Emptying out of hot water solar water heater valve to help
.
was born a few decades, most current s have also been popular for over 20 years, many changes in solar water heaters, from the exterior to interior. At the same time has not changed is the solar water heater installed in the roof, through the user\\ s water supply piping and connected, as is always water in the pipe, and the water will not heat up, so the user must first put some cold water before use, after the water user cooling water inside the tubes will, cold water from the roof of the higher users more northern areas, poor insulation will lead to frozen pipes, and even then the user can install and use high-rise.
To address these problems, and technical personnel to design emptying valve for the hot water pipes run out, opened on the next release of hot water, but now commonly used on the solar water heater drain valve will not only the formation of \"U\"-shaped bend of the pipe full of water release, but if a \"U\"-shaped bend and then turn on the water pipes may be placed next no hot water.
Solar water heater installed in the roof, through the user\\ s water supply piping and connected, the users normal use, the solar water heater installed in the roof with the user\\ s water supply hot water to form a tower, when the user opens the form of hot water when negative pressure, the longer the pipe the greater the negative pressure. When venting hot water inside the tubes, there is no negative pressure, the pressure at a time when the solar water heater tank diameter is 31 ~ 36CM (usually the diameter of the tank) a high degree of positive pressure – because the emptying valve is installed in the tank outlet, and tank less water pressure is smaller, with H1 to facilitate the description of the following representatives of the height of the tank water.
Solar water heater hot water pipes into the household, in order to always be beautiful from the lower (ground) to go, and again when it reaches the basin upward position, so that hot water basin will be higher than some of the valve on the hot water pipes to These valves will be hidden in the basin below, which not only beautiful, but easy maintenance, upward extension of the hot water pipes are generally higher than the hot water pipe 15 ~ 50CM, which is called \"U\"-shaped tube, to facilitate the description of the following with H2 on behalf of \"U\" shaped tube height. It is this \"U\" shaped tube exist, leading to the use of solar water heater drain valve to drain the pipeline after the \"U\"-shaped tube in the water did not break out, there may be no next time when you put water with hot water. Current common practice is the lowest in the customer premises to install a hot water pipes or electric valve manual drain valve, but more waste water, and very convenient, the cost is high, also if the hot water pipe coming from the ground no less point, the U-shaped pipe can not be emptied of water.
Thus, when the user re-use hot water, because there is no water, housing and outer pipe only gas, but gas is compressible, with a certain degree of flexibility, is not conducive to water, solar water heater tank and pipe remaining in the house water to form U-shaped pipe pressure balance, when H1> H2 when the hot water can be released, but the pressure is too slow; when H1 ≤ H2 put hot water when not, which is now often said, \"U\" tube can not be used emptying valve of the reason, it has become difficult to solve the field of solar water heaters is a major technical challenge, but also solar water heater as electric and gas water heaters by the user eye gaze reasons.
In view of these shortcomings of existing technology, need to adopt a new type of drain valve is a barrier to be able to exist in the solar water heater pipe U-bend when water can be successfully released.
Yangzhou handsome Internet Technology Development Center has developed a solar hot water heater drain valve is a barrier to overcome the shortcomings of existing technology, to ensure that there pipe solar water heater when the U-shaped bend smoothly to release water, ensure that all users can install and use and can quickly use to hot water. The product, with water temperature and heating control, the valve is still done on the structure of innovation, the switch valve blocks the water inside the water tank and easy wide seal leakage, and then have to make because it is sealed with a silicone rubber pad so afraid of furring, more reliable motor as the driving force.
