Description

The solar water heater inlet controller

Technical field

A kind of water inlet controller, especially a kind of solar water heater inlet controller.

Background technology

As everyone knows, general solar water heater is placed on from roof far away, the pond of having a bath, from the overflow pipe of roof solar water tank, lead to the pool side of having a bath by a very long flexible pipe, during the water tank water intake of emptying, the water that people must be careful in the Radiator overflow hose overflows from flexible pipe, close water inlet pipe valve in the bath room when treating to have in the flexible pipe water to overflow, otherwise water one direct current from overflow pipe is decreased, this just increases the many troubles of user; Though the water heater that has adopt electrical equipment control or in establish ball float and close inlet valve automatically, the former needs power supply, the latter is placed on ball valve in the water tank, unfavorable maintenance.

Summary of the invention

The purpose of this utility model is: release a kind of not electrical appliance and ball float, also can control the device of solar water heater water tank water inlet automatically.

The purpose of this utility model is achieved in that it comprises a shell, the shell below is fixed with connecting bend, the connecting bend lower end is the overflow pipe joint, the water supply connector and the water out adapter of fine motion water valve fixed on shell two limits, it is characterized in that: the overflow pipe of the below water receiving case of overflow pipe joint, connecting bend one end is inserted in the top of overflow pipe joint, another termination bellows lower port of connecting bend, the upper port of bellows inserts the bottom tube of the water drum that has pore, also affixed the spring that makes the water drum upper and lower displacement between water drum and shell, a limit of water drum upper and lower displacement can offset with the feeler lever of fine motion water valve.

Like this under the effect of spring power, make water drum to top offset, the feeler lever that can make the fine motion water valve open or close is promptly upwards oppressed on the displacement limit of water drum, at this moment make the fine motion water valve be in opening behind the feeler lever pressurized, after the user is linked into water supply connector with running water pipe, running water is linked into the solar water container water inlet pipe through fine motion water valve and water out adapter, and water tank is promptly intake.When water is filled in water tank, water from the overflow pipe of water tank through the overflow pipe joint, connecting bend and bellows arrive water drum, water in the water drum is increased sharply, water is heavy in the tube also soon increases, because bellows is the soft pipe of a shape bending, it is heavy to be difficult to support water, so water drum will be oppressed the spring power that makes its rising originally and be descended, cause above the water drum between the position that props up feeler lever on the fine motion water valve originally and feeler lever and gradually become the disengaging shape, because the feeler lever of fine motion water valve no longer is under pressure, so the fine motion water valve promptly enters into by the unlatching shape and cuts out shape, solar water container promptly stops into water.Cistern water level descends when water, and the water in the water drum also from top to bottom flow back in the water tank, and water drum gravity reduces, water drum is made progress under the effect of spring power again, water drum is oppressed the feeler lever of fine motion water valve again, and the fine motion water valve is opened again, and water tank will be intake once more.If the user does not want to allow the hot water temperature decrease because of water inlet in having a bath, then can before the fine motion water valve, increase common water valve that the people that has a bath is convenient to control and close water inlet when having a bath.Owing to can control the pass valve automatically after the water inlet of above-mentioned controller, and without power supply, also do not resemble and need put into the very high water tank of water temperature the ball-cock assembly, and take space in the water tank, therefore reached the purpose of design of utility model.

Description of drawings

Fig. 1 is the schematic diagram of a kind of controller of the utility model.

Fig. 2 is the fundamental diagram that this controller is connected with solar water container.

The specific embodiment

Among Fig. 11 is the overflow pipe joint, the 2nd, and connecting bend, the 3rd, spring, the 4th, water drum, the 5th, water out adapter, the 6th, fine motion water valve, the 7th, feeler lever, the 8th, pore, the 9th, water supply connector, the 10th, shell, the 11st, bottom tube, the 12nd, bellows, the 13rd, shell small opening.

Two limits are connected with water out adapter 5 and water supply connector 9 about shell 10 tops, the below of shell is fixed with connecting bend 2, connecting bend 2 lower ends and overflow pipe join, the last right-hand member of connecting bend 2 is connecting bellows 12, the upper end of bellows 12 laterally is enclosed within on the bottom tube 11 that has elbow, bottom and water drum 4 that bottom tube 11 is connected water drum 4 communicate, and become the part that water drum 4 is filled with water.Between the last plane of the bottom of the lower plane of water drum 4 and shell 10 spring 3 is housed, spring 3 is pushed water drum 4 to top, the elastic force of spring 3 need be selected and be selected in: can make when not having water in the tube that the middle part pushes against feeler lever 7 above the water drum, fine motion water valve 6 is opened, and spring power can not push against feeler lever 7 when the water of a great deal of is arranged in the tube, and can only slightly contact or contact lever 7 not, so fine motion water valve 6 cuts out.The pore 8 that is in the shell small opening 13 on the shell and is on the water drum designs in order to make the logical atmosphere of water in the water drum 4.
