Description

Hydraulic suction closed solar water heater automatic water heater

technical field

The utility model relates to an automatic water supply device with an overflow pressure bottle, a water inlet controller and a flat pressure suction assembly, in particular to an automatic water supply device for a solar water heater. the

Background technique

At present, there are two main types of automatic water supply devices for solar water heaters: one is the inductive automatic water supply device. Realize automatic control of water supply. One type is a mechanical automatic water supply device. The working principle is to use the buoyancy of the float or overflow momentum or overflow gravity to push (pull) related devices to close the water valve to realize automatic control of water supply. Defects and deficiencies in the automatic water supply device of inductive and mechanical solar water heaters. Inductive type: 1. Prone to failure. After the sensor is immersed in water, it is easy to generate scale or oxidize, causing related components to fail, and the electronic components of the environmental humidity control box are easily damaged; 2. The cost is high. The cost of an automatic water supply device for an inductive solar water heater is generally several times that of a mechanical solar water heater automatic water supply device; 3. The installation is complicated. It is necessary to install lines and related devices indoors and outdoors; 4. Potential safety hazards. It is dangerous to use it in a humid environment due to leakage of electricity. Mechanical: 1. High failure rate. Mechanical switch devices mainly adopt valve-type, plug-type or piston-type structures. After working in water, fouling will lead to tight closure and water leakage, and the increased friction of valves, bolts, rods, pistons and movable sealing rings will not be able to increase the friction. 2. Valves, bolts, pistons and other parts need to be leak-proof, and the processing accuracy is high; 3. Some changes in pipelines and solar water heater storage tanks are required during installation. the

Contents of the invention

What the utility model aims to solve is to provide a brand-new automatic water feeder for solar water heaters aiming at the deficiencies in the prior art. the

In order to solve the above technical problems, the utility model hydraulic suction closed solar water heater automatic water heater includes: overflow pressure bottle, pressure tank, control screw, return spring, water inlet control taper, telescopic rubber hose, pressure suction plate, leak-proof Gaskets and other components. One end of the control screw is connected to the fixed plate, the fixed plate passes through the return spring, the control screw passes through the middle hole of the middle cover to connect the sealing telescopic rubber sleeve, and the other end is connected to the suction plate and the leak-proof rubber pad. Pressure tank cover, pressure tank. the

In the hydraulic suction-closed automatic water heater for solar water heaters, the central part of the bottom of the pressure tank is provided with a cylindrical suction port protruding from the bottom, and the lower part of the suction port is a water outlet. the

In the hydraulic suction-closed automatic water heater for solar water heaters, a water inlet is provided on the lower side of the pressure tank, and the water inlet is provided with a conical mouth and a water inlet control cone composed of a vertical groove on the conical surface and a decompression spring. controller. the

In the hydraulic suction-closed automatic water heater for solar water heaters, a telescopic rubber hose is connected between the bottom of the overflow pressure bottle and the bottom of the bottle, and small holes for draining water are provided at the bottom of the bottle and the upper side of the pressure tank. the

The working principle of the utility model: open the tap water pipeline valve, the cold water enters the pressure tank from the water inlet equipped with the water inlet controller, and enters the solar water heater water storage tank from the water outlet, and when the water is full, the overflow water flows into the utility model from the overflow port of the solar water heater water storage tank In the overflow water heavy pressure bottle, when the gravity of the overflow water in the overflow water heavy pressure bottle is greater than the elastic force of the return spring at the bottom of the bottle, press down the control screw to go down, and the lower end of the control screw presses the suction plate against the pressure suction port, and the suction plate in the pressure tank is pressed under the action of the liquid pressure Close to the pressure suction port (the water inlet pressure is greater than the sum of the water pressure of the solar water heater storage tank and the spring force of the return spring), the water inlet stops, and the automatic closing action is completed. The overflow water in the heavy pressure bottle flows out slowly from the water discharge small hole, and the pressure gradually loses. When using the hot water in the storage tank of the solar water heater, close the pipeline valve, the upward water pressure disappears, turn on the faucet, the water pressure of the storage tank of the solar water heater and the elastic force of the return spring push the control screw upward at the same time, the pressure suction plate bounces off the suction port, and the hot water goes downward. the

(The function of the water inlet controller of the utility model: to prevent the water inlet pressure from being too high, the flow velocity around the pressure suction plate is too fast, the pressure is unbalanced, and the pressure suction plate is disturbed, so that the pressure suction plate is not tightly attached to the suction pressure suction port. The utility model enters Water controller principle: the higher the water inlet pressure, the water inlet control cone connected to the decompression spring will be pushed closer to the tapered mouth, the area of the water inlet will be reduced, the water intake will be reduced, and the pressure will drop. The water inlet control cone will The vertical groove on the surface is to ensure that when the water inlet control cone and the cone mouth are completely pressed together, there is still a certain water inlet area for water to enter.) 

Compared with other automatic water supply devices for solar water heaters, the utility model has the following advantages:

1. Reliable operation. The closing device of the utility model is constructed using the principle of liquid pressure, and the suction action between the suction plate and the suction port is without friction and moment, and has good stability. And the fouling will not affect the device. the

2. Easy to install. The utility model can realize installation without changing the pipeline and the solar water heater, and simplifies the double pipes of upper and lower water and overflow water into a single pipe. When connecting, the utility model only needs to be vertically fixed on the overflow port of the solar water heater storage tank, the water inlet is docked with the upper and lower water pipes, and the water outlet is docked with the upper and lower water outlets of the solar water heater storage tank. the

3. The parts of the utility model do not require high precision, are easy to process and assemble, have low cost, and have a long service life. the

Below in conjunction with accompanying drawing and embodiment the utility model is further described. the
