Problems solved by technology

[0004] In the prior art, there are also valves for anti-scaling and descaling by other physical or chemical methods, but most of the existing anti-scaling and descaling valves are complex in structure, large in size, and inconvenient to install, and the existing anti-scaling and descaling valves are redesigned special-shaped valves. The valve is not conducive to direct installation and application in factories or homes; its anti-scaling and descaling components cannot be replaced when the valve is in use or working, and can only be removed and repaired after the valve is found to be blocked or the equipment connected to the valve is faulty Replacement will have a very adverse impact on the life of the equipment and the production speed of the factory, resulting in equipment damage and shutdown; and most of these anti-scaling valves are one-way conduction structures, without multi-functionality and intelligence

Abstract

The invention provides an anti-scale valve. The anti-scale valve comprises a valve body, a valve element mounted in a valve cavity of the valve body, and anti-scale units mounted on the valve body. The valve element is connected with a valve shaft at the bottom of the valve body and comprises an arc surface matched with the inner surface of the valve cavity. A valve rod controlling the valve element to rotate is mounted on the valve element. A handle is mounted at the end, stretching out of the valve body, of the valve rod. Each anti-scale unit comprises a first through opening and a second through opening which are formed in the valve body. A sealing shell is mounted on each through opening. Driving units are mounted on the sealing shells. Anti-scale parts are mounted in the sealing shells. The anti-scale units of the anti-scale valve can be replaced at any time, a standby anti-scale unit is always prepared so that a damaged or ineffective anti-scale unit can be replaced at any time,and the damaged or ineffective anti-scale unit can be blocked accurately through the handle without affecting normal operation of equipment no matter whether the valve is opened or closed.

Description

Technical field [0001] The invention belongs to the field of valve equipment, and particularly relates to an anti-scaling valve. Background technique [0002] In our country, due to the needs of environmental protection, industrial recycled water is mostly used in a closed cycle. In the process of repeated use, water will evaporate and leak and consume some. Therefore, people will replenish the circulating water as needed. Groundwater (especially in northern areas) is mostly used for the supplement of circulating water. Because some salt substances are dissolved in the water to varying degrees, such as CaCO3, MgCO3, etc. They all exist in the form of charged ions. When the solute concentration increases, under the circumstances that the thermodynamic conditions such as temperature and pressure change, solid substances insoluble in water will precipitate out of the water and adhere to the surfaces of pipes and valves. This phenomenon is commonly called "scaling". After the p...
