Abstract
The utility model discloses a solar water heater emptying valve, in particular relates to a solar water heater emptying valve provided with a filtering screen assembly. The filtering screen assembly is arranged on the solar water heater emptying valve, the filtering screen assembly and a valve body are connected and fixed by screws, so that the purposes of preventing scale from entering the emptying valve is achieved, adverse effect of the scale in a volumetric water tank on normal usage of the emptying valve is effectively solved, and the working reliability of the emptying valve is improved.
Description
Technical field
The utility model relates to a kind of solar water heater emptying valve, especially a kind of solar water heater emptying valve that net-filter assembly is arranged.
Background technique
The positive displacement water tank is the hot water storage equipment of solar water heater; In use, the water temperature in the positive displacement water tank will produce fouling after surpassing 60 ℃, during the exhaust-valve water outlet of incrusted deposit in water tank; Can stop up water outlet, the normal use of exhaust-valve is had a negative impact.
In the solar water heater emptying valve that generally uses on the market now, all do not have the device of designing and arranging scale removal, in case the intake-outlet of solar water heater emptying valve is stopped up by incrustation scale, exhaust-valve breaks down, and will cause that solar water heater lost efficacy, and can not use.
Application number is among " pipe line evacuation valve " (notice of authorization CN101598222B) of 200910032587.3; And application number is " pipeline emptying valve for solar water heater " (application publication number CN101737527A) of 200810180906.0, in the disclosed technological scheme, waterproof scale device is not installed all; Exhaust-valve in use like this; In case intake-outlet is stopped up by incrustation scale, whole solar energy will lose efficacy or valve body damages, and the maintenance failure rate raises greatly; Have a strong impact on promoting the use of of exhaust-valve technology, more be unfavorable for the popularization and the use of solar water heater.
Summary of the invention
For improving the reliability of solar water heater emptying valve; On the described solar water heater emptying valve of the utility model net-filter assembly has been installed; Like this, in the solar water heater emptying valve using process, just the incrustation scale that produces in the positive displacement water tank can be isolated in the outside of exhaust-valve water outlet; Improve the reliability of solar water heater emptying valve, prolonged the complete machine working life of solar water heater emptying valve.
The utility model solves the technological scheme that its technical problem adopted: on the solar water heater emptying valve valve body, a net-filter assembly is installed, is connected with valve body and fixes through screw thread, reach the purpose of isolation incrustation scale entering exhaust-valve.
The beneficial effect of the utility model is: efficiently solve incrustation scale in the positive displacement water tank to the normal adverse effect of using of exhaust-valve, improved the functional reliability of exhaust-valve.

Specific embodiment:
Below in conjunction with description of drawings embodiment.
Fig. 7 is the solar water heater emptying valve that net-filter assembly is arranged, and is made up of net-filter assembly and valve body (7).The net-filter assembly of being made up of strainer body (1), end cap (2) has been installed on the valve body (7) of solar water heater emptying valve, and an end of strainer body (1) has strainer body screw thread (3), and strainer body (1) is made by latticed or circular hole filter screen.Strainer body (1) is connected through strainer body screw thread (3) valve body screw thread (6) with valve body (7) to be fixed, and outlet pipe (5) passes from the mouth of pipe (4) of strainer body (1) and end cap (2).So just can realize that the incrustation scale in the positive displacement water tank intercepts the outside in valve body (7), the purpose of raising exhaust-valve functional reliability effectively.
Fig. 2 is the embodiment of the utility model: end cap (2) is in the outside of strainer body (1);
Fig. 8 is the embodiment of the utility model: strainer body (1) is for latticed;
Fig. 9 is the embodiment of the utility model: strainer body (1) is a cone shape;
Figure 10 is the embodiment of the utility model: strainer body (1) does not use end cap (2) for hemispheric, and the mouth of pipe (4) is directly opened the top in strainer body (1);
Figure 11 is the embodiment of the utility model: strainer body (1) is a streamline, does not use end cap (2), and the mouth of pipe (4) is directly opened the top in strainer body (1).
