Problems solved by technology
Most of the traditional angle valves are made of copper. Drinking water flowing through the inner cavity of the angle valve will produce certain metal precipitate pollution, which cannot meet the lead-free requirements of the new national standard. Moreover, the valve core must be installed in the angle valve to ensure the sealing, resulting in a complicated internal structure. Difficult casting, low yield

The invention discloses a novel lead-free corner valve which comprises a stainless steel body. The body is provided with an inner cavity used for accommodating a valve element, a water inlet and a water outlet are formed in the body, the upper end of the inner cavity is connected with a gland used for pressing the valve element, a plastic liner is mounted in the inner cavity, a mounting oblique plane is arranged at the lower end of the inner cavity, the plastic liner is provided with an oblique plane matched with the mounting oblique plane, the plastic liner is provided with a first sealing ring and a second sealing ring, the first sealing ring is used for sealing the plastic liner and the inner cavity, and the second sealing ring is used for sealing the plastic liner and the water inlet. The novel lead-free corner valve is lead free, environmentally friendly, and suitable for modern environmental-friendly healthy life.
Description
technical field [0001] The invention relates to a novel lead-free angle valve. Background technique [0002] With the improvement of living standards, people pay more and more attention to the pursuit of health, and the cleanliness and safety of drinking water is one of the most important items. Most of the traditional angle valves are made of copper. Drinking water flowing through the inner cavity of the angle valve will produce certain metal precipitate pollution, which cannot meet the lead-free requirements of the new national standard. Moreover, the valve core must be installed in the angle valve to ensure the sealing, resulting in a complicated internal structure. Casting is difficult and the yield rate is low. In order to prevent excessive heavy metals in drinking water, especially to eliminate lead pollution, it is necessary to develop a new type of lead-free angle valve to meet people's pursuit of health. Contents of the invention [0003] In order to overcome t...
