Problems solved by technology

[0005] Beneficial effects of the present invention: effectively solve the problems of air blockage and residual water caused by U-shaped bending of pipelines in the solar water heater pipeline system, so that the When the shower head is in the shower, the water flow rate is fast, the water volume is large, the water pressure is strong, and the water discharge is always stable; when the hot water is turned off, and after the shower head has drained the water, the invention will automatically store the remaining water in the U-shaped elbow. The emptying, its emptying speed from slow to fast, until quickly finished

Embodiment Construction

[0010] like figure 1 , 2 As shown, the present invention includes a valve body 4, and a valve stem 5 and a hollow adjusting bolt 10 are arranged in the inner cavity of the valve body 4 . The valve stem 5 is in the shape of a boss with a large top and a small bottom, that is, the diameter of the upper cylinder of the valve stem is greater than the diameter of the lower cylinder, and the upper opening is open and the bottom is closed. A plurality of drainage and deflation outlet holes 6 are arranged on the periphery of the valve stem wall, and are arranged in a circular shape around the cylindrical body under the boss of the valve stem 5 . A valve rubber sleeve 8 is arranged between the inner wall of the valve body 4 and the outer wall of the valve rod 5 . The inner edge of the valve rubber sleeve 8 is affixed to the upper periphery of the valve stem 5, and the outer edge of the valve rubber sleeve 8 is affixed to the lower periphery of the inner cavity of the valve body 4 th...

Abstract

The invention relates to an evacuation air-bleed water-drain valve device which comprises a valve body. A valve rod and a hollow adjusting bolt are arranged in a cavity of the valve body, the valve rod is of a big-top small-bottom boss cylinder shape, the upper part of the valve rod is opened and the bottom of the valve rod is closed, and water-drain air-bleed holes are arranged in the wall of the valve rod. A rubber valve sleeve is arranged between the inner wall of valve body and the outer wall of the valve rod, and the cavity of the valve body is divided into two cavities by the rubber valve sleeve, wherein the cavity above the rubber valve sleeve is an input cavity, and the cavity below the rubber valve sleeve is an output cavity. The hollow adjusting bolt is in thread connection with the lower opening of the valve body, the upper end of the hollow adjusting bolt is butted against the bottom of the valve rod, and the water-drain air-bleed holes are distributed over the upper part of the hollow adjusting bolt. The invention can solve the problems of air blockage and water deposit in U-shaped pipes in a solar water heater pipeline system.

Description

technical field [0001] The invention relates to a valve, in particular to a valve device used in a solar water heater system for evacuating air and water. Background technique [0002] Solar water heater is an energy storage device that collects and utilizes solar light and heat. Although simple, it is very effective. Its energy-saving advantages are difficult to replace by other water heaters. However, due to the immature technology of the existing solar water heater pipeline systems, most of the water tanks still use a simple double-pipe water discharge method, that is, an overflow signal pipe and an upper and lower water pipe, and the upper and lower water pipes are always full when not in use. Cold water, when the water starts to be used, a large amount of cold water will be released. The longer the pipeline, the more cold water will be, resulting in a lot of waste of water resources. At the same time, the water pipes are frozen and blocked in cold winter, which causes e...
