Abstract

The utility model relates to a novel automatic water level controller for a solar water heater, and discloses an automatic water level controller. The automatic water level controller consists of floater, a connecting rod, a valve plate and a controller body, and is characterized in that the floater is made of a pipe which is thin, has two sealed ends or is filled with materials with low density; the pipe can pass through an inner hole of a water inlet of a water tank of the solar water heater; the joint of a pipeline of the pipe is positioned on the external side; a short section of cylinder is arranged in the middle of the valve plate; and when the valve plate rises, the cylinder is inserted into the water inlet of the controller to reduce the water flowing speed, the normal rising of the valve plate is prevented from being influenced by the impact of the water flow on the valve plate when the valve plate is raised to the outer water inlet. The utility model has the advantages that the production cost of the similar products is reduced, the structure is convenient, and the installation is convenient.

Description

The solar water heater automatic water level controller

Technical field:

The utility model relates to a kind of novel solar water heater automatic controller for water level, and it can control the solar water heater water tank height of water level automatically, also can control water on the running water automatically to other water tower, water tank, pond etc.

Background technology:

More existing automatic controller for water level, are installed not too conveniently at the complex structure that has, and take the miscellaneous part position, and the result of use that has is not ideal, and the utilization of present technique has overcome above shortcoming.

Technology contents: the present technique purpose is to propose a kind of novel solar water heater automatic water level controller, be called for short controller later on, it is by float, connecting rod, valve block, the controller main body constitutes, described float be by one than thin slightly hollow of solar water heater water tank lower water inlet endoporus or in fill the little material of density pipe make, the pipe closed at both ends, require it to be immersed in the buoyancy that is subjected in the water greater than connecting rod, the total force of valve block and itself, described connecting rod is thinner, be that one section hard or soft material are made, as steel wire, its effect is to link float and valve block.Described valve block is made by broad round material, there is one section short cylinder its top centre, cylinder is thinner slightly than controller inner inlet hole, the cylinder upper end becomes tapered, be in controller inner inlet mouth center when being beneficial to the valve block come-up, when valve block upper end cylinder rose to controller outside water inlet at valve block, it inserted controller inner inlet mouth, reduce the water inlet flow velocity, help valve block and normally rise.Described controller main body be one cylindric, there is internal thread its upper end, less near middle part, upper end internal thread below endoporus be controller inner inlet mouth, has one to take over mouthful near the outside, control inner inlet mouth below, has internal thread, in order to the connection hot water pipeline.There is internal thread controller main body lower end, and is rotary with the plug of a band silk, leaks in order to block the lower end, and plug is used for opening the controller lower end, the loading and unloading valve block.

Description of drawings:

Fig. 1 is the utility model tangent plane schematic diagram

Fig. 2 is that the utility model is installed in the tangent plane schematic diagram on the solar water heater water tank

In the drawings: 1, be float; 2 is connecting rod; 3 is valve block; 4 is the controller main body; 5 is controller inner inlet mouth; 6, be that mouth is taken in the controller outside; 7 is the lower end internal sealing plug; 8 is plug; 9 is solar water heater water tank; 10 is solar water container lower end water inlet.

Specific implementation method and operation principle: open controller lower end plug earlier, valve block is taken off from connecting rod, again float is all inserted from water inlet, solar water heater water tank lower end with one one on connecting rod, then controller main body endoporus is passed connecting rod, the upper end internal sealing plug is screwed on the water inlet of solar water heater water tank lower end, loads onto valve block, plug at last.One end of hot water pipeline is connected on the water inlet of the controller outside, the other end connects on the solar energy mixing valve of bathroom, the solar energy mixing valve can be to water on the solar water heater water tank and draining, during last water, close the mixing valve drainage switch, open taps, running water flows to solar water heater water tank through hot water pipeline by controller, when solar water heater water tank water level during to the float certain position, float rises and drives the valve block rising, blocks controller inner inlet mouth, gives and closes tap water pressure, stifled tight controller inner inlet mouth stops into water.During bathing, close taps on the mixing valve, open the mixing valve drainage switch, because solar water heater water tank one end water level height, mixing valve one end water level is low, produces downward suction in the hot water pipeline, the inner valve block of controller is opened in suction, and pipeline is logical, the solar water heater water tank draining.

Claims

1, a kind of automatic water level controller, it is made up of float, connecting rod, valve block and controller main body, it is characterized in that float be the hollow of a thinner closed at both ends or in fill the less material of density pipe make, it can pierce into solar water heater water tank water inlet endoporus.

2, a kind of automatic water level controller as claimed in claim 1, water inlet have short cylinder at sidepiece in the middle of the valve block top.
