Abstract
The utility model relates to an automatic drain valve for solar water heater. The automatic drain valve comprises a valve body which is provided with a water inlet, a water outlet and a drain port and is also internally provided with a valve core, wherein the valve body is fixedly equipped with a driving box which is provided with a driving motor, the driving motor is in transmission connection with an output gear mounted in the driving box, a gear shaft of the output gear is matched with a valve core shaft of the valve body in a manner of mortise and tenon, the output gear is fixedly equipped with a pressure rod, and a micro-active switch is arranged at the position corresponding to the pressure rod and is connected with the driving motor via a control circuit. The automatic drain valve for solar water heater is capable of closing the water outlet and the drain port individually and has no influence on water intake and exhaust of the water heater after the drain port is closed; the drain port is opened automatically while the water outlet is closed, thus the water in pipeline can be drained. The automatic drain valve for solar water heater has simple structure and convenient maintenance and installation.
Description
Technical field
The utility model relates to the automatic exhaust-valve of solar water heater.
Background technique
The Shang Shui of solar water heater and following hydromining are so not only saved cost with same pipeline, also are convenient to install.But the drawback of bringing thus is this follows in the pipeline, at first emits ducted cold water during use and just can go out hot water.Also easily pipeline is frozen in winter, cause and to use.In order to prevent to freeze pipeline, can only so not only cause the waste of water resources in advance with the water emptying in the whole water tank, also can't use solar water heater in winter.
Summary of the invention
The purpose of this utility model provide a kind of in can emptying pipe water and don't influence the automatic exhaust-valve of solar water heater of the use of hot water in the water tank.
For achieving the above object, the utility model is by the following technical solutions:
The automatic exhaust-valve of solar water heater described in the utility model comprises the valve body that has water intake, water outlet, evacuation port, be provided with spool in the valve body, it is characterized in that: be installed with the driving box on the valve body, drive box and be provided with drive motor, drive motor is in transmission connection with the output gear that is installed in the driving box, the gear shaft of output gear cooperates with the poppet shaft mortise and tenon of valve body, be installed with press rods on the output gear, be provided with sensitive switch in the position corresponding with press rods, sensitive switch is connected with drive motor by control circuit.
The automatic exhaust-valve of this solar water heater can be closed water outlet and evacuation port separately, closes after the evacuation port, does not influence water heater water up and down; Automatically open evacuation port when closing water outlet, can be with ducted water emptying.Simple in structure, be convenient to safeguard and install.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model a structural representation;
Fig. 2 is the plan view that Fig. 1 embodiment drives box.
Embodiment
As shown in drawings, the automatic exhaust-valve of solar water heater described in the utility model comprises the valve body 4 that has water intake 1, water outlet 2, evacuation port 3, is provided with spool in the valve body 4.Passage is set on the spool, make spool the rotation in water intake 1 respectively with water outlet 2 or evacuation port 3 conductings, be that spool is in the time of water outlet 2 rotations, evacuation port 3 is closed, water intake 1 and water outlet 2 conductings, spool is in the time of evacuation port 3 rotations, and water outlet 2 is closed, water intake 1 and evacuation port 3 conductings.The structure of this spool is a known technology, no longer describes in detail.
On valve body 4, be installed with and drive box 5, drive box 5 and be provided with drive motor 8, drive motor 8 is in transmission connection with the output gear 6 that is installed in the driving box 5, the gear shaft of output gear 6 cooperates with the poppet shaft mortise and tenon of valve body 4, be installed with press rods 7 on the output gear 6, the through hole 11 that on the lid of the driving box 5 above the press rods 7, has circular arc, press rods 7 is passed through hole 11 and is stretched out driving box 5, drive on the lid of box 5, the position corresponding with press rods 7 be provided with sensitive switch 9, sensitive switch 9 is connected with drive motor 8 by control circuit.Sensitive switch 9 has two, is installed in respectively on two end points of through hole 11, is defined as water management end and emptying control end.When drive motor 8 drive output gears 6 rotate forward or backwards, move back and forth between two end points of press rods 7 in through hole 11.When moving to a certain end points, press rods 7 is touched corresponding sensitive switch 9, gives signal of control circuit, when control circuit has a power failure the control motor, will instruct corresponding water supply valve door or emptying valve event.When needing the conversion work state, control circuit control makes the counter-rotating of control motor, touches the sensitive switch of opposite side up to press rods 7.So just can realize the automatic emptying of solar water heater, not hinder normal use.
The structure of control circuit need not to describe in detail at this.
During use, water intake 1 connects upper and lower conduit, and water outlet 2 connects solar water container, and evacuation port 3 opens wide.
