism; the outer shell is mounted at the front end of the needle valve mechanism; an open hole with an internal thread is formed in the upper part of a water inlet end of a remote control floating ball valve body; a connecting pipe is screwed in the open hole; one end of the connecting hose is inserted in a connecting pipe, and the other end of the connecting hose is inserted in an air pressure input pipe of a water pressure switch pressure sensor; and the motor speed reducing mechanism, the switch power supply, the single-chip module, the potentiometer and the water pressure sensor are connected by leads. The device can protect the water pressure of a pipe network.

Description

technical field [0001] The invention relates to the field of valves, in particular to a remote control floating ball valve device with protection and automatic control of water flow. Background technique [0002] The remote control float valve is a valve widely used to control the liquid level at a certain height. When working, it receives the buoyancy of the liquid through its own supporting float, and then under the action of the relevant mechanism, it controls the input or cut-off of the input liquid on the branch. When the liquid level is low, the internal liquid inlet valve core of the remote control float valve is opened, so that the liquid flows out through the liquid inlet port, the opened valve core, and the liquid outlet end of the remote control float valve. The core is closed, so that the liquid no longer enters the interior of the remote control float valve, so that the liquid in the container can be kept at an appropriate height; Under the action of the intern...

Problems solved by technology

When the secondary water supply system is working, it is connected to the municipal water pipe network. When the water level in the water tank is not at the highest level, the internal valve core will always be open to inject water into the water tank. It cannot be used in the municipal water pipe. When the network water pressure is lower than a certain range, reduce the input tap water flow (in actual use, the remote control float valve used in the secondary water supply system, the adjustment handle of the needle valve mechanism is pre-adjusted in place, so that the remote control float valve is generally maintained when entering water. In the state of large flow water inflow, the adjustment handle of the needle valve mechanism cannot be adjusted too small, too small adjustment will lead to excessive water consumption, and the water intake of the remote control float valve is too small to meet the water demand of users), so, if the municipal tap water pipe network If the water pressure drops to a certain value, since the spool of the valve is always in the state of high-flow water intake, it will aggravate the drop in water pressure in the municipal tap water pipe network, causing other users to not be able to use water normally; in fact, due to the large water storage capacity in the water tank If the water pressure of the municipal pipe network is too low for a period of time, no water replenishment or small flow replenishment will be carried out, which will not affect the normal water consumption of users who are supplied with water by the booster pump water supply equipment for a period of time
