Abstract
This utility model discloses one kind of pipe discharge air valve for solar water heater, consisting of valve body, water inlet, water outlet, rubber diaphragm, upper fixing magnetizer, lower fixing magnetizer, coil, coil brace, moving magnetizer, guide rod, coil case and spring; the top of valve body is equipped with concavity to be connected with water outlet, and the rubber diaphragm is installed in the concavity; the bottom of lower fixing magnetizer is installed in the concavity and compresses the circle of rubber diaphragm, and the lower fixing magnetizer and upper fixing magnetizer are respectively connected with the coil brace; the coil sleeve is installed at the exterior of coil brace, the spring is installed on the lower fixing magnetizer; guide rod is connected with the moving magnetizer, the bottom of moving magnetizer is on the spring, the moving magnetizer is installed in the coil brace and on the top of lower fixing magnetizer. The remaining water in the water pipe can be discharged by utilizing this utility model discharge air valve, which not only saves water resources and is more convenient for use, but also the connection pipe can't be frosted crack owing to the water in it, so that the solar water heater can be preferably applicable to cold environment.
Description
Technical field
The utility model relates to a kind of pipe line evacuation valve that is applied to solar water heater, can connects the surplus water emptying in the water pipe.
Background technique
The water tank of solar water heater is loaded on outdoor daylighting position (generally all placing top of building) preferably, and it need link to each other with interior conduit with one section long connection water pipe.Like this, during the hot water of user in using water tank, the cold water that needs will connect earlier in the water pipe bleeds off, and not only causes the waste of water resources, and uses inconvenience, loses time, and is also easy to catch cold when having a bath.Simultaneously, northern area in cold in winter, because outdoor temperature is too low, for avoiding inside the connection water pipe of water to be arranged by bursting by freezing, need outside water pipe, bind heating tape, make that it is unlikely that Yin Wendu is low excessively, the water freezing in the pipeline and by bursting by freezing, but so just improved the user cost of solar water heater, influenced solar water heater applying at northern area.
Summary of the invention
Technical problem to be solved in the utility model be to propose a kind of can be with the surplus water emptying that connects in the water pipe, the conserve water resource, easy to use, can make solar water heater be applicable to the solar water heater pipe line evacuation valve of cold environment better.
For solving the problems of the technologies described above, the utility model solar water heater comprises valve body with pipe line evacuation valve, water intake, water outlet, diaphragm of rubber, last fixed magnetizer, following fixed magnetizer, coil, coil brace, mobile magnet case, guide rod, coil case and spring, described water intake is located at the side of described valve body, described water outlet is located at the lower end of described valve body, the upper end of described valve body is provided with recess and communicates with described water outlet, described diaphragm of rubber places in this recess, the described lower end of fixed magnetizer down places the periphery of pushing down described diaphragm of rubber in the described recess, described fixed magnetizer down links to each other with described coil brace respectively with the described fixed magnetizer of going up, described coil is sheathed on the outside of described coil brace, described spring is located on the described fixed magnetizer down, described guide rod and described mobile magnet case are fixedly linked, the lower end of described mobile magnet case is against on the described spring, and described mobile magnet case places in the described coil brace, the described upper end of fixed magnetizer down.
Above-mentioned solar water heater pipe line evacuation valve, it also includes silica gel sheath, and this silica gel sheath is locked on the upper end portion of described guide rod, and it is positioned at the upper end of described mobile magnet case.
Above-mentioned solar water heater pipe line evacuation valve is respectively equipped with seal ring at described coil brace and the described joint of joint, described guide rod and the described mobile magnet case of fixed magnetizer down.
Above-mentioned solar water heater pipe line evacuation valve, described guide rod are hollow.
The utility model is owing to adopted above-mentioned technical pattern, during installation, water intake is linked to each other with the water outlet of solar water heater water tank, with water outlet be connected water pipe and link to each other, the power control switch of coil is located at user's indoor (can establish separately, also can be located on the solar water heater observing and controlling instrument commonly used at present).After hot water uses up, open coil power, between upper and lower fixed magnetizer, produce magnetic field, mobile magnet case quilt fixed magnetizer is down down inhaled, and drives guide rod and moves down, and promotes diaphragm of rubber toward pressing down, and water outlet is blocked.Like this, the hot water in the water tank just can not connect water pipe by this flow direction valve.The surplus water that connects in the water pipe just can be drained.In the time of need reusing hot water, disconnect coil power by switch, magnetic field between then upper and lower fixed magnetizer disappears, mobile magnet case and guide rod be up motion under the effect of spring restoring force, diaphragm of rubber upwards resets simultaneously, hot water just can flow to by water outlet and connect in the water pipe, and it is indoor for use to enter the user.Since before connect and do not contain cold water in the water pipe, so hot water can directly come out, and saved water resources, uses more conveniently, and connects water pipe also can water not arranged by bursting by freezing because of inside under the environmental conditions of cold.The setting of silica gel sheath and seal ring can further improve the whole airtight performance of valve, prevents the generation of water leakage phenomenon better.Guide rod is set to hollow, can be after closing hot water, utilize outdoor air pressure will connect in the water pipe surplus water rapidly, drain up hill and dale.
