Abstract
The utility model relates to a solar drainage device, in particular to a solar special pipeline emptying valve which can control the emptying of a pipeline. The pipeline emptying valve comprises a motor, a valve body arranged outside a water box, a switch plug, an air inlet hole, a water inlet and a water outlet; one end of the valve body is provided with the water inlet and the water outlet; theupper part of the valve body is provided with the air inlet hole; the valve body is internally provided with a chamber piston; the valve body at the upper part of the piston is internally provided with the switch plug which limits the stroke of the piston; the valve body at the lower part of the piston is internally provided with the switch plug that limits the stroke of the piston; and the upperswitch plug and the lower switch plug are hollow chambers. The solar special pipeline emptying valve has the advantages of simple structure, low cost, convenient installation and strong practicability, and is beneficial to the popularization of solar water heaters.
Description
Technical field
The utility model relates to the solar energy drainage arrangement, but relates in particular to a kind of special solar pipe exhaust-valve of control piper emptying.
Background technology
Solar water heater is owing to save the energy, safety and sanitation, advantage such as easy to use is very popular, but because northern area is colder, use winter solar water heater to exist upper and lower waterpipe and freeze stifled problem, this problem fails to obtain satisfied solution for many years always, adopt basically now and bleed off to avoid freezing the water in the pipeline stifled, existing exhaust-valve must be opened exhaust-valve earlier could go up water, complex operation, the fault rate height, the use that has even influence solar water heater has a negative impact.
Summary of the invention
For solving above-mentioned deficiency, the purpose of this utility model is to provide a kind of dependable performance, and is simple in structure, practical, easy to use, long-lived special solar pipe exhaust-valve.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of special solar pipe exhaust-valve, it comprises motor, be installed in the valve body of water tank, the switch stopper, air admission hole, intake-outlet, one end of this valve body is an intake-outlet, the top of valve body is provided with air admission hole, and a cavity piston is installed in the described valve body, is provided with the switch stopper that the plug stroke is drawn together in restriction in the valve body on this piston top, be provided with the switch stopper of limited piston stroke in the valve body of this piston bottom, said going up in switch stopper and the following switch stopper is cavity.During the utility model work, switch stopper in the connection, the switch stopper moves up under the motor effect, and delivery port is opened, the hot water of water tank flows in the upper and lower conduit inlet chamber, when connecting the cock plug period of the day from 11 p.m. to 1 a.m down, the switch stopper moves down under the motor effect, and delivery port is closed, open indoor hot water tap this moment, water emptying in the upper and lower conduit can be prevented that effectively pipeline from freezing stifled phenomenon, easy to use.
The utlity model has simple in structurely, with low cost, easy for installation, practical, help popularizing of solar water heater.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure, motor 1, valve body 2, cavity piston 3, switch stopper 4, air admission hole 5 connects solar water pipe 6, sealing ring 7, intake-outlet 8, switch stopper air admission hole 9,10, connecting shaft 11.
The specific embodiment
As shown in the figure, a kind of special solar pipe exhaust-valve, it comprises motor 1, be installed in the outer valve body 2 of water tank, switch stopper 4, air admission hole 5, intake-outlet 8, one end of valve body 2 is an intake-outlet 8, the top of valve body 2 is provided with air admission hole 5, in the described valve body 2 cavity piston 3 is installed, and is provided with the switch stopper 4 that the plug stroke is drawn together in restriction in the valve body 2 on these piston 3 tops, be provided with the switch stopper 4 of limited piston stroke in the valve body 2 of these piston 3 bottoms, said going up in switch stopper and the following switch stopper is cavity.During the utility model work, switch stopper 4 in the connection, switch stopper 4 moves up under motor 1 effect, and delivery port is opened, the hot water of water tank flows in the upper and lower conduit inlet chamber, when connecting cock plug 4 period of the day from 11 p.m. to 1 a.m down, switch stopper 4 moves down under motor 1 effect, and delivery port is closed, open indoor hot water tap this moment, water emptying in the upper and lower conduit can be prevented that effectively pipeline from freezing stifled phenomenon, easy to use.
