Solar energy water-fullness self-turn-off gate valve

Abstract

The invention provides a solar energy water-fullness self-turn-off gate valve, which solves the defects of the prior manual water-filling solar energy heater that one personnel is necessary to monitor the prior solar energy heater when filling the water into the heater because no water-fullness self-turn-off device is set in the heater. A gate chamber is set in the solar energy water tank to obstruct the main inlet-and-outlet hose and the water is directly supplied and an inlet-and-outlet hose of the water tank is communicated with an exhaust pipe and a gate valve connected with a float tank is set in the gate chamber. When the water is used, the water pressure of the main inlet-and-outlet hose is reduced and the gate valve is driven to shift downwards and then opened and the float tank loses buoyancy after the water level drops to the bottom and the gate valve sinks due to own gravity and the passage is kept; when the heater is filled with water, the float buoyancy lifts the gate valve until closed, when the water-filling is stopped. The main feature of the gate valve is that the gate valve is automatically turned off and on using the water buoyancy and differential water pressure. The gate valve is automatically turned off and on, a personnel for monitoring the heater is not necessary and the water waste is prevented. The gate valve has simple structure and is conveniently mounted and maintained.

Description

Technical field: [0001] The invention solves the inconvenience caused by personnel monitoring when manually filling the solar water heater. Background technique: [0002] The existing manual water filling solar water heater does not have a self-closing device when the water is full, and if the water is full and forgets to turn it off, it will cause loss and waste. However, the cost of the electromagnetic control water filling device is relatively high, and it is difficult to maintain at home. Invention content: [0003] A self-closing gate valve is added to the solar water tank to solve the inconvenience caused by the need for personnel to monitor the solar water heater manually. [0004] Add a gate valve chamber to cut off the direct water supply from the main inlet and outlet pipes, and connect the inlet and outlet pipes and exhaust pipes of the water tank. Drive the gate valve to move down, the gate valve opens, the buoy loses its buoyancy after the water level drops t...
